The ES Could Probably Know More: But Man Would Not Make Better Business Decisions

Zoltan Baracskai1 , Viktor Dorfler2 , Jolan Velencei3 1Doctus, Budapest, Hungary2Strathclyde University, Management Science Department, Glasgow, United Kingdom3Budapest University of Technology and Economics, Management and Corporate EconoDepartment, Budapest, Hungary

We know for a long time that expert system (ES) must not know in a different way than howman knows. We would not expect men to adapt their thinking processes to the machine,would we? Evolution would not let peoples' minds adopt criteria weighting or fuzzy logic.This is why we developed our Doctus knowledge-based expert system based on symboliclogic that is the most understandable artificial knowledge representation to the decisiontaker. However, this is all history now...

The Description of Biological Growth Using B-splines Hermite Interpolation

Donatella GiulianiDepartment of Mathematics, University of Milan, Italy

The fibrous structure of a biological body is very often well recognizable and remains totestify the essential aspects of growth. The biological growth occurs on surface or along anedge, named growth surface or growth curve respectively (Skalak R., 1982, 1996).The aim of this work is the analysis of a biological bi-dimensional structure in order to studythe shape in development through the identification of the discontinuity points of thetangent vector of the growth curve, from now on named principal growth points. The studyof the growth curve is realized by polynomial piecewise interpolation. The polynomialpiecewise interpolation is not restricted to interpolation of data points, including derivativedata at the principal growth points. This leads to the B-splines Hermite interpolation scheme.The growing form results strongly characterized by the tangent vectors at the principalgrowth points, whereas variations of data points may produce local changes of shape.

The History and Philosophy of Autonomous Artificial Intelligence

Amy R. Hudson1 , [email protected], Larry H. Reeker, [email protected] Institute of Standards and Technology, Gaithersburg, MD, USA1 and University of Maryland College Park

About thirty-six years ago, a paper authored by B. Chandrasekaran and the second author ofthis paper was delivered at a workshop on Possibilities and Limitations of ArtificialIntelligence, sponsored by the National Science Foundation and organized by the IESystems, Man, and Cybernetics Society. It was called Artificial Intelligence - A case forAgnosticism. It contained a dialogue between the Agnostic, who argues for a middle-ground between two other characters: (1) a True Believer who argues that truly thinkingmachines are just around the corner, and (2) an Infidel who goes out of his way to findsome argument that says a really intelligent system would never work. Agnosticism was areasonable stance in those days and was the way most (of the few) computer scientistsworking in the field thought.

Finding Out More About a Little Known Children's Science Textbook Author:

A Case Study of Mary Amelia Swift, Illustrating the Power and Pitfalls of the Internet

Dr Bill PalmerIndependent scholar, Australia

Mary Amelia Swift has left two slim volumes that introduced American children in the early19th Century to the study of science. Her dates of birth and death are uncertain and differentsources contradict each other concerning a number of details of her life. Nonetheless usingthe power of the internet and some rare texts, much information about her life can becollated for the first time. Two textbooks are distinctly religious in tone and were widelyused in America over a period of fifty years. They were also used in translations in theBurmese Christian missions but even more surprisingly evidence can be found that these books were used in Japan during Japan's 19th Century efforts to westernise its educationsystem.

Automated Parking System for a Truck and Trailer

D. Novak, D. Dovan, R. Grebenek and S. Oblak, Slovenia

Automated parking systems are becoming increasingly important in the control community.The automotive industry is promoting efficient systems to assist drivers with reverse andparallel parking, with a fully automated parking system as the ultimate goal. The problem is

even more challenging for trucks with trailers due to the interaction between the truck andthe trailer. When reversing, the truck and trailer can be modeled as a nonholonomicnonlinear system with state and input saturations. If the angle between the truck and thetrailer reaches a certain threshold, the so-called jackknife phenomenon occurs and the anglecontinues to increase regardless of the turning angle of the truck. Even experienced truckdrivers try to avoid turning the truck while reversing it. In our project, we tried to maketruck reverse and parallel parking easier for drivers by designing an automated controlsystem capable of parking the truck and trailer by itself. Such systems already exist for cars, but not for trucks.

Values Education Acquired, Not Learnt: A Foundation for Sustainability Masoud Aliakbar Golkar, [email protected]. Toosi University of Technology, Seyed-Khandan, P. O. Box 16315-1355, Tehran, Iran

The paper emphasizes that integrating values education is crucial for the sustainabilityagenda. It is anticipated that the acquisition of moral values by students will help produceeco-citizens who will be culturally involved in the practice of sustainability. The mainmessage of this paper is: "Values are acquired, not learnt" and the role of the educator is tohelp develop/implant values, related to the social, economic and environmental facets ofsustainability, in the hearts of students. The paper outlines a model of the teaching-learningprocesses, which complies with this concept. It is imperative that students first understandwhy a certain value should be acquired before actually learning about its meaning. Valueshave to be integrated and taught in a manner which enables students to intrinsically acquirethem. The mere knowledge of values cannot ensure that people endorse them in theiractions, which is fundamental in achieving sustainability.

A Survey of Split Data Caches

Miroslav GasicDepartment of Computer Science, University of Belgrade, Belgrade, Serbia

In the last decades the speed gap between the memory and processors has been steadilyincreasing. Because of this, a lot of effort was invested in hiding memory latency. One of the

ways to reduce memory latency is usage of cache memories. Today cache is usuallyorganized as a multiple level hierarchy. The first-level hierarchy is split into twoindependent organizations one for storing instructions and another for storing data. In theconventional cache, first level data cache uses only a single cache to store data. However, thisis not optimal because data exhibit different types of locality. In this paper we willconcentrate on the work done by researchers to design split data cache, which will improveperformance/complexity ratio of data cache. We will make a chronological survey of themost noticeable designs, which made the greatest influence in this area. We hope that in thisway reader will get the whole picture of the problem and the work done, by others, to solveit. Firstly will be given criteria by which designs can be classified. After that, shortdescription of every chosen design will be made. New ideas and differences compared to

previous designs will be specially emphasized, in this way at least partially it can be seenhow did researchers think and what are the key points of the problem in there opinion.Starting point, of our chronology, will be victim cache purposed in 1990. We will continuewith the dual scheme, the first design exploiting temporal and spatial locality, and othersfollowing them Results of performance made by researchers will also be represented, so itcan be seen what concrete results each design makes.

No More Hops: Towards a Linearly Scalable Application Infrastructure

Owen Taylor, Sr Director for Worldwide Technical Communications, GigaSpaces Technologies,

Tier-based architectures are essentially database-based and this causes scalability issues bothdirectly and indirectly. Due to the heavy reliance on the database as the sole reliable storagemechanism, traditional architectures include mapping effort (ORM) as well as network hopsto and from the DB which both cause increased latency. Additionally, traditional systemsoften utilize messaging as a stop-gap measure to defer processing that could be bestperformed immediately. As the demand on the number and size of requests supported bythe application grows, the pain caused by these two design decisions grows. We will discussan alternate architecture utilizing Transparent Partitioning and Colocation. This allows thecreation of a "processing unit", a single process that addresses reliability, messaging, andprocessing without involving network hops within the critical transaction of the application.Examples will show how this pattern can be leveraged to increase throughput and reducelatency for Java, .NET and even Excel applications.

Going Out of Bounds: Building RIAs for the Web and the Desktop

James Ward, Technical Evangelist for Flex, Adobe, USA

Web 2.0 is more than a social networking phenomenon. It's a paradigm shift in applicationdevelopment that's removing previous constraints and exposing new paths to meet userexpectations for richer and more engaging digital experiences on devices and platforms of all

types. A number of technologies such as Ajax, Ruby on Rails and Flex are emerging as thefavorites in the developer's toolbox, taking the Web to these new levels of user engagement.But where to next? Rich Internet Applications (RIAs) that break out from the traditionalpage-based Web paradigm and that currently run in the Web browser will soon run on thedesktop, both on and offline, with the ability to access local data and use Web services topresent an integrated and unique user experience. This session will use informative demosand live coding to teach best practices and techniques. You will learn how to leverage yourexisting Web development skills with Flex, Ajax, Ruby on Rails or JavaScript to build anddeploy applications that bridge the Web and Desktop. You will learn how tools like AdobeAIR and the Open Source Flex SDK simplify how your applications are created, deployed,and experienced.

Domain Specific Reference Models for Event Patterns for

Faster Developing of Business Activity Monitoring Applications

Rainer v. Ammon1 , [email protected],Christian Silberbauer1 , [email protected],Christian Wolff 2 , [email protected],1Centrum fr Informations-Technologie Transfer GmbH, D-93051 Regensburg, Germany2 Media Computing, University of Regensburg, D-93040 Regensburg, Germany

Business Process Management (BPM) and real-time Business Activity Monitoring (BAM) arenewly discussed as the preconditions for a so-called predictive business and thecompetitiveness of enterprises in the future. Complex event processing (CEP) is an emergingtechnology that shall be the basis in order to achieve actionable, situational knowledge fromdistributed message-based systems, databases and applications in real-time or near real-time.Detecting event patterns in an event cloud or in one or more event streams is a basic idea ofthe CEP technology. If low level events without any semantics occur in specificcombinations, a complex event on a higher business level can be derived of them as well asof historical events stored in databases. First attempts of setting up CEP applications haveshown that the potential adopters have major problems to define the needed event patterns.This is a reason why future CEP applications will delay to be set up. Therefore the

availability of domain specific reference models for event patterns is needed. In the projectDoReMoPat, a catalogue of reference models for selected domains like automotive, finance,logistics, telco are developed and implemented as customizable prototypes. A meta model isdefined for faster developing reference models for other domains. Reference models forevent patterns can dramatically reduce time and costs as well as improve the quality ofBPM/BAM projects.

The Heart and Its Powers of Ten:

Towards a Unified Multiscale Biological Model on Anyscale Machines

Joanna Leng1 , Lee Margetts1 , Sanjay Kharche2 , Henggui Zhang21 Manchester Computing, University of Manchester, Manchester, M13 9PL, UK 2School of Physics and Astronomy, University of Manchester, Manchester, M60 1QD, UK

The goal of the authors is to contribute to research in heart modeling in a way that issustainable. This is a review paper in which the authors stand back and consider how thisgoal can be best achieved and identifies and categorizes the challenges that researchers inthis field face. Similar issues exist not only in other areas of biological simulation but in manycomputational science communities where there is a strong element of cross-disciplinarystudy within the discipline particularly between the computational and experimental orobservational communities. The Heart like all biological systems has many levels of detail.This complexity is the root cause of difficulty in the efficient development and execution ofmeaningful simulations. In considering such problems it is important to have a sense ofscale. The intelligent use of scale allows models of biological systems to be adapted to thecomputational resources and tailored to answer the important scientific research questions.Biological modeling requires significant compute resources. Judging from the current levelof progress made in Heart simulation, the authors believe that Petascale computing (orindeed any large scale computing) will bring significant advances in the science only oncethe significant challenges in building simulation environments have been met.

Was there "Women's Republic of Letters"?

Violetta Trofimova, Institute of Foreign Languages, St. Petersburg, Russia

This is a revised version of my paper at the previous Bled conference Were There Nets

Before the Net? The Republic of Letters and womens participation in it. I analyze thenetwork of women intellectuals gathered around Dutch scholar Anna Maria van Schurman. Ipay special attention to the dynamic of this structure which existed around the middle of theXVIIth century, transgressing religious and political borders. I also analyze personalrelationships between Schurman and her correspondents, especially her life-long friendshipwith Descartes disciple and correspondent Princess Elizabeth of Bohemia.

Women's Writing, Salon Culture and Women's Networks in Seventeenth-century Paris


The idea of a network is mostly a twentieth-century phenomenon, but network-likestructures appeared in different spheres long before that. A good example of a network-likestructure, which, most probably, did not contemplate itself as a network, was the so-calledRepublic of Letters a community of the European intellectuals, which transgressed social,political and religious borders and stimulated a lot the scientific revolution in the XVIth-XVIIth centuries. This paper seeks to analyze the role of the most important human centersof this network and to expose the process of accumulating intellectuals among these centers.The latter ones are Maren Mercenne from France, Samuel Hartlib and Jan Amos Comenius,originally from the Eastern Europe, but living in England and Holland respectively.

New Paradigm of Circularity in IEEE 802.11 Based MANETs to Improve Bandwidth

Utilization

S. J. Prasanna, Hughes Systique Corporation

MANET is characterized by highly changing network topologies and connectivities. Due tosuch highly dynamic scenarios, the conventional IEEE 802.11 MAC protocol has variousshortcomings with regard to MANETs. The RTS/CTS access scheme, designed to reduce thenumber of collisions in an IEEE 802.11 network, is known to exhibit problems due to Deafnodes, the imbalance between the interference range and the communication range of thenodes, and scenarios in which nodes are unnecessarily silenced, thus preventing paralleltransmissions to take place. We present an approach for enhancing the performance of theIEEE 802.11 MAC protocol by introducing a new paradigm of Circularity for selectively

discarding, delaying or extending the circularity satisfied RTS, CTS or DIFS to allow certainparallel transmissions to proceed and obviate some ACK/DATA collisions which is one ofthe major issue due to the formation of Deaf nodes to enable MANETs. We implemented thecircularity approach in ns-2 simulator. Through a series of experiments, we show that thecircularity approach provides a significant improvement in the throughput and contributesto a reduction of the number of collisions in most scenarios.Keywords: MANETs, MAC layer, Deaf/Masked nodes, Throughput, RTS/CTS

The Internet and the Quality of Life

Rolf Martens, Malm, Sweden

Since humans very much are "herd animals", a fact on which the entire civilization depends,that possibility of people's getting into contact with each other internationally which theInternet provides already today has large consequences for that which you can call theirquality of life. This inevitably and ironically is the case above all concerning such contactswhich those who began organizing the Internet in the first place have good reasons todislike. It offers a new possibility for the very many to unite against the very few. And thisimproves the quality of life for the former very much, even if they may not always realizethis consciously. Actually, of course not for all of those "very many" does the Internetprovide a possibility of improving their quality of life, I must add at once. In many countriesin the world today, obviously, there are millions of people who live under such conditionsthat their main or even only concerns for improving their quality of life, or even for stayingalive, is to find sufficient food, shelter and clean water for this, and/or to avoid direconsequences for themselves of a war of aggression to which they are being subjected.

Device for Obtaining a Predetermined Substantially Constant Force in Particular for

Muscular Training

Vojin Plavsic, Vitamedic Sweden HB, Sweden, [email protected]

The rubricated device produces predetermined substantially constant mechanical force, fromnearly zero to a determined max value. The aim of our invention is to eliminate the largeinertia forces appearing when lifting weights, at high accelerations and to totally change theway of physical exercise by elastic resistance. During our research and development wemade it possible to make elastic resistance constant, but not only that we can now alsoadjust the resistance in a very simple way. With normal weight training its impossible to getthis effect because of gravitation effects.

Multicriteria Choice and Outranking Methods Aggregation in a Software Agent for

Ranking Land Parcels

Zbigniew PiotrowskiInstitute of Information Systems, Szczecin University of Technology, Szczecin, Poland

Premises for an intelligent software agent to search and rank land parcels according tospecified criteria. Criteria are given by the Decision Maker (presumably a group of managersfrom a company). A pool of land parcels is provided by local authorities. The decision modelwill take into consideration crisp values as well as linguistic data both for preferences andattributes. Due to various types of attributes which are used to describe both the DMspreferences and land attributes, a combination of multi-criteria choice and outrankingmethods will be used. A sensitivity analysis will be done for each considered land parcel toprovide local authorities with feedback information about improvements needed to advancein the ranking.Keywords: decision support, multi-criteria decision aid, software agents

The Next Frontier - Peer Commerce

Dragan Kopunovic

"Like content was king in the 1990s, in the days of Web 2.0, community is the kingdoWired Magazine, Commentary by Regina Lynn

The last few years are marked by unprecedented success of social networks. Most of themgather networks of millions of peer participants and focus on exchange of messages, files,videos, music, etc. Current untapped potential of these networks lies in their ability toconduct business for the benefit of peers. What would it take to be able to use socialnetworks not just to announce a new small business venture, new business interest, or new-found business opportunity, but to actually close the business by being able to sell, deliver,and manage a product or service over such networks? What would it take to achieve "peercommerce"?

The professionals in cultural memory institutions archives, museums, archaeologysites, need new competencies in ICT (Information and Communication Technologies)to work in the acquisition, organization, management and digital exploitation of culturalheritage contents. Multimedia and Web technologies require continuous update and

acquisition of new knowledge and skills, especially for memory institutions professionals.The main goal of this paper is the discussion of this problematic, complemented by thepresentation of the approach and the results of a European Project (JASON).

A Study of Operating Lease Efficiency

Sang-Bum Park, Korea Aerospace University, Korea

We use BCC and CCR model of DEA to measure efficiency of samples in using operatinglease. We test whether such efficiency of samples impacts their operating profit significantlyor not. We find operating profits of efficient and inefficient samples are significantly differentaccording to Mann Whitney U test. We also find for the efficient samples that the ratio oflease rent to operating expenses (LROE) is higher than the interest to operating expensesratio (IEOE) and the average tax rate of efficient samples is also lower compare to that ofinefficient samples. Thus, the results are consistent with those of Graham, Lemmon andSchallheim (1998).Keywords: Operating Lease, Inputs and Outputs, Data Envelopment Analysis, BCCefficiency, CCR efficiency and Scale efficiency, IEOE and LROE.

A Serious Game to Promote Road Safety

E. Baldi, F. Bellotti, R. Berta, M. Pellegrino, L. Primavera, A. De Gloria{baldi.enrico, franz, berta, pellegrino, primavera}@elios.unige.itDepartment of Electronics and Biophysical Engineering, University of Genoa, Genova, Italy

Serious Games can join their capability to engage and entertain with a potential to train users

in a target application field. In this context, we have developed Road Rider, a 3D videogameaimed at promoting road safety among middle and high school students. The game lookssimilar to commercial videogames, but all the important game situations and reward/penaltyscore mechanisms are tied to road safety. This implies that users should learn about roadsafety seamlessly, as players learn tricks in usual videogames. The project has activelyinvolved end-users to focus on usability issues and steer the design process according to theuser needs. In this paper we present quantitative data analysis and understanding gainedfrom an early user test, with 56 students coming from three different schools. Results show agood students game acceptance, in terms of usability, ease of use, enjoyability, playabilityand graphic quality.

Cross-Disciplinary Work in Visualization: Requirements for a Code of Conduct

J. Leng1 , W. Sharrock2 1 Manchester Computing, University of Manchester, United Kingdom2School of Social Sciences, University of Manchester, United Kingdom

This paper argues that the 'success' of a visualization is commonly judged in terms of itsadoption - if the visualization technique is taken up in the relevant research community, thisis taken as indicating that the technique was a technical success in meeting the needs of theresearchers. What is not usually considered in such appraisals, what goes characteristicallyunreported, and does not therefore become public within the visualization community is theextent to which the fate of a technique may be decided by other than purely technical factors.If an effective 'visualization contract' is to be developed as a basis for cross-disciplinarycollaboration between visualization specialists and domain experts then it will need to paymore attention to the establishment of conditions that are favourable to the preparation of atechnically effective visualization. The idea that the adoption of technologies depends uponmore than their strictly technological qualities has been maintained by the 'SocialConstruction of Technology' approach which insists that social, practical and politicalfactors affect the response to technologies. This paper will provide an initial discussion ofsome of the conditions which are important to technically successful collaborations andwhich have effects on the take-up of a visualization technique. We will include some of theprofessional, practical, organisational and disciplinary features of research disciplines thataffect the visualizers capacity accurately to capture requirements and that subordinate theneeds of the visualization project to the demands of professional etiquette, scientific creditand credibility, as well as to professional hierarchy. Thus we will consider the organisationof relations within and surrounding the visualization project, but will also look at theposition of the visualization project within its professional field, how the state-of-play withinthe discipline may marginalise issues of visualization.Keywords: Cross-disciplinary research management

Knowledge Structure of Chart Sequences and its Application to Learning System

Susumu Yamasaki and Mariko SasakuraDepartment of Computer Science, Okayama University, Okayama, Japan

To implement learning of programming language, we deal with knowledge structure of

chart sequences, where the chart contains information on learning and on acquisition of moreknowledge. A sequence of charts makes a performance of procedure causing situationtransitions, where the system based on formation of chart sequences has characters such that:(1) The charts are media for knowledge, which may denote not only objects but alsoprimitive procedures. (2) The situation is referred to by name, but not always by its detailedstructure. (3) The organization of chart sequences may be automated. We implement alearning system which is mainly constructed to take formation of chart sequences, and whichis applied to exercise practice for programming language. The standpoint of our work isdifferent from those of adaptive learning, logic-based AI and agent technologies.Keywords: Knowledge Processing, Semantics, Language Learning (ISY)

Internet-communication as the Political Resource of the Postmodern Society:

An analysis of the Present Situation and Discussion of Prospective of Developing Projects

in Russia

Andrey N. YershovRector of the Academy of Public and Municipal Administrationunder the President of the Republic of Tatarstan, Kazan, Russia

Virtualization is a new sphere of the communicational area of the modern world. TheNetwork is a cyberspace capable of changing the political system reality. The gap existing between society and government, distrust of population towards power-owners encouragethe alternative forms of the political dialogue in the network space creating feeling offreedom of individual citizen choice. Virtualized communication between government andpopulation creates new reality, new political practices, at the same time transformingpolitical and public institutions. In this paper, the nature and the consequences of theimplementing Internet in the mode of governance are discovered by means of analysis of theapplication of present information technologies based on the survey of the developingprojects in Russia.Keywords: Informational community, Virtualization, E-government, Digital Democracy

TV is Dead Long Live the WEB (SSGRR-2000)Harold Kroto, Nobel Laureate, University of Sussex, United Kingdom

Science, Engineering and Technology are as vital to our intellectual and cultural development(particularly our childrens) as they are to our training to get along in the Modern World. Some effortsto redress the problems involved in the general Public awareness and understanding of science andengineering (PAUSE) issues are being initiated via the Vega Science Trust (www.vega.org.uk), whichaims to take advantage of the revolution in TV and Internet communications technology to improvematters. The best scientists and science communicators are being recorded and the programmes are being broadcast on BBC-TV and the Internet. Furthermore School/University outreach programmesare being developed and Vega is piloting ways in which members of the Science, Engineering andTechnology (SET) community can, as individuals and groups, make important contributions. Excerptsfrom SET programmes will be presented. These efforts present a perspective on SET which places thecultural factors in the foreground and focuses on the intrinsic charisma of science which is hiddenfrom many. It is now crucial that the society in general and the scientific community in particularaccept that serious problems are involved in communicating science and the Internet is set to play amajor role.

Electronic Business and Education (SSGRR-2001)Bob Richardson, Nobel Laureate, Cornell University, United States of America

There is no longer any question that the Internet and electronic communication are the major newtools for collaborative advances in the creation of new knowledge and in future learning. There arecountless examples of highly successful professional courses taught on the Internet. Similarly,international and multidisciplinary collaborations in scientific research based upon little contact otherthan through electronic communication dominate the scientific literature. Perhaps the most profoundexamples of distance collaboration in science are found in astronomy. The Hubble telescope haspermitted astronomers to gather breathtaking images from the most remote observatory imaginable one in orbit around the earth. A significant challenge remains. The challenge is to devise a remotemode for nonverbal communication about difficult concepts. In the shared creation of new ideas andknowledge, facial expressions and body gestures frequently play an important role in peerinteractions. As the speed and bandwidth of electronic communication increase, we have the prospectthat the important elements of human contact can be imitated. Without the development ofsympathetic peer or mentor relationships, distance learning will remain quite sterile.

Mastering the e-ScienceHerbert Simon, Nobel Laureate, United States of America

Our generation like all its predecessors leaves many tasks hopefully no more than it inherited forthe next generation to take up; but even knowing that it must be so does not remove ones sense ofloss in the parting.

Computer Architecture: Concepts and SystemsKenneth Wilson, Nobel Laureate, United States of America

The coming of the computer has created a revolution as profound as the change from the Middle Ageto the Renaissance. Many of the changes that took place around the time of the Renaissance theinvention of printing the development of systematic experimental science, the invention of oil painting have analogs today, made possible by the computer.

E-Business and E-Challenges (SSGRR-2002) Jerome Friedman, Nobel Laureate, MIT, United States of America

The development of Homo sapiens has been a history of innovations, from the earliest crude tools tothe modern technological society of today. The growth of science and technology has been exponentialduring the last century; and under the right circumstances, this rapid growth can be expected tocontinue. The major innovations of the future - those that will shape the society of the future - willrequire a strong foundation of both basic and applied research. It is ironic that quantum mechanics,one of most abstruse conceptual frameworks in physics - one that was developed to explain atomicspectra and the structure of the atom, lies at the foundation of some of our most importanttechnological developments, because it provided the understanding of semiconductors that wasessential for the invention of the transistor. Quantum mechanics thus contributed directly to thedevelopment of technologies that gave us world wide communication, computers with theirapplications to all phases of modern life, lasers with many diverse uses, consumer electronics, atomicclocks, and superconductors - just to mention a few. The internet and the World Wide Web, which areprofoundly reshaping the way that we communicate, learn, and engage in commerce, owe theirorigins in a deep sense to the physicists of the past who worked to understand the atom. In modernindustrial nations, quantum mechanics probably lies at the basis of a sizable fraction of the grossnational product.

The Next Generation of IP Flow Routing (SSGRR-2003)Lawrence G. Roberts, Father of the Internet, United States of America

For the last 33 years IP routers have not changed, they still support only best effort traffic. However,the bandwidth available to people has been increasing rapidly with the advent of broadband access.The result is that many new services are now desired that require far better QoS than best effort IPcan support. Also, with broadband, the problem of controlling the total usage and carrier expense has become important. Thus, it has become critical to improve both the delay performance and the controlof bandwidth for IP service, much as was accomplished in ATM. Also, call rejection for high bandwidth streaming services like video is required instead of random discards if quality is to bemaintained. All these problems can be solved with no change to TCP/IP by routing flows rather thanpackets. This requires keeping some state information for the duration of the flow, but thisinformation can be captured on the fly as the first packet goes by. This permits an IP flow router toachieve all the capabilities of an ATM switch, but without the call setup delay and at a lower cost thana conventional IP router.

Neural Networks: Concepts, Applications, and ImplementationsLeon Cooper, Nobel Laureate, United States of America

When interest in neural networks revived some fifteen years ago, few people believed that suchsystems would ever be of any use. Computers worked too well; it was felt that they could beprogrammed to perform any desired task.

Number and Organization of Primary Memory Objects in the Brain (IPSI - 2004 Montenegro)P.G. de Gennes, Nobel Laureate, College de France, France

A memory area contains a large number (N ~10) of neurons, each of which is connected with maneighbors (number of efferents: Z ~104). But the connections are poor: the probability for oneconnection to be efficient is p ~10-2. This is important: different memory objects must be independent.We discuss how a definite memory object can be stored on a cluster of well connected neurons, andwhat is the statistics of these clusters. The average number M of neurons per cluster is containedwithin two limits: if M is too small, the memory is not faithful. If M is too large, the storage capacity istoo small. Various consequences of this picture will be presented.
