A GUIDE TO THE FUNDAMENTAL THEORY AND PRACTICE OF OPTICAL COMMUNICATION Fiber Optic and Atmospheric Optical Communication offers a much needed guide to characterizing and overcoming the drawbacks associated with optical communication links that suffer from various types of fading when optical signals with information traverse these wireless (atmospheric) or wired (fiber optic) channels. The authors—noted experts on the topic—present material that aids in predicting the capacity, data rate, spectral efficiency, and bit-error-rate associated with a channel that experiences fading. They review modulation techniques and methods of coding and decoding that are useful when implementing communications systems. The book also discusses how to model the channels, including treating distortion due to the various fading phenomena. Light waves and their similarity to radio waves are explored, and the way light propagates through the atmosphere, through materials, and through the boundary between two materials is explained. This important book: Characterizes principal optical sources and detectors, including descriptions of their advantages and disadvantages, to show how to design systems from start to finish Provides a new method of predicting and dealing with the dispersive properties of fiber optic cables and other optical guiding structures in order to increase data stream capacity Highlights effects of material and multimode (multi-ray) dispersion during propagation of optical signals with data through fiber optic channels Presents modulation techniques and methods of coding and decoding that are useful when implementing communications systems Written for professionals dealing with optical and electro-optical communications, Fiber Optic and Atmospheric Optical Communication explores the theory and practice of optical communication both when the optical signal is propagating through the atmosphere and when it is propagating through an optical fiber.
Understanding the nature of random signals and noise is critically important for detecting signals and for reducing and minimizing the effects of noise in applications such as communications and control systems. Outlining a variety of techniques and explaining when and how to use them, Random Signals and Noise: A Mathematical Introduction focuses on applications and practical problem solving rather than probability theory. A Firm Foundation Before launching into the particulars of random signals and noise, the author outlines the elements of probability that are used throughout the book and includes an appendix on the relevant aspects of linear algebra. He offers a careful treatment of Lagrange multipliers and the Fourier transform, as well as the basics of stochastic processes, estimation, matched filtering, the Wiener-Khinchin theorem and its applications, the Schottky and Nyquist formulas, and physical sources of noise. Practical Tools for Modern Problems Along with these traditional topics, the book includes a chapter devoted to spread spectrum techniques. It also demonstrates the use of MATLAB® for solving complicated problems in a short amount of time while still building a sound knowledge of the underlying principles. A self-contained primer for solving real problems, Random Signals and Noise presents a complete set of tools and offers guidance on their effective application.
A mathematically rigorous but accessible treatment of digital signal processing that intertwines basic theoretical techniques with hands-on laboratory instruction is provided by this book. The book covers various aspects of the digital signal processing (DSP) "problem". It begins with the analysis of discrete-time signals and explains sampling and the use of the discrete and fast Fourier transforms. The second part of the book — covering digital to analog and analog to digital conversion — provides a practical interlude in the mathematical content before Part III lays out a careful development of the Z-transform and the design and analysis of digital filters.
The 3rd edition strikes a nice balance between mathematical rigor and engineering oriented applications, helping students to understand the mathematical and engineering aspects of control theory.The book makes effective use of the tools provided by MATLAB® (and includes material about using the tools provided by the Python® programming language) in the design and analysis of control systems without allowing the computer-based tools to substitute for knowledge of control theory. The examples in the text are carefully designed to develop the student's intuition — in both mathematics and engineering.With over 90 solved homework problems and about 200 figures, this invaluable title will benefit junior and senior level university students in engineering.
For more than 65 years, Williams Textbook of Endocrinology has been the gold standard in the field, delivering authoritative guidance on every aspect of adult and pediatric endocrine system disorders. The 13th Edition has been thoroughly updated by Drs. Shlomo Melmed, Kenneth S. Polonsky, P. Reed Larsen, and Henry M. Kronenberg, to bring you state-of-the-art coverage of diabetes, metabolic syndrome, obesity, thyroid disease, testicular disorders, and much more, all designed to help you provide optimal care to every patient. Bridging the gap between basic science and clinical information, it is an essential, relevant resource for endocrinologists, endocrine surgeons, gynecologists, internists, and pediatricians – any clinician who needs the most reliable coverage available on the diverse features across the spectrum of endocrine disease. Obtain a better understanding of both scientific insight and clinical data from the classic reference that delivers the current information you need in a highly illustrated, user-friendly format. Stay up to date with expanded discussions of autoimmune thyroid diseases, mechanisms, and the appropriate treatment of the ophthalmopathy of Graves’ disease; a new section on the interpretation of fine needle aspiration results in patients with thyroid nodules; and new coverage of when and when not to use radioiodine in the treatment of patients with thyroid cancer. Update your knowledge and skills with all-new chapters on Genetics of Endocrine Disease, Endocrinology of Population Health, and Laboratory Techniques for Recognition of Endocrine Disorders. Confidently manage any clinical endocrinopathy you may encounter thanks to new information on recent FDA-approved drugs for pituitary disorders, a new focus on pediatrics, and new content on diabetes, obesity, and appetite control. Benefit from the expertise of dynamic new contributors who offer fresh perspectives throughout.

Striking a nice balance between mathematical rigor and engineering-oriented applications, this second edition covers the bedrock parts of classical control theory — the Routh-Hurwitz theorem and applications, Nyquist diagrams, Bode plots, root locus plots, and the design of controllers (phase-lag, phase-lead, lag-lead, and PID). It also covers three more advanced topics — non-linear control, modern control, and discrete-time control.This invaluable book makes effective use of MATLAB® as a tool in design and analysis. Containing 75 solved problems and 200 figures, this edition will be useful for junior and senior level university students in engineering who have a good knowledge of complex variables and linear algebra.

We all live with a deeply rooted desire to understand our unique purpose in this world. That discovery is the key to making every moment meaningful and living a truly empowered life. But are we searching in the right places? The Four Elements of an Empowered Life takes you on a journey inward — to understand your unique purpose and to discover your inner worlds, represented by the four elements of fire, wind, water, and earth. Drawing on a wide range of sources, including classic Torah texts, Kabbalistic works, psychology, and modern-day thinkers, as well as the author’s own personal experiences in Jewish education and outreach, Rabbi Buxbaum presents a close-up look at the constant struggles that are taking place within each of these inner worlds. These pages are filled with practical tools and habits that will help you master the elements and become the greatest possible version of yourself — empowering you to accomplish the mission that only you can achieve in this world.
In 1967, Rabbi Shlomo Carlebach established the House of Love and Prayer, an outreach center for Jewish spiritual seekers located in San Francisco. One of its activities was the publication of The Holy Beggars' Gazette, a gathering of Jewish wisdom authored by Reb Shlomo and others. This book brings together the contents of The Holy Beggars' Gazette, and is presented chronologically from its beginnings in 1972 until it ceased publication in 1979.
