The Switching Function

Tue, 12 Jun 2018 01:02:29 GMT

This book demonstrates the usefulness of the switching function in analyzing powers electronic circuits in the steady state. A procedure is suggested for the effective application of this effective application of this method for the analysis of all types of power electronic circuits. The Kirchoff's Laws and the Superposition theorem are applied by introducing the appropriate switching functions in order to derive Unified Expressions of voltage and current in switched circuits valid at all times. The exact expressions of the current in each semiconductor device in the circuit enables the circuit designer to collect all the relevant data to set the ratings of the device such as rms, average and peak values of voltage and current. The order of the voltage and current harmonics at any point in the circuit are derived with simple arithmetic. Compact expressions are derived for Sinusoidal PWM signals based on the switching function. The order, magnitude and phase of each component are derived directly from the expression with simple arithmetic. The educator has a simple way to present to his students the mechanism of operation of complex switched circuits where all the statements regarding their operation are actually presented in the model of the circuit.

Low Power and Low Voltage Circuit Design with the FGMOS Transistor

Tue, 12 Jun 2018 00:50:19 GMT

Motivated by consumer demand for smaller, more portable electronic devices that offer more features and operate for longer on their existing battery packs, cutting edge electronic circuits need to be ever more power efficient. For the circuit designer, this requires an understanding of the latest low voltage and low power (LV/LP) techniques, one of the most promising of which makes use of the floating gate MOS (FGMOS) transistor.

Whilst a conventional MOS transistor has only one input, the FGMOS transistors often have several. This fact, along with some other remarkable properties of this very interesting device, offers the designer many extra degrees of freedom that can significantly improve power efficiency. By using FGMOS transistors in the right way – establishing appropriate relationships between their inputs - it is possible to achieve design trade-offs that are not possible with conventional MOS devices. This is especially true when power consumption and supply voltage are the main design constraints.

This book demonstrates how FGMOS transistors can be used in a low voltage and low power design context. The techniques shown provide innovative solutions, often in situations where the limits of the technology in question have been pushed far below the values recommended by the manufacturer.

Thermal Microwave Radiation

Mon, 11 Jun 2018 23:03:13 GMT

This book combines theoretical concepts with experimental results on thermal microwave radiation to advance the understanding of the complex nature of terrestrial media. With the emphasis on radiative transfer models the book covers the most urgent needs for the transition from the experimental phase of microwave remote sensing to operational applications. All terrestrial aspects are covered from the clear to the cloudy atmosphere, precipitation, ocean and land surfaces, vegetation, snow and ice.

A chapter on new results of microwave dielectric properties of natural media, covering wavelengths from the decimetre to the submillimetre range, will be a source for further radiative transfer developments, extending the applicability to radar and other electromagnetic tools, and including extraterrestrial objects, such as planets and comets.

The book resulted from a continued collaboration set up by the European COST Action No. 712 Application of Microwave Radiometry to Atmospheric Research and Monitoring (1996-2000). The aims of the action were to improve the application of microwave radiometry with emphasis on meteorology.

Sea Clutter

Mon, 11 Jun 2018 22:53:36 GMT

This book provides an authoritative account of the current understanding of radar sea clutter, describing its phenomenology, EM scattering and statistical modelling and simulation, and their use in the design of detection systems and the calculation and practical evaluation of radar performance.

The book pays particular attention to the compound K distribution model developed by the authors during the past 20 years. The evidence for this model, its mathematical formulation and development and practical application to the specification, design and evaluation of radar systems are all discussed. In addition, the book sets the previously empirical development of the K distribution model in the wider context of recent advances in the calculation of low grazing angle electromagnetic scattering and oceanographic modelling of the statistics of the sea surface.

The authors discuss in detail the prediction of the performance of specified radar systems; at the same time, their presentation of the underlying physical principles and analytic and computational techniques employed in these calculations is sufficiently comprehensive for the reader to be well equipped to tackle related problems with confidence.

These features, and appendices reviewing pertinent mathematical background material and the calculation of low grazing angle scattering by corrugated surfaces, make this book invaluable to specialist radar engineers and academic researchers, while being of considerable interest to the wider applied physics and mathematics communities.

Unmanned marine vehicles (UMVs) is a collective term used to describe autonomous underwater vehicles, remotely operated vehicles, semi-submersibles, and unmanned surface craft. Considerable interest has been shown in UMVs by the military, civilian and scientific communities due to their ability to undertake designated missions whilst either operating autonomously and/or on co-operation with other types of vehicle. Increasing importance is also being placed on the design and development of such vehicles as they are capable of providing cost effective solutions to a number of littoral, coastal and offshore problems. This book draws attention to the advanced technology which is evolving to meet the challenges being posed in this exciting and growing field of study.

Intelligent Distributed Video Surveillance Systems

Mon, 11 Jun 2018 20:55:40 GMT

There is a growing interest in the development and deployment of surveillance systems in public and private locations. Conventional approaches rely on the installation of wide area CCTV (Closed Circuit Television), but the explosion in the numbers of cameras that have to be monitored, the increasing costs of providing monitoring personnel and the limitations that humans have to maintain sustained levels of concentration severely limit the effectiveness of these systems. Advances in information and communication technologies, such as computer vision for face recognition and human behaviour analysis, digital annotation and storage of video, transmission of video/audio streams over wired and wireless networks, can potentially provide significant improvements in this field.

The book consists of a coherent selection of extended versions of presentations made in two successful IEE symposia on Intelligent Distributed Surveillance Systems (IDSS). It surveys recent development in distributed intelligent surveillance systems and brings together the work of researchers and engineers, system integrators and managers of public and private organisations likely to use such systems.
