In this article, a multi-port non-isolated converter is implemented for renewable energy applications. High voltage gain accomplished with switched capacitor and coupled inductor, power transfer between the inputs, battery, load can be realized using three switches. The collected in leakage inductance reused to decrease stress on switch. Various functioning periods are also examined, design req...

Myrinet is a new type of local-area network (LAN) based on the technology used for packet communication and switching within "massivelyparallel processors" (MPPs). Think of Myrinet as an MPP message-passing network that can span campus dimensions, rather than as a wide-area telecommunications network that is operating in close quarters. The technical steps toward making Myrinet a reality includ...

We have taken a Grand Challenge 3d Multi-Grid code, QGMG, initially developed on the Cray C-90 and subsequently parallelized for MPPs, and implemented it using the DUDE object-oriented, runtime system which combines both task and data parallelism. The QGMG code is a challenging application for two reasons. Firstly, as in all multigrid solvers, the morrt straightforward implementation requires t...

To investigate hydrodynamic processes above and within river beds, laboratory experiments have been performed to quantify the interaction between turbulent flow and pressure fluctuations at a porous gravel bed. A 2-D Particle Image Velocimetry (PIV) system measuring in streamwise vertical or horizontal planes above the gravel layer was used, synchronized with a pressure sensor array of 16 minia...

It is difficult for a photovoltaic system to execute at maximum power since ambient temperature and solar irradiation are not constant. The performance of (PV) array nonlinear. the features under partial shading (PS) includes various local point (MPPs) one global. Hereafter, it’s task follow global (GMPP) conditions (PSC). To reach an optimal should use MPPT (maximum tracking) controller as wel...

Parallel iterative solvers are often the only means of solving large linear systems and eigenproblems. However, these solvers are usually implemented in a fine grain manner and, when scaled to large numbers of processors on MPP’s, can incur significant performance penalties due to synchronization overheads. This problem is exacerbated in clusters of workstations (COWs) and SMPs that are interco...

Turbulence reduction via sheared plasma flow (A), compared to case with flow suppressed (B). Results obtained using full MPP capabilities Fusion is the power source of the sun and other stars. It occurs when forms of the lightest atom, hydrogen, combine to make helium in a very hot (100 million degrees centigrade) ionized gas or " plasma. " In this process a small amount of the matter involved ...

Computer simulations are used to create and evaluate real world scenarios in a manner that is controlled, nonintrusive, cost effective and safe. One technology for realising computer simulation is Multi Agent Based Simulation (MABS), the advantage being that the entities that feature in a simulation can be expressed as agents that have all the features associated with agents (autonomy, goal dri...

We propose, and justify, an economic theory to guide memory system design, operation, and analysis. Our theory treats memory random-access latency, and its cost per installed megabyte, as fundamentals. We introduce incentives in our economic theory, and side-constraints in our analytic model of hierarchical memory, to ensure su cient memory bandwidth and processor speed in any \well-formed" sys...
