Research ArticleOpen accessIn the abstractY: A New Component-Based Software Life Cycle ModelLuiz F. CapretzWith the need to produce ever larger and more complex software systems, the use of reusable components has become increasingly imperative. Of the many existing and proposed techniques for software development, it seems clear that component-based software development will be at the forefront of new approaches to the production of software systems and holds the promise of substantially enhancing the … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractExergoeconomic Analysis of a Refrigeration CycleDurriye Bilge, Galip TemirThe exergoeconomic theory is applied to a two stage vapour compression refrigeration cycle. An exergy-aided cost analysis, taking into account pressure drops and heat gain/loss for all of the components in the refrigeration system as well as the pipe connections, has been made. Exergoeconomic factors, showing whether the monetary expenditures mostly originate from capital investment and Operating and Maintenance (O&M) … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Optimum Numbers of Stages in Vapour Compression Refrigeration SystemsDurriye Bilge, Galip TemirIn this study, cases of single-stage and multi-stage compression have been compared and contrasted through various angles while concentrating on refrigeration systems with 600 kW cooling capacity and working with ammonia. For five different numbers of stages, power consumption, costs of investment, operation and maintenance (O and M), COP and 2nd law efficiencies have been calculated. As the amount of … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,688 accessesView PDFCite
