The aim of this study was to evaluate and position the perceptions of importance and performance of municipal solid waste management aspects and criteria. The study results propose dependence relations among four aspects and 33 criteria pertaining to metropolitan Taipei. Evaluation was based on linguistically described preferences and multiple aspects and criteria analysis; in particular, applied fuzzy set theory was used to evaluate linguistic vagueness, and the analytic network process was applied for dependence relations among the aspects and criteria. In order to compile managerial implications and concluding remarks, importance-performance analysis was conducted, using several mathematical techniques applied to the objectives as well as the participation and input of professionals and academicians. Overall results and concluding remarks are discussed. © 2010 Springer Science+Business Media B.V. Source

During late 1970s and early 1980s, Fresnel lenses have received more attention in the field of solar energy application. This paper briefly examines the Fresnel lens development since 1970s and investigates the losses inherent in the linear Fresnel lenses. The research develops the formulation that helps to quantify the linear lens' transmittance loss and prism-tip scattering loss and then derive a realistic model to simulate the measured data. In addition, the research has identified an elliptical-based lens that comes closest to the condition of minimum deviation. Such lens closely duplicates the curvature needed for maximum transmission. The researcher applies different design wavelengths to study the contribution of each wavelength interval on the receiving plane. © 2010 Elsevier Ltd. All rights reserved. Source

The balanced scorecard (BSC) is a multi-criteria evaluation concept that highlights the importance of performance measurement. However, although there is an abundance of literature on the BSC framework, there is a scarcity of literature regarding how the framework with dependence and interactive relationships should be properly implemented in uncertainty. This study proposes a hybrid approach: the analytic network process (ANP) is used to analyze the dependence aspects, the decision-making trial and evaluation laboratory (DEMATEL) is used to deal with the interactive criteria, and the fuzzy set theory is used to evaluate the uncertainty. The four BSC aspects and 22 criteria are evaluated for a private university of science and technology in Taiwan. The results show that student acquisition is the most influential and weighty criterion, and the annual growth in revenue is the most effective criterion. Managerial implications are also discussed, and concluding remarks are made. © 2010 Elsevier Ltd. Source

This investigation elucidates the properties of indium-tin oxide (ITO) thin films used as antireflection front electrodes in μc-Si/c-Si heterojunction (HJ) solar cells. The deposition conditions of ITO film by electron-gun evaporation were optimized for HJ solar cell applications. Microstructure, surface morphology, electrical and optical properties of these films were then characterized and analyzed. Next, the effects of substrate temperature on ITO film growth were discussed. The ITO thickness was optimized considering that the refractive index of μc-Si emitter layer optimizes its optical characteristics and HJ solar cell spectral response. The best HJ solar cell conversion efficiency was 16.4% with an open circuit voltage (Voc) of 0.645 V, fill factor (FF) of 0.73, and short circuit current density (J sc) of 34.8 mA/cm2. © 2010 Elsevier B.V.

This study proposes a combined fuzzy grey relational analysis method based to deal with study objective. This study objective is aimed to present a perception approach to deal with supplier evaluation of environmental knowledge management capacities (EKMC) with uncertainty and lack of information. The ranking of best supplier might be a key strategic direction of other suppliers prior to EKMC. The solving procedure is as follows, (i) the weights of criteria and alternatives are described both in qualitative and quantitative information using fuzzy set theory; (ii) using a grey relational analysis to result the ranking order for all alternatives; (iii) an empirical study of supplier ranking problem in EKMC are used to resolve with this proposed approach and the result indicates that optimal supplier is with higher protection of the environmental knowledge from inappropriate or illegal use or theft (C7) and from the best alternative supplier to study its criteria ranking. © 2009 Elsevier Ltd.
