Research ArticleOpen accessEvery word in the titleQuaternion Photometric Stereo for Rotation Invariant Surface Texture ClassificationBalakrishnan Sathyabama, Srinivan Raju, Abhaikumar VaradhanProblem statement: The escalating growth of computer vision applications has increased the need for faster and more accurate image analysis algorithms. One application of image analysis that has been studied for a long time is texture analysis. The majority of existing texture analysis methods makes the explicit or implicit assumption that texture images are acquired from the same viewpoint. This … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 6,499 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the keywordsPasture Productivity Depending on the Method of Pasture use in the Steppe Zone of Northern KazakhstanBalzhan Akhylbekova, Nurlan Serekpayev, Adilbek Nogayev, Bakhytbek ZhumabekUnsystematic grazing of animals and continuous use of pastures leads to their degradation and, accordingly, to a shortage of pasture forage for the production of competitive environmentally friendly livestock products. The proportion of productive grasses in grass covers is decreasing; therefore, there is an urgent need to preserve valuable plant species in pasture grass, restore the productivity of natural vegetation … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 3 Nov 2022 · 5,909 accessesView PDF Cite

InvestigationOpen accessIn the keywordsDeveloping 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 PDF Cite

Research ArticleOpen accessIn the keywordsDeficient Reasoning for Dark Matter in GalaxiesJames Q. Feng, C.F. GalloIn this universe, not all of the matter around us can be readily seen. The further an object is away from us and the less luminous it is, the less visible it becomes. Just by looking at an object is usually difficult, if not impossible, to tell the amount of mass it contains. But astronomers have been using the measured … …Physics International, Vol. 6, Issue 1 · 14 Sep 2015 · 8,285 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Polishing of Cutting-Edge Polymer-on-Glass for Pigtailing PreparationMohammad Syuhaimi Ab-Rahman, Fazlinda Ab-Aziz, Noor Azie Azura Mohd Arif et al.Problem statement: The high quality of cutting-edge surface is important in optical waveguide's efficiency. The perfect polishing of end surface is significant to deliver the best quality of light waves and minimize the device losses such as insertion loss and return loss. Hence, this research is concern on the parameters in polishing SU-8 polymer to increase the efficiency of waveguide. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 9,148 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA COSSERAT-TYPE PLATE THEORY AND ITS APPLICATION TO CARBON NANOTUBE MICROSTRUCTUREAbdellatif Selmi, Hedi Hassis, Issam Doghri, Hatem ZenzriThe predictive capabilities of plate and shell theories greatly depend on their underlying kinematic assumptions. In this study, we develop a Cosserat-type elastic plate theory which accounts for rotations around the normal to the mid-surface plane (so-called drilling rotations). Internal loads, equilibrium equations, boundary conditions and constitutive equations are derived. The case of a Single Walled carbon Nanotube (SWNT) modelled … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 12 May 2014 · 6,930 accessesView PDF Cite
