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 · 7,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltra Wide Band (UWB) Ad-hoc Networks: Review and TrendsRashid Saeed, Sabira Khatun, Borhanuddin M. Ali, Mohd K. AbduallahShort-range wireless systems have recently gained a lot of attention to provide seamless, multimedia communications around a user-centric concept in so called Wireless Personal Area Networks (WPAN). Ultra-Wide Band (UWB) technology presents itself as a good candidate for the Physical Layer (PHY) of WPAN, both for high and low data rate applications. Many ongoing developments of Ultra-Wide Band (UWB) system … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractBinding of the scutellarin to albumin using tryptophan fluorescence quenching, CD and FT-IR spectraJianniao Tian, Jiaqin Liu, Zhide Hu, Xingguo ChenThe binding of scutellarin with bovine serum albumin (BSA) was investigated at three temperatures, 296k, 310K, and 318K, by the fluorescence, circular dichroism (CD) and fourier transform infrared spectroscopy (FT-IR) at pH 7.40. The binding parameters were determined by Stern-Volmer equation. The thermodynamic parameters were calculated according to the dependence of enthalpy change on the temperature as follows:ΔH0 and ΔS0 … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 13,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractWork Performance of MB Trac 900 Tractor on Mountains Terrain in TurkeyTolga Ozturk, Murat DemirThe forestry works mainly involves such various stages as growing, protection, production, wood harvesting, marketing and utilization of forest products. Wood harvesting is performed by completion of cutting, extraction and transporting stages. The most obvious feature of wood harvesting is that the operations are done under various weather conditions open in the field. The measurements and observations were made on … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,317 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 · 7,149 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 · 6,691 accessesView PDFCite
