This paper presents the modeling and simulation of a proton exchange membrane fuel cell (PEMFC) generation system for off-grid and on-grid operation and configuration. A fuel cell DG system consists of a fuel cell power plant, a DC/DC converter and a DC/AC inverter. The dynamic model for fuel cell array and its power electronic interfacing are presented also a multi-input single output (MISO) D...

It is shown that every orthogonal terrain, i.e., an orthogonal (rightangled) polyhedron based on a rectangle that meets every vertical line in a segment, has a grid unfolding: its surface may be unfolded to a single non-overlapping piece by cutting along grid edges defined by coordinate planes through every vertex.

Multi–grid back–projection (MGBP) is a fully–convolutional network architecture that can learn to restore images and videos with upscaling artifacts. Using the same strategy of multi–grid partial differential equation (PDE) solvers this multiscale scales computational complexity efficiently increasing output resolutions. The basic processing block inspired in iterative (IBP) algorithm constitut...

Color image denoising is frequently encountered in various processing and computer vision tasks. One traditional strategy to convert the RGB a less correlated color space denoise each channel of new separately. However, such can not fully exploit information between channels inadequate obtain satisfactory results. To address this issue, paper proposes multi-channel optimization model for under ...

The fluid–structure interaction of cylinders in tandem arrangement is used as validation basis a multi-domain Lagrangian–Eulerian hybrid flow solver. solver built on Lagrangian approximation the entire flow-field using particles, which grid based Eulerian solutions are overlaid, one for every solid body. grids body fitted but limited width and may overlap cases close proximity bodies. strongly ...

Many Grid portal architectures have three layers: browser, portal and Grid environment. We design a multi-layer Grid portal architecture, which introduced Mobile Agent; the mobile agents can gain the different information of the Grid resources. This paper analyzes the multi-layer architecture of Grid portal, presents the security strategy and introduces the function of different mobile agent.

We assess the performance of hybrid Open Accelerator (OpenACC) and Message Passing Interface (MPI) approach for multi-graphics processing units (GPUs) accelerated thermal lattice Boltzmann (LB) simulation. The OpenACC accelerates computation on a single GPU, MPI synchronizes information between multiple GPUs. With two-dimension (2D) simulation achieved 1.93 billion updates per second (GLUPS) wi...

In the field of conservation biology, accurate population models are important for managing wildlife. It has been acknowledged that spatial structure should form an integral part of such models. Advancement in the power of desktop computers has allowed biologists to construct individual-based, spatially-explicit simulation models to predict the population dynamics of species. These models take ...
