  • 32721.使用传感器鱼通过鱼堰和涡轮福斯特大坝俄勒冈州1号机组确定鱼道条件表征

    [计算机、通信和其他电子设备制造业] [2014-05-13]

    Fish passage conditions through a Kaplan turbine and spillway fish weir at Foster Dam, located on the South Santiam River in Linn County, Oregon, were evaluated by Pacific Northwest National Laboratory for the U.S. Army Corps of Engineers, Portland District, using Sensor Fish devices. The objective of the study was to describe and compare passage exposure conditions, identifying potential fish injury regions encountered during passage via specific routes. The investigation was performed in May 2012, concurrent with HI-Z balloon-tag studies by Normandeau Associates, Inc. Sensor Fish data were analyzed to characterize the passage exposure conditions through the spillway fish weir and turbine Unit 1 at Foster Dam at two forebay pool elevations (616 and 634 ft mean sea level (MSL)) and to estimate data relationships with live fish injury and mortality estimates. For the spillway fish weir evaluation, Sensor Fish and live fish were deployed through injection system piping mounted on the weir. The bottom of the injection pipe was at an elevation of approximately 614 ft during testing at the 616-ft MSL (low) forebay elevation and at 632 ft during the 634-ft MSL (high) forebay level tests. Two systems were useda 4-in. pipe for juvenile fish releases and an 8-in. pipe for adult releases at each elevation.

  • 32722.为国际反人口贩运系统开发的实物保护系统试验台

    [计算机、通信和其他电子设备制造业] [2014-05-13]

    Physical protection systems have a widespread impact across the nuclear industry in securing facilities and making security systems more effective and robust. They play an integral role in nuclear safeguards, arms control, and trafficking of illicit goods (e.g., nuclear materials) across international borders. As an example, many challenges must be overcome in design and deployment of foreign border security systems such as lack of infrastructure, extreme environmental conditions, limited knowledge of terrain, insider threats, cultural resistance, distance/time for response, lack of equipment training, and ingenuity in adversary response/bypass. Successful security systems rely on an integrated system composed of multiple subsystems. A physical protection systems test bed has been constructed at Oak Ridge National Laboratory whose mission is to test systems in varied non-ideal terrain and environmental conditions for prolonged periods of time for specific deployment scenarios. This includes a complete assessment of a systems vulnerability of defeat. This test bed is composed of many unique sensors and subsystems, including wireless unattended ground sensors, a buried fiber-optic acoustic sensor, a lossy coaxial distributed sensor, wireless links, pan-tilt-zoom cameras, mobile power generation systems, unmanned aerial vehicles, and fiber-optic-fence intrusion detection systems.

  • 32723.用于轻度创伤性脑损伤的光子生物传感器的分析与设计

    [计算机、通信和其他电子设备制造业] [2014-05-13]

    This report describes a molecular biosensor that includes a lipid vesicle and housing wherein the vesicle is contained on orwithin the housing and where the housing has a portion capable of transmitting a force generated external to the housing to the vesicle. The biosensor detects the presence or absence of an event force, such as a blast or blunt force sufficient to produce a medical complication, such as traumatic brain injury.

  • 32724.用于应用测试的光纤传感器分析

    [计算机、通信和其他电子设备制造业] [2014-05-13]

    Fiber optic sensing is a rapidly developing emergent technology in which a number of systems are currently in development. Potential applications at the U.S. Army Research Laboratory (ARL) include ballistic shock sensors, loading rate strain sensors, acoustic emission crack detectors, fiber laser vibrometers, velocity sensors for structural vibration, and others. This report provides a comprehensive overview of the fiber sensor technology, interferometric implementations, and the range of sensor system platforms that can be applied to improve ARL s ability to support its test requirements.

  • 32725.物联网相关研究问题的讨论与分析

    [信息传输、软件和信息技术服务业,计算机、通信和其他电子设备制造业] [2014-05-12]

    1999年,在美国召开的移动计算和网络国际会议上首次提出了“物联网”(IOT,The Internet of Things)的概念。虽然近年来物联网技术及应用取得迅猛的发展,但是对物联网一直都没有一个权威的定义。目前被普遍认可的一种定义是:通过射频识别(RFID,Radio Frequency IDentification)装置、红外感应器、全球定位系统、激光扫描器等信息传感设备,按约定的协议,把任何物品与互联网相连接,进行信息交换和通信,以实现智能化识别、定位、跟踪、监控和管理的一种网络。这个定义有两层意思:一是物联网的核心和基础仍然是互联网,是在互联网基础之上延伸和扩展的一种网络;二是其用户端延伸和扩展到了任何物品与物品之间,进行信息交换和通信。
