Research ArticleOpen accessIn the abstractAnalysis and Synthesis of Mechanisms with Bars and Gears Used in Robots and ManipulatorsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Bars and gears are used everywhere today, but a wide range of uses is robotics and mechatronics. Since ancient times, automations and mechanization have been used with mechanisms consisting of chains of bars and gears. These were obviously used for the purpose of transmitting the movement and its transformation, that is to say, as a mechanical transmission. Gear and bar … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 20 Dec 2017 · 7,052 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnthropomorphic Solid Structures n-R KinematicsRelly Victoria V. Petrescu, Raffaella Aversa, Bilal Akash et al.This paper presents and treats (in an original way) the specific elements of the structures of robotic solid mobile anthropomorphic type. Are "placed on the wallpaper", the geometry and kinematics of the anthropomorphic robotic solid systems, in an original vision of the authors. One presents the inverse kinematics of anthropomorphic systems, with mechanical elements and points: Geometry, cinematic, positions, displacements, … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 30 Mar 2017 · 7,775 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization of Clustering Time by a Group of Autonomous Robots Making Use of an Exclusive Multi-MarkingMohamed Rida Abdessemed, Kamel Khoualdi, Azeddine BilamiProblem statement: For solving complex issues, the current tendency goes towards the swarms behaviors, realized on a basis of collective interactions, which results from a cooperative work favoring exchanges between individuals of a same group at microscopic level and allowing the emergence of complex collective behaviors at macroscopic level. Many models were inspired by these attitudes to find simple rules, … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,890 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDynamic Elements at MP3RRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.Mechatronic robotic systems are today widely used worldwide to ease human work, but especially where work is dangerous, in toxic, radioactive, chemical, explosive atmospheres, without air such as underwater or in the cosmos, or in places hard to reach the man. Robots can take the tedious repetitive work under any circumstances and they can perform a difficult operation for a … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 23 Nov 2017 · 7,566 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Variable Neighborhood Search Algorithm for Assigning Cells to Switches in Wireless NetworksMatthieu Andr, Gilles Pesant, Samuel PierreThe problem of assigning cells to switches in wireless networks consists of minimizing the total operating cost, that is, the cost of linking cells to switches and the cost of handover from one cell to another, by taking into account factors such as network topology, switch capacity and traffic load in the entire network. Such a problem is well known … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,748 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Overview of Direction-of-Arrival Estimation using an Antenna Array with Four ElementsLotfi Osman, Imen Sfar, Ali GharsallahThe Direction-of-Arrival (DOA) estimation techniques using antenna arrays are applied in large areas of research fields and have received great attention in literature. Mobile communication, Sonar and Radar are just some examples among a large number of possible applications. For example, in military application, it is very important to recognize the direction of any threat. Another example of commercial application … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 14 Dec 2012 · 7,777 accessesView PDF Cite
