The power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. This paper presents modeling and optimization of a photovoltaic (PV)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in Rafsanjan, Iran. For this location, different hybrid systems are studied and ...

This paper proposes a simple and scalable web-based model for grid resource discovery for the Internet. The resource discovery model contains the metadata and resource finder web services. The information of resource finder web services is kept in the repositories that are distributed in the application layer of Internet. The resource finder web services will be discovered by sending queries to...

In the era of huge datasets, the topsearch becomes an effective way to decrease the search time of topobjects. Since we suppose locally accessible data only, the multidimensional indexes containing all attributes together seem to be more effective than a distribution of each attribute to a separate index. Therefore we introduce the topsearch algorithm over grid file – the multidimensional index...

Distributed Aircraft maintenance Environment (DAME) is a major UK eScience Grid project aiming to build a Grid test-bed for Distributed Diagnostics. The main challenge of the DAME project is the design and implementation of a fault diagnosis and prognosis system over the Grid computing infrastructure. This paper examines how the Grid may effect the implementation of search engines by focusing o...

In this paper, we present CoMRI, Compressed MultiResolution Index, our system for fast sequence similarity search in DNA sequence databases. We employ Virtual Bounding Rectangle (VBR) concept to build a compressed, grid style index structure. An advantage of grid format over trees is subsequence location information is given by the order of corresponding VBR in the VBR list. Taking advantage of...

inverse problem is one of the most important problems in geophysics as model parameters can be estimated from the measured data directly using inverse techniques. in this paper, applying different inverse methods on integration of s-wave and gpr velocities are investigated for estimation of porosity and water saturation. a combination of linear and nonlinear inverse problems are solved. linear ...

Some classical solutions to problems achieve particular speed ups when we allow those algorithms to become quantum based. The most obvious result is the ability to search a group of n elements in sub linear time. Classically, it is required to look at all of the elements, one at a time, to ensure that the marked item is or is not present. In the quantum world, thanks to Lov Grover [4], we can d...

The decoding parameters in automatic speech recognition — grammar factor and word insertion penalty — are usually determined by performing a grid search on a development set. Recently, we cast their estimation as a convex optimization problem, and proposed a solution using an iterative linear programming algorithm. However, the solution depends on how well the development data set matches with ...

This work describes application of local search based algorithms for job scheduling in the Grid environment where dynamic changes occur. The primary intent is to consider problems with the typical quality of service constraint taking into account and minimizing the number of late jobs. To achieve this goal a special instance of the Tabu search algorithm applicable to dynamic problems is propose...

A novel genetic algorithm called GGA (Grid-based Genetic Algorithm) is presented to improve the optimization of multimodal real functions. The search space is discretized using a grid, making the search process more efficient and faster. An integer-real vector codes the genotype and a GA is used for evolving the population. The integer part allows us to explore the search space and the real par...
