Based on the technology acceptance model, the paper developed a conceptual model for mobile game adoption. A questionnaire was developed built upon previous studies. A survey was then conducted, which received 267 useful responses. The results suggested that users perceive mobile game differently with regard to experience and gender difference. It is suggested that the users who have more computer...

Virtual reality technology has become a main research field of computer development application gradually in recent years. Virtual campus is a specific application of virtual reality technology in the digital campus. The basic principles and key technologies of building virtual campus model are studied in this paper. According to the requirements of virtual reality, virtual campus 3D models are established,...
Nowadays, college English teaching and learning is attached greater and greater importance. In 2004 and in 2007, the Ministry of Education issued "College English Curriculum Requirements" respectively. Both versions emphasize the importance of applying modern information technology into college English teaching and more attention is paid to students' main position and teachers' leading role...
To model a high-resolution 3D human body model based on a set of image is a challenge work. In this paper, we present the 3D human body model reconstructed technique based on a generic model deformation method and a color texture standardization technique. Firstly a set feature points on images and their corresponding character vertices on generic model are defined. Then a customized model is yielded...
In this paper, a novel 3D face modeling approach from monocular video is proposed. The core of the approach is to deform the generic face model based on the facial feature information extracted from video frames in order to reconstruct a specific 3D face model. The approach composed of following steps: marking facial feature points for the first video frame, and extracting face contour at the beginning,...
In this paper, we introduce an Intrusion Detection system (IDS) based Hybrid Evolutionary Neural Network (HENN). A brief overview of IDS, genetic algorithm, and related detection techniques are discussed. The system architecture is also introduced. Factors affecting the genetic algorithm are addressed in detail. Unlike other implementations of IDS, Input features, network structure and connection...
The characteristic of water transport and loss in a direct-seeded paddy field, Danyang Region at upstream of Taihu Lake Basin, was studied under local traditional field water management using Hydrus-1D model. Results show that the drying/wetting boundary condition on soil surface was well simulated by using divided stress period method in the Hydrus-1D model, and the estimated hydrodynamic parameters...
Network virtualization provides the feasibility of running multiple routing architectures on a shared physical infrastructure. This paper presents the design and evaluation of a bandwidth management algorithm which is based on traffic predictor. We generated the simulation traffic with the ARMAX/GARCH model. The basic idea of our design is that some failure in the MFP computation implies that one...
The report has presented an OPNET simulation model for the Ad-hoc on demand Distance Vector routing protocol. During the process of validation, this implementation of the AODV protocol is supplied with a hierarchical structure of models consisting of a simulation model, a network model, a node model, and finally a set of process models. All the conclusions are helpful to further development and optimize...
The application of virtual reality technology is a trend that holds considerable promise as demonstrated in many applications. This technology includes the means to visually integrate and interact with diverse multidimensional data in 3D and time context, extend real-time decision-making into mine maintenance, implement virtual mine-planning simulations, training simulations, and risk management....
Considering the utility of nodes in distributed environment, a resource allocation method based on comparative advantage is presented, which achieves maximum system efficiency by making global equilibrium. Different from the neoclassical economics theory, the new classical economics theory achieve Pareto Optimality by tuning the allocation policy dynamically with the division of labor theory. Simulation...

Based on the analysis of complex products co-simulation features, functions and modeling on the basis of the process, based on the HLA/WE_RTI co-simulation of complex product platform and its architecture, Based on a simulation of product integration modeling, simulation...
The workflow plays an important role in improving the enterprise production efficiency of management, the information automation and the competitiveness. Simultaneously the workflow as an efficient integrated method can be applied in many kinds of domain. The related concepts of Petri nets and workflow modeling standards are introduced in the paper, including four kinds of basic structure: sequence,...
Visual Simulation, which has been applied widely to provide convenience to people from every walk of life, plays a crucial role in the field of Virtual Reality. In this thesis, 8 models representing 8 typical materials, are created by MultiGen Creator, and rendered by Vega for analysis of relation between grey values in simulated pictures and real radiance. Finally, the method of infrared simulation...
This paper presented incremental support vector data description (ISVDD) method and used it to detect anomalies in hyperspectral images. Anomaly detection is essentially a problem of one-class classification, a good solution of which is SVDD, using optimized minimal hypersphere to express tightly the background and using distinguish function to detect anomalous pixels. The method avoided the problem...
It is generally a few hundred to several thousand kilometers of long distance oil pipeline, and modern oil pipeline often adopt the close-line oil transportation, so the whole pipeline is a unified set of hydraulic system. Once the disturbance occurs in somewhere along the line, which will sweep the whole line, and propagation velocity is much faster than manual response capability making a high demand...
