computer games are more and more popular and have grown to be a large industry, but game talents are lack and training mechanism is not yet perfect in our country. In order to solve this problem, it is necessary to develop game courses or specialty in domestic universities. In this paper, we analyze ways for integrating games into computer science curricula in several world-famous universities whose experience can be used for reference to us. With the guidance, some advices and conceptions are given for developing games in domestic universities, taking Beihang University as an example.

We describe the initial concept for a computer-assisted instruction strategy that can be developed to improve the current state of learning in the classroom of the following two topics in geoscience education: (1) stochastic theory in hydrologic sciences;and (2) the role of hydrologic process controls in satellite-based monitoring of flooding. Our scheme is founded on a spacetime stochastic model to generate precipitation distributions from satellite data and a user-friendly Graphical User Interface (GUI) that connects the stochastic model to hydrologic modeling tools. The stochastic model, being rich in application of wide ranging concepts of stochastic theory, is considered an ideal medium to translate stochastic theory to problems on modeling variability of systems that may arise in a student's future professional work. The GUI will provide full interactive control to students to couple the stochastic model with hydrological models of varying levels of complexity and observe independently the corresponding streamflow simulation graphically. An existing Modular Modeling System (MMS) developed by the United States Geological Survey (USGS) is selected as the main educational software architecture for this purpose. Through our proposed end-to-end graphics-based instruction system, students are expected to learn more effectively the following: (1) the implications of applying alternative stochastic theories on the simulation end-product (i.e., stream-flow from hydrologic models driven by satellite rainfall data);(2) the importance of various hydrologic process controls on flood phenomena;and finally (3) relevance of the various assumptions embedded in application of stochastic theory to real-world problems and the corresponding influence on modeling variability that students may encounter in their future professional work.

This paper presents two novel smart cross-layer error-control coding schemes for improving the error protection of service advertisements that are broadcast to mobile terminals on wireless billboard channels (WBCs) established over a digital video broadcast-handheld (DVB-H) infrastructure. These are the smart section erasure (SSE) and smart transport stream erasure (STSE) schemes, which are jointly executed by the link layer and service layer cross-layer algorithms. The new schemes are analysed and compared to existing schemes. The solution enables the "WBC over DVB-H" system to operate with good flexibility, and in a more reliable way and with greater throughput efficiency than the standard IP datacasting supported in DVB-H.

The level of programming experience demanded from the graduates of ICT studies increases continuously and therefore new subjects have been added to the curricula of ICT studies at the Faculty of Informatics and Management, University of Hradec Kralove during several last years. computer graphics is one of the most important subjects added The article describes how the computer graphics subjects could be taught to help students spread and deepen their programming knowledge and skills.

A 3D visualization environment contains domain information about geologic features in seismic data and lets users interactively steer segmentations on the basis of visual sources of information and knowledge. A user study demonstrates this approach's ability to transfer domain knowledge to nonexperts.

In a virtual environment (VE), efficient techniques are often needed to economize on rendering computation without compromising the information transmitted. The reported experiments devise a functional fidelity metric by exploiting research on memory schemata. According to the proposed measure, similar information would be transmitted across synthetic and real-world scenes depicting a specific schema. This would ultimately indicate which areas in a VE could be rendered in lower quality without affecting information uptake. We examine whether computationally more expensive scenes of greater visual fidelity affect memory performance after exposure to immersive VEs, or whether they are merely more aesthetically pleasing than their diminished visual quality counterparts. Results indicate that memory schemata function in VEs similar to real-world environments. "High-level" visual cognition related to late visual processing is unaffected by ubiquitous graphics manipulations such as polygon count and depth of shadow rendering;"normal" cognition operates as long as the scenes look acceptably realistic. However, when the overall realism of the scene is greatly reduced, such as in wireframe, then visual cognition becomes abnormal. Effects that distinguish schema-consistent from schema-inconsistent objects change because the whole scene now looks incongruent. We have shown that this effect is not due to a failure of basic recognition.
