Research ArticleOpen accessIn the abstractSome Aspects of the Structure of Planar MechanismsRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The machine is a technical system made up of distinct kinematic component parts (called kinematic elements) which, following the imprinting of movements imposed on an element or elements (considered as leading elements), cause movements to all other kinematic elements in order to execute a useful mechanical thing, or transforming some form of energy into mechanical energy. It follows from the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 8 Feb 2018 · 8,025 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Survey of Graph Based Complex Brain Network Analysis Using Functional and Diffusional MRIMd Rafiqul Islam, Xiaoxia Yin, Anwaar Ulhaq et al.The brain network is the function of a structurally and functionally organized complex system. Its structure and activity analysis is one of the most significant challenges. The graph based techniques of brain complex networks have been successfully used in various types of image and medical data analysis. In this survey paper, we focus on a comprehensive study of the analytical … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 8 Jan 2018 · 9,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent Stage in the Field of Mechanisms with Gears and RodsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The development and diversification of machines and mechanisms with applications in all fields require new scientific researches for the systematization and improvement of existing mechanical systems by creating new mechanisms adapted to modern requirements, which involve increasingly complex topological structures. The modern industry, the practice of designing and building machinery is increasingly based on the results of scientific and applied … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 13 Dec 2017 · 6,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractInverse Kinematics at the Anthropomorphic Robots, by a Trigonometric MethodRelly Victoria V. Petrescu, Raffaella Aversa, Bilal Akash et al.A robot is a machine especially programmable one through a computer capable of performing a complex series of actions in the automatic mode. Robots may be guided by a control device or external control may be incorporated in the inside. Robots can be built to take human form, but most robots are machines designed to perform a task without taking … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 27 Apr 2017 · 8,822 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerturbation Iteration Transform Method for the Solution of Newell-Whitehead-Segel Model EquationsGrace O. Akinlabi, Sunday O. EdekiIn this study, a computational method referred to as Perturbation Iteration Transform Method (PITM), which is a combination of the conventional Laplace Transform Method (LTM) and the Perturbation Iteration Algorithm (PIA) is applied for the solution of Newell-Whitehead-Segel Equations (NWSEs). Three unique examples are considered and the results obtained are compared with their exact solutions graphically. Also, the results agree … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 20 Feb 2017 · 6,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Fractional Order Integro-Differential Equations by using Chebyshev Neural NetworkSarkhosh S. Chaharborj, Shahriar S. Chaharborj, Yaghoub MahmoudiRecently fractional integro-differential equations have been proposed for the modeling of many complex systems. Simulation of these equations requires the development of suitable numerical methods. This paper is devoted to finding the numerical solution of some classes of fractional integro-differential equations by employing the Chebyshev Neural Network (ChNN). The accuracy of proposed method is shown by comparing the numerical results … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 11 Feb 2017 · 7,406 accessesView PDFCite

Review ArticleOpen accessIn the abstractCoenzyme Q10 and its Effective SourcesHamideh Vaghari, Roholah Vaghari, Hoda Jafarizadeh-Malmiri, Aydin BerenjianCoenzyme Q10 (2,3-dimethoxy, 5-methyl, 6-decaprenyl benzoquinone, CoQ10) is naturally present in many organisms. It has key roles in several biochemical pathways. CoQ10, as an electron and proton carrier for energy coupling leads to Adenosine Triphosphate (ATP) formation. Furthermore, in medicine, the pharmacological use of CoQ10 has attracted more attention due to its benefits in treating cardiovascular and degenerative neurologic diseases. … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 10 Oct 2016 · 9,283 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Tunnel-Support Interaction Through a Probabilistic ApproachPierpaolo OresteThe analysis of the behavior of a tunnel requires the evaluation of numerous parameters, relative to the ground and the support structure and which are generally only known with a certain degree of approximation. The uncertainty of these parameters is reflected on the results of the calculation, that is, on the state of stress in the support structure. In order … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 3 Apr 2015 · 6,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Determination of the Tunnel Structure Loads Through the Analysis of the Interaction between the Void and the Support Using the Convergence-Confinement MethodPierpaolo OresteThe evaluation of the load acting on a tunnel support is of fundamental importance for the correct dimensioning of the structure when analytical calculation methods are used. The load acting on the support depends on various factors and for this reason its evaluation can appear somewhat complex. One way of evaluating the load acting on a support is to use … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 6,812 accessesView PDFCite
