Halftone secure with Error Diffusion techniques for Visual
Cryptography
Shital B Patel, Vinod L. Desai
Abstract — A Security becomes a major concern for data
transmission using image techniques and also used for the hiding
of information in images. Visual Cryptography is a cryptography
technique which allows to hide visual information (image,
printed text etc.) within image. In Visual Cryptography the
image is divided into two part called shares and then they are
distributed to the participants. At Decryption side just stacking
the share images and gets the original images. In this paper, we
produce an enhanced form of the proposed method by modifying
the encryption technique by halftone error diffusion scheme.
When the share are generated, it is uses the halftone processing,
which first the encryption images with high quality secret image
and the decryption the secret images with same image quality by
using error diffusion methodology with higher quality images.
We studies various image quality measurement parameters
based on different techniques and which contains fast execution
,accuracy and minimum error value and with a better value of
PSNR, MSE, WSNR ,SNR and UQI.

Improving Life Time for Output Shaft (Gear Box) in
Dryer Unit-by Mathematically
R.Vivek, M.Sugumar
Abstract — This paper reports the results of failure
analysis of dryer gear box output shaft, the shaft
operates continuously for a year but the failure occurs
periodically for the paper industry. Which fail
permanently after every three months of continuous
working, this is one of the major problems in industry.
The major causes of failure of the shaft are to the
impulse force and radial force. Beach marks on the
fracture were clearly visible. Fatigue cracks were
initiated at the corners of the bearing. Relatively small
final fracture surface indicated that the shaft was under
a low stress at the time of failure. The premature failure
occurred due to high stress concentration at the corner
of the shaft bearing, which led eventually to fatigue
crack initiation, crack growth and final fracture.
Improved design and manufacturing practice suggested
that this would prolong service life of the shaft.

measurements
Sreenivas B.C, G.C.Bhanu Prakash
Abstract — Congestion control is a key problem in mobile ad -
hoc networks. Congestion has a severe impact on the
throughput, routing and performance. Identifying the
occurrence of congestion in a Mobile Ad-hoc Network
(MANET) is a challenging task. The congestion control
techniques provided by Transmission Control Protocol
(TCP) is specially designed for wired networks. There are
several approaches designed over TCP for detecting and
overcoming the congestion. This paper considers design of
Link-Layer congestion control for ad hoc wireless networks,
where the bandwidth and delay is measured at each node
along the path. Based on the cumulated values, the receiver
calculates the new window size and transmits this
information to the sender as feedback. The sender behavior
is altered appropriately. The proposed technique is also
compatible with standard TCP.

Evolution of Medical Education among Women in Tamil
Nadu during the Colonial Period (India)
Premalatha P.N.
Abstract — The late 19th and early 20th centuries were considered
to be very important in the medical history and medical
education in India. The government started opening civil
dispensaries and introduced western medicine. It is to be
remembered that in India even before the spread of general
education among women, attempts were made to start medical
education for women. It was sought as early as in the later part
of the nineteenth century with the intention to afford relief to the
ailing women who could not consult men doctors. The system of
seclusion had not only been a hindrance to women's freedom but
it made them suffer a great deal when they were ill, for there
were no women Doctors to attend them. It had been estimated
that in British India maternal deaths approximately were about
two lakh. In fact it was this suffering that persuaded women
doctors to take medical career and their service became
invaluable. It is noteworthy to mention that a few progressive
women were willing to study with men to receive medical
training in Madras. In the year 1875, Madras Medical College
admitted four women students. By 1944, there were 209 women
and 651 men studying in Madras Medical College and Stanley
Medical College. This paper highlights the progress of medical
education among women and the efforts taken by the British
Government, the native kings and women medical missionaries
to promote medical education.

Clustering-based spectrum sensing
In cognitive radio wireless sensor networks
Vybhav N, Uma S
Abstract — A cognitive radio wireless sensor network (CR -WSN)
where each sensor node is equipped with cognitive radio. A
typical concern in CR-WSN is energy consumption due to
resource-constrained nature of sensor nodes. Moreover,
additional energy is consumed in a CR-WSN to support CRexclusive
functionality such as spectrum sensing and switching,
which could shorten sensor node lifetime. However, some sensor
nodes could receive similar signal due to similar channel
condition such that they probably have same spectrum sensing
results. A clustering based scheme for spectrum sensing in CRWSN,
which reduces energy consumption by involving less nodes
in spectrum sensing. With improved clustering algorithm, sensor
nodes are grouped into different sets based on their similarity in
sensing result. In order to identify the optimal cluster number, a
new objective function, based on new intra-cluster and intercluster
proximity measures is proposed which can effectively
reduce the energy consumption of sensor node and improve
global detection probability. Cluster analysis or Clustering is
said to be a collection of objects. It is used in various application
in the real world. Such as data/text mining, voice mining, image
processing, web mining and so on. It is important in real world in
certain fields.

Implementation of Direct Torque Control Scheme for
Three Phase Induction Motor Drives
K.Rajesh, G.Arun kumar, D.Sathish
Abstract — Induction motor drives (IMD) are currently used in
many industrial applications due to its reliability, ruggedness
and easier in maintenance. To reach the best efficiency of IMD,
many new techniques of control have been developed in the last
few years. These drives controlled with the vector control (VC)
method have found wide applications in the industry. However,
this control technique requires complex coordinate
transformation, inner current control loop and accurate system
parameters. An efficient method of induction motor control is
the direct torque control (DTC). DTC method provides robust
and fast torque response without such coordinate
transformations, PWM pulse generation and current
regulators. Moreover, DTC minimizes the use of motor
parameters. This paper presents a study of DTC technique for
voltage source inverter fed induction motor drives using
MATLAB. Simulation results have shown the validity and high
accuracy of the proposed model.

Neelam Rajput, Vishal chaudhary
Abstract — Large number of algorithms have been
evolved on account of natural phenomenon's and
swarm behavior. Natural phenomenon's and swarms
behavior are the warm area of research among the
researchers. These algorithms have been executed on
the different computational problems for the sake of
solutions and gave critical outcomes than conventional
system yet there is no such algorithm which can be
connected for the greater part of the computational
problems. This paper proposes an optimisation
algorithm called Grasshopper Optimisation Algorithm
(GOA) and applies it to challenging problems in
structural optimisation. The proposed algorithm
mathematically models and mimics the behaviour of
grasshopper swarms in nature for solving optimisation
problems. The GOA algorithm is first benchmarked on
a set of test problems to test and verify its performance
qualitatively and quantitatively. The results show that
the pro- posed algorithm is able to provide superior
results compared to well-known and recent algorithms
in the literature. The results of the real applications also
prove the merits of GOA in solving real problems with
unknown search spaces.

Analysis of a High Rise Building with Viscous Dampers
using ETABS
G.Karthik, P.Lakshmaiah Chowdary
Abstract — The basic principles of design for vertical and lateral
loads (wind & seismic) are the same for low, medium or high rise
building. But a building gets high both vertical & lateral loads
become controlling factors. The vertical loads increase in direct
proportion to the floor area and number of floors. In contrast to
this, the effect of lateral loads on a building is not linear and
increase rapidly with increase in height. Due to these lateral
loads, moments on steel components will be very high. By
providing viscous dampers these moments can be reduced.
In the present analysis, a residential building with 20 floors is
analyzed with columns, columns with viscous dampers at
different locations were for all the 2 cases. The building is
analyzed in Zone 3 & Zone 5 with three soils in both static &
Dynamic Analysis. Moments, Shear, Displacement were
compared for all the cases. It is observed that the deflection was
reduced by providing the Viscous dampers.

Protect the AODV Protocol with Secure Routing
Information Protocol from Gray Hole Attack
Niharika Sood, Rasbir Singh
Abstract — Today MANETs has reached to its pinnacle,
as the demand for the MANETs are increasing day by
day. Due to the increasing demand for MANETs in
various areas such as in Military operations, in flood
affected areas etc., threat of security has also increased.
MANETs has no protection from harms, so information
can be accessed by both authorized network users and
catty attackers as MANETs don’t have centralized
administration. In the presence of catty nodes, the main
problem in MANETs is to design the rich security
solution that can protect MANETs from various routing
attacks. Flooding attack is kind of the security threat in
which source node sends huge amount of data, Root
Request (RREQ) and Sync packet to destination node,
due to which the receiver shall not work properly as it
would be engaged in receiving the excessive amount of
data, RREQ and Sync packets from the attacker. In this
paper we apply Gray hole attack on MANET & check
the performance of the network after then we apply
routing information protocol on the network to increase
the performance of the network.

Beginning of the Bust in an Ecommerce sector?

Abstract — Never before have entrepreneurs and
entrepreneurship in India been as feted and funded as
we are seeing today. In Roman mythology, unicorns are
creatures with the body of the horse, head of the deer
and a single horn sticking out from the middle of the
foreheads. Start ups that are valued at over a billion
dollars are dubbed as unicorns because they were
supposed to be a myth, both investors and
entrepreneurs could dream of, a rare phenomenon. Not
anymore, though US today boasts of over 50 unicorns,
India has at least a dozen, Shopclues being the latest one
to achieve the distinction in January,2016. With the
amount of funding flowing into the start ups, there is
invariably some fear that we are approaching another
bubble , and the euphoria surrounding the start ups
currently was last seen in the heydays of the first
dotcom boom, just before the crash. To a certain extent,
this is correct, as highly funded start ups that have
spent enormous money on branding will inevitably run
out of cash one day and will close down. However,
though a lot of start-ups will fail, as is the nature of
game, there will be some revolutionary ones who would
emerge as winners and would have changed the rules of
game forever.
