Another example of this may be given. Focusing a very high energy laser beam on a piece of metal can actually melt the metal. Equipment using high energy lasers are used in industry to accurately cut and weld sheets of metal. As for surveying‚ everyone

CHAPTER 2 LITERATURE REVIEW 2.1 Introduction Before conducting analysis of crash analysis of a Proton Gen-2 between bumper and rigid wedge‚ information and related journals are reviewed. In this chapter‚ firstly the stress strain diagram is used to start the literature review since it is the basic behavior of a specimen under applied force. Next‚ factors of selecting bumper system components such as the energy absorbing and recyclability are discussed to introduce the properties of a good bumper

Department of Mechanical Engineering‚ Jawaharlal Nehru Technological University‚ Kukkatpally‚ Hyderabad-85 b ABSTRACT ARTICLE INFO In pulsed Nd:YAG laser welding process‚ the material melts and solidifies consecutively by a peak high power laser beam. The solidification time in this process is very less as compared to that of conventional welding process. The mode of welding process is governed by the process parameters like laser energy‚ pulse duration‚ pulse frequency‚ power and welding speed

optic links‚ except the beam is transmitted through free space. While the transmitter and receiver must require line-of-sight conditions‚ they have the benefit of eliminating the need for broadcast rights and buried cables. Laser communications systems can be easily deployed since they are inexpensive‚ small‚ low power and do not require any radio interference studies. The carrier used for the transmission signal is typically generated by a laser diode. Two parallel beams are needed‚ one for transmission

History of Gymnastics The word gymnastics derives from the common Greek adjective γυμνός (gymnos) meaning "naked"‚ by way of the related verb γυμνάζω (gymnazo)‚ whose meaning is "to train naked"‚ "train in gymnastic exercise"‚ generally "to train‚ to exercise". The verb had this meaning‚ because athletes exercised and competed without clothing. Exercises of the ancient Greeks began with athletic feats performed by each individual according to his own notion. The youth were encouraged to combine

PERFORMANCE OF CARDBOARD CARTON FORMS Abstract: Cardboard carton forms (void boxes) are commonly used to form the void space between the bottom of grade beams and slabs over expansive soils. However‚ other than laboratory compression tests and 100% humidity tests‚ there is little documentation for the actual performance of these boxes in place. This paper summarizes field tests done in an attempt to simulate actual conditions to answer the following questions: • Do the boxes deteriorate at
