Robot formations imply the establishment and the maintenance of a predetermined geometric shape by a group of robots. In this work, we achieve formations using robots with proximity sensors of short detection range and no inter-robot communication equipment. This fact turns the synthesis problem into a hard one compared to those cases where the robot has information about the absolute location ...

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...

In this paper, we analyze tactical conflicts between attacking formations and blocking formations in the phase of reception attack in volleyball, using a zerosum game model. In this model, we categorize the attacking formations into 9 patterns which consist of 3 moving patterns of forward players and 3 positions (right, center and left) from which the ball can be spiked. We also categorize the ...

Most often, autonomous robots maintain group formations by using global information such as the position of the group leader or even the position of all robots inside the formation. Alternative approaches to autonomous robot formations have considered local information, which is more realistic but presents some drawbacks such as troop deformation. In this paper we perform a step forward in loca...

In previous work, we demonstrated an algorithm that treats a group of robots as a 1-dimensional cellular automaton, which is able to establish formations defined by a single mathematical function. We now extend the algorithm to establish grid formations.

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...

The present study was carried out to determine the possible origins of sediments entering Taleghan Dam in northern part of Iran, in order to avoid further sedimentation and helping in extension of the useful life of the proposed dam. This was performed by XRD analysis. To do so, first of all, sediment sampling points were positioned along the Taleghan River. The collected samples, after coding,...

ADSlraCI: 1rns paper aoaresses roDUSIcomroi OJ mumpre mobile robots moving in desired formations. A rigorous control technique for such an agent-based robotic system may encounter problems of singularity, parameter sensitivity and inter-robot collision. Our proposed approach focuses on the enhancement of robustness as well as collision-free establishment of formations even in the case of singul...

ABSTRACT Karst environments preserve some of the best archives past climate, vegetation, hydrology, anthropogenic impact, and landscape evolution providing that a reliable chronology can be established. Here we present an example system Plitvice Lakes (Dinaric karst, Croatia), which is characterized by intensive tufa lake sediment formations. The radiocarbon dating method, combined with other m...
