This paper is an overview of the sources and nature of various transient over voltages and the problems that may result in a low voltage ac distribution system. Voltage transients may be repeatable transients or random impulses and they have got remarkable effects on semiconductors, electrochemical contacts, insulation etc. Switching parallel loads on the same branch of distribution system as well as lighting are responsible for these transient overvoltages. Low voltage ac mains system should be protected from these transient overvoltages. For ....etc

1.INTRODUCTION

A pump is a machine that draws a fluid into itself through an entrance port and forces the fluid out through a machine that draws a fluid into itself through an entrance port and forces the fluid out through an exhaust port. A pump may serve to move liquid, as in a cross-country pipeline; to lift liquid, as from a well or to the top of a tall building; or to put fluid under pressure, as in a hydraulic brake. These applications depend predominantly upon the discharge characteristic of the pump. ....etc

This article describes about a new approach for securing localization and location verification in wireless networks based on hidden and mobile base stations.The goal of this article is to enable localization with a broad spectrum of localization techniques,
ultrasonic or radio, based on the received signal strength or signal time of flight.Localization and ranging techniques in wireless networks mainly rely on measurements of the time of flight of radio (RF ToF) or time of flight of ultrasound signals (US ToF) and on the measurements of recei ....etc
