Elgibaly, Abdul Rehman KhanWaste management became focus of attention of many researchers and scientists in the last half century due to its vital importance. Waste management covered waste source reduction in general, by recycling, reusing, composting, incineration with or without energy recovery, fuel production and land filling. A common approach of waste management models were for specific problems with a limited scope (like … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Empirical Validation of Object-Oriented Design Metrics for Fault PredictionJie Xu, Danny Ho, Luiz F. CapretzProblem Statement: Object-oriented design has become a dominant method in software industry and many design metrics of object-oriented programs have been proposed for quality prediction, but there is no well-accepted statement on how significant those metrics are. In this study, empirical analysis is carried out to validate object-oriented design metrics for defects estimation. Approach: The Chidamber and Kemerer metrics suite … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,992 accessesView PDFCite
Research ArticleOpen accessIn the abstractWhat Accounts for Growth in African AgricultureGuy B. Nkamleu, Kalilou Sylla, Abdoulaye ZononEmpirical relationships between the rates of growth and total factor productivity growth, physical input accumulation, as well as institutional and agro-ecological change is evaluated using an international panel data set on 26 African countries and covering the period 1970-2000.

Research ArticleOpen accessIn the abstractRoad Transport Congestion Costs Calculations Adaptation to Engineering ApproachMarjan Lep, Beno MesarecThe article represents so called "engineering" approach for computing the total road transport congestion costs. According to economic welfare theory, the total costs of transport congestion are defined as dead weight loss (DWL) of infrastructure use. With a set of equations DWL could be formulated in a mathematical way. Because such form of equation is not directly applicable for concrete … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,817 accessesView PDFCite
