A moving train contains energy, known as kinetic energy, which needs to be removed from the train in order to cause it to stop. The simplest way of doing this is to convert the energy into heat.

The conversion is usually done by applying a contact material to the rotating wheels or to discs attached to the axles. The material creates friction and converts the kinetic energy into heat. The wheels slow down and eventually the train stops. The material used for braking is normally in the form of a block or pad

Introduction

High-temperature protective coatings used in gas turbine components must withstand extremely severe environmental conditions. There are two basic coating systems, which are currently being used in gas turbines to provide improved corrosion and oxidation resistance, and thereby extend the component life. These are called diffusion coatings and overlay coatings. The diffusion coatings provide a surface enrichment of aluminum, chromium, or silicon, and aluminizing behavior of nickel-based superallo ....etc

Vacuum electronics technology is both old and new. It will continue to be enabling technology for entire classes of high power high frequency amplifiers with the most demanding specification for use in military and commercial systems. The report will give brief introduction on various vacuum electronic amplifiers such as helix TWT, gyro amplifiers, multiple beam-amplifiers, power modules along the basics and the advance in the past few decades with different performance curves.

The advantages and the future of these are mentioned in last pa ....etc

Abstract
the history and diversity of this remarkable technology, with emphasis on advances in vacuum-electronic amplifiers, including the microwave power module (MPM), that have been enabled by the ongoing development of modeling and simulation tools. These physics-based codes, enabled by rapid advances in computational hardware, allow simulation-based design and optimization of complex vacuum-electronic circuits. The growth of satellite-based digital communications technology over the past decade has opened lucrative commercial opportunitie ....etc
