The viscoelastic response of a material offers an alternative method for analyzing its microstructure, phase transformations and fatigue behaviour. In this work, the viscoelastic properties of commercial aluminium alloy (AA) 7075-T6 are studied with a Dynamic-Mechanical Analyzer (DMA), and results are combined with Transmission Electron Microscopy (TEM) and Differential Scanning Calorimetry (DS...

in order to determinate appropriate stability parameters, six statistics were studied for flower yield stability of 35 rosa damascena landraces in 8 locations over two years (2007-8) in iran, using a randomized complete blocks design with 3 replications. a positive correlation between environmental variance (s2) and flower yield suggested that only low yield landraces develop a similar phenotyp...

The mixing process of electrode-slurry plays an important role in the electrode performance lithium-ion batteries (LIBs). dispersion state conductive materials, such as acetylene black (AB), directly influences electronic conductivity composite electrodes. In this study, relation between and internal resistance was investigated combination with characterization electrode-slurries by rheological...

In this work dynamic recrystallization behavior of AISI 403 martensitic stainless steel was studied using hot compression tests over temperature range of 900 C -1200 C and strain rate range of 0.001 s-1 - 1 s-1. The obtained flow curves showed that the hot compression behavior of the alloy is controlled by dynamic recrystallization. The flow stress and strain corresponding to the critical, pe...

LVM is a method of allocating disk space on a disk storage devices. Which is more flexible than conventional ones. Logical Volume Manager can usually stripe, mirror or otherwise combine disk partitions to bigger virtual partitions which can be easily moved, resized or manipulated in different ways while in use. Volume Management is one form of disk storage virtualization used in Operating Syste...

Wave propagation in unbounded layered media with a new formulation of Axisymmetric Scaled Boundary Finite Element Method (AXI-SBFEM) is derived. Dividing the general three-dimensional unbounded domain into a number of independent two-dimensional ones, the problem could be solved by a significant reduction in required storage and computational time. The equations of the corresponding Axisymmetri...

The growth of a two-phase cloud of a liquid fuel in a stagnant atmosphere is studied using computational fluid dynamic techniques. In order to predict the danger and hazard of such cloud in open atmosphere it is very important to determine the fuel concentration in the cloud, especially in the far field region from the fuel reservoir. The results show that with omission of droplets break up...
