A lightweight interface to local grid scheduling systems
… such problems, the concept of the computational Grid was conceived. Although Grid technology is hailed as the next great enabling technology in Computer Science, the last being the inception of the World Wide Web, some concerns have to be addressed if this technology is going to be successful. …

Adaptive Finite Element Methods for Rigid Particulate Flow Problems
… In this context, special emphasis is given to local grid adaptation. The goal is to obtain a high accuracy and, at the same time, to keep the computational effort as low as possible.

Local Factorization of Multidimensional Differential Operators to Optimize Implicit Solution Methods
… Using the factor calculated in this Affine Local Grid Factorization (ALG-F), it is possible to solve the system by simple back substitution followed by forward substitution resulting in an implicit scheme that is O(N) rather than O(N^2) typical in implicit finite-difference schemes. Included …

Geometry Projection Methods for Shape and Topology Optimization
… window whose diameter is proportional to the local grid spacing in the mesh used for response analysis. Thus, the errors associated with both the geometry projection and the response discretization vanish in the limit of mesh refinement. Accordingly, the numerical response solution converges …

Competitive Microgrid Electricity Market Design
The electric power grid forms the foundation for several other critical infrastructures of national importance such as public health, transportation and telecommunication systems, to thrive. The current power grid runs on the century-old technology and faces serious challenges of the 21st century - …

Application of r-Adaptation Techniques for Discretization Error Improvement in CFD
… error. Discretization error is introduced locally into the solution by truncation error. Truncation error represents the higher order terms in an infinite series which are truncated during the discretization of the continuous governing equations of a model. Discretization error can be …

SNAP-based grid resource broker using the three phase commit protocol
Grid computing is diverse and heterogeneous in nature, spanning across multiple domains where resources are not owned or managed by a single administration. This brings about many challenges to Grid resource management and exposes the user to the Grid middleware complexities. Thus this research …

Finite element analysis of flows in secondary settling tanks
… also possible to realise an unstructured grid within the FVM, the power of the finite element method (FEM) lies in its higher flexibility in fitting irregular domains and in providing local grid refinement. Generally, unstructured mesh procedures with the FVM require essential, additional …

Efficient finite-volume schemes for magnetohydrodynamic simulations in solar physics
… enhancement of the codes' efficiencies by using locally-adapted grids. We introduce a new limiter (DEOmod) for linear reconstructions on unstructured triangular grids in 2d that represents a clear improvement of the approaches commonly used. Simulations in physically-unbounded domains are enabled …

Improving electricity supply in the Indian state of Odisha using under-the-grid micro-grid technology
… and presence of wildlife activity that make the grid maintenance a complex affair, the DISCOMs incur into exceptionally higher O&M costs. The objective of this thesis is to study some issues that result in systematic economic losses in localized areas for Tata Power Odisha (TPO) who has recently …

A Management System for Service level Agreements in Grid based Systems
Grid based systems have increased the opportunity for users to deploy and execute their applications using Grid resources. These resources have varying reliability and performability, particularly when demand is high. If a Grid application is executed at such times, performance may suffer and …
