Power Factor Correction of Linear and Non-linear Loads Employing a Single Phase Active Power Filter Based on a Full-Bridge Current Source Inverter Controlled Through the Sensor of the AC Mains Current
Abstract:
In the last years the number of non-linear loads has been increasing rapidly. This non-linear load had drawn a current form the AC Mains with harmonic components, leading to low power factor, low efficiency, interference by the EMI, among others. A classic solution is the use of passive filters, which ....etc

A STUDY ON WEAR AND EROSION PROPERTIES OF RAIL STEEL



Introduction:
Steels represent the most important group of engineering materials as they have the widest diversity of applications of any of the engineering materials. Generally, carbon is the most important element profoundly affecting the mechanical properties of the steels. The term steel is used for many different alloys of iron. These alloys vary both in the way they are made and in the proportions o ....etc

Abstract:
pin-on-disk tribometer is an advanced Tribometer with precise and repeatable measuring of the friction and wear properties of combinations of metals and lubricants under selected conditions of load, speed and temperature. the elements of the tribometer are a pin sliding on the flat face of a disk rotating in a vertical plane, with provisions for controlling load, speed and oil temperature, and for measuring friction. The test oil is contained in a cup in which the disk rotates ,The pure sliding used in this test causes b ....etc

THEORETICAL ANALYSIS FOR STUDYING THE
FRETTING WEAR PROBLEM OF STEAM GENERATOR
TUBES IN A NUCLEAR POWER PLANT
ABSTRACT



Fretting, which is a special type of wear, is defined as small amplitude relative motion along the contacting interface between two materials. The structural integrity of steam generators in nuclear power plants is very much dependent upon the fretting wear characteristics of Inconel 690 U-tubes. In this stu ....etc

ABSTRACT
Miniaturization is the order of the day. Until recently a decade ago traditionally watch parts were considered to be the micro components one can think off. Recent changes in societyâ„¢s demand have forced us to manufacture variety of micro components used in different fields starting from entertainment electronics to be bio medical implants. Present day manufacturing processes used for miniaturization are the micro electronic fabrication techniques used for Micro Electro Mechanical Systems ....etc

Abstract:
Tribometer is an instrument that offer precise and repeatable wear/friction measurement of a surface. Friction testing can be carried out in various environments to simulate the real life scenarios. Tribometer testing rigs can take numerous geometries but generally take the form of a loaded probe that impinges the sample that travels in a circular or reciprocating fashion. In this seminar we present different methodology used in advanced Tribometer and the working principle of Pin on disc Tribometer

INTRODUCTION
Since the worldâ„¢s resources of material and energy are getting progressively, by necessity, there is growing involvement in studies of wear on a global basis. Wear of sliding components result in reduced mechanical efficiency and an irretrievable loss of material in the form of wear debris. Wear at the interface between moving particles is a normal characteristic of machine operation. The kind and rate of wear depend on the machine type. Lubrication is provided between the moving su ....etc
