Data-parallel languages like High Performance Fortran allow users to specify mappings of array by first aligning elements to an abstract Cartesian grid called templates and then distributing the templates across processors. Code generation then includes the generation of the sequence of local addresses accessed on a processor. Address sequence generation for non-unit alignment strides— referred...

A brief survey of some of the fundamental algorithms in unstructured mesh generation is presented. Included is a discussion and categorization of triangle, tetrahedral, quadrilateral and hexahedral mesh generation methods currently in use in academia and industry. Also included is a brief discussion of smoothing, cleanup and refinement algorithms. An informal survey of currently available mesh ...

The present paper deals with the invertibility of mappings that transform simply connected two-dimensional domains into a convex domain. The mapping is de ned by a system of second order elliptic equations. These mappings are used to generate so called structured grids in the physical domain to solve Computational Fluid Dynamics (CFD) problems. These grids are generated by mapping a uniform rec...

Abstract: We discuss basically the importance of reproduction number in Mathematical modeling as a summary measure of the transmission potential of an infectious disease.The basic reproduction number R0 for a compartmental disease model is often calculated by the next generation matrix (NGM) approach. It provides significant insight into the transmission dynamics of a disease and can guide stra...

This paper describes an algorithm for generating unstructured triangulations for arbitrarily shaped twodimensional regions. The algorithm works for regions without cracks, as well as for regions with one or multiple cracks. The algorithm incorporates aspects of well-known meshing procedures and includes some original steps. It includes an advancing front technique, which uses an quadtree proced...

Rapid advances in networking, hardware, and middleware technologies are facilitating the development and deployment of Grid applications, which are characterized by their very high computing and resource requirements. These applications and services have multiple, simultaneous end-to-end quality of service (QoS) requirements, such as delay guarantees, jitter guarantees, security, scalability, r...

The present scenario is towards shifting centralised power generation (central grid) to distributed generation (micro grid) with smaller sources of capacity. The isolated micro grid is connected to main grid with inverters at the front end for efficient exchange of power sharing; power exchange among distributed generation (DG) sources in an isolated micro grid is possible with droop characteri...

A scalable, parallel advancing grid generation technique has been developed for complex geometries and meshes with large size variations. The key innovation compared to previous techniques is the use of a domain-defining grid that has the same fine surface triangulation as the final mesh desired, but a much coarser interior mesh. In this way, the domain to be gridded is uniquely defined, overco...

In recent years, an ongoing increase of grid-connected distributed and renewable electricity generation technologies is clearly noticeable. From an environmental perspective, the increase of renewable technologies is highly desirable, as they do not emit greenhouse gasses and thus not contribute to climate change. Nevertheless, their increase poses increasing challenges on the reliable operatio...
