43513.建立一个软件定义无线电的实验测试平台
[信息传输、软件和信息技术服务业] [2013-10-08]
Software-defined radios (SDRs) provide researchers with a powerful and flexible wireless communications experimentation platform. GNU Radio is the most popular open-source software toolkit for deploying SDRs, and is frequently used with the Universal Software Radio Peripheral (USRP). There is significant complexity involved in setting up GNU Radio with the USRP; therefore, in this report, we describe the key steps to take (and pitfalls to avoid) in order to successfully establish such an SDR testbed.

43515.使用软件定义的无线电被动射频识别标签的空间识别
[信息传输、软件和信息技术服务业] [2013-10-08]
This research seeks to utilize a software defined radio for the detection and spatial identification of radio frequency identification tags. A software defined radio (SDR) is a hardware platform that provides the ability to broadcast and receive across multiple bands of the radio frequency (RF) spectrum, depending on the RF front end and software profile loaded on it. The focus of the research will be on the spatial identification (SID) of passive radio frequency identification tags (RFID). The research is applicable to many areas of day-to-day operations both within the DoD and industry. Flight line safety tracking of equipment and personnel, as well as perimeter defense, are two areas that may benefit from this technology. One dual-purpose, civilian and military, application would be the tracking and locating of inventory within a warehouse. The research developed and implemented a SID process, and proved its suitability to quickly identify and locate target tags within range. A profile of the system's capabilities and limitations in a laboratory environment was developed, including range, sensitivity, and accuracy.

43516.对一个支持通用NEAMS软件堆栈
[信息传输、软件和信息技术服务业] [2013-10-08]
The NEAMS IPSC's are developing multidimensional, multiphysics, multiscale simulation codes based on first principles that will be capable of predicting all aspects of current and future nuclear reactor systems. These new breeds of simulation codes will include rigorous verification, validation and uncertainty quantification checks to quantify the accuracy and quality of the simulation results. The resulting NEAMS IPSC simulation codes will be an invaluable tool in designing the next generation of Nuclear Reactors and also contribute to a more speedy process in the acquisition of licenses from the NRC for new Reactor designs. Due to the high resolution of the models, the complexity of the physics and the added computational resources to quantify the accuracy/quality of the results, the NEAMS IPSC codes will require large HPC resources to carry out the production simulation runs.

43517.软件定义的全球定位系统(GPS)接收机的精确打击武器的应用程序框架
[信息传输、软件和信息技术服务业] [2013-10-08]
Gun-launched munitions rely heavily on the global positioning system (GPS) receivers for position, velocity, and “up-finding” in their guidance, navigation, and control (GN&C) systems. These receivers account for substantial cost in the GN&C electronics due to the contractor intellectual property and non-recurring engineering (NRE) costs. Typically, the designs are not optimized for gun-launched munitions, but rather as general purpose receivers for missiles, unmanned aerial vehicles, aircraft, man-portable location systems, and vehicles. Due to the high launch dynamics, short time of flight, high spin rate, etc., the general purpose receivers have trouble acquiring and locking on the weak GPS signals. To address these challenges, software algorithms tailored to the flight dynamics can assist in the basic features of the receiver as well as provide jamming and spoofing immunity. In this report, a software-defined radio (SDR) approach is used for the development of global navigation satellite systems (GNSS) receivers. This approach provides an evaluation capability for algorithm development and evaluation that is nearly hardware agnostic.

43518.一个案例研究:使用云计算技术改善DHRA-DMDC物理访问软件DBIDS
[信息传输、软件和信息技术服务业] [2013-10-08]
The U.S government has created and been executing an Identity and Management (IdM) vision to support a global, robust, trusted and interoperable identity management capability that provides the ability to correctly identify individuals and non-person entities in support of DoD mission operations. Many Directives and Instructions have been issued to standardize the process to design, re-designed new and old systems with latest available technologies to meet the vision's requirements. In this thesis we introduce a cloud-based architecture for the Defense Biometric Identification System (DBIDS), along with a set of DBIDS Cloud Services that supports the proposed architecture. This cloud-based architecture will move DBIDS in the right direction to meet Dod IdM visions and goals by decoupling current DBIDS functions into DBIDS core services to create interoperability and flexibility to expand future DBIDS with new requirements. The thesis will show its readers how DBIDS Cloud Services will help Defense Manpower Data Center (DMDC) easily expanding DBIDS functionalities such as connecting to other DMDC services or federated services for vetting purposes. This thesis will also serve as a recommendation of a blue- print for DBIDS architecture to support new generation of DBIDS application. This is a step closer in moving DMDC Identity Enterprise Solution toward DoD IdM realizing vision and goals. The thesis also includes a discussion of how to utilize virtualized DBIDS workstations to address software-deployment and maintenance issues to resolve configuration and deployment issues which have been costly problems for DMDC over the years.

43519.TriBITS生命周期模型(版本1.0):计算科学与工程研究和应用数学软件的一个精益和敏捷的软件生命周期模型
[信息传输、软件和信息技术服务业] [2013-10-08]
Software lifecycles are becoming an increasingly important issue for computational science & engineering (CSE) software. The process by which a piece of CSE software begins life as a set of research requirements and then matures into a trusted high-quality capability is both commonplace and extremely challenging. Although an implicit lifecycle is obviously being used in any e ort, the challenges of this process-respecting the competing needs of research vs. production-cannot be overstated.

43520.降低软件密集型发展项目风险的创新方法
[信息传输、软件和信息技术服务业] [2013-10-08]
Since 1973, nearly 80of DoD ACAT I programs have experienced cost overruns, coupled with a four-out-of-five chance of not fielding capability to the warfighter on time. With the DoD acquisition reforms of the past two decades, the probability of program success (PoPS) rate is improving. To continue improving PoPS, program management tools and techniques need to develop and become institutionalized to monitor software-intensive-based capability control, and logic development efforts. A lack of sufficient tools to monitor software development costs and performance to the integrated baseline drives uncertainty and risk. The earned value management system (EVMS) approach lacks meaningful measures for software-intensive development programs and 'you can't control what you can't measure' (DeMarco, 1986, p. 58). Using commercially available (often freeware) tools, a robust set of automated managers can measure near real-time progress and identify trouble areas early in the software development process to allow meaningful correction to occur. This paper explores agile sprint development and continuous integration and test best practices, and the potential for an innovative approach of intertwining the two to reduce risk and increase PoPS. The presentation includes 20 briefing charts.
