Latest research indicates that construction of a communal meaning regarding coordination of complex systems development tasks should be implemented into practice, proving that far more attention should be given to the issue of communal meaning construction in organizations. Using Activity Domain Theory for Managing Complex Systems offers a new approach towards managing complex systems that informs the co-construction of technical support for coordination and communal meaning regarding this support. Compiling and structuring empirical observations from the Ericsson Company and theoretical developments from the perspective of meaning construction, this unique book combines a deep understanding of concrete, every-day conditions of the telecom industry with innovative theoretical development of the Activity Domain Theory (ADT).

Uniquely explains in detail how small antennas work and ways to improve their performance

This book addresses the recent significant theoretical and practical developments in the electrically small antenna (ESA) area. Examining antenna designs that work as well as those that have limitations, it offers the latest information on electromagnetically coupled structures and improving bandwidth using spherical helix dipoles, the exact derivation of Q for electrically small antennas for both TE and TM modes, a new simplified Q formula developed by the authors, and discussions of metamaterials and computer model accuracy for ESA.

The book begins with detailed electromagnetic derivations of Chu and Thal Q formulations, formulas for Q when U or E cores are used, and effects of loss on Q. It also includes a treatise on bandwidth and matching, and Foster's reactance theorem, as well as up-to-date coverage of canonical antennas: dipoles, loops, self-resonant ESA, PIFA, and dielectric resonator antennas.

Just as this book offers the concrete facts on relevant developments in the field, it also clears up confusion regarding findings that have not turned out to be useful. Presented here are antenna ideas that are clever but with performance numbers that are poor, as well as eighteen more antenna ideas that are simply not to be believed. The book concludes with recent data on the use of self-resonant elements in superdirective antennas and new delay line data on superconducting antennas.

Each chapter features extensive references and an author list. In addition, helpful appendices cover a world history of ESA, antenna terms important to ESA, a paper on NIM shells enclosing an ESA dipole, and analytical errors associated with perfect lenses and sub-wavelength focusing. Small Antenna Handbook is ideal for practicing engineers in the telecommunications and national defense areas, as well as for upper-level undergraduate and graduate students.

This book offers an intuitive approach to random processes and educates the reader on how to interpret and predict their behavior. Premised on the idea that new techniques are best introduced by specific, low-dimensional examples, the mathematical exposition is easier to comprehend and more enjoyable, and it motivates the subsequent generalizations. It distinguishes between the science of extracting statistical information from raw data--e.g., a time series about which nothing is known a priori--and that of analyzing specific statistical models, such as Bernoulli trials, Poisson queues, ARMA, and Markov processes. The former motivates the concepts of statistical spectral analysis (such as the Wiener-Khintchine theory), and the latter applies and interprets them in specific physical contexts. The formidable Kalman filter is introduced in a simple scalar context, where its basic strategy is transparent, and gradually extended to the full-blown iterative matrix form.

This textbook is based on 20 years of teaching a graduate-level course in random processes to a constituency extending beyond signal processing, communications, control, and networking, and including in particular circuits, RF and optics graduate students. In order to accommodate today's circuits students' needs to understand noise modeling, while covering classical material on Brownian motion, Poisson processes, and power spectral densities, the author has inserted discussions of thermal noise, shot noise, quantization noise and oscillator phase noise. At the same time, techniques used to analyze modulated communications and radar signals, such as the baseband representation of bandpass random signals, or the computation of power spectral densities of a wide variety of modulated signals, are presented. This book also emphasizes modeling skills, primarily through the inclusion of long problems at the end of each chapter, where starting from a description of the operation of a system, a model is constructed and then analyzed. Provides semester-length coverage of random processes, applicable to the analysis of electrical and computer engineering systems; Designed to be accessible to students with varying backgrounds in undergraduate mathematics and engineering; Includes solved examples throughout the discussion, as well as extensive problem sets at the end of every chapter; Develops and reinforces student's modeling skills, with inclusion of modeling problems in every chapter; Solutions for instructors included.
