Research ArticleOpen accessAll words, across the recordSmart-Factory: Optimization and Process Control of Composite Centrifuged PipesRaffaella Aversa, Relly Victoria V. Petrescu, Florian Ion T. Petrescu, Antonio ApicellaProcess optimization strategies and intelligent control algorithms for an industrial centrifugal pipe production are presented. The chemo-rheological and thermo-kinetic features of the polymerization of unsaturated polyester based composites are analyzed by means of a mathematical model that uses the heat transfer and generation properties of polymerizable systems. The evolution of the system temperature, viscosity and degree of cure profiles in … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 29 Nov 2016 · 8,906 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Study of Clinical Behavior in Intensive Care UnitGilly SmithProblem statement: In order to support the needs of the staff working in discrete areas of nursing, the attitudes, behaviors and needs of the group must first be articulated. Unfortunately, there has been little research conducted to understand the culture of what it is that health care workers think and feel and why they make the choices they do in … …International Journal of Research in Nursing, Vol. 1, Issue 1 · 30 Jun 2010 · 8,674 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNonlinear Control of Variable wind Speed Conversion System Based on a Squirrel Cage Induction Generator (SCIG)Abouobaida HassanThis study presents a control strategy for a Squirrel Cage Induction Generator (SCIG)-based wind energy conversion system. Control strategies of the AC/DC/AC converter is presented along with the mathematical modeling of the employed configuration. The maximum power point extraction of the wind turbine is addressed along with the proposed strategy. The backstepping approach is introduced to control the generator speed … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 25 Jun 2015 · 7,565 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part I: Fluidization Behavior and Characteristic VelocitiesV. S. Chok, A. Gorin, H. B. ChuaProblem statement: Palm shell on its original state cannot be fluidized solely. However, mixing palm shell with a second fluidizable material can facilitate proper fluidization. Approach: The minimum and complete fluidization velocity (Umf and Ucf) for sand/palm shell binary mixtures had been studied in a partitioned reactor known as Compartmented Fluidized Bed Gasifier (CFBG). The pilot scale reactor ID is … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,214 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordProduction and Roles of Glial Tissue Inhibitor of Metalloproteinases-1 in Human Immunodeficiency Virus-1-Associated Dementia Neuroinflammation: A ReviewC. Chao, A. GhorpadeProblem statement: Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) and its cognate targets, the Matrix Metalloproteinases (MMPs), were differentially expressed in human brain samples with or without HIV-1 infection or HIV-1 Encephalitis (HIVE). Approach: A through literature review demonstrated that cell culture models of Central Nervous System (CNS) cell types had been used to illustrate the intricate temporal patterns of TIMP-1/MMP expression, … …American Journal of Infectious Diseases, Vol. 5, Issue 4 · 31 Dec 2009 · 6,953 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of Information Overload on Brazilian E-ConsumersRafael Lucian, Salomão Alencar de FariasProblem statement: E-commerce is a reality; Companies must consider this media as an important trade channel without distances between products and consumers. A key issue of e-commerce is how companies are disclosing information to its customers. This study aims to measure if there is relationship between the information overload in the virtual environment and the response of satisfaction and confusion … …American Journal of Economics and Business Administration, Vol. 1, Issue 1 · 31 Mar 2009 · 7,737 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordImpact Behavior of High Strength Concrete Slabs with Pozzolana as Coarse AggregateMahmoud B.A. Alhasanat, Arabi N. Al QadiThis research goal is the adding of pozzolana as rough aggregate in concrete. Pozzolans of Jabl Onyzh have been described as the major supply from Jordan. It is often used in the place of a conservative aggregate in frivolous concrete. A practical examination was carried out on the resistance of Pozzolana Lightweight Concrete (PLWC) with diverse ratios (35 and 50%) … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 14 Jun 2016 · 7,121 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFactors Affecting Chemo-physical and Rheological Behaviour of Zr44-Ti11-Cu10-Ni10-Be25 Metal Glassy Alloy Supercooled LiquidsApicella Antonio, Aversa RaffaellaSegregation by selective cold crystallizations and glass transition changes in Zr44-Ti11-Cu10-Ni10-Be25 metal supercooled metastable liquid annealed at different temperatures have been theoretically correlated to melt viscosity modifications. Crystallization behavior has been found to be principally related to the high mobility and smaller Be, Cu and Ni atoms. Multiple exothermal peaks in isothermal DSC annealing’s have been observed in these bulk … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,142 accessesView PDFCite
