Prologue,rd in our quality of life. Due to the discovery of the laser in 1960 optical energy in large quantities and in a controlled form is now available as a new form of energy for the civilised world. So it is reasonable to have great expectations.

Background and General Applications,scillate back and forth between the mirrors for ever, if not prevented by some mechanism such as absorption. Between the mirrors is an active medium which is capable of amplifying the light oscillations by the mechanism of Stimulated Emission (the process after which the laser is named - Light Ampli

Laser Surface Treatment, for opaque materials, such as metals, and there are no associated hot gas jets, eddy currents or even radiation spillage outside the optically defined beam area. In fact the applied energy can be placed precisely on the surface only where it is needed. Thus it is a true surface heater and a unique

Epilogue,of life, as has been the case with the mastery of other forms of energy. Thus the expectation was high. Hopefully the patient reader has seen in the chapters of this book that some of this expectation is beginning to shape up. It seems appropriate, therefore, to finish with a little thoughtful wande

William M. Steend checkpoints. So, in our previous work, an algorithm was introduced to allow each process to autonomously remove useless log information in its volatile storage by piggybacking only some additional information without requiring any extra message and forced checkpoint. However, even after a process

William M. Steenw-resolution (LR) images are one of the common issues encountered in ALPR systems. Most of the available algorithms in ALPR systems are effective under controlled circumstances or with intricate image capture systems. Authorities are looking for an improved ALPR system that is primarily concerned wi
