Fiber-optic communication systems have revolutionized our telecommunication infrastructures – currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information – only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored. As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK sig

For the first time in power electronics, this comprehensive treatment of switch-mode DC/DC converter designs addresses many analytical closed form equations such as duty cycle prediction, output regulation, output ripple, control loop-gain, and steady state time-domain waveform. Each of these equations are given various topologists and configurations, including forward, flyback, and boost converters. Pulse Width Modulated DC/DC Converters begins with a detailed approach to the quiescent operating locus of a power plant under open-loop. The reader is then led through other supporting

This book studies switch-mode power supplies (SMPS) in great detail. This type of converter changes an unregulated DC voltage into a high-frequency pulse-width modulated (PWM) voltage controlled by varying the duty cycle, then changes the PWM AC voltage to a regulated DC voltage at a high efficiency by rectification and filtering. Used to supply electronic circuits, this converter saves energy and space in the overall system.With concept-orientated explanations, this book offers state-of-the-art SMPS technology and promotes an understanding of the principle operations of PWM converters, as wel

In the late medieval era, pain could be a symbol of holiness, disease, sin, or truth. It could be encouragement to lead a moral life, a punishment for wrong doing, or a method of healing. Exploring the varied depictions and descriptions of pain—from martyrdom narratives to practices of torture and surgery—The Modulated Scream attempts to decode this culture of suffering in the Middle Ages. Esther Cohen brings to life the cacophony of howls emerging from the written record of physicians, torturers, theologians, and mystics. In considering how people understood suffering, explained it

The primary objective of this book is to teach residents, fellows, and clinicians in radiation oncology how to incorporate intensity modulated radiation therapy (IMRT) into their practice. IMRT has proven to be an extremely effective treatment modality for head and neck cancers. It is now being used effectively in other sites, including, prostate, breast, lung, gynecological, the cervix, the central nervous system, and lymph nodes. The book will provide in a consistent format an overview of the natural course, lymph node spread, diagnostic criteria, and therapeutic options for each cancer subs

A study of modulated coding (MC), a technique for intersymbol interference (ISI) mitigation. It discusses MC when the ISI is known at both transmitter and receiver, and when only the receiver knows the ISI. It showcases polynomial antiquity resistant modulated coding, and provides an examination of transmitter-assisted ISI equalization.

This work effectively responds to the pressing need for a clinically-oriented textbook that focuses on all aspects of intensity modulated radiation therapy (IMRT). Intensity Modulated Radiation Therapy: A Clinical Perspective is divided into three sections: Fundamentals, Clinical Implementation, and Clinical Sites. The book aims to provide a practical approach oriented text for radiation oncologists and physicists interested in commencing or expanding an IMRT program. It discusses the fundamentals of IMRT including physics and biology and provides a site-by-site review (i.e. breast, prostate,
