1. Omran Ahmadi (Institute for Research in Fundamental Sciences (IPM), Iran) Sets with many pairs of orthogonal vectors over finite fields Abstract: Let n be a positive integer and B be a non-degenerate symmetric bilinear form on Fq, where q is an odd prime power and Fq is the finite field with q elements. We determine the largest possible cardinality of a subset S ⊂ Fq such that |{B(x, y) |x, ...

drought causes significant reductions in crop productivity in many parts of the world, including iran. identifying genotypes tolerant to drought stress is therefore one of the foremost goals of crop breeding programs. this study investigated the effect of terminal drought stress on yield and yield components of new winter rapeseed lines, and identified new winter rapeseed lines tolerant to term...

Extended Abstract Many applications of distributed autonomous robotic systems can benefit from, or even may require, the team of robots staying within communication connectivity. For example, consider the problem of multirobot surveillance (Ahmadi & Stone 2006), in which a team of robots must collaboratively patrol a given area. If any two robots can directly communicate at all times, the robot...
