5573.纳米认知推理超大规模集成电路(VLSI)计算机结构探索
[计算机、通信和其他电子设备制造业] [2013-10-24]
The objectives of this work were to design, develop, and evaluate support for the design of low-power hardware computer architectures at the Very Large Scale Integration (VLSI) level. The objectives were realized by achieving complete design flow integration with commercial and open-source Electronic Design Automation tools. The design flow takes as inputs a high-level system-level architecture description, along with area, critical path delay, and power dissipation constraints. Based on the System on Chip architecture description and design constraints, the tools automatically generate synthesizable Hardware Descriptive Language (HDL) models, embedded memories, and custom components to implement the specified VLSI architecture. Simulation results showed significant improvement over previous approaches with respect to power dissipation and leakage reduction.

5575.占领信息制高点:中国计算机网络操作和网络安全间谍能力
[计算机、通信和其他电子设备制造业] [2013-10-24]
The present study is intended to be a detailed follow up and expansion upon a 2009 assessment prepared for the U.S.-China Economic and Security Review Commission of Chinas evolving computer network operations capabilities and network intrusion incidents attributed to China. Concern in the United States over alleged Chinese penetrations of both commercial and government networks has only intensified in the past two years as successive incidents have come to light in the media and more organizations voluntarily come forward. The Commission requested a study that both reviewed developments since the 2009 study was completed and examined new issues related to cybersecurity, China, and potential risks to U.S. interests.

5576.计算机辅助的多数据融合体育建模
[信息传输、软件和信息技术服务业] [2013-10-24]
Recent research efforts strive to address the growing need for dismount surveillance, dismount tracking and characterization. Current work in this area utilizes hyperspectral and multispectral imaging systems to exploit spectral properties in order to detect areas of exposed skin and clothing characteristics. Because of the large bandwidth and high resolution, hyperspectral imaging systems pose great ability to characterize and detect dismounts. A multi-data dismount modeling system where the development and manipulation of dismount models is a necessity. This thesis demonstrates a computer aided multi-data fused dismount model, which facilitates studies of dismount detection, characterization and identification. The system is created by fusing: pixel mapping, signature attachment, and pixel mixing algorithms. The developed multi-data dismount model produces simulated hyperspectral images that closely represent an image collected by a hyperspectral imager. The dismount model can be modified to fit the researcher's needs. The multi-data model structure allows the employment of a database of signatures acquired from several sources. The model is flexible enough to allow further exploitation, enhancement and manipulation. The multi-data dismount model developed in this effort fulfills the need for a dismount modeling tool in a hyperspectral imaging environment.

5578.计算机辅助容器协助处理人体工学起重机操作
[信息传输、软件和信息技术服务业] [2013-10-24]
Efficient container handling system at the ports leads to reduced ship waiting time, increased productivity, cost reduction, and lowered harmful emissions to the environment. Terminal operators use the free flow of information from the ships to streamline containers that move from the vessel through the gantry cranes or quayside container cranes to the truck or the rail, and finally transport out of the terminal gate. The loading and unloading of containers from a starting position to a destination is conducted visually by experienced crane operators from inside the crane cab situated high above the ground for several hours daily. To improve crane safety and port productivity, we proposed an assistive user interface that integrates visual and haptic (force) feedback to assist the crane operator during container handling process. In this phase, the work focuses on the design and construction of a scaled testbed with visual and force feedback system to provide motion guidance. The visual feedback is provided by a camera and the force feedback is provided through a force-feedback joystick, which are integrated in MATLAB/Simulink. The motion guidance is provided as a force cue to alert the operator of surrounding objects and avoid possible collision. A preliminary experiment was conducted on the testbed to investigate the performance of the integrated system and the feasibility of the proposed technology. Initial results indicate the potential of the system in preventing collision and improved ergonomics; however, further user experiment will be needed.

5579.涵盖计算机和互联网的ACS内容测试评估报告,2010
[信息传输、软件和信息技术服务业] [2013-10-24]
In late August through mid-December 2010, the Census Bureau conducted a field test of new and revised content in the 2010 American Community Survey (ACS) Content Test. The results of that testing will determine the content to be incorporated into production ACS starting in 2013. Computer ownership and Internet subscription questions need to be added into the American Community Survey due to legislative changes. The Broadband Data Improvement Act requires that the Secretary of Commerce, in consultation with the Federal Communications Commission, expand the ACS to elicit information from residential households to determine whether they own or use computers at their address, whether they subscribe to an Internet service and, if so, whether they subscribe to dial-up or broadband Internet service at that address. The goal of this project is to evaluate the two versions of computer ownership and Internet subscription questions in the 2010 ACS Content Test to help determine which one will ultimately go into ACS production starting in 2013.

5580.虚拟机监控程序立足于个人电脑的安全:研究社区议程
[计算机、通信和其他电子设备制造业] [2013-10-24]
The purpose of this paper is to propose the creation of a security- enhancing hypervisor for PCs as a collaborative agenda for the research community. This agenda is not necessarily about answering fundamentally new research questions. Rather, it is a call to action about a rare chance for the community to have substantial impact. If researchers demonstrate compelling near-term benefits from a modest security layer, then OS vendors may adopt such a layer as a way to increase security without costly reengineering. The introduction of this secure foothold into the consumer software stack could then yield significant long-term benefits by providing a much better avenue for deploying security solutions. This agenda consists of two parts: (1) exploring how hypervisors can address end-user security issues and (2) exploring how to architect a small, secure hypervisor that provides several of these facilities. We believe that there are interesting and worthwhile challenges in both parts. The rest of this paper is organized as follows. We begin by explaining why hypervisors provide a highly attractive insertion point for security (Section 2) and summarizing work in this area (Section 3). We then discuss security facilities that a hypervisor can provide in Section 4, with a focus on trusted paths to online services. We conclude by discussing challenges associated with our proposal in Section 5.
