E-learning implemented in distance education has been developing rapidly in China since 1999. Along with the rapid development, China modern distance education encountered many difficulties. How to provide personalized learning support for massive distance learners is one of the difficulties. Researchers have suggested that learning style as habitual ways of perceiving and processing information has...
With the ability of data mining and reasoning, Bayesian network could well solve the problems with uncertainties and incompletion, and the result of assessment is closer to the real condition. Therefore, the Bayesian network is to solve the problems in battle damage assessment. The paper firstly analyses the damage indexes and variables of UAV-to-ground attacking. Given conditional probability by...
The fabrication of GaAs nanograss to mimic the moth-eye structure have been demonstrated using a simple, one-step, and mask-less plasma etching based approach. The GaAs nanograss exhibits remarkable broadband antireflection properties, which arise from length variation of nanograss due to the graded refractive index between air and GaAs. Moreover, GaAs nanograss show less sensitivity to transverse...
Hyper-heuristics solve problems by manipulating low-level domain-specific heuristics. The aim is to raise the level of generality of the algorithm to solve problems in different domains. In this paper we propose a hyper-heuristic based on Variable Neighborhood Search (VNS), which consists of two main steps: shaking and local search. Shaking disturbs solutions, and then local search seeks for the local...
When the numbers of international students has become an indicator of the institutional and global competitiveness, the continuance of the institution existence relied in the quality of education. This research study is exploring the rationale of international students in choosing the Private Higher Education Institutions in Malaysia. An in-depth interview with industry expertise had been conducted...
Wavelet shrinkage is an image denoising technique based on the concept of thresholding the wavelet coefficients. The key challenge of wavelet shrinkage is to find an appropriate threshold value, which is typically controlled by the signal variance. To tackle this challenge, a new image shrinkage approach is proposed in this paper by using a variance field diffusion, which can provide more accurate...
This paper addresses the super-resolution image reconstruction problem with the aim to produce a higher-resolution image based on its low-resolution counterparts. The proposed approach adaptively adjusts the degree of regularization using the saliency measure of the local content of the image. This is in contrast to that a spatially-invariant regularization is used for the whole image in conventional...
Individuals from different regions normally bear different cultural norms and values, and these variations would in turn affect their behavior and attitude with the computing system. However, though the cross-cultural study has been performed in other areas (e.g., e-commerce websites), few have identified its influence on users' behavior in social network sites (SNS). With the increasing popularity...
This paper studies a large supermarket chains, which using of logistics simulation software ExSpect to test the model performance and simulation experiment. It constructs logistics distribution business process model based on Petri net tools, analyzes the enterprise distribution business process, and then puts forward the improvement process optimization scheme according to the simulation data. Comparing...
In this research, we used EEG signals to analyze gender processing with the ERSP method. Not only facial images, but also images of clothing and shoes, were used. We applied the ICA method to obtain a gender-related component which appeared quite significant in the majority of electrode sites for the occipital lobe. This showed differences of energy between the two genders, even for the clothing and...
Slope is a natural geography widely exists in the world. Reforms of the nature also lead to vast artificial slopes. Under the effect of inner force and various external loads, the stress-strain relationship of the slope is continuously changing and leads to kinds of destabilizing accidents. Accidents of slumping spread across the world, bringing in great loss to many countries and districts. Therefore,...
Coalbed gas is a kind of special gas of containing mass of CH4, which is the host-coal rocks formed then reserved in the coalbed in the process of coalification. The gas direct diffuse into the air in exploiting coal because less study on diffusion mechanism of coalbed gas. It could make the risk of gas explosion, environment pollution and the resources wasted. Then, it is provided significance of...
Continuing education has become a way with which organization invests employees as human capital, and individual secures personal career and enhance professional development. Working people choose to return schools for either getting advanced degrees or enhancing their professional knowledge and skills in order to secure their jobs. With all the aspects for human capital investment in organizational...
Roller coaster is a high-speed entertainment. Comfortable and safety of the bogies are affected severely by the roller coaster fast moves relative to the track. The model of roller coaster is established in ADAMS, which can provide an excellent foundation for the motion analysis, dynamic analysis and security assessment. Expound the principal problem of modeling technology, dynamic analysis at normal...
In this paper, we study the market reaction to the earnings forecasts revision. We find that the forecasts of earnings revisions have significant information content and the market is more sensitive to the firms who forecast bad news originally which manifest more in the revision to the opposite direction. Additionally, this view is attested by the CAR for different windows length.
Optimal design with the production cost of the manufacturing technology is carried out by the Dijkstra algorithm, the best processing lines and the relevant technological methods with condition of the lowest production cost are obtained. Practical instance with CAD procedure is given.
The research investigated the rules relevant with leaving reasons and personal characteristic variables of nursing staff by rough set theory (RST). RST can discover the important facts hidden in the data and describe them with natural language. That is it can describe the information provided by researchers in a broad sense and delete the redundant part of original data for the decision rules setting...
Genetic algorithm and ant colony algorithm are the methods for solving winner determination problem in combinatorial auctions. Because of their mutual compensability: ant colony algorithm can make up for the shortage of feedback information and the slowness of solving solution in genetic algorithm, while genetic algorithm is able to enhance the speed of ant colony algorithm in solving solution and...
Optimal design of auction is one of hot research topics in the auction theory. During recent years, shill bidding has increased substantially with the explosion in the number of online auctions. This paper designs the optimal online auction with shill bidding and open reserve price. Many optimal auction models have assumed that the number of potential bidders is constant and known. And in these optimal...
Sugeno integral is used as an aggregation tool in information fusion which could be regarded as the inverse problem of information fusion as well as in nonlinear multi-regressions and nonlinear classification. Introducing more types of nonlinear integrals with provide more choices for various of objectives and components in these problems. However, when sample space is huge, regarding needs the information...
