36971.4.0门户网络编程接口
[信息传输、软件和信息技术服务业] [2014-04-08]
This report presents a specification for the Portals 4.0 network programming interface. Portals 4.0 is intended to allow scalable, high-performance network communication between nodes of a parallel computing system. Portals 4.0 is well suited to massively parallel processing and embedded systems. Portals 4.0 represents an adaption of the data movement layer developed for massively parallel processing platforms, such as the 4500-node Intel TeraFLOPS machine. Sandia's Cplant cluster project motivated the development of Version 3.0, which was later extended to Version 3.3 as part of the Cray Red Storm machine and XT line. Version 4.0 is targeted to the next generation more >of machines
employing advanced network interface architectures that support enhanced offload capabilities.

36972.2014年1-2月中国通信行业运行分析
[信息传输、软件和信息技术服务业] [2014-04-04]
电信业务总量和业务收入保持稳定增长。2014年2月份，电信业务总量保持稳步增长，全国电信业务总量完成1293.1亿元[按照2010年不变单价计算]，同比增长13.6%；电信主营业务收入906.1亿元，同比增长4.1%。1-12月，全国电信业务总量累计完成2704.3亿元，同比增长15.3%；电信主营业务收入累计完成1853.2亿元，同比增长6.6%，较上月增速略有回落，话音业务收入和网间结算收入下降是造成整体收入下滑的主要原因。

36976.深空光通信的双脉冲位置调制（DPPM）：性能和实用性分析
[信息传输、软件和信息技术服务业] [2014-04-03]
This paper evaluates the dual-pulse case and compares it with the conventional single-pulse case. Analytical expressions for symbol error rate and bit error rate are first derived and numerically evaluated, for the strong, negative-exponential turbulent atmosphere; and bandwidth efficiency and throughput are subsequently assessed. It is shown that, under a set of practical constraints including pulse width and pulse repetition frequency (PRF), dual-pulse PPM enables a better channel utilization and hence a higher throughput than it single-pulse counterpart. This result is new and different from the previous idealistic studies that showed multi-pulse PPM provided no essential information-theoretic gains than single-pulse PPM.

36977.SRVC：传感网络远程车辆分类（最终报告）
[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] [2014-04-03]
This report summarizes the results of a two-year research effort on sensornets for vehicle traffic classification. At the study outside, our main goals were to understanding the communications requirements for traffic monitoring systems (both short-range wireless inside a traffic sensornet, and wide-area to a central Traffic Management System), developing self-configuring traffic monitoring systems, and integrating prior work with these new results. The key outcomes of our research are to understand communications in a classification system, to carefully evaluate the effects of signature matching, and to further develop self-configuration. Finally, we tested our new approaches through a second major data collection exercise at USC.

Salient features of the Integrated Network include (a) a central system element that performs service management functions and user mission interfaces for service requests; (b) a set of common service execution equipment deployed at the all stations that provides return, forward, and radiometric data processing and delivery capabilities; (c) the network monitor and control operations for the entire integrated network are conducted remotely and centrally at a prime-shift site and rotating among three sites globally (a follow-the-sun approach); (d) the common network monitor and control software deployed at all three network elements that supports the follow-the-sun operations.

36979.非传统通信约束的网络系统的分布式控制：有损链接，功率和使用的限制，和诱导合作
[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] [2014-04-03]
As wireless sensing and control become increasingly applicable in elds ranging from real-time alarm systems and vehicle systems to aeronautical guidance and formation control, the need for establishing a theoretical foundation for what is known as networked systems R1 has grown likewise.Any effective effort to develop a theoretical foundation for this relatively new paradigm necessitates pooling together of tools from multiple seemingly disparate disciplines. Some salient aspects of this paradigm, and the challenging issues that arise in this context, which we have addressed in the research supported by this AFOSR grant, are as follows, where the generic term agents is used for entities that are responsible for decision making that leads to actions, be they sensors or controllers or even dynamical systems.

36980.量子通信系统
[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] [2014-04-03]
This project supported research activities for making quantum- enhanced communications and metrology practical. The strategy was to develop robust photonic quantum states and sensors serving as an archetype for loss- tolerant information acquisition beyond the standard quantum limit, as well as in finding practical sensing applications outside the laboratory for detecting objects in situations where power-limited illumination is critical.We have also been efficient in investigating fundamental issues of quantum metrology, establishing a general framework for understanding more complex scenarios, such as lossy parameter estimation, and joint measurements of multiple parameters. Investigations have fostered a novel approach which will inform our future researchers: the adoption of sensing networks in which quantum memories act as key devices.
