With the rapid development of power system and the continuous expansion of the scale of power grids, problems such as heavy maintenance workload, repetitive modeling and low redundancy and accuracy of basic data are emerging in the traditional method of centralized modeling in control center. In this paper, a two-level distributed modeling system is presented to solve these problems, which moves parts...
Perceived service is regarded as an antecedent of customer satisfaction, and most of studies use linear model to estimate the effect of perceived service on customer satisfaction. However, nonlinear relationship between perceived service and customer satisfaction may exist according to previous theories. In this study, we use a bank customer sample of 2500 people and a refrigerator customer sample...
This paper was to investigate the application of item response theory to specify an appropriate item response model for the equating of the mixed-format of multiple-choice items and open-ended items, since equating is the precondition of the development of an item bank for the Computer-Based College English Placement Test. It was shown that the equating approach based on common-item nonequivalent...
According to the complex information of the teaching quality evaluation system, this thesis constructs evaluation index system, establishes teaching evaluation method based on Set Pair Analysis to rationally evaluate the teaching quality and gives suggestions for improvement. First, it constructs a teaching quality evaluation index system based on the construction of teaching practice, divides into...
An improved adaptive generalized morphological filter is proposed in this paper. With respect to the different types of interference possibly encountered in power system signal, detailed investigations are carried out through numerical simulation, regarding the impacts of the amplitude and width of a structure element on the performance of the improved adaptive generalized morphological filter. With...
