Chepuri, S.P. (author)
In today's society, we are flooded with massive volumes of data in the order of a billion gigabytes on a daily basis from pervasive sensors. It is becoming increasingly challenging to locally store and transport the acquired data to a central location for signal/data processing (i.e., for inference). To alleviate these problems, it is evident...

Golshani, N. (author)
Radiation detectors are used in a large variety of fields such as medicine, security, defense, geophysics, industry and physics. They have been developed to detect the energy or position of radiation or charge particles. In Chapter 1 several X-ray detectors were introduced briefly. In gas filled X-ray detectors, incoming photons ionize inert gas...
