Research ArticleOpen accessIn the abstractEvaluation of a New Device, Automated Shower head on Water Conservation in Bath ShowersM. Shamsi, G. H.S. BonjarIn cosmopolitan areas and big cities of the world, shortage of drinking water during the peaks of consumption hours is a noticeable problem. Many people may not have piped water during these critical hours especially in summer times. To minimize this problem, an electronic control valve was designed and developed which saved about 70% of water in each showering session … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,202 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of a New Model for Evaluation of Iran Ecological Capabilities in Order to Establish Services and Civil Development ApplicationJ. Nouri, S. A. JoziThis study is aimed to design a new model for service and civil development application in order to be used in evaluation of Iran ecological capability studies. For this purpose in the first step, the frequency of sustainable and unsustainable ecological factors in Iran was known. In the next step, the Delphi method was used which is itself a branch … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,519 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Growth Medium for Centella Asiatica Cell Culture Via Response Surface MethodologyRozita Omar, M. A. Abdullah, M. A. Hasan, M. MarziahThe effects of sucrose, Indole-3-Acetic Acid (IAA) and 6-BenzylAminoPurine (BAP) concentrations on cell growth of Centella asiatica cell suspension culture were studied. The concentrations were designed using Central-composite experimental design and regression analysis was carried out to obtain response surface model describing cell growth for prediction of optimum conditions. Only sucrose as a single factor was positively significant for cell … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,206 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simple Scheme for Improved Performance of Fixed Outage Rate Cellular SystemHussein M.Aziz Basi, M. B.R. MurthyThe traffic characteristic of mobile cellular systems is rather distinct from that of a fixed telephone network. However the system planning and design are still carried out with the tools of conventional traffic theory. In the recent days much work is being done in the performance evaluation of mobile or cellular communication systems in order to develop a system with … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,085 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 abstractQuality Control of Coffee Using an Electronic Nose SystemNidal F. Shilbayeh, Mahmoud Z. IskandaraniAn electronic nose system for quality control of coffee is designed and tested. The system uses the Figaro TGS800 series sensors with an integrated heating element. The testing of the system is carried out using different types of coffee where it is proved successful in classifying the tested coffees and actual discrimination of ingredients into different classes[10]. Database based software … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,544 accessesView PDFCite
Research ArticleOpen accessIn the abstractInformation Provided by Accrual and Cash Flow Measures in Determining Firms’ Performance: Malaysian EvidenceNorita Mohd Nasir, Shamsul Nahar AbdullahAccrual and cash flow measures have been argued to be able to evaluate firms’ performance, although the results are inconclusive throughout countries and time. This study examined the accrual and cash flow measures independently and jointly among Malaysian firms. The study predicted that the low cash flow subgroups (high income to cash flow firms) would show better results in operating, … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,330 accessesView PDFCite
Research ArticleOpen accessIn the abstractParallel Iterative Algorithms with Accelerate Convergence for Solving Implicit Difference EquationsQing-Fu Liu, Wei-Jun Zhong, Mancho ManevThis study focuses on the solution of implicit difference equations, which are very difficult to compute in parallel for the diffusion equation. For improving the convergence rates and the properties of gradual-approach convergence of Segment-Classic-Implicit-Iterative (SCII) and Segment-Crank-Nicolson-Iterative (SCNI) algorithms realizing efficient iterative computation in parallel by segmenting grid domains, SCII and SCNI algorithms with accelerated convergence are studied and … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 6,801 accessesView PDFCite
Research ArticleOpen accessIn the abstractSmall Business Critical Success/Failure Factors In Developing Economies: Some Evidences From BotswanaZelealem T. Temtime, J. PansiriAlthough the discovery of diamond has propelled Botswana from one of the poorest countries in 1966 to its current economic status as a middle-income country, the country still faces the problems of economic diversification, employment creation, income generation and distribution and poverty alleviation. Governmental and non- Governmental organizations have put many efforts on the development of small and medium Enterprises … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 9,324 accessesView PDFCite
