  • 3941.DESIRE项目中的机器人硬件设计

    [电气机械和器材制造业] [2014-04-08]

    The difficulties one faces when developing a service robot increase exponentially with the number of different modules and functions to be included. In the DESIRE project a new service robot was to be built as a means for advancing and demonstrating the convergence of service robotics technologies. It also had to meet the often contradicting requirements and demands of all thirteen partners and their heterogeneous software modules and functions which they committed to this project. In this article we will discuss the development process of the hardware of the DESIRE technology platform. Starting with the listing and description of the different components and requirements we will describe the development process of the platform's frame and internal structure as well as the design of the outer cover. We expect this chapter to be used as inspiration and guideline for other engineers in upcoming projects with similar settings concerning system complexity and team composition. We are confident that the experience of the robot development process gathered within a large joint research project will help others to identify potential pitfalls and challenges for a robot's hardware design beforehand and thus reduce the effort, time and resources needed for future service robot development.

  • 3942.联邦信息系统的概念供应链风险管理实践

    [信息传输、软件和信息技术服务业] [2014-04-08]

    Federal agency information systems are increasingly at risk of both intentional and unintentional supply chain compromise due to the growing sophistication of ICT and the growing speed and scale of a complex, distributed global supply chain. Federal departments and agencies currently have neither a consistent nor comprehensive way of understanding the often opaque processes and practices used to create and deliver the hardware and software products and services that it procures. This lack of understanding, visibility, traceability, and control increases the challenges associated with managing the risk of exploitation through a variety of means including counterfeit materials, malicious software, or untrustworthy products. Overall, it makes it increasingly difficult for federal departments and agencies to understand their exposure and manage the associated supply chain risks. Currently, federal departments and agencies and many private sector integrators and suppliers use varied and nonstandard practices, exacerbating the challenge.

  • 3943.多移动机器人的硬件

    [电气机械和器材制造业] [2014-04-08]

    In this chapter, three types of Gorilla Robots developed as the Multi-Locomotion Robot were described. Gorilla Robot was designed to be able to perform biped locomotion, quadruped locomotion, and brachiation etc. The hardware configuration of each Gorilla Robot and control system architecture were presented. In the subsequent chapters, Gorilla Robot is employed in some experiments.

  • 3944.在弗吉尼亚州从藻类生物柴油——新替代能源的开发

    [电力、热力、燃气及水生产和供应业] [2014-04-08]

     During the course of this work and immediately prior to commencing, we discovered that glycerol, a major by-product of the conventional transesterification reaction for biofuels, is not formed but rather three methoxylated glycerol derivatives are produced. These derivatives are high-value specialty green chemicals that strongly upgrade the economics of the process, rendering this approach as one that now values the biofuel only as a by-product, the main value products being the methoxylated glycerols. A horizontal agitated thin-film evaporator (one square foot heat transfer area) proved effective as the primary reactor facilitating the reaction and vaporization of the products, and subsequent discharge of the spent algae solids that are suitable for supplementing petrochemical-based fertilizers for agriculture.

  • 3945.手机网络数据在交通数据采集和远程货运卡车(地理范围)跟踪的应用

    [信息传输、软件和信息技术服务业] [2014-04-08]

    This study analyzed the potential of cell phone positioning techniques in freight trucks data collection and long-haul truckshed (geographic extent) tracking. The freight truck identification and tracking algorithms were developed by means of cell phone network data and the established freight truck analysis GIS to recognize the freight trucks and determine their geographic extent (trucksheds). A case study was conducted to illustrate the truckshed tracking process and verify the tracking result from the cell phone network.

  • 3946.SPARCCS—智能手机的辅助准备,指挥和控制系统

    [信息传输、软件和信息技术服务业] [2014-04-08]

    Maintaining an accurate common operating picture (COP) is a strategic requirement for efficient and successful missions in both disaster response and battlefield scenarios. Past practices include utilizing cellular, radio, and computer based communication methods and updating individual maps. A drawback of these practices has been interoperability of these devices as well as inaccurate reporting and documentation among different entities of the effort. Recent advances in technology have led to the utilization of collaborative maps for maintaining a COP amongst command centers. Despite the advantages this technique offers, it does not address the difficulties surrounding receiving reports from field entities as well as ensuring these entities also have good situational awareness. We are developing SPARCCS (Smartphone Assisted Readiness, Command, and Control System) to address these issues. We use smartphones in conjunction with cloud computing to extend the benefits of collaborative maps to mobile users while simultaneously ensuring that the command centers receive accurate, up-to-date reports from the field.

  • 3947.用于分级机器人的外部特征提取和西红柿分类的研究方法

    [电气机械和器材制造业] [2014-04-08]

    The color and shape feature are very important quality characteristic for classification of fruits. The dominant grading color histogram feature and radius normal angle histogram feature were presented in this paper. They can well represent the color and shape information of fruits respectively and are not sensitive to the changes of scale, translation and rotation. Experiment results showed both histogram features can effectively distinguish between different grade fruits and have high classification accuracy. They are suitable for real-time application.

  • 3948.水再生的膜生物反应器中生物膜硅包埋技术

    [电力、热力、燃气及水生产和供应业] [2014-04-08]

    To improve bioreactor design in these areas, we have demonstrated a technique linking advanced cell immobilization to hollow fiber membrane bioreactor. Porous silica immobilization of cells (biosilification) is a biocompatible, optically transparent encapsulation method used for high quality thin film deposition. Results indicate that encapsulated membrane-bound cells within biofilms are viable, retain their morphology, are metabolically active, and are physically trapped following biosilification. The resultant thin silica membrane is evenly distributed over the biofilm surface, reducing molecular diffusion limitations, and reinforcing the matrix.

  • 3949.4.0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.

  • 3950.新的全球生态系统的预先计算:对美国的竞争力和国家安全的影响

    [信息传输、软件和信息技术服务业] [2014-04-08]

    Computing and information and communications technology (ICT) has dramatically changed how we work and live, has had profound effects on nearly every sector of society, has transformed whole industries, and is a key component of U.S. global leadership. A fundamental driver of advances in computing and ICT has been the fact that the single-processor performance has, until recently, been steadily and dramatically increasing year over years, based on a combination of architectural techniques, semiconductor advances, and software improvements. Users, developers, and innovators were able to depend on those increases, translating that performance into numerous technological innovations and creating successive generations of ever more rich and diverse products, software services, and applications that had profound effects across all sectors of society.
