Research ArticleOpen accessIn the abstractBirds as a Tool for Island Habitat Conservation and ManagementPedro Rodrigues, Regina Tristao da CunhaProblem statement: The Azores is a archipelago of nine volcanic islands, situated in the middle of the North Atlantic Ocean. Oceanic islands are known hotspots of biodiversity and the Azores, although relatively young (0.3-13 MA), conform to this general pattern. The local avifauna amount to 37 birding species, with two endemic species and 11 endemic subspecies. With an estimated population … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 20 Jan 2012 · 8,157 accessesView PDFCite

Research ArticleOpen accessIn the abstractOptimization of Bathymetry Database for Coastal AreasWorachat Wannawong, Prungchan Wongwises, Usa W. HumphriesProblem statement: A database containing gridded bathymetries with different coverages and resolutions has been established. Approach: The interpolation techniques of the gridded bathymetries have been developed to define the spherical, rectangular and curvilinear coordinate grid systems. Results: Subsequently, merging of the bathymetry results has also been developed to define the optimal bathymetry. Furthermore, the bathymetries were established in order to … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeckle Suppression of Radar Images Using Normalized ConvolutionA. K. Helmy, G. S. El-TaweelProblem statement: Synthetic Aperture Radar (SAR) images are becoming more widely used in remote sensing applications. SAR uses microwave radiation to illuminate the earth's surface. The coherent microwave illumination, however, suffers from fading effects result in generating a multiplicative speckle noise that corrupts SAR images. Approach: Through this study, scheme to reduce speckles was proposed, it was designed to accomplish … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractLead Free Solder Joint Thermal Condition in Semiconductor PackagingM. Najib Harif, Allina Nadzri, Kamaruzaman JusoffProblem statement: Solder joints are responsible for both electrical and mechanical connections. Solder does not have adequate ductility to ensure the repeated relative displacements due to the mismatch between expansion coefficients of the chip carrier and the circuit board. Solder material plays a crucial role to provide the necessary electrical and mechanical interconnections in an electronic assembly. Finding a technique … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractVision-Based Obstacle Avoidance of Mobile Robot Using Quantized Spatial ModelSalaheddin Odeh, Rasha Faqeh, Laila Abu Eid, Nihal ShamasnehProblem statement: Problem of moving a robot through unknown environment has attracted much attention over past two decades. Such problems have several difficulties and complexities that are unobserved, besides the ambiguity of how this can be achieved since a robot may encounter obstacles of all forms that must be bypassed in an intelligent manner. This research had been aimed to … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,053 accessesView PDFCite
Research ArticleOpen accessIn the abstractUrbanization Effect on Air Temperature in Iran's Zayanderud River BasinAli Zahraei, Sara Saadati, Saeid Eslamian et al.: Detection of urbanization effect to understand climate change is important. Urbanization effect on air temperature in Zayanderud river basin was evaluated using weather stations network. Map of the temperature trend was generated using full dataset and rural stations to visualize warming trends. A comparative analysis was carried out to estimate urban heat island effect.

Research ArticleOpen accessAll words, across the recordAlgorithm for Compressing/Decompressing Sudoku GridsZhivko Nedev, Murtala Adamu Zungeru, Suykhun Khov et al.We describe a way to transfer efficiently Sudoku grids through the Internet. This is done by using linearization together with compression and decompression that use the information structure present in all sudoku grids. The compression and the corresponding decompression are based on the fact that in each Sudoku grid there are information dependencies and so some of the information is … …Journal of Computer Science, Vol. 16, Issue 9 · 3 Oct 2020 · 6,872 accessesView PDFCite
