E -learning, the newly introduced concept has dramatically changed the previous style of learning and made learning material within the reach of the common pupils aspiring higher education. Contextually, the websites of distance learning in India with special reference to the state West Bengal need to be radically ultra modernized in such a way so that learning materials will be available to the students and more pupils w0ill pay attention and interest to go for this web enabled learning which will gradually enhance the Gross Enrollment Ratio (GER) of West Bengal. In our study a comparative analysis has been made among the distance learning web pages or websites of internationally reputed universities and the distance learning web pages or websites of the universities of West Bengal. Moreover the present GER of advanced countries along with West Bengal are taken. The correlation between the effectiveness of websites and GER is analyzed and necessary suggestions with comments are recommended to increase the effectiveness of the university distance learning websites in West Bengal.

Quality of content in e-learning is undoubtedly the key aspect to attract the students aspiring to go for higher education through e-learning. So, quality of e-learning content must be brief, precise, up to date and easily understandable so that it can be highly acceptable to the e-learning intended students. In this paper a model is anticipated with the objective to enhance the Gross Enrollment Ratio (GER) of West Bengal through establishment of e-learning in higher education. We provided an initial content of any subject matter and propose a scheme to upgrade the initially uploaded content up to a certain extent by using a graph theory based feedback method.

In this study, a mobile learning system is developed for a training program. With the assistance of the mobile learning system, the students are able to learn in an authentic learning scenario, in which they can physically face the target, with the personal guidance and supplementary materials from the learning system to support them. To show the effectiveness of this innovative approach, an experiment has been employed on the virtual university. The experimental results show that the innovative approach is helpful to students in improving their learning achievements. Moreover, it was found that most students showed favourable attitudes toward the usage of the mobile learning system and their participation in the training program.

Image registration using modified adaptive polar transform

Procedia computer Science 2010年 2卷 321-329页

作者： D. Sasikala R.

Image registration is of great significance to medicine and remote sensing, so a lot of techniques have been developed within the context of one or the other discipline. This paper proposes an approach for medical image registration using Modified Gabor Wavelet Transform (MGWT) for Modified Adaptive Polar Transform (MAPT). This algorithm can be used to register images of the same or different modalities. This transform analyzes periodic signal components and presents the advantage of being independent of the window length. The performance of the Modified Gabor Wavelet Transform is compared with previous methods like Log Polar Transform and Adaptive Polar Transform. The results show that MGWT outperforms all evaluated model-independent methods with respect to identification accuracy. These results show that the basis of errors produced by the previous methods is the fixed working scale. The new method not only avoids this basis of errors but also makes a tool available for detailed study.

International Conference on Power System Technology (POWERCON)

作者： A. Al-Hinai Assistant Professor at the Department of Electrical & Computer Engineering Sultan Qaboos University Muscat Sultanate of Oman

In this paper the dynamics of a single machine connected to infinite bus power system is analyzed. Such analysis requires a certain level of system modeling. The main system components models are the synchronous machine, excitation system and the Power System Stabilizer. The Matlab/Simulink is used as a programming tool to analyze the system performance. According to the system performance a proper design for the Power System Stabilizer (PSS) using Genetic Algorithm (GA) is carried out. Then the designed PSS is implemented in the model and the dynamic system response is analyzed. Since the simulation results without PSS showed unacceptable system response, the system response with the PSS has improved and the PSS succeeded to stabilize an unstable system. The designed PSS has been implemented in a microcontroller. Finally, the system response with PSS-microcontroller has been tested and compared with the simulation results.

To compare the performance of two speech coders, it is necessary to have some indicator of the intelligibility and quality of the speech produced by each coder. The term intelligibility usually refers to whether the output speech is easily understandable, while the term quality is an indicator of how natural the speech sounds. It is possible for a coder to produce highly intelligible speech from low quality, in that the speech may sound very machine-like and the speaker is not identifiable. On the other hand, it is unlikely that unintelligible speech would be called high quality, but there are situations in which perceptually pleasing speech does not have high intelligibility. In this paper the most common measures of speech enhancement models suited for speech recognition with specific emphasis on wavelet based approach are presented.

A Study towards Building An Optimal Graph Theory Based Model For The Design of Tourism Website

AIP Conference Proceedings 2010年第1期1298卷

作者： Goutam Panigrahi Anirban Das Kajla Basu Assistant Professor Department of Mathematics National Institute of Technology Durgapur Lecturer Department of Computer Applications Dr. B. C. Roy Engineering College Durgapur Associate Professor Department of Mathematics National Institute of Technology Durgapur

Effective tourism website is a key to attract tourists from different parts of the world. Here we identify the factors of improving the effectiveness of website by considering it as a graph, where web pages including homepage are the nodes and hyperlinks are the edges between the nodes. In this model, the design constraints for building a tourism website are taken into consideration. Our objectives are to build a framework of an effective tourism website providing adequate level of information, service and also to enable the users to reach to the desired page by spending minimal loading time. In this paper an information hierarchy specifying the upper limit of outgoing link of a page has also been proposed. Following the hierarchy, the web developer can prepare an effective tourism website. Here loading time depends on page size and network traffic. We have assumed network traffic as uniform and the loading time is directly proportional with page size. This approach is done by quantifying the link structure of a tourism website. In this approach we also propose a page size distribution pattern of a tourism website.
