This paper addresses the robust stability test problem for discrete time-delay systems subjected to uncertainties. By using Lyapunov stability theorem associated with solution bound of Lyapunov equation, a concise criterion is presented to guarantee the robust stability of the time-delay systems. Then, this approach is applied to discuss the same problem for time-delay systems with nonlinear uncertainties. A robust stability condition is also obtained. The feature of these present criteria is that they are independent of any Lyapunov equation although the Lyapunov approach is adopted. © ICIC International 2011.

An optimum shape design problem in simultaneously designing the shapes of interfacial surfaces among three conductive bodies in a three-dimensional domain, based on the desired system heat flux and domain volume, is examined in the present work. The Levenberg-Marquardt method (LMM), B-Spline surface generation technique together with the commercial code CFD-ACE were utilized to solve the inverse geometry problem. The validity of this algorithm is examined using the numerical experiments. Different combinations of conductive bodies and desired system heat fluxes were given in the numerical test cases to justify the validity of the algorithm in solving the three-dimensional inverse design problem. Finally, it is concluded that when the interfacial surfaces are well designed, the effective system heat flux can be increased significantly. © 2011 IEEE.

The oriental sucking barb, Garra orientalis, is a small to moderate-sized freshwater fish. In this study, the complete mitochondrial genome of G. oriental was successfully sequenced for the first time with total length of 17,288bp. The genome structure consists of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA (tRNA) genes and a control region. Moreover, tandem repeat unit ranged from 259 to 260bp (repeated 3-4 times) was identified in the control region among G. orientalis individuals. © 2013 Informa UK Ltd.

A thermal tomography problem, i.e. the shape identification problem or inverse geometry problem, in estimating the interfacial geometry for a three-dimensional multiple region domains is examined in this study based on the Conjugate Gradient Method (CGM). The accuracy of this thermal tomography analysis is examined using the simulated temperatures measured by an imaginary infrared scanner. Different temperature measurement positions and errors are considered in the numerical experiments to justify the validity of the present algorithm in solving the three-dimensional thermal tomography problem. Finally it is concluded that the reliable interfacial configurations can be estimated by the CGM. © 2010 Publishing House for Journal of Hydrodynamics.

This study investigated the effects of ambient illumination conditions (illumination color and illumination intensity) and background color on visual performance (character identification and reading comprehension) with TFT-LCD screens. Results of Experiment 1 indicated that all the three independent variables had significant effects on mean percentage of character identification. Mean character identification performance was best under white light, 500 lux, and blue background. In general, the backgrounds with primary colors had better mean character identification performance than the middle-point colors and gray. Results of Experiment 2 indicated that the illumination intensity and background color had significant effects on mean text comprehension performance for reading comprehension. Mean text comprehension performance were higher under 500 lux and blue background. The backgrounds with primary colors had better mean correct answers than the gray background. According to the results, white light, normal ambient illumination and a background with primal colors seemed to be the optimal conditions. If the yellow ambient light is necessary, using blue as the TFT-LCD background color of will provide better performance. The Pearson product-moment correlation coefficient indicated that short-term visual task measurement might be suitable to evaluate the visual performance. © 2013 Elsevier B.V. All rights reserved.
