Vibrator and Slot Antenna Arrays for Modern Applications (Lecture Notes in Electrical Engineering #1244)
by Victor A. Katrich Sergey L. Berdnik Mikhail V. Nesterenko Oleksandr M. Dumin Anatoliy I. Luchaninov Dmitriy V. GretskihThis book provides solutions to a complex of internal and external problems of electromagnetics associated with the development of theory, construction of mathematical models and the development of rigorous methods for calculating the electrodynamic characteristics of radiating structures and antenna arrays with impedance vibrator and slot elements. The issues related to the impedance synthesis of antenna arrays and analysis of large-aperture rectenna arrays are considered. Solutions to the problems of determining the electrodynamic characteristics of impedance vibrators, slot and multi-element radiators with arbitrary geometric and electrophysical parameters are obtained within the framework of a unified methodological approach to constructing asymptotic solutions of integral equations for currents. This approach made it possible to study a number of new vibrator, slotted, and combined vibrator-slotted structures and their multi-element systems. The original research results reveal the possibilities of using such structures as basic elements for creating modern antenna-waveguide devices operating in the range from meter to millimeter wavelengths which have new technical characteristics and functionalities. This book is intended for senior and postgraduate students and researchers working in the fields of radiophysics, radio engineering and antenna-feeder design. The book covers the following topics: Excitation of Electromagnetic Fields in Electrodynamic Volumes with Coordinate Boundaries General Aspects of the Theory of Thin Impedance Vibrators and Narrow Slots in a Quasi-One-Dimensional Approximation Impedance Vibrators Antenna Arrays Slotted Waveguide Antenna Arrays Combined Vibrator-Slot Antenna Arrays Impedance Synthesis for Vibrator Antenna Arrays Impedance Synthesis for Slot Antenna Arrays Large-Aperture Rectenna Arrays of Wireless Power Transmission Systems Ultrawideband Combined Vibrator-Slot Antenna Arrays

Vibro-Acoustics, Volume 1
by Anders Nilsson Bilong LiuThis three-volume book gives a thorough and comprehensive presentation of vibration and acoustic theories. Different from traditional textbooks which typically deal with some aspects of either acoustic or vibration problems, it is unique of this book to combine those two correlated subjects together. Moreover, it provides fundamental analysis and mathematical descriptions for several crucial phenomena of Vibro-Acoustics which are quite useful in noise reduction, including how structures are excited, energy flows from an excitation point to a sound radiating surface, and finally how a structure radiates noise to a surrounding fluid. Many measurement results included in the text make the reading interesting and informative. Problems/questions are listed at the end of each chapter and the solutions are provided. This will help the readers to understand the topics of Vibro-Acoustics more deeply. The book should be of interest to anyone interested in sound and vibration, vehicle acoustics, ship acoustics and interior aircraft noise. This is the first volume, and covers the following topics: Mechanical systems with one degree of freedom, Frequency domain, Waves in solids, Interaction between longitudinal and transverse waves, General wave equation, Wave attenuation due to losses and transmission across junctions, Longitudinal vibrations of finite beams, Flexural vibrations of finite beams, Flexural vibrations of finite plates.
Vibro-Acoustics: Fundamentals and Applications
by Dhanesh N. ManikThe subject of vibro-acoustics is important for the design of machine elements and structures, to minimize sound generated by them. For better machine designing, it is necessary for machine designers (mechanical engineers) to have a thorough knowledge of vibro-acoustics. Furthermore, since the design cycles of machines have become shorter, designers will have to design quiet machines at the drawing-board stage rather than applying "band-aid" techniques after the machine has been built. Although there is common ground in the treatment of acoustics, the subject of vibration is not very fortunate. Those interested in low-frequency vibration are generally concerned with the modal approach of using natural frequencies and mode shapes, whereas those interested in vibro-acoustics in medium and high frequencies are generally concerned with the wave approach. Since both modal and wave approaches have their advantages, it is a good idea to study both together to get the best out of them. This is useful for a better understanding the physics of vibro-acoustics. Written for students and professionals interested in gaining knowledge, this book systematically integrates the relevant aspects of vibro-acoustics from various viewpoints.
Vibroacoustic Simulation: An Introduction to Statistical Energy Analysis and Hybrid Methods
by Alexander PeifferVIBROACOUSTIC SIMULATION Learn to master the full range of vibroacoustic simulation using both SEA and hybrid FEM/SEA methods Vibroacoustic simulation is the discipline of modelling and predicting the acoustic waves and vibration of particular objects, systems, or structures. This is done through finite element methods (FEM) or statistical energy analysis (SEA) to cover the full frequency range. In the mid-frequency range, both methods must be combined into a hybrid FEM/SEA approach. By doing so, engineers can model full frequency vibroacoustic simulations in complex technical systems used in aircraft, trains, cars, ships, and satellites. Indeed, hybrid approaches are increasingly used in the automotive, aerospace, and rail industries. Previously covered primarily in scientific journals, Vibroacoustic Simulation provides a practical approach that helps readers master the full frequency range of vibroacoustic simulation. Through a systematic approach, the book illustrates why both FEM and SEA are necessary in acoustic engineering and how both can be used in combination through hybrid methodologies. Striking a crucial balance between complex theories and practical applications, the text provides real-world examples of vibroacoustic simulation, such as fuselage simulation, interior-noise prediction for electric and combustion vehicles, train profiles, and more, to help elucidate the concepts described within. Vibroacoustic Simulation also features: A balance of complex theories with the nuts and bolts of real-world applications Detailed worked examples of junction equations Case studies from companies like Audi and Airbus that illustrate how the methods discussed have been applied in real-world projects A companion website that provides corresponding Python codes for all examples, allowing readers to work through the examples on their own Vibroacoustic Simulation is a useful reference for acoustic and mechanical engineers working in the automotive, aerospace, defense, or rail industries, as well as researchers and graduate students studying acoustics.

Victims of Fashion (Science in History)
by Helen Louise CowieAnimal products were used extensively in nineteenth-century Britain. A middle-class Victorian woman might wear a dress made of alpaca wool, drape herself in a sealskin jacket, brush her hair with a tortoiseshell comb, and sport feathers in her hat. She might entertain her friends by playing a piano with ivory keys or own a parrot or monkey as a living fashion accessory. In this innovative study, Helen Cowie examines the role of these animal-based commodities in Britain in the long nineteenth century and traces their rise and fall in popularity in response to changing tastes, availability, and ethical concerns. Focusing on six popular animal products – feathers, sealskin, ivory, alpaca wool, perfumes, and exotic pets – she considers how animal commodities were sourced and processed, how they were marketed and how they were consumed. She also assesses the ecological impact of nineteenth-century fashion.

Video Game Art Reader: Volume 4
by Tiffany FunkIn computing, overclocking refers to the common practice of increasing the clock rate of a computer to exceed that certified by the manufacturer. The concept is seductive but overclocking may destroy your motherboard or system memory, even irreparably corrupt the hard drive. Volume 4 of the Video Game Art Reader (VGAR) proposes overclocking as a metaphor for how games are produced and experienced today, and the temporal compressions and expansions of the many historical lineages that have shaped game art and culture. Contributors reflect on the many ways in which overclocking can be read as a means of oppression but also a strategy to raise awareness of how inequities have shaped video games. Contributions by Uche Anomnachi, Andrew Bailey, Chaz Evans, Tiffany Funk, D’An Knowles Ball, Alexandre Paquet, Chris Reeves, and Regina Siewald.
