Research ArticleOpen accessAll words, across the recordNumerical Investigation of an Industrial Robot Arm Control Problem Using Haar Wavelet SeriesS. Nandhakumar, V. Selladurai, S. SekarProblem statement: An error minimization in robot arm dynamics improves operations and performance of production systems. Many contributions have been made in area of robot dynamics since the earliest study more than two decades, but, a number of researchers are still contributing various principles and new techniques for the best use of robots in reality, especially in the field of … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,045 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSelf-Managed Federation of MQTT Brokers with Dynamic Topology ControlBruno Bevilaqua, Marco Aurélio SpohnThe Message Queuing Telemetry Transport (MQTT) protocol is most used in Internet of Things (IoT) applications. The protocol implements the Publish/Subscribe (P/S) communication model. Publishers are entities providing data to a server (broker), and subscribers are those showing interest in such data. The standard MQTT scenario relies on a single broker, a potential bottleneck, and a single point of failure. … …Journal of Computer Science, Vol. 19, Issue 11 · 18 Oct 2023 · 5,254 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Multiple Tuned Mass Damper for Passive Control of Structures by Cuckoo AlgorithmHamid Jafari Nia, Amir Hossein Heidari, Hamid Reza Babaali, Kaveh Ostad-Ali-AskariAdjustable mass dampers are recently used to reduce seismic vibrations of engineering structures. Function of these types of systems requires a suitable setting of their parameters. In this study, a practical method to design Multiple Tuned Mass Dampers (MTMD) has been proposed to minimize the maximum displacement of roof, acceleration of roof and TMDs displacement to reduce the seismic response … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 16 Jul 2020 · 7,399 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordMEMS Based RF Energy Harvester for Battery-Less Remote Control: A ReviewNoor Hidayah Mohd Yunus, Jahariah Sampe, Jumril Yunas, Alipah PawiThe paper deals with the growing interest of energy harvesting systems due to great development in many new emerging technologies in electronics and telecommunication. The research focuses particularly about rectenna element comprises of antenna, impedance matching and rectifier. The rectenna is applied under Micro-Electromechanical-System (MEMS) technology design use in Radio Frequency (RF) energy harvester. MEMS is a technology of miniaturization … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 19 Feb 2017 · 9,360 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBiomechanically Inspired Shape Memory Effect Machines Driven by Muscle like Acting NiTi AlloysRaffaella Aversa, Francesco Tamburrino, Relly Victoria V. Petrescu et al.The research shows a bioinspired approach to be adopted to design of systems based on Shape Memory Alloys (SMAs), a class of Smart Materials that has in common with muscles the capability to react to an impulse (thermal for SMAs) with a contraction. The biomechanically inspired machine that is discussed in the paper refers to the antagonistic muscles pairs, which … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 24 Nov 2016 · 9,114 accessesView PDFCite
