Domain decomposition methods are a major area of contemporary research in numerical analysis of partial diierential equations. They provide robust, parallel and scalable preconditioned iterative methods for the large linear systems arising when continuous problems are discretized by nite elements, nite diierences or spectral methods. This paper presents some numerical experiments on a distribut...

In Western thought and literature, a terrestrial bias is considered phenomenological primacy for notions such as wilderness. This ecocritical review draws on nineteenth-century South Seas literature with its influences from frontierism the literary movements of romanticism, realism naturism to consider more fluid appreciation reconceptualisation wilderness non-terrestrial an oceanic touchstone ...

The Color Purple written by Alice Walker is a powerful cultural touchstone of modern American literature to indicate large number symbolic images with profound meanings. paper analyzes the rich meanings contained in and metaphors, strives comprehensively interpret deeply understand themes ideological connotations novel. An interpretation indicates that: 1) embodied novel reflect Walker’s “overa...

This paper discusses the core factorization routines included in the ScaLAPACK library. These routines allow the factorization and solution of a dense system of linear equations via LU, QR, and Cholesky. They are implemented using a block cyclic data distribution, and are built using de facto standard kernels for matrix and vector operations (BLAS and its parallel counterpart PBLAS) and message...

While human-computer interaction (HCI) researchers invent a lot of interaction techniques that could improve usability of graphical applications, most of our interfaces are still based on the WIMPmodel (Windows, Icons, Menus and Pointing). The difficulty of assessing the performance of an interaction technique in a real context of use can partly explain this gap. This article aims at improving ...

In this note we describe the results of some tests of the message-passing performance of the Intel Paragon. These tests have been carried out under both the Intel-supplied OSF/1 operating system with an NX library, and also under an operating system called SUNMOS (Sandia UNM Operating System). For comparison with the previous generation of Intel machines, we have also included the results on th...

While current studies on Web services composition are mostly focused — from the technical viewpoint — on standards and protocols, this work investigates the adoption of formal methods for dependable composition. The Web Services Business Process Execution Language (WS-BPEL) — an OASIS standard widely adopted both in academic and industrial environments — is considered as a touchstone for concre...

In this paper we present an overview of techniques used to implement various image and video compression algorithms using parallel processing. Approaches used can largely be divided into four areas. The first is the use of special purpose architectures designed specifically for image and video compression. An example of this is the use of an array of DSP chips to implement a version of MPEG1. T...

High frequency models of transistors are of interest because they have applications to computeraided design of high frequency circuits. When these models are derived, a problem encountered is that measured transistor S-parameters do not agree with the hybrid-π model. In this article, a simplified method is described to obtain an optimized classical hybrid-π model that predicts the measured S-pa...

Supramolecular analytical chemistry has emerged as a new discipline at the interface of supramolecular and analytical chemistry. It focuses on analytical applications of molecular recognition and self-assembly. One of the important outcomes of the supramolecular analytical chemistry is the understanding of molecular aspects of sensor design, synthesis and binding studies of sensors while using ...
