Electromagnetic Field Standards and Exposure Systems

Electromagnetic field (EMF) measurements are among the least accurate of all measured phenomena. One of the most important factors limiting the accuracy of these measurements is the class of the EMF standards used. As the calibrated device cannot be more accurate than a standard applied to calibrate it, the need to improve the accuracy of the measurements requires an improvement of the EMF standards. This book should prove helpful to those looking to improve measurement accuracy. We present a range of factors that play an essential role in the estimation of the accuracy of the standards. However, there are no two identical standards, and

ПОЛИТИЧЕСКАЯ ФИЛОСОФИЯ И СОЦИОЛОГИЯ

Речь о проблемах и трудностях, стоящих перед полити ческой философией, представляется целесообразным начинать с рассуждения А. Шопенгауэра о философии в целом. Философия, писал он, это «высокая альпийская дорога; к ней ведет лишь крутая тропа чрез острые камни и колчие терния: она уединена и становится все пустыннее, чем выше восходишь, и кто идет по ней, пусть не ведает страха, все оставит за собою и смело прокладывает себе путь свой в холодном снегу.

Введение в геополитику

Важно учесть и то, что старая геополитика была разработана в период господства евроцентристского мира и в его интересах. Еще одна ее особенность состоит в том, что она базировалась на инфраструктуре Вестфальской системы международных отношений, которая, впрочем, тоже сформировалась и действовала в рамках евроцентристского мира.

Analysis and Design of Analog Integrated Circuits (6th Ed.)

Written in an accessible style to ensure complex content can be appreciated by both students and professionals, this Sixth Edition of Analysis and Design of Analog Integrated Circuits is a highly comprehensive textbook on analog design, offering in-depth coverage of the fundamentals of circuits in a single volume. To aid in reader comprehension and retention, supplementary material includes end of chapter problems, plus a Solution Manual for instructors. In addition to the well-established concepts, this Sixth Edition introduces a new super-source follower circuit and its large-signal behavior, frequency response, stability, and noise properties. New material also introduces replica biasing, describes and analyzes two op amps with replica biasing, and provides coverage of weighted zero-value time constants as a method to estimate the location of dominant zeros, pole-zero doublets (including their effect on settling time and three examples of circuits that create doublets), the effect of feedback on pole-zero doublets, and MOS transistor noise performance including a thorough treatment on thermally induced gate noise.

Fiber-Optic Communication Systems. 4th Edition

A communication system transmits information from one place to another, whether separated by a few kilometers or by transoceanic distances. Information is often carried by an electromagnetic carrier wave whose frequency can vary from a few megahertz to several hundred terahertz. Optical communication systems use high carrier frequencies (~ 100 THz) in the visible or near-infrared region of the electromagnetic spectrum. They are sometimes called lightwave systems to distinguish them from microwave systems, whose carrier frequency is typically smaller by five orders of magnitude (~ 1 GHz). Fiber-optic communication systems are lightwave systems that employ optical fibers for information transmission. Such systems have been deployed worldwide since 1980 and have revolutionized the field of telecommunications.

Behavioral Modelling and Predistortion of Wideband Wireless Transmitters

Wireless transmitters designed for modern communication systems are expected to handle wideband amplitude and phase modulated signals with three major performance metrics: linearity, bandwidth, and power efficiency. First, linearity requires the minimization of distortions mainly caused by the transmitter’s radio frequency (RF) analog circuitry in order to preserve the quality of the transmitted signal and avoid any loss of information during the transmission process. Second, bandwidth is critical for multi-carrier and multi-band communication systems. Moreover, wider bandwidths are needed to accommodate higher data rates. Third, power efficiency is an important consideration that affects the deployment and operating costs of communication infrastructure as well as environmental impact.

A JTL Study Book for the Electrotechnical Industry. Industry &Communication

This book looks at the overall communication network and structure of the industry that we work in. We’ll see what employers and the people that work for them do, where they do it and what rules, regulations and safe systems they have to follow while they are doing it. We’ll discover how important it is to successfully deal with other people, whether in conversation or through the use of written information and go on to look at the different types of information that we are likely to come across in the course of our work. The book also outlines current thinking regarding career and employment development within the electrotechnical industry.

Road Vehicles Surroundings Supervision: On-Board Sensors and Communications

This Special Issue presents a selection of current solutions for vehicle surroundings perception systems. This perception is essential for many advanced driver application systems and autonomous driving, and there are currently several challenges that need addressing. Perception can be obtained using on-board sensors, but, due to their limitations, the development of sensor fusion techniques or specific algorithms is needed. Vehicle positioning is also important, but further refined accuracy and specific requirements arise with each new application. Apart from on-board sensors, wireless communication can provide information from a larger electronic horizon that can be used for better decision making. Finally, all this information can be used to enhance development of autonomous driving.
