Book excerpt: This study focused on the level of force used by police officers relative to the amount of suspect resistance, referred to as the force factor. Data were obtained from police departments in Miami, Florida, and Eugene, Oregon. In the Miami data set, the level of suspect resistance was assessed according to four categories: no resistance, passive resistance, active resistance, and assault of police officer. The suspect being Hispanic was the strongest factor in the force factor model. Female suspects received less force relative to level of resistance than male suspects, while black suspects received the most force relative to level of resistance. The relationship between the force factor and the suspect being under the influence of alcohol or drugs during the encounter with the police was statistically significant. Female police officers used significantly less force for a given level of resistance than male police officers. Police officer injury was more likely to occur when less force was used relative to suspect resistance. In the Oregon data set, the level of suspect resistance was also assessed according to four categories: no resistance, slight resistance, moderate or high resistance, and violent or explosive resistance. The suspect's mental status at the time of the incident was the strongest factor in the force factor model. Suspects using minimal effort had the most force used against them relative to level of resistance. Violent incidents had the lowest levels of force relative to level of resistance, suspects with above average fitness received lower levels of force relative to level of resistance than suspects with average to poor physical fitness, and female suspects had less force used against them relative to level of resistance than male suspects. Further development of the force factor model is recommended.

Available in PDF, EPUB and Kindle. Book excerpt: Frequency Analysis of Vibration Energy Harvesting Systems aims to present unique frequency response methods for analyzing and improving vibration energy harvesting systems. Vibration energy is usually converted into heat energy, which is transferred to and wasted in the environment. If this vibration energy can be converted into useful electric energy, both the performance and energy efficiency of machines, vehicles, and structures will be improved, and new opportunities will open up for powering electronic devices. To make use of ambient vibration energy, an effective analysis and design method is established and developed in this book. The book covers a wide range of frequency response analysis methods and includes details of a variety of real-life applications. MATLAB programming is introduced in the first two chapters and used in selected methods throughout the book. Using the methods studied, readers will learn how to analyze and optimize the efficiency of vibration energy systems. This book will be ideal for postgraduate students and researchers in mechanical and energy engineering. - Covers a variety of frequency response analysis methods, including Fourier and Laplace transform, transfer function, integration and state space for piezoelectric and electromagnetic vibration energy harvesting analysis - Provides coverage of new and traditional methods of analyzing and optimizing the power and efficiency of vibration energy harvesting systems, with MATLAB exercises provided throughout - Demonstrates a wide range of real-life applications, such as ocean wave energy conversion, vehicle suspension vibration energy harvesting, and more

Download or read book Ultrasonic Transducer Materials written by O. E. Mattiat and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years remarkable progress has been made in the development of materials for ultrasonic transducers. There is a continuing trend towards increasingly higher frequency ranges for the application of ultrasonic trans ducers in modern technology. The progress in this area has been especially rapid and articles and papers on the subject are scattered over numerous technical and scientific journals in this country and abroad. Although good books have appeared on ultrasonics in general and ultrasonic transducers in particular in which, for obvious reasons, materials play an important part, no comprehensive treatise is available that represents the state-of-the-art on modern ultrasonic transducer materials. This book intends to fill a need for a thorough review of the subject. Not all materials are covered of which, theoretically, ultrasonic trans ducers could be made but those that are or may be of technical impor tance and which have inherent electro acoustic transducer properties, i.e., materials that are either magnetostrictive, electrostrictive, or piezoelectric. The book has been devided into three parts which somewhat reflect the historic development of ultrasonic transducer materials for important tech nical application. Chapter 1 deals with magnetostrictive materials, magnetostrictive met als and their alloys, and magnetostrictive ferrites (polycrystalline ceramics). The metals are useful especially in cases where ruggednes of the transducers are of overriding importance and in the lower ultrasonic frequency range.

Download or read book Risk Assessment and Management of Repetitive Movements and Exertions of Upper Limbs written by Daniela Colombini and published by Elsevier. This book was released on 2002-04-23 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: In industrialised countries, musculo-skeletrical disorders of the upper limbs represent one of the commonest work-related diseases. All working activities habitually requiring repetitive upper limb movements and exertions represent a potential risk for these disorders under certain conditions. This practical manual provides a clear and detailed solution to the problem of assessing and consequently managing these risks in conformity with European Union legislation covering the safety and protection of workers' health. The book contains many tables, diagrams and schedules, enhancing its practical value. The methods it proposes for analyzing and designing or redesigning jobs and tasks do not require sophisticated equipment and are largely based on situations encountered in large manufacturing factories. Since risk analysis also concerns how jobs and tasks are organized, many concepts and terms are defined that prevention experts can share with those responsible for planning and organizing manufacturing activities on the shop floor.

Download or read book High-Power Piezoelectrics and Loss Mechanisms written by Kenji Uchino and published by CRC Press. This book was released on 2020-09-09 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: As one of the pioneers of "Piezoelectric Actuators", I have contributed to the commercialization of various products for over 45 years, including million-selling devices, micro-ultrasonic motors for smart-phone camera modules by Samsung Electromechanics, piezoelectric transformers for backlight inverters by Apple laptops, multilayer PZT actuators for diesel injection valves by Denso Corporation, and piezoelectric energy harvesting modules for Programable Air-Burst Munition by the US Army. During the development period for "piezoelectric actuators and transformers," I found that the bottleneck for device miniaturization was heat generation under a high-power drive condition. Thus, in parallel to the piezo-actuator developments, I have been developing various high-power density piezo-ceramic materials with the loss mechanism clarification. Hence, I considered that it was time to organize a textbook based on the previous studies, including my materials development philosophy to stimulate younger generations to reach to the energy density of up to 100 W/cm3 in the future. Increasing efficiency and saving energy and space (compactness) are one of the important approaches in this 21st-century "sustainable society." High-Power Piezoelectrics and Loss Mechanisims introduces the theoretical background of piezoelectrics, electromechanical phenomenology, loss mechanisms, practical materials, device designs, drive and characterization techniques, and typical applications, and looks forward to the future perspectives in this field. This book is NOT an overall review of this area, but it focuses on important and basic ideas under my development philosophy to understand how to design and develop high-power piezoelectric materials and devices. This textbook is designed for self-learning by the reader aided by the availability of: • Chapter Essentials – Summary for quick memory recovery • Check Points – Answers are provided in the Appendix • Example Problems – To enhance the reader’s understanding with full, detailed solutions • Chapter Problems – For the final exam or further consideration

Download or read book MicroMechatronics, Second Edition written by Kenji Uchino and published by CRC Press. This book was released on 2019-07-19 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: After Uchino’s introduction of a new terminology, ‘Micromechatronics’ in 1979 for describing the application area of ‘piezoelectric actuators’, the rapid advances in semiconductor chip technology have led to a new terminology MEMS (micro-electro-mechanical-system) or even NEMS (nano-electro-mechanicalsystem) to describe mainly thin film sensor/actuator devices, a narrower area of micromechatronics coverage. New technologies, product developments and commercialization are providing the necessity of this major revision. In particular, the progresses in high power transducers, loss mechanisms in smart materials, energy harvesting and computer simulations are significant. New technologies, product developments and commercialization are providing the updating requirement for the book contents, in parallel to the deletion of old contents. Various educational/instructional example problems have been accumulated, which were integrated in the new edition in order to facilitate the self-learning for the students, and the quiz/problem creation for the instructors. Heavily revised topics from the previous edition include: high power transducers, loss mechanisms in smart materials, energy harvesting and computer simulations New technologies, product developments and commercialization helped shape the updated contents of this book where all chapters have been updated and revised. This textbook is intended for graduate students and industrial engineers studying or working in the fields of electronic materials, control system engineering, optical communications, precision machinery, and robotics. The text is designed primarily for a graduate course with the equivalent of thirty 75-minute lectures; however, it is also suitable for self-study by individuals wishing to extend their knowledge in the field.
