Channel Characterisation and System Design for Sub-Surface Communications By David Gibson
eBook (PDF): $54.62
Download immediately.
Based on the author's PhD thesis, this book is a theoretical study of subterranean radio communication, with the focus on methods that depend primarily on the penetration of electromagnetic fields... More > through the ground. Through-the-earth communication using e-m fields - specifically magnetic induction - plays a role in search and rescue systems used in the mining industry. It is also used for borehole telemetry, pipeline location and by cavers and pot-holers. Chapters describe propagation, antennas, and the design of transmitters and receivers. A figure of merit - the specific aperture - is introduced as an aid to antenna design. A crucial aspect of all systems is the signal to noise ratio, for which the strategy of noise-matching is introduced. The design of a wide-band low-frequency sounder is described, for channel evaluation using a non-ideal binary sequence. A method of calculating the inverse of a generalised sequence is described, for which cross-correlation results in a system identification signal.< Less

BioInformation Processing: A Primer On Cognitive Modeling Volume One By James Peterson
Hardcover: $59.95

This book is a primer on how information is processed in a typical mammalian brain. To talk about these ideas intelligently, the reader needs to use ideas from mathematics, computer science and many... More > areas of science. Intertwining these normally separate areas into a coherent whole provides an introduction to modern interdisciplinary work. In the book, we develop carefully how an excitable neuron collects information from many sources and then outputs a single voltage pulse which carries a variety of signaling information. Our modeling efforts are based on the use of MatLab (although octave is just fine) so it should be easy to do experiments yourself. We cover the usual basics of axonal pulse propagation including Hodgkin-Huxley models, dendritic cable models, first and second messenger signalling system abstractions and so forth. This book provides a good foundation towards building models of cognition which may be used for models of depression and other forms of dysfunction.< Less
