Information Security using Cryptography and Image Processing
-R. B. Joshi ; Avanti Deshpande
Meaning of Information security is protecting information and the systems from unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction. Therefore it is necessary to apply effective encryption/decryption methods to achieve data security. The user only needs to remember the short password to retrieve the key. The password can be forgotten and stolen. As Biometrics based authentication systems confirm an individual's identity based on the physiological and/or behavioral characteristics of the individual. It has advantages over password based methods. Biometrics based method provides direct link between the service and actual user. With biometrics, there is nothing to lose or forget, and it is relatively difficult to manipulate. Biometrics and cryptography are the two most prominent solutions for user authentication, data integrity preservation, and trustworthy verification. By combining biometrics with cryptography, high level of security can be achieved. Read More...

A Compatibility Study on Different Types of Cement and Plasticizer
-Dr. Jayesh A. Shah ; Mr. Dipak S. Gaud; Mr. Dhiren K. Paghdar; Mr. Rushabh A. Shah; Mr. Vyom B. Pathak
It has long been a concrete technologist's dream to discover method of making concrete at the lowest possible water/cement ratio while maintaining a high workability. To a considerable extent this dream has been fulfilled with the advent of super plasticizers. It has added a new dimension to the application of admixtures with regards to production of high strength and flow able concretes. It is now possible to produce concrete with compressive strength of the order of 90Mpa (90 N/mm2). In the wake of energy conservation policy and diminishing supplies of high quality raw materials, there is a need to use marginal quality cements and aggregates for the production of concrete. In such instances the use of plasticizers/super plasticizers permits the production of concrete at low water/ cement ratios. We have taken ultra tech opc cement & coromandal ppc cement to find the compatibility by adding perma plast (plasticizer). The water cement ratio was maintained as 0.40 &0.45 for OPC & PPC respectively. To study the effect of these PP on various properties of concrete. The dosage of plasticizers/super plasticizers was measured as 1.5% for Perma plast for OPC & 1.3% for PPC by the weight of cement. Read More...

Safety Optimization in Bikes
-Syed Abdul Khader Hussainy ; Neer Mariappan. M
Introduction of fast moving bikes in our country has disturbed the condition of Indian roads. Rash driving is the major concern with these bikes which has led to accidents all over. Today's generation which normally prefer super bikes (150cc or more) accounts for most of the accidents taking place in the country. Comparing previous census, the number of accidents taking place have increased drastically. Though bikes have high safety systems like disc brake, ABS, etc which can arrest the motion of wheel and stop the vehicle at any speeds, the problem here arises with pillion rider. When braking is applied at high speeds, the rear wheel is lifted up and bike comes to stoppie position and throws off the pillion rider from the vehicle. Pillion riders hardly wear helmet, thus it leads to serious injuries even leading to death. To minimize these kind of accidents, a special kind of shock absorber has been designed which absorbs shocks to greater extent. This shock absorber uses slider mechanism supported by springs placed beneath the rear seat. The rear seat is fitted with rollers which slide inside the rail, thus providing a slider motion. This slider motion is supported by springs of calculated stiffness which returns the roller to initial position after the action. When there is sudden breaking, deceleration is produced which brings the slider mechanism in action. The roller moves forward which leads to movement of seat forward and also the pillion rider. This pushes pillion rider forward rather than being thrown off from the vehicle. The spring plays a vital as it brings back the seat to initial position after the action is performed. Spring has another advantage as it reduces the shock produced during the movement of seat back and forth due to sudden breaking. Implementation of this method is easy as it requires slight customization in the rear seat. The rear seat is separated from driver's seat and slider mechanism is made beneath the rear seat. Setting up of this shock absorber is cheap and affordable. Read More...

A Review on Potential of Utilizing Metal Industry Wastes in Construction Industry
-Dr. Neeraj D. Sharma ; Mr. Hiren A.Rathod; Mr. Dipak S. Gaud
This exploration work is an effort to develop the awareness & importance of industrial waste management & its utilization in productive manner in construction industry. In today's more environmentally-conscious world, a more responsible approach to the environment is to increase the use of by-products of one industry which is disposed off as a waste but can be used as a raw material for some other industry. Traditionally materials like clay, sand, stone, gravels, cement, brick, block, tiles, etc. are being used as major building materials in construction sector. All these materials have been produced from the existing natural resources and will have intrinsic distinctiveness for damaging the environment due to their continuous exploitation and increasing cost incrementally. Hence it is essential to find functional substitutes for conventional building materials in the construction industry. For above purpose the exploration study is carried out for understanding and determining the scope of utilization of waste from metal industry such as silica fume, copper slag, foundry waste sand and ground granulated blast furnace slag (metal industry) in construction industry. In our country annually huge quantities of wastes are produced by the industries. Instead of disposing-off these wastes if they are utilized in such a manner then it will provide an eco-friendly solution, simultaneously solving the problem of pollution and raising the step towards economy & obviously towards progress of the nation.

Survey of Hybrid Encryption Algorithm for Mobile Communication
-Nishit Mishra ; Ishita Bhatia
To enhance the security of data transmission in Mobile communication, a hybrid encryption algorithm based on DES and RSA is proposed. The currently used encryption algorithm employed to protect the confidentiality of data during transport between two or more devices is a 128-bit symmetric block cipher. In the proposed hybrid encryption algorithm, DES algorithm is used for data transmission because of its higher efficiency in block encryption, encryption speed of DES algorithm is faster than RSA algorithm for long plaintext, and RSA algorithm distribute key safely and easily also RSA algorithm is used for the encryption of the key of the DES because of its management advantages in key cipher. Under the dual protection with the DES algorithm and the RSA algorithm, the data transmission in mobile communication system will be more secure. Meanwhile, it is clear that the procedure of the entire encryption is still simple and efficient. Digital abstract algorithm MD5 is adopted in this mechanism. Through comparing the digital signature which is transmitted by dispatcher and digital signature result of plaintext which is got by receiver through MD5 algorithm, data security can be guaranteed. This mechanism realizes the confidentiality, completeness, authentication and non- repudiation. Read More...

Energy Efficient LEACH protocol for Wireless Sensor Network (I-LEACH)
-Deepak Dembla ; Shivam H. Mehta
in the wireless sensor networks (WSNs), the sensor nodes (called motes) are usually scattered in a sensor field an area in which the sensor nodes are deployed. These motes are small in size and have limited processing power, memory and battery life. In WSNs, conservation of energy, which is directly related to network life time, is considered relatively more important souse of energy efficient routing algorithms is one of the ways to reduce the energy conservation. In general, routing algorithms in WSNs can be divided into flat, hierarchical and location based routing. There are two reasons behind the hierarchical routing Low Energy Adaptive Clustering Hierarchy (LEACH) protocol be in explored. One, the sensor networks are dense and a lot of redundancy is involved in communication. Second, in order to increase the scalability of the sensor network keeping in mind the security aspects of communication. Cluster based routing holds great promise for many to one and one to many communication paradigms that are pre valentines or networks. Read More...

Simulation of Doubly Fed Induction Generator
-Pragnesh Patel ; Pankaj Valand
in recent years, wind energy has become one of the most important and promising sources of renewable energy, which demands additional transmission capacity and better means of maintaining system reliability. The wind energy conversion systems are connected to the grid through Voltage Source Converters (VSC) to make variable speed operation possible. The studied system here is a variable speed wind generation system based on DFIG using MATLAB Simulation. DFIG is the hybrid version of the Induction Generator. In the DFIG no extra auxiliary equipment is required to compensate the reactive power because the design of DFIG is such a way that reactive power is compensate by the Rotor Side or Grid Side Converter. The rotor side converter (RSC) usually provides active and reactive power control of the machine while the grid-side converter (GSC) keeps the voltage of the DC-link constant. Results show that the DFIG can work at variable speed; it gives the optimum output at respective speed. But induction generator only works at fixed speed. The power output is more reliable in DFIG. In induction generator capacitor bank or STATECOM is used for compensate the reactive power. In DFIG there is no need of such equipment's for compensating the reactive power. DFIG is more stable at Transient Fault Condition than IG. Read More...

Fatigue or Durability Analysis of Steering Knuckle
-Patel Akash A.
the purpose of the study of this thesis is to discuss analysis the acting force upon the steering knuckle while in track or random load for a vehicle. Steering knuckle is main important part in the vehicle because that requires lots of attention in selection because once it is damaged then it have to replace with the new one.
Structural Components such as a steering knuckle might be strong enough to withstand a single applied load. But what happens when the part operates over and over, day after today? To predict component failure in such cases requires what's called fatigue or durability analysis.
For our purposes, a constant or static load does not cause failure. What counts is the impact of working or fluctuating loads. Failures, or fractures, take place when cracks get so large that remaining material can no longer endure stresses and strains. In classic structural analyses, failure predictions are based solely on material strength or yield strength. Durability analysis goes beyond this, evaluating failure based on repeated simple or complex loading. Read More...

Equal Switching Distribution Method for Multi-Level Cascaded Inverter
-Rituparna Guchhayat
the paper proposes a new method of equal
switching distribution that can be applied to cascaded multilevel
inverters. This method is based on the fact that in the
cascaded multilevel inverters, the output phase voltage is the
sum of voltage waveforms produced by all cascaded cells.
By periodically exchanging cells' voltage waveforms, the
proposed method ensures equal average switching's
distribution between all cascaded cells. This method is
applied to the 13-level inverter, which consists of three
cascaded 5-level H-bridge cells per phase. However, the
proposed method can be extended to any desired number of
voltage levels and applied to any type of cascaded multilevel
inverter. Extensive simulation results of the tested 13-
level inverter with the equal switching distribution are
presented. Moreover, the proposed method is compared to
the standard control approaches and its advantages are
shown. Read More...

Slider Crank Mechanism for Four bar linkage
-Patel Ronak A.
the slider crank mechanism is a particular four
bar linkage configuration that exhibits both linear and
rotational motion simultaneously. This mechanism is
frequently utilized in undergraduate engineering courses to
investigate machine kinematics and resulting dynamic
forces. The position, velocity, acceleration and shaking
forces generated by a slider crank mechanism during
operation can be determined analytically. Certain factors are
often neglected from analytical calculations, causing results
to differ from experimental data. The study of these slight
variances produces useful insight. The following report
details the successful design, fabrication and testing of a
pneumatically powered slider crank mechanism for the
purpose of classroom demonstration and experimentation.
Transducers mounted to the mechanism record kinematic
and dynamic force data during operation, which can then be
compared to analytical values. The mechanism is capable of
operating in balanced and unbalanced configurations so that
the magnitude of shaking forces can be compared. The
engine was successfully manufactured and operates as
intended. Data recorded by the device's accelerometers is
comparable to calculated values of acceleration and shaking
force. Read More...

Stress Analysis and Design Modification of 3-stage Helical Gear Box Casing
-Patel Mitesh S.
the finite element analysis of 3 stage helical
gearbox that constitutes the driving mechanism of a double
bascule movable bridge was performed. The triple reduction
helical gearbox was made of ASTM A36 Steel. The triple
reduction helical gearbox was a three stage gearbox
transmitting 112.5 H.P. at 174 rpm with a reduction ratio of
71.05:1. The Differential gearbox was a single stage
gearbox transmitting 150 H.P. at 870 rpm with reduction
ratio of 5:1
The load calculation for helical, herringbone, and
bevel gears were performed using the MATHCAD Software
package. The reactions were used to apply loads to the finite
element model of housing (casing). Geometric model of 3
stage helical gearbox was built using NX-8 and meshed
using the ANSYS finite element program. Linear structural
analysis was performed using a combination of shell and
solid elements to determine the deflection and to estimate
the stress distribution in the housing. Nonlinear analysis was
later performed using shell, solid, and beam & gap elements
to determine if the interface between the two halves of the
housing separated and contributed to any undesirable
misalignments of the shafts or bearings.
In the triple reduction gearbox, the axial forces
caused a maximum displacement 0.05588 cm. The location
and magnitude of the displacements would not contribute to
the undesirable misalignment of the shafts and bearings. The
maximum von Misses stress in the triple reduction gearbox
was 9000 psi. The minimum factor of safety in the triple
reduction gearbox was four. The nonlinear analysis
determined that separation did not occur on the interface
between the two halves of the gearbox housings. Read More...

The Effects of Mutual Coupling and Transformer Connection Type on Frequency Response of Unbalanced Three Phases Electrical Distribution System
-Janmejay Vyas
in this paper, a novel harmonic modeling
technique by utilizing the concept of multi -terminal
components is presented and applied to frequency scan
analysis in multiphase distribution system. The proposed
modeling technique is based on gathering the same phase
busses and elements as a separate group (phase grouping
technique, PGT) and uses multi-terminal components to
model three-phase distribution system. Using multi-terminal
component and PGT, distribution system elements,
particularly, lines and transformers can effectively be
modeled even in harmonic domain. The proposed modeling
technique is applied to a test system for frequency scan
analysis in order to show the frequency response of the test
system in single and three-phase conditions. Consequently,
the effects of mutual coupling and transformer connection
types on three-phase frequency scan responses are analyzed
for symmetrical and asymmetrical line configurations. Read More...
