ABSTRACT: A feeding trial was conducted to evaluate the effect of inclusion level of cooked Delonix regia seed meal
(CDRM) in the practical diet of Oreochromis niloticus fingerlings through their growth performance and nutrient
utilization for 56 days. Four iso-nitrogenous and iso-lipidic experimental diets were formulated to contain 35% crude
protein and 9.5% lipid, CDRM was included at different varying inclusion levels viz: 0, 10, 15 and 20 and were designated
as D1 (0 % inclusion), D2 (10 % inclusion), D3 (15 % inclusion) and D4 (20 % inclusion). Each treatment was allocated to
three tanks of twenty O.niloticus per tank with initial mean weight of 1.18±0.10g. There was no significant difference
(P>0.05) in the survival rate of all the treatments, D2 has the highest value in percentage weight gain, specific growth rate,
feed intake, protein efficiency and protein retention, while D4 (20% inclusion) had the lowest value in all the growth
parameters and feed utilization measured. However, there is no significant difference (P>0.05) between fish fed D3 (15%
inclusion) and D1 (control: 0% inclusion). Proximate composition result revealed that increase in the inclusion level of
cooked Delonix regia lead to an increase in carcass lipid content and a decrease in the moisture content of the fish fed
experimental diet. The results indicate 10-15% inclusion of Delonix regia seed meal improved growth performance and
nutrient utilization of Nile tilapia fingerlings.
Key words: Oreochromis niloticus; Growth performance; Delonix regia;

ABSTRACT: The aim of this study was to examine the impact of haemoglobin variants HbAS and HbAC on
asymptomatic malaria compared to normal HbAA among adults living in a malaria hyperendemic area. Seemingly healthy
individuals, 2,237 (≥16 years) without clinical symptoms in Iwo, Southwestern Nigeria were screened for this study after
informed consent was obtained. A sample of 5 mL of blood was withdrawn from each participant for examination of
malaria parasite and haemoglobin genotype. Thick and thin Giemsa stained blood smear were prepared for malaria parasite
identification and quantification. Haemoglobin genotype was determined by cellulose acetate electrophoresis. The results
showed that compared to HbAA, malaria infection and parasite densities were significantly lower in Hb AS (ᵡ2 = 26.66, p <
0.001; t = 5.05, p < 0.001) and HbAC (ᵡ2
= 6.51, p = 0.01; t = 3.70, p = 0.002). However, there was no significant
difference between HbAS and HbAC individuals with respect to malaria infection and parasite density (ᵡ2 = 0.21, p = 0.64;
t = 0.22, p = 0.83). These findings suggested that among adults living in Iwo, Southwestern Nigeria, HbAS or HbAC
offered better protection against asymptomatic falciparum malaria infection than HbAA while HbAS and HbAC offered
similar protection.
Key Words: asymptomatic falciparum malaria; haemoglobin electrophoresis

ABSTRACT : The purpose of this paper is to propose a conceptual model which would provide a better understanding on
how social influences through the effect of peer communication could interplay with materialism to capture the effect of
young adults’ adoption of technological innovation in their life. This paper provides a brief review on the theories
associated with the adoption of technological innovation as well as some important empirical findings to support the model
of this study. Based on a review of established studies this paper re-examined the relationship between peer
communication and the adoption of technological innovations and propose that young adults’ interaction with their peers
have significant positive effect in their adoption of technological innovation. However, this paper argues that the effect is
not direct. This paper proposes that the relationship between peer communication and the adoption of technological
innovation could be indirect, through the relative mediating effect of materialism. Next, the relationship between
materialism and the adoption of technological innovation is examined as well as how the antecedents of materialism.
Finally, the paper concludes with a discussion on the limitations and the possible areas of research which researchers could
explore in the future.
Key Words: Young adult consumers, peer communication, materialism, adoption of technological innovation.

ABSTRACT:Essential amino acids such as methionine have been increasingly included into diets of lambs. However, few
studies have determined the effects of methionine supplementation in the general performance and economic returns of
lamb production. To address this question, 21 weaned male Rahmani lambs were allotted to 3 dietary treatments: control
diet (C), control diet plus 3.30 g of methionine/kg concentrate feed mixture (T1), and control diet plus 3.63 g of
methionine/kg concentrate feed mixture (T2). T1-fed lambs showed significantly higher (P < 0.05) total body weight gain
than those fed diets C. The digestibility coefficients of dry matter (DM), organic matter (OM), crude protein (CP), ether
extract, (EE), and nitrogen free extract (NFE) for T1 and T2 were significantly better (P < 0.05) than for C. Economically,
dietary feed T1 and T2 increased the net profit by 329.64 Egyptian pounds (EGP)/lamb and 305.76 EGP/lamb,
respectively, as compared with the control diet. In addition, the economic efficiency (average feed cost/kg of body weight
gain) was 10.02 for C and T1 and 10.48 for T2. Total costs were similar between the 3 dietary treatments. In conclusion,
feeding growing Rahmani lambs with 3.30 g of methionine/kg concentrate feed mixture improved their growth
performance and raised their economic value.

Abstract
Today, the need for air-conditioning systems for large buildings has led to systems with high efficiency and low energy
consumption unnoticed. That's chiller with centrifugial compressors and application of nano-fluid phase is considered. In
the current study flow in centrifugal compressor is of the most complex issues in the turbo compressor machine. This is
because the asymmetric geometry of the blades (volute) and presence of the secondary stream is that it is far more complex
in a multi-stage centrifugal compressor Because of the wide range of study and research is too complex. Projects have
included extensive study of the two-stage centrifugal compressor with intercoolers in between stage. Its application in the
use of nano-fluid in chiller for use in the cooling tower through the use of nano-cooling fluid as the first time.

Abstract
When the courts of a country encounter with a legal relationship in which there is a foreign element, conflict of law issue
arises. It means that the court must decide which of the proposed law will apply.During the last few decades party
autonomy has become a topic of discussion in this area, especially in family matters. Often, the admission of party
autonomy can be explained by the need for conflict of law certainty, especially in the areas of international matrimonial
property and internationalsuccession, but another area that can be considered in relation to party autonomy in international
trade law is a contract. What this article will be considered is party autonomy, according to Iranian law, in particular with
regard to the provisions of some European countries in this regard and expressed its limitations.

Abstract
With the progress of human societies, trade turnover has exceeded the border. The complexity and diversity of the
different cultures and the lack of a common language that everyone with any intellectual profession adhere to its
rules and legal topics in a different name, remember it is not sensible. Despite the similarities that soft law and legal
norms And sometimes mistakenly used interchangeably, This comparison differences between them and the
territory of any one of them is described briefly.In a sense, the non-binding soft law documents and
recommendations that are not legal binding stage but the power of flexible benefit and the norms of legal rules and
principles, and sometimes the custom in our country is different. In other words, it can be said While in some
respects the rights norms obsolete, but in the creation and formation of soft law and the law play a major role.Of
course, the same basic principles and legal norms that have become the universal rule Unfortunately, despite being
written and binding independent states are not in a single article And even chapter does not have in their laws.
Through this relationship we want to have someone who was paid to it from this perspective Step in developing
effective legal norms and unification of private law, especially in the field of international trade survey. Take a look
back to the place that is the source of rights.

Abstract
The upward trend of global warming has increased the use of renewable energy, based on distributed generation sources
(DGS) for power generation. This study proposes a new load distribution algorithm in which the system frequency and
bus voltage of distributed generation sources are studied as load distribution variables. In addition, the performance of
distributed generation sources in controlled mode and constant power, performance of production resources Dispersions
are modeled on the basis of the control mode and the frequency of the network is used to supply the load between
distributed generation sources. These equations are solved by an improved optimization method. The objective function
used for the load distribution problem is to minimize the imbalance between production and demand in the network. The
results are plotted on two 6 bass networks, 69 buses, to show the validity of the proposed algorithm.

Abstract
What is currently known as suburbanization is no more than an old and historic process of migration by a group of people
seeking work and welfare and those escaping from villages and small cities due to their repulsions and the fact that the
poor are driven out from there to cities, particularly to the suburban areas. Hence, the emergence of suburbanization in
both Iran and the world has been accompanied by migration and its consequences. The formation of widespread
suburbanization in Iran in 1970s has been concurrent to increased migration of villagers to cities; i.e. when, on the one
hand, the expansion of urban facilities and communication networks as well as increased oil revenues had resulted in the
prosperity of cities and creation of urban attractions, and on the other hand, land reforms and agricultural mechanization
and inattention to basic transformations in villages and agriculture sector had aggravated rural repulsions. In this
connection, most migrants who could not afford to settle in the official limits of cities and could not cope with housing and
residence incurred costs in the legal areas of cities turned to the suburban areas for sheltering themselves.
Suburbanization is a product of life in the city which differs fundamentally with neighboring parts in terms of political,
social, cultural, economic, structural and legal aspects and history of settlement and development of historic processes.
Suburbanization is characterized by unordinary street houses, narrow alleys, health and environmental problems, increased
rate of population, cultural poverty and high vulnerability against natural disasters, low level of facilities and life
amenities, unofficial jobs as predominant employment, illegal land seizures, etc. Hence, one can say that suburbanization
is an example of social ills and deviance followed by such consequences as insecurity, development dysfunction and lack
of progress in the country as a whole. In this paper, after investigating rural migration in Iran followed by the way
suburbanization was formed, suburbanization features are divided into three physical, social and economic aspects based
on the researches done, and the article concerns with ills from suburbanization, including social and cultural ills, economic
ills, structural ills, environmental ills, security ills and political ills. In the end, guidelines and recommendations in three
strategies of prevention, empowerment and culture-building are provided based on the causes of formation of
suburbanization and the resulting ills.

The house money and break-even effects from futures markets
Mohammad Hussein Abdorahimian And Mahdieh Jivad
Abstract
In research using a set of transaction records from the futures Exchange, risk-taking behavior subject and the house money
and break-even effects study for various trader types. The empirical results show that the degree of morning gains/losses
nonlinearly influences afternoon risk taking for trader types, but the pattern is different for each type. Active individuals
exhibit a house money effect after experiencing large gains and exhibit a break-even effect after large and small losses.
Futures proprietary firms exhibit a break-even effect only after experiencing large morning losses. The additional risk-
seeking behaviors of futures proprietary firms and foreign institutions do not have a significant influence on market
volatility or liquidity; only active individuals' risk-seeking behaviors when facing large morning losses impact both market
volatility and liquidity.

Abstract Arbitration is a private dispute resolution authority that has been considered in the Iranian Civil Procedure Code .
According to Article 472 of the Code of Civil Procedure, arbitration is binding contract and, therefore, neither of the
parties can terminate it. Also under paragraph 2 of article 481 arbitration terminates by the death or motive of either party.
It is also said that if the subject matter of the arbitration is ruled out in a direction, the arbitration will also be excluded
from the issue. In addition to cases of decay, arbitration sometimes ceases to exist, and the continuation of this is subject to
another, and sometimes it is not possible from the beginning of the arbitration in certain matters. All of these matters will
be scrutinized here.

MA in General Linguistics
Abstract
Presupposition is one of the topics in semantic study and Pragmatics. In this paper the researcher is more concerned about
the discussion presupposition in pragmatic studies, where presupposition is in one's mind about everything that exists in
the world. In this paper the researcher use descriptive research method, because all the data comes from animation and the
data is reviewed based on theory of presuppositions. Presuppositions in Sing animation are taken from the conversations of
characters in the animation, and then analyzed by the theory proposed by Yule (1996) about the type Presuppositions to
find out what types are often used in Sing. Finally the researcher has found five types of presupposition which applied in
Sing animation, they are 12 existential (13%), 21 lexical (13%), 23 structural (24%), 15 factive (17%) and 18
counterfactual (20%). From this paper also, the researcher expect that this paper can be useful both in learning as an
additional science in learning pragmatics, especially presupposition.

In this paper, we intend to study the foreign policy Discourse of the eleventh government of Islamic Republic of Iran in
the perspective Ernesto Laclau and Chantal Mouffe. The main question of this research is that the foreign policy Discourse
of the 11th government of Iran can be explained and examined with the previous governments discourses? It seems that
Iran's government has been seeking to present a new presentation of foreign policy discourse which would further promote
the national interests of the country .As a result, the eleventh government has tried to focus its slogans in the international
arena on the concepts of "constructive engagement with the world" and "national dignity" as the preferred sign in its
foreign policy discourse, a new subject with the motto " Moderation and moderation "in order to achieve the goals of the
Islamic Republic of Iran at the international level, and, by incorporating the new concepts into consideration, seek a new
identity in the international arena. The purpose of this article is to explain and analyze the foreign policy discourse of the
eleventh government at the international level.

Abstract
In recent years, intense pulsed light, called IPL technology, is used by physicians to perform various skin treatments. This
technology uses a general range of 550-1200 nm spectral light sources. Usually, to filter lower frequencies and limit the
optical spectrum, different high-pass filters are used to place the structure and specific chromosomes. In IPL, excited light
passes through a optic filter with a certain wavelength, depending on the wavelength of the light to be used in different
therapies. In this paper, manufacture of a high-pass filter is intended at a wavelength of 580 nm.The BK7 substrate was
considered and the TiO2 and SiO2 materials were used for the desired filter layer. This coating was carried out by the
EDDY coating device in a thermal evaporation method, in the laboratory of Photonics and Quantum Technologies
Research School. Finally, with spectroscopy of made sample, a very good match with the prototype spectrum was
observed.

Abstract
Effective management in construction projects is highly associated with establishment of coordination in an arranged flow
of material, transportation, money and human resource. Supply chain management (SCM) which includes movement and
storage of raw materials, work in-process inventory, finished goods and relations between them from point of origin to
point of consumption, is a strategic and effective tool for increasing efficiency of construction industry. The purpose of this
study is to design a supply chain network which consists of evaluation and choosing of suppliers especially in construction
industry. Thus by analyzing previous studies in construction industry and other fundamental industries, a supplier selection
model based on integration of Geographic Information System (GIS) and Fuzzy Set Theory is presented. In proposed
framework, first supplier selection criteria and their weights are determined. Then score of suppliers associated with factors
and rank of vendors are specified. Eventually, the proposed model is employed for a real construction project to
demonstrate application. This model interacts with considerable share of human judgment in supplier selection process and
imprecision of most of data in mentioned area very well.

Abstract
This study explores social identity of people in Nadine Gordimer's (1923-2014) July's People (1981)based on postcolonial
theories of Homi Bhabha (born 1949) and Edward Said (1935-2003). Concepts such as hybridity, displacement, otherness,
ethnocentrism and negotiation are explored, using the aforementioned theorists. July’s People is set in South Africa during
Apartheid era when the regime employed racial segregation. The blacks were considered as subhuman and inferior and
these discriminations and othering of the blacks resulted in their poverty. The rising of the blacks and their riot challenged
the regime for its treatment of the blacks. This causes displacement for the Smales who run away from their home and go to
the village of their servant, July and changes nearly every aspect of life for them. Hybrid and ambivalent identity is another
issue explored here. Hybridity is traced in the lifestyle and language of people, a combination of their language and
English. There is also colonial negotiation between July and the Smales. It was somehow difficult for July to grasp the new
conditions. The novel depicts the whites in a weaker position as the blacks take control of many cities and the whites are
subject to bias, discrimination and displacement by the black fighters.
Keywords: ambivalence, colonial negotiation, hybridity, otherness, post colonialism.

Abstract
This descriptive study examines the figurative language and its characteristics and specifications in Farsi and English as
corpus study in form of a contrastive analysis on metonymy in English versus Farsi based on semantics. To compare and
analyze the metonymies found in English and Persian corpora, two models are employed which have a lot in common.
One model is by Safavi (2008) and the other belongs to I. Saeed (2008).These two models were originally introduced by
International Conference on ENGINEERING SCIENCES, Winter 2018

Lakoff and Johnson (1978).Based on these models. The researchers adopted a modified version in which 25 types of
metonymy were identified to be applied to English and Persian instances of metonymy. According to this modified
version, an attempt was made to classify each instance in both languages based on this model in this study. As a result, 215
metonymic expressions were identified from two books and their authentic translations in Farsi. Findings showed that out
of 215 metonymic cases 172 of them were metonymic in Farsi while 99 of them were metonymic in English. Only 23
cases were matched and 7 matched metonymies were found as a proposed model for Persian learners of English.

Abstract
Operational budgeting is a kind of planning, budgeting and evaluating system which emphasizes on relationship between
spent budget and expected results. In the frame of operational budgeting several official departments are responsible
responsiveness based on determined standards as operational parameters and managers are operationally more freedom to
determine the best method of achieving results. One property which provides field of conducting operational budgeting is
applying accrual base in accounting. This research aims to study the relationship between accrual accounting and
operational budgeting and improving responsibility of responsiveness. Results of conducted study show that compliance
and performance of operational budgeting in governmental systemsneed applying accrual accounting in order to determine
real expenses of programs and activities. In related studies operational budgeting also causes improve responsibility of
responding to executive systemsand this kind of budgeting causes to emphasize on responsibility of responding from
executive levels to level of programs.

Abstract
To use of CMOS technology, as well as the replacement of new materials in the devices, we need to increase the
functionality of the device. Using high-dielectric insulation materials in double gate SOI transistors can overcome
problems such as power dissipation and leakage. In this study, we investigated various insulation materials as oxide under
the gate in DGSOI transistors with a length of 20 nm. We concluded that HfO2 is a suitable option for DGSOI transistors
with a length of 20 nm due to higher cross-conductivity and lowering subthreshold swings and increasing the threshold
voltage . Also, in this research, a special type of device with dual material gate is considered, which in the term is referred
to as Disparate Dual Material Double Gate Junctionless SOIMOSFET (DDMDGJLSOIMOS). This particular type of
transistor improves the transmission of carrier, transients, and short channel effects. The results have been studied using
the Silvaco-Tcad two-dimensional simulator.

A Psychological Study of Orwell’s Nineteen Eighty-Four
through Jungian Personal and Collective Unconscious
Hamed Jamalpour
Ph.D student of English ,sub major Psychoanalysis at Saint Rose College, NY.USA
Abstract
This study aims to read George Orwell's master piece Nineteen Eighty Four (1984) with the help of Jungian theories. In
1984 Orwell creates a society of rebellious characters, cities in ruin and an oppressive, totalitarian government lead by Big
Brother. It is a world in which ignorance is bliss. The writer tries to examine the psychological behavior of each character
in the novel. Archetypes and myths or motifs which can be appeared in different genres and different times, but certainly

have the same psychological response and cultural function. Jung, the great, believed libido (psychic energy) to be more
psychic than sexual; also, he considered Freudian theories too negative because of the latter‘s emphasis on the neurotic
rather the healthy aspects of the psyche. Jung's primary contribution to this theory, was to develop the concept of personal
unconscious and asserted that beneath this is a primeval, collective unconscious shared in the psychic inheritance of all
members of the human family. Through the exact examination of the novel Nineteen Eighty Four we are going to see that
even for realities, governments can change reality by Double Thinking. In fact Double Thinking means changing the
reality to man- made reality, therefore this novel is a prominent example of literary works which casts off the usage of
psychological ways by governments to suppress the people. Within the story Orwell reflects the Jungian archetypes which
are dominant through the novel. For instance, as the novel opens, Winston (the main character) feels frustrated by the
oppression and rigid control of the Party which prohibits free thought, sex and any expression of individuality. So Winston
shows the Persona which Jung calls the social mask. Therefore the writer of this thesis tries to show the Jungian
approaches as used by Orwell in Nineteen Eighty-Four.

Geometrical, mechanical and electrical properties of carbon
nanocones

Department of Chemical Engineering, Ferdowsi University, Mashhad, Iran
Abstract
Geometrically, just as a sheet of paper with a wedge removed can be resealed to form a conical hat, a graphene sheet with
a wedge removed can be resealed, notionally, to form a cone or horn. The single-wall carbon nanocones form one class of
such conical structures. The pentagonal defects in carbon nanocones perturb the low-energy electronic structure both
locally and globally, defining both a local region of enhanced reactivity and a global geometric phase relation with
profound consequences for electron transport around the apex. The rapid variation in local sheet orientation around the
cone and the two-dimensional nature of the electronic states within imply that uniform laboratory fields can generate
highly nonuniform effective local fields for states in the cone.
Keywords: carbon nanocone, conical structure, electronic properties, geometric, mechanical.

Department of Chemical Engineering, Ferdowsi University, Mashhad, Iran
Abstract
Carbon Nanohorns (CNHs) are currently the subject of intensive research efforts, because their superior properties could
benefit many applications. This review provides an overview of Methods for CNHs Synthesis, using arc-discharge
methods. Mechanism of three main techniques were discussed; synthesis of CNHs by submerged arc, synthesis of CNHs
using the arc in water method with gas injection and Synthesis of CNHs by arc-discharge in air. CNHs with different
morphologies were generated by direct current arc-discharge between pure graphite rods in different atmospheres. Here we
show that three simple techniques that do not require relatively expensive laser and vacuum equipment provides an
economical alternative for the synthesis of CNHs.

Abstract
The existence of huge oil reserves in the Gulf region has made the region a major exporter of oil. Regarding the existence
of numerous countries with different policies and orientations in the Persian Gulf, various programs against oil exports
have caused other countries of harm. In recent years, among the three major oil producing countries in the region, Qatar,
Saudi Arabia and Iran, respectively, the first two countries have the largest oil exports to Japan and Iran to Sri Lanka. This
difference in stance requires further discussion, which can be seen in many of the reasons for reviewing strategic oil flows
in the region. This article, using the descriptive-analytical approach, tries to analyze the relations of their expression,
taking into account the geopolitical position of these countries.

reliability, validity and integrity, incontrovertibility, and authentication. In this scheme, both encryption and
authentication are performed without sharing the private keys. Each person performs desired operation through his private
key or the opposite party's public key. Anyone can send an encrypted message or review a signed message. However, only
the private key holder can decrypt or sign a message. Due to the effectiveness of this scheme in terms of running speed
and duration and the existence of security parameters, it can be used on a variety of security systems such as smart cards,

Abstract
The formation energies of the titanium interstitial in rutile TiO2 was calculated by the Hubbard-U approximation in the
projector-augmented wave density functional theory code, ABINIT. The Ti interstitial generates the defect states in the
gap. These are unpaired electrons lie on the interstitial and the adjacent Ti 3d orbitals. By applying a sufficiently value for
the Hubbard-U parameter of the Ti 3d states, the excess electrons localize spatially at the Ti sites. We found the inserted Ti
atom pushes away the adjacent O atoms, forming a longer bond length at the octrahedral site.

DFT study on electronic properties of zinc oxide
Mohammadreza Elahifard Chemical Engineering Department, Faculty of Engineering, Ardakan University
Abstract
First-principles calculations are performed to study the electronic properties of zinc oxide (ZnO) in wurtzite phase using r-
PBE GGA approach as realized in ABINIT code. Our analysis after relaxation shows that the ZnO has a hexagonal
wurtzite structure with lattice parameters, a= 3.24 and c =5.20 A °. Our results for structural parameters with GGA-r-PBE
are closer to experiment as compared with other forms of GGA. Also numerical values for band gap with GGA are in good
agreement with previous GGAs and LDA calculations, however are underestimated to the experiment measurements. The
electronic band structure of hexagonal ZnO was calculated to determine the energy band gap of ZnO, which was
determined to be 1.75 eV. Analysis of our computed band structure reveals that ZnO in wurtzite phase is a direct band gap.

Abstract
In this work, the density functional theory method has been employed to investigate the adsorption of CO2 molecules on
(0001) surfaces of ZnO. A complete understanding of the carbon dioxide (CO2) interaction with zinc oxide (ZnO) is a
basis for the development of new ZnO-containing materials for catalytic of CO2 into useful chemicals such as methanol. In
particular, it was found that the calculated equilibrium structure and inter-nuclear distances are in agreement with previous
work. Chemical adsorption of CO2 was studied at (0001) surface, with bidentate and tridentate species. Heat of adsorption

for the bidentate and tridentate species on oxygen terminated (0001) surface was calculated to be 390 and 360 kJ.mol−1
respectively using PBE functional which has a little different with previous result. This difference is partially due to
exchange correlation functional and the number of layers used, since there is no significant difference of our structure in
relation to the reported data.

Abstract
Enhanced oil recovery is referred to a process in which oil is recovered by energy or materials outside the reservoir and
conventional methods are not used anymore. One of the important issues in reservoir management is taking some
measurements to protect the reservoir, increasing the production efficiency and keeping it a good level over the time.
Indeed, an enhanced oil recovery process cannot be used for different types of crude oil and we should use a set of various
methods. One of the methods is microbial enhanced oil recovery method. In this method, microbes or microbial products
are used for enhanced oil recovery process and it is called MEOR. The most important difference of microbial method in
comparison to other enhanced oil recovery methods is using a living creature as the most important factor of this process
and this causes some limitations in using this method. To do this, we should find a microbe in conformity to the
temperature, pressure, water salinity, sulfur and other harmful compound in the reservoir and besides the evaluation of its
performance mechanism in the reservoir; the conditions are provided for its survival. The present study attempts to have a
comprehensive view to different dimensions and introduction of MEOR method.

Optimize Solar Chimney Power Plant by integrating with Solar
Power Plant
Aziz Hoseinpoor
Abstract
The solar chimney power plant is a system that increases the air temperature (air molecules) by using solar heat and creates
air flow. Using air density, air flow can be controlled and placed on a specific path. Ironically, this movement of the air
causes wind turbines to rotate. In front of the chimneys of the sun, there are solar cells made of dark-colored silicon,
preferably with an unreflected surface, and stimulated by light to the surface and release the electron and generate
electricity. It is noteworthy about solar cells that use only sunlight, and the heat of the sun and the environment reduces the
efficiency of solar cells, and it is imperative to always cool solar cells, which is part of the maintenance of solar power
maintenance. In this new system, using two power plants and integrating them together, we use both the production of two
power plants, and also the flow of generated air can be aligned that both cools the solar cells and rotates Turbine is a solar
chimney. As a result, a power plant with a lower volume of power can receive two power plants and more than two power
plants.

Abstract
Recent advances have given rise to the popularity and success of cloud computing. However, when outsourcing the data
and business application to a third party causes the security and privacy issues to become a critical concern. Throughout
the study at hand, the authors obtain a common goal to provide a comprehensive review of the existing security and
privacy issues in cloud environments. We have identified five most representative security and privacy attributes (i.e.,
confidentiality, integrity, availability, accountability, and privacy-preservability). Beginning with these attributes, we
present the relationships among them, the vulnerabilities that may be exploited by attackers, the threat models, as well as
existing defense strategies in a cloud scenario. Cloud computing has emerged as a platform that grants users with direct yet

shared access to remote computing resources and services. Cloud must provide services to many users at the same time;
the scheduling strategy should be developed for multiple tasks. In cloud computing processing is done on remote computer
hence there are more chances of errors, due to the undetermined latency and lose control over computing node. Hence
remote computers should be highly reliable. This is reason why a cloud computing infrastructure should be fault tolerant as
well scheduling properly to performing tasks.

Abstract
The prediction of crack growth and fatigue in a composite laminate are affected by the unique and complex methods in
which the cracks can grow in laminate, and should be considered during design. With the knowledge of the factors
contributing to the vibration phenomenon, one can expect the optimal design of the parts. In this research, the natural
frequency for composite materials reinforced by short fibers and long fibers with the effect of crack orientation in the
middle crack location on the plate, for different aspect ratios of the fixed-plate type with simple supported conditions in all
edges using artificial neural networks has been studied. Volume fraction of composite plate sample from 30% fibers and
an error propagation law and a feed forward model are used in multi-layer perceptron artificial neural network. In this
research, using artificial neural networks, the crack angle and the aspect ratio of the plate as a network input are considered
and in order to achieve optimal model and optimal output, which is the natural frequency of the composite plate, despite
the crack at different angles, The amount of different Root Mean Square Error (RMSE), Mean Absolute Percentage Error
(MAPE), Mean Absolute Error (MAE) and Coefficient of Correlation (R²) for all models are calculated as one and two
layers, and two models with structures 2-4-15-1 and 2-15-1, respectively, for the geometric dimensions of the sample plate

with short fibers and long fibers, were selected as optimal models. In order to verify the validity of the results obtained in
this research, the comparison between the artificial neural network results with the experimental results obtained from the
time of load variations and the measurement of the natural frequency of the plate was performed and the results were in
good agreement and showed that the trained network can well, predict the effect of the oblique crack on the natural
frequency of the composite plate. At the end, the effect of the crack angle, the aspect ratio and plate geometry on the
natural frequency of the composite plate were evaluated.

A dedicated private-shared cache design for scalable
multiprocessors
Sajad Mosaybi Department of Electrical, University of Science and Industry, Tehran, Iran, [email protected]
Abstract
Today, given the importance of speed in computing and data processing, all the attention is given to creating a way to speed
up the modern computers. With the advancement and development of technology, the computer architecture has come to be
multi-core. In multi-core computers, if a shared cache is used, it generates network traffic and overhead, which in turn
reduces the efficiency of the overhead. In this paper, two distinct caches are proposed for two separate workings. One is the
use of a dedicated and dedicated cache of a completely separate shared cache, which will open the space and reduce the
latency and invalidity. Information in the shared cache is shared uniformly by the cores, and the dedicated cache is separate
from each other in terms of information, resulting in the use of this method to speed up. On the other hand, this method
requires a coherent mechanism to specify the nature of the data, and eliminates the lag and cache problems.

Abstract In this study, the experimental study of the effect of iron oxide (Fe2O3)-water stabilized nanofluid on heat transfer in the thermal input
region of a horizontal tube was investigated. Also, some physical properties of nanofluid iron-water oxide were measured
experimentally and the effects of volumetric fractions of nanoparticles (0 ≤ φ ≤1) and temperature (25 ℃ ≤ T ≤45 ℃) were analyzed for
these properties. Experimental results show that the heat transfer coefficient of nanofluidic iron-water oxide increases compared to pure
water, and this increase can not be predicted by the Shah equation. For example, the nanosilver displacement heat transfer coefficient
with a one percent volumetric concentration of nanoparticles is more than 61% higher than pure water. Also, a significant decrease in
the heat transfer of the nanofluid of iron-water oxide in the 33.4×10-4 ≦Ha ≦136.6 ×10-4 (except Ha=36.3×10-4 was observed.

Abstract
Crack is among the most important causes of structural failures. As such, it is of paramount importance to detect crack
creation as soon as possible and at minimum cost. The presence of crack in a structure serves as a factor which modifies
structural characteristics of flexible object and affects its vibratory response. Therefore, the use of vibration data as a
non-destructive, low-cost, and fast method can be applied for the detection of crack position. Natural frequencies and
modal shapes of structure are sensitive to changes in stiffness and mass matrixes of the structure. Therefore, one can
determine intensity and location of defects by measuring the changes in dynamic properties of the structure. Even though
the sole presence of crack in structure can be relatively easily detected using the changes in natural frequency, but this is
not the case when it comes to the crack location. In the present paper, a method based on application of harmonic force

(forced harmonic vibration) is adopted for the detection of vibratory parameters and detect the defect location in
continuous systems such as beams. Accordingly, considering the necessity of analyzing and implementing the proposed
method, numerical simulations were conducted using MATLAB Software to characterize vibratory parameters (e.g.
stiffness and damping) of discrete systems, and the results were then investigated. The results indicated that, applying the
mentioned method, cracks can be nonlinearly modeled in beams, with their locations explored. Moreover, using stiffness
matrix of the cracked element, the crack location within the beam was detected and its depth was calculated. The
mentioned approach demonstrated efficiency of this algorithm in detecting different modes of damage.

Abstract
Owing to the importance of experimentation and measurements in natural science and engineering disciplines,
construction of mathematical models is an integrated part of the research performed on characterization of elastic systems.
Since the use of full-size models would incur large costs and took much time, different system identification methods have
been presented for the purpose of modifying software models to replace full-size models. System identification methods
can be used to determine properties of a software model in such a way that it simulates the behavior exhibited by the
corresponding real model. In the present paper, a method is developed for filtering experimental data; it is then used to
identify vibratory parameters and detect defect location in continuous systems such as beams. Accordingly, considering
the necessity of analyzing and implementing the proposed method, numerical simulations were conducted using MATLAB
Software to characterize vibratory parameters (e.g. stiffness and damping) of discrete systems, and the results were then
investigated. Applying the afore-mentioned method, cracks could be nonlinearly modeled in beams at high accuracy.
Moreover, using stiffness matrix of the cracked element, the crack location and depth within the beam were accurately
computed, indicating efficiency of this algorithm in detecting different modes of damage. In this paper, considering
practical limitations such as measurements in short time intervals, a method based on the application of harmonic force
(forced harmonic vibration) was presented for detecting vibratory parameters and locate defects within continuous systems
such as beams.

Abstract
Thr Pressure vessel are one of the most used parts in the industry and It is said Enclosures closed to be used to keep the
fluids pressurized above the Environmental pressure. These vessells are designed spherical or cylindrical and have a lot of
applications in the industry. The most common types of these vessells are cylindrical with two elliptical caps. These types
of vessells according to the type of operational need or installation location can be horizontally or vertically. For safe
design of tubes and Pressure vessel with Surface and peripheral cracks, Taking into account the conditions under
continuous loading, Usually considering the growth of fatigue cracks seems essential. In this paper, j integral values are
calculated using the finite element method in abaqus software for semi-elliptical cracks that have been created in the stress
concentration of pressure vessels is obtained. The results indicate that the integral value of j is constant amount and
independent of the path.That is, its value in a specific node of the crack front and on the different contours of course,
except the first contour, which is an exception, almost identical. On the other hand, since the J integral has the nature of
energy, Therefore, the negative is not the physical concept and the negative values are related to the integration of it.

Abstract In this study, the effect of zirconium oxide nanoparticles on the thermal conductivity of water / ethylene glycol was
investigated in vitro. Therefore, zirconium oxide nanoparticles (ZrO2) based on water and ethylene glycol mixtures (with a
ratio of 20/80, 40/60 and 50/50) were used. Ultrasonic waves were also used to stabilize nanoparticles in the base fluid.
Experimental results show that the ethylene glycol conduction heat transfer coefficient is less than pure water. With
increasing temperature, the ethylene glycol conduction heat transfer coefficient is increasing. By adding ethylene glycol to
pure water, the conduction heat transfer coefficient decreases relative to pure water. Also, with increasing temperature, the
conduction heat transfer coefficient of the water mixture and ethylene glycol increased. The addition of zirconium oxide
nanoparticles in a different volume fraction to the base fluid (water mix and ethylene glycol) has an increasing trend in the

conduction heat transfer coefficient. For example, at 80 °C, zirconium oxide nanoparticles with a concentration of 2% vol
as compared to the addition of zirconium oxide nanoparticles with a concentration of 0.5% v/v increased 16.26% and
compared to the base fluid (water and ethylene glycol with 50/50 ratio) We have a 38.5% increase in the conduction heat
transfer coefficient.

Abstract
In the old government, the government did not have civil responsibility, but it was gradually referred to this responsibility
among legal regimes. Nowadays, civil responsibility of the state is accepted as a principle, and personal responsibility,
responsibility for non-liability and liability arising from objects, and even the responsibility of the state towards the
exercise of the judiciary. Since the civil responsibility of the state, part of the public law, and more specifically, is a part of
civil rights of the public, and it is not solely devoted to private property, and the state as a public official in public law is
responsible for its actions. In this article, while addressing The pillars of the civil responsibility of the government for the
theory of this in the field of public law have been addressed and the status and attitude of our legal system (Iran) towards
civil responsibility of the state during the mentioned issues.

Abstract
Tabari's History (313 AH) is one of the sources of historicist writing that has been taken into consideration by the later
historians; Some have come up with praise and expression in the history of Tabari, and others, like Ibn Khaldun and Ibn
Atir, have questioned the contents of Tabari's reports. Achieving truth and historical realities in such conditions is difficult,
but it is possible, provided that scientific criteria are met in the assessment of historical propositions. This article tries to
study the content pathology of Tabari's historical reports and finally concludes that; Incorrect reports and reports of the
Israelis in Tabari's history, such as Zabihhh know Ishaq by attributing speeches to the Prophet (PBUH), Hadiths of
materialism and materialism, having God, the narrations of determinism, narratives of the creation of "pen", The traditions
of the days of God's creation and comfort, and the errors of the prophets, such as the legend of David with Betheshebe, the
wife of Ourya Hitti who are definitely alien to the attention of the evidence and reasons, Providing historical data on the
Qur'an and authentic tradition, studying the narrations, utilizing the wisdom and other sources, reveals the truth.

Abstract
Cadmium Telluride Polycrystalline (CdTe) is used as a promising absorbent layer in high-density thin film solar cells. The
CdTe absorption coefficient is of the order of 105 cm
-1, which makes these layers suitable for solar cell consumption. With
this absorption, a layer with a thickness of a few microns is sufficient to absorb 90% of the incident photons. In this paper,
a fluorinated doped tin oxide layer (SnO2: F) has been used to increase the efficiency. Initially, the cell made in the
laboratory was simulated using the software and then examined. Finally, to increase efficiency, the thickness of the
absorbent layer was changed.

Abstract
Nowadays water consumption in many countries has reached to alarming level. So they should use an alternative for this
goal. Air-cool condensers and dry cooling towers are good substitutes for this action, but they have limitations. The most
important limitation is higher heat rejection temperature in warm seasons and it leads to higher condenser pressure which
produce backpressures at the condensing turbine’s exit especially during high speed wind. In this study an absorption
refrigeration cycle for heat rejection from condenser of Mofateh steam power plant is investigated. In this study, we use an
absorption chiller system with air cooled cooler instead of existing wet cooling system of Mofateh power plant. The heat
that power plant condenser is rejecting is handled by the evaporator of absorption chiller and lift up to a higher temperature
where the absorber and condenser of absorption chiller are handle it with air cooler heat exchangers. The Generator
(desorber) fed by the steam that extract from power plant itself. Therefore, there is no consume of water in power plant
condenser. The effect of main parameters such as generator and air cooler temperatures were studied and results presented
here. At the end, we used a real absorption chiller system to have a comparison. As results shows there is a stability in
turbine’s work and cycle efficiency while ambient air temperature changes.

Abstract
Some of the musical movements of the early 20th century made various experiences in discovering and producing new
sounds, so that electronic instruments as well as mechanical facilities of sound production are some of their achievements.
Although conservative composers did not approach to such experiences at first, but since the second half of the 20th
century, with the expansion of the thought of starting from sound to reach music, a new phenomenon called electronic
music was shaped and developed by some composers. The history of this music is entirely dependent on the development
of electronic technologies and has been transformed widely since the late 20th century with the spread of computer use. In
fact, computer with the simulation of electronic circuits as well as the programming capabilities, could better achieve the
goals of electronic music, to some extent that today laptop has become a kind of electronic portable instrument. The present
article considers the historical development of this music and introduces its prominent status in the future.

Abstract
Today, the use of distributed generation units in distribution systems has increased dramatically in many parts of the world
to improve the distribution system parameters. In the meantime, it is necessary to investigate possible problems and
problems in the distribution system due to the use and utilization of scattered resources.
Dispersal products (DGs) are small production tools that can be connected to any point in the power system. By optimally
utilizing these units, it can reduce system losses, improve the voltage profile, increase load capacity, and release thermal
feeds. Designing distribution systems in the presence of DG requires definition of various parameters such as best
execution technology, number and capacity of DG units, best location and type of network connection. The issue of
exploiting scattered resources is very important. Installing DG Units in non-optimal locations can lead to an increase in
system losses, an increase in costs, and thus have a counter-result to the desired result.
In this research, the main problem of optimal utilization of distributed generation and its effect on the distribution factors of
the distribution network. Another goal is to investigate the effect of the random behavior of loads on the distribution system

on improving the system's loading capacity by DG. This research shows that the optimal exploitation of distributed
generation generators can affect how well the system's voltage and loadability profile can be improved.

Abstract
Today, Cluster based routing protocols are the most useful schemes for extending Wireless Sensor Networks lifetime
through dividing the nodes into several clusters and electing of a local cluster head for aggregating/fusing of cluster nodes
data and transmitting a packet to Base Station. However, there are several energy efficient cluster-based methods in the
literature; most of them used the topological neighborhood or adjacency as main parameter to form the clusters. This paper
presents a new centralized adaptive Energy Based Clustering protocol through the application of Self-organizing map
neural network (called EBCS) which can cluster sensor nodes, based on multi parameters, energy level and coordinates of
sensor nodes. We applied some maximum energy nodes as weights of SOM map units, so that the nodes with higher
energy attract the nearest nodes with lower energy levels. Thus, a cluster may not necessarily contain adjacent nodes. The
new algorithm enables us to form energy-balanced clusters and distribute energy consumption equally. Then the number of
clusters will be optimized by means of FPAKM algorithm.Moreover, we proposed a new cost fuction to incorporate
different useful criteria for election of Cluster head nodes with energy efficiency. Simulation results for different scenes
and comparison of them with previous similar protocols (LEACH and LEA2C) prove that the new algorithm is able to
reduced latency and energy consumption.

Abstract
Silicate bioceramics have attracted too much attention as a new family of biomaterials in hard tissue regeneration
applications. Investigation have shown that novel bioceramics sush as Akermanite and wollastonite perform better than
Hydroxyapatite in repairing bone tissue and possess better mechanical and bioactivity properties. In general, Akermanite
and Akermanite composites have better osteogenic properties than Diopside, Merwinite and other calcium-magnesium
silicates from the Millite family. In this study, Akermanite and wallestonite based on Cao , Mgo , Sio2 that have recently
been known as bioactive bioceramics , were syntherized via a sol-gel approache and calcined in varions temperatures.
Phase analysis were investigated and characterized using XRD , SEM. The results of xrd confirm the formation of pure
merwinite and wollastonite with grain size of aboute 16.72 nm respectively. Regaeding all the obtained results , it can be
noticed that merwinite and wollastonite bioceramics having Ca , Mg , and Si can be used az new and promising
biomaterials in bone tissue repairing applications. Thse bioceramics have a wide range of aplications in the filds of tissue
engineering and repairing diseased tissues due to their unique properties like bio compatibility , bio degradability non
toxicity and their stability in body`s physiological environment.

Abstract
LaMnO3 perovskite was prepared by the sol-gel auto-combustion method, then supported on CeO2 as a support by
impregnation method and was tested in the process of catalytic NO reduction with CO. Structural characterization,
morphology and crystallite size was performed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The
XRD study analysis showed that the LaMnO3 compound crystallized in a perovskite hexagonal structure and CeO2
indexed to a cubic fluorite structured. The result of SEM indicated the well dispersion of the perovskite oxide on the

support. Conversion of both reactants NO and CO for LaMnO3/CeO2 is higher than LaMnO3, due to the higher dispersion
of LaMnO3 on the support. LaMnO3/CeO2 has more tendency to reduce CO and convert it to CO2 as a product.
