Research ArticleOpen accessIn the abstractSimultaneous Presence of Growth and Remodeling in the Bone Adaptation TheorySeyyed Amir Hooshiar Ahmedi, Gholamreza Rouhi, Hamidreza Katouzian, Seyyed Ali Hooshiar AhmediMechanical forces acting on bone during growth affect their final shape and strength. Mechanoregulation of bone growth is maybe recognized in embryogenesis, and also in the adaptation of the adult skeleton to changes in mechanical loading. By combining equations describing bone remodeling and growth with an iterative finite element analysis, a computational model to simulate the simultaneous effects of bone … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Mechanical Characteristics of Inverter-induction Motor Drive SystemHussein Sarhan, Rateb IssaAn inverter-three-phase squirrel-cage induction motor drive system with improved mechanical characteristics is presented. The proposed system provides mechanical characteristics with constant maximum torque or increased maximum torque and reduced slip speed at frequencies below the nominal frequency. The control algorithm is based on the constant volts per hertz principle using two improvement techniques: keeping maximum torque constant or keeping magnetic … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 7,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractECONOMIC ANALYSIS OF PROCESS INNOVATIONS IN THE MANAGEMENT OF OLIVE FARMSRiccardo Testa, Anna Maria Di Trapani, Filippo Sgroi, Salvatore TudiscaWithin a business enterprise, process innovations lead to reduced production costs and to increased profit margins. In this study, we shall examine an olive farm that operates in a perfectly competitive market that has introduced a process innovation so as to contain labour costs and therefore production costs. So, the paper aimed at comparing economic competitiveness of an olive farm … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 4 Jul 2014 · 7,161 accessesView PDFCite
