Residual Stress Management
Residual stresses, as detailed above, may be disastrous, in combination with other factors to structures involving welded metals. The minimization of this residual stress is critical fror prolonging the life of such structures. Cold working techniques, such as shot peening, laser shock peening, ultrasonic peening, planishing, hammering, burnishing, low plasticity burnishing, rolling,...
...INTRODUCTION Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld. (www.wikipedia.org). A weld is defined as a blend or coalescence of two or more metals by heating then until they reach a critical temperature and flow together. The piece of metal to be welded is called the base metal, work piece, or work. The edges of the base metal are often specially prepared for...

Operating principles of common turbomachines
Turbomachines or turbines are defined as the hydraulic machines which convert hydraulic machines into mechanical energy. This mechanical energy is used in running an electric generator which is directly coupled to the shaft of the turbine.
If the water flows parallel to the axis of the rotation of the shaft, the turbine is known as axial flow turbine. If the head at the inlet of the turbine is the sum of pressure energy and kinetic energy and during the flow of water through runner a part of pressure energy is converted into kinetic energy, the turbine is known as reaction...
...CHAPTER 4 QUALITATIVE CONTENT ANALYSIS Purpose of the Paper As the use of machine increases, so do the scope of their utility and the strength of their capabilities. With computers and robots trying to achieve human-level intelligence, human kind have often paused to consider whether machines have actually gained the capability to think. ‘Can machines think?’ is a question posed by the famous British mathematician and computer scientist Alan Hume Turing who proposed the Turing Test to gauge the thinking capability of machines or computers. This paper examines the questions from different perspective and endeavors to come to a definite conclusion on whether...

Hydraulic machines are those machines which convert hydraulic energy into mechanical energy (further converted into electrical energy) or mechanical energy into hydraulic energy. The former types of machines are called turbines and the latter, pumps.
Impact of a Jet onto a vane
A combination of both pump and turbine is used in fluid couplings and torque converters for the transmission of power smoothly through a fluid medium. The analysis of impact of fluid jets on vanes is typically involved in the design of an efficient turbo-machine.

Urbanization is the general process of leaving the ancient way of life and adopting the modern life characterized by advanced technologies. By 1900, cities developed due to the economic as well as technological evolutions. More industries were built in centers having large populations where workers to labor in the manufacturing firms where housed. The centers had railway lines to ensure easy mobility of raw materials and finished products. More people also settled along the shores and river fronts due to easy transport.
By 1887, electric car by Frank Sprague was the major transport mode in the cities; this replaced the ancient horse transport. Skyscrapers were constructed using steel rods...

...Welding Thin Materials Affiliation Welding Thin Materials Shielded metal arc welding (SMAW) is a process that uses an expendable electrode plastered in flux to melt and fuse metals. An arc between the metals being joined and the electrode is formed by means of an electric current. The electric current can either be an alternating current or direct current. As the weld is performed, the flux layer covering the electrode degenerates, producing a layer of slag and a shielding gas, both of which guard the weld from contamination until it cools. Tungsten inert gas (TIG) welding is a welding method in which, a non- expendable...
