Research ArticleOpen accessIn the author namesComparison of Daily and Monthly Results of Three Evapotranspiration Models in Tropical Zone: A Case StudySeyed Reza Saghravani, Sa’ari Mustapha, Shaharin Ibrahim, Elias RandjbaranProblem statement: Evapotranspiration (ET) has crucial role in agricultural activity, water management and hydraulic engineering. Recently many forms of the equation have been applied for estimating daily and monthly evapotranspiration around the world. Approach: In this study, the daily and monthly ET was estimated by Penman, Penman-Monteith (P&M) and Hargreaves equation to evaluate general relationships for estimating monthly and daily … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,648 accessesView PDFCite
Research ArticleOpen accessIn the author namesAtomic Layer Epitaxial Growth of Gaas on Porous Silicon SubstrateMohamed Lajnef, Afrah Bardaoui, Isabelle Sagne et al.GaAs thin film has been grown on porous silicon by metal organic chemical vapour deposition (MOCVD) for different growth temperatures using atomic layer epitaxy (ALE) technique. The morphology of GaAs layer was investigated by atomic force microscopy (AFM). The effect of growth temperature is studied using photoluminescence measurements (PL).The photoluminescence spectra revealed a dissymmetry form toward high energies attributed to … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,029 accessesView PDFCite
Research ArticleOpen accessIn the author namesEfficient Physical Organization of R-Trees Using Node ClusteringF. Sagayaraj Francis, P. ThambiduraiR-Tree is a multidimensional indexing structure that forms basis for all the multidimensional indexing structures based on data partitioning. A number of attempts have been made in the past to improve the performance of R-Tree by manipulating the tree parameters and the data parameters. But hardly any attempt had been made to use external parameters such as disk parameters to … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,628 accessesView PDFCite
Review ArticleOpen accessIn the abstractReview of Signal Processing Techniques for Detection of Power Quality EventsAbhijith Augustine, Ruban Deva Prakash, Rajy Xavier, Mareeta Cheriyan ParasseryThe challenging process industry requires true power for its smooth functioning and here comes the importance of good power or power. The term Power Quality (PQ) aims at supplying true power to the process. The scope of the power quality increased with the introduction of newly designed sophisticated devices like computers and microcontrollers. The performances of these devices are extremely … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 30 Apr 2016 · 8,498 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEWER DRUGS FOR VISCERAL LEISHMANIASIS: A REVIEWKrishna Pandey, Dharmendra Singh, Sanjiva Bimal et al.Visceral Leishmaniasis (VL) is one of the most neglected tropical diseases worldwide. The diagnosis and treatment of this disease is quite complex. Sodium Antimony Gluconate (SAG) which used to be a very effective treatment has now developed resistance and is potentially a cardio-toxic drug. Pentamidine has now been discarded because of adverse effect of diabetes mellitus. Amphotericin-B is an effective … …American Journal of Infectious Diseases, Vol. 10, Issue 2 · 5 May 2014 · 7,135 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of the Unified Series-Shunt Compensator for Power Quality MitigationM. A. Hannan, A. Mohamed, A. Hussain, Majid al DabbayThis study describes the derivation of an analytical model and simulation for the unified series-shunt compensator (USSC) for investigating power quality in power distribution system. The USSC simulation comprises of two 12-pulse inverters which were connected in series and in shunt with the system. A generalized sinusoidal pulse width modulation (SPWM) switching technique was developed in the proposed controller for … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,639 accessesView PDFCite
Research ArticleOpen accessIn the abstractSystematic Literature Review of Graph Neural Networks in Disaster Management: Methods, Applications, and Future DirectionsSularno, Wendi Boy, Putri Anggraini et al.The increasing frequency and complexity of natural disasters underscore the urgent need for intelligent systems that support timely and effective decision-making. Graph Neural Networks (GNNs) have emerged as a powerful deep-learning paradigm for modeling spatial and relational data, offering distinct advantages for disaster management. This study presents a Systematic Literature Review (SLR) of GNN-based approaches for disaster mitigation, emergency response, … …Journal of Computer Science, Vol. 22, Issue 2 · 17 Feb 2026 · 2,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractCadmium Stress Responses in Medicinal and Oilseed Plants: Safflower as a Promising Candidate for Soil Cadmium RemediationChristos Kikis, Giorgos Thalassinos, Vasileios AntoniadisThis study investigated the growth responses of five economically important plants—chamomile (Matricaria recutita), oregano (Origanum vulgare), safflower (Carthamus tinctorius), sage (Salvia officinalis), and wormwood (Artemisia absinthium) exposed to increasing Cd levels. Over 60 days, plants were subjected to Cd concentrations of 0, 1, 2, 3, and 4 mg per pot. Growth parameters and Cd accumulation were then assessed. At the … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 13 Nov 2025 · 3,414 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of the Efficacy of Landslide Susceptibility ModelsJordan Henrique de Souza, Gislaine dos Santos, Gabriela Guimarães Gouvêa de Oliveira et al.This research aims to analyze the efficacy of SHALSTAB, IPT, SAGA, SMORPH and modified SMORPH models in evaluating landslide susceptibility. Statistical analysis concerning both the efficacy of the models in the prediction of landslide risks and the concordance between the models according to landslide occurrence or non-occurrence was performed. For this work, logistic regression, Receiver Operating Characteristic (ROC) curves, Kappa … …American Journal of Environmental Sciences, Vol. 15, Issue 3 · 31 May 2019 · 8,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractNuclear Posture Review: Kahn Vs. Schelling…and PerryTimothy Sands, Harold Camacho, Richard MihalikThe 2018 American Nuclear Posture Review includes a revived emphasis on deployed, low-yield nuclear options to reserve credible deterrence against countries that have transmitted beliefs the U.S. would not respond to employment of non-strategic nuclear weapons, since there is a mistaken perception that the U.S. could only respond with high-yield strategic weapons, which would be deemed unacceptable. An important question … …Journal of Social Sciences, Vol. 14, Issue 1 · 30 Apr 2018 · 9,278 accessesView PDFCite
