4832.由惯性测量单元与一个手持EMI传感器集成提高鉴别性能
[计算机、通信和其他电子设备制造业] [2013-12-21]
We compared classification capabilities for handheld electromagnetic sensors that were deployed using either a grid-based template for spatial registration or an IMU-based positioning system. Demonstration data were collected at the Aberdeen Proving Ground using both systems. The two data sets were analyzed separately and submitted to the Institute for Defense Analyses for grading. The IMU-based positioning system involved in this demonstration is known as the Small Area Inertial Navigation and Tracking (SAINT) system. It was developed by ENSCO as part of an earlier ESTCP project and enhanced and integrated with the EM61HH sensor in support of this effort. The SAINT system consists of a Honeywell HG1900 IMU and a LEICA DMC. The Honeywell HG1900 IMU consists of orthogonally aligned MEMS accelerometers and gyroscopes that record 3-axis acceleration and rotation rates, respectively enclosed in an 8-cubic inch container. The LEICA DMC is employed to aid the IMU and constrain heading drift. The digital magnetic compass measures the strength and direction of a magnetic field and can be used to determine magnetic north in an environment free of additional magnetic fields. SAINT records all IMU and digital magnetic compass data onto an internal compact flash card.

4833.HEB焦平面成像技术的安全性和生物医学应用
[医药制造业] [2013-12-21]
We have demonstrated a low-noise heterodyne three-element focal plane array (FPA) at 1.6 THz consisting of NbN Hot Electron Bolometric (HEB) detectors, intimately integrated with monolithic microwave integrated circuit (MMIC) IF amplifiers in a single block. HEB technology is becoming the basis for advanced terahertz imaging and spectroscopic technologies for the study of biological and chemical agents over the entire terahertz spectrum. The use of FPAs is crucial for maximizing the detection speed in these applications.

The Eclipse Orion project's objective is to create a browser-based, open source, tool-integration platform, one entirely focused on developing for the web, in the web. Orion tools are written in JavaScript, they run in the browser, and its components are individually consumable. This article introduces you to Orion, and provides resources and commentary to help familiarize you with the tools.

[信息传输、软件和信息技术服务业] [2013-12-21]
What would I tell my friends and former teammates that I had been doing for the past 15 years? After some thought, I realized that my time as an Eagle had prepared me for a research career, in ways I would never have imagined. This article shares some of these similarities, to motivate others to reflect on their own careers and achievements, and perhaps make proactive changes as a result.

4837.核电站校准间隔时间延长的传感器校准监控研究
[电力、热力、燃气及水生产和供应业,计算机、通信和其他电子设备制造业] [2013-12-21]
Currently in the United States, periodic sensor recalibration is required for all safety-related sensors, typically occurring at every refueling outage, and it has emerged as a critical path item for shortening outage duration in some plants. Online monitoring can be employed to identify those sensors that require calibration, allowing for calibration of only those sensors that need it. International application of calibration monitoring has shown that sensors may operate for longer periods within calibration tolerances. This issue is expected to also be important as the United States looks to the next generation of reactor designs (such as small modular reactors and advanced concepts), given the anticipated longer refueling cycles, proposed advanced sensors, and digital instrumentation and control systems. The U.S. Nuclear Regulatory Commission (NRC) accepted the general concept of online monitoring for sensor calibration monitoring in 2000, but no U.S. plants have been granted the necessary license amendment to apply it. This report presents a state-of-the-art assessment of online calibration monitoring in the nuclear power industry, including sensors, calibration practice, and online monitoring algorithms. This assessment identifies key research needs and gaps that prohibit integration of the NRC-approved online calibration monitoring system in the U.S. nuclear industry. Several needs are identified, including an understanding of the impacts of sensor degradation on measurements for both conventional and emerging sensors; the quantification of uncertainty in online calibration assessment; determination of calibration acceptance criteria and quantification of the effect of acceptance criteria variability on system performance; and assessment of the feasibility of using virtual sensor estimates to replace identified faulty sensors in order to extend operation to the next convenient maintenance opportunity.

4839.悬浮的纳米粒子上的向列型主机的日Frederiks阈值的影响
[计算机、通信和其他电子设备制造业] [2013-12-21]
In recent years several papers reported an enhanced dielectric anisotropy when ferroelectric particles were suspended in a liquid crystal. These results seem to be sensitive to the liquid crystal used and the preparation method of the ferroelectric particles. In this paper we compare different preparation methods of suspended barium titanate in two different liquid crystal hosts. As a control experiment we have followed similar preparation steps with non- ferroelectric silica particles. In all cases we found a broadening of the optical Frederiks transition but no change in the dielectric anisotropy. Raman spectroscopy has been used to investigate the loss of tetragonal structure in the barium titanate as a function of milling time and particle size. As reported in the earlier literature barium titanate does not exhibit a well-defined tetragonal crystal structure below a certain particle size and loses its ferroelectric features. This provides a simple rationalisation for the absence of any dielectric enhancement.

4840.课题专家研究
[信息传输、软件和信息技术服务业] [2013-12-21]
We suggest a method to automatically evaluate employees' subject matter expertise in knowledge management systems. The approach stems from several conclusions that arose in extensive research of subject matter experts and their expertise. We find that self-reported expertise is biased and constantly changing. We, furthermore, observe that automatic methods to infer expertise perform about as well as self-reported profiles. The crux of the proposed method is to combine automatic inference expertise with the benefit of the expert's opinion, and to do so periodically so the profile remains accurate and fresh.
