Given the capabilities of OO programming, its maturity and generality, it is a sane expectation to adopt OO as the paradigm of choice for XML processing. To serve that expectation, one would map XML schemas to object models so that XML data can be processed through familiar objects. The first generation of mapping technologies has been somewhat disappointing and the term X/O impedance mismatch ...

Sparse Symmetric Positive Definite (SPD) Linear System Solvers (LSS) are routinely required in various Power System Analysis problems. In sparse LSS ordering of nodes is desired to reduce fill ins, which in turn reduce computations. Minimum Degree Algorithm (MDA) has established itself as a very competitive ordering algorithm, for reducing fill ins to quite often near minimum level. With the ac...

In [9] and [10], we have studied the initial value problem for the Korteweg-de Vries (KdV) equation (1.1) ut—6uu x +u xxx =0 by the inverse scattering method. In this paper we study the asymptotic behavior of the solutions as t— >zh°°-Consider the Schrodinger equation (1.2) over (— oo } oo) with the potential u(x) satisfying (1.3) (throughout the paper integration is taken over (— oo, oo) unles...

Object Oriented (OO) metrics play a key role in determining the efficiency of the code being developed under OO approaches. Cohesion and coupling are the widely used measures applied for the determination of important factors including reusability, maintainability and readability. There exists many Cohesion and Coupling based OO metrics making it difficult to choose the appropriate one. Moreove...

This article proposes a general graph-based representation for modeling Object Oriented (OO) software designs. The advantages of the representation over the Unified Modeling Language (UML) are: it formalizes the link between primitive OO design features and primitive entities of graphs; it models all the design features of an OO design in one cohesive graph; it provides us a convenient platform...

Cohesion is one of the widely used measures applied for the determination of important factors including reusability, maintainability and readability. There exists many Cohesion based OO metrics making it difficult to choose the appropriate one. Moreover, improper applica...

Conventional OO methodologies have t o p r o vide a well-deened Component based development CBD process by which the community of software engineers could properly derive executable software components from requirements in a systematic way. The move t o ward CBD requires existing OO conceptual modeling approaches to be reconsidered. In this paper we present a proposal to support CBD in an OO Me...
