Research ArticleOpen accessIn the abstractEstimation of the COCOMO Model Parameters Using Genetic Algorithms for NASA Software ProjectsAlaa F. ShetaDefining the project estimated cost, duration and maintenance effort early in the development life cycle is a valuable goal to be achieved for software projects. Many model structures evolved in the literature. These model structures consider modeling software effort as a function of the developed line of code (DLOC). Building such a function helps project managers to accurately allocate the … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 9,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractQualitative Assessments of the Software Architectures of Configuration Management SystemsAbhay Kothari, A. K. Ramani, P. K. ChandeThe Configuration Management (CM) is a very important area of concentration in software development and maintenance processes. Quality parameters for Configuration Management Tools’ architectural designs require rigorous identification and measurement. Two methods for quantitative assessment of quality parameters of the software architectures are proposed. These methods are based upon modularization properties, like, cohesion type, coupling type, module complexity, module size … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards Autonomously Developed Software: A genetic Approach in Critical and Embedded SystemsDjamel Meslati, Saïd GhoulNowadays, we are still considering changes undergone by a software system as a sporadic phenomenon and we do not sufficiently anticipate future changes during the development phase. Consequently, many problems arise in the maintenance phase. In this study, we present an approach where all changes undergone by a software system are considered as its ontogenetic dimension. We represent this dimension … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,191 accessesView PDFCite

Research ArticleOpen accessIn the abstractThe Impacts of Total System Design Factors on Human Performance in Power PlantsA. Azadeh, J. Nouri, I. Mohammad FamThe objective of this study is to evaluate the impact of total system design factors (TSD) on human performance in a power plant. The TSD factors are defined as design factors, which have an impact on the overall performance of the power plants in the context of total human engineering or macroergonomy. The systems being studied are the control rooms … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Stability of a Certain Class of Linear Time-Varying SystemsM. De la SenThis study firstly considers the exponential stability of unforced linear systems of slowly time-varying dynamics. Possible switchings of the system structure to unstable dynamics during certain finite time intervals are admitted. The maintenance of global exponential stability does not necessarily require at most a finite number of switchings in the dynamics while infinitely many switches can also lead to stability. … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,935 accessesView PDFCite

Research ArticleOpen accessIn the abstractGender Differences in Baseline Levels of Vascular Endothelial Growth Factor in the Plasma of Alaskan Sled DogsScott W. Kemp, Arleigh J. Reynolds, Lawrence K. DuffyAngiogenesis and vasculogenesis are two very important processes in the development and maintenance of mammalian health. In sled dogs, the angiogenic role is to supply and support tissue with ample vasculature, thus providing a route of access for the transportation of essential nutrients, including oxygen and the removal of waste in a sustained fashion. VEGF has been shown to be … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,318 accessesView PDFCite
