44102.从STS-134和空间操作模拟中心的猎户座视觉导航传感器的性能比较
[计算机、通信和其他电子设备制造业] [2013-12-21]
The Orion Multi-Purpose Crew Vehicle is a new spacecraft being designed by NASA and Lockheed Martin for future crewed exploration missions. The Vision Navigation Sensor is a Flash LIDAR that will be the primary relative navigation sensor for this vehicle. To obtain a better understanding of this sensor's performance, the Orion relative navigation team has performed both flight tests and ground tests. This paper summarizes and compares the performance results from the STS-134 flight test, called the Sensor Test for Orion RelNav Risk Mitigation (STORRM) Development Test Objective, and the ground tests at the Space Operations Simulation Center.

44103.全球晶体振荡器市场报告（2014-2018年）
[计算机、通信和其他电子设备制造业,电气机械和器材制造业] [2013-12-21]
Crystal oscillators are electronic circuits that generate electrical signals with precise frequencies. To generate these electrical signals, they make use of a vibrating crystal made of piezoelectric material. The frequency generated is used to keep constant track of time and provide a timely clock signal for electronic integrated circuits. This frequency is also used to stabilize frequencies for radio transmitters and receivers. Crystal oscillators find their application in a large number of devices such as cell phones (smartphones and feature phones), tablet computers, wristwatches,clocks, FM radios, medical electronic equipment, automotive systems (tyre pressure monitoring systems and anti-braking systems), and personal computers.

44107.IEEE802.11DCF的一种优化退避算法
[计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2013-12-20]
为了提升无线网络的整体性能,通过IEEE 802.11MAC(媒体访问控制)层DCF(分布式协调功能)在基本工作模式下所使用的二进制退避算法和CW(竞争窗口)的大小对网络整体性能的影响进行了分析。采用了增大初始CW、取消信道从忙碌变为空闲后继续退避需要等待的DIFS(分布式帧间间隔)和设置一个中间值作为阀值使得节点发送失败或成功后采用不同的退避算法进行退避这3种措施来优化DCF方式下的退避机制。经OPNET仿真验证,改进算法能够有效地降低网络接入时延并能提高网络吞吐量。
