Effect of Squeeze pressure on the hardness and wear resistance of Aluminium flyash composite manufactured by stir-squeeze casting
K.N.P. Prasad1, M. Ramachandra

Abstract: In the present investigation LM6 aluminium alloy was reinforced with 7.5% by weight flyash particles. The composite was prepared by stir-squeeze casting method. Different squeeze pressure was applied on the composite to study the effect of squeeze pressure on the hardness and abrasive wear behavior of the composite. It was observed that as the squeeze pressure was increased the hardness and the wear resistance also improved. The wear experiments were conducted.............

Some Aspects on 3-Phase Bridge Inverter (180 Degree Mode)
Ananya Dutta

Abstract:
This paper presents the Simulink model for 3 phase inverter in 180 degree mode. The three-phase square wave inverter can be used to generate balanced three-phase ac voltages of desired (fundamental) frequency. Moreover, harmonic voltages of 5th, 7th and other non-triplet odd multiples of fundamental frequency distort the output voltage......

A novel approach for Zeolite-based Materials for Gas Sensors
Mr.K.Jegan Mohan, Dr.K.Jagadeesan, Dr.Aravind Yadav

Abstract:
This paper deals with the uses of zeolites and zeolite-based materials for developing gas sensors. The purpose of using zeolites in sensors is usually to improve sensitivity and selectivity by preferential adsorption, in addition, thin films assure a fast response time of the sensor. The compound or cluster sensing towards a gas assembled into the cages or channels of zeolites property of the materials were disussed in this paper. The possibility of these materials is tinted and avenues for further research are suggested.

Systematic Design of Hybrid Cascaded Multilevel Inverters with Simplified DC Power Supply and low Switching Losses
S.Hariprasadhsingh, 2P.Raju, S.Zabiullah

Abstract:
Hybrid cascade multilevel inverters combine semi conductor devices of different voltage ratings and technologies which theoretically allow high efficiency to be achieved. The bottlenecks of these topologies are, however, the need for isolated supplies for the cells and the lack of modularity. This paper focuses on the design and control of high-resolution, high-efficiency multi level inverters with simplified dc power supplies. for which all unsupplied capacitor voltages can be regulated Six classes..............

Optimizing of Bloom Filters by Automatic Bloom Filter Updating and Instantly Updating Service Availability on Peers in P2P Network
Amulia P.M, Jisha G

Abstract:
P2P networks have become popular in the distributed computing paradigm. Different search mechanisms are used in P2P networks. Although flooding search technique, often provide required search results, this technique incurs lot of unnecessary traffic in the network. Bloom filter technique was developed to reduce the network traffic and thereby reduce communication cost. The main drawback of bloom filter is false positive results. False positives increase when data becomes stale. To reduce the stale data problem the paper proposes a mechanism to automatically updating the bloom filter information............

Method to control the output power of Laser in the variation of Ambient Temperature
Ghanshyam Kumar Singh

Abstract:
This paper presents a method to control the output power of Laser in the variation of ambient temperature. The circuit was designed using a feedback loop to maintain a constant optical power in the presence of temperature variation. It has been shown that the small variation in the photo-detector current, in response to a small variation of the laser output power, the PI controller adjusts the bias voltage so that the current through the laser remains constant. As a result, the output optical power is kept constant. The OptiSpice software has been used which incorporates equations governing optical components directly into an electrical stimulation.
Keywords: Laser, Photo-detector, PI Controller & OptiSpice.
