The support vector machine (SVM) shows many unique advantages in solving the small sample, nonlinear and high dimensional pattern recognition problems, and it is very suitable to solve the classification problem in motor imagery EEG. For SVM using radial basis function (RBF) kernel, two parameters had to be selected beforehand: the trade-off parameter C and the kernel parameter σ. The tradition...

Search engines require computers with high computation resources for processing to crawl web pages and huge data storage to store billions of pages collected from the World Wide Web after parsing and indexing these pages. The indexer is one of the main components of the search engine that come intermediate between the crawler and the searcher. Indexing is the process of organizing the collected...

there area lot of mobile computer devices with a variety of applications and users tend to use them more. due to the limitations of mobile devices, running most of the procedures are impossible. to resolve this problem, mobile devices can be connected to the grid, to use the facilities of grid. on the other hand the communication mechanisms are different for each device and they cannot be conne...

We present a flexible parallel implementation of the exhaustive grid search algorithm for multidimensional QTL mapping problems. A generic, parallel algorithm is presented and a two-level scheme is introduced for partitioning the work corresponding to the independent computational tasks in the algorithm. At the outer level, a static blockcyclic partitioning is used, and at the inner level a dyn...

The remit of the European DataGrid (EDG) [2] project was to develop an infrastructure that could support the intensive computational and data handling needs of widely distributed scientific communities. An important part of managing the data present in such a Grid is file replication placing copies of files at different sites in order to reduce data access times, hence shortening job running ti...

There have been recent proposals in search of alternative security architectures to PKIs for grid application and e-Science. The application of identity-based cryptography (IBC) in designing a grid security architecture seems to be interesting because of its attractive properties, such as, being certificate-free and having small key sizes. In this paper, we discuss our latest research findings ...

Using semantic technologies in grid-systems is considered. We propose the agent-based semantic information service for grid-resource discovery. Ontology is a good approach to resource discovery by providing a formal conceptualization of a grid-system. The approach suggested in the paper allows mapping the elements of ontological languages to the semantic service knowledge base relying on the fi...
