Determination of Optimum Process Parameters during turning of AISI 304



Introduction and literature survey

In machining process, Surface finish is one of the most significant technical requirements of the customer. A reasonably good surface finish is desired to improve the tribological properties, fatigue strength, corrosion resistance and aesthetic appeal of the product. Nowadays, manufacturing industries specially concerned to dimensional accuracy and surface finish. In order to obtain optimal cutting pa ....etc

This seminar presents the manufacturing processes of thermoplastic structures including piezoceramic patches (PZT). The objective of the study reported here was to find a trade-off between the manufacturing conditions and the thermal endurance of the PZT patches. We studied the influence of high temperatures on the PZT efficiency during manufacturing. Two processes were considered: injection molding and thermoforming. The studied object consists of a polypropylene plate containing a PZT patch integrated at different positions. On the one hand, ....etc

RISK ANALYSIS OF ISLANDING OF PHOTOVOLTAIC POWER SYSTEMS PROTECTION


INTRODUCTION

Under stable steady state operation, all synchronous machines in the grid operate at synchronous speed. Frequency is the measure of load/generation balance. Prevailing frequency of synchronous generators and the Grid depends on matching between (Total MW Load on the Grid plus Losses) and the (Total MW Generation) at that time. Excess Load causes frequency drop. Excess Generation causes frequency r ....etc

ABSTRACT
Today everyone is aiming at a reduction in greenhouse gas emissions, the requirements for adding new generation capacity can no longer be met by traditional power generation methods of burning the primary fossil fuels such as coal, oil, natural gas, etc. This is why distributed generators (DG) have significant opportunity in the evolving power system network. Both consumers and power utilities can benefit from the widespread deployment of DG systems which offer secure and diversified energy options, increase ....etc

operation and control of single phase micro sources in a utility connected grid

Abstract

This paper proposes operation and control of converter based single phase distributed generators (DG) in a utility connected grid. A common utility practice is to distribute the household single-phase loads evenly between the three phases. The voltage unbalance between the phases remains within a reasonable limit. However the voltage unbalance can be severe if single-phase rooftop mounted PVs are distributed randomly between the households. Moreover, ther ....etc

Introduction:
In this 21st century we required a multi functional system to operate on different platforms, which can access data easily, the main purpose of a Heterogeneous server is to establish a Heterogeneous network that can connect computers and other devices with different operating systems and/or protocols. For example, local area networks (LANs) that connect Microsoft Windows and Linux based personal computers with Apple Macintosh computers are heterogeneous. The word heterogeneous network is also used in wir ....etc

On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....etc

Recent surveys have shown the WW is still remaining undiscovered by Search Engines and through Human Intervention. This is primarily due to the lack of Infrastructure and cost factor of such hardware which required to carrying out such processes. My endeavour in finding a solution to this will be focusing on Idle Computer time available in Compute clusters. Deployed client applications will harvest the web and return the results to the Server Computer. Compute Clusters may create through Voluntary Computing or by using specific Infrastructure i ....etc

Abstract

This paper presents an overview of power system islanding and islanding detection techniques. Islanding detection techniques, for a distribution system with distributed generation (DG), can broadly be divided into remote and local techniques. A remote islanding detection technique is associated with islanding detection on the utility side, whereas a local technique is associated with islanding detection on the DG side. Local techniques can further be divided into passive techniques, active techniques and hybrid techniques. These islan ....etc
