In this paper, work has been performed to recognize Handwritten English Character using a multilayer perceptron with one hidden layer. The feature extracted from the handwritten character is Boundary tracing along with Fourier Descriptor. Character is identified by analyzing its shape and comparing its features that distinguishes each character. Also an analysis was carried out to determine the...

Numerical analysis of open channel ̄ows has largely con®ned to using ®xed boundaries in the numerical codes. Given the size of the problem domain, using ®xed boundaries often taxes the computational resources since the e€ect of the boundary is transferred on to its adjacent node in the ®rst few iterations. In this work, we explore the performance of a moving boundary in conjunction with central...

The well-known complex variable boundary element method (CVBEM) is extended for using collocation points not located at the usual boundary nodal point locations. In this work, several advancements to the implementation of the CVBEM are presented. The first advancement is enabling the CVBEM nodes to vary in location, impacting the modeling accuracy depending on chosen node locations. A second ad...

Searching spatial data is an important operation for scientific simulations which are performed mostly with periodic boundary conditions. An R-Tree is a well known tree data structure used to contain spatial objects and it is capable of answering to spatial searching queries in an efficient way. In this paper, a novel method to construct an R-Tree considering periodic boundary conditions is pre...

This paper is concerned with the boundary particle method (BPM), a new boundary-only radial basis function collocation schemes. The method is developed based on the multiple reciprocity principle and applying either high-order nonsingular general solutions or singular fundamental solutions as the radial basis function. Like the multiple reciprocity BEM (MR-BEM), the BPM does not require any inn...

Matching the results obtained from circuit simulation with those extracted from circuit functioning is a common stage of the final verification process. Many current verification techniques use the I/O vectors produced during functional and / or timing simulation, for creating the test vectors to be applied / compared against the circuit responses. Techniques that are more complete include extr...

Hardware development of cryptographic algorithms is subject to various attacks. It has been previously demonstrated that scan chains introduce for hardware testability open a back door to potential attacks. Scan based testing is one of the mainly used and powerful test technique since it provides full observability and controllability of the internal nodes of the IC. It has been previously demo...

The parallel performance and efficiency of boundary element methods in the solution of inelastic problems are investigated. A parallel algorithm based on the so-called initial stress scheme for inelastic analysis is developed and implemented in BEMGEO (Boundary Element Method program for GEOmechanics applications). Numerical examples solved on an SP2 of 34 thin nodes are presented which highlig...

schwannomas are benign nerve sheath tumors that originate from any anatomical site. most of the schwannomas are found in the head, neck or limbs. schwannoma arising in a lymph node is extremely rare. we have found only four cases in the review of the literature. we experienced a case of intranodal schwannoma in a perigastric lymph node. a 72 year-old female underwent cholecystectomy due to clin...
