The Cell BE architecture consists of a 64-bit Power-compliant Processing Element (PPE) and eight Synergistic Processing Elements (SPEs), loosely coupled through a coherent memory sub-system. Through their programmability, the SPEs provide computational density advantage over conventional processors while still providing greater flexibility than traditional fixed function ASICs. The SPEs' instru...

In this work, the rectangular nonconforming Wilson element in solving incompress-ible elastic equation is analyzed. Although the element does not satisses the inf-sup condition (in a mixed formulation), it still can be used to compute the displacement successfully. If a simple post-processing is applied, the pressure converges, too. An optimal convergence rate is established for both displaceme...

A method for post-processing the velocity after a pressure projection is developed that helps to maintain stability in an under-resolved, inviscid, discontinuous element-based simulation for use in environmental fluid mechanics process studies. The post-processing method is needed because of spurious divergence growth at element interfaces due to the discontinuous nature of the discretization u...

Rolling element linear motion bearings are widely used to guide, support, locate, and accurately move machinery components and products in a wide range of automation applications. Rolling element linear bearings and guides provide low friction, smooth, accurate motion for nearly any moment or normal loading condition. Major applications include factory automation, medical, packaging, machine to...

in this study, displacement field around v-notches of a poly methyl metha crylate (pmma) specimen with tip cracks will be analyzed using digital image correlation technique. first intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...

We present a systematic method for developing low order nonlinear models from physically based, large scale finite element models of rapid thermal processing (RTP) systems. These low order models are extracted from transient results of a detailed finite element model using the proper orthogonal decomposition (POD) method. Eigenfunctions obtained from the POD method are then used as basis functi...

The notion of element-connectivity has found several important applications in network design and routing problems. We focus on a reduction step that preserves the element-connectivity [18,4,3], which when applied repeatedly allows one to reduce the original graph to a simpler one. This pre-processing step is a crucial ingredient in several applications. In this paper we revisit this reduction ...

We consider the problem of approximating the maximum of the sum of m Lipschitz continuous functions. The values of each function are assumed to reside at a di erent memory element. A single processing element is designated to approximate the value of the maximum of the sum of these functions by adopting a certain protocol. Under certain assumptions on the class of permissible protocols, we obta...

Video object segmentation is an important pre-processing task for many video analysis systems. To achieve the requirement of real-time video analysis, hardware acceleration is required. In this paper, after analyzing existing video object segmentation algorithms, it is found that most of the core operations can be implemented with simple morphology operations. Therefore, with the concepts of mo...

The finite element method (FEM) has established itself as a powerful tool in biomechanics. However, developing a finite element three dimensional mesh for irregular geometry object is still a labor intensive task hence limits the usage of the three dimensional analysis for dental structures. This study presented an automatic procedure to generate the three dimensional finite element mesh of a m...
