My interest in oscillators started many years ago when I was an undergraduate student and one of the laboratory experiments was the design of a Colpitts oscillator. It was amazing to see how a sinusoidal signal appeared when the power supply was turned on. What an interesting way of controlling the motion of electrons in the circuit!...

After being shrouded in esoterica for a long time, Global Navigation Satellite Systems (GNSS) have become part of everyday life, especially the Global Positioning System (GPS). Having spent 40 years involved with the subject, it became clear to me that it would be useful to have a book about the business aspects of these systems. This...

This book provides an overview of steganography and digital watermarking, two areas of research which are generally referred to as "information hiding." Steganography studies ways to make communication invisible by hiding secrets in innocuous messages, whereas watermarking originated from the need for copyright protection of...

In late 2001, Bill Gates was having dinner with a group of journalists on the night before Microsoft’s launch of the Windows XP operating system. At that time, the dotcom crash was just unfolding, and during dinner, Bill Gates said (correctly) that the dotcom bubble was a distraction and caused a lot of money to be wasted on...

Progress in biology is dependent on the ability to observe, measure, and model the behavior of organisms at multiple levels of abstraction, from the microscopic to the macroscopic. There has been a tremendous growth recently in the techniques to probe the structure and workings of cellular and organ-level mechanisms. Significant advances have...

VoIP is poised to take over from the century-old public switched telephone network (PSTN). But VoIP telephony does not enjoy the same privacy as the old PSTN. This is because PSTN phone calls were based on establishing a “closed circuit” between the two parties, while VoIP phone calls send packets through the Internet, which...

An ontology is a set of vocabulary terms with explicitly stated meanings and relations with other terms. Presently, a growing number of ontologies are being built and used for annotating data in biomedical research. Thanks to the tremendous amount of data being generated, ontologies are now being used in numerous ways, including connecting...

This newly revised, authoritative resource is essential reading for professionals looking for a clear, complete overview of basic electromagnetics principles and applications to antenna and microwave circuit design for communications. Among the numerous updates, the second edition features a brand new chapter on the increasingly important topic...

Unlike other books on wireless sensors networks, this unique reference focuses on methods of application, validation and testing based on real deployments of sensor networks in the clinical and home environments. Key topics include healthcare and wireless sensors, sensor network applications, designs of experiments using sensors, data...
