Issue date:July 2011 Publication year:2011 Pages:1975-1983 Language:Chinese ISSN:10007598 Document type:Journal article (JA) Publisher:Academia Sinica, Wuhan, 430071, China Abstract:In order to improve the understanding of soil arching effect in the piled embankment, a series of three-dimensional model tests were carried out. The stress reduction ratio and the vertical stress distribution in the embankment fill were studied in detail. Based on the measured and the computed results, the applicability of Terzaghi method and Hewlett & Randolph method were verified. Three-dimensional finite element analysis was also performed in this research; the computed orientation of maximum principal stresses, the stress level and the settlement pattern were analyzed in detail. Based on the test and numerical results, it is found that the value of stress reduction ratio computed by Terzaghi method is closed to that of Hewlett & Randolph method; but the vertical stress distributions of the two methods are different considerably. If the failure surface observed from the numerical result is used, the prediction of vertical stresses using Terzaghi's method is found to be coincident with the measured value.

Issue date:July 1, 2011 Publication year:2011 Pages:5290-5295 Language:English ISSN:00032700 CODEN:ANCHAM Document type:Journal article (JA) Publisher:American Chemical Society, 2540 Olentangy River Road, P.O. Box 3337, Columbus, OH 43210-3337, United States Abstract:A novel photoelectrochemical sensor for detection of the organophosphorus pesticide (OP) dichlofenthion using nanometer-sized titania coupled with a screen-printed electrode is presented. Nonelectroactive dichlofenthion can be indirectly determined through the photocatalytical degradation of dichlofenthion with nanometer-sized titania. The electrochemical characterization and anodic stripping voltammetric performance of dichlofenthion were evaluated using cyclic voltammetric (CV) and differential pulse anode stripping voltammetric (DPASV) analysis, respectively. DPASV analysis was used to monitor the amount of dichlofenthion and provide a simple, fast, and facile quantitative method for dichlofenthion. Operational parameters, including the photocatalysis time, pH of buffer solution, deposition potential, and accumulation time have been optimized. The stripping voltammetric response is linear over the 0.02-0.1 and 0.2-1.0 μmol/L ranges with a detection limit of 2.0 nmol/L. The assay result of dichlofenthion in green vegetable with the proposed method was in acceptable agreement with that of the gas chromatograph-mass spectrometer (GC-MS) method. The promising sensor opens a new opportunity for fast, portable, and sensitive analysis of OPs in environmental samples. © 2011 American Chemical Society.

Issue date:July 2011 Publication year:2011 Article number:079201 Language:English ISSN:16741056 Document type:Journal article (JA) Publisher:Institute of Physics Publishing, Temple Circus, Temple Way, Bristol, BS1 6BE, United Kingdom Abstract:In terms of the characteristic topology parameters of climate complex networks, the spatial connection structural complexity of the circulation system and the influence of four teleconnection patterns are quantitatively described. Results of node degrees for the Northern Hemisphere (NH) mid-high latitude (30° N-90° N) circulation system (NHS) networks with and without the Arctic Oscillations (AO), the North Atlantic Oscillations (NAO) and the Pacific-North American pattern (PNA) demonstrate that the teleconnections greatly shorten the mean shortest path length of the networks, thus being advantageous to the rapid transfer of local fluctuation information over the network and to the stability of the NHS. The impact of the AO on the NHS connection structure is most important and the impact of the NAO is the next important. The PNA is a relatively independent teleconnection, and its role in the NHS is mainly manifested in the connection between the NHS and the tropical circulation system (TRS). As to the Southern Hemisphere mid-high latitude (30° S-90° S) circulation system (SHS), the impact of the Antarctic Arctic Oscillations (AAO) on the structural stability of the system is most important. In addition, there might be a stable correlation dipole (AACD) in the SHS, which also has important influence on the structure of the SHS networks. © 2011 Chinese Physical Society and IOP Publishing Ltd.

Issue date:July 2011 Publication year:2011 Pages:482-489 Language:Chinese ISSN:10020446 CODEN:JIQIER Document type:Journal article (JA) Publisher:Chinese Academy of Sciences, 90, Sanhao Jie, Shenyang, 110003, China Abstract:A method of dynamic hand gesture recognition based on SURF (speeded up robust feature) tracking is proposed. The main characteristic is that the hand trajectory is described only by tracking the dominant movement directions of matched SURF points in adjacent frames with no need of the previous detection and segmentation of the hand region. The dynamic hand gesture is then modeled by a series of trajectory direction data streams after time warping. Accordingly, the data stream clustering method based on correlation analysis is developed to recognize a dynamic hand gesture and to speed up calculation. The proposed algorithm is tested on 26 alphabetic hand gestures and yields a satisfactory recognition rate, which is 87.1% on the training set and 84.6% on the testing set. Its successful application to the motion control of our self-developed robot Hunter also establishes the effectiveness of the approach.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:The binomial tree method (BTM), first proposed by Cox et al. (1979) [4] in diffusion models and extended by Amin (1993) [9] to jumpdiffusion models, is one of the most popular approaches to pricing options. In this paper, we present a binomial tree method for lookback options in jumpdiffusion models and show its equivalence to certain explicit difference scheme. We also prove the existence and convergence of the optimal exercise boundary in the binomial tree approximation to American lookback options and give the terminal value of the genuine exercise boundary. Further, numerical simulations are performed to illustrate the theoretical results. © 2011 Elsevier B.V. All rights reserved.
