Research ArticleOpen accessPhrase in the titleOptimal Boundary Control of the Incompressible Fluid Problems in Rotation formJia LiuProblem Statement: We consider the optimal boundary control of the linearized Navier-Stokes problem. Both the Stokes problem and Oseen problem in rotation form are considered. Approach: We use the Mark and Cell (MAC) discretization method to discretize the optimization problem with linear constraints including the Stokes problem and the Oseen problem in rotation from. Then Reduced Hessian methods are to … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,277 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamics of Mobile Phosphorus and Potassium in the Soils of Agricultural Lands of Kostanay RegionAlmabek Nugmanov, Aliya Yskak, Tatiana Paramonova et al.Soil phosphorus deficiency is a growing constraint on crop productivity in the agricultural lands of the Kostanay Region, Republic of Kazakhstan, yet systematic data on the spatial dynamics of mobile phosphorus and potassium across soil types remain limited. This study assessed the availability of mobile forms of phosphorus and potassium, alongside key physicochemical properties, including soil pH and cation exchange … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 14 Apr 2026 · 1,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractOmni-Zernike Algorithm for Template Matching in Catadioptric SystemAnisse Khald, Amina Radgui, Mohammed RzizaImage descriptor have been widely applied in many computer visions and image understanding applications including pattern recognition, robotic, video surveillance, camera calibration and image retrieval, etc. Invariants features are robust when apply several transformations of photometry (illumination, blur, noise, JPEG compression) and transformations of geometry (scaling, rotation, translation and viewpoint change). In this study, we present representation and matching region … …Journal of Computer Science, Vol. 16, Issue 12 · 30 Dec 2020 · 6,501 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnrolment and Matching of Fingerprints using Minutiae TreePraseetha V.M., S. VadivelAutomated fingerprint matching is considered as the most challenging phase of fingerprint recognition since it can be affected by a variety of factors such as noise, skin condition, rotation, distortions and displacements. When there is a large database, the search time to get a matching fingerprint will be relatively high. To reduce the searching time in the database, we have … …Journal of Computer Science, Vol. 15, Issue 3 · 15 Mar 2019 · 7,566 accessesView PDFCite
Research ArticleOpen accessIn the abstractNonlinear Analysis of RC Box Culverts Resting on a Linear Elastic SoilDaniele Baraldi, Fabio Minghini, Enrico Tezzon, Nerio TulliniIn the analyses presented, the soil-structure interaction is accounted for by means of a FE-BIE approach, in which the structure is modelled with displacement-based beam finite elements, whereas the boundary between structure and substrate is described in terms of surface tractions by means of a boundary integral equation incorporating a suitable Green's function. This mixed formulation ensures full continuity between … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 8 Feb 2018 · 12,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractSwitching from Flat to Spatial Motion to 3R Mechatronic SystemsRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThe anthropomorphic robots are part of the classical series of mechatronic systems, being in the form of arms and having at least three space rotation, to which other components may eventually be added, thus lengthening the entire kinematic chain. You can also add all the planetary or spatial rotating arms or others that are translating. At the end we always … …Journal of Mechatronics and Robotics, Vol. 2, Issue 1 · 22 Jan 2018 · 7,427 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometry and Determining the Positions of a Plan Transporter ManipulatorRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The conveyor mechanism (working in a plan) to be presented in this study is a classic case of manipulating conveyor, simply with a single degree of mobility. It is a very common mechanism used in classical mechanics, being encountered at lifting platforms, at handicapped chairs, at cranes, forklifts, automatic machines and machines, or at older steam locomotives where it having … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 1 Jan 2018 · 6,551 accessesView PDFCite
InvestigationOpen accessIn the abstractDeveloping a System of Organic Farming Technologies to Obtain Environmentally Clean Agricultural Products (Organic Food) in the Steppe Zone of the Kostanai RegionAlmabek Batyrzhanovich Nugmanov, Yuriy Valerievich Tulayev, Saniya Abiltaevna Tulkubayeva, Svetlana Vladimirovna SomovaThe goal of the research is to study the opportunity to produce environmentally clean agricultural products (organic food) under the conditions of the Kostanai Region. The researches were made in two crop rotations: cereal laying fallow, two-field crop rotation (1 – biologized fallow – mustard, 2 – wheat) and cereal laying fallow, two-field crop rotation (1 – biologized fallow – … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 23 Dec 2017 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometry and Direct Kinematics to MP3R with 4×4 OperatorsRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.Anthropomorphic mechatronic systems are the most widely used robotics systems worldwide today in industry and in all automated environments.
