In this paper, a sports strategy decision support system, called SportsViz, for ball games is presented. Both the results of statistical analysis and player motions are visualized in an integrated way to facilitate easy decision making by this system. The player motions can be easily aggregated with our newly developed trajectory mining technique for deep consideration on the motions. This paper also describes how the system can be used for effective strategy analysis in American football.
Development of an underwater platform which travels and surveys across entire oceans for the research into the global change, ocean-trench earthquake, and biodiversity is addressed in Japan. The first prototype LCAUV powered by polymer electrolyte membrane fuel cell (PEFC) system named Urashima, which marked the world record of cruising distance of 317 km, had been developed since 1998. Key technology development including a fuel cell system for the second LCAUV started in 2007. A high efficiency PEFC developed by MHI for the LCAUV runs with 60 % of efficiency at an operation point. A function test for a new concept system, which consists of reduced auxiliary devices, using the PEFCs was made. The test results have positive outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
