Book Description
This is a manual of instruction for using the side scan sonar system in searching for underwater objects, to be used in conjunction with standard search manuals, such as the National Search and Rescue Manual (CG 308) and the manufacturers' instruction book. The general approach is twofold. The first is to present logical search methods for conducting a broad area search using a sensor such as a side scan sonar. The second is to present objective methods of interpreting side scan sonar images of objects on the seafloor by the operator. Side scan sonar records of four specific targets are presented in an interpretive portfolio to enable assessment of the sonar system's capability and to train unskilled operators. The four targets are: a small single engine aircraft, an automobile, a 40-ft. steel boat and a Coast Guard buoy. Two cases of opportunity involving sunken vessesl are presented. (Author).

Book Description
Applied Underwater Acoustics meets the needs of scientists and engineers working in underwater acoustics and graduate students solving problems in, and preparing theses on, topics in underwater acoustics. The book is structured to provide the basis for rapidly assimilating the essential underwater acoustic knowledge base for practical application to daily research and analysis. Each chapter of the book is self-supporting and focuses on a single topic and its relation to underwater acoustics. The chapters start with a brief description of the topic's physical background, necessary definitions, and a short description of the applications, along with a roadmap to the chapter. The subtopics covered within individual subchapters include most frequently used equations that describe the topic. Equations are not derived, rather, assumptions behind equations and limitations on the applications of each equation are emphasized. Figures, tables, and illustrations related to the sub-topic are presented in an easy-to-use manner, and examples on the use of the equations, including appropriate figures and tables are also included. - Provides a complete and up-to-date treatment of all major subjects of underwater acoustics - Presents chapters written by recognized experts in their individual field - Covers the fundamental knowledge scientists and engineers need to solve problems in underwater acoustics - Illuminates, in shorter sub-chapters, the modern applications of underwater acoustics that are described in worked examples - Demands no prior knowledge of underwater acoustics, and the physical principles and mathematics are designed to be readily understood by scientists, engineers, and graduate students of underwater acoustics - Includes a comprehensive list of literature references for each chapter

Book Description
Sidescan sonar is proving to be the preeminent technique for researchers and professionals seeking knowledge about the structure and behavior of the seafloor, but its data is often difficult to interpret due to the physics of acoustic remote sensing, and to the varied geological processes at play. This book covers the fundamentals of sidescan sonar, incorporates new understanding of marine structures, and explains how to interpret sidescan sonar imagery and bathymetry.

Book Description
Nearly ten years after the first edition of Water-Related Death Investigation: Practical Methods and Forensic Applications, water death cases continue to be improperly investigated. The pathologist’s report can determine the cause of death as a drowning, but the manner of death is the most challenging to prove. The report will not determine if a victim jumped into the water to commit suicide, fell into the water accidentally, or was pushed in as a homicidal act. Many drowning cases do not reflect injury to the body, so evidence collected at the scene plays a vital role. The importance of an on-scene body assessment cannot be overemphasized. Often, the body evidence begins to change rapidly upon recovery and may not be present during an autopsy. Written statements on the scene are an effective tool to use to determine the accuracy of information given to arriving officers. These statements need to be written by the witnesses themselves as well as the reporting person. The "Show Me" technique can also help reveal discrepancies in a person’s version of what occurred as well as aid in providing the most details to an incident as is humanly possible. This second edition includes updated information on the latest technology to assist water death investigators. Parabon Snapshot can help determine the faceless identity of skeletal remains and help locate potential suspects using the science of DNA. Drones can aid in locating missing persons as well as human remains, even months after death. Updated information is provided regarding fingerprints from submerged objects, and Carbon-14 can help determine the origin of a found corpse. Key Features: Thoroughly reviews the physiological aspects of drowning Reveals the investigative characteristics inherent to various scenes of water-related deaths Highlights certain "red flag" indicators that may point to foul play or scene staging Outlines autopsy protocols, trial preparation, and expert witness testimony Provides numerous case studies and numerous illustrations to further clarify key points presented in the text Coauthored by a Master Water Death Investigator and an experienced forensic pathologist, Water-Related Death Investigation: Practical Methods and Forensic Applications, Second Edition merges the essentials of evidence collection and field investigation with autopsy best practices and laboratory testing. It will continue to serve as a valuable resource for the various professionals involved in these cases.

Book Description
This book provides a systematic and comprehensive overview of cognitive intelligence and AI-enabled IoT ecosystem and machine learning, capable of recognizing the object pattern in complex and large data sets. A remarkable success has been experienced in the last decade by emulating the brain–computer interface. It presents the applied cognitive science methods and AI-enabled technologies that have played a vital role at the core of practical solutions for a wide scope of tasks between handheld apps and industrial process control, autonomous vehicles, IoT, intelligent learning environment, game theory, human computer interaction, environmental policies, life sciences, playing computer games, computational theory, and engineering development. The book contains contents highlighting artificial neural networks that are analogous to the networks of neurons that comprise the brain and have given computers the ability to distinguish an image of a cat from one of a coconut, to spot pedestrians with enough accuracy to direct a self-driving car, and to recognize and respond to the spoken word. The chapters in this book focus on audiences interested in artificial intelligence, machine learning, fuzzy, cognitive and neurofuzzy-inspired computational systems, their theories, mechanisms, and architecture, which underline human and animal behavior, and their application to conscious and intelligent systems. In the current version, it focuses on the successful implementation and step-by-step execution and explanation of practical applications of the domain. It also offers a wide range of inspiring and interesting cutting-edge contributions on applications of machine learning, artificial intelligence, and cognitive science such as healthcare products, AI-enabled IoT, gaming, medical, and engineering. Overall, this book provides valuable information on effective, cutting-edge techniques, and approaches for students, researchers, practitioners, and academics in the field of machine learning and cognitive science. Furthermore, the purpose of this book is to address the interests of a broad spectrum of practitioners, students, and researchers, who are interested in applying machine learning and cognitive science methods in their respective domains.
