Research ArticleOpen accessEvery word in the titleTracking Error Analysis of a Rotation-Elevation Mode HeliostatOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanFor the past few years, great efforts have been done in improving the tracking accuracy of a newly proposed rotation-elevation tracking mode heliostat. A special simulation program has been developed to systematically analyze the image movement and to find out the error of the parameters. In the simulation program, ray-tracing method was applied to work out the central point position … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,251 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProduction and Nutritional Quality of low elevation zone Grasslands and Kermes Oak Shrublands (Quercus coccifera L.) in the South-East Mediterranean BasinC. Roukos, K. Papanikolaou, S. Kandrelis et al.Problem statement: The objective of this study was to evaluate the production and nutrition quality of grasslands and kermes oak shrublands in Preveza Prefecture, northwest Greece. Approach: The study involved the collection of herbage and browse samples along a grazing period, from March to October for two consecutive years. In consequence, browse samples were manually separated to leaves and twigs. … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLandslide Susceptibility Assessment using Frequency Ratio Model Applied to an Area along the E-W Highway (Gerik-Jeli)Tareq H. Mezughi, Juhari Mat Akhir, Abdul Ghani Rafek, Ibrahim AbdullahProblem statement: The study area is frequently subjected to landslides especially alongside the E-W high way. This study demonstrates the implementation of the Frequency Ratio (FR) model with the aid of GIS tool to assess the contribution of every predisposing factor on landslides and produce a landslide susceptibility map to the area. Approach: A landslide location map of the study … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 9,093 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRadar Cross Section Modelling and Analysis of Static and Dynamic Targets using MATLABPunam Pande, Sreemathy R, Mousami TurukRadar Cross Section (RCS) is an important characteristic of the electromagnetic system for target detection. This study presents detailed modelling of Radar Cross Section (RCS) of static simple objects like sphere, cylinder, triangular plate, circular flat plate, truncated cone and complex objects using MATLAB Radar toolbox. The RCS modelling of simple objects is also done with MATLAB POFACET GUI 4.3 … …Journal of Aircraft and Spacecraft Technology, Vol. 6, Issue 1 · 21 Mar 2022 · 11,024 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRelationship between Architectural Outer Shape and Function of Buildings: Behaviour Study on Building Constructed in ChinaISSA. A.M. Al-Kahtani, Suhaib Yahya Kasim Al-DarziThe present study attempted to investigate the behaviour of some projects designed and constructed in China during the last decades from an architectural view point and their compatibility with respect to the relationship between the outer shape and function of the building. The study includes different groups of architectural works including; Culture architecture, Education architecture, Office architecture and Hotel architecture … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,082 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMethodology for Selecting the Locaiton of an Optimum Viewing Point for an Ideal 3D Perspective View of a Given 3D EnvironmentN. Sandya Rani, V. VaithyaNathanLiterature review reveals that there exists, many methods for 3D visualization of a given object or a set of objects[1,2]. To name a few commonly used methods, we have Stereoscopic 3D visualization[3], Cross eye visualization, Parallel eye visualization, Perspective 3D visualization etc. An optimu location of the viewing point for an ideal 3D perspective view is attempted in this paper. … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 6,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractOxidative Stress Response of Black Soldier Flies Fed a Mixed Cake of Coffee and Fruit WasteEman Alaaeldin AbdelfattahThe worldwide elevation in population and consumption has exacerbated the issue of sustainable agricultural waste management, mainly for fruit and coffee waste. The black soldier fly (Hermetia illucens) is gaining responsiveness as a valued bioconversion agent for waste management, accomplished by producing multiple derived products. This study investigates the influence of a mixed cake composed of Coffee Grounds (CW) and … …American Journal of Agricultural and Biological Sciences, Vol. 19, Issue 1 · 20 Feb 2025 · 8,963 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Maize Potato Intercropping and Different Fertilization Methods on Rhizosphere Soil Microorganisms and Yield of PotatoHuanjin Ma, Shengguang Xu et al.A field experiment with three replicates was conducted to explore the effects of maize-potato intercropping and different nitrogen application strategies on rhizosphere soil microorganisms and potato yield. Microbial community analysis was based on relative abundance. Maize-potato intercropping improves land use efficiency, yet how differentiated nitrogen management regulates rhizosphere microecology and potato productivity in this system remains unclear. Clarifying nitrogen-mediated shifts … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 14 Sep 2026 · 790 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Forest and Extreme Gradient Boosting with Bayesian Hyperparameter Optimization for Landslide Susceptibility Mapping in Penang Island, MalaysiaDorothy Anak Martin Atok, Soo See Chai, Kok Luong Goh et al.Landslide susceptibility models often face challenges of overfitting and overestimation. This research focuses on improving the predictive capabilities of the Extreme Gradient Boosting (XGBoost) and Random Forest (RF) algorithms by applying Bayesian Hyperparameter Optimization (BayesOpt). Penang Island, a region in Malaysia prone to frequent landslides, was chosen as the study area. Ten Landslide Conditioning Factors (LCFs), including elevation, slope angle, … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 3,103 accessesView PDFCite
Review ArticleOpen accessIn the abstractModeling the Nile: A Comprehensive Water Budget and Flow Assessment with the River Basin Flow Model (RBFM)Youssef Ismail HafezThe Nile River basin, covering 2.9 million km³ across 11countries, is one of the world's most complex hydrological systems. With an annual historical discharge of 84 billion m³ at Aswan, Egypt, and rainfall of around 1,660 billion m³ per year over the Nile basin, effective management of this vital transboundary resource requires a deep understanding of its hydrology.
