Twenty five years have elapsed since the original publication of Helium Cryogenics. During this time, a considerable amount of research and development involving helium fluids has been carried out culminating in several large-scale projects. Furthermore, the field has matured through these efforts so that there is now a broad...

Generally a laser (light amplification by stimulated emission of radiation) is defined as “a device which uses a quantum mechanical effect, stimulated emission, to generate a coherent beam of light from a lasing medium of controlled purity, size, and shape”. Laser material processing represents a great number of methods, which are...

From cell phones to treating cancer, EM energy plays a part in many of the innovations that we take for granted everyday. A basic force of nature, like nuclear energy or gravity, this energy can be harnessed and used, but still holds the potential to be harmful. The question remains, how safe are EM products? Bioeffects and Therapeutic...

This comprehensive survey provides a thorough account of the recent deployment of infrared sensors in modern applications of...

Phenomena occurring during a contact of two bodies are encountered in everyday life. In reality almost every type of motion is related to frictional contact between a moving body and a ground. Moreover, modeling of simple and more complex processes as nailing, cutting, vacuum pressing, movement of machines and their elements, rolling or,...

This book encompasses the different technologies employed in thermal ablation, its indications and the results achieved in various clinical conditions. It clearly explains the basics of thermal ablative techniques. In the main part of the book, techniques of guiding the applicators to the target structures by use of different imaging tools...

Signal processing may broadly be considered to involve the recovery of information from physical observations. The received signal is usually disturbed by thermal, electrical, atmospheric or intentional interferences. Due to the random nature of the signal, statistical techniques play an important role in analyzing the signal. Statistics is...
