We present a novel approach for locally guiding a group of agents amidst static and dynamic obstacles using the concept of prioritized formations. Our approach plans over a joint formation-velocity space employing a Bayesian scheme for evaluating the priority values of formations and a collision avoidance algorithm that accounts for the anisotropic nature of rotating formations. It guarantees c...

Zhu, Guangwei Ph.D., Purdue University, May 2013. Quantitative Analysis of MultiAgent Formations: Theory and Applications. Major Professor: Jianghai Hu. In this thesis, formations of multi-agent systems, including multi-vehicle systems and sensor networks, are studied from a quantitative perspective. First, matrix and scalar valued quantities related to multi-agent system formations are propose...

We describe the two classes of languages recognized by the groups D4 and Q8, respectively. Then we show that the formations of languages generated by these two classes are the same. We also prove that these two formations are closed under inverses of morphisms, which yields a language theoretic proof of the fact that the group formations generated by D4 and Q8, respectively, are two equal varie...

BACKGROUND One of the most prevalent problems in hemodialysis patients is sleep disturbance. Poor sleep quality has unpleasant bio-psycho-social outcomes. The positive effects of implementing the continuous care model (CCM) were verified with different variables, including sleep quality. This study was done with different populations, using two groups. OBJECTIVES This study aims to identify t...

This paper is concerned with the maintenance of rigid formations of mobile autonomous agents. A key element in all future multi-agent systems will be the role of sensor and communication networks as an integral part of coordination. Network topologies are critically important for autonomous systems involving mobile underwater, ground and air vehicles and for sensor networks. This paper focuses ...
