A Review on variable steering ratio
-Suraj S. Serigar ; Dhiraj Tiwari; Sujeet Oza; Omkar Bhoite; Dhiraj Raut
At present most of the automobiles have fixed steering ratio for steering mechanisms. Steering ratio refers to the ratio between the turn of the steering wheel and the turn of the wheels. But the interpretation of this system does not change with changing road and dynamic condition of automobile. Thus, there is a need to differ the steering ratio of automobile depending upon the conditions in which it is being driven. For example we require moderate steering ratio at high speed and low steering ratio during parking and driving in busy streets to maintain dynamic stability of the vehicle. Using microprocessor controlled steering the driver can swiftly change the steering ratio of its vehicle to adjust to the condition. The following study enlightens the use of microprocessor to vary the steering ratio at the will of the operator. Read More...

Experimental analysis of two loops system for high heat flux microelectronics cooling
-Ms. P.D.Giradkar ; Dr.U.S.Wankhede
As electronics advance and require higher power densities, the demand for efficient cooling methods increases. Due to high heat flux capability, two-phase cooling systems may be applied to cool a wide variety of newly emergent technologies such as power electronics seen in electric-drive vehicles. In this work, the experimental results of the cooling performance of a pump-assisted and capillary-driven two-phase loop, which utilizes a unique planar evaporator are discussed. Water was used as the working fluid. The evaporator was fed liquid by both mechanical and capillary pumping, while the vapor and liquid phases in the evaporator are separated by capillary force to prevent it from flooding. The experimental results of the two phase loop system with a single evaporator handling a single heat source shows the proper boiling condition under a stepwise heat load with sudden power variation. The effects of various operation variables of the two-phase cooling loop, such as dynamic and stepwise heat input, liquid flow rate, high heat flux, on the cooling performance of the two-phase loop are discussed.

-Wagh Supriya Vilas ; Upadhyay Nilesh Biharilal; Gandhi Neel Mukesh; Katkade Shital Ramkrishna
as the vast research in the eld of technology increases, location dependent applications becomes highly important as positioning and tracking of mobile devices plays an important role in context aware and pervasive services. While physical localization and logical localization for satellite has been highly and extensively researched, networks with xed reference points like GSM and WiFi are densely deployed and tracking and positioning techniques in Sparse Disruption Tolerant Networks (DTN) have not been well researched. In this paper, we propose a cooperative and localized method called Pulse Counting for DTN localization and a probability based tracking method called ProbTracking to solve the problem. To evaluate user walking steps and movement orientation, we use Pulse Counting by using cellphones accelerometer and electronic compass. By exploiting the encounters of mobile nodes, it improves the accuracy and estimates user’s location by accumulating walking segments. There are several methods for renement of location estimation which are also discussed, such as, mutual renement of location estimation for encountering nodes based on maximum likelihood and adjustment of trajectory based on reference points. We use ProbTracking method to track user movement which uses Markov chain to describe movement patterns and predicts the most possible user walking trajectory without full record of users location.

Comparison of Reinforced Concrete and Pre-stressed Concrete Flat Slabs in Tall Buildings
-Ruchi R Kadamb ; M.Manjunath
Flat slab are usually preferred floor system for tall buildings as they result in reduction in floor heights. The flat slabs without drop panel and column head are called as flat plates. The design of tall buildings is usually governed by the lateral loads imposed on the structure. The main disadvantage of flat slabs and flat plates is their lack of resistance to lateral loads, such as those due to wind forces and earthquakes. In the present study tall building with reinforced concrete flat slab floor system is compared with pre-stressed concrete flat slab floor system under lateral forces. A 30 storied tall building with a flat plate floor of size of 30m x 24m and having a panel size 6m x 6m is studied for wind forces. These slabs are design as reinforced concrete as well as pre-stressed (post tensioning) concrete flat slabs as per Indian standard codes and analysed in software SAP2000. The analysis and design results of reinforced concrete and pre-stressed concrete flat plates are compared to evaluate the performance of the tall building in resisting the lateral wind forces.

-Sagar Chandrakant Saibewar ; Prof. Bharati Dixit
Face recognition is the task of identifying an already detected face as known or unknown face and has attracted much attention due to its potential value in security, biometrics and law enforcement applications. One of the most difficult challenges in automated face recognition is computing facial similarities between face images which are acquired in alternate modalities. To address this problem Heterogeneous Face recognition comes takes place. Heterogeneous face recognition (HFR) involves matching two face images from alternate imaging modalities, such as sketch to a photograph or an infrared image to a photograph. The Proposed work is based on experimentation using Heterogeneous Face Recognition framework using Prototype Random Subspace Approach for both probe and gallery images which are represented in terms of nonlinear similarities to a collection of prototype face images. The proposed work will be evaluated on various performance parameters with accuracy as the main focus and pre-processing time required for filtering the images using DOG, GF, and CSDN filters. This framework performs equally well for different modalities whereas the focus of the study is specifically for Face Photo-Sketch Recognition Accuracy and Recognition time required using DOG, GF, and CSDN filters. The accuracy of this nonlinear prototype representation is improved by projecting the features with the help of PCA The outcome of this work will be useful in the areas like forensic sciences, video surveillance etc. The paper also shows a comparative study of Heterogeneous Face Recognition framework for both probe and gallery images which are represented in terms of nonlinear similarities to a collection of prototype face images and an approach to Heterogeneous face recognition which needs feature descriptors that are effective within each domain.

Development of Rainfall Intensity-Duration-frequency Relationships from Daily Rainfall Data for the major cities in Bangladesh Based on Scaling Properties
-Md. Majadur Rahman
The rainfall Intensity-Duration-Frequency (IDF) relationship is one of the most commonly used tools for various engineering projects against floods. It is important in water resources engineering, either for planning, designing and operating of water resource projects. For estimation of runoff especially for urban areas short duration rainfalls are necessary. Developing countries like Bangladesh short duration rainfall is scarce and data available is mostly for daily rainfall data. In such cases, design rainfall is estimated by approximation and thus leading to frequent failure of drainage network. The purpose of this paper is to develop an empirical formula to estimate design rainfall intensity for seven major cities based on simple scaling properties. This method allows for the estimation of the design value of rainfall of selected return period and durations shorter than a day by using only the daily data. The assumption of simple scaling implies in direct relationships between the moments of different orders and the rainfall durations, which can be used to derive IDF relation¬ships from larger durations.

An Experimental Investigation of Piston Coating on Internal Combustion Engine
-Prof. Parvez F. Agwan ; Prof. Swapnil.A.Pande
The thermal efficiency of most commercially used engine ranges from 38% to 42%, as nearly 58% to 62% of energy is lost in the form of waste heat. In order to save energy the hot parts are insulated. This will lead to reduction in heat transfer through the engine, involving an increased efficiency. Change in combustion process due to insulation also affects emissions. In this study an attempt is made to reduce the intensity of thermal and structural stresses by using a layer of ceramic material. Experimental investigation is carried out under different loading conditions on single cylinder two stroke spark ignition engine with its piston crown coated with Nickel-Chromium & Al2O3 to understand the influence of thermal barrier coating (TBC) on performance characteristics. Al2O3 is chosen as a candidate material for coating the piston crown because of its desirable physical properties like low thermal conductivity, high coefficient of thermal expansion, high thermal resistance, chemical inertness, high resistance to erosion, corrosion and high strength. Thermal barrier coating (TBC) is done by using Plasma Spraying Technique. Engine working conditions are maintained constant before and after coating. Experimental results revealed that the thermal efficiency is increased by 13.75%, Mass of fuel consumption is reduced by 6.02% and brake specific fuel consumption is reduced by 9.84% between coated and bare engine.

Classification Of Faults In Series Compensated Transmission Line Using Wavelet
-Prof. Mrs. Swapna ; Prof. Arun M. Patokar
Fault detection is very tedious task in transmission lines with a fixed series capacitor because of the nonlinear behavior of protection devices and seriesparallel resonance. This paper proposes a new method based on DWT for fault classification in this series capacitor is fixed at the middle of the line. The DWT is used here for extracting the unseen factors from the fault current signal and here harr is used as a mother wavelet. The average values of the wavelet coefficients of the lower frequency band for the currents of three phases and ground are computed and as there are higher frequency components in the faulted phases than that of the unfaulted phases, the fault classification can be done easily. The performance of the proposed scheme is checked for the all possible faults at various locations, different compensation levels and different power angles. This transient fault study is carried out using the PSCAD software and the wavelet transform and protection algorithm is implemented in a MATLAB environment. Read More...

Dynamic Analysis of Overhung Rotor System with Bearing Defect
-Bhoomi Shaileshbhai Naik ; Prof. U. A. Patel
In this paper an analytical model is proposed to study behavior of overhung rotor-defective bearing system. Overhung rotor is considered with unbalanced mass and bearing is taken as cylindrical roller bearing having surface defect. To analyze all system component’s effect at one node, finite element method is used to predict exact system vibrations. Euler-Bernoulli’s beam element is used to discretize shaft. Gyroscopic effect of overhung rotor is also taken into account. Governing equation of motion has been modified according to our system. Hertz contact stress theory is used for every roller-race contact to calculate overall nonlinear bearing force. Governing differential equation is solved by newmark-beta time integration method. Nonlinear matrix equation which is generated at each time-step in newmark’s method is solved by Broyden’s quasi-newton method. Results at defective bearing is obtained and plotted in time and frequency domain. Higher level Poincare maps are drawn to view system’s minimum stability time. Whole analysis work is done in software package MATLAB. The current study provides a powerful tool for design and health monitoring of overhung rotor systems. Read More...

Development of Dual Axis Solar TRACKER System
-Prajapati Vivekkumar Nareshkumar
The energy extracted from solar photovoltaic (PV) or solar thermal depends on solar insolation. For the extraction of maximum energy from the sun, the plane of the solar collector should always be normal to the incident radiation. The diurnal and seasonal movement of the earth affects the radiation intensity received on the solar collector. Sun trackers move the solar collector to follow the sun trajectories and keep the orientation of the solar collector at an optimal tilt angle. Energy efficiency of solar PV or solar thermal can be substantially improved using solar tracking system. In this work divided into two stages, which are software and hardware development. In software development, we have to simulate dual axis solar tracker by using four LDR sensor in hardware development, an automatic solar tracking system has been designed and developed using LDR sensors and DC motors on a mechanical structure with gear arrangement. Two-axis solar tracking (azimuth angle as well as altitude angle) has been implemented through active solar tracker based comparator logic. Performance of the proposed system over the important parameters like solar radiation received on the collector, maximum electrical power per day, efficiency has been evaluated and compared with those for single axis tilt angle solar collector.

Design and Development of Rack-inMechanism of Air Circuit Breaker
-Keval Devrajbhai Goti ; Bharat Modi; Rajender Niranjan
Demand of electrical energy without interruption has increased nowadays. To meet the requirement, the reliability of each individual component should also be high. Air circuit breaker (ACB) is an automatically operated electrical switch, which is mainly used for low voltage power distribution. For easy maintenance and inspection, draw-out types ACB is used. Rack-in mechanism is used to connect and disconnect the breaker within a cradle by applying torque manually using rack-in handle. Typical rack-in mechanisms often require a high force to rack-in and rack-out of the circuit breaker, and the amount of force re-quired increases as the number of electrical contacts to be engaged increases. As the num-ber of contacts is increased, the force applied to actuate a typical rack-in mechanism may exceed ergonomic limitations. Lesser torque is desirable in manual rack-in operation to reduce human fatigue. Three rack-in mechanisms have been thought and direct translation type rack-in mechanism has been found optimum as per grid analysis comparing other rack-in mechanism. A prototype of selected rack-in mechanism was fabricated as per the CAD model to validate the results. Read More...

A Review on Detecting an Attackers In VoIP Using Honeypot
-Kurhade Supriya B. ; Palwe chaitali B.; Pande Priyanka R.
The number of users of VoIP services is increasing every year. Basically, VoIP systems are more attractive for attackers. This paper describes the implementation of a low interaction honeypot for monitoring illegal activities in VoIP environments. The honeypot operated during 92 days and collected 3502 events related to the SIP protocol. The analysis of the results allows understanding the modus operandi of the attacks targeted to VoIP infrastructures. These results may be used to improve defence mechanisms like firewalls and intrusion detection systems. SIP is one of the major VoIP protocols and has its architecture composed of four basic elements: user agent, SIP proxy, redirect server and registry server. The user agent (UA) is a logical function that matches the architecture of the client. It is responsible for initiating or replying to SIP transactions and can act as both client (UAC) and as a server (UAS), starting SIP requests and SIP responses accepting, or accepting SIP requests and answering them, respectively. There are few implementations on VoIP security and attacks in real-world VoIP systems. Some of them propose the use of honeypots to catch malicious traffic in a VoIP environment. Honeypots can be defined as a computational resource to be probed, attacked and / or compromised, whose value lies precisely in the unauthorized or illegal use of the resources offered. Read More...

The Status of Living Place and the Health Condition of Women in the Slum of Chennai City, Tamil Nadu
-S.John Kaviarasu ; Dr. G. Gladston Xavier
This research has explored the health status of women from the slums of Chennai city Tamil Nadu State. In fact, most of the slums in the city of Chennai in general do not have proper sanitation facilities. Therefore, they attend the call of nature by going behind the bushes situated alongside railway tracks. Women prefer to go for open defecation under cover of darkness, either late in the evening or early morning. Environmental scenario in slums is usually unsafe and therefore, it is a matter of concern as it poses serious threats to the health and wellbeing of slum dwellers in general and pregnant women and lactating mothers in particular. The study brings out the reasons for the rising health problems faced by women in slums due to general environmental condition, lack of potable water supply, sanitation system and poor nutrition (Panda 1993). The study analyses various other reasons associated with poor living condition of the women and its impact on the health of the slum population. Interview Schedule was used to elicit the primary data from 80 women from 4 informal settlements in Pudupet area of Egmore. This study adopted descriptive research design to understand the general health conditions of women and also explain their health status and health seeking behaviour. The unhygienic environment of the slums and lack of basic amenities affect the health and wellbeing of the slum dwellers in general and women and children in particular. Normally, women do not take healthy diet as they have to take care of their family members, particularly their children. Lack of healthy diet and nutritional foods greatly affect their health. It is due to poverty, women take rice mostly obtained from the ration shops. This study clearly reveals that women’s poor health status is mainly because of early marriage, early pregnancy and improper pregnancy spacing. Moreover, the study discloses that more than 36% of women have more than three children. A whopping 87% of the women delivered their first child before the age of 21. As women are less educated, their level of awareness on health and wellbeing is also very low. Therefore, findings of the study suggest that the problem of the poor living conditions of women have to be addressed by the health departments, government agencies, Chennai corporations and slum clearance board.

-MANI BHUSHAN ; Er. SURENDRA KUMAR SRIWAS
This paper present a MATLAB/Simulink model of a four junction tandem solar cell GaInP/GaAs/GaInAs/Ge for high efficiency. Tandem solar cell means it has more than one junction. The energy band gaps of the sub-cells in a GaInP/ GaAs/ InGaAs/ Ge 4-J tandem solar cell are 1.9 eV, 1.4 eV, 1.1eV and 0.75 eV respectively. In a space applications, generally triple junction from III-V compound semiconductor GaInP/GaAs/Ge is used, because it delivered highest efficiency compare to other commercially available triple junction solar cell. In a multi-junction solar cell, increasing the number of junctions generally offer higher efficiencies. We study here the mathematical model and electrical equivalent circuit of four layer multi-junction solar cell and compare with the triple junction and single junction solar cell and simulation of 4-layer multi-junction solar cell is discussed. We analyzed these models in various environmental conditions such as: solar irradiation, cell’s working temperature and concentration of suns. In this we consider three main factors: maximum power (Pmax), open circuit voltage, Short circuit current density of the solar cell. Taking into account the overall effect of solar irradiance and temperature, the model are evaluated, resulted simulated data are presented. It also include the effect on the bandgap of each sub-cells as well as diode reverse saturation current due to variation in the temperature. Read More...

Multi-Cloud Hosting For Performance Optimization and Security
-Gade Pooja Vilas ; Mate Shweta Anant; Janjalkar Priti Sudhir
Many organizations and enterprises stores data into the cloud to reduce maintenance cost and also to increase reliability of data. While hosting their data into cloud, customer faces many cloud vendors as well as their pricing policies so that the customer may get confused with which cloud(s) are suitable for storing data. CHARM propose a data hosting scheme which combine two key functions- first function is selecting a cloud to store data in minimum cost and guaranteed availability and second is triggering transition process to re-distribute data. It can do according to pricing of clouds and variations of data patterns. While sending data to Third-Party administrative control in cloud, it also becomes an issue related to security. We need high security measures to protect data in a cloud so we use DROPs concept that solves security and performance issue. In this we divide data into fragments and replicate that fragments into cloud nodes and each node contain only a single data. All these nodes are separated with a certain distance using graph T-colouring. Using this security and performance optimization is done. Read More...
