ic model based on results from vehicular traffic theory, that applies to vehicles and pedestrians in urban, suburban and highway cellular systems. The model helps quantify various design tradeoffs. We conclude that microcells are unnecessary in urban environments if the pedestrian penetration is sma无节奏 发表于 2025-3-28 21:22:15

Light Detectors,ective mass filters and superlattice avalanche photodiodes. Finally, new superlattice far infrared detectors using intersubband absorption and waveguide integrated with diode (using evanescent field absorption process) are reviewed. At last, the fabrication of such devices is explained.PAD416 发表于 2025-3-29 15:49:08
