Dynamic Resonance Effects in the Statistical Distributions of Asteroids and Comets

Some principles in the distribution of Centaurs and the "Scattered Disk" objects, as well as the Kuiper belt objects for its semi-major axes, eccentricities and inclinations of the orbits have been investigated. It has been established, that more than a half from them move on the resonant orbits and that is what has been predicted earlier. The divergence of the maximum in the observable distribution of the objects of the Kuiper belt for the semi-major axes with an exact orbital resonance has been interpreted.Comment: 7 pages, 5 figures, 1 table.

Conformal GaP layers on Si wire arrays for solar energy applications

We report conformal, epitaxial growth of GaP layers on arrays of Si microwires. Silicon wires grown using chlorosilane chemical vapor deposition were coated with GaP grown by metal-organic chemical vapor deposition. The crystalline quality of conformal, epitaxial GaP/Si wire arrays was assessed by transmission electron microscopy and x-ray diffraction. Hall measurements and photoluminescence show p- and n-type doping with high electron mobility and bright optical emission. GaP pn homojunction diodes on planar reference samples show photovoltaic response with an open circuit voltage of 660 mV

Modelling and Simulation of Tactical Team Behaviour

Realistic military simulations are needed for analysis, planning, and training. Intelligentagent technology is a valuable software concept with the potential of being widely used inmilitary simulation applications. They provide a powerful abstraction mechanism required fordesigning simulations of complex and dynamic battlefields. Their ability to model the tacticaldecision-making behaviour of simulated battlefield entities gives them an edge over othertechniques. During battlefield simulation, these entities generally represent individualisticbehaviour, taking operational order from higher control and executing relevant plans. However,since a complex battlefield scenario typically involves thousands of entities, their coordinatedteam behaviour should also be considered to make the simulation more realistic. This paperdemonstrates the use of intelligent agent-based team behaviour modelling concepts in simulatingthe armoured tanks in a tactical masking scenario
