Risk management includes phases such as risk identification, risk assessment and risk control. Little work has focused on risk summarization, which is a useful phase of risk management. Risk summarization means a list of occurred risks, risk summarization can also means relative documentation for risk management actions. This study presents summarization indices to evaluate the risk management efficiency. The indices include expected success rate, risk identification ratio, actual key risk ratio, actual key risk identification ratio, etc. The study aims at helping to fill a vacancy of risk summarization in risk management domain.

Front-end converters for distributed power system (DPS) applications are extensively used in telecommunication systems to supply load converters and to charge batteries to provide backup energy during power grid blackouts. This paper explores the main features of the two-switch three-level boost rectifier operated in discontinuous conduction mode (DCM). The main contributions are reduced voltage stress and improved efficiency. Control strategies and design guidelines are provided in this paper. Because of the voltage stress reduction brought about by using a three-level topology, MOSFETs can be used to simultaneously increase the switching frequency and efficiency of the power factor correction (PFC) circuit. The discussion is supported by simulation results obtained from a 6.3kW prototype. © 2011 IEEE.

This paper analyzes characteristics of CDMA2000 reverse link HPSK modulation pattern, establishes the model of mobile station transmitted signals and observation station received signal and deduces flow of capture using R-PICH. In order to analyze quantitatively the influence to capture performance of detection threshold, integration time, signal-to-interference ratio and vestigial carrier, in the Neyman-Pearso criterion, the functional relationship between false-alarm probability and detection probability and the computational formula, are deduced, which provides theoretical support for optimal design of parameters. Aim at the impact of inserted forward power control group and vestigial carrier, the solution of short-term coherent integration associating with long-term incoherent accumulate is proposed, and the calculation method of capture performance in this mode is deduced. Simulation results show that the scheme can achieve stable capture toward mobile station under low SNR and effectively promote capture performance. © 2011 IEEE.

This paper mainly deals with the problem of detecting a target in SIRV clutter with steering vector mismatches. Assuming that the mismatch of the steering vector is satisfied the conic constraint, the generalized likelihood ratio test (GLRT) is devised, and the geometry explain is presented for the derived solution. Meanwhile, fixed point estimate (FPE) of the covariance structure is adopted using the secondary data. Finally, we assess the performance of the derived test by Monte Carlo techniques, and several numerical results show that the derived test is consistent with the famous normalized matched filter (NMF), and has the ability to reject high mismatched signals. © 2011 Global IT Research Inst.

The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle θ13 with a significance of 5.2 standard deviations. Antineutrinos from six 2.9 GWth reactors were detected in six antineutrino detectors deployed in two near (flux-weighted baseline 470 m and 576 m) and one far (1648 m) underground experimental halls. With a 43 000 ton–GWth–day live-time exposure in 55 days, 10 416 (80 376) electron-antineutrino candidates were detected at the far hall (near halls). The ratio of the observed to expected number of antineutrinos at the far hall is R=0.940±0.011(stat.)±0.004(syst.). A rate-only analysis finds sin 22θ13=0.092±0.016(stat.)±0.005(syst.) in a three-neutrino framework.

由于探测器技术的快速发展，使得辐射测温的测温下限不断下延。许多国家计量院已经研制了InGaAs近红外辐射温度计作为1000℃以下辐射温度计标准器。而该辐射温度计的分度需要中低温固定点和Sakuma方程来实现。为了满足近红外辐射温度计量值溯源的需求，各个国家计量院相应地建立了中低温固定点黑体辐射源(铟点、锡点、锌点、铝点和银点)。文章从InGaAs辐射温度计和中低温固定点黑体的实验装置、仪器性能及测试结果等方面系统综述了先进国家计量院中低温辐射测温的研究进展，还介绍了中国计量科学研究院的InGaAs近红外辐射温度计以及中低温固定点黑体的研究进展。

With the development of VLSI and intelligent technology, the design idea and implementation scheme for real-time new nuclear information processing system are proposed. Based on ARM+WinCE+UART, the portable energy-spectral measurement system can analysis the nuclear signal characteristics from different detectors, to determine the physical nature of radiation. The development of software modules under Windows CE are elaborated in detail, including the serial port driver, UART interrupt handling and flow control, custom communication protocols etc. It describes the application to communicate with hardware implementations through software interface design. The test result shows that the system can not only complete the analysis of the signal amplitude but also achieve other functions such as the timecharacteristics of nuclear signal, waveform recognition, signal sorting selection etc.

In this paper, we proposed a robust lane detection method. This method uses the globalized probability of boundary (gPb) algorithm as boundary detector and non-unique B-spline (NUBS) as the road model. The gPb algorithm combines the local information, like brightness, color and texture features, with global information derived from spectral partitioning and is robust against shadow, and illumination varying in road boundaries detection. NUBS model is flexible enough to model the most of roads, include highways and rural ways, while taking account of the perspective effect. This method contains three main steps: first, we use gPb to detect the boundaries of the objects in the resized captured images, and then, take use of the parallel property of the road boundaries in ground images to find the knot sets of NUBS model for two sides of the road boundaries. Finally, we make the knots as initial boundaries and push them to the more accuracy boundaries in the canny edge map image using the snake algorithm.
