Abstract- Now a days there are low-cost computers, storage devices and high-capacity networks are available which led to a growth in cloud computing. Cloud provides the advantage in scalability and cost-saving. The service owners can get the advantage on scale up or down the service and only pay for the hours of using the servers. The workloads of query services are highly dynamic and serving such workloads within house infrastructure will be inexpensive and inefficient. Data confidentiality and query privacy have become major concerns because the service providers lose the control over the data in the cloud. The data owner does not want to move to the cloud unless the data confidentiality and query privacy are guaranteed for the sensitive data..It is also necessary for a secure query service to provide efficient query processing and also reduce the in-house workload, because the purpose of using cloud resources is to reduce the need of maintaining scalable inhouse infrastructure. Data confidentiality, query privacy, efficient query processing, and low in-house processing cost are the requirement for constructing practical query service in the cloud. Satisfying al this requirement will increase the complexity of building query services in cloud. Some related approaches are there which will address some aspects of problem. We give the comparative study of these approaches with their limitations.

Abstract Slum is a heavily populated urban informal settlement characterized by substandard housing and poor civic amenities. While slums differ in size and other characteristics from country to country, most lack in reliable sanitation services, supply of clean water, reliable electricity, timely law enforcement and other basic services. Slum residences vary from shanty houses to densely-built dwellings with poor-quality design, construction and maintenance. Slums form and grow in many different parts of the world for many different reasons like rapid rural-to-urban migration, economic stagnation, high unemployment, poverty, informal economy, poor planning, political disturbance, natural disasters, social conflicts, etc. Strategies tried to reduce and transform slums in different countries, with varying degrees of success, include a combination of slum removal, slum relocation, slum upgrading, urban planning with city wide infrastructure development, and public housing projects. The objective of the present paper is, to analyse the impact of institutional interventions in infrastructure development on slum settlement and their subsequent growth pattern.

Abstract The Z-Source Inverter (ZSI) has been reported suitable for residential PV system because of the capability of voltage boost and inversion in a single stage. Recently, four new topologies, the quasi-Z-Source Inverters (qZSI), have been derived from the original ZSI. This project analyzes one voltage fed topology of these four in detail and applies it to PV power generation systems. By using the new quasi-Z-Source topology, the inverter draws a constant current from the PV array and is capable of handling a wide input voltage range. It also features lower component ratings and reduced source stress compared to the traditional ZSI. A prototype which provides three phase 50-Hz, 230Vrms ac has been built in laboratory. It is demonstrated from the theoretical analysis and MATLAB/SIMULATION results that the proposed qZSI can realize voltage buck or boost and dc-ac inversion in a single stage with high reliability and efficiency, which makes it well suited for PV power systems.

Abstract This paper deals with review of the previous related research on evaluation of soil liquefaction due to Carbon sequestration by various Carbon Capture Sequestration processes in geological pits. It provides critical literature recommendations on evaluation of soil liquefaction potential assessment. The detection of soil liquefaction by using seismic records has been developed by various researchers. With this information, the evaluation of soil liquefaction are well understood and this lead to a more precise and confident output. Gaining support for CCS will require engaging the interest and building the support of a variety of stakeholders, each with different perspectives and goals. Although, CCS builds upon a technology base developed over more than half a century by the oil and gas industry. In the past, the industrially released CO2 had been introduced to ocean which was harming the aquatic animals. In view of this, the sequestration of CO2 into ocean was internationally banned. Hence, now much of the Carbon sequestration process is done by various industries in geological pits. This creates a major threat to the earth quake problems worldwide. With the enhanced frequency of earthquakes all around the world, it is presumed by many environment scientists that the CO2 sequestration pits leads to soil liquefaction and hence it results in more frequent earth quakes. Therefore, this paper summarises, different methods to evaluate liquefaction potential of soil by using studies from seismic waves generated in earth, it is also propose it is also explains different methodology for an eco friendly technology to reduce CO2 from environment.

Abstract The heat transfer and flow friction characteristics of plate fin surfaces are presented in terms of the Colburn factor j and the Fanning friction factor f verses Reynolds number Re, the relationships being different for different surfaces. The laminar flow model predicts j and f values at low Reynolds number; the data is throughout the range of interest. Velocity, and temperature fields have been computed and j and f factors determined over appropriate range of Reynolds number and geometric dimensions. For this work I have designed heat exchanger according to procedure of design of serrated plate fin heat exchanger [11], correlation used for finding various heat transfer parameters having Reynolds number less than 200 [6]. Experimental setup was manufactured using calculated parameters of design. On this setup readings were taken by varying flow rate of hot oil, at constant air for different temperatures of selected materials. After getting readings calculations were done for heat transfer parameters like Reynolds number, Colburn factor and Fanning friction factor.

Abstract This paper presents unified power quality conditioner (UPQC) which is an integration of shunt and series Active Power Filters and aims to compensate for voltage sag, voltage and current unbalance and other power quality problems [1],[5],[6]. The UPQC helps to improve power quality at the point of installation on power distribution system or industrial power system. This paper deals with design of UPQC by considering a controller based on PQ theory. Reference signal generation for shunt active filter is done by using PQ theory while for series dual PQ theory is used [2], [3]. Reference signals are then applied to pulse generators. Pulse generation is carried out by using hysteresis band controller for each filter. The validation of proposed scheme is carried out by using Matlab/Simulink

Abstract Many heat transfer enhanced techniques have simultaneously been developed for the improvement of energy consumption, material saving, size reduction and pumping power reduction. Screw tape inserts in tubes are a typical technique that offers a higher heat transfer increase and, at the same time, only a mild pressure drop penalty. This study investigates the heat transfer characteristics of a horizontal tube-in-tube heat exchanger having internal threaded pipe with Screw tape inserts of different materials i.e. Mild steel screw tape and Aluminum screw tape inserted in the inner tube. Heat transfer, flow friction characteristics in a threaded tube fitted with screw tape, using oil as working fluid are investigated experimentally. Influences of the changing material i.e M.S screw tape and Aluminum screw tape arrangements are also described. The experiments are conducted using the tapes with same twist ratios and pitch over a Reynolds number range less than 2,000 in a heat exchanger.

Abstract High frequency resonant converters are used widely for induction heating. This paper presents a resonant inverter to achieve the desired high frequency with reduced switching losses and simulating the power electronic converter circuit using MATLAB/SIMULINK for induction heating equipment. The circuit designed has the load as induction coil and high frequency electricity is required to heat the work piece placed within the induction coil. The output power of the load coil is varied by changing the frequency of the inverter. The circuit uses the Power MOSFET instead of the IGBT.The series-resonant inverter is implemented to provide Zero Current Switching (ZCS) for all the switches at turn off conditions and Zero Voltage Switching (ZVS) at diode turn on. The main features of the proposed inverter are simple PWM control strategy and high efficiency. The operation mode of the inverter will be evaluated corresponding to the duty cycle of the switch.

ABSTRACT There is huge activity in wind power, pan-India with the installed capacity increasing to 10,000MW. India today has the fifth largest installed capacity of wind power in the world with 11087MW installed capacity and potential for on-shore capabilities of 65000MW. However the plant load factor (PLF) in wind power generation is very low, often in the single digits. The increase in interest in wind energy is due to investment subsidies, tax holidays, and government action towards renewable energy playing a big part in nation’s energy system. There is a need to generate environment friendly power that not only raises energy efficiency and is sustainable too. The time has come for moving to generation based subsidies and understanding the drawbacks associated with wind power in India. The capital cost of wind power is third higher than Conventional thermal power; further electrical problems like voltage flicker and variable frequency affect the implementation of wind farm. However advances in technologies such as offshore construction of wind turbines, advanced control methodologies, and simulation of wind energy affecting overall grid performance are making a case for wind energy.

Abstract Operation of Induction motors as induction generators in grid connected and self excitation mode is well known. In many countries induction generators are used for electrical power generation by wind energy. Low cost, robustness and ease of maintenance are attractive features of induction generators. Even though these generators are used at some places for micro hydro power generation, very small scale generation known as pico hydro generation offers excellent opportunity for them. Slip ring induction motors are used for micro power generation and squirrel cage induction motors are used for pico power generation. These generators have an inherent problem of terminal voltage variation with increase in load. Several different types of controllers are developed and tested. This paper presents a review of literature related to the present status of research work on self excited induction generators (SEIG), their terminal voltage control strategies and their applications.

ABSTRACT The Ductile-to-Brittle Transition Temperature (DBTT) is a phenomenon that is widely observed in metals. Below critical temperature (DBTT), the material suddenly loss ductility and becomes brittle. The controlling mechanism of this transition still remains unclear despite of large efforts made in experimental and theoretical investigation. All ferrous materials (except the austenitic grades) exhibit a transition from ductile to brittle when tested above and below a certain temperature, called as Transition Temperature. The paper deals with the determination of the ‘Ductile to Brittle Transition Temperature of stainless steel. Work carried out in this is purchasing the material followed by test specimen preparation. The specimens then keep in the liquid nitrogen for cooling for soaking time of 15 min. Then the actual charpy impact testing of the specimens at variable temperature ranging are carried out in controlled atmosphere. The readings taken are the impact energy (joules) of specimen at specific temperature. The graph of energy absorbed vs temperature is plotted to get the range of transition temperature. This paper is a part of 3 papers analyzing the DBTT of • Stainless steel of 304grade • Regular mild steel square rods • Aluminum

Abstract Finite element analysis (FEA) simulations are extensively used in tube manipulation processes such as tube drawing, sinking and extrusion.FEA is one of the most important methods to simulate metal forming. This work aims to find the best geometry of die and plug to reduce the drawing force, and also find the residual stresses in the tube using FEA. Die has been designed with different semi-die angle and plug configurations which are all analyzed through FEA. Geometric, contact to contact surface and material nonlinearity are involved in this problem. The material of pipe used is steel, die and plug material used is tungsten carbide. In tube drawing, the optimum semi-die angles are identified using FEA. In this work, the cold drawing of tubes with fixed plug was simulated by using the commercial software Altair Hyper mesh for pre-processing and Simuilia Abacus for solving and post processing of this study. The project intends to determine the drawing force and stress, and also helps in reducing lead time and try outs and providing products free of defects and with controlled mechanical properties

ABSTRACT This paper presents a case study in the development and application of a time study in a engine block manufacturing plant. The organization engages in the production of two product lines: engine blocks, heads of diverse categories. The motivation for this study was the need to tackle the problem of productivity per shift between the employee-association and the management of the company regarding questions of productivity. The two products have similar production processes. The study’s most important finding is that the time of producing a unit of product is directly proportional to the number of production stages involved and the time spent at each stage. The study focuses on the MAHINDRA production line. Where stud hole and push rod operation is very important for mounting the cylinder head on cylinder block and how to combine this both operation on one single machine like Mahindra job. So the proposal is made to do these two operations for HINO on BMV 60 by adjustment of special fixture like Mahindra. With this proposed solution a saving of 2 to 3 man power per cycle was obtained. The paper discusses the use of Industrial Engineering tools used for the purpose of productivity improvement.
