This textbook presents the elements of applied aerodynamics and aeronautical engineering which relate directly to flight training and general flight operations. Originally published by the U.S. Navy and revised in 1965. A long-established U.S. Navy publication also used by the U.S. Air Force as well as by the FAA as a source reference for their own publications, for more than 50 years this textbook has been a definitive source that communicates the complexities of applied aerodynamics and aeronautical engineering for both the beginner and the experienced pilot. Flight safety and effectiveness depends greatly on the understanding and appreciation of how and why an airplane flies, and this resource teaches aerodynamic principles, providing the foundation for developing precise flying techniques and operational procedures. The information in "Aerodynamics for Naval Aviators" is applicable to flight training, transition training, reciprocating and turbine-powered airplanes, and general flying operations. It offers the elements of both theory and application, covering basic aerodynamics, high-speed aerodynamics, airplane performance, stability and control, operation strength limitations, and the application of aerodynamics to specific problems of flying, such as the region of reversed command, wind shear, effects of ice and frost, ground effect, and collision avoidance. Also included are an index and a list of selected references.

This book offers a general overview of the physics, concepts, theories, and models underlying the discipline of aerodynamics. A particular focus is the technique of velocity field representation and modeling via source and vorticity fields and via their sheet, filament, or point-singularity idealizations. These models provide an intuitive feel for aerodynamic flow-field behavior and are the basis of aerodynamic force analysis, drag decomposition, flow interference estimation, and other important applications. The models are applied to both low speed and high speed flows. Viscous flows are also covered, with a focus on understanding boundary layer behavior and its influence on aerodynamic flows. The book covers some topics in depth while offering introductions and summaries of others. Computational methods are indispensable for the practicing aerodynamicist, and the book covers several computational methods in detail, with a focus on vortex lattice and panel methods. The goal is to improve understanding of the physical models that underlie such methods. The book also covers the aerodynamic models that describe the forces and moments on maneuvering aircraft, and provides a good introduction to the concepts and methods used in flight dynamics. It also offers an introduction to unsteady flows and to the subject of wind tunnel measurements. The book is based on the MIT graduate-level course "Flight Vehicle Aerodynamics" and has been developed for use not only in conventional classrooms but also in a massive open online course (or MOOC) offered on the pioneering MOOC platform edX. It will also serve as a valuable reference for professionals in the field. The text assumes that the reader is well versed in basic physics and vector calculus, has had some exposure to basic fluid dynamics and aerodynamics, and is somewhat familiar with aerodynamics and aeronautics terminology.

Opis - Pierwsze na świecie świadectwo ofiary zbrodni honorowej. Miała siedemnaście lat i zakochała się: zhańbiła rodzinę. Więc rodzina wydała na nią wyrok śmierci... Pokochała go pierwszą miłością. Myślała, że się z nią ożeni. Ale ukochany zniknął, a ona odkryła, że jest w ciąży. A w jej świecie to najcięższa zbrodnia... W zapomnianej przez Boga wiosce w Cisjordanii kobiety są warte mniej niż zwierzęta domowe. Tu mężczyzna jest panem życia i śmierci żony, córki, siostry. Brat może bezkarnie zabić siostrę, matka - córkę, kolejną bezużyteczną dziewczynkę, jaka się urodzi. Tu kobiecie odbiera się godność, a nawet życie zgodnie z odwiecznym obyczajem i uświęconą tradycją. A śmierć jest karą dla dziewczyny, która zhańbi rodzinę. Tak jak Souad. Wyrok wydaje jej ojciec. Szwagier dokonuje egzekucji. Oblewa Souad benzyną i podpala... SOUAD przeżyła - cudem, ale rodzina usiłowała zabić ją nawet w szpitalu. Na zawsze jednak pozostanie straszliwie okaleczona - na ciele i duszy. I wciąż musi się ukrywać; dopóki żyje, jej rodzinę okrywa hańba. Spalona żywcem, opublikowana pod pseudonimem szokująca opowieść o piekle, jakim było jej dzieciństwo i młodość, stała się międzynarodowym bestsellerem. Wydana w 37 w krajach książka przerywa tabu milczenia wobec istniejącej nadal w krajach muzułmańskich barbarzyńskiej tradycji. Nieludzkiego obyczaju, prawa mężczyzn, na mocy którego co najmniej pięć tysięcy kobiet pada co roku ofiarą zbrodni honorowej. Nazwa - Spalona Żywcem Wyd.

This book introduces turbo error correcting concept in a simple language, including a general theory and the algorithms for decoding turbo-like code. It presents a unified framework for the design and analysis of turbo codes and LDPC codes and their decoding algorithms.§A major focus is on high speed turbo decoding, which targets applications with data rates of several hundred million bits per second (Mbps).The advent of turbo codes has sparked tremendous research activities around the theoretical and practical aspects of turbo codes and turbo-like codes. The crucial novelty in these codes is the iterative decoding.§Turbo-like Codes introduces turbo error correcting concept in a simple language, including a general theory and the algorithms for decoding turbo-like code. It presents a unified framework for the design and analysis of turbo codes and LDPC codes and their decoding algorithms.§A major focus of Turbo-like Codes is on high speed turbo decoding, which targets applications with data rates of several hundred million bits per second (Mbps). In this book a novel high-speed turbo decoder is presented that exploits parallelization. Parallelism is achieved very efficiently by exploiting the flexibility of message-passing algorithm. It has been shown that very large speed gains can be achieved by this scheme while the efficiency is maintained reasonably high. Memory access, which poses a practical problem for the proposed parallel turbo decoder, is solved by introducing the conflict-free interleaver. The latency is further improved by designing a special kind of conflict-free interleaver. Furthermore, an algorithm to design such interleaver is presented. It is shown that the performance of turbo code is not sacrificed by using the interleaver with the proposed structure.§Although turbo code has near Shannon-capacity performance and the proposed architecture for parallel turbo decoder provides a very efficient and highly regular hardware, the circuit is still very complex and demanding for very high-speed decoding. Therefore, the next step would be finding turbo-like codes that not only achieve excellent error correction capability, but also are very simple. As a result, a class of new Low-Density Parity-Check (LDPC) codes for different rates and block-sizes, called Accumulate-Repeat-Accumulate (ARA) codes, is presented. The performance of ARA codes is analyzed and shown that some ARA codes perform very close to random codes, which achieve Shannon limit.

Introduction to Ultrasonic Motors Clarendon Press

Książki / Literatura obcojęzyczna

The ultrasonic motor, invented in 1980, utilizes the piezoelectric effect in the ultrasonic frequency range to provide the motive force. (In conventional electric motors the motive force is electromagnetic). The result is a motor with unusually good low-speed high-torque and power-to-weight characteristics. It has already found applications in camera autofocus mechanisms, medical equipment subject to high magnetic fields, and motorized car accessories. Its applications will increase as designers become more familiar with its unique characteristics. This book is the result of a collaboration between the inventor and an expert in conventional electric motors: the result is an introduction to the general theory presented in a way that links it to conventional motor theory. It will be invaluable both to motor designers and to those who design with and use electric motors as an introduction to this important new invention.
