Geolocation is a process that utilizes sensors to pick up enemy emissions and locate electronic warfare (EW) targets. It is of particular interest among EW professionals because it allows them to use the enemy's own emissions to help set GPS coordinates and accurately pinpoint a target for attack. This is a newly revised and greatly expanded edition of a classic Artech House book. It offers practical guidance in electronic warfare target location. It features a wealth of additional material, including important new chapters on time delay estimation and direction finding techniques. It provides practitioners with critical information on a variety of geolocation algorithms and techniques.
Drawing on the authors' more than six years of R&D in location-based information systems (LBIS) as well as their participation in defining the Java ME Location API 2.0, Location-Based Information Systems: Developing Real-Time Tracking Applications provides information and examples for creating real-time LBIS based on GPS-enabled cellular phones. Each chapter presents a general real-time tracking system example that can be easily adapted to target any application domain and that can incorporate other sensor data to make the system "participatory sensing" or "human-centric sensing."
The book covers all of the components needed to develop an LBIS. It discusses cellular phone programming using the Java ME platform, positioning technologies, databases and spatial databases, communications, client- and server-side data processing, and real-time data visualization via Google Maps and Google Earth. Using freely available software, the authors include many code examples and detailed instructions for building your own system and setting up your entire development environment.
Although LBIS applications are still in the beginning stages, they have the potential to transform our daily lives, from warning us about possible health problems to monitoring pollution levels around us. Exploring this novel technology, Location-Based Information Systems describes the technical components needed to create location-based services with an emphasis on nonproprietary, freely available solutions that work across different technologies and platforms.
Shoulder dislocation is a frequent traumatic event. Unfortunately it has chronic consequences, especially shoulder instability. Conventional medicine proposes surgery for stabilization. Conservative treatment can be applied with success. This is the topic of my booklet.
