A homology and cohomology solver for finite element meshes is represented. It is an integrated part of the finite element mesh generator Gmsh. We demonstrate the exploitation of the cohomology computation results in a finite element solver, and use an induction heating problem as a working example. The homology and cohomology solver makes the use of a vectorscalar potential formulation straight...

The objective of this paper is to develop a hierarchical model of a systolic array which solves differential equations by using Upgraded Petri Net (UPN). The Upgraded Petri Net presents a formal modeling tool, based on mathematical apparatus, used for simulation and analysis of processes, particularly at the register transfer level. Original software for modeling and simulations of Upgraded Pet...

High speed message handling is one of the most important problems for e cient multithread processing. We have proposed a processor architecture called DatarolII, that promotes the e cient ne-grain multithreaded execution, by performing fast context switching among ne-grain concurrent processes. We are developing a prototype multithread machine KUMP/D (Kyushu University Multi-media Processor on ...

Three eye movement experiments investigated the interaction between contextual and lexical focus cues during reading. Context was used to focus on either the indirect or direct object of a double object construction, which was followed by a remnant continuation that formed either a congruous or incongruous contrast with the contextually-focused object. Experiment 1 demonstrated that remnants we...

1. INTRODUCTION Integrated optical devices such as surface emitting laser array, photo detector array and OEICs promise high performance parallel processing. Although these devices have two-dimensional paral-lelism for pattern information processing, their potential capabilities are not utilized in conventional parallel processing systems. The " I/O bottleneck " between processing element (PE) ...

taknar deposit is located about 28 km to the north-west of bardaskan in the khorasan-e-razavi province, which is situated in the north-eastern part of iran. this deposit is unique, formed within the taknar formation in the ordovician time. as a result, it is of much interest to many researchers working in this field. by choosing the lithogeochemical study performed to recognize new exploration ...

The expression of two mitochondrial gene clusters (orf87-nad3-nad1/A and orf87-nad3-rps12) was studied in Nicotiana sylvestris. 5' and 3' termini of transcripts were mapped by primer extension and nuclease S1 protection. Processing and transcription initiation sites were differentiated by in vitro phosphorylation and capping experiments. A transcription initiation site, present in both gene clu...

Laser Shock Processing (LSP) is an innovative surface treatment technology. LSP can induce compress residual stress layer in the surface of metallic materials, which is used for improving the fatigue life. In this study, the propagation course of typical laser shock wave in material was analyzed according to the theory of plasticity dynamics and the theory of stress wave. The effects of laser s...

In this paper, we present three parallel algorithms for matrix multiplication. The rst one, which employs pipelining techniques on a mesh grid, uses only one copy of data matrices. The second one uses multiple copies of data matrices also on a mesh grid. Although data communication operations of the second algorithm are reduced, the requirement of local data memory for each processing element i...
