Modelling And Analysis Of Metal Matrix Composite Of
Connecting Rod By Finite Element Analysis
B. Velliyangiri, S. Arun, S. Azarutheen, P. Jegadeesh
Abstract — Composite materials are now a days widely used in
the engineering field. The general characteristics possessed by
the composite materials are greatly found to be the reason for
using it in the automotive applications. The objective of the
project is to design and analysis the stress and strain of metal
matrix composite (MMC) connecting rod. The connecting rods
are commonly used in the IC engines and are forced to millions
of varying stress cycles leading to fatigue failure. But the MMC
connecting rods are lighter and may offer better compressive
strength, stiffness when compared to conventional connecting
rod and it's design still represents a major technical challenge. In
this project both the standard steel alloy and composite
connecting rods are modelled and analysed using SolidWorks
2016. A comparative study was undertaken to predict the
structural behaviour of connecting rods using three dimensional
finite element stress, and is determined for the most cost effective
modelling and analysis approach. The finite element results
proves that the performance is similar as that of standard steel
connecting rod. The stress and fatigue analysis of the MMC
connecting rods is observed to be better than that of the standard
connecting rod.

Design and Analysis of Internal Expanding Drum Brake
with Collet & Wedge Mechanism
M. Senthil Prabhu, M.Vinoth Kumar, C.Navaneethan, S.Sathish, N.Vivekanandan
Abstract—The drum brake uses friction caused by a set
of shoes or pads that press outward against a rotating cylindershaped
part called a brake drum. When shoes press on the inner
surface of the drum the braking occurs. In cam operated brake
the intensity of pressure acting in the contact area between the
drum and the pad is low in the portion that is nearer to the pivot
end. This also results in the excessive wear at the portion of a
friction pad nearer to the cam end. To overcome this drawback,
we have used collet and wedge for equal expansion of brake shoe
with more area of frictional contact which provides equal
intensity of pressure to the brake drum. This results in the better
braking efficiency.

B. Velliyangiri, S. Santhoshkumar, M. Sasidhar, N. Srinivasan, T. Vinesh kumar
Abstract— Bio composite is a material produced by a matrix and a
reinforcement of natural fibers like Jute, Coir, Sisal, Pineapple,
Ramie, wicker, Banana and Bagasse, etc. Such natural fibers
composites are low-cost fibers with high specific property, low
density and green. The development of sophisticated bio composite
materials made is increasing worldwide. It will be an another way
to build up the bio composites which can be particularly used for
daily needs of common people whether it is house embrace
furniture, house, fencing, deck, floor covering, and light weight car
parts or sports equipments. This effort to develop a bio composite
material with improved performance for global applications is a
continuous ongoing process. Thousands of tons bagasse is created
but most of their wastes do not have any useful utilization. This
bagasse waste can be used to set up fiber reinforced polymer
composites for commercial use. This work discusses the
development of bagasse fiber reinforced polymer composite, types
of matrix, processing methods, and any alteration of the fiber and

Influence of Extreme Temperature on Electricity
Demand in Madhya Pradesh (India)
Akanksha Dubey, Dr. A. K. Sharma
Abstract—The climate is defined as ‘the general or
average weather conditions of a certain region,
including temperature, rainfall, and wind’. The earth’s
climate is most affected by latitude, the tilt of the
Earth's axis, the movements of the Earth's wind belts,
and the difference in temperatures of land and sea, and
topography. Human activity, especially relating to
actions relating to the depletion of the ozone layer, is
also an important factor. Urban centers heavily depend
upon electricity for their existence, with increase in
temperature electricity demand for space cooling also
increases. Climate Change induced temperature rise
also affect electrical generation at power plants. Due to
excessive cooling demand many cities in India has to
overdraw the electrical power from the grid, while the
other not so important has to bear the power cuts due to
increased demand by others. Urban areas are
continuously growing larger creating huge demand of
electricity for their smooth functioning; Rapid
urbanization and improved lifestyle also adds further
increase in the electrical demand of the city. This study
attempts to improve upon an existing forecasting model
indicating a quadratic Relationship between
temperature and peak electricity demand whereby peak
electricity load increases exponentially with increasing
temperature based on previous analysis.

Opinion Mining Using Polarity Classification Algorithm
K.Sandhya, V.Lavanya Rani, P.Padma Kumari, U.Mounika
Abstract—Sentiment analysis is a broad research area in
academic as well as business field. The term sentiment refers to
the feelings or opinion of the person towards some particular
domain. Hence it is also known as opinion mining. It leads to the
subjective impressions towards the domain, not facts. It can be
expressed in terms of polarity, reviews or previously by thumbs
up and down to denote positive and negative sentiments
respectively. Sentiments can be analyzed using Natural Language
Processing(NLP), statistics or machine learning techniques. The
primary issues in previous techniques are classification accuracy,
data sparsity and sarcasm, as they incorrectly classify most of the
feeds with a very high percentage of feeds incorrectly classified
as neutral. To overcome this we propose an algorithm called
Polarity Classification Algorithm for feeds classification based on
a hybrid approach. The proposed method includes various preprocessing
steps before feeding the text to the classifier.
Experimental results show that the proposed technique
overcomes the previous limitations and achieves higher accuracy
when compared to similar techniques.

Identification of Suitable Parameters for Predicting Handoff
in Real Time Mobile Network Technologies
Aditi Singh, Neeta Nathani
Abstract—Future wireless networks will consist of multiple
heterogeneous access technologies such as Universal Mobile
Telecommunications Service (UMTS), Global System for Mobile
Communication (GSM), Long Term Evolution (LTE) and
Worldwide Interoperability for Microwave Access (Wi-Max).
The main challenge in these networks is to provide users with a
wide range of services across different radio access technologies
through a single mobile terminal. The mobile users are
demanding access to the wireless networks at anytime and
anywhere. To ensure the service continuity and to maintain the
promising Quality of Service (QoS), the decision regarding
handoff is to be taken appropriately. The most common criteria
for handoff is the Received S ignal S trength (RS S ). Now a day’s
integration of different wireless access technologies has become
more important so that the user is made available to get access
without any discontinuity. In such integrated environment to
provide seamless mobility, Vertical Handoff (VHO) is one of the
major issues which need to be addressed for providing better
QoS. The vertical HO scenario introduces issues related to QoS
which affects the connections as well as the applications. This
paper identifies different parameters which are responsible for
a fruitful handoff process by comparing handoffs in different
mobile networks like UMTS, GSM, WiMAX, and LTE. The
paper also discusses about the path traversed by the HO
decision process and find out the parameters which are useful to
make accurate HO decision.

Audio Denoising Algorithm by Adaptive Block
Thresholding using Short Time Fourier Transform
Shivam Tiwari, Rashika Gupta, Ravimohan
Abstract—In this paper, an adaptive bock algorithm with
modified threshold using STFT for denoising of audio
signals is proposed. The signal is first segmented into
multiple blocks depending upon the minimum mean square
criteria in each block, and then thresholding methods are
applied for each block. All the obtained blocks after
denoising of individual block are then concatenated in order
to get the denoised signal. The Short Time Fourier
Transform provides more coefficients than the Discrete
Wavelet Transform (DWT), representing additional timefrequency
details of the signal. STFT gives more degree of
freedom in terms of time-frequency resolution of audio
signals. When an audio signal corrupted with Additive
White Gaussian Noise (AWGN) is processed by using this
algorithm, we obtained higher Signal to Noise Ratio (SNR).
Hence, the proposed algorithm out-performs the other
algorithms. Also the obtained denoised signal with this
algorithm is close to the original signal.

Compressibility Behaviour of Black Cotton Soil
Admixed With Lime and Rice-Husk Ash
Parimal Jha, Nisheet Tiwari
Abstract—Black cotton soil covers about one-fifth of
the area of our country. Owing to its undesirable
engineering properties such as high swelling and
shrinkage, the soil is not good either as foundation or
embankment material. To make the best use of black
cotton soil, its properties are to be modified to suit the
requirements in any specific case by means of
stabilization. Therefore, it is necessary to properly
choose the stabilizer through careful investigation to
improve the strength, compressibility and
permeability characteristics. At the same time, the
economics of the process of the stabilization should
also be considered. In this paper the results obtained
by studying the compressibility behaviour of black
cotton soil admixed with lime and rice-husk ash is
presented. For the purpose of comparison similar
studies have been carried out with admixtures such as
lime and rice-husk separately.

Review on Self Compacting Concrete by Using
Mineral Additives
Hemant Sharma, Nisheet Tiwari
Abstract—Self compacting concrete (SCC) flows into
place Fresh self-compacting concrete and around
obstructions under its own weight. Self-compacting
concrete decreases construction time, labour and
equipment uses on construction,, and helps in
achieving use without applying vibration in congested
reinforced concrete structures characterized by
difficult casting conditions. However, because it
usually requires a larger content of binder and
chemical admixtures compared to ordinary concrete,
its material cost is generally 20–50% higher, which
has been a major hindrance to a wider
implementation of its use. The fresh concrete
properties and compressive strength at 1, 7 and 28
days of such SCC mixtures were measured. The
parameters considered in the study were the contents
of cement, water- cement ratio ,Fly ash, Micro silica
& Metakaolin. The responses of concrete are
recorded from Slump−flow test, L−box, U-box and
V−funnel.

the purpose of data transmission between two
controlling units through WSN without collision.
RTOS is used here to assign the priorities. The values
are sent in the form of packets during specific time; in
this transmission collision may occur to overcome this
Wireless HART (Highway Addressable Remote
Transducer) is used. This paper is implemented in two
section as prototype. First section runs with RTOS and
LPC2148 as master node and another as normal data
acquisition node to which sensor are connected. Second
section contains a controller. Communication between
two nodes is accomplished through wireless HART.
The basic view of this technique is to reduce the
possibility of collision and thus increase the
communication reliability. The sensing parameters can
be displayed as graph in software Implementation. To
do this, all the nodes must be synchronized precisely.
Also, the stack designer must guarantee that the node
can finish everything within the timeslot. It offers
benefits in terms of product life cycle, safety, system
integration complexity, performance scalability.

Privacy Preserving For Scalable and Efficient for Dynamic
Audit
M.Suganya, S.Dhanalakshmi
Abstract—Cloud computing consists a collection of computers and
servers that are publicly accessible via the Internet. User accesses
the data’s and will pay as per user basis. Cloud computing has
four essential characteristics: elasticity and the ability to scale up
and down, self-service provisioning and automatic
reprovisioning, application programming interfaces (APIs),
billing and metering of service usage in a pay-as-you-go model.
While Cloud Computing makes these advantages more appealing
than ever, it also brings new and challenging security threats
towards users‟ outsourced data. Data integrity and storage
efficiency are two important requirements for cloud storage.
Proof of Retrievability (POR) and Proof of Data Possession
(PDP) techniques assure data integrity for cloud storage. Proof of
Ownership (POW) improves storage efficiency by securely
removing unnecessarily duplicated data on the storage server.
The cloud storage service (CSS) relieves the burden for storage
management and maintenance. Fragment Structure, random
sampling and index table is used to construct the Audit service.
These techniques are supported provable updates to cloud
outsourced data. The third party auditing allow to save time and
computation resources with reduced online burden of the user.
In this work, a method based on Probabilistic query and periodic
verification for improving the performance of audit services and
also audit system verifies the integrity.

Remote Access TrojanA New Method for Forecasting Pulses Productivity
Data Based on Fuzzy Time Series with Higher
Forecast Accuracy Rate
B. Vinoth, A. Rajarathinam, S. Ranjethkumar
Abstract—The time-series models have been used to make
predictions in whether forecasting, agriculture forecasting,
academic enrollments, etc. Reference [7] introduced the
concept the concept of fuzzy time series in 1993. Over the
past 20 years, many fuzzy time series methods have been
proposed for forecasting enrollments. These methods
mainly focus on three factors, namely, the universe of
discourse, partition of discourse and the defuzzification
method. These methods have either used pulses
productivity data or difference of productivity data or
percentage change as the universe of discourse. And either
used frequency density based portioning or ratio-based
portioning as the partition of discourse. The main issue in
forecasting is in improving accuracy. But the forecasting
accuracy rate of the existing methods is not good enough.
This paper proposed a method based on fuzzy time series,
which gives the higher forecasting accuracy rate than the
existing methods. The proposed method used the
percentage change as the universe of discourse; mean
based partitioning as the partition of discourse and
proposed method for defuzzification. To illustrate the
forecasting process, the pulses productivity data of Tamil
Nadu is used.

Differential Evolution for Voltage Improvement
Ekta Pandey, A.K.Wadwani
Abstract—Economic load dispatch (ELD) is the method of
allocation generation from the present generation units in
such a manner to fulfill the demand of load and satisfied
constraints to minimized total generation price of power
plant. Reactive power plays a very important role in power
system. In any power system when reactive power absorbed
more or less than reactive power generated, then voltage of
the system decreases or increases from normal operating
value. To obtain the demand at minimum cost while
satisfying the constraints for easy and simplicity, the cost
function for each unit in economic dispatch problems are
approximately shown by a single quadratic functions and is
solved using mathematical programming techniques. ELD
has the objective of generation allocation to the power unit
generators in such a manner that the total fuel cost is
minimized and all operating constraints are satisfied
reactive power dispatch (RPD) is most important role in
the operation and control of power system. This paper
presents a differential evolution (DE) based technique for
solving optional reactive power dispatch with voltage
improvement in power system the monitoring technology
for voltage improvement on the L- index of load buses of
power system. The main aim is to minimize the real
powerless subjected to limits on generator reactive and
real power outputs, transformer taps, bus voltages and
shunt power control devices like SVCS The proposed
algorithm applied to IEEE. 30 bus system to determine the
optional reactive power control variables under safe
voltage satiability limit and it is very suitable for this task
to a large extent the optional reactive power allocation
gives the results using differential evolution are compared

Applications of Automation Techniques in Smart Grid
Technologies
Sushil Chaudhary
Abstract—The terms smart grid, Intelligent Grid, and secure smart
grid are being used today to describe technologies that
automatically and rapidly isolate faults, restore power, monitor
demand, and maintain and restore stability for more reliable
generation, transmission, and delivery of electric power. This
paper focuses on distribution-level protection and automation
techniques illustrated with real-world, case study examples.
Smart distribution automation not only reacts to maintain or
restore stability but also evaluates all available mitigations to use
“best choice automation.” A simple example includes evaluating
pre- event demand and supply at all points on the system. Using
this information and knowledge to predict near-term demand
profile changes leads to a best choice reconfiguration strategy.
This creates a solution that mitigates the fault or event and
provides electricity free of sags, spikes, disturbances, and
interruptions.

Speed Control of Induction Motor Using Vector
Controlled Technique Using MRAS
Jyoti Baghel
Abstract—To implement the vector control technique, the motor
speed information is required. Infrared Tacho-meters,
resolvers or incremental encoders are used to detect the speed.
These sensors require careful mounting and alignment and
special attention is required with electrical noises. Speed sensor
requires additional space for mounting and maintenance and
hence increases the cost and the size of the drive system .These
problems are decreased by speed sensor less vector control by
using model reference adaptive system(MRAS). Model
reference adaptive system is a speed estimation method having
two models namely reference and adaptive model .The error
between two models determines induction motor speed. This
paper proposes a Model Reference Adaptive System (MRAS)
for estimation of speed of induction motor. An Induction motor
is developed in stationary reference frame and Space Vector
Pulse Width Modulation (SVPWM) is used for inverter design.
PI controllers are designed controlling for this purpose. It has
good tracking and attains steady state response very quickly
which is shown in simulation results by using
MATLAB7.8/SIMULINK.

Review on High Performance Median Filter for Salt and
Pepper Noise Removal
Antima Bajpai, Shweta Agrawal, Prashant Badal
Abstract—As the noise may introduced anywhere within
image, a filter is the essential part of the image processing units.
The noise may corrupt the desired signal which may result in
degradation in quality of the image. Among the different noises,
the salt and pepper noise is also the frequently occurred noise
within the image due to transmission error. In order to
eliminate the effect of noise within the image, a special filter
called median filter is used. As the noise density increases, the
conventional median filter fails to provide noise-free image.
Therefore, different algorithm that uses some decision to
reduce the salt and pepper noise is proposed in the literature.
This paper provides a comprehensive literature review on the
different median filter algorithm and architectures.

World, however, existing laws are likely to be unenforceable
against such crimes. This lack of legal protection means that
businesses and governments must rely solely on technical
measures to protect themselves from those who would steal, deny
access to, or destroy valuable information. Cyber attacks can
come from internal networks, the Internet, or other private or
public systems. In this manuscript we deal with the survey

Mining Suspicious Messages in Online Forums
Priyanka, Poorani, Bhavani, Kamalameena, Hariharan
Abstract—Now-a-days there is an increasing dependency on
web applications, ranging from individuals to large
organizations. The security motivation of web application
especially online social network is a great concern. Therefore
in this paper a system is proposed which is an automated
system, called Filtered Wall (FW), able to filter unwanted
messages from OSN user walls. We exploit Machine Learning
(ML) text categorization techniques to automatically assign
with each short text message a set of categories based on its
content. The major efforts in building a robust short text
classifier (STC) are concentrated in the extraction and
selection of a set of characterizing and discriminate features.
The solutions investigated in this paper are an extension of
those adopted in a previous work by us from whom we inherit
the learning model and the elicitation procedure for
generating reclassified data. The original set of features,
derived from endogenous properties of short texts, is enlarged
here including exogenous knowledge related to the context
from which the messages originate. In addition, the system
provides the support for user-defined Blacklists (BLs), that is,
lists of users that are temporarily prevented to post any kind
of messages on a user wall.

Image Segmentation Using K-means Algorithm
Vivek Barwat, Rutesh Lonkar
Abstract—Clustering performance of the K-means greatly relies
upon the correctness of the initial centroids. Usually the initial
centroids for the K-means clustering are determined randomly
so that the determined centroids may reach the nearest local
minima, not the global optimum. This paper proposes a new
approach to optimizing the designation of initial centroids for Kmeans
clustering. This approach is inspired by the thought
process of determining a set of pillars’ locations in order to make
a stable house or building. We consider the pillars’ placement
which should be located as far as possible from each other to
withstand against the pressure distribution of a roof, as identical
to the number of centroids amongst the data distribution.
Therefore, our proposed approach in this paper designates
positions of initial centroids by using the farthest accumulated
distance between them. First, the accumulated distance metric
between all data points and their grand mean is created. The first
initial centroid which has maximum accumulated distance metric
is selected from the data points. The next initial centroids are
designated by modifying the accumulated distance metric
between each data point and all previous initial centroids, and
then, a data point which has the maximum distance is selected as
a new initial centroid. This iterative process is needed so that all
the initial centroids are designated. This approach also has a
mechanism to avoid outlier data being chosen as the initial
centroids. The experimental results show effectiveness of the
proposed algorithm for improving the clustering results of Kmeans
clustering.

Statistical Analysis of Heat Transfer and Fluid Flow
Features of Solar Air Heater
Rajwansh Pandit, Pankaj k. Pal, Ravi Vishwakarma
Abstract—The application of artificial roughness in the form of
fine wires or ribs of different geometry on the heat transfer
surface has been recommended to increase the heat transfer
coefficient by several investigators. The use of artificial
roughness on the underside of the absorber plate disturbs the
viscous sub-layer of the flowing medium. It is well known that in
a turbulent flow a sub-layer exists in the flow in addition to the
turbulent core. The purpose of the artificial roughness is to make
the flow turbulent adjacent to the wall in the sub-layer region.
The present work was undertaken with the objectives of
extensive investigation on the 90° shaped ribs as artificial
roughness on the surface of duct. Experimental setup for heat
transfer and pressure loss has been design and developed. Data
were collected for local heat transfer and pressure loss of these
artificially roughened ducts. Results of artificially roughened
duct have been compared with those of a smooth duct under
similar flow condition to determine heat transfer and friction
factor..

Stereo pair Image Compression process using the effective
Extended Block Truncation Coding Algorithm
Dr.T.Ramaprabha
Abstract—Stereopsis is the ability to perceive three
dimensions by integrating two slightly different views of the
same scene. A stereo image is produced by taking
photographs of the identical scene from two slightly
different positions. The distance between these positions is
called the stereo base. Many cameras have the ability to
stereoscopically image by sequentially taking two images.
Stereo images provide an improved sense of presence, and
have been found to be operationally useful in
responsibilities requiring remote manipulation or judgment
of spatial relationships. A stereo system with a single leftright
pair needs twice the raw data as a monoscopic imaging
system. As a result there has been increasing attention given
to image compression methods specialized to stereo pairs. In
the general concept of stereo image compression method,
first compress the reference (left image) image only, after
that the block matching algorithm is applied between left
and right image to identify the disparity values and they are
encoded separately rather than compressing the whole right
image. In this paper I wish to illustrate the effectiveness of
stereo pair image compression Algorithm using Extended
Block Truncation Coding with higher image quality after
decompression.

VLSI Implementation of A Novel Low Complexity Image
Scalar Architecture
Nitin Singh, Shweta Agrawal
Abstract—The modern portable devices such as smart phones
have been employing huge number of image/video
applications in recent years. This results in exponential rise in
the design complexity of these devices. Moreover, the
advancement in the VLSI technology with nano-scale
transistors dimensions further increases the complexity of
these devices. The highly complex devices consume significant
amount of energy while processing the signal. Further, the
cost of the device increases with increasing complexity.
Therefore low complexity architecture is the prime
requirement. In several image processing applications image
scaling is the commonly used operation to fit the image into
the device display having different sizes. In several
applications such as medical imaging, image scalar is
commonly employed in the medical devices to see the image
capture with different resolution device. This paper proposed
low complexity image scalar and then design is implemented
and evaluated. The simulation results show that the proposed
image scalar reduces area by 12% and delay by 19.95% over
the existing well-known architecture.

Abstract—Big Data is a collection of a huge and complex data
that it becomes extremely tideous to capture, store, process,
retrieve and analyze it with the help of on Relational database
management tools or traditional data processing techniques. To
store and process such a big data hadoop technology is used.
Hadoop is an open source framework that allows to store and
process big data in distributed environment across clusters of
computers using simple programming models. It is intended to
scale up from single server to thousands of machines, each
offering local computations and storage. In this paper, we
propose incremental MapReduce, the most used framework for
mining bigdata. Incremental MapReduce 1) performs key-value
pair level incremental processing, 2) supports iterative
computation, which is widely used in data mining applications.
That means incremental MapReduce processes big data in a less
time and stores it in a more optimized form.

using CFD
Pankaj k. Pal, Rajwansh Pandit, Ravi Vishwakarma
Abstract—The present investigation is concerned with evaluating
heat transfer and friction characteristics of an artificial roughed
solar duct using combination of rough surface on various
relative roughness height and range of parameter studied are
Reynolds number from 3000-14000. A computational analysis of
heat transfer and flow characteristics with artificial roughness in
the form of different types of ribs, heated wall of rectangular
duct for turbulent flow has been carried out with k-e turbulence
model is selected by comparing the predictions of different
turbulence models with experimental results available in
literature. This study evaluates, heat transfer and fluid flow
behavior in a rectangular duct with square roughened ribs
mounted on one of the principal wall (solar plate) by
computational fluid dynamics software ANSYS (Fluent 6.3.26
Solver). In this study, The Reynolds-Averaged Navier–Stokes
analysis is used as a numerical technique and the k-e model with
near-wall treatment as a turbulent model. The results predicts a
significant enhancement of heat transfer in comparison to that of
for a smooth surface with different e/Dh. The performance
evaluation in Terms of thermo hydraulic performance has been
carried out for various value of Reynolds number for some
selected artificial roughness geometries, in the absorber plate of
solar air heater duct. Three roughness geometries as per the
order of relative roughness height (e/Dh) 0.0471, 0.078, 0.083 are
used to create turbulence, and a smooth plate to compare the
result of roughened plates. The range of Reynolds number is
3000 to 14000, Relative Roughness height (e/Dh) .0471mm,
.078mm, .083mm Rib and Heat flux 800 W /m2. The Result has
been compared with smooth duct under similar flow and
boundary condition. The co-relation for heat transfer and
friction factor developed by respective investigators has used to
calculate the thermo hydraulic performance. It is found that
artificial roughness on absorber surface effectively increases the
thermo hydraulic performance and friction factor and efficiency
in comparison to smooth surface.

Multiparty Access Control for Image Sharing in
Facebook
T.Sivaranjini, S.Kavitha
Abstract—Online Social Networking (OSN) has
experienced a tremendous growth in recent years.
OSN has millions of users spread throughout the
world. OSN mainly relies on business networking.
The networking is done for different purpose
depending on the user’s interest. OSN allows people
communication between family and friends
throughout the network. Though this OSN establishes
many networking facilities, it also raises security and
privacy issues. The proof of concept Facebook is
taken and the users of Facebook are restricted to
share their image in their page. When the user shares
the image, the notification is send to their friend list.
Thus when some private data is needed to be shared
the user is unable to share. There may be some users
who try to hurt others with the comments. This must
be prevented in Social Networks since many people
can view this comments. To overcome these issues the
MultiParty Access Control (MPAC) is used. MPAC
creates a block when sharing image and posting
comments. When the user shares image, the
authorized users are only allowed to view it. A
database is maintained in the system which has the
list of hurting words, when user comments, the
comments are checked with the database and the
comment never be posted when the word is present in
the database. Thus MPAC helps in secure sharing of
images and secure posting of comments.

A Survey on Adaptive Algorithms for Noise Cancellation
in Speech Signals
G.Amjad Khan, Dr.K.E.Sreenivasa Murthy
Abstract—The contamination of a signal of interest by other
undesired signals (noise) is a problem encountered in many
applications. The conventional linear digital filters with fixed
coefficients exhibit a satisfactory performance in extracting the
desired signal when the signal and noise occupy fixed and
separate frequency bands. However, in most applications, the
desired signal has changing characteristics which requires an
update in the filter coefficients for a good performance in the
signal extraction. Since the conventional digital filters with
fixed coefficients do not have the ability to update their
coefficients, adaptive digital filters are used to cancel the noise.
The parameters of adaptive filters are mean square error
(MSE) ,signal to noise ratio(SNR) ,convergence and
computation time ,Misadjustment are the various techniques
which gives the performance of the adaptive filters.

A Review on Use of Metakaolin and OP Concrete
Shashikant Dewangan
Abstract—Concrete is the most commonly used
material for construction. The worldwide production
of cement has greatly increased since 1990.Production
of cement results in a lot of environmental pollution
as it involves the emission of CO2 gas. Supplementary
cementations materials (SCM) are finely ground
solid materials that are used to replace a portion of
the cement in a concrete mixture. These
supplementary materials may be naturally occurring,
manufactured or man- made waste. Various types of
pozzolanic materials that improve cement properties
have been used in cement industry for a long time.
Metakaolin is a dehydroxylated aluminium silicate. It
is an amorphous non crystallized material,
constituted of lamellar particles. From the recent
research works using Metakaolin, it is evident that it
is a very effective pozzolanic material and it
effectively enhances the strength parameters of
concrete. This paper reviews the use of metakaolin as
supplementary cementitious material in concrete. A
detailed literature survey is carried out and presented
here.

aggregate, coarse aggregate and water. Concrete is
normally used in all the types of structure. Use of
concrete is huge and all the structure are made with
this material so availability of this raw material is
reduced day by day so cost and requirement of this
material is increased. Due to this limitation of
availability of natural material we are trying to
partially replaced cement by different waste material
for this we conducted survey of different paper which
gives the idea about effect of different waste material
on properties of concrete. The primary objective of
this study is to select the waste material which gives
proper properties with concrete. This study includes

Comparative Analysis of Wavelet Domain Techniques
for Image Steganography
Paramvir Rathi1 Neeraj, Shalu Garg
Abstract—It is now becoming increasingly well known
that signal and image processing are getting great
improvements in performance by using various wavelet
based methods. In order to achieve better
understanding of wavelet based methods, Haar ,
daubechies, symlet, and Biorthogonal wavelets are
discussed. Image is decomposed into four sub bands
using DWT. Secret image is hidden by alpha blending
technique in the corresponding sub bands of the
original image. During embedding, secret image is
dispersed within the original image depending upon the
alpha value. Extraction of the secret image varies
according to the alpha value.The proposed transforms
are compared using different levels in DWT based
image steganography by using statistical parameters
such as peak-signal-to-noise-ratio (PSNR) and mean
square error (MSE). The experimental results
demonstrate that the watermarks generated with the
proposed algorithm are invisible and the quality of
watermarked image and the recovered image are
improved.

Design and Simulation of Microcode based Built-In Self
Repair for Embedded Memories to Enhance Fault Coverage
Mohammed Arif, Ankita Gupta
Abstract—In recent time, it has been surveyed that the System-on-
Chips (SoCs) are moving from logic dominant chips to memory
dominant chips in order to deal with todays and future
application requirements. These changing of technologies give
rise to new defects and new fault models, for which there is a
need for new algorithms which are defined to detect and
eliminate these new defects. These new fault models are used to
develop new high coverage test and diagnostic algorithms. The
higher the fault detection and localization coverage, the higher
the repair efficiency, hence higher will be the obtained yield.
Memory repair becomes important, since only detecting the
faults is not only sufficient for SoCs. March BLC algorithm is a
newly developed test algorithm which deals with detecting some
recently developed static and dynamic fault models. In order to
use this algorithm new microcode BIST architecture is presented
here which is capable of employing these new algorithms. A
word-oriented BISR array is used to detect the faulty memory
locations and repair those faulty memory locations by routing
them to the redundant array.

Priyanka Agrawal, Mahendra Rai
Abstract—Proposed work is a unique DWT based method for
steganography. The Covering image is divided into four sub
bands using transform technique DWT. Data is been hidden
inside HH, HL and LH sub-bands with a new fix mode of
data hiding process. Proposed work reduces the detectable
distortion in a joint photographic experts group (JPEG) file
during data hiding process, by introducing new region
selection rule. The new region selection rule considers three
factors, i.e., the horizontal difference (HD), vertical
difference (VD) and region size (RS). The JPEG image will
be split into number of blocks and each pixel in it will be
examined to calculate the variations. Depends upon the
variation, the amount of secret information will be hide in an
image. This proposed method of information hiding will help
to solve the security issues in computer networks.

F.X.Edwindeepak, D.Sivapriya
Abstract—The Demand of renewable energy sources for power
production is rising from the period of time. Solar power plants
are play vital role in supplying increased power challenge. PV
array with battery based quasi z source inverter makes more
reliable under PV fluctuations. The energy storage device is
integrated to ZSI topology with no requirement for an extra
charging circuit. This modified system obtains the operating
characteristics from the conventional ZSI, with ability of
operating under low renewable (PV) power conditions. In order
to work below this circumstance, an energy storage device
capable of managing the load demand for a period of time is

To Implement the Frameworks to Reduce the Risks of
Fragmentness & Integrity Issues In M-Commerce through
Virtual Objects (VO)
S.M. Roychoudri, Dr. M. Aramudhan, Dr.K.P.N.V Satyasree, M.Sambasiva Rao
Abstract—The evolution of mobile communication technology has
fostered the development of new mobile multimedia applications in
various domains. One of the most important applications is mobile
commerce (m-commerce), which has an increasing impact in the
life of the citizens, and could represent one of the many
applications that contribute to the market success of the Internet of
Things (IoT). Security and privacy concerns are quite relevant in
m-commerce and IoT to protect financial and personal data of the
citizens. One of the main issues in mobile commerce is how to
ensure the security of the information needed to complete the mcommerce
transaction in a distributed environment with different
security frameworks. We have to consider that the protection of
the m-commerce transactions must also be done to protect the
privacy of the customer. In addition, the information of the mcommerce
transaction can be fragmented in different files in a
distributed m-commerce application, which can undermine the
integrity (another security goal) of the transaction. In this article,
we describe the design ofa m-commerce framework, where these
issues are addressed through a policy based approach, where the
access to the m-commerce transaction is regulated by policies. The
fragmentation and integrity risks are addressed through the
concept of Virtual Objects (VO), which have been defined in the
FP7 iCore project. Policies are associated to VOs and distributed
across the m-commerce applications. This paper describes the
main concepts of VO and the policy based framework and shows
how these concepts are applied to m-commerce in various scenarios
to evaluate their feasibility. We apply and demonstrate the benefits
of the proposed design to specific multimedia use cases of mcommerce
where different domains are involved. Such as mcommerce
system can be seen a basic underlying payment system
for a wide variety of multimedia applications.

Logo Matching and Detection for Document Image
Recognition
Dr.B.B.M.KrishnaKanth
Abstract—Graphics detection and recognition are fundamental
research problems in document image analysis and retrieval.
logo detection and recognition continues to be of great
interest to the document retrieval community as it enables
effective identification of the source of a document. We
contribute, through this paper, to the design of a novel
variation framework able to match and recognize multiple
instances of multiple reference logos in image archives.
Reference logos and test images are seen as constellations of
local features (interest points, regions, etc.) and matched by
minimizing an energy function mixing: 1) a fidelity term that
measures the quality of feature matching, 2) a neighborhood
criterion that captures feature co-occurrence geometry, and
3) a regularization term that controls the smoothness of the
matching solution. We also introduce a detection/recognition
procedure and study its theoretical consistency.

Effect of Metal Hydroxide Nanoparticles against different
isolated Bacterial Species
Akhilesh Kumar, Supriya Mishra, Madhulika Singh, Sujeet Kr. Singh
Abstract—A nanoparticle (or nano-powder or nano-crystal or
nano-cluster or nano-material) is a microscopic particle with at
least 1D less than 100nm.A variety of metal hydroxide
nanoparticles have shown success for use as vehicles for drug
delivery, targeted gene delivery, and tumour imaging. This is
typically because nanoparticles have a greater surface area per
weight than larger particles, which cause them to be more
reactive to some other molecules. In the present project work
preparation of metal hydroxide nanoparticles and toxicological
study of it on isolated bacterial species was done. In this study,
Zinc Hydroxide NPs, Iron Hydroxide NPs and Magnesium
Hydroxide NPs were rapidly synthesized from Zinc Nitrate,
Ferric Chloride and Magnesium Chloride respectively. And these
prepared different metal hydroxide nanoparticles were tested for
its antibacterial activity on isolated bacterial species Micrococcus
Leteus and Staphylococcus Aureus, by using agar well diffusion
method. The zone of inhibition was observed and recorded to
determine its antibacterial activity. The inhibition of bacterial
growth was tested for prepared nanoparticles on diluting it, by
MIC test. The term “nanoparticles” means only solitaire
nanoparticles. The maximum growth was inhibited by ferric
hydroxide nanoparticles and minimum growth of bacteria
inhibited by Zinc hydroxide and Magnesium Hydroxide.

A Congestion Avoidance Scheme Based On Buffer
Occupancy
Goree. Narsimhulu, Dr.D. Sreenivasa Rao
Abstract—Recently many prominent web sites face so called
Distributed Denial of Service Attacks (DDoS). DDoS attacks
are a virulent, relatively new type of attack on the
availability of Internet services and resources. To avoid
denigration most of the commercial sites do not expose that
they were attacked that is the biggest challenges of the
researchers. Network congestion caused by DDoS attack can
be managed by AQM (Active queue Management).Random
Early Detection (RED) is one of the most prominent
congestion avoidance schemes in the Internet routers. To
overcome the limitations of the basic RED algorithm,
researchers proposed several variants of RED. For solving
this problem, this paper proposes a new mechanism to
improve RED algorithm, which is named BO-AURED (An
Adaptive RED Algorithm Combined With Buffer
Occupation and upper threshold). By matching router’s
buffer occupation with wq , minth , maxth,Uth and Pmax
parameter settings, to make BOAURED adapt to network
environment variation automatically. Simulation is done in
NS- 2.35 simulator environment. Simulation results show
that our new BO-UARED algorithm gives better performance
than RED and Adaptive RED. Comparisons are done in
terms of total average throughput, total packet drops, and
average packet drops. It will also increase adaptability of
RED.

A Review on Partial Discharge Behavior in High
voltage Equipment
Jayshree Nagdev, Arti Bhandakkar
Abstract—Insulators are very important part of high
voltage power equipment. There are so many types of
insulators are used in high voltage power system to
protect the power equipment like gases, vacuum, solid
& liquid or a combination of these. It is very important
to keep the insulators in a normal or healthy condition
during its operation. Since insulators are always
available in impure form and weak points, voids, cracks
are present inside the insulators and this will create
Partial discharge (PD), which in cause of time reduce
the strength of insulation leading to a total or partial
failure or breakdown of insulation. Therefore detection
of partial discharge is very important task for electrical
engineers to keep the high voltage power equipment in
healthy or normal condition. Modeling of the partial
discharge process allows a better understanding of the
phenomena. In this paper a brief description of PD, PD
mechanism, classification of PD, effect of partial
discharge in insulating system.

Impact of Office Ergonomics on Business
Performance – (In Special Reference to Noida
Region)
Ankit Garg, Vaibhav Garg, Pankaj Dutta
Abstract—In the past few decades, there has been a
strong trend for corporate organizations and
businesses to reconfigure the spaces of their offices in
new ways and models. In addition, the shift towards
more exciting and flexible workplace environment
and the need to meet the diverse and growing
expectations and requirements of different employees
has led to the rise of debates about how and where
productive work is accomplished. In a 2003 survey by
Management Today magazine, virtually all (97 per
cent) of respondents said that they regarded their
place of work as a symbol of whether or not they were
valued by their employer. Office ergonomics have
been recommended by many studies as one of the key
guides to equipping employees at the workplace to
help produce best performance. It is the quality of the
employee’s workplace environment that most impacts
on the level of employee’s motivation and subsequent
performance. How well they engage with the
organization, especially with their immediate
environment, influences to a great extent their error
rate, level of innovation and collaboration with other
employees, absenteeism and, ultimately, how long
they stay in the job Al-Anzi (2009). This study helps
to assess the impact of office ergonomics on business
performance in Noida region; to analyze the office
design, finishes and furnishing at the offices in Noida
region, to assess the impact of office ergonomics in the
design, finishes and furnishing in terms of their
suitability and comfort of the employees; to identify
the impact of office ergonomics on employee health,
safety and security. Here in this study we use
convince sampling and the target sample was from
Noida region. We collect questionnaire by using
questionnaire method and the analysis is done by
using SPSS, correlation analysis and data was
represented by using percentages, frequencies, mean,
and standard deviation. The study demonstrated that
office ergonomics deficiencies at the offices in this
region which includes outdated office design and
décor, inadequate office illumination, un-ergonomic
office furniture, unsuitable office design and décor
have variedly impaired the performance of an
average employee by between 30 to 70 percent. The
study recommends the relocation of the office to a
purpose-built office facility that integrates high
standards of office ergonomics, and companies should
undertake post-occupancy evaluation one year after
occupation of the new office.

Adaptive Fuzzy Logic in TCP/IP Networks using
PID controller
P. Danushapnadeesh, J.R. Thresphine
Abstract—We introduce a novel and robust active
queue management (AQM) scheme based on a fuzzy
controller, called hybrid fuzzy-PID controller. In the
TCP network, AQM is important to regulate the
queue length by passing or dropping the packets at
the intermediate routers. RED, PI, and PID
algorithms have been used for AQM. But these
algorithms show weaknesses in the detection and
control of congestion under dynamically changing
network situations. In this paper a novel Fuzzybased
proportional-integral derivative (PID)
controller, which acts as an active queue manager
(AQM) for Internet routers, is proposed. These
controllers are used to reduce packet loss and
improve network utilization in TCP/IP networks. A
new hybrid controller is proposed and compared with
traditional RED based controller. Simulations are
carried out to demonstrate the effectiveness of the
proposed method and show that, the new hybrid
fuzzy PID controller provides better performance
than random early detection (RED) and PID
controllers.

Survey on Adaptive Fuzzy Logic in TCP/IP Networks
Using PID controller
P. Danushapnadeesh, J.R. Thresphine
Abstract—This paper presents a survey on active queue
management(AQM) scheme, Fuzzy Explicit Marking
(FEM), supporting explicit congestion notification (ECN),
to provide congestion control in TCP/IP best-effort
networksusing a fuzzy logic control approach. While many
AQMmechanisms have recently been proposed, these require
careful configuration of non-intuitive control parameters, and
show weaknesses to detect and control congestion under
dynamic traffic changes, and a slow response to regulate
queues. The proposed fuzzy logic approach for congestion
control allows the use of linguistic knowledge to capture the
dynamics of nonlinear probability marking functions, uses
multiple inputs to capture the (dynamic) state of the
network more accurately, and can offer effective
implementation. A simulation study over a wide range of
traffic conditions shows that the FEM controller outperforms
a number of representative AQM schemes in terms of queue
fluctuations and delays, packet losses, and link utilization

A Novel algorithm for document search in unstructured
Network
Kanthimathi S, Gayathri RU VA
Abstract—Client-Server architecture is a network architecture
in which each node on the network is either a client or a server.
Each client is connected to a centrally located dedicated
computer called server. The server must be fast and should
have more storage capacity to contain all the data that needs to
be shared to the clients. In peer-to-peer network, computers
are connected individually such that there is no dedicated
server. All the computers are equal, termed as peers. Each
node on the network has the capability to share data and
resources with other nodes. In another words there is no
central authority that determines the network's resources
sharing policy. Each user has the right to decide what he would
or would not like to share. Each can act as both client and a
server. The Domination set-based search algorithm is analyzed
and the efficiency achieved is compared with the previous
algorithms that existed earlier. More specifically, the various
steps involved in searching, such as construction of a connected
dominating set (CDS) and the associated reduction rules are
studied. Performance results show that the Domination setbased
search algorithm helps in achieving more efficiency, thus
making it suitable for efficient searching of data in Peer-to-
Peer networks in an effective manner.
