Research ArticleOpen accessIn the abstractDetermining the Impact of Darkness on Highway Traffic Shockwave PropagationParameswary Sundara, Othman Che Puan, Mohammad Rosli HaininDuring darkness visibility diminishes resulting in reduced sight distances and drivers are subjected to anxiety that may give way to anger and frustration. However, the study is concerned with traffic shockwave propagation that could be associated with darkness on highways. Based on the hypothesis that darkness may induce temporary traffic shockwave propagation in the presence of substantial traffic volume, darkness … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,071 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFPGA-Based Architecture for a Generalized Parallel 2-D MRI Filtering AlgorithmSami Hasan, Said Boussakta, Alex YakovlevProblem statement: Current Neuroimaging developments, in biological research and diagnostics, demand an edge-defined and noise-free MRI scans. Thus, this study presents a generalized parallel 2-D MRI filtering algorithm with their FPGA-based implementation in a single unified architecture. The parallel 2-D MRI filtering algorithms are Edge, Sobel X, Sobel Y, Sobel X-Y, Blur, Smooth, Sharpen, Gaussian and Beta (HYB). Then, the … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 20 Feb 2012 · 8,021 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImplementation of Multi-Centroid Moment Invariants in Thermal-Based Face Identification SystemKhairul Hamimah Abas, Osamu OnoProblem statement: Current paramount methods and approaches in face identification field rely on facial characteristics; such as location of eyes, length of nose and mouth, regardless the type of medium used to acquire the facial images. The visibility of these facial characteristics varies significantly with environmental factors (e.g., lighting elements). Various researches have been devoted to develop methodologies for addressing … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,163 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Importance of Police Performance as a Determinant of Satisfaction with PoliceJames E. Larsen, John P. BlairProblem statement: Citizen satisfaction with police performance is an important concern of public managers because police performance is central to citizens and accounts for a large share of urban budgets. Also, there is substantial disagreement in the literature regarding determents of citizen satisfaction. Approach: Logistic regression was used to investigate the results of three public opinion surveys, conducted biannually, to … …American Journal of Economics and Business Administration, Vol. 1, Issue 1 · 31 Mar 2009 · 8,714 accessesView PDF Cite
