Research ArticleOpen accessEvery word in the titleDetermining Potential Sites for Runoff Water Harvesting using Remote Sensing and Geographic Information Systems-Based Modeling in SinaiHossam H. Elewa, Atef A. Qaddah, Ayman A. El-FeelProblem statement: Sinai is increasingly suffering from an overwhelming water crisis. Runoff Water Harvesting (RWH) could be a solution for this problem. The determined promising drainage basins for RWH could be used by the decision makers to propose appropriate controlling systems to overcome the problem of water scarcity and for implementing runoff farming and rain-fed agriculture. Approach: Remote sensing, geographic … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 15 Feb 2012 · 8,488 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContribution of Integrated Management Systems to University Management: Case Study of the Federal University of Rio Grande Do NorteLucas A.B.D Oliveira, Natalia V.C.D Vasconcelos, Fernanda C.B.P Queiroz et al.Problem statement: The Higher Education Institutions (IHL) have intensified process of introducing undergraduate and graduate courses to more remote regions, which expanded the scope of what these institutions and allowed the formation of population of these regions. This expansion (whether by on-campus or distance learning) presents new challenges for university management and integration of the players involved in this process. … …Journal of Social Sciences, Vol. 7, Issue 3 · 18 Jul 2011 · 7,795 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModel Predictive Approach to Precision Contouring Control for Feed Drive SystemsM.A. El Khalick, N. UchyiamaProblem statement: High precision machining requires high capability of multi-axis feed drive systems to follow specified contour accurately. Although each feed drive axis is controlled independently in many industrial applications such as X-Y tables and Computer Numerical Control (CNC) machines, machining precision is evaluated by error components orthogonal to desired contour curve. Contouring controller design is required for precision machining, … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,314 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLoad Balancing of Distributed Systems Based on Multiple Ant Colonies OptimizationAl-Dahoud Ali, Mohamed A. Belal, Moh’d Belal Al-ZoubiProblem statement: Ant Colony Optimization (ACO) provides a meta-heuristic optimization tool and collective intelligence model to several applications such as routing and load balancing. A lot of work found in the literature on using ACO in load balancing. However, as far as our knowledge, there was no work relating load balancing in distributed systems with ACO. Approach: In this study, … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,213 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Dynamic Resource Synchronizer Mutual Exclusion Algorithm for Wired/Wireless Distributed SystemsAhmed Sharieh, Mariam Itriq, Wafa DbabatA mobile host has small memory, relatively slow processor, low power batteries, and communicate over low bandwidth wireless communication links. Existing mutual exclusion algorithms for distributed systems are not enough for mobile systems because of several limitations. In this study, a mutual exclusion algorithm that is more suitable for mobile computer systems is developed. The algorithm tends to minimize the … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,163 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA BI-RADS Based Expert Systems for the Diagnoses of Breast DiseasesUmi Kalthum Ngah, Shalihatun Azlin Aziz, Mohd. Ezane Aziz et al.We proposed an expert system based on the interpretation of mammographic and ultrasound images that may be used by expert and non-expert doctors in the interpretation and classifying of patient cases. The expert system software consists of a mammographic (MAMMEX) and breast ultrasound (SOUNDEX) medical expert systems which may be used to deduce cases according to the Breast Imaging Recording … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,434 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdaptive Control of Networked Systems in the Presence of Bounded DisturbancesA. H. Tahoun, Fang Hua-JingThe insertion of data network in the feedback adaptive control loops makes the analysis and design of networked control systems more complex than traditional control systems. This paper addresses the adaptive stabilization problem of linear time-invariant networked control systems when the measurements of the plant states are corrupted by bounded disturbances. The case of state feedback is treated in which … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,542 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEfficiency of Hybrid MPPT Techniques Based on ANN and PSO for Photovoltaic Systems under Partially Shading ConditionsMax Tatsuhiko Mitsuya, Anderson Alvarenga de Moura MenesesHybrid Maximum Power Point Tracking (MPPT) algorithms have been investigated as an alternative to improve the performance of conventional MPPT, such as Perturb and Observe (P&O), Incremental Conductance (InC) and Hill Climbing (HC) in Photovoltaic (PV) systems under Partially Shading Co+ndition (PSC). In the present article, Artificial Neural Network (ANN) and Particle Swarm Optimization (PSO) hybridized with P&O algorithm for … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 3 Oct 2019 · 8,892 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreliminary Experimental and Finite-Element Numerical Assessment of the Structural Performance of SMA-Reinforced GFRP SystemsFilipe Amarante dos Santos, Chiara BedonIn this study, the feasibility and potentiality of a novel design concept is explored by means of small scale experimental tests and Finite-Element numerical simulation. Taking advantage of the intrinsic potentiality of Shape-Memory Alloys wires able to work as adaptive actuators when subjected to joule heating, a 'smart-GFRP' concept consisting in Glass-Fiber-Reinforced-Polymer (GFRP) structural members with a SMA reinforcement is … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,298 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCASE STUDY OF THE OPTIMIZING THE AUTOMOTIVE MANUFACTURING SYSTEMS EFFICIENCY VIA APPLYING NEW METHOD OF SCHEDULINGSeyedehfarzaneh Nojabaei, Matthew FranchettiEfficiency is becoming a pivotal aspect in each manufacturing system and scheduling plays a crucial role in sustaining it. The applicability of distributed computing to coordinate and execute jobs has been investigated in the past literature. Moreover, it is significant that even for sensitive industrial systems the only criterion of allocating jobs to appropriate machines is the FIFO policy.
