Emerging Technologies for Electric Power Generation Personnel Training
Considering that the trend in the workers’ training is the personalization and the use of technologies for self-learning; this article examines the role of emerging technologies and methodologies in the future of training of electric energy production human resources of Comisión Federal de Electricidad. We analyze the problem of complexity as an ingredient inherent in the activities of operation and maintenance of equipment for electricity generation.
Emerging Technologies for Learning Science: A Time of Rapid Advances
In February, 2007, we co-edited a special issue (Vol. 16, No. 1) that focused on technologies for learning science that are inquiry-based, leverage multiple media, and inte grate game-design principles and scenarios to establish rich inquiry-based contexts for engaging scientific issues. Since that time, we have prepared a second special issue on emerging technologies, this time with a somewhat broader focus on new technology-based methods of learning sci ence. As a field, we are in an era of very rapid advances in interactive media, and the seven articles in this issue span pedagogies based on Web 2.0 tools, immersive interfaces, and games. The term Web 2.0 reflects a shift in leading-edge applications on the World Wide Web from the presentation of material by website providers to the active co-con struction of resources by communities of contributors (Dede 2008a). Whereas the twentieth-century web centered on developer-created material (e.g., informational web sites) generated primarily by a small fraction of the Inter net's users, Web 2.0 tools (e.g., Wikipedia) help large numbers of people build online communities for creativity, collaboration, and sharing. As part of a graduate course this past fall on emerging educational technologies, Dede's students studied ten forms of Web 2.0 tools in terms of their potential to enhance learning by promoting creativity, collaboration, and sharing. Retrospectively, he categorized these media
Numerical Simulation of Induction Heating Process of Continuous Casting Slab
Compared with traditional blazing furnace, the Continuous Casting-Direct Rolling is an advanced manufacturing steel technology, which can reduce energy waste, decrease pollution and enhance efficiency. The characteristics of steels during induction heating are complex, the change of material properties with temperature makes exact analysis methods very difficult to implement. Therefore, a powerful computer aided numerical tool (i.e., finite difference analysis) is selected to numerically model the induction heating process in this paper. The mathematic model coupling with electromagnetic field and thermal field was established, and it was solved by finite difference method (FDM), thus the slab temperature distribution and its variation with time were obtained, and the characteristics in whole induction heating process were studied. To validate the program feasible, the results were evaluated and compared with experiment results, which showed that the simulation results are reliable and effective. The skin effect in heating process from the two results was studied and demonstrated, the temperature change caused by different parameters such as the induced power intensity and the corner radian were also presented, which indicate that the slab temperature can be heated uniformly through adjusting these parameters, thus the continuous casting slab can meet the rolling requirement.
