Recently, spatial databases have attracted increasing interest in the database field. Because of the volume of the data with which they deal with, the performance of spatial database systems' is important. The R-tree ...

This paper surveys the contributions of five mathematicians\,---\,Eugenio Beltrami (1835--1899), Camille Jordan (1838--1921), James Joseph Sylvester (1814--1897), Erhard Schmidt (1876--1959), and Hermann Weyl (1885--1955 ...

Appeared in Proceedings of ACASSP-91. An algorithm for updating the null space of a matrix is described. The algorithm is based on a new decomposition, called the URV decomposition, which can be updated in $O(N^2)$ and ...

This document describes the process of integrating IDEF3 and PSL. The EPIF like frame representation developed for representing IDEF3 schematics is introduced, together with the compilation rules for the various IDEF3 ...

We present the design of the Virtual Microscope, a software system employing a client/server architecture to provide a realistic emulation of a high power light microscope. We discuss several technical challenges related ...

Programmers typically want to write scientific programs in a high level language with semantics based on a sequential execution model. To execute efficiently on a parallel machine, however, a program typically needs ...

Load imbalance is a serious impediment to achieving good performance in parallel processing. Global load balancing schemes are not adequately manage to balance parallel tasks generated from a single application. Dynamic ...

We present efficient algorithms for finding a minimum cost perfect matching, and for solving the transportation problem in bipartite graphs, G=(\Red\cup \Blue, \Red\times \Blue), where |\Red|=n, |\Blue|=m, n\le m, and the ...

Existing compilers often fail to parallelize sequential code, even when a program can be manually transformed into parallel form by a sequence of well-understood transformations (as is the case for many of the ...

In a previous experiment, we determined how various changes in three structural elements of the software inspection process (team size, and number and sequencing of session), altered effectiveness and interval. our results ...
