Five Decades of Tackling Models for Stiff Fluid Dynamics Problems: A Scientific Autobiography

by Radyadour Kh. Zeytounian

Rationality - as opposed to 'ad-hoc' - and asymptotics - to emphasize the fact that perturbative methods are at the core of the theory - are the two main concepts associated with the Rational Asymptotic Modeling (RAM) approach in fluid dynamics when the goal is to specifically provide useful models accessible to numerical simulation via high-speed computing. This approach has contributed to a fresh understanding of Newtonian fluid flow problems and has opened up new avenues for tackling real fluid flow phenomena, which are known to lead to very difficult mathematical and numerical problems irrespective of turbulence. With the present scientific autobiography the author guides the reader through his somewhat non-traditional career; first discovering fluid mechanics, and then devoting more than fifty years to intense work in the field. Using both personal and general historical contexts, this account will be of benefit to anyone interested in the early and contemporary developments of an important branch of theoretical and computational fluid mechanics.

Fixed Broadband Wireless System Design

by Harry R. Anderson

Fixed broadband networks can provide far higher data rates and capacity than the currently envisioned 3G and 4G mobile cellular systems. Achieving higher data rates is due to the unique technical properties of fixed systems, in particular, the use of high gain and adaptive antennas, wide frequency bands, dynamic data rate and channel resource allocation, and advanced multiple access techniques. Fixed Broadband Wireless System Design is a comprehensive presentation of the engineering principles, advanced engineering techniques, and practical design methods for planning and deploying fixed wireless systems, including: Point-to-point LOS and NLOS network design Point-to-point microwave link design including active and passive repeaters Consecutive point and mesh network planning Advanced empirical and physical propagation modeling including ray-tracing Detailed microwave fading models for multipath and rain NLOS (indoor and outdoor) propagation and fading models Propagation environment models including terrain, morphology, buildings, and atmospheric effects Novel mixed application packet traffic modeling for dimensioning network capacity Narrow beam, wide beam, and adaptive (smart) antennas MIMO systems and space-time coding Channel planning including fixed and dynamic channel assignment and dynamic packet assignment IEEE 802.11b and 802.11a (WLAN) system design Free space optic (FSO) link design At present, there are no titles available that provide such a concise presentation of the wide variety of systems, frequency bands, multiple access techniques, and other factors that distinguish fixed wireless systems from mobile wireless systems. Fixed Broadband Wireless System Design is essential reading for design, system and RF engineers involved in the design and deployment of fixed broadband wireless systems, fixed wireless equipment vendors, and academics and postgraduate students in the field.

Fixed Interval Smoothing for State Space Models (The Springer International Series in Engineering and Computer Science #609)

by Howard L. Weinert

Fixed-interval smoothing is a method of extracting useful information from inaccurate data. It has been applied to problems in engineering, the physical sciences, and the social sciences, in areas such as control, communications, signal processing, acoustics, geophysics, oceanography, statistics, econometrics, and structural analysis. This monograph addresses problems for which a linear stochastic state space model is available, in which case the objective is to compute the linear least-squares estimate of the state vector in a fixed interval, using observations previously collected in that interval. The author uses a geometric approach based on the method of complementary models. Using the simplest possible notation, he presents straightforward derivations of the four types of fixed-interval smoothing algorithms, and compares the algorithms in terms of efficiency and applicability. Results show that the best algorithm has received the least attention in the literature. Fixed Interval Smoothing for State Space Models: includes new material on interpolation, fast square root implementations, and boundary value models; is the first book devoted to smoothing; contains an annotated bibliography of smoothing literature; uses simple notation and clear derivations; compares algorithms from a computational perspective; identifies a best algorithm. Fixed Interval Smoothing for State Space Models will be the primary source for those wanting to understand and apply fixed-interval smoothing: academics, researchers, and graduate students in control, communications, signal processing, statistics and econometrics.

Fixed Mobile Convergence Handbook

by Syed A. Ahson Mohammad Ilyas

Requirements for next generation networks (NGNs) are fueling an architectural evolution. Service providers are obliged to give users access to content anytime, anyhow, anywhere, on any device. This requires a converged infrastructure in which users across multiple domains can be served through a single unified domain and all network services and business units can be consolidated on a single IP infrastructure. The Fixed Mobile Convergence Handbook is a comprehensive guide to the design, implementation, and management of converged cellular/WiFi wireless networks. This book discusses how FMC is transforming technologies as multimedia ceases to be passively consumed and unidirectional—and becomes increasingly mobile, personalized and interactive. This book also describes ways to ensure that networks remain cost-effective, scalable, reliable, and secure in the face of constant technological evolution. This material encapsulates the state of FMC, covering everything from basic concepts to research-grade material and future directions. Addressing a broad range of topics, the handbook consists of 16 chapters authored by 44 experts from around the world. Subjects include: Femtocell network technology and applications Deployment modes and interference avoidance Architecture for power efficiency Conversational quality and network planning Design of SIP-based mobility management protocols Highly respected in their field, the authors anticipate the key issues and problems that FMC presents—from application inception and deployment to system interconnection and Quality of Service (QoS). Ideal for professional mobile technology designers and/or planners, researchers (faculty members and graduate students), this book provides specific salient features and information that will guide innovation in the 21st century and beyond.

Fixed-Point Signal Processing (Synthesis Lectures on Signal Processing)

by Wayne Padgett David Anderson

This book is intended to fill the gap between the ""ideal precision"" digital signal processing (DSP) that is widely taught, and the limited precision implementation skills that are commonly required in fixed-point processors and field programmable gate arrays (FPGAs). These skills are often neglected at the university level, particularly for undergraduates. We have attempted to create a resource both for a DSP elective course and for the practicing engineer with a need to understand fixed-point implementation. Although we assume a background in DSP, Chapter 2 contains a review of basic theory and Chapter 3 reviews random processes to support the noise model of quantization error. Chapter 4 details the binary arithmetic that underlies fixed-point processors and then introduces fractional format for binary numbers. Chapter 5 covers the noise model for quantization error and the effects of coefficient quantization in filters. Because of the numerical sensitivity of IIR filters, they are used extensively as an example system in both Chapters 5 and 6. Fortunately, the principles of dealing with limited precision can be applied to a wide variety of numerically sensitive systems, not just IIR filters. Chapter 6 discusses the problems of product roundoff error and various methods of scaling to avoid overflow. Chapter 7 discusses limit cycle effects and a few common methods for minimizing them. There are a number of simple exercises integrated into the text to allow you to test your understanding. Answers to the exercises are included in the footnotes. A number of MATLAB examples are provided in the text. They generally assume access to the Fixed-Point Toolbox. If you lack access to this software, consider either purchasing or requesting an evaluation license from The Mathworks. The code listed in the text and other helpful MATLAB code is also available at http://www.morganclaypool.com/page/padgett and http://www.rose-hulman.edu/padgett/fpsp. You will also find MATLAB exercises designed to demonstrate each of the four types of error discussed in Chapters 5 and 6. Simulink examples are also provided on the web site.

Fixed-Time Cooperative Control of Multi-Agent Systems

by Qing-Long Han Zongyu Zuo Boda Ning

This monograph presents new theories and methods for fixed-time cooperative control of multi-agent systems. Fundamental concepts of fixed-time stability and stabilization are introduced with insightful understanding. This book presents solutions for several problems of fixed-time cooperative control using systematic design methods. The book compares fixed-time cooperative control with asymptotic cooperative control, demonstrating how the former can achieve better closed-loop performance and disturbance rejection properties. It also discusses the differences from finite-time control, and shows how fixed-time cooperative control can produce the faster rate of convergence and provide an explicit estimate of the settling time independent of initial conditions. This monograph presents multiple applications of fixed-time control schemes, including to distributed optimization of multi-agent systems, making it useful to students, researchers and engineers alike.

The Fixer

by Joseph Finder

What secrets are his family keeping? A month ago, Rick Hoffman was a popular journalist. Now, having being fired by his magazine, he is penniless and alone. At least he still has keys to his father's house, which has been empty since he moved to a nursing home after a stroke. There, hidden in the walls of his father's attic, Rick finds something that could change his life: bundles of cash worth millions. He knows he shouldn't spend it without asking where it came from. But his bed-bound father can no longer speak. What Rick doesn't realise is that, if he could, he'd tell his son just how much danger he is in... Recent reviews for Joseph Finder: 'Stunning...

Fjords: Processes and Products

by James P.M. Syvitski David C. Burrell Jens M. Skei

Fjords are both an interface and a buffer between glaciated continents and the oceans. They exhibit a very wide range in environmental conditions, both in dynamics and geography. Some are truly wonders of the world with their dizzying mountain slopes rising sharply from the ocean edge. Others represent some of the harshest conditions on earth, with hurricane winds, extremes in temperature, and catastrophic earth and ice movements. Fjords are unique estuaries and represent a large portion of the earth's coastal zone. Yet they are not very well known, given the increasing population and food pressures, and their present industrial and strategic importance. Temperate­ zone estuaries have had many more years of intense study, with multiyear data available. Most fjords have not been impacted by man but, if history repeats itself, that condition will not last long. Fjords present some unique environmental problems, such as their usually slow flushing time, a feature common to many silled environments. Thus there is presently a need for management guidelines, which can only be based on a thorough knowledge of the way fjords work. Fjords are, in many respects, perfect natural oceanographic and geologic lab­ oratories. Source inputs are easily identified and their resulting gradients are well developed. Throughout this book, we emphasize the potential of modeling pro­ cesses in fjords, with comparisons to other estuary, lake, shelf and slope, and open ocean environments.

Flächentragwerke: Einführung in die Elastostatik der Scheiben, Platten, Schalen und Faltwerke

by Karl Girkmann

Das vorliegende Buch behandelt die Berechnung von Flächentrag­ werken. Es sind dies dünnwandige, nach Flächen geformte Traggebilde. Ihre Mittelfläche - jene Fläche, die an jeder Stelle die Dicke halbier- kann eben sein, sie kann einfach oder doppelt gekrümmt sein, und sie kann aus ebenen und gekrümmten Teilflächen zusammengesetzt sein. Ein ebener Flächenträger, der nur durch Kräfte belastet ist, die in seiner Ebene wirken, wird Scheibe genannt. Greifen auch (oder ausschließlich) quer zur Mittelebene gerichtete Kräfte an, dann wird der ebene Flächen­ träger als Platte bezeichnet. Ist die Mittelfläche eines Flächentragwerkes gekrümmt oder aus gekrümmten und ebenen Teilflächen zusammengesetzt, dann sprechen wir von einer Schale bzw. einem Schalentragwerk. Wird die Mittelfläche nur von ebenen Teilflächen gebildet, dann wird das Trag­ werk Faltwerk genannt. Alle angeführten Bauformen, einschließlich der Scheiben und Platten, werden unter dem Titel Flächentragwerke zu­ sammengefaßt. In der Regel müssen diese Tragwerke bereits nach der Theorie der mehrdimensionalen Systeme berechnet werden. Beim Entwurf von Tragwerken des Stahl- und des Stahlbetonbaues ist es nun häufig notwendig, einzelne Bauglieder als Flächentragwerke aufzufassen, um die Größe und den Verlauf der inneren Kräfte hin­ reichend genau ermitteln zu können. Im Stahlbau sind es verschiedene wichtige Krafteinleitungs- und Kraftverteilungsprobleme, Stabilitäts­ untersuchungen für dünne Bleche, Probleme des Zusammenwirkens von stab- und plattenförmigen BaugIiedern, Behälteraufgaben usw. , die in dieser Weise behandelt werden müssen.
