with the development of the network, people are more and more dependent on it and also have higher requirements on its convenience and manipulation. Based on Windows platform, long-range ordering system, which has taken advantage of Internet, enables people to select menu and to order food by local computer, meanwhile, no matter at any restaurant which is accessible to Internet, people could transfer and copy the menu. Different restaurant could set various passwords to operate the system. Ordering food and delivery service benefit much from visible interface as well as simple operation. © 2011 IEEE.

Cameras' miniaturization enable us feasible to capture photos and video at anywhere and anytime, even we wear them on human body and look the world in egocentric point of view. However, image quality degradation is caused by various factors in wearable environment, preprocess image acquired in wearable vision system is an unavoidable step. In this paper, we propose a new scheme to preprocess image sequence according to different quality of image frames in contiguous sequence. Firstly we detect image quality using hybrid methods, then classify them into some categories and given corresponding preprocess policy. We present experiment on a dataset collected within a cluttered environment, a prototype implementation validates its validity. © 2011 Springer-Verlag Berlin Heidelberg.

辉石和长石是玄武岩的主要矿物成分,辉石为含Fe,Ti,V等元素矿物,长石为富铝矿物。二叠系玄武岩火山间歇期间,大气中的强酸性气体被雨水转移到地表水之后就变为饱含CO2气雨水。在温暖至湿热的气候条件下,饱含CO2气雨水造成玄武岩中的富铝矿物分解首先形成高岭石、埃洛石等粘土矿物,而Fe,Ti,V等元素也因辉石等矿物的分解而迁移出来,并在高岭石等粘土矿物形成的吸附障中富集。与此同时,含铁矿物氧化分解形成针铁矿及赤铁矿。在雨量充足、海侵事件等的作用下,水位较高,风化壳下部处于较还原的条件下,铁被还原成易溶的二价状态或在有机质的作用下迁出风化壳,并在合适的地质条件(向斜构造)下富集,造成Fe(Ti,v)—铝等元素分离,并伴随铁矿、铝土矿的形成。

International Conference on Computational and Information Sciences (ICCIS)

作者： Yu Wang Xianguo Tuo College of Information Science and Technology Chengdu University of Technology Chengdu China College of Nuclear technology and automation enginerring Chengdu University of Technology Chengdu China

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.
