Research ArticleOpen accessEvery word in the titleA Developed Version of Conjugate Gradient Method With a New Parameter for Dai-Liao Conjugacy Condition With an Application to Solar PanelAhmad Alhawarat, Ramadan Sabra, Mehiddin Al-Baali et al.Conjugate Gradient (CG) methods are broadly employed in solving bigger-scale unconstrained optimization problems. Two famous methods are the Hestenes–Stiefel (HS) as well as Polak–Ribière–Polyak (PRP) CG methods, which usually work well in practice. However, they cannot satisfy the Global Convergence (GC) property. To retain and enhance the previous practical behavior as well as rectify the latter difficulty, this paper constructs … …Journal of Computer Science, Vol. 21, Issue 7 · 15 Jul 2025 · 3,147 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWater Saving with Combined Irrigation MethodsAlexander Kalashnikov, Nurlan Balgabaev, Vyacheslav Zharkov et al.In the conditions of arid zones of irrigated agriculture, during the cultivation of horticultural and other crops, high air temperatures (over 25-30оС) and low relative humidity (less than 20-30%) are observed during the vegetation period of plants. In these circumstances, the combined irrigation method using drip irrigation and sprinkling allows optimizing the use of water during drip irrigation at air … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 6 Oct 2022 · 5,377 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntroducing a New Kit based on Modified Chromotropic Acid Method for Easy Determination of MethanolMohammad Reza Ghadirzadeh, Ali Rafizadeh, Akbar Fattahi et al.Methyl alcohol poisoning usually happens by use of contaminated ethanol. So, development of an easy and cost-effective method to determine methanol in these products can be helpful to diagnosemethanolintoxication. The aim of this paper is introducing a new kit based on chromotropic acid method for measuring the methanol content of alcoholic beverages. In this study, a new modified chromotropic acid … …American Journal of Pharmacology and Toxicology, Vol. 14, Issue 1 · 2 May 2019 · 10,402 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Design Method of SPEM-based Feature Methodology FrameworkChee-Yang Song, Eun-Sook ChoExisting feature methodologies have been presented primarily at the research level, lacking generalized frameworks suitable for commercial application. Critically, the absence of SPEM (Software & Systems Process Engineering Metamodel) standard compliance limits their standardization and systematization, hindering practical adoption. Furthermore, work-product-based feature methodology frameworks that facilitate methodological structuring are needed to address the evolving complexity of software development processes. This … …Journal of Computer Science, Vol. 21, Issue 11 · 26 Dec 2025 · 1,719 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparative Computational Efficiency Analysis of LSB and Hybrid Steganographic MethodsDivya Sharma, Chander PrabhaElectronic Medical Images (EMI) are of various types such as X-rays, CT scans, MRIs, etc. EMIs are generally large, but they vary in dimensions and sizes based on the body part to which they belong. Not much research has been done to secure EMIs due to their varied and large sizes, while ensuring their accessibility for real-time transmission. Where access … …Journal of Computer Science, Vol. 21, Issue 10 · 28 Nov 2025 · 2,458 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSufficient Descent Condition of the Polak-Ribière-Polyak (PRP) Conjugate Gradient Method without Line SearchAbdelrahman A., KH. I. Osman, Osman O.O. Yousif et al.Nonlinear conjugate gradient methods for unconstrained optimization problems are used in many aspects of theoretical and applied sciences. They are iterative methods, so at any iteration a step length is computed using a method called line search. In most cases, the sufficient descent condition plays an important role to prove the global convergence of a conjugate gradient method. Due to … …Journal of Mathematics and Statistics, Vol. 18, Issue 1 · 14 Mar 2022 · 6,360 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Computational Method Based on Bernstein Polynomials for Solving FredholmIntegro-Differential Equations under Mixed ConditionsMiloud Moussai, Lakhdar ChiterIn this study, a computational method for solving linear FredholmIntegro-Differential Equation (FIDE) of the first order under the mixed conditions using the Bernstein polynomials. First, we present some properties of these polynomials and the method is explained. These properties are then used to convert the integro-differential equation to a system of linear algebraic equations with unknown Bernstein coefficients. Using Galerkin … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 27 Feb 2017 · 7,142 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Solution of First Order Initial Value Problems Using a Self-Starting Implicit Two-Step Obrechkoff-Type Block MethodZurni Omar, Oluwaseun AdeyeyeThe conventional two-step implicit Obrechkoff method is a discrete scheme that requires additional starting values when implemented for the numerical solution of first order initial value problems. This paper therefore presents a two-step implicit Obrechkoff-type block method which is self-starting for solving first order initial value problems, hence bypassing the rigour of developing and implementing new starting values for the … …Journal of Mathematics and Statistics, Vol. 12, Issue 2 · 13 Jun 2016 · 8,078 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExtended Kalman Filter versus Newton-Lowe's Method for Robot Pose EstimationMohammad Ehab RagabIn this work, we study the pose estimation problem of anautonomous mobile robot. Particularly, we compare the Extended Kalman Filter (EKF) to Lowe's method based on the iterative Newton's method for solving a system of nonlinear equations. Although the EKF is recursive which renders it suitable for the real-time problem at hand, Lowe's method has much less dimensionality. This is … …Journal of Computer Science, Vol. 11, Issue 7 · 5 Nov 2015 · 6,937 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBioanalytical Method Validation and Quantification of Flupirtine in Canine Plasma by HPLC with Spectrofluorimetric DetectionVirginia De Vito, Alessandro Saba, Helen Owen, Mario GiorgiFlupirtine (FLU) is a non-opioid analgesic drug belongs to the class of N-Methyl-D-Aspartate (NMDA) antagonist without antipyretic or antiphlogistic properties. No analytical method to detect FLU in canine plasma samples through a fluorimetric detector has been published to date. The analytical method described in this work provides a selective and accurate quantification of FLU.
