In this paper we describe changes in a subject of digital logic design to fit the new plan of Bologna. The subject has a significant increase in hours of laboratory and students compared to previous years. We present the results of a student satisfaction survey and a comparison of the success of overcoming the remaining subject compared to past years.
This paper researches on the real time subdivision of surface rendering using approximation scheme and focuses on two methods — Catmull-Clark and Loop subdivision. The two methods are commonly employed separately in many existing applications and graphics engine. Catmull-Clark outperforms on quad meshes and Loop subdivision superiors on triangle meshes. The exchange of the meshes produces ugly polygonal...
The critical technology, common problems and feasible resolution of virtual maintenance are studied in this article. Applying these theories, a virtual maintenance system is developed. By using the system, the efficiency of maintenance and training is greatly improved.
First, this paper introduces the four tiers architecture of Team center, the integration framework for CAD/CAPP/PDM, and gives the integrated method of each system based on Team center. Second, this paper concretely analyzes the technological design process based on the PDM. Then based on a bearing company's normalization project, we introduce the enterprise's business data model, the establishment...
Having left the TWT industry in the mid 1990's after a 15 year career as a Vacuum Tube Engineer this paper looks back at what changes have occurred and where the industry is headed in the future. As technology continues to advance giving us smaller, faster and more powerful computers has the vacuum tube industry kept up or have we simply increased frequency and power levels without necessarily advancing...
The purpose of this research is to build a real-time flight simulator for quadrotor systems and verify if the simulator runs in real time. The simulator was constructed by writing the mathematical models of quadrotor dynamic in MATLAB/Simulink. Using xPC Target software environment, three PCs were set up to work in sync to make the simulation run in real time. This paper shows several simulation results...
Sand models as used in military are thematic 3D representations of an area of interest which combined the information of maps with a more realistic 3D bird's eye view of the terrain. Sand models have been used for military planning and war gaming for many years as a field expedient, small-scale map, for planning and training of military operations. This, however increasingly fell out of favor with...
The purpose of this research was to introduce a computer environmental assessment tool into computer aided product design. A new computer tool “CFE (Carbon Footprint Evaluator)” was developed due to the “Carbon Emission” issue. The proposed tool can assist a designer to monitor his new developing parts or products. The designer can directly obtain the carbon footprint information of a part or a product...
This paper presents the general structure and implementation features of the original complex software for command and control of the anthropomorphic gripper for robots. The software has three modules: RoboVISION, RoboSIM and RoboCOMMANDER. RoboVISION is a software module for tracing, visualization, shape recognition, measurement, and efficiency evaluation for 3D model generation of objects to grip...
Research has demonstrated that people learn best when they are actively involved in the learning process. Games and simulations are especially effective as discovery learning approaches since they pull learners into the learning experience in interesting, fun and challenging ways. This article seeks to demonstrate the effective use of simulation and gaming technique in providing an engaging and high-energy...
In this paper, we propose a cybernetics-based model of forces that integrates personality within it, called GSCP, which can well simulate how the psychological factors impact on the behaviors of entities. The modeling is achieved by introducing a genotype sequence to embed personality of entities into behavior decision-making. In order to decide the next behavior, a decision-making mechanism called...
Using 3D computer simulations for training surgeons is not new, but neither is the use of e-learning for improving students knowledge acquisition. What we propose is to use 3D computer simulations in such a versatile way that those simulations could act as learning objects designed directly by those who own the experience we want to be transmitted. In order to achieve this goal, it is necessary to...
Based on the virtual realistic technical, the text discussed the feasibility of the virtual realistic technique can be applied to tour system constructive. Finally, on the foundation of the Earth platen, inquired the feasibility and key technique of virtual realistic technique in the travels system tapping.
Introduce the research contents of computer graphics research, development history, composition and function of the graphics system, applications and implementation of realistic graphics technology, generalize the graphics basic content, in order to better grasp the computer graphics and image processing technology.
Important visual features in current mesh simplification was easily lost, which thus often caused distortion of vision. In order to get simplified models with high fidelity, this paper proposes an improved edge-collapse mesh simplification algorithm by introducing Gauss curvature to QEM algorithm. The experimental results show that the approximations simplified by our algorithm maintain higher fidelity...
this paper proposes a algorithm to generate the panoramic view from 360 ¡ãfisheye images based on angular fisheye projection model. Firstly, the image plane will be mapped to the view plane, the sphere plane, to obtain the coordinates of spherical points. Then use the angular fisheye projection model to get fisheye images' radius. Secondly, calculate the coordinates of fisheye images' points with...
Building information technology includes production process information technology and management information technology. The first one can improve efficiency and productivity, and the other one can improve the business treatment efficiency and management level. In this paper, combining with the application requirement of building construction, application research o virtual simulation technology...
The article presents a software tool that provides an easy way to creates augmented reality presentations. This tool allows the user to authoring his own presentation without a help of a programmer. The tool is supported by a web portal that provides the account creation and a database to storage the presentations created by the users.
In this paper, we propose a method for resource recommendation based on topic model in an e-learning system. The Web provides an extremely large and dynamic source of information. So it is now increasingly popular to provide personalized service in document recommendation. Personalized service can reduce information overload and, hence, increase user satisfaction. Topic model is a generative model...
Morphing IFS fractal is a significant way to create new fractal mode ls. Many works have exploited this issue for various purposes, but without considering the appearance of fractal feature degeneration during the morphing procedure between two IFSs. In this paper, by calculating local attractor's coarse convex-hull and selecting rotative matching between IFSs, we design a new IFS correspondence method...
