8 Influence of Stress in Spur Gear at Root Fillet with Optimized Stress Relieving Feature of Different Shapes
Haider Ali, Gomish Sharma
Abstract - Failure of gear causes breakdown of system which runs with help of gear. When gear is subjected to load, high stresses developed at the root of the teeth. Due to these high stresses, possibility of fatigue failure at the root of teeth of spur gear increases. There is higher chance of fatigue failure at these locations. So to avoid fatigue failure of the gear, the stresses should be minimized at maximum stress concentrated area. This work presents the possibilities of using the stress redistribution techniques by introducing the stress relieving features in the stressed zone to the advantage of reduction of root fillet stress in spur gear. This also ensures interchangeability of existing gear systems. In this work, combination of circular and elliptical stress relieving features are used and better results are obtained than using circular stress relieving features alone which are used by earlier researchers. A finite element model with a segment of three teeth is considered for analysis and stress relieving features of various sizes are introduced on gear teeth at various locations. Analysis revealed that, combination of elliptical and circular stress relieving features at specific, locations are beneficial than single circular, single elliptical, two circular or two elliptical stress reliving features.

10 An Integrated High Gain Boost Resonant Converter for PV System
M. Sridhar, S.Sathishkumar, R.Nagarajan, R.Yuvaraj
Abstract - The Effective photovoltaic power conditioning requires well-organized power conversion and accurate maximum power point tracking to neutralize the effects of panel mismatch, shading, and variation in power output during a daily cycle. This paper presents a unique method for widening the input range of pulse width modulation of integrated resonant converters and it maintains high conversion efficiency. The technique primarily unites constant-on, constant off, and fixed-frequency control depending on the required duty cycle. With hybrid-frequency control, the circuit also retains zero current switching for the output diodes, minimizes the switching loss, and eliminates circulating energy at the transformer across the entire operating range. The Z-source inverter (ZSI) is widely used in low-voltage input applications such as photovoltaic, fuel cells, motor drivers due to its outstanding compared with the traditional voltage source inverter (VSI). Worst of all, the boost ability is too small. Several control strategies are provided to overcome these disadvantages of the classic ZSI, but they still have limits to avoid the discontinuous input current, as well as reduce the voltage stress. More importantly, the stronger boost ability is achieved, the larger shoot-through duty ratio should be used, which will result in a poor output voltage profile and low voltage-conversion ratio. Thus, the control strategies are not efficient to improve the boost ability.

Trishita Ghosh, Rajat Singh, Namrata Sharma, Avijit Nath
Abstract - The prime goal of Vehicular Ad hoc Network (VANET) is to provide life safety on the road. To achieve this, vehicles make use of two types of safety messages one is Periodic safety messages (beacons) to exchange status information e.g. position, speed etc. and second one is Event-driven messages to broadcast in case of an emergency situations e.g. accidents, hard-braking etc. The main objective of congestion control in VANET is to best exploit the available network resources while preventing sustained overloads of network nodes and links. Appropriate congestion control mechanisms are essential to provide efficient operation of a network. Ensuring congestion control within vehicular ad hoc networks faces special challenges, due to the specificities of such environment (high mobility of nodes, high rate of topology changes, high variability in nodes density and neighborhood configuration, broadcast communication nature, etc.). In this context, we present a congestion control approach, to ensure efficient bandwidth usage of control and service channel within VANET. It supports dynamically adjusting the load of beacon messages.

26 Preserving Location Based Range Query over Outsourced Data with EPLQ Using LOCX
M. Karthika, Dr. K. Geetha, Dr. D.Yuvaraj
Abstract - Location-based services (LBS) require users to continuously report their location to a potentially untrusted server to obtain services based on their location, which can expose them to privacy risks. However, the use of LBS also poses a potential threat to user's location privacy. In this paper, LocX, a novel alternative is introduced which provides significantly-improved location privacy without adding uncertainty into query results or relying on strong assumptions about server security. Our key insight is to apply secure user-specific, distance-preserving coordinate transformations to all location data shared with the server. This allows all location queries to be evaluated correctly by the server, but our privacy mechanisms guarantee that servers are unable to see or infer the actual location data from the transformed data or from the data access.
