Discontinuous curve fitting is the task of finding a suitable function which is best fitting to a given set of data points. Once the expression forms of function and of error are determined, curve fitting is regarded as an optimization problem. In this paper, a measurement method is proposed to optimize curve fitting problem. The proposed method is based on genetic algorithm, namely GAOCF (GA based Optimizer for Curve Fitting). The main advantage is that the proposed GA based method can skip the local optimum solutions, and find out better solution in a huge searching space. Consequently, some arc data will be used to verify the feasibility and effectiveness of the GA based measurement method proposed in this paper.
Taiwan’s solar power industry has developed midstream cell manufacturers with a certain share of the global market. Therefore, examining the operating performance of Taiwanese solar cell manufacturers has become vital for the international competitiveness of Taiwanese manufacturing. This study used a two-stage data envelopment analysis (DEA) method to measure the operational abilities and profitability of Taiwanese solar cell manufacturers. The research period for this study was between 2009 and 2011. This study’s primary contribution is in constructing a performance evaluation model for the solar cell industry to assist relevant manufacturers in the Taiwanese solar power industry in formulating operational strategies.
Japanese vocabulary proficiency is directly related to Japanese language proficiency, and the learning and evaluation of Japanese vocabulary is vital in Japanese learning. To evaluate the learners’ Japanese vocabulary proficiency, in this study, we propose an effective method for evaluating Japanese vocabulary and implement it into a system. To prove the evaluation ability of the proposed method and implemented system, we conducted an experiment involving 80 students from the Japanese Group of the department of applied foreign languages of a senior high school to investigate the effectiveness of the method and system. The results of this study confirmed that (1) the reliability and validity of the proposed Japanese vocabulary evaluation method and system are favorable; and (2) the correlation coefficient between the experimental results and the students’ academic performance is higher than 0.80. Theoretically, the multidimensional Japanese vocabulary quotient model proposed herein can be the basis for Japanese vocabulary detection. Practically, the low-cost and rapid Japanese vocabulary evaluation system developed is applicable to educational evaluation, whereas the technical evaluation method and system for Japanese vocabulary can improve the efficiency and effectiveness in evaluating the Japanese vocabulary of learners.
This work aims to make use of information technology to improve present test platform, proposing TPIF(Test Process Integration Framework) as an integrated interaction framework for enginer, quality controller, corporate vendor, and manager to test data and analyze information. Also, it suggests a practicable system framework and implementation case to illustrate the integration and reconciliation degree of TPIF. In TPIF, a component utilizes ATML as the basic format for test information is designed to transform ATML message to Web Services rapidly, upgrading the reliability of test information and be a reference for relevant research. The implication of this proposed framkwork is to mature the integration of test imformation; besides, the engineers could have better understanding of the completed status in production process through combining ATML and information flow , as well as enhancing the yield rate and reduce the possibility of damage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
