Research ArticleOpen accessIn the abstractRainfall Depth-Duration-Frequency Relationships for South Carolina, North Carolina, and GeorgiaJ. P. Raiford, N.M. Aziz, A.A. Khan, D.N. PowellThe depth-duration-frequency curves and isopluvial maps for the region encompassing South Carolina, North Carolina, and Georgia were developed using the available rainfall data. The aim was to update the existing intensity-duration-frequency curves in the region and obtain these curves at ungauged sites throughout the region using the newly developed rainfall frequency analysis techniques. A total of 17 durations ranging from … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,323 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffects of Competing Lexical Distracters in a Visual Search TaskJeremy W. Grabbe, Tom Cioffi, Luke T. Zauner et al.Studies have shown that distracters that are relevant to a target can negatively affect visual search performance. Recent studies have looked at performance when targets are embedded within a distracter. Various factors have been explored such as automaticity, spatial location and timing. This study asked, "If distracters affected a different dimension would that produce a detriment to visual search performance"? … …Current Research in Psychology, Vol. 4, Issue 2 · 16 Jan 2014 · 7,373 accessesView PDFCite
Research ArticleOpen accessIn the abstractEdge Sensing Demosaicing Using Adaptive Weighted InterpolationDev R. Newlin, Elwin Chandra MonieDemosaicing is a process of obtaining a full color image by interpolating the missing colors of an image captured from a digital still and video cameras that use a single-sensor array. The edges are not handled properly in the existing demosaicking methods. This study provides an effective demosaicing algorithm applying an adaptive weighted-edge interpolation to handle green pixels. Due to … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 29 Apr 2013 · 6,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE THEORETICAL SIMULATION OF AXIAL VIBRATIONS IN FINITE CYLINDRICAL PIEZOELECTRIC SHELL MADE OF THE TRIGONAL (3M) CRYSTALH. Zeynali, B. Jazi, R. KarimiThe axial vibration in a thin layer of finite cylinder made of trigonal (3M) piezoelectric crystal are investigated. By using a closed form solution of the equations of motion and applying new boundary conditions the effects of the geometrical dimensions, axial hydrostatic pressure and electrostatic potential along the axis of the cylinder shell on oscillation frequency and amplitude of spatial … …Physics International, Vol. 4, Issue 1 · 15 Feb 2013 · 6,918 accessesView PDFCite

Research ArticleOpen accessIn the abstractPerformance Optimization of Discrete Wavelets Transform Based Image Watermarking Using Genetic AlgorithmsA. Al-Haj, A. Abu-ErrubThe excellent spatial localization, frequency spread and multi-resolution characteristics of the Discrete Wavelets Transform (DWT), which were similar to the theoretical models of the human visual system, facilitated the development of many imperceptible and robust DWT-based watermarking algorithms. There had been extremely few proposed algorithms on optimized DWT-based image watermarking that can simultaneously provide perceptual transparency and robustness since these … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,324 accessesView PDFCite
