Research ArticleOpen accessIn the keywordsComputation of Irregular Boundary Area by Lacunary Interpolation TechniqueJamal Muhamad AmenProblem statement: Rising up land value and a rapid extension in large town in the world, this in addition to appearance a new technique in applied mathematics especially in interpolation felid during last period encourage engineers and surveyor to search for a new mathematical formula for calculating area of a land. Approach: In this study, (0, 2) lacunary interpolation technique … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 26 Mar 2011 · 8,355 accessesView PDFCite
Research ArticleOpen accessIn the abstract2D Kinematic Quantification of Soil Particles around Growing Plant Root based on Optical MechanicsWenbin Wu, Jian ZhaoThe quantitative kinematic description of the surrounding soil particles during root growth is a technical challenge and biologically important. In this study, a two-dimensional camera-based imaging system was used to observe micro scale interactions between plant roots and soil particles. Maize root tip was imaged during ingress into the soils. This produced a series of two-dimensional images that represent temporal … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 21 Oct 2020 · 6,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractSomething about the Mechanical Moment of InertiaFlorian Ion T. Petrescu, Antonio Apicella, Aversa Raffaella et al.In this study, the relations to determining mass moments of inertia (mechanical) for different mass and mechanical inertia corresponding to geometric shapes, objects and profiles are explored. The formulas for calculating the mass moments of inertia (mechanical) for various bodies (various geometrical forms), to certain major axis indicated (as the axis of calculation) are presented. The total mass M of … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 4 Nov 2016 · 11,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Anthropomorphic Gripping Manipulator: The Analysis of Implementation MethodsIvan Vladimirovich Krechetov, Arkady Alekseevich Skvortsov, Pavel Sergeevich LavrikovThe object of the article is the study of implementation methods for the development of hardware-software engineering solutions in the field of the creation of a universal anthropomorphic gripper. Such technical solutions are intended to enable the adaptation and extensive use of advanced robotic systems in the natural environmental conditions formed by people through equipping them with anthropomorphic universal grippers … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 17 Nov 2015 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Behavior of Tyre Tread BlockK. Sridharan, R. SivaramakrishnanThe Tyre tread pattern is the arrangement of blocks, grooves and voids, sipes and channels designed into the tread to enhance its grip on the road. Tread is the uppermost part of any tyre which contact into the road and it has its own performance towards mileage, traction, low noise and heat built up properties. It would be meaningful to … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 28 Jul 2012 · 9,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractRetrieval of Similar Shapes Under Affine Transform Using Affine Length ParameterizationA. Lakehal, O. El Beqqali, O. Ait ZemzamiProblem statement: In this study, a new descriptor for shape retrieval under affine transformations had been proposed; the affine length parameterization was used in this approach. Approach: The zero crossing of affine curvature was used to extract a descriptor of shapes in database. For each two successive zero crossing points we extract two parameters: the first parameter was a maximal … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Aug 2010 · 7,255 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Two Interacting Localized Defects on the Critical Load for Thin Cylindrical Shells Under Axial CompressionAbdellatif Khamlichi, Jalal El Bahaoui, Larbi El Bakkali et al.Problem statement: Many modern structures are made from thin shells. Design of these elements depends to a large extent on their buckling behavior which is hugely affected by the initial geometric imperfections. Approach: For axially compressed isotropic circular cylindrical shells, axisymmetric localized geometric imperfections were found to reduce severely the buckling strength. Among various axisymmetric shapes of localized defects that … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,065 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer-Aided Design Data Extraction Approach to Identify Product InformationMohamad Faizal Ab. Jabal, Mohd. Shafry Mohd. Rahim, Nur Zuraifah Syazrah Othman, Daut DamanProblem statement: Many approaches have been proposed in previous such as AUTOFEAT algorithm, feature recognition, Intelligent Feature Recognition Methodology (IFRM), a part recognition algorithm and graph theory-based approach in order to solve the integration issue between CAD and CAM. However, there is no direct connection from CAD database and machine database. Therefore, comparison among the approaches has been conducted because … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 7,170 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDegradation of Power Generation Performance due to Effects of Various Ice Shapes and Accretions on Wind Turbine BladesAditya Bagade, Changki Mo, Abdelhamid MazherIn today’s world, green energy has become a key initiative as an alternative energy resource. Wind turbines are widely used to harvest wind energy in seasonal and cold environments. Although efficient, cold weather conditions negatively affects wind turbine operations due to ice formation. Damage from icing is seen on blade-tips when super-cooled water droplets that form in colder environments rapidly … …Energy Research Journal, Vol. 6, Issue 2 · 11 Sep 2015 · 7,815 accessesView PDFCite
