PREFACE 

The National Frontiers of Engineering (NatFoE) Symposium, for Young Engineers, is the flagship event of the Indian National Academy of Engineering (INAE). The purpose of this annual symposium is to provide a forum for outstanding young engineers, from universities, industries and government labs to exchange recent technical advances in the country, with peers and leaders, across a range of engineering disciplines. About 35 outstanding engineers under the age of 45 have been invited for this intensive two and half day symposium, to discuss cutting edge developments in four contemporary areas of engineering in the Indian context – Engineering in Daily Life, Engineering in National Development, Engineering in Research and Innovations in Engineering.

The format of the event is designed to have equal representation from Academia and Industry. It is intended to facilitate cross functional interactions and networking between the participants, covering sectors of power, healthcare, water, education, infrastructure, communication, etc. and promotes transfer of new approaches across different engineering fields. The symposia will enable informal one-on-one discussions among participants. Speakers will emphasize on current cutting-edge research in their disciplines to colleagues outside their field, highlight some of the limitations, and predict the future technology implications of these areas towards a rapidly developing India.

A panel discussion on “How to help young engineers succeed in their engineering endeavours”, is expected to bring out some of the best experiences in achieving a successful career in engineering. Pre-Dinner talk, “In the Life of an Engineer” by Dr. Srikumar Banerjee, is well aligned with the theme of the symposium. It has been arranged to inspire and motivate the young engineers, to strive towards pinnacles of achievement in their respective engineering careers.

Acknowledgements are due to the office of INAE, Brig. S.C. Marwaha, Brig. Ranjan Minocha and their team. In particular, Dr. Geethanjali Sawhney for helping with all the flight bookings and Ms. Pratigya Laur for support with other logistics associated with this symposium. We would also like to thank Prof. C.V.R. Murty, fellow INAE, for his mentorship in organizing 7NatFoE.

This symposium would not have been possible without the support of the administration, faculty members, and scientific staff from IIT Guwahati. We would also like to recognize the extensive support from students in enabling organizing a successful meeting.

About the Four Themes of 7NatFoE

(a) Engineering in Daily Life (e.g., Laptops, Cell phones, TVs, Robots, Intelligent Buildings and Smart Houses) Advances in engineering fields that have significant and positive impact on quality and requirements of daily life are required to be achieved for solving simple day-to-day problems and for reducing the cost of living. Improving the performance of electronic gadgets, for example, laptops, cell phones, television, music players, robots, etc., improving the battery life of such products, using new and cost effective materials for speedy construction of intelligent buildings and smart houses, fuel efficiency, working towards greener and cleaner environment, development of smarter and safer automobiles, creation of better health facilities, etc are some of the important and necessary goals that may be fulfilled if engineers from different backgrounds and expertise work together.

(b) Engineering in National Development (e.g., Urban Housing and Infrastructure, sustainable cities, power, water, transportation, Healthcare)

Efficient and optimized use of water, electricity, agriculture, communication, construction materials and methods, minerals, and other natural resources is required for sustained development of our Nation. Development of new techniques and optimization of efficiency of existing techniques for power generation (hydropower, thermal power, solar power, wind power, nuclear power, etc.) and its usage is extremely important for providing power to different parts of India. Similarly, providing safe drinking water, sanitation facilities, economical and safe housing, inexpensive food products, etc is urgently required in vast areas of India. We must become self sustainable as far as availability of food products and energy is considered. These objectives can only be achieved through continuous efforts of engineers working in different fields.

(c) Research in Engineering (e.g., impediments to engineering research, translating engineering research into practice)

While improving the existing systems and techniques for solving day-to-day life problems is essential, it is also very important and necessary to look for additional possible avenues in different fields by continuing research and then translating the research into practice. Several impediments are generally associated with such engineering research and many such problems can be overcome by working in a group. Working in those fields that have direct implications in practice is the need of the hour. Search for alternative sources for fuel, water, power, communication, food, electronics, etc., must be continued and encouraged. Research on development of light and strong materials, chemicals used in variety of fields, smaller and efficient electronics, green technologies, etc is essential for effective utilization of natural resources.

(d) Innovations in Engineering (e.g., Creativity and Excellence in engineering education and practice) Expansion of knowledge is essential for innovations in research and development, automation, and growth of higher education. Excellence in engineering education, in turn, is required for imparting required knowledge to younger generations. Development of creative methods of teaching and learning basic fundamentals in not only engineering fields but also at lower levels (in schools) will increase awareness of young minds towards technology, health, science, society, and ethical issues.

Abstract Session I

Renewables are clearly the way ahead! Just as oil and coal were instrumental in supporting industrial growth and economic progress, renewables are now increasingly expected to bear the burden on incessant progress. Unsustainability, including environmental destruction (climate change) and inequitable growth, have undeniably characterised global progress eventually. Renewables, on the contrary are expected to be different and further result in alleviating past mistakes.

However, while the intention of renewable performance is well-accepted (and

ideal), practical ramification of their unbridled adoption could actually lead to counter-intuitive results. These results would have far-reaching environmental and socio-cultural implications given the fact that, just like money, solar energy is also not equitably distributed, but both have a clear bearing on how modern human function globally. The current paper/presentation discusses few such issues pertaining to the adoption of renewables, Solar PV in particular, and also highlights possible avenues for regulated adoption of these technologies for sustainability.

Abstract Session I

One of the major problems facing by society in present day is the waste disposal and its management. This has become great challenge to the local bodies in India from metro cities to municipal towns and time is not so far to reach this even to the villages. Centralised industrialisation and single crop agriculture leads to failure of ecosystem life cycle and accumulate large amount of waste in non manageable form. This centralised activity gives optimal infrastructure use and high productivity for certain period and leads to severe imbalance in the system later on. Therefore initiation should be taken at micro level in all spheres of life to maintain the ecosystem life cycle. This will not only effectively help in managing waste as well as to develop the rural area, reduce migration based population density and improvement in life style and infrastructure. Even-though this will not be a solution for industrial waste management since most of these waste are non degradable in nature. In this context generating bi- products from the composite industrial waste and increase the life time of the materials is discussed.

In present day growing demand to develop light weight structures, the need to use of composite is also growing which leads to generation of hazardous and non –degradable wastes. Composite industry faces great challenges in this regards as it produces wastes in different form from raw materials, process aid consumables and

finishing process which are non degradable in nature. These are available in different forms and stage of chemical reactions such as A, B (half polymerised) or C (fully polymerised). Therefore these materials have to be classified to use in different applications for non structural application like cladding panels, sound and thermal insulator panels etc.

As per general rule of waste management hierarchy, prevention is the best option where as with the present technology it is nearly impossible to achieve this 100%. But optimal use, bunching of multiple parts, non standardised raw material size and standardisation of process aid consumables can bring down the waste to a considerable amount which will fall under second level of management as minimisation. Fibre placement, out of autoclave curing, reusable consumable is future technologies that can reduce the waste to some extent. Even after prevention and minimisation option large amount of waste will be generated based on the complexity, shape and size of part. There will be approximately 7 to 15 % waste in the raw materials in non useable from. Around 0.5 Kg / m2of process aid waste and over and above that a 5% of trim waste will be generated. Apart from these other process supporting materials also will be generated. Presently these non degradable wastes are disposed for land filling the least preferred waste management option.

The waste can be classified as

1. Raw material waste (A or B stage polymerised)

2. Non reusable process aid consumables (partially or fully polymerised )

3. Trim or finishing wastes. (fully polymerised)

Raw materials waste bi-product

The major raw material wastes are carbon, glass and Arimid in form of prepregs or fibres. Around 7 to 15% of raw materials will be wasted during the cutting operation due to ply orientation, shape of part and the roll width. Prepreg waste can be used for making laminates in the same concept of broken tile flooring. Short fibres laminate to be made from the cut wastes with good aesthetics. These laminates will posses good compressive properties and can be used for secondary and tertiary structural for commercial and domestic applications like floor tiles, face sheet for core, cabinet wall, container bodies, false ceiling etc. The fabrics (fibres) can be chopped into short fibres and used for spray layup. Further to that similar process of prepreg can be adopted with appropriate resin system.

Non reusable process aid consumables (partially or fully polymerised)

There are a lot of process aid consumables like bagging film, bleeder, release film breather

etc. These process aid consumables are combination of degradable and non degradable materials. In these materials bagging material and release films are thermoplastics. Therefore all these process aid consumables can be chopped and hot pressed into shapes with appropriate thermoplastic resin system to make core for sandwich panels, seats for public transport etc. Another option for light weight core is by mixing solid waste mixture and thermoplastic resin system with air entrapment. These cores can be concealed with lamination or spray layup to make sandwich panels. These panels can be used for different applications like thermal insulation container walls, low cost housing partition walls, furniture or interior panels etc.

Trim or finishing wastes (Fully polymerised)

The fully polymerised particle and trim waste can be used as fillers in the sandwich core by chopping, reinforcing the asphalt road etc. These can also be used as short reinforcement in different applications based on size and shape of waste members.

These suggestions will enhance the useful life of the waste generated from the composite industry and reduce the disposal waste. By this way the cost involved in the disposal can be reduced which is an additional gain to the industry.

Abstract Session I

Language is the finest communication medium of mankind. We use language for communicating our day to day common needs, for expressing our thoughts and imagination. In Indian mythology Brahma is called the creator of the universe and the word, because of its enormous power, is called Sabda Brahma (Word- the Creator).

Speech and script are the two major wings of language. Speech, the audible form is more ancient than script, the visual form. Study of language, its structure, syntax as well as semantic harmony started more than two thousand years ago by the Greek and Indian philosophers among others. In this context, Ashtadhyayi by Panini is worth-mentioning. It was written sometime between 500 B.C. and 600 B.C. Other notable ancient books are Mahabhasya and Vakyapadiya written by Patanjali and Bartrihari, respectively. The scientific insight shown in these books is outstanding even with respect to the modern standard.

Language engineering is the application of knowledge of language for the development of computer based tools which can recognize, understand, interpret and generate human language in all its forms. Research in language engineering involves various directions of synthesis, storage and analysis of language in both script and speech form is being continued throughout the ages. However, the invention of digital computer provided new dimensions to these studies. Artificial Intelligence, a discipline that explores simulation of intelligent behaviour by computer, gradually evolved. One of the major objectives of this research is to

understand natural language text or speech automatically and synthesize a desirable output.

The talk provides overall idea on language engineering, its major components, and the state of the art of this field. It will show how language engineering has (or will have) a profound impact in our daily life (in future) and illustrate how the advancement in language engineering is an important aid in maintaining cultural diversity in a multi-lingual Indian society.

Abstract Session I

There is no engineering without materials, that’s why one way to categories time span is by the “material” of importance of that era. Middle of the 20th century marks the beginning of the Silicon Age, we are realizing its benefit in terms of communication and information technology. It has changed the way we live and do business. Electronics in daily life is becoming a basic need, not a luxury. In this respect, organic electronics has the potential to start a new era. It has several advantages over silicon technology in terms of low processing temperatures and use of manufacturing techniques like printing for production. This makes organic electronics suitable for applications requiring low manufacturing cost and large area, transparent and flexible substrates. There are already examples of commercial products using organic light emitting diodes based display, and other prototypes have also been demonstrated. eg. radio frequency identification tags, organic solar cells and sensors. It can be said that organic electronics is already established, but to reap the benefit of printed organic electronics (printed electronics) there are still many challenges related to materials, processes and device structure.

My own journey started about 12 years ago; I will first discuss development of polysilane based organic light emitting diodes (OLEDs) for ultra violet emission. We demonstrated several polysilanes that can be used to make UV-OLEDs at room temperature. Molecular structure of the polysilane influences the emission and opto-electronic properties of thin films. Poor efficiency and stability were the major issues with UV

emitting devices. I will also present some results on developing white OLEDs. Next, I will discuss our effort on organic thin film transistors (OTFTs). On device front: (i) we developed the device architecture for photolithography less vertical channel organic thin film transistor to reduce fabrication cost; (ii) We also fabricated organic memory device using an organic ferroelectric material. On materials front: Using simulations we tried to understand dependence of field effect mobility of pentacene based organic thin film transistors (OTFT) on semiconductor thickness and device structure. On processing front: I will discuss some aspects related to materials and processes for flexible and solution processed organic thin film transistors. This opens up new research and development opportunities for engineers.

Finally, I must mention some achievements of our large area electronics group at Samtel Center of Dispaly Technology at IIT Kanpur, such as development of prototype OLED based mobile display, organic photovoltaic cells (OPVs) and modules, sensors, etc. It is a successful tripartite collaboration between academia, industries & government agencies. This technology is headed for providing solution for our energy problems – OPVS are likely to be cost effective compared to other thin film technologies, and white OLEDs are promising for solid state lighting application. OTFTs can be used to print electronic circuits anywhere we want – all pervasive electronics.

Quality of life in modern times is directly correlated to the quality of infrastructure available in the societies and county that we inhabit. The simple example has been the dramatic improvement in commuting times and improvement of air quality in New Delhi since the advent of the Metro Rail system. The role of Nondestructive Testing (NDT) in ensuring the safe and secure operation of infrastructure is well understood. The science of NDT has been making the transition from the analog world to the digital world over the past decade and more work still needs to be done. The re-imagination of NDT for the digital world forms the crux of this abstract which also talks of the need for standard development to come to grips with the changing times. This paper will provide a couple of examples of how lack of standards is a key barrier to the adoption of new technologies.

The first example relates to the testing of pre stressed concrete structures such as bridge decks and tunnels. Traditional methods of inspection such as visual inspection and/or chain drag can only detect corrosion of steel reinforcements only after significant damage has been caused. Though advanced techniques such as Ground Penetrating Radar (GPR), Impact Echo (IE) and Ultrasound ( UT) have been used at the laboratory level with success, this has not yet translated into widespread field use due to the lack of standards. The standards referred here include classical accept and reject criteria as published by standards bodies such as ASME, ASTM and similar European and Japanese authorities.

Abstract Session I

These standards are critical to ensure adoption of modern test techniques across the world and enable certification of inspectors. The necessity of using multiple techniques including GPR, IE and UT to improve Probability of Detection (PoD) of defects in concrete will further enable development of algorithms for Data Fusion which would have applications in other areas too. There are over Six Hundred Thousand concrete bridges in the United States alone which need to be inspected and prioritized for repair and replacement.

The second example relates to the slow adoption of standard data formats such as Diconde in the world of NDT. DICONDE is an evolving standard that provides a way for Nondestructive Evaluation (NDE) manufacturers and users to share image data. Diconde is based on the Dicom standard used in medical imaging since the 1970s and mandated since release of standard in 1983. The subsequent explosion in the development of medical imaging has led to improved diagnostic capability for the benefit of patients. As a by-product this also led to growth of business focused on developing new products and solutions to support the digital wave in medicine. The NDT industry is at the cusp of such an opportunity when Diconde reaches a critical mass.

Abstract Session II

Healthcare is one of the largest growing sectors in India with scope for rapid growth. The Indian healthcare sector currently represents a USD 40 Billion industry. The industry is expected to grow to ~USD 79 Billion by 2012 and ~ USD 280 Billion by 2020. However, India’s healthcare spend is significantly low when compared to the global, developed and other similar emerging economies and when compared on a “percent of GDP” basis is less than half the global average (4.10%). The contribution of the private sector is amongst the highest in the world (~75 percent). Public sector spending is amongst the lowest in the world and is ~23 percentage points lower than the global average.

There is also a growing divide in terms of healthcare access and affordability– one where there is access to high quality medical care for the growing middle-class and medical tourists and the other where a majority of Indians have limited or no access to quality care. However, there is a combination of demographic (rising literacy, disposable income and incidence of lifestyle-related diseases) and economic factors (tax benefits, insurance coverage and medical tourism) that are expected to bring about increased healthcare coverage in India.

While the healthcare sector is poised for growth, it is still affected by issues and challenges. Two major challenges are the increasing “dual disease burden” and the lack of infrastructure and skilled manpower. India is

emerging as the global disease capital for cardiovascular disease, diabetes and other lifestyle diseases. At the same time, the urban poor and rural population continues to suffer from communicable diseases. In addition, there is a higher occurrence of non-communicable lifestyle diseases in rural India. Healthcare delivery and access in India is limited in large parts of the country especially in the rural areas due to either lack of infrastructure or unplanned and irregularly distributed infrastructure. This lack of access is further compounded by lack of skilled manpower to cater to the needs of the vast Indian population. Another area that requires focus is the alarming infant mortality rate in India. Infant mortality rate is 47 per thousand live births that translates to 12.5 lakh infant deaths per year.

The above challenges present a strong need to develop solutions to address problems of our customers with competitive cost, quality or access benefits. The talk will focus on specific innovative and cost-effective solutions that have been developed to meet the unique and pressing needs of our country and its underserved population thereby resulting in improved clinical and patient outcomes. The talk will also focus on solutions developed for India that can also address global healthcare needs.

Abstract Session II

Distributed generations and microgrids are becoming a common feature in today’s energy sector. They are capable of meeting the demands of local loads and operate in a self sufficient mode. With surplus generation they can export power to the grid. In the case of grid failure leading to an isolated operation of the microgrid, the power balance must exist and hence we need to tinker with the power setpoint of different power sources. The effective will be this setpoint regulation the better will be the microgrid frequency oscillation damping.

The talk will concentrate on this issue of setpoint control which can be achieved by

different optimisation techniques, intelligent techniques. The simulation results will indicate the effectiveness of the approach for damping of frequency oscillation following a load disturbance.

Further, discussion will be made, how to implement the concept of central controller in the microgrid for better resource management and frequency control. It can be proposed that the data at the central controller will be obtained with the help of multi-agent concept (treating each load and source as an agent) through internet using User Datagram Protocol/Internet Protocol (UDP/IP).

Abstract Session II

Today in India, with the ever increasing multiple threats like traditional warfare, political issues, underworld and militant activities, insurgency and terrorism in border areas/urban cities/ public places etc., law enforcement agencies, armed forces and VIPs facing security problems. To get protection against such threats an engineering solution available known as armor technology and this is used to protect individuals or vehicles from high velocity projectiles or bullets. There is always a demand for reliable light weight advanced armor systems, which are not yet completely fulfilled both in the area of personal and vehicle protection. Moreover, existing armor system with the law enforcement agencies, security forces and armed forces, which were developed a few years back and still being used are not fit and heavy to counter the current combat scenarios, which demand protection against more lethal ammunitions, multiple bullet strikes, small fragments from explosives such as hand grenades etc. Though there are a few numbers of manufacturers and suppliers of the armor protection system in the country still we are depending on the technology of some of the advanced countries and importing the advanced materials and armor systems from them. Hence, in Indian context, to meet the current and future requirements a lot of research needs to be carried out on development of new advanced materials and armor design using them.

Coming to overall armor development, some countries developed many types of armor while

some never invented even basic types. After World War II, a lot of research has been carried out and now various kinds of armors are available those vary in shape and size to fit the object to be protected. The steel armor plate being widely used has been quite satisfactory from the protection against projectiles such as .30 and .50 caliber bullets but the weight of steel plate adds greatly to the weight of the armor thereby reduces markedly its mobility and usefulness.

In order to overcome the above limitations of steel, so far a number of other materials such as synthetic high performance fibers, plastics, adhesives and ceramics have been used in constructing armors. Among these, ceramics has gained popularity because of some of its useful properties such as light weight, rigidity, resistance to heat, abrasion and compression etc. Also, the high performance fibers characterized by low density, high tenacity, high modulus, high stain to rupture, resistance to thermal degradation and high impact energy absorption are being increasingly used as soft and flexible fabrics for bullet proof vests for body armor, which provide protection against low and medium energy handgun threats. These fibers also used as reinforcement in the form of polymer matrix composites (PMCs) using thermoset and thermoplastic resin matrices. High performance fibers commonly used in practice today for ballistic protection are S-glass, aramids (e.g. Kevlar, Twaron, Gold shield and Gold flex), high performance polyethylene (e.g. Dyneema, Spectra) etc. These fibers are available in the form of

fabric, prepreg and laminated layers, which used in making of bullet proof vest in body armor. Upon impact of the bullet or projectile, in armor developed using these high performance fibers the energy is absorbed by stretching of the stiff fibers and by dispersing the impact load to surrounding area. Whereas in case of PMCs, the deformation of the fiber is localized and restricted by surrounding resin matrix and energy is absorbed by failure mechanism such as fiber fracture, delamination and shear deformation of the resin matrix.

To provide greater protection against higher velocity ammunitions hard armor has been developed. It includes rigid facing followed by front entrapment and back spall systems. Rigid facing generally includes ceramics and more commonly used are Silicon Carbide, Boron carbide and alumina. In hard armor with ceramic inserts, the kinetic energy of projectile is absorbed and dissipated by blunting the tip of bullet by means of localized shattering of the ceramics. Ceramics used are either in the form of monolithic plates or small pellets/tiles. The disadvantage of using monolithic ceramic plate is that low tensile, low flexible strength and poor fracture toughness, which further reduces multi-hit capability. This is overcome by embedding ceramics in the form of pellets/tiles in a light metal alloy, thermoset or thermoplastic matrices because the propagation of crack is arrested as it travels from the point of incidence to the boundaries of the pellets/tiles and can’t propagate further due to discontinuities in the medium and interspatial matrix between the pellets/tiles. Despite all these advances, there is need for reliable economical and light weight armor systems that have close multi-hit capability, have reduced damaged area, shock and trauma to the object to be protected.

Nowadays, worldwide, research is going on at laboratory level using nanotechnology approach. Superior material characteristics of nanomaterials such as low density, very high hardness, high strength, high strain to failure and high modulus are being utilized to enhance the ballistic performance of armor systems. (e.g. organic fullerenes such as carbon nanotubes and inorganic nanospheres and fullerenes made of compounds such as TiO2, WS2, MoS2, TiS2 and NbS2). It is observed that incorporation of carbon nanotubes into PMCs, metals and ceramics enhance their hardness, fracture toughness and erosion resistance and results in light weight armor with multi-hit capability and improved ballistic properties. Another development courtesy of nanotechnology is ‘liquid body armor’ in Kevlar vests. The key component used in liquid body armor is that shear thickening fluid which composed of nanoparticles of silica in the solution. Under normal conditions the liquid body armor vest act in similar way to water but upon impact it stiffens and provides adequate protection. However, since the nanotechnology approach is at laboratory level more field testing will be required before the armor can be declared as commercial. Moreover, it is also important to realize that as lethal power of the ammunitions grow so the armor technology and vice-versa.

So, to meet the current and future requirements of our country similar kind of research is required like what other advanced countries have at present to develop reliable light weight advanced armor systems. It will be possible with sufficient funds either from government or individual governing body, sophisticated facilities to carry out the research and collaboration between the groups having similar interest in the field.

Abstract Session II

One cannot become an engineer only by education but more so by a decision that one makes and internalizes it. History has demonstrated repeatedly that greatest of the engineers have been the ones who have been driven by passion – passion to invent, passion to simplify, passion to constantly move towards perfection, passion to conquer nature to make life safe, secure, comfortable. There are many educated (un) engineers and there are many who are (un)educated engineers. Edison can be considered as one of the (un)educated engineer who did not study engineering but went on to become one of the greatest engineers of all times. There have been uneducated engineers who have made contributions in all societies and countries towards creating engineering marvels. In the modern context, the capabilities of uneducated engineers can be honed to a great extent by exposing them to relevant formalisms of engineering. On the other hand many who are pursuing formal education do not always

demonstrate an undying passion for engineering and the spirit of engineering seems to fade away as they come closer to completing their formal education. This can be addressed by exposing them to excitement and challenges of being an engineer at an early age, fine tuning the formal engineering curriculum and sustaining their spirit and interest in engineering by providing them stimulating environment through understanding of engineering design, manufacturing and real life problem solving. Efforts have to be made through formal and non-formal channels to promote the spirit of engineering among the students and citizens to create engineers who make an impact through their work on humanity at large. The spirit of engineering is inherent in most people but it either gets buried under the pressure of survival or being successful in measures that the society has defined among which ‘package’ seems to dominate the general youth.

Abstract Session III

While engineering has been defined as “the

creative application of scientific principles to design or develop structures”, research has conventionally been associated with a pure scientific quest. However, a deeper introspection would very often reveal that engineering & research have always maintained a symbiotic relationship, even before any handbooks or theses were written. Human history is rich with examples of when man identified a principle & then applied it to craft some device and at other times, they managed to get something working by trial & error to much later figure out (& explain) the working principles. What remains at the core of either of these drivers is an eternal quest of the human mind to simplify & make life more productive and comfortable. Of course, one should not forget yet another very important factor – the natural curiosity to find out what exists beyond the horizon of existing knowledge & awareness – could that be tapped for further improvement of this planet & the life on it? Certain failures also instigate the next level of research, followed by enunciation of a new engineering principle, practice or discipline. For example, unless the Tacoma Narrows Bridge snapped, it is anybody’s guess as to what else could have led to discoveries & inventions in the principles of aero-mechanics. It took a mammoth Titanic to go into the oblivion of the Atlantic to teach us newer ways of thermo-mechanical treatment of steel rivets! The cultivation of scientific principles through continued research has thus been the natural fuel for coming up with newer principles &applications, thus propelling advances in engineering. A spectacular and inspiring example is embedded in the extensive space research activities. Research & engineering have gone hand-in-glove to not only place man on the moon but also send Voyager-1 close to the periphery of our solar system.

In the wake of all the associated new findings, be it scientific theories or engineering practices, there have been peripheral gains in associated disciplines, viz. aviation, cryogenics etc. A second example is how we have embraced & integrated microwave technology in our daily life. While original intent by NASA was for some space-related research, today a microwave oven is a common household gadget. Closer to pure science & at an atomic scale, Richard Feynman’s years of research led to his iconic lecture at the annual meeting of American Physical Society (1959) at Caltech around “manipulating and controlling things on a small scale”, thus laying the foundation of nanotechnology, which over the past three decades of extensive research, is finding fruition in a range of engineering applications including nanostructured coatings for aviation applications. Advances in nanotechnology has been closely linked to the research progress made in the area of electron microscopy which has equipped us to “see” nanostructures, atomic force microscopy that has helped us “feel” nanostructured surfaces –illustrating the critical role of multi-disciplinary research towards success of current day engineering. The inter-twining of research in provoking engineering innovations is so fundamental that most organizations recognize it & have dedicated R&D houses to advance growth of their P&Ls, viz. General Electric established its R&D center in 1900, which eventually has become& continues to be its powerhouse for 100+ years of spectacular innovation in engineering.

Abstract Session III

The presentation will begin with a brief

overview of Computational Fluid Dynamics (CFD) and its relevance in Engineering and Science. A few case studies will be presented. While some arise from practical applications others are an attempt to understand of certain fundamental issues in fluid mechanics. Most of the applications require large scale computing. To that extent, where-ever possible on parallel computers are used. Flow in the air-intake of a engine of a high speed of an aircraft is very complex. A mixed compression intake for a Mach=3 flow is considered. Viscous effects as well

as boundary layer bleed are modeled. The buzz instability is observed in certain cases. Both, little and big buzz are found. Their frequency is related to the super-harmonics of the intake duct which acts as an open-closed organ pipe. The role of bleed in controlling the buzz oscillations is studied. Some recent work towards understanding the mechanism of swing and reverse-swing of a cricket ball will be briefly discussed. Also shown will be certain new results from investigation of flow past a duck-feather and badminton shuttlecock.

Abstract Session III

Information Fusion has a long history and

has in fact been an integral part of various application domains. For example, an elaborate weather forecast system relies on the evidence provided by diverse sources such as satellites, weather balloons, ground stations, radars etc. in addition to previous temporal information. Automatic target detection/recognition systems use measurements from sensors sensing in different electromagnetic spectra for enhanced accuracy. Ground or flying robots use vision to assess span of an obstacle and infrared/ultrasound sensors for finding range to the obstacle. Most often these sensors provide non-commensurate data that is difficult to fuse.

Like in many other fields of engineering, early research in information fusion, too, was focused largely on military applications and this domain stays the prime focus even today. However, the enormous amount of data being generated from different, and highly disparate, sources in almost every walk of life is increasingly becoming difficult to manage and comprehend, making information fusion absolutely essential. Examples include mining of shopping data for targeted advertising, multiple forms of intelligence for forensic analysis etc. The fused information is expected to provide enhanced situational awareness and provide a sense of confidence in the derived information.

Most process of engineering interest deal with sequential data. It could be time-sequential measurement of target states in a tracking problem or varying stock prices with time for stock market analysis/prediction, or sequence generated by spatial process e.g. bio-sequences. The subdiscipline of information fusion that deals with tracking problems has matured substantially, with sophisticated state-space models handling discrete and continuous, single and multi-variate inputs and outputs with ease, and easily allowing incorporation of prior knowledge in the model.

The field of statistical characterization and modelling of conventional data, and noise, generated by sensors is also reasonably matured. Nontraditional information such as natural language statements, interpretation of a given scene, etc. often requires human intervention. In general, the data could be deterministic or random, precise/imprecise, vague, or uncertain. Additionally, the relationship between data and measurement could be precise or ambiguous. Measurement could be precise or ambiguous to interpret. And a given problem could have combinations of these characteristics.

Various mathematical techniques have evolved to address these ambiguities for example fuzzy logic, neural networks, Dempster-Shafer theory and so on. The difficulty is that almost all of these techniques have no obvious relationship with the matured tracking theory. As a result, it is often

unclear how to develop systematic and integrated solutions to the many real-world challenges.

While fusion of information from multiple sensors/sources is challenging enough, fusion of information originating from multiple targets can cause the challenges tend to multiply. For example, the targets could merge, split, get born or die. Interacting targets could have influence on each other, affecting the measurements. The possibly limited field-of-regard of each sensor that allows only partial observation by each adds to the complexity.

Recently, a unified approach to dealing with these challenges has been proposed that makes use of formal Bayes modelling and recursive Bayes filter in a novel and systematic manner. It provides

techniques for modelling uncertainties due to randomness or ignorance, propagating these uncertainties through time, and extracting estimates of the desired quantities as well as measure of reliability of those estimates that optimally reflect the influence of inherent system uncertainties. These techniques are systematically applied to multitarget information and to unconventional information providing seamless unified statistical approach to multisource-multitarget integration.

This talk will discuss this unified approach along with the systematic multitarget calculus for devising new approximations towards formal and rigorous modelling of multisource-multitarget information fusion problems.

Abstract Session III

The aim of research is to find solutions to real problem statements and achieve breakthrough technologies for improving the quality of life. Applied research is an important subset catering to the needs of industry. The premise of applied research is to identify real problems and attempt solutions on a realistic implementable basis with innovative use of available technology. This however is made difficult by the availability of expertise, difficulties in finding facilities, difficulties in attracting funds and establishing the research in real time. The idea of Research in Engineering is to be encouraged and taken beyond the present structured definitions. Research ability will be the key differentiating factor for academia and industry in the forthcoming era.

The talk “Lab to shop floor: Creating the gateway” will dwell on some of the important issues

in progress of applied research. It also looks into the possibilities of viable applied research adopting new measures. The measures include excluding the idea of associating PhD with research, availability of local funding for private sector, empowering people to be entrepreneurs and associating R&D spend as mandatory for industry and technical institutions. In addition, industrial liaison through MOU, technology incubators in industries, documentation of work done in a common platform, knowledge transfer, research parks, working with international institutions devoted to research, training of human resources are also dealt with. It also accounts for WRI’s experience in addressing these issues by considering case studies of WRI lab’s solutions for its customers.

Abstract Session III

Materials are ubiquitous and their

importance in everyday life is often taken for granted. Materials innovations have been central to a vast majority of technologies since the industrial revolution. The grand challenges of the 21st century - more efficient energy production, greener transportation and buildings, safer food, water and lifestyle – can be met only if development of new materials and processes keeps pace. Traditionally, breakthroughs in materials have been driven mainly by advances in experimental techniques. Despite the large body of empirical approaches to foster materials development, the period between discovery and the functional application of new materials is frequently ten or more years. A major difficulty in expediting new applications stems from the complex interactions taking place within a material over many length and time scales. These interactions, in turn, determine the macroscopic properties of the material and often limit the routes to efficient and cost effective synthesis.

The last several decades have seen an explosion in computational power, with enormous increases in chip density, processor speed and affordable parallel processing. Concomitant with the hardware, many important algorithms have become much more efficient and are capable of exploiting the hardware capabilities to the hilt. Materials research has also been strongly impacted by these advances. A survey of publications in ActaMaterialia in 2011 reveals that 22% of articles included at least one of the two words ‘simulat*’ and

‘comput*’ in the subject, title or abstract. For comparison, this percentage stood at only 10% in 1991. Computational methods have also affected materials design paradigms: new materials development concepts now involve a marriage of traditional and novel experimental techniques, with myriad computational tools spanning various length and time scales. The coming together of experiments and computation is ushering in a renaissance in materials science which promises accelerated discovery and much more rapid deployment of new materials. Modeling and simulation tools are thus finding increasing applications not only in academic materials research, but also in real-world design and optimization of new materials.

In this talk, I will present a review of accelerated materials design concepts which fall under the umbrella of Integrated Computational Materials Engineering, or ICME. I will provide an overview of how ICME enables accelerated optimization of materials, processes, and component design by integrating computations and experiments into a unified archetype. I will also try to highlight some of the successes of the approach via case studies from the literature and based on research in our lab.

Despite its burgeoning potential, ICME is still nascent. Early trials have lead to more failures than successes and significant challenges must be overcome before ICME becomes the materials

design method of choice. I will try to provide some examples, again from research in our lab, where computational materials design concepts fall short. In this context, I will try to review ongoing attempts at overcoming the technical and theoretical challenges facing ICME.

I will conclude my talk by suggesting that the greatest hurdle facing ICME is not technical, but instead cultural: the challenge is one of perceptions. Solutions provided by computational modeling are expected to be nothing less than

perfect. That ICME-based materials design concepts have a greater foothold in industrial R&D labs than in academic or research institutions is telling of two things. First, ICME is industrially viable as a design tool; second, academics have not engaged sufficiently with engineers in converting science-based computational methods to engineering design interfaces. Realizing the promise of ICME will require concerted bridge-building between experimenters and modelers, between scientists and engineers, between disciplines, and between length and time scales.

Abstract Session IV

Conventional ceramics achieve significantly lower strength than the raw material used. This is mainly due to brittle nature of ceramics failure and their high sensitivity to small flaws introduced during fabrication. On the contrary, seashells, which are natural ceramics, behave in a more ductile manner. Their unique brick-mortar architecture makes them tougher and stronger than their constituents. Pearly layers in seashells, also known as nacreous layers, have an order of magnitude higher toughness than most ceramics. Replication of these features of seashells has immediate practical applications; for example, design of lightweight, efficient and cheap armour. A detailed macroscopic

and microscopic investigation is conducted to understand the reasons for this remarkable increase in mechanical properties of seashells. A new nature inspired method is developed in this study mimicking the thin ceramic layers and tough interfaces as in seashells. Green alumina-based ceramic tapes are stacked with screen printed stripes of graphite. During sintering, graphite oxidizes leaving empty channels in the stack. These channels were filled with epoxy afterwards. Flexural testing showed crack deflection at the interfaces and more than two-fold increase in toughness.

Abstract Session IV

Research and innovations in engineering, in the current scenario, have a strong interdisciplinary flavour. Our research group has accordingly been involved in interdisciplinary research that has been cutting across engineering, physical, chemical, as well as biological sciences.

Our research group has contributed towards unveiling several new facets of fluid flow over disparate physical scales, especially related to microfluidics, nanofluidics, and phase change phenomenon. Our investigations have revealed that a rough surface, under specially designed circumstances, may actually help in transmitting a fluid flow, instead of creating additional resistances, contrary to common scientific intuitions. Importantly, the scope of our research has not been restricted with the development of scientific insight alone; we have attempted to advance that understanding further to develop new-

generation engineering devices that hold the potential of revolutionizing biotechnology and low-cost biomedical diagnostics, especially in the context and relevance of rural India.

With the aid of his fundamental scientific discoveries, we have designed new generation painless microneedles for blood glucose monitoring and insulin delivery, non-mechanical valves for controlling fluid motion with the aid of light, traction-force microscopy for capturing the cancer cell dynamics in micro-confinements (this has unveiled a new paradigm related to the physical mechanism of cancer progression), CD-based micro-devices for biomedical analysis (inexpensive and rapid pathological diagnostics with a portable kit), rapid DNA hybridization protocols, and several other innovative miniaturized devices and systems for bio-medical, bio-technological, and chip cooling applications.

Abstract Session IV

Innovation is defined as finding new ways

of creating value1. As innovation in engineering is emerging as the clear differentiator between products and services in the market, organizations are placing increasing importance in tapping new ideas and turning them into breakthrough innovations suited to their business products, or in some disruptive cases, adding a new line of business to their portfolio. Innovation tools such as TRIZ (Russian acronym for Theory of Inventive Problem Solving) are being increasingly used as methods to trigger innovative thinking outside the box.

The other trend coming out of these exercises is the realization that innovation lies at the overlap of disciplines, thereby taking the realm of cross-collaboration to new heights. This talk is aimed at highlighting innovations happening at the very exciting John F Welch Technology Center at GE, India, with specific examples panning across different GE businesses. The talk is also going to illustrate examples of the use of innovation tools towards sparking the next big innovations in engineering.

Abstract Session IV

Innovative research in required in the area

of Internal Combustion (IC) engines for utilization of alternative fuels and engine emission control. At ERL, IIT Kanpur, a very innovative technique has been developed along with a simple and cheap hardware for using straight vegetable oils in stationary diesel engines, which are typically used in decentralized power generation sector and agricultural sector.

Another innovation from ERL, IIT Kanpur is related to "laser ignition" of combustible mixtures in an IC Engine. This concept has been demonstrated experimentally at ERL, IITK, where the engine can be ignited by using a laser fired spark plug instead of an electrical spark plug. This ensures combustion of leaner mixtures of fuel and air, which leads to 70% reduction in NOx emissions. These experiments have been successfully carried out on CNG-air mixtures and the technology has been successfully demonstrated on a prototype engine developed at ERL, IIT Kanpur. This technology has paved way for development of next generation hydrogen fuelled engine because this technology has potential of eliminating some of the serious outstanding and unresolved issues related to development of hydrogen fuelled engines.

Homogeneous Charge Compression Ignition (HCCI) technology has significant advantages over the conventional engine concept such as reduction in NOx and PM simultaneously, without the Soot-NOx

paradox and also promises significant improvement in fuel economy. Diesel like fuels (such as diesel and biodiesel), which have poor evaporation characteristics as well as gasoline like fuels (such as alcohols, gasoline), which have excellent evaporation characteristics, have been used successfully in HCCI engines in ERL, IITK. Suitable hardware for preparing partially homogeneous mixtures of diesel-air has been developed at ERL. ERL has also successfully developed closed loop control method for achieving HCCI combustion, which was one of the main obstacles in reaping the fruits of this promising technology.

It is very important to develop fundamental understanding about the spatial changes in combustion characteristics inside an engine combustion chamber in order to optimize the combustion, which can potentially make it an efficient alternative for mineral diesel. Endoscopic visualization technique is one of the possible innovative techniques to experimentally investigate the variation in spatial combustion characteristics inside the engine combustion chamber under firing conditions. Engine endoscopy technique is implemented in a single cylinder diesel engine at ERL. Experiments are conducted for mineral diesel, biodiesel and their blends (B20, B50) at different engine load conditions. Combustion images were captured after every 0.5 crank angle degrees and these were further analyzed using image processing methods/ programs to determine various

combustion related parameters such as start of combustion, spatial distribution of soot and spatial flame temperature distribution. It was also found that results obtained from endoscopic technique matches well with the results obtained from conventional techniques for comparing the start of combustion, soot concentration and flame temperature. It was observed that luminosity of

flame in combustion images decrease as the oxygen content in the fuel increases (i.e. increasing biodiesel content). In summary, endoscopy is a great technique to fundamentally understand the combustion in the engine combustion chamber and the effect of changing fuel composition on the combustion.

Abstract Session IV

There are many biomechanical challenges that a female insect must meet to successfully oviposit, or lay eggs, to ensure her evolutionary success. These begin with the selection of a suitable substrate through which the ovipositor tool must penetrate and cut without itself buckling or fracturing. The second phase corresponds to steering and manipulating the ovipositor inside the substrate to deliver eggs at desired locations. Finally, the insect must retract the ovipositor fast without undergoing elastic recoil to avoid possible predation and repeat this process multiple times during her lifetime. From a materials perspective, insect oviposition is a fascinating problem and poses many questions. Specifically, are there specific mechanisms that an insect uses to drill through hard substrates without itself buckling or fracturing? What are the structure-property relationships in the ovipositor material? Do these correlate with presence of sensing cells to aid the insect’s ability to detect deformations and chemicals? These are some of the questions we address with a model system consisting of a fig wasp - fig substrate system and using an integrative approach to explore the biomechanics of substrate boring by insects. To characterize the structure of fig wasp ovipositors, we use scanning electron microscopy with detector for energy dispersive X-ray spectroscopy to quantify the presence of different elements in the insect material.

Unlike the working of hypodermic needles, our results show that wasp ovipositors consist of three valves interconnected by rail guides to facilitate substrate boring. Different sensillae on the ovipositor tip aid the insect in detection of signals from chemicals and those due to mechanical deformations

during oviposition. Ability of the ovipositor tip to manoeuvre and steer within the substrate is achieved through a combination of flexible and curved ovipositor parts which may serve to be highly beneficial for multiple egg depositions within the same bored hole. Albeit absent from regions far removed from the drilling ends, ovipositor tips of parasitoid insects have jagged serrations rich in zinc. Based on these results we hypothesize that presence of zinc in ovipositor tips serve to increase material hardness. To quantify microscale material properties, we use an atomic force microscope. Our results show that reduced modulus in tip serrations is significantly higher as compared to remote regions. Together, these data suggest use of novel methods by insects to increase material hardness and reduce wear through incorporation of zinc in the material. Finally, videography of ovipositing insects shows that the slender and long ovipositor structures undergo buckling during drilling. Using Euler buckling equations, in conjunction with the force microscopy results, we calculate forces generated by insects during oviposition. Reverse engineering methods have recently been proposed based on biomimetic designs to design miniature drilling bits for space applications and for design of surgical tools with flexible cables, embedded with sensors, to guide probes. We hope these data will also be useful to characterize interactions between insects and plants in correlating the choice of substrates used by insects for oviposition.

Abstract Panelist

The United Nations Development Programme's Human Development Report in 2011 rated and evaluated 187 countries based on the HDI (Human Development Index), a comparative measure of life expectancy, literacy, education, standards of living, and quality of life for countries worldwide. India was ranked #134 out of 187 countries, i.e. in the bottom 1/3rd. When we consider the subject of engineering in national development, we have to understand the perspective of the role of engineers and engineering in driving improvements for the nation along the HDI’s three dimensions:

• A long and healthy life: Life expectancy at birth

• Education index: Mean years of schooling and Expected years of schooling

• A decent standard of living: Gross National Income per capita

Taking the first dimension of HDI, when we look at improvements in life expectancy, we need to consider what has been achieved so far in recent times with respect to engineering in healthcare and what the associated trends are: e.g. convergence of consumer products with healthcare products, miniaturization of medical devices, role of information technology and role of RFID. In addition, we need to consider the challenges for technology in healthcare and how we can overcome those challenges for diagnosis,

detection and treatment of diseases – these challenges span across:

1. enabling a multidisciplinary approach across bio-technology, biology, medicine and medical devices;

2. leveraging of new technologies such as nanotechnology in healthcare;

3. leveraging of information technology and mobile technology in healthcare;

4. bio-medical waste management.

Taking the second dimension of HDI, when we look at improvements in education, we need to consider how best we can utilize technology and engineering talent:

1. How do we use PCs / laptops / handheld devices and E-learning towards improving access to education for all as well as improving quality of education provided including the cost-productivity factor?

2. How do we leverage technology for improving quality of teaching through peer collaboration

among teachers, online training and sharing of digital content / best practices?

3. How do we enable innovations across multiple engineering-related areas such as biometrics

(for attendance), renewable energy (for power) and water / sanitation to solve some of the most critical issues in education?

Taking the third dimension of HDI, when we look at improvements in standard of living, the obvious role of engineering comes to the fore in the specific focus areas of faster, sustainable and more inclusive growth i.e. driving higher net incomes for all, working towards lower incidence of poverty, enabling better opportunities for both wage employment and livelihoods, and improving provision of basic amenities like water, electricity, roads, sanitation and housing.

1. The Aadhaar initiative is utilizing biometric technology and information technology to deliver a unique personal identity to millions of Indians. What are the issues and challenges of engineers in coming up with solutions leveraging the Aadhaar UID for enabling financial inclusion and transparent access to funds for the poor people across the country?

2. How can we use Information Technology to move jobs and livelihoods in the services sector to the villages and rural areas where they are needed the most?

3. How do we engineer technology innovations for improvements in agriculture such as irrigation and renewable energy powered equipment?

4. How do we engineer improvements in renewable energy products – from solar lighting systems to bio-gas digesters to efficient cookstoves – to deliver the much needed benefits to the poorest of the poor in rural areas and help them improve their net incomes? And at the same time, utilize the engineering talent in the renewable energy sector to ensure sustainable growth of the large cities and towns?

5. The Gartner Group published its research and analysis in March 2012 that projected the India mobile subscriber base to reach 696 million connections in 2012, up 9% from 638 million in 2011. In addition, the Gartner Group analysis projected that India’s mobile subscribers would exceed 900 million and achieve 72% penetration by 2016, up from the current 51% mobile phone penetration. Mobiles have become the most ubiquitous modern technology in India: in a lot of areas, more people have access to a mobile phone than to electricity, or even clean water. How do we learn and engineer technology innovations to facilitate similar phenomenal access to electricity and clean water, etc.?

6. What are the issues, challenges and potential solutions to come up with cutting edge technology and deliver the very latest engineering solutions that provide the greatest value for money and the greatest material impact in infrastructure sectors such as roads, shipping, air, power / energy and natural resource management – water, land and forests.

7. How do we provide and implement technology solutions for overall governance in the country? Can biometrics and information technology catalyze better governance, ethical governance and transparency?

To achieve success, engineers need to understand and discover their passions, nurture their natural intellectual curiosity across multiple disciplines – engineering as well as non-engineering disciplines, drive a convergence of innovations across multiple disciplines, and leverage their training and collective experiences during implementation.

Abstract Poster

 

During service, in addition to the magnitude and nature of the load (tensile/compressive), loading rate that the engineering components experience also plays a major role in deciding the components’ life. Therefore understanding the loading rate dependant mechanical behavior is of utmost importance to the scientists/engineers while designing the components for diverse engineering applications. Testing techniques are readily available to understand the loading rate dependent deformation behavior of bulk engineering components and the details are well documented in ASTM (American Society for Testing and Materials) standards. However, the problem arises, when the sufficient material is not available to perform the mechanical testing in the traditional ways as per ASTM standards. In that scenario, a novel approach can be adopted using depth sensing nano mechanical testing. In this, material behavior is probed at very small volumes typically at nano

meter length scales at various depths and loading rates. Strain Rate Sensitivity (SRS) or Loading Rate Sensitivity (LRS) can be estimated that would aid in designing engineering components or subsequently understanding the material behavior during service at miniaturized dimensions for a better tomorrow. In the current study loading rate dependent mechanical behavior of different nanostructured two phase binary alloys and nanostructured multi-component alloys was investigated using this method in a nanomechanical testing machine and their loading rate behavior at different loads (contact depths) at room temperature would be discussed. The outcome of this work would assist the scientific/engineering community in better understanding the mechanics in Micro Electro Mechanical Systems (MEMS), Nano Electro Mechanical Systems (NEMS) and also the contact mechanics of electronic circuits at nano scale.

Abstract Poster

The dimensional change occurring in magnetic materials under the influence of external magnetic field is called magnetostriction. This property is exploited for a variety of technological applications such as actuators, acoustic transducers, etc. The characteristics required for such transducer/ actuators are met in a classic material called (Tb,Dy)Fe2, which is an intermetallic compound with easy magnetization direction (EMD) along <111>. Therefore, if these materials are grown with preferred grain orientation along the easy direction of magnetization, it results in enhancing the coupling co-efficient (k33) to better than 0.7. The development of this material, therefore critically depends on the alloy composition, grain orientation and the overall microstructural features.

Amongst, several directional solidification techniques, zone melting was adopted for growing rods of smaller diameter (<10 mm) and modified Bridgman technique was adopted for obtaining textured rods of larger diameter (10-35 mm). A comprehensive understanding on evolution of texture and microstructure has been developed by several experiments followed by characterization of microstructure and texture. In order to pursue such involved experimentation, a state-of-the-art solidification facility has been designed and indigenously developed at DMRL. The understanding on complex interplay between texture-microstructure-composition and process

parameters led to development of giant magnetostrictive (Tb,Dy)Fe2 material that exhibits a large magnetostriction of 1600 microstrains at a field of 3 kOe. The slope of the linear region of magnetostriction vs. applied magnetic field curve (static strain co-efficient) is found to be very sharp, which is on par or even better than the values reported by other laboratories world over.

Subsequent to this path breaking success in material development, the laboratory has undertaken the task of development of an ultrasonic transducer for underwater surveillance to establish technological potential of the material. The programme is being pursued in collaboration with NPOL, Kochi. The transducer developed with magnetostrictive rods developed at DMRL is found to produce sound wave of resonance frequency 1.65 kHz with transmitting power response (TPR) of 168 dB reμPa/W. Development of such low frequency high power transducer has shown promise for its utility in developing a portable device with increased detection range for underwater survilience. Further, the successful translation of material to device indicates the potential use of this material for other applications such as actuators.

As a spin off from this developmental activity, several scientific understandings have evolved, such as, ternary modification of phase equilibria of Tb-Dy-Fe, detrimental role of

(Tb,Dy)Fe3 phase either as pro-peritectic phase or as Widmanstatten precipitate, the intimate relation of processing and microstructure on magnetic properties such as magnetostriction, magnetization, coercivity, anisotropy and hyperfine field. Concurrently, research on the alloy modification by addition of Nb, Zr, B and Pr were also carried out.

Recently, research activity on the emerging magnetostrictive Fe-Ga alloy has been

initiated to overcome the limitations of Tb0.3Dy0.7Fe2 material such as brittleness, low static strain co-efficient and high reactivity of rare earths. Therefore, a series of alloys Fe100-

xGax (17 ≤ x ≤ 30) were subjected to several thermal treatment conditions to establish the processing condition to achieve desired microstructure required for improved magnetostrictive property.

Abstract Poster

The Nondestructive Testing (NDT) industry is on the cusp of entering the information age. Industry trends such as digitization of equipment, greater use of automation and rapid development of new techniques point towards greater use of information technology (IT). With increasing sophistication of NDT techniques and equipment - software is becoming the focus of development. With almost exponential rise in test information generated, the creation of software tools and platforms to cope with growing needs and demand is assuming greater importance among NDT users. The need of the hour is to make the data user-friendly. Everyone wants to deal with images. There are many engineers, who look at the test signals and know what they mean, but for those who aren’t deeply trained [in NDT] and expert, you need pictures. The more visual the results, the more expanded will be the use of NDT.

Growth of software is driven by need to improve testing efficiency and reproducibility and to manage and store increasing amounts of data. The software essentially needs to acquire the data from an instrument, process the data with application specific tools, support decision making/make decisions, and then present or store/archive. Most current software systems have been developed for proprietary hardware and hence there is no standard platform that operators can adopt. Further the software needs to be future proof, i.e. to be adaptable to newer applications, a problem that much of the current software faces. For example, with growing

popularity of new techniques such as Phased, Array, most equipment manufacturers are faced with the challenge of having to create new software. Allied to this challenge is the need for the software to be able to use standard data formats such as DICONDE and DICOM. This will ensure that the data can be stored and reused without need for conversion and that data from other sources such as pipeline databases can be used in this platform.

The software must offer the ability to interchange and communicate between two (or more) different test systems. The challenge of Software lies in multimodality fusion. Today, we can put the results of X-ray, ultrasonic and eddy current tests side by side, but the person is the “multimode,” serving as a reference point for all three and combining the results. The challenge is to merge the results that the person is no longer the multimode?” We need to communicate all that data in an intuitive fashion. This therefore is one of the keys to creating a standard platform. Kovid NDT Software from Lucid Software Limited offers advanced NDT image analysis and data management for the different techniques such as RT (Computed Radiography, Digital Radiography), Ultrasound, and Visual Testing. It provides the complete solution starting from acquiring the data from the equipment, visualization, analysis of the data using advanced image analysis filters and data management.

Abstract Poster

Oxide dispersion strengthened (ODS) materials are considered for high temperature and high performance applications due to high strength and creep resistance. They find application not only as materials for use in gas turbines but also for nuclear reactors. The performance of ODS materials depends on the composition, stability, concentration, size, spacing and distribution of dispersoids in the matrix. Yttria, being hard and stable at high temperatures, is the most widely used dispersoid in steels and super alloys. Significant development work was done to improve the high temperature capability of Fe-Cr-W-Ta steels extensively used in thermal and nuclear power generation units by incorporating nanometer size Y2O3 particles. Recent developments indicate that the presence of Ti in steels improves the strength even further.

Yttria dispersed (≈0.3 wt%) ferritic-martensitic steels (Fe-9Cr-0.1C-2W-0.2Ti) exhibit better mechanical behavior than the base material up to 700°C. The superior properties were explained to be due to refinement of Y2O3 (30-50 nm) to even finer size (3-5 nm) and coherent complex oxides (Y2Ti2O7/Y2TiO5) produced

through an interaction with Ti as well as excess oxygen. These ODS ferritic steels with bcc structure possess ability to suppress void swelling better than the austenitic steels with fcc structure. But, ferritic ODS steels have been reported to possess a little anisotropy in mechanical properties. The Y2O3 dispersed martenstic steel exhibits nearly isotropic mechanical properties after final heat treatment producing equiaxed grain structure. But the application is limited to 650-700°C because of poor oxidation resistance compared to 12%Cr ODS ferritic steels.

The dispersion of Y2O3 in ferritic/ martenstic steels can be achieved by mechanical alloying and the consolidation of these ODS steels involve processes like degassing, canning and hot extrusion. The parameters used for these processes including mechanical alloying play a significant role in the final properties like density, hardness and strength of the consolidated ODS steels. This paper discusses the effect of these process parameters on the final properties of the ODS steels.

Abstract Poster

The United Nations' Intergovernmental Panel on Climate Change (IPCC) report, based on the work of some 2,500 scientists in more than 130 countries, concluded in Feb 2007 that it is very likely that human development has caused all or most of the current planetary ‘global’ warming. A follow-up report by the IPCC released in April 2007 warned that global warming could lead to large-scale food and water shortages and have catastrophic effects on wildlife. Such reports have led the scientific community to question the direction of scientific and technological development. This report has fueled the already strong environmental movement among social scientists who have been arguing for more appropriate technologies that enable alternative economic and social development paradigms.

The UNDP has been publishing the human development report and human development index (HDI), which looks at more holistic parameters of economic development other than GDP. In June this year, at the UN Conference on Sustainable Development, the United Nations Development Programme (UNDP) presented the conceptual groundwork for a future “Sustainable Human Development Index,” which would recognize the costs of today’s development to future generations. HDI measurements published in the past have established the diminishing marginal returns (in HDI)of energy intensive growth after a threshold of 4000 kwh per capita electricity consumption.

While electricity consumption per capita is well below world average in India, the per capita energy consumption crossed the 4000kwh threshold as per the latest report of the Central Statistics Office. There has been an exponential increase in conventional energy use since 1970. As per the US Energy Information Administration 26% energy consumed in India is from renewable sources (including bagasse), albeit in the unorganized sector and several opportunities exist for better end-use technologies.

On the supply side, a comparison of life-cycle emissions shows that renewables & nuclear are cleaner fuels. For nuclear energy, technology transfer is crucial but governments all over the world including in India have hit the pause button after looking at the liabilities from the tsunami incident in Japan. India does have shale deposits across the Gangetic plain, Assam, Gujarat, Rajasthan, Gondwana & Cambay basin, however here again technology transfer is crucial and we will have to study the future impact of the Reliance-BP deal on exploration. Government of India estimates of renewable energy (all renewable energy types) potential is around 89.7 GW. The Planning Commission has also set a demand side management target as projected electrical energy saving potential at the end of 12th Five Year Plan is 44.85 Billion KwH on the demand side with an additional energy saving equivalent of 21.3 million tonnes oil equivalent in the industrial sector.

Future ‘green’ and sustainable possibilities in India include innovations such as bottoms-up community efforts to completely transform energy consumption patterns in communities like Auroville; Innovative top-down government initiatives such as the Gujarat Narmada canal-top solar project and finally public-private partnership projects such as Delhi Metro’s innovative projects registered with the UN Framework Convention on Climate Change for use of the CDM (Clean Development Mechanism).

Abstract Poster

The Brahmaputra River, originating from Tibetan plateau, drains high flow and sediment load in its sand-bed braided channels. The width of the channel varies from 1.2 km to 18.5 km. The temporal variation of the flow in the river is remarkably high with its average of 18,000 m3/s; ranging between the annual peak flow (40,000 m3/s) and lowest flow (3,000 m3/s). In every monsoon season, long period flood waves (10-20 days) propagate through the river. Using the advanced river survey instruments, 3-dimensional velocity vectors and suspended sediment concentration were measured in river reaches. Results show that there are multiple velocity core zones in a single curved channel and the suspended sediment concentration follows fairly uniform distribution due to large scale turbulences. In the spatial scale, large-scale turbulence structures were observed at the intermixing of low sediment channel and high sediment channel. These complex hydrodynamic characteristics alter the bed forms, shifting the maximum velocity line and shifting the confluence zones of the channels. With the help of multidate microwave satellite imagery, we found

that the spatial distribution of the turbulence zones is complex and closely interact with depositional zones and bank erosion processes.

In order to characterize the bank soils, a series of submerged jet apparatus experiments were conducted in the bank layers of the Brahmaputra river. The fine soils in the banks have one-order variation in soil erodibility. A two-dimensional hydrodynamic and sediment transport model was formulated and developed, considering the spatial variation of the soil erodibility. The performance of the model was evaluated to predict the bank erosion rate for a number of the braided reaches in the Brahmaputra river. The model prediction has well agreement with the bank erosion rate obtained from multidate satellite imagery. In short, a series of multi-scale observations from in-situ, satellite imagery and the mathematical modeling simulations can help incharacterizing large scale turbulences, sediment mixing, sediment transport processes, and bank erosion processes in the complex braided river like the Brahmaputra.
