Research ArticleOpen accessIn the keywordsApplying the Holistic Approach to the Physical Sciences and Engineering SystemsJoseph Z. Ben-AsherThe holistic approach is applied to several examples from the field of physics, engineering and systems engineering and its benefits are demonstrated. In all examples a holistic picture is used and studied while ignoring the various details of the discussed problems. Optimal control and optimal estimation approachs are used in the engineering examples. The results show that the holistic approach … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 6,915 accessesView PDFCite
Research ArticleOpen accessIn the keywordsArtificial Neural Network Based Rotor Capacitive Reactance Control for Energy Efficient Wound Rotor Induction MotorK. Ranjith Kumar, S. Palaniswami, K. Siva KumarProblem statement: The Rotor reactance control by inclusion of external capacitance in the rotor circuit has been in recent research for improving the performances of Wound Rotor Induction Motor (WRIM). The rotor capacitive reactance is adjusted such that for any desired load torque the efficiency of the WRIM is maximized. The rotor external capacitance can be controlled using a dynamic … …Journal of Computer Science, Vol. 8, Issue 7 · 26 May 2012 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTuning of a Proportional-Integral-Derivative Controller using Multi-Objective Non Dominated Sorting Particle Swarm Optimization Applied to pH Control in Continuous Stirred Tank ReactorC. Agees Kumar, N. Kesavan NairProblem statement: Most of the control engineering problems are characterized by several, contradicting, conflicting objectives, which have to be satisfied simultaneously. Two widely used methods for finding the optimal solution to such problems are aggregating to a single criterion and using Pareto-optimal solutions. Approach: Non-Dominated Sorting Particle Swarm Optimization algorithm (NSPSO) based approach is used in the design of multiobjective … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 6,793 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Multi-Objective HPSO Algorithm Approach for Optimally Location of UPFC in Deregulated Power SystemsSeyed Abbas Taher, Seyed Mohammad Hadi TabeiThis paper presents the application of hybrid particle swarm optimization technique to find optimal location of unified power flow controller to achieve optimal power flow. Objective function in the OPF, that is to be minimized, are the overall cost functions, which include the total active and reactive production cost function of the generators and installation cost of UPFCs. The OPF … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,979 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Solar Tracking System by Using Digital Solar Position SensorSingthong PattanasethanonProblem statement: An optimal control on two axes and design for solar tracker which called altitude and azimuth is challenge. Approach: The phototransistor with the shade that blocks the screen was employed as a detector of solar beam radiation. The height of the screen determined the sensitivity operation or period of tracking in this solar tracker. The phototransistor is particularly … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 10,179 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe 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
Research ArticleOpen accessIn the keywordsDYNAMIC MODELING AND GAIN SCHEDULING CONTROL OF A CHIILLED WATER COOLING SYSTEMJun Liu, M. ZaheeruddinA dynamic model of a Chilled Water (ChW) cooling system with a stratified ChW tank was developed. A PI-based Gain Scheduling (GS) control strategy was designed to improve thermal performance of the chiller system. Five different operation strategies were simulated and the energy consumption and cost of operating the system under full load and partial load conditions were compared.

Research ArticleOpen accessIn the abstractEffects of Wheat Bran, EM Bacteria, Ammonium Nitrate and Fungal Additives on Fermentation and Forage Quality of Rice Straw SilageBin Yang, Jiahuan Liu, Dongmei Ma et al.The global ruminant industry is constrained by a persistent shortage of high-quality roughage, thus rendering the bioconversion of agricultural residues, such as rice straw, a critical priority. Nevertheless, the high lignification, silicification, and nitrogen deficiency of rice straw pose significant biological barriers to traditional ensiling. This study investigated the impact of various additives on rice straw silage quality.
