Autonomous Underwater Vehicles by Nuno Cruz Pdf

Autonomous Underwater Vehicles (AUVs) are remarkable machines that revolutionized the process of gathering ocean data. Their major breakthroughs resulted from successful developments of complementary technologies to overcome the challenges associated with autonomous operation in harsh environments. Most of these advances aimed at reaching new application scenarios and decreasing the cost of ocean data collection, by reducing ship time and automating the process of data gathering with accurate geo location. With the present capabilities, some novel paradigms are already being employed to further exploit the on board intelligence, by making decisions on line based on real time interpretation of sensor data. This book collects a set of self contained chapters covering different aspects of AUV technology and applications in more detail than is commonly found in journal and conference papers. They are divided into three main sections, addressing innovative vehicle design, navigation and control techniques, and mission preparation and analysis. The progress conveyed in these chapters is inspiring, providing glimpses into what might be the future for vehicle technology and applications.

Space Fostering Latin American Societies by Annette Froehlich Pdf

This peer-reviewed book presents a comprehensive overview of the role space is playing in enabling Latin America to fulfill its developmental aspirations. Following on from the highly acclaimed Part 1, it explains how space and its applications can be used to support the development of the full range and diversity of Latin America societies, while being driven by Latin American goals. The Latin American space sector is currently undergoing a phase of rapid and dynamic expansion, with new actors entering the field and with space applications increasingly being used to support the continent’s social, economic, and political development. All across Latin America, attention is shifting to space as a fundamental part of the continental development agenda, and the creation of a Latin American space agency is evidence of this. Additionally, while in recent years, significant advances in economic and social development have lifted many of Latin America’s people out of poverty, there is still much that needs to be done to fulfill the basic needs of the population and to afford them the dignity they deserve. To this end, space is already being employed in diverse fields of human endeavor to serve Latin America’s goals for its future, but there is still a need for further incorporation of space systems and data. This book will appeal to researchers, professionals and students in fields such as space studies, international relations, governance, and social and rural development.

Fundamentals of Electric Propulsion by Dan M. Goebel,Ira Katz Pdf

Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.
