Research ArticleOpen accessIn the abstractEdge Detection in Gray Level Images based on the Shannon EntropyBaljit Singh, Amar P. SinghMost of the classical mathematical methods for edge detection based on the derivative of the pixels of the original image are Gradient operators, Laplacian and Laplacian of Gaussian operators. Gradient based edge detection methods, such as Roberts, Sobel and Prewitts, have used two 2-D linear filters to process vertical edges and horizontal edges separately to approximate first-order derivative of pixel … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Ethical Appraisal of Hormesis: Towards a Rational Discourse on the Acceptability of Risks and BenefitsOrtwin RennIt is ethically mandated that potential beneficial aspects of low exposure to potentially hazardous material are incorporated in the risk-benefit balancing procedure. The potential harm done by pollutants does not justify the invocation of a categorical principle. Minimisation of risk is not required if health benefits are also at stake. Society needs to find an informed consent on the threshold … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Near Real-time Early Warning System on Erosion HazardsFaisal H. Ali, Tew K. HuiWith many incidences of landslides, mudslides and erosion occurrences lately, especially in the highlands in Malaysia, properties were damaged and lives were lost. Seeing the need of resolving and minimizing such untoward incidences, a study has been embarked on developing a near real-time early warning system on erosion hazards so as to provide an early warning to the public, whenever … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Titanium Dioxide Self-Cleaning Coatings on Photovoltaic Modules for Soiling Related Losses ReductionAnnalisa Andaloro, Francesco FrontiniSeveral studies have assessed the influence of soiling deposition on Photovoltaic (PV) modules front-cover with regards to performance losses over time. In fact, soiling phenomena in PV systems are ascribed as responsible for medium and long-term yield reduction up to 16% over the first-year of outdoor exposure. Provided that PV technology is a low yield energy production source, maintaining module … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 5 Feb 2017 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Playing Surface and Shoe Type on ACL Tears in Soccer PlayersMelissa M. Mansfield, Ronald B. BucinellToday, Anterior Cruciate Ligament (ACL) tears are one of the most prevalent knee injuries, with the occurrence of ACL tears increasing drastically from approximately 80 000 in 2000 to 150 000 in 2011. Although there are many factors that contribute to an ACL tear occurring, certain environmental factors could contribute to the dramatic increase over the past couple decades, especially … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 15 Dec 2016 · 12,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Acceptance Criterion (AAC) Algorithm for Optimization ProblemsAnmar AbuhamdahOptimization methods commonly are designed for solving the optimization problems. Local search algorithms are optimization method, which are good candidate in exploiting the search space. However, most of them need parameter tuning and incapable of escaping from local optima. This work proposes non-parametric Acceptance Criterion (AC) that not relies on user-defined, which motivate to propose an Adaptive Acceptance Criterion (AAC). … …Journal of Computer Science, Vol. 11, Issue 4 · 23 Jul 2015 · 6,969 accessesView PDFCite
Research ArticleOpen accessIn the abstractEDGE PRESERVED IMAGE COMPRESSION USING EXTENDED SHEARLET TRANSFORMS. Thayammal, D. SelvathiThe motivation of the proposed compression method is to reduce the bit rate for image transmission or memory requirement for image storage while maintaining image quality. The edges are one of the prominent features in an image and they are essential for maintaining image quality. JPEG compression standards like JPEG98 and JPEG2000 produce visual artifacts in reconstructed image at low … …Journal of Computer Science, Vol. 11, Issue 1 · 15 Sep 2014 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractSafety Health Impacts of Particulate Matter from Excavation Work SitesGiuseppe Pizzo, Marina ClericoEpidemiological studies have shown a linear relationship between airborne particulates and effects on human health. This study examines the risk that can be run by populations which are exposed to significant pollutant sources such as excavation in urban areas for renovation work. The health risk assessment methodology defined by the WHO air quality guidelines for Europe was applied to assess … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 25 Jul 2012 · 7,933 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamical Model for Determining Human Susceptibility to Dengue FeverSurapol Naowarat, Thanon Korkiatsakul, I. Ming TangProblem statement: Mathematical models are a useful tool for understanding and describing the transmission of diseases such as dengue fever, one of the most prevalently emerging diseases common to tropical and subtropical areas throughout South East Asia. By taking into account human susceptibility to disease, the dynamics of a dengue disease model is proposed. Approach: Using standard methods for analyzing … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 28 Sep 2011 · 7,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonal Computer Based Clinical Programming Software for Auditory ProsthesesK. Rajakumar, P. Seetha RamaiahAuditory Prostheses (AP) are widely used electronic devices for patients suffering with severe to profound senosorineural deafness by electrically stimulating the auditory nerve using an electrode array surgically placed in the inner ear. AP mainly contains external Body Worn Speech Processor (BWSP) and internal Implantable Receiver Stimulator (IRS). BWSP receives an external sound or speech and generates encoded speech data … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,902 accessesView PDFCite
