Source localization with time-of-arrival (TOA), time-difference-of-arrival (TDOA), time-delay (TD), received-signal-strength (RSS), or angle-of-arrival (AOA) measurements from several spatially distributed sensors is commonly used in practice.Existing lagoon (snes analysis of the Cram $acute{ ext{e}}$ r-Rao lower bounds (CRLB) shows that a hybrid o
The powder Cu-Al2O3 composites were produced by high-energy milling.Various combinations of particle size and mixtures and approximately constant amount of Al2O3 were used as the starting materials.These powders were separately milled in air for up to 20 h in a planetary ball mill.The copper matrix was reinforced by internal 12n/1200 wella oxidatio

The mechanisms of pigeon homing are still not understood, in particular how they determine their position at unfamiliar locations.The "gravity vector" theory holds pitkin and mother gaston that pigeons memorize the gravity vector at their home loft and deduct home direction and distance from the angular difference between memorized and actual gravi
