Interception Probability and
Shielding Against Lightning
A comprehensive analysis on shielding against lightning is presented in this article. The design of its protection zone and collection volume is an important topic for an air terminal. The lightning interception
probability is a term which refers to the close conformity between the actual and calculated number of lightning strikes. The data shows that there is a relationship between the calculated and actual number lightning strikes. for an accurate description of lightning i ....etc

Why nuclear energy came into account:
Conventional thermal power stations use oil or coal as the source as the source of energy. The reserves of these fuels are becoming depleted in many countries and thus there is a tendency to seek alternative sources of energy. In a nuclear power station instead of a furnace there is a nuclear reactor, in which heat is generated by splitting atoms of radioactive mat ....etc

Introduction:
Welding Processes:
Welding is the most economical and efficient way to join metals permanently. Welding is used to join all of the commercial metals and to join metals of different types and strengths.
A weld is produced either by heating the materials to the welding temperature with or without the application of pressure alone with or without the use of filler metal. There are different kinds of welding processes who all use different sources of heat, for instance arc welding which uses an electric ....etc

Abstract
The application of a superconductor to a faultcurrent limiter in a power system has been researched.We developed a magnetic shielding type superconductingfault current limiter using a Bi2212 thick film cylinder.This limiter consists of a primary winding on asuperconducting cylinder for generating an AC magneticfield, the cylinder for shielding the field, an iron core formagnetic members and a control ring for controlling faultcurrents. When a fault occurs, the superconductivecylinder quenches and a magnetic circuit is formed ....etc

Introduction:
The plasma welding process was introduced to the welding industry in 1964 as a method of bringing better control to the arc welding process in lower current ranges. Today, plasma retains the original advantages it brought to industry by providing an advanced level of control and accuracy to produce high quality welds in miniature or precision applications and to provide long electrode life for high production requirements.
The plasma process is equally suited to manual and automati ....etc

WELDING
Welding is a fabricationprocess that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the work ....etc

ABSTRACT

Electromagnetic bombs are Weapons of Electrical Mass Destruction with applications across a broad spectrum of targets, spanning both the strategic and tactical. As such their use offers a very high payoff in attacking the fundamental information processing and communication facilities of a target system. The massed application of these weapons will produce substantial paralysis in any target system, thus providing a decisive advantage in the conduct of Electronic Combat, Offensive Counter Air and Strategic Air Att ....etc

ABSTRACT

Biomagnetism is a science in which magnetic fields produced by organs or by magnetic contaminants of the body are studied. The science of Biomagnetism applies a technology that was originally developed for the measurement of extremely small magnetic field in physics. Health is determined by the electromagnetic vitality of the cells to maintain the perfect chemical balance. Properly designed bio-magnetic field can dynamically manipulate the electrical charge of the cellular tissue back to a normal healthy con ....etc

ABSTRACT
Welding being the major asset and salvation for mechanical
engineering, the seminar is all about the automation of major welding
processes used in industries using robots, which was hitherto done
manually under hazardous and perilous working environs. The seminar
dwells with two major industrial welding processes namely continuous
arc welding process and spot welding process. It also connects with
essential features of the robots used in these welding processes and
also the adv ....etc

Celldar is made from two words: cell and radar. This is a passive multistatic radar system, which is based on radiation of mobile base stations and can track moving objects. The concept of cell phone radar could provide a totally covert and innovative approach to the detection of land, air and sea-based objects. The hardware required is much simpler than existing radar systems, though the signal-processing software is complex. Previously, radar needed massive fixed equipment to work and transmissions from mobile phone ma ....etc

Pulsed Spray Metal Transfer


What is Pulsed Spray Metal Transfer?

Pulsed spray metal transfer
(GMAW-P) takes advantage
of the high energy of Axial Spray
Metal Transfer, and alternates
this high energy (peak) current
with a lower energy (background)
current. Each cycle is called
a period, and the period can
repeat several hundred times
per second.


The Adaptive Loop

Many pulsed spray metal transfer software programs
are designed with an ....etc

INTRODUCTION

The next Pearl Harbor will not announce itself with a searing flash of nuclear light or with the plaintive wails of those dying of Ebola or its genetically engineered twin. You will hear a sharp crack in the distance. By the time you mistakenly identify this sound as an innocent clap of thunder, the civilized world will have become unhinged. Fluorescent lights and television sets will glow eerily bright, despite being turned off. The aroma of ozone mixed with smoldering plastic will seep from outlet covers as electric wires arc ....etc
