Radio Frequency Micromachined Switches, Switching Networks, and Phase Shifters
Author: Shiban Kishen KoulPublisher: CRC Press
ISBN: 135102132X
Category : Science
Languages : en
Pages : 309
Book Description
Radio Frequency Micromachined Switches, Switching Networks, and Phase Shifters discusses radio frequency microelectromechanical systems (RF MEMS)-based control components and will be useful for researchers and R&D engineers. It offers an in-depth study, performance analysis, and extensive characterization on micromachined switches and phase shifters. The reader will learn about basic design methodology and techniques to carry out extensive measurements on MEMS switches and phase shifters which include electrical, mechanical, power handling, linearity, temperature stability, reliability, and radio frequency performance. Practical examples included in the book will help readers to build high performance systems/subsystems using micromachined circuits. Key Features Provides simple design methodology of MEMS switches and switching networks including SPST to SP16T switches Gives an in-depth performance study of micromachined phase shifters. Detailed study on reliability and power handling capability of RF MEMS switches and phase shifters presented Proposes reconfigurable micromachined phase shifters Verifies a variety of MEMS switches and phase shifters experimentally

Author: S J RussellPublisher: Woodhead Publishing
ISBN: 1845691997
Category : Technology & Engineering
Languages : en
Pages : 544
Book Description
Nonwovens are a unique class of textile material formed from fibres that are bonded together through various means to form a coherent structure. Given their rapid industrial development and diverse markets, understanding and developing nonwovens is becoming increasingly important. With its distinguished editor and array of international contributors, the Handbook of nonwovens, offers a comprehensive review of the latest advances in this area and how they can be applied to particular products. Initial chapters review the development of the industry and the different classes of nonwoven material. The book then discusses methods of manufacture such as dry-laid, wet-laid and polymer-laid web formation. Other techniques analysed include mechanical, thermal and chemical bonding as well as chemical and mechanical finishing systems. The book concludes by assessing the characterisation, testing and modelling of nonwoven materials. Handbook of nonwovens is a valuable reference for those involved in the manufacturing and use of nonwoven products in such areas as; transport, medicine, hygiene and various branches of engineering. Provides a comprehensive review of the latest advances in this important area Written by leading experts in the field Discusses different methods of manufacture, bonding and finishing

Author: The Problem with Survey Research
Author: George BeamPublisher: Routledge
ISBN: 1351476254
Category : Social Science
Languages : en
Pages : 243
Book Description
The Problem with Survey Research makes a case against survey research as a primary source of reliable information. George Beam argues that all survey research instruments, all types of asking-including polls, face-to-face interviews, and focus groups-produce unreliable and potentially inaccurate results. Because those who rely on survey research only see answers to questions, it is impossible for them, or anyone else, to evaluate the results. They cannot know if the answers correspond to respondents' actual behaviors (objective phenomena) or to their true beliefs and opinions (subjective phenomena). Reliable information can only be acquired by observation, experimentation, multiple sources of data, formal model building and testing, document analysis, and comparison. In fifteen chapters divided into six parts-Ubiquity of Survey Research, The Problem, Asking Instruments, Asking Settings, Askers, and Proper Methods and Research Designs-The Problem with Survey Research demonstrates how asking instruments, settings in which asking and answering take place, and survey researchers themselves skew results and thereby make answers unreliable. The last two chapters and appendices examine observation, other methods of data collection and research designs that may produce accurate or correct information, and shows how reliance on survey research can be overcome, and must be.
