In recent years, e-learning has become a popular method of learning. Generally, an e-learning platform which provided multi-media content required a high capacity storage device such as NAS (network attached storage) or SAN (storage area network). However, many schools with insufficient budgets cannot afford this type of expensive equipment. Thus, we employ grid computing and PVFS (parallel virtual file system) technology to integrate the idling storage resources in the school as a means to substitute the purchase of an expensive high-level storage server. In this research we will link several sets of PCs in the school to make them armed with the storage and computing capacity like that of a high-end server. We hope the goal of sharing and reuse of resources among the schools can be achieved.

Over the past decade, speed in the transmission of knowledge is no longer the way it used to be. Due to this influence, conventional educational methodology has also followed this trend and has gone through a momentous transformation. An excellent example is e-learning which has achieved and broken through the restrictions of time and space. In recent years it has become one of the most popular teaching methods. SCORM (Sharable Course Object Reference Model) the most popular e-learning standard has been adapted from many differing e-learning platforms. Normally, courseware meeting SCORM standards is sharable with other e-learning platforms. Most e-learning platforms however are unable to share courseware directly on the Internet. With this in mind, we have employed one type of grid computing technology called "data grid" in order to achieve this. This technology allows the integration of different SCORM platforms into a huge e-learning environment.

In this paper, we introduce our experiments on SLIM and DRBL diskless PC clusters. We constructed them by using 16 machines and only one disk. We run the matrix multiplication and bioinformatics software to evaluate their performance. We find that the performance of SLIM has a great improvement, and the system setup time is much less than before. The network loading of DRBL is also very high. The system boot-up time is no difference between these two systems. The best way to construct the diskless Linux cluster is to eliminate the image size. It can make the nodes have more memory space to handle the program and ease the network loading.

In this paper, we evaluate the performance of Meghadoot - a packet based wireless mesh network architecture for low cost rural community networks. Meghadoot is designed for rural community networks as an alternative for the single-hop last mile. We have built a prototype network for the Meghadoot architecture and studied the impact of multi-hop relaying and constrained devices on end-to-end throughput. The experimental results show that in certain situations multi-hop last mile improves performance in addition to the enhanced coverage and also the presence of constrained nodes brings down the performance drastically.
We present a new technique for noninvasively tracing brain white matter fiber tracts using diffusion tensor magnetic resonance imaging (DT-MRI). This technique is based on performing diffusion simulations over a serie...

In the present study, THUBioGrid, an experimental distributed computing application for bioinformatics (BioGrid) is proposed. THUBioGrid incorporates directory services (data and software), grid computing methods (security, authentication, data transport and remote jobs), and gene sequence/genomic data processing methods. It uses Java CoG Kit plus bioinformatics Java packages to perform various computational tasks. The performance of THUBioGrid has been tested by executing the FASTA and mpiBLAST programs for protein sequence alignment applications. Results demonstrate the speed-up effects with increasing number of processors used in the computations.
