Recently, large-scale diode grids have received much attention with regard to spatial electromagnetic (EM) field protection of electronic systems. The distributed nature of diode grids and the large number of elements (usually hundreds or even more) pose a challenging problem for numerical modeling. In this paper, a hybrid field-circuit simulation combining the method of moments and a causal convolution...
In the watermarking schemes, Just Noticeable Distortion (JND) model provides an efficient method to keep the balance between watermark's imperceptibility and robustness. Traditional JND models are not as perfect as they should be. Edge detection, which extracts content features well, improves the performance of JND models. In this paper we explore the reasons and simulate JND models based on edge...
By selecting customers' credit risk indicators of the domestic textile industry on the electronic trading market in China and using factor analysis method, clustering method, and ordered-logit model, it can be concluded that the comprehensive evaluation of customers' credit status is measured scientifically in B2B market. Therefore, customers' credit risk management is made effectively in accordance...
The sealing process of packer rubbers is analyzed by finite element methods with the ANSYS software in the paper. It introduces in detail the principles of the packer's sealing, elaborates the elementary theories of the finite element analysis and the methods to determine the model parameters, establishes the finite element analysis models of the packer rubbers, analyzes the relationship between the...
To deal with the traditional problem of N-player iterated prisoner's dilemma (NIPD), this paper proposes a classify-coding scheme of individual strategy, related to the thoughts of people in reality. The simulation experiments indicate that the NIPD model based on the new strategy features a dynamic, successive multi-phases equilibrium. A quantitative analysis on multi-phases equilibrium is made,...
Due to the application of operations support system (OSS), the telecom operators increasingly have the capability to accumulate huge amounts of customer data in large databases. However, much of the useful marketing insights into customer characteristics and their purchase patterns are largely hidden and untapped. Current emphasis on customer relationship management makes the marketing function an...
This paper explores e-government service adoption in Taiwan and citizen satisfaction, and builds a fitting grey relation analysis model for the evaluation of bureau/department performance. This study collected 10,652 cases between 2003/7/15 - 2007/4/30 from satisfaction quantity tables in the Kaohsiung City Service On Line System (KCSOLS) database. The results of e-government research imply that,...
