This paper, for the first time, optimizes the characteristics of capacitance-voltage (C-V) of germanium (Ge) metal-oxide-semiconductor field effect transistors (MOSFETs) with aluminum oxide (Al2O3) by using a semiconductor-device-simulation-based multi-objective evolutionary algorithm (MOEA) technique. By solving a set of 2D semiconductor device transport equations, numerical simulation is intensively performed for the optimization of the C-V curve of Ge MOSFET devices. To optimize the capacitance of Ge MOSFETs with respect to the applied voltage, by minimizing the total errors of the C-V curve between the device simulation and a given specification (and experimentally measured data), the thicknesses of Al2O3 and GeO2, the work function of gate electrodes, the distribution range of channel doping, the dielectric constants of Al2O3 and GeO2, and the source/drain doping concentration are considered in the process of optimization. The semiconductor device simulation and the MOEA method are integrated and performed based on a unified optimization framework. According to the sharp variation characteristics of the C-V curve, except for using a residual sum of squares (RSS) (i.e., the sum of squares of residuals) as an objective function, physical key parts of the curve are also considered in the optimization problem. The engineering results of this study indicate that the semiconductor-device-simulation-based MOEA method shows great performance to optimize the parameters, which not only minimize the objective values but also match the curve shape.

Analysis of variance is one of the most frequently used statistical analyses in the behavioral, educational, and social sciences, and special attention has been paid to the selection and use of an appropriate effect size measure of association in analysis of variance. This article presents the sample size procedures for precise interval estimation of eta-squared and partial eta-squared in fixed-effects analysis of variance designs. The desired precision of a confidence interval is assessed with respect to (a) the control of expected width and (b) the tolerance probability of interval width within a designated value. In addition, sample size calculations for standardized contrasts of treatment effects and corresponding partial strength of association effect sizes are also considered.

In the severe recession in journalism, professional news sites are facing the challenge of increasing their competitive advantage. In this study, a resource-based approach was used to interview 12 top executives of leading news sites and portals in mainland China and Taiwan. The data were analyzed to determine the inimitable resources that enabled them to achieve competitive advantages and how these resources varied under different market conditions. The results identified property-based and knowledge-based resources that were developed by the news sites in reaction to the quickly changing environment of technology and media. Particular differences in communist and capitalist ideology between mainland China and Taiwan, respectively, and their effects on comparative resources are also discussed.
