The fusion of multiple behavior commands and sensor data into intelligent and cohesive robotic movement has been the focus of robot research for many years. Sequencing low level behaviors to create high level intelligence has also been researched extensively. Cohesive robotic movement is also dependent on other factors, such as environment, user intent, and(More)
Many envisioned applications of mobile robotic systems require the robot to navigate in complex urban environments. This need is particularly critical if the robot is to perform as part of a synergistic team with human forces in military operations. Historically, the development of autonomous navigation for mobile robots has targeted either outdoor or(More)
Under various collaborative efforts with other government labs, private industry, and academia, SPAWAR Systems Center Pacific (SSC Pacific) is developing and testing advanced autonomous behaviors for navigation, mapping, and exploration in various indoor and outdoor settings. As part of the Urban Environment Exploration project, SSC Pacific is maturing(More)
With the increase in web based enterprise services, there is an increasing trend among business enterprises to migrate to web services platform. Web services paradigm poses a number of new security challenges, which can only be realized by developing effective access control models. The fact that the enterprises allow access to the resources through web(More)
Cardiovascular disease is the world's leading killer, accounting for 16.7 million or 29.2 per cent of total global deaths every year. The World Health Organization estimates that 60 per cent of the world's cardiac patients will be Indian by 2010. The reported prevalence of coronary heart disease (CHD) in adult surveys has risen 4-fold over the last 40 years(More)
