Large Unmanned Aerial Vehicle (UAV) clusters, containing hundreds of UAVs, have widely been used in the modern world. Therein, mission planning is core large UAV cluster collaborative systems. In this paper, we propose a method by introducing Simple Attention Model (SAM) into Dynamic Information Reinforcement Learning (DIRL), named DIRL-SAM. To reduce computational complexity original attention...

these are notes from introductory survey lectures given at the institute for studies in theoretical physics and mathematics (ipm), teheran, in 2008 and 2010. we present the definition and the fundamental properties of fomin-zelevinsky’s cluster algebras. then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generators of ...

one of the most popular management tools, the mission statement, also is subject to widespread criticism. in order to improve our understanding of the mission statement’s strategic value and to provide actionable and scientific recommendations for mission statement formulation have been tried by reviewing different strategic management texts, is represented a comprehensive model for formulation...

Due to application of WSN in mission critical areas, secured message communication is very important. We have attempted to present a methodology that ensures secured communication among nodes in a hierarchical Cluster Based WSN. Our scheme works when member sensor nodes move from one Cluster Head (CH) to another. The proposed scheme is based on Key Redistribution during node mobility and develo...

In this work, we propose a low-power consumption hierarchical topology control algorithm for wireless sensor network, which is called LDH. As a control topology algorithm with multi-levels, it contains two phases: network establishment and network maintenance. The phase of network establishment contains three missions: electing of cluster head, identifying cluster head and nodes, as well as opt...

Several NASA and DoD missions are envisioned that will utilize distributed, autonomous clusters of spacecraft. The Air Force Research Laboratory initiated the TechSat 21 mission to demonstrate the key enabling technologies of formation flying and distributed radar. Princeton Satellite Systems developed the Formation Flying Module (FFM) for TechSat 21 to provide autonomous reconfiguration, forma...
