The Force Factor


Book Description

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.

Frequency Analysis of Vibration Energy Harvesting Systems


Book Description

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
