Research ArticleOpen accessIn the abstractContributions to the Stirling Engine StudyFlorian Ion Tiberiu PetrescuIn the process of transforming thermal energy into mechanical work, among the known thermal machines, the Stirling engine is the one that can achieve the highest yield (theoretically up to the maximum yield of the Carnot cycle), although in practice it is reduced by the properties of gas and materials used such as friction coefficient, thermal conductivity, melting point, breaking … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 10,172 accessesView PDFCite
Review ArticleOpen accessIn the abstractBiomechanically Inspired Machines, Driven by Muscle Like Acting NiTi AlloysAntonio Apicella, Raffaella Aversa, Florian Ion Tiberiu PetrescuThe Shape of the Memory Alloy (SMA) is a very promising class of metallic materials with interesting non-linear properties such as Pseudo-Elasticity (PE), memory (MEM) and damping capacity due to high mechanical hysteresis and internal friction. Research shows a bioinventory approach to Shape Memory Alloy (SMA) design, a class of intelligent materials capable of reacting to a pulse (thermal for … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 23 May 2018 · 8,279 accessesView PDFCite

Some parameters like calculation of area, pixel value statistics, distances and angles measurements, edge detection, such as the circularity, ferret angle, solidity and perimeter, average area and the percentage area was examined. Federated grain count was … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 12 Mar 2018 · 7,571 accessesView PDFCite
Case ReportOpen accessIn the abstractSimulation of Stone Column Ground Improvement (Comparison between Axisymmetric and Plane Strain)Maryam Gaber, Anuar Kasa, Norinah Abdul-Rahman, Jamal AlsharefMost of the numerical studies on stone columns are based on the unit cell concept. However, the impact of interactions between adjacent columns and between the columns and the surrounding soil has not been investigated thoroughly. In this study, the finite element software, PLAXIS-2D-V8.2, was used to simulate a stone column as a unit cell and as a plane strain … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 16 Jan 2018 · 8,152 accessesView PDFCite
