feldspar grains, as a significant provenance indicator, of two terrigenous formations from central iran, the upper red formation, and moghan area, zivah formation, are used for provenance determination and the study of transportation and depositional history. the upper red formation (urf) is volumetrically the most important siliciclastic unit of the central iran and zivah formation (zf) repres...

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...
