Abstract:
Recycled concrete aggregate (RCA) is produced by properly crushing and sieving the demolished waste to
obtain required size of aggregates that will substitute the need for virgin aggregates (VA). The economic and
environmental benefits of using (RCA) from construction and demolition (C and D) activities have become clear
in the recent years. The use of RCA in highway construction, especially in HMA, shall also contribute in the
reduction of the consumption of VA as natural resources and the elimination of the stockpiles of concrete
wastes.A series of experiments using recycled aggregate of various compositions from building rubble was
conducted. This study evaluated the effects of replacing virgin aggregates (VA) by recycled concrete aggregates
(RCA) on local HMA binder (3B). Blending of RCA with VA can lead to combined aggregates which pass the
Egyptian standard specifications gradation. Increasing of RCA percentage in HMA leads to an increase in the
(OAC), due to the high absorption of RCA and Stability of the HMA binder (3B) decreased but still within the
Egyptian standard specifications by replacement of percentage of VA up to 80% by weight with coarse RCA in
HMA binder (3B). The use of RCA significantly reduced the loss of stability, and reduced resistance to rutting
for HMA binder (3B). Replacement up to 2% of powder by hydrated lime in HMA, leads to an increase in the
Marshall Stability value increased.

Abstract:
The ballast bed as part of the railway track fulfils the important functions as the binding element
between sleepers and substructure. Fouling increases over the years for various reasons. When the necessary
good functioning is no longer assured, ballast bed cleaning must be performed. The machines, that perform that
task, are equipped with various complex mechanics - hydraulic systems that ensure high productivity,
efficiency and quality of the works. In this article is presented one way of studying the work of the machine for
excavating ballast from the ballast bed to the sieving machine. We suggest a dynamic model for simulating the
work of a scraper chain of a ballast cleaning machine with different working parameters.

Abstract:
High-quality data transmission is the primary objective of WSN for achieving quality of service.
Heterogeneous wireless sensor networks (HTWSN) can be used to deploy in sensitive and unmanned areas
to monitor the objects. HTWSN is high configured network used to capture high-quality images and videos
of targeted objects. During the data transmission in HTWSN, we identified that, the formation of
interference with in the network due to link capacity overhead. Due to that, the quality data transmission is
not possible through the network. In this research paper, we described the deployment of HTWSN network
and identifying the primary sources for interference and introducing the proposed Interference
Minimization Protocol (IMP). The IM protocol has achieved better quality of service by minimizing the interference in HTWSN.

[Abstract]

Abstract:
No matter how societies have differed throughout history in their values, cultures, politics and systems of life,
there has always been a common consensus regarding the importance of mathematics and its role in the social
life. Arab-Islamic civilisation -like many others- had a reasonable command of many aspects of mathematics.
This was apparent in various applications including not just in everyday life, civil and business transactions, and
financial dealings, but also in certain religious rituals.
This paper aims to highlight the important position that the scholars in the Muslim East and West attributed to
mathematics, both in terms of teaching and practice. Furthermore, this work investigates the methodology of
teaching fractions in the Arab-Islamic society. The latter is found to be one of the mathematical subjects that has
been recommended to be taught to learners at their earliest learning stages, especially given the importance of
fractions in everyday transactions such as calculating shares of a legacy. The paper also examines some of the
educational requirements such as the teacher duties, student‟s qualities, education stages and what the relevant
curriculum recommended by scholars during each stage. Finally, this work briefly highlights one of the
contemporary issues which is the difficulty of teaching fractions for young learners and how this was addressed in the past by one of the early Muslim Arab mathematicians through the use of simple poetry.

Abstract:
The polyaniline were prepared by using different inorganic and organic acids via oxidative polymerization
method. The prepared samples were characterized by FTIR, the peaks are found to be at 507 cm˗1, 592 cm˗1, 798
cm˗1, 1138 cm˗1, 1244 cm˗1, 1302 cm˗1, 1471 cm˗1 and 1556 cm˗1. These predominant peaks may be
confirming the formation of polyaniline. The structural analysis was studied by employing XRD; found that
polyaniline is amorphous in nature. The SEM studies reveal that they are agglomerated, irregular and size of
these grain increases with increasing amount of polyaniline with different organic and inorganic acids. The dc
conductivity (dc) as a function of temperature (T) for polyaniline is studied in the temperature range from 30 to
1600C. At higher temperature it is found that conductivity increases because of hopping of polarons from one
localized states to another localized states. The ac conductivity of polyaniline was prepared by oxalic acid show high conductivity at 106 Hz. This is due to the space charge polarization and electrode polarizations.

Abstract:
E-commerce recommender systems are vulnerable to different types of shilling attack where the attacker influences the
recommendation procedure in favor of him by inserting fake user-profiles into the system. From one point of view, the
attacks can be of type push or nuke-either to promote or to demote a product. On the other hand, attacks can be classified as
high-knowledge or low-knowledge attack depending on the amount of system knowledge required for making the attack
successful. Several research works have been done in the last two decades for defending attacks on recommender systems. In
this paper, we have surveyed the major works done in this area by different researchers. After a brief explanation of different
attack types and attack models, we discussed the attack detection strategies proposed by the researchers mainly under five
categories- Generic and model specific attribute based, rating distribution based, outlier analysis based, statistical approach
based and clustering based.

Abstract:
A new Direct Torque Control (DTC) strategy for Induction Motor (IM) drive fed by a two leg three phase
inverter (i.e., Four switches are used in VSI) was proposed in this paper. The proposed methodology is based on
the emulation of operation of the conventional Six-switch three phase inverter. The combination of four
unbalanced voltage vectors is generated by the two-leg three phase inverter, approaching to the synthesis of the
six balanced voltage vectors of the conventional DTC. This approach has been implemented in the design of the
vector selection table of the proposed DTC strategy. Further, Fuzzy Logic Controller (FLC) is proposed in the
speed controller for the improvement of torque ripples. Convention DTC with Six Switch three phase VSI, twoleg
three phase VSI with PI and Fuzzy Controller are implemented using MATLAB/SIMULINK. Simulation
results have shown that the proposed DTC strategy, two-leg inverter fed IM drive revealed an improved
performance.

education, fashion design, dressing, information availability about certain things, communication from one place
to another and so on. That means, the people like intelligent automated life. In contrast artificial things can
interact with the human kind and solves their desires. For example, someone may have lost something,
somewhere, but they forget where they lost. The difficulty here is, how find the thing, someone may give the
solutions RFID technology but it works in certain range. So from the discussions, we need, the autonomous
mechanism, that can trace out the locality or information regarding to what we lost? In simple manner, we need
a common platform to integrate entire world of thing. For a little while, the common platform is internet and
hence we labeled Internet of Things(IoT). That's what, the paper is going to deal. So the principal objective is to
monitoring the thing of parameters from anywhere in the world. The paper is not aimed to integrate entire world
of things right now but dedicated to two fields, medical & small, medium enterprises. In medical field, monitor
the patient through camera interface and patient's moments using WSN interface. And in case of SM Enterprises
monitors, temperature, water level, machine motion detection using WSN and visual through Camera Interface.

Abstract:
The tremendous success of the low-power designs of VLSI circuits over the past 50 years has significant change
in our life style. Integrated circuits are everywhere from computers to automobiles, from cell phones to home
appliances. Domino logic is a CMOS based evolution of the dynamic logic techniques based on either PMOS or
NMOS transistors. Dynamic logic circuits are used for their high performance, but their high noise and
extensive leakage has caused some problems for these circuits. Dynamic CMOS circuits are inherently less
resistant to noise than static CMOS circuits. In this paper we proposed different domino logic styles which
increases performance compared to existing domino logic styles. According to the simulations in cadence
virtuoso 65nm CMOS process, the proposed circuit shows the improvement of up thirty percent compared existing domino logics.

Abstract:
Digital predistortion (DPD) is a baseband signal processing technique that corrects for impairments in RF
power amplifiers (PAs). These impairments cause out-of-band emissions or spectral regrowth and in-band
distortion, which correlate with an increased bit error rate (BER). Wideband signals with a high peak-to-average
ratio, are more susceptible to these unwanted effects. So to reduce these impairments, this paper proposes the
modeling of the digital predistortion for the power amplifier using GSA algorithm.

Abstract:
These days, SMEs pay a lot of attention to concept of Supply Chain Management (SCM) in order to achieve
competitiveness. The logic behind such act is integrating the activities of value creation within any kind of
organizational context. Such integrity would collaborate with managers to accomplish the competitive edge that
they are aiming to achieve. The goal of current research is to identify scopes of a unique construct which is
known as Entrepreneurial Supply Chain Management competency. Therefore, the notions of SCM and
entrepreneurship are being aligned together for evaluating the organizational performance. The outcomes
demonstrate that SCM in fact is a critical issue that can alter the organizational performance, thus, through
consideration of SCM, we should focus on supply chain integration and its impacts on intrapreneurship and
innovation of an organization. In order to be successful in such competitive context, SMEs need to provide
novel competences which are not imitable and to increase their application in supply chain and also to improve their total performance.

Abstract:
The diesel particulate filter (DPF) is a device designed to remove diesel particulate matter or soot from the
exhaust gas of a diesel engine. A series of tests have been performed on a downscaled DPF prototype. This
prototype had high filtration efficiency. Then the next step is to study the soot and ash handling capacity of DPF
system and perform tests on a full-scale prototype. In order to move forward to the next step the functionality of
the filter should be investigated. Moreover, a complete model of flow inside the filter can help parameter
investigation on both downscale and full-scale prototype. Building up a CFD model using fluent which is
capable to simulate the flow through all channels and porous media of the filter plates and tuning the pressure
drop parameters for all steps of filtration from clean filter to dirty one are the main achievements of this project. CFD results have been tuned by using experimental data of filtration tests.

Abstract:
Graphical System Design applications are the fastest spreading one in the field of
industrial environment. Over the decades monitoring of physical parameters in the industrial
environment is made easy with various sensors. Several softwares are used to monitor those physical
parameters. The objective of the work is to monitor the environmental temperature. The sensors that
are used to measure the physical parameters tend to give electrical output either in form of Voltage or
Current. In this paper current output is preferred for temperature conversions rather than the voltage
output as they tend to drop over the transmission line. The current output of Temperature/Humidity
sensor (THD Series) is converted into temperature in degree Celsius. The Real-Time environmental
parameters are acquired from Autonics Temperature/Humidity sensor using NI Compact DAQ
9174(cDAQ). A Graphical approach is developed in LabVIEW platform to monitor the environmental
temperature with the help of a PC.

approach to integrate the knowledge of experts in business intelligent system. The approach presented in this
chapter is targeted towards using ontologies. The use of ontologies in MAS environment enables agent to share
a common set of concept about context, expert user profiles and other domain elements while interacting with
each other. In this paper, we focus especially on the modeling of the system Multi-Agents using O-MaSE
(Organization-based Multiagent Systems Engineering Methodology) and a conceptual diagram of the ontology database.

[Abstract]

[Cite]
Abstract:
One of the major environmental problems faced by the world is management of wastes. Industrial processes
create a wide range of wastewater pollutants; which are not only difficult but costly to treat. Characteristics of
wastewater and level of pollutants vary significantly from industry to industry. To control this problem today
emphasis is laid on waste minimization and revenue generation through by-product and energy recovery.
Pollution prevention focuses on preventing the harmful effect of generated wastewater on the environment,
while waste minimization refers to reducing the volume or toxicity of hazardous wastes by water recycling and
reuse, process modifications and by by-product recovery. Production of ethyl alcohol in distilleries based on
cane sugar molasses constitutes a major industry in Asia and South America. The world's total production of
alcohol from cane molasses is more than13 million m3/annum. The aqueous distillery effluent stream known as
spent wash is a dark brown highly organic effluent and is approximately 12-15 times by volume of the product
alcohol. This highly aqueous, organic soluble containing residue is considered a troublesome and potentially
polluting waste due to its extremely high BOD and COD values. Because of the high concentration of organic
load, distillery spent wash is a potential source of renewable energy. The paper reviews the possibility of anaerobic treatment of the distillery wastewater.

- Closed loop simulation and hardware implementation of a LED
driving circuit from AC source with leakage energy recycling
Lima N.T, Renuka V.S
[Abstract]
[PDF]
[Cite]
Abstract:
This work deals with the design and implementation of an AC to DC LED driving circuit consisting of a buck
boost converter and a flyback converter. A buck boost converter is integrated with a fly back converter by
sharing a single power switch. A recycling path is also provided to recycle the leakage energy stored in
transformer. An EMI filter and a diode bridge rectifier is also included in this converter topology, EMI filter is
used to eliminate high frequency current harmonics at the input line. Diode bridge rectifier is used to convert
AC source voltage to DC voltage. The control of this single switch is done by using DSPIC 30F2010.This
converter has simple structure, low cost, and ease of control as well. In this way, the developed converter can
provide high PF and low total harmonic distortion.
The detailed circuit operations and analysis are provided. The theoretical studies and analysis are tested by a
prototype of 16-W LED driver with a switching frequency of 60 kHz and also a closed loop simulation is done
in MATLAB simulink. The developed converter has maximum power factor of 0.96 and total harmonic
distortion of 10.54%
Keywords:Total harmonic distortion (THD), power factor correction (PFC), Leakage energy recycling.

Abstract:
Energy consumption of a cold storage was measured for different storage temperatures. Suction temperature and
pressure temperature of the compressor and working time of the compressor were determined to reach
evaporator setup temperatures. An axial fan located back of the evaporator was used to distribute the cooled air
into the cold store. An electrical heater was used to defrost. The compressor suction temperature of ammonia
vapour variedbetween273K–271Kand 305K–308K respectively. Compressor suction pressure(p1)=3.5 Kg/cm

Abstract:
Multilevel inverter equipment has developed recently as a very important alternative in the area of high power
medium voltage energy control.in multilevel inverter is the most important topologies like diode clamped
inverter (neutral point clamped),capacitor clamped(flying capacitor) and cascaded multi cell with separate dc
sources. Multilevel inverters are used in high voltage and high power applications with less harmonic contents.
This paper proposes a software implementation for neutral point clamped (NPC) three level voltage source
inverter using space vector pulse width modulation (SVPWM) techniques. The inverter feeds an electrical
system which is controlled by field oriented control (FOC).The improvement of the control technique is
achieved using intelligence techniques. The operation of the electrical system is verified in steady state and
transient state responses. This software implementation is performed by using matlab/Simulink software. This
paper gives comparison between SVPWM three phase three level with neutral point clamped and without
neutral point clamped. Finally, the comparative study of different techniques was implemented.
Keywords:Vector control, Neutral point clamped three level inverter, Space vector pulse width modulation,

- Ground water distillation by basin type solar still for different
basin water depth under the climatic condition of Rewa

Abstract:
Adequate quality and reliability of drinking water supply is a fundamental need. Without potable water or
drinking water (less than about 500 ppm of salt) human life is not possible. Only 1% of Earth's water is in a
fresh, liquid state, and nearly all of this is polluted by both diseases and toxic chemicals. For this reason,
purification of water supplies is extremely important.
Keeping these things in mind, we have devised a model which will convert the saline ground water into pure
and potable water using the renewable source of energy (i.e. solar energy). Solar energy is an abundant, never
lasting, and available on site and pollution free energy.Solar Energy is freely available and can be used as a very
cheap option to convert saline ground Water through Solar Distillation, by using Solar Stills. The conventional
single basin and single slop Passive Solar Still can be used to purify water but the main problem is that the per
square meter distillate output is less. So it is need to modify the design of solar still for high output of solar
distillate
Solar still is easy to construct, can be done by local people from locally available materials, simple in
operation by unskilled Personnel, no hard maintenance requirements and almost no operation cost. Simplest
basin type models of solar still in earlier days, researchers have progressed a lot to increase its efficiency.
Suitable modification of solar still can produce high output using minimum areas of land and even in cloudy
days. Experimental study is done at Rewa M.P. on two different basin water depth solar stills. Low water depth
solar water still is produced more distillate than high water depth still by the experiment.
Keywords:Solar still, saline Water, Evaporation, Basin Water and Solar Distillation.

Abstract:
Since aluminium alloy is a well-known light alloys to use in aerospace and automotive industries. Therefore, a
new method, so far little known in metal forming industries, is the friction stir processing of surface layers.
Friction stir processing (FSP) is an emerging surface engineering solid-state technology which provides the
ability to thermomechnically process selective locations on the materials surface and to enhance specific
properties to some considerable depth. However, from a practical point of view it is important to determine the
impact of FSP conditions, therefore, a tool rotation speed, travel rate, pressure force as well as the shape and
type of tool on the moment acting to heat generated in the stirring area. The heat generated in the area being
processed and the level of plastic strain are factors having a decisive effect on microsturctural changes, and,
consequently, on the mechanical and functional properties of newly formed areas. In this phenomena that the
main FSP features have been investigated through OM (optical microscopy), SEM (scanning electron
microscopy), FESEM (field emission scanning electron microscopy), TEM (transmission electron microscopy)
and mechanical properties. Moreover, aluminium alloy being an age-hardening response to evaluated through
Vicker's hardness measurement a typical characterisation at present task. The research of the FSP of surface
layers, so far has been focused mainly on the metallurgical analysis of microsturctural changes in modified
aluminium alloys.
