Research ArticleOpen accessIn the abstractGeneralization of Dijkstra’s Algorithm for Extraction of Shortest Paths in Directed MultigraphsBashir Alam, Siddhartha Sankar Biswas, M. N. DojaThe classical Dijkstra’s algorithm to find the shortest path in graphs is not applicable to multigraphs. In this study the authors generalize the classical Dijkstra’s algorithm to make it applicable to directed multigraphs. The modified algorithm is called by Generalized Dijkstra’s algorithm or GD Algorithm (GDA in short). The GDA outputs the shortest paths and the corresponding min cost. It … …Journal of Computer Science, Vol. 9, Issue 3 · 29 Apr 2013 · 7,466 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,057 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDetection of Subsurface Defects in Concrete Bridge Deck JointsWonchang Choi, Larry Rickard, Taher Abu-Lebdeh, Miguel PicornellProblem statement: The integrity of deck joints in highway bridges plays a major role to determine overall performance of bridge system. As the bridge maintenance program, the defects in deck joints have historically been detected by conventional non-destructive testing and evaluation methods such as visual inspection, chain-dragging and by the detecting sounds under the traffic. Future bridge maintenance challenges will … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 31 Dec 2011 · 7,772 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvaluation of Common Maintenance Methods for Flexible PavementsAsma T. Ibraheem, Suda M. GaniProblem statement: With the increasing use and awareness of pavement management systems and the growing emphasis on asset management of pavement infrastructure, it is important to strengthen the maintenance components of these systems and particularly the preventive maintenance component. Iraqi Roads don’t receive an effective and proper maintenance during their service life until they reach the state of major failure … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 7,859 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Novel Transporting System Model for Oil RefineryRazman Mat Tahar, Waleed K. AbduljabbarProblem statement: Oil refineries are widely used to store various liquids and gases. Petroleum products are in high demand. Oil companies have abundant resources of petroleum products in pipelines and storage tanks. Approach: Included are storage tanks at retail gasoline station, home heating oil tanks, lubricant storage at automotive service facilities, propane tanks in all sorts of application, and oil … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,870 accessesView PDF Cite
