Steganography System Using Successive Logical And Operation Of Last Four Bits
Shivani Yadav, Deepak Goyal
Abstract — Steganography is a technique of hiding information in some cover
media i.e. image, text, audio, video . The main purpose of steganography is to
conceal the existence of the message while communicating. In this paper, a new
Steganography technique is presented, implemented and analyzed. The proposed
method uses the 5th, 6th, 7th & 8th bit of pixel value of cover image. The main
idea is to apply successive Logical AND operation on last four bits of pixel
value.

Review Paper on Black
Hole Attack in Manet
Monika Nandal, Deepak Goyal, Pankaj Gupta
Abstract— A mobile ad hoc network (MANET) is a collection of autonomous nodes
that communicate with each other by radio network and maintaining connections in
a decentralized manner. Security remains a major challenge for these networks
due to theirseveral features suchas open medium, dynamic topologies, reliance on
cooperative algorithms, absence of centralized accessing points, and lack of
clear lines of defense. A large number of attacks occur in MANET such as
wormhole attack,blackhole attack,Sybil attack etc. So, protecting the network
layer of a MANET from these malicious attacks is an important and a very
challenging issue. Most of the routing protocols for MANETs are vulnerable to
various types ofattack such as AODV, DSR. Ad hoc on-demand distance vector
routing (AODV) is a very popular routing algorithm. However, it is vulnerable to
thewell-known black hole attack. Blackholeattack , where a malicious node
falsely advertises good paths to a destination node attract the source nodes
during the route discoveryprocess but drops all packets in the data forwarding
phase. This attack becomes more severe when a group of malicious nodescooperate
each other.

Enhanced Security Mechanism to Mitigate Blackhole Attack in MANET
Using Fuzzy Logic
Monika Nandal, Deepak Goyal , Pankaj Gupta
Abstract—A mobile ad hoc network (MANET) is a collection of autonomous nodes
that communicate with each other by radio links and maintaining connections with
each other in a decentralized manner. Security is a major challenge for wireless
networks due to several features such as open medium of communication, dynamic
topology, absence of centralized accessing points etc.[7,10]. In this paper,
Blackhole attack is discussed. A Black hole node[5] is actually a bad node which
seems to promise sender that it will direct the message to the correct receiver,
but in actual it either drops the packets, not try o send the message to proper
destination or disturb the contents stored in packets. So, to protect the
network layer of a MANET from this black hole attack is an important issue. We
try to use fuzzy approach to detect and prevent node to be black hole[4]. Here,
three parameters –throughput, packet loss, packet delay are used to ensure which
neighbor node will be next hop to reach destination We use AODV protocol. While
selecting the next routing node a fuzzy analysis is performed to identify the
maximum throughput node, minimum packet loss and the minimum delay node. The
work generates a new routing path for the communication. The obtained results
show that the proposed approach has improved the overall communication over the
network and reduced the packet loss.

Experimental Investigation Of Thermal Energy Storage Using Spherical Pcm Capsules
K.Jayasimha Reddy , E.Siva Reddy
Abstract— Conventional fossil fuels on one hand are depleting and on the other,
are creating pollution and spoiling the environment and hence the efforts to
utilize various renewable energy sources are to be expedited. In countries like
India, solar energy is a promising alternate source of energy. The major problem
with solar energy is inconsistency between the supply and demand. The method of
Thermal Energy Storage system used in the field of solar energy may fulfill the
gap . TES technique is achieved by means of Sensible Heat Storage (SHS) and
Latent Heat Storage (LHS). Several researchers focused to study and analyze the
heat transfer of TES system using PCM . Phase change in spherical geometry is of
great interest. Good amount of research work has been carried on the
solidification and melting with in spherical enclosures. Spherical shapes
exhibited the best heat released performance among the other investigated
shapes. In the present work it is proposed to study and analyze the solar TES
with PCM encapsulated in spherical geometry. Line focusing concentrating
collector are used under high mass flow rates with continuous circulation. Also
as the part of study, the experiment have been conceived to carry out at
different flow rates of inlet fluid and two types of PCM .

Evaluation Model For Web Service Change Management Based On Business Policy Enforcement
G.Nandhini,P.Inbavalli,T.Halima Begum
Abstract-Today organizations in all industries are increasingly dependent upon
IT and a highly available network to meet their business goals. As customer
expectations is one of the current problems faced by IT enterprises at present,
leading to increasingly complex IT service management systems. Although there
exists many change management issues and solutions, there is no proper support
for efficient change evaluation and monitoring. Present change management works
are done only in the web service interface such as WSDL Web Service Definition
Language and there is no proper support for dynamic nature in them. In order to
provide a flexible environment for the Business Analyst to perform the emergency
changes over the service business logic without the need of IT staff and also to
evaluate changes made, we propose a Finite State Machine based Evaluation Model
for Web Service Runtime Change Management and also a set of change factors to
evaluate runtime changes of web services. Among which we mainly focus on the
factor Business Policy Enforcement which is used for checking whether there is
any policy violation with respect to the changes made. We first define the
various change factors and derived solution is considered as the change measure
for individual change factor.

Using CFD Analysis
M.Govardhana, Dr.B.Veerabhadra Reddy
Abstract─The aim of the paper is to evaluate the drag and lift coefficients of
an Ahmed body. The geometry of Ahmed body is a simplified car used to
investigate the flow analysis in automotive vehicle. CFD simulations are carried
out by dividing the physical domain into small finite volume elements and
numerically solved the governing equations that describe the behavior of the
flow, in which simplified generic land vehicle geometry was used to analyze the
effect of a slanted rear end and the effect of the angle is carried. The
geometry with 25° hatchback angle solid model of the car is developed using
CATIA V5. The modeled car is imported to GAMBIT (version 2.4) where the fluid
flow around the car is given and a tetrahedral mesh is generated. The drag and
lift coefficients are obtained using the FLUENT. The commercially available
FLUENT (version 12.1) has been used in the present analysis with the objective
of obtaining a better flow around the car and lowering the coefficient of drag.

K. Julia Rose Mary, P. Monica, S. Mythili
Abstract - The aim of this paper is to investigate the cost analysis of MX/G1
G2/1 Multiple vacation (MV) Queuing model in Fuzzy environment which helps to
control the queues in different situation. A mathematical Parametric Non-linear
Programming (NLP) method is used to construct the membership function of the
system characteristic of a batch arrival multiple vacation policy queue in which
arrival rate, service rate for vacation period, holding cost, setup cost,
startup cost reward cost are fuzzy numbers. The α-cut and Zadeh’s Extension
Principle[19] are used to transform a fuzzy queue into a family of conventional
crisp queues. By means of membership functions of the system characteristics, a
set of parametric non linear program is developed to calculate the lower and
upper bound of the system characteristics function at α. Thus the membership
functions of the system characteristics are constructed. Numerical example is
also illustrated to check the validity of the proposed model.

A Novel Construction Technique For Designing Of Video Application Using Wireless 4G
G. Naga jyothisree, K.Vasu babu
Abstract— In an OFDM scheme, a large number of orthogonal, overlapping, narrow
band sub-channels or subcarriers, transmitted in parallel, divide the available
transmission bandwidth. The separation of the subcarriers is theoretically
minimal such that there is a very compact spectral utilization. The attraction
of OFDM is mainly due to how the system handles the multipath interference at
the receiver. Multipath generates two effects: frequency selective fading and
inters symbol interference (ISI). The "flatness" perceived by a narrow-band
channel overcomes the former, and modulating at a very low symbol rate, which
makes the symbols much longer than the channel impulse response, diminishes the
latter. Using powerful error correcting codes together with time and frequency
interleaving yields even more robustness against frequency selective fading and
the insertion of an extra guard interval between consecutive OFDM

Optimizing The PTFE Teflon Vortex Tube Parameters Using Taguchi Technique
Prerna S. Kulkarni, Dr. J.W.Bakal
Abstract— Vortex tube is a mechanical device that separates compressed gas into
hot and cold streams. When high pressure air enters into the vortex chamber
through one or more tangential nozzles, a strong vortex flow created which
splits into two regions. The high temperature air near the boundary of the tube
leaves circumferentially through the conical valve where as the air at lower
temperature leaves through the cold orifice. A conical valve is adjusted with
the hand control knob allows for adjusting the volume and temperature of air
coming out from the cold end. There is no maintenance, no mess, no explosion
hazard, no electricity, and no moving parts in using the vortex tube. Vortex
tubes behave in a very predictable and controllable way. The only disadvantage
with the vortex tube is its low coefficient of performance (COP).

Designing an Efficient Routing Protocol for Opportunistic Network
Nikhil Khichariya,Neha Choubey
Abstract— Opportunistic networks are one of the mainly attractive developments
of MANETs. In These networks, movable nodes are enabled to correspond with each
other even if a route linking them not at all exists. In addition, nodes are not
invented to hold or obtain any information about the network topology, which
(instead) is essential in traditional MANET routing protocols. Routes are built
enthusiastically, while communication are route among the dispatcher and the
target(s), and any promising node can opportunistically be use as subsequently
hop, provide it is probable to take the communication quicker to the final
objective. These necessities formulate opportunistic networks a difficult and
hopeful research field. In this Paper, a new steering protocol for
transportation less is predictable that is an enhancement of the obtainable
contagion routing protocol.

A new approach for highly throughput AES encryption method on FPGA
Ashish kumar Agrawal, Santosh Yadav
Abstract— The significance of the security problems is greater in current data
networks than in earlier systems because users are provided with the way to
accomplish very critical operations like banking transfer and sharing of
confidential business data, which require very high levels of protection. Weak
security architectures allow successful eavesdropping (unauthorised attack),
message tampering and modification attacks to occur, with huge consequences for
end companies, users and other departments. The Advance Encryption standard
(AES) block encryption present at the core of the f8 data hiding algorithm and
also the f9 data reconstructing algorithm for Universal data Telecommunications
System networks. The design aim is to enhance the data conversion rate means the
throughput to an appropriate value hence the design can be used as a
cryptographic sub-processor in very high speedy network uses. The work is to
design an optimised solution for secure data communication AES is the standard
encryption technique but proposed work is more optimised solution for the same
when the chip area and encryption time considers as design parameters. Thesis

Video Compression: A New Accordion Based Approach
Ajay Devatwal, Prof. Mahesh Prasad Parsai
Abstract- In this paper, we propose a new strategy to for the improvisation in
the performance of ACC-JPEG. ACC-JPEG is the approach based on the accordion
transform that tends to exploit the both intra and inter frame correlation. The
ACC-JPEG technique compresses the video by reducing the spatial, spectral and
temporal redundancies of the input video. The temporal redundancy is mainly
depending on the co-relation between successive video frames. The accordion
function converts the temporal redundancy into the spatial redundancy, which was
removed using Discrete Cosine Transform (DCT). The accordion based ACC-JPEG
technique is modified by changing the extracted block size used for the
accordion manufacturing.

Efficient Cooperative Cache Replacement Algorithm for Distributed Social Wireless Networks
K. Kiranmai, Y.Leela krishna
Abstract-This paper introduces cooperative caching techniques for tumbling
electronic content provisioning cost in Social Wireless Networks (SWNET).SWNETs
are formed by mobile devices, such as modern cell phones etc. sharing common
takings in electronic content, and actually meeting together in public places.
Electronic object caching in such SWNETs are shown to be able to reduce the
content provisioning cost which depends heavily on the service and price
dependences among various stakeholders including content providers (CP), network
service providers, and End Consumers (EC).This paper develops practical network,
service, and pricing models which are then used for creating two object caching
strategies for reducing content provisioning costs in networks with homogenous
and heterogeneous object demands. The paper develops analytical and simulation
designs for analyzing the proposed caching strategies in the presence of selfish
users that deviate from network-wide cost-optimal policies. It also reports
results from an Android phone based prototype SWNET, validating the presented
analytical and simulation results.

Constitutional Battles On Right To Property
Anukriti Jain
Abstract-The Land Acquisition, Rehabilitation and Resettlement Act, 2013
(earlier Bill, 2011) was passed in the Lok Sabha in September, 2013. It was
passed in view of the various short comings of the Land Acquisition Act, 1984
and due to lack of resettlement and rehabilitation policies. The new Act tries
to fill the lacunae in the previous Act. It tries to solve the dispute of forced
acquisition and compensation which existed in the 1984 Act. This paper analyses
the Act and the major concerns with respect to right to property in the light of
the Constitutional history and development of the Right to property in India.
The highlights includes whether the present Act actually redresses the
resettlement and other grievances of the people. Whether the state now justified
in acquiring the property with its new compensation, resettlement and
rehabilitation policies? Are the justifications enough to be given to the people
while acquiring their property in the name of public interest? Is the scope of
“public purpose” now exhaustive? Would it be better to have right to property as
a fundamental right? What led the Supreme Court to make right to property a
constitutional right? Whether the new Act a consequence of making right to
property a constitutional right or a consequence of its emerging importance as a
fundamental right? All the questions have been dealt with respect to the
development of right to property in the Constitutional law. The key questions
would be dealt in this paper, starting with the present Land Acquisition Act,
2013.

Presence Cloud for Mobile Presence Services in
Social Network Application
Gonchi Shobha, A.Anitha
Abstract—Now a day’s Social networking services on the Internet are growing and
increasing number of people are using these new ways to communicate and share
information. At the same time mobile phones are becoming more powerful and
increasingly offer high speed Internet connectivity. Because of this people
expect these social networking services to be available on their mobile device.
The mobile presence service is maintains each mobile user’s presence
information, such as the current status (online/offline), GPS location and
network address, and also updates the user’s online friends with the information
continually. If the availability updates occur frequently, the enormous number
of messages distributed by presence servers may lead to a scalability problem in
a large-scale mobile presence service. To solve the problem, we propose
efficient and scalable server architecture, called Presence Cloud, which enables
mobile presence services to support large-scale social network applications.
When a mobile user joins a network, Presence Cloud searches for the presence of
his/her friends and notifies them of his/her arrival. Presence Cloud organizes
presence servers into a quorum-based server-to-server architecture for efficient
presence searching. It also leverages a directed search algorithm and a one-hop
caching strategy to achieve small constant search latency. We analyze the
performance of Presence Cloud in terms of the search cost and search
satisfaction level. The search cost is defined as the total number of messages
generated by the presence server when a user arrives; and search satisfaction
level is defined as the time it takes to search for the arriving user’s friend
list. The results of simulations demonstrate that Presence Cloud achieves
performance gains in the search cost without compromising search satisfaction.

Power Quality Improvement In A Single Phase Voltage Controlled Grid Connected To Pv System
A.Kusuma Kumari, M.Bhaskar Reddy
Abstract—This project deals with a single phase Photo Voltaic system with grid
connected voltage control. When Distributed Power Generation System (DPG) is
connected to a low voltage grid then the frequency and voltage of a grid cannot
be controlled by adjusting the active and reactive power independently and also
it is cost effective. To overcome this DPGS are replaced by PV systems where the
shunt controllers are used to compensate small voltage variations which can be
controlled by reactive power injection. The shunt controllers can be used as
static VAR generator for stabilizing and improving voltage profile of power
systems and to compensate current harmonics, unbalanced load current and
improving voltage quality in case of small voltage dips. There the present
topology of PV system adopts a repetitive controller, able to compensate the
selected harmonics. The power provided by the PV panels are controlled by a
recent algorithm know as Maximum Power Point Tracking (MPPT) based on the
incremental conductance method and it has been modified to change the phase
displacement between the converter voltage and the grid voltage, maximizing the
extraction of power from the PV panels and compensation of harmonic distortion
at the Point Of Common Coupling (PCC).

Fuzzy Cost Enabled Multipath Routing With Rough
Set Approach in Mobile Ad Hoc Network
Gomathi.M, Viswanathan.R
Abstract—In this article, we propose on selecting the effective routing paths in Mobile
Ad Hoc Network (MANET) with fuzzy cost using rough set theory. MANET is a
collection of wireless mobile nodes that can dynamically form a network. Many
routing protocols have been existed to find the shortest path using various
resources. Fuzzy and Rough set theory is one of the approach for choosing the
best path with minimal number of resources. The problems with existing methods
are frequent route change with respect to change in topology, congestion as
result of traffic and battery limitations since it’s an infrastructure less
network. So overcome these problems an optimal path management approach called
path vector calculation based on fuzzy and rough set theory addressed. Focus of
this research activity is to justify simpler rules and removes irrelevant
resources for evaluating the best path. An example is also given to illustrate
the efficiency of our proposed method.

Quantification of Short-TE Metabolite Signals in Human Brain at 3T
using QUEST Algorithm and a Simulated Basis Set
Hyeon-Man Baek
Abstract—In vivo short-echo time (TE) proton magnetic resonance spectroscopy (1H-MRS) is
a useful method for quantification of human brain metabolites. To evaluate the
performance of QUEST (quantitation based on quantum estimation) method, a Monte
Carlo study was done using the weighted sum signal. 8 of 10 metabolites had low
Cramer-Rao Lower Bounds (CRLB), but Asp and GABA showed relatively high CRLBs
because these two peaks have lowconcentration, complex multiplets that severely
overlap with other. In in vivo study, QUEST reliably quantified NAA, Cho, Cr
(CRLB < 5%) and somewhat reliably quantified Glu, Glx, and Ins (CRLB = 10-20%)
in the basal ganglia of healthy subjects at 3T. However, GABA, Asp, Gln, GSH and
Tau could not be reliably quantified (CRLB > 30%) at 3T MRI scanner. Therefore,
QUEST method is feasible for in vivo quantification of short-TE metabolite
signals.

Factors Influencing
Purchase Decisions of Durables in Nagaland: An empirical Study
Thangasamy Esakki
Abstract—Universally, consumers buy a variety of products to satisfy their needs and
wants. The buying behaviours of ultimate consumers, as compared with
business/industrial buyers, are more complex and dynamic. More participants,
deliberations, and involvements are required to make sound purchase decisions of
durables as it involves relatively larger cash outlay. Such consumer decision
making processes, at different phases, are influenced by several factors such as
cultural, social, psychological, personal etc. Apart from these factors, the
products‟ multifaceted dimensions do also often influence the final buying
decisions of the consumers. In order to integrate the interests of both the
firms and consumers judiciously, by ensuring maximum satisfaction to consumers
profitably, a study on product-related factors influencing the final buying
decisions becomes the need of the hour. In India, such studies are being
undertaken throughout the country off and on. However, in North Eastern Region,
especially in Nagaland, no such significant studies on this front have been
carried out so far. This crucial element has, thus, become the rationale for the
present study. This paper is an attempt to analyze the factors influencing the
purchase decisions of selected durables viz; Television, Refrigerator, Washing
Machine, Four Wheeler and Furniture in Nagaland, to identify the intensity of
their influence on consumers‟ buying decisions of the durables, and to put
forward suggestive measures to the marketers for designing an apt product mix to
the consumers within the State.

Improvement of Power Quality Using
Transformerless Cascaded STATCOM under
Balanced / Un-Balanced Supply Conditions with
Non- Linear Loads
Mohammad.yaseen,S.Chandra Sekhar
Abstract—The rapid development of power electronics technology provides opportunities to
develop new power equipment to improve the performance of the actual power
systems. STATCOM can provide fast and efficient reactive power support to
maintain power system voltage stability. Based on the cascaded H-bridge
structure, a new STATCOM control strategy under the conditions of unbalanced
loads and asymmetric system voltage is proposed. It proposes a control algorithm
that devotes itself not only to meeting the demand of reactive power but also to
voltage balancing of multiple galvanically isolated and floating dc capacitors.
The control algorithm based on a phase-shifted carrier modulation strategy is
prominent in having no restriction on the cascade number. This control strategy
can be used to both the unbalanced loads and the asymmetric system voltage,
avoiding the over current of negative sequence current and the clusters’ dc-side
voltage unbalance due. The simulation results are obtained using MATLAB/SIMULINK
software.

Phase shifted carrier PWM control technique of
a series parallel switched multilevel dc-link inverter
topology
B. Ramakrishna Singh, Y. Kusumalatha
Abstract—The use of multilevel inverter (MLI) appears to experience an increasing trend
in view of the extensive automation in industries. A good number of MLI
topologies are in use over the past four decades. The variable voltage and
frequency requirements emphasize the need and elaborate the increasing trend of
using multilevel inverters (MLI) in modern drives and utility applications. The
multilevel inverter [MLI] is a promising inverter topology for high voltage and
high power applications. This inverter synthesizes several different levels of
DC voltages to produce a stepped AC output that approaches the pure sine
waveform. The conventional MLI requires more number of switches as the level
increases and also switching losses and cost also increases. In order to address
the above concerns, this paper presents a new series parallel switched
multilevel dc-link inverter (SPMLDCLI) topology with reduced number of switches
for a particular voltage level. By appropriately choosing a ratio for the
voltage sources (V0: Vn) and connecting them in series/parallel, a particular
level in the output voltage is generated and hence the name SPSMLDCLI. Finally
the proposed technology is verified by using MATLAB/SIMULINK software and the
corresponding results are presented.

Simulation of Series, Parallel Configured 7 level
Switched Capacitor Inverter with Inductive Load
Dosapati.Firoj Kumar, S.Chandra Sekhar
Abstract— Switched capacitor converters have become more common in recent years.
A multilevel inverter with a limited number of switching devices is proposed.
That inverter consists of an H-bridge and an inverter which outputs of
multilevel voltage by switching the DC voltage sources in series and in
parallel. Then the researched inverter can huge numbers of voltage levels in the
equal number of switching devices by using the conversion system. When we reduce
the number of gate driving circuits, which leads to reduce the size and power
consumption in the driving circuits. And also reduce the THD (Total Harmonic
Distortion) of the output waveforms. Unlike traditional multilevel inverters,
this topology does not require an external voltage balancing circuit, a
complicated control scheme, or isolated dc sources to maintain its voltage
levels while delivering sustained real power. The simulation results are carried
by MATLAB/SIMULINK SOFTWARE.

Vijaya Lakshmi Nallagopula, S.Yasoda Krishna
Abstract-Power sector faces great troubles in the generation of power when the
energy sources are renewable resources. These resources may not be available at
a constant rate continuously. In wind power generation the velocity of wind is
not constant all the time. So the input will not be stable. In such condition a
front end boost converter is added to step-up the DC voltage when the energy
resources are at weak point. By using the single stage boost inverter with
coupled inductor may leads improved reliability, high boost gain and efficiency.
Simulation and experimental results are presented to verify good performance.

Analysis Of Flexible Hose Used To Drive A Fire Fighting Water Monitor Trailer
Prof.Prashant.Kadu , Nilesh.Raut, Dr. K. S. Zakiuddin
Abstract-When a place catches fire it is well observed fact that a most of the
time is wasted by the fireman while extinguishing fire due to larger distance
present between the place of the fire and the hose or water monitor. Because of
which huge amount of water is wasted because of evaporation during jet impact.
It is impossible to take water monitor close to fire because of high
temperature. Hence, an effective fire fighting cannot be done. As it requires
delivery of water at right time, right place and in adequate quantity. To reduce
the distance present in between water and place of the fire an innovative method
of fire fighting using hydraulically driven vehicle is developed by Prof.
Prashant S. Kadu. The vehicle uses the pressurized water from the pump to move
forward taking into account the property of straitening, elongation and buckling
of special purpose hose used for fire fighting. When the water is pumped, then
pushing force developed due to straightening property of the fire hose is used
to move the vehicle [1]. As flexible hose is used as medium to drive the trailer
there is intense need to analyse the behaviour of hose and stress induced in it.
The increasing trend of stress is observed with reduction in diameter of hose
and increase in pressure of water. In this paper, efforts were taken to analysis
the behaviour of hose at different pressure, when hose is straight and bends.
This research will help to determine stress induced inside hose when it is
straight or bend and the response of hose when hose is use as drive.

Abstract-In the paper I evaluate and compare the three routing algorithms using
the NS-2 Simulator. I selected the DSDV routing as the representative of the
table driven protocols because it maintains a loop free hop, which means the
creation of fewer forwarded packets, path to every destination in network. DSDV
achieves a low routing overhead and low average delay. I selected AODV as the
second algorithm for the comparisons because it support unicast and mulicast
packet transmissions and it achieves the lowest routing overhead from the other
protocols in its category.

remote associations in a metropolitan scale. In this paper, we
contemplate the issue of distinguishing the greatest accessible
transfer speed way, a basic issue in supporting nature ofadministration
in Wmns. Because of impedance among
connections, transmission capacity, a well-known bottleneck
metric in wired systems, is not curved or added substance in
remote systems. We propose another way weight which catches the
accessible way data transfer capacity data. We formally
demonstrate that our jump by-bounce steering convention focused
around the new way weight fulfills the consistency and circle
freeness necessities. The consistency property ensures that every
hub settles on a legitimate bundle sending choice, so that an
information parcel does navigate over the expected way. Our
broad recreation explores likewise demonstrate that our proposed
