EditorialOpen accessIn the abstractRECENT TRENDS AND CHALLENGES OF ENERGY EFFICIENT AND SUSTAINABLE BUILDINGSChiara BedonAccording to several studies (e.g., the Intergovernmental Panel on Climate Change (IPCC, 2014), the US Energy Information Administration (US EIA, 2014), warming of the climate system is unequivocal and mainly derives from greenhouse gas emissions due to human activities. Global Carbon Dioxide (CO2) emissions from fossil fuels, for example, are estimated to be 29% higher in 2035 than they were … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 11 Sep 2014 · 8,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractA USER PROTECTION MODEL FOR THE TRUSTED COMPUTING ENVIRONMENTMarwan Ibrahim Alshar’e, Rossilawati Sulaiman, Mohd Rosmadi Mukhtar, Abdullah Mohd ZinInformation security presents a huge challenge for both individuals and organizations. The Trusted Computing Group (TCG) has introduced the Trusted Platform Module (TPM) as a solution to end-users to ensure their privacy and confidentiality. TPM has the role of being the root of trust for systems and users by providing protected storage that is accessible only within TPM and thus, … …Journal of Computer Science, Vol. 10, Issue 9 · 15 Apr 2014 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputational Techniques for Stability Analysis of a Class of Dynamic Economic ModelsGeorge E. Halkos, Kyriaki D. TsilikaModern microeconomics and macroeconomics study dynamic phenomena. Dynamics could predict future states of an economy based on its structural characteristics. Dynamic models in discrete time discrete state economic systems may take the form of one single linear difference equation or a system of linear difference equations. In this study we use Xcas and Mathematica as software tools in order to … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 12 Dec 2012 · 7,379 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Quasi Delay Insensitive Reduced Stack Pre-Charged Half Buffer based High Speed Adder using pipeline templates for Asynchronous CircuitsD. Jayanthi, M. RajaramProblem statement: Recent research in asynchronous design technique is making asynchronous circuits an increasingly practical alternative. These challenges include the increasing pressure for low power, the growing challenges of predicting the increasing impact of wire load and delay and the performance penalty associated with supporting communication between different clock domains Asynchronous is binary signals, but there is no common or … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jun 2012 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstrained Probabilistic Economic Order Quantity Model under Varying Order Cost and Zero Lead Time Via Geometric ProgrammingKotb Abd-El-Hamid Mahmoud Kotb, Huda Mohamed Hamid Al-ShanbariProblem statement: In this study, we provide a simple method to determine the inventory policy of probabilistic single-item Economic Order Quantity (EOQ) model, that has varying order cost and zero lead time. The model is restricted to the expected holding cost and the expected available limited storage space. Approach: The annual expected total cost is composed of three components (expected … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 3 Nov 2011 · 7,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Alternative Solutions Regarding Conservation AgricultureReza Movahedi, Hadi Fathi, Mousa Aazami, Somaye LatifiProblem statement: Studies show that no effective measures have been taken towards conservative agriculture in Iran. Social, economical and technical agricultural factors and conditions need to be provided to meet conservation agriculture at the farm, regional and national level. Accordingly, this research aimed at exploring some solutions to protect and conserve agriculture. Approach: To achieve this, of all 100 populations, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 31 Jan 2011 · 7,944 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrength Pareto Evolutionary Algorithm based Multi-Objective Optimization for Shortest Path Routing Problem in Computer NetworksSubbaraj Potti, Chitra ChinnasamyProblem statement: A new multi-objective approach, Strength Pareto Evolutionary Algorithm (SPEA), is presented in this paper to solve the shortest path routing problem. The routing problem is formulated as a multi-objective mathematical programming problem which attempts to minimize both cost and delay objectives simultaneously. Approach: SPEA handles the shortest path routing problem as a true multi-objective optimization problem with competing … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 8,216 accessesView PDFCite

IsmailProblem statement: In the area of globalization the degree of competition in the market increased and many companies attempted to manufacture the products efficiently to overcome the challenges faced. Approach: Mixed model assembly line was able to provide continuous flow of material and flexibility with regard to model change. The problem under study attempted to describe the mathematical programming limitation … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractMNM1D: A Numerical Code for Colloid Transport in Porous Media: Implementation and ValidationTiziana Tosco, Rajandrea SethiProblem statement: Understanding the mechanisms that control the transport and fate of colloidal particles in subsurface environments is a crucial issue faced by several researchers in the last years. In many cases, natural colloids have been shown to play a major role in the spreading of strongly sorbing contaminants, while manufactured micro-and nanoparticles, which are nowadays widely spread in the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 8,291 accessesView PDFCite
Research ArticleOpen accessIn the abstractTraveling Salesman Approach for Solving Petrol Distribution Using Simulated AnnealingZuhaimy Ismail, Wan Rohaizad Wan IbrahimThis research presents an attempt to solve a logistic company's problem of delivering petrol to petrol station in the state of Johor. This delivery system is formulated as a travelling salesman problem (TSP). TSP involves finding an optimal route for visiting stations and returning to point of origin, where the inter-station distance is symmetric and known. This real world application … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,194 accessesView PDFCite
