Background: Multiple Sclerosis (MS) is the most frequent non-traumatic neurological disease capable of causing disability in young adults. Detection of MS lesions with magnetic resonance imaging (MRI) is the most common technique. However, manual interpretation of vast amounts of data is often tedious and error-prone. Furthermore, changes in lesions are often subtle and extremely unrepresentati...

In this paper, we present a continuous approach to ordering 2D images when compositing. Previous methods for stacking image layers require them to appear in a single (though possibly different) order at every point in the image. Our soft stacking approach removes this restriction – allowing layers to stack as if they were volumes of fog, appearing partially in front of and partially in back of ...

An analytical solution is obtained for the 3D static deflection of variable stiffness composite beams subject to non-uniformly distributed loads. Governing differential equations with coefficients, reflecting spatially properties, are presented in which four degrees freedom fully coupled. The general integral form derived and closed-form expressions using series expansion approximations. a numb...

We combine atomistic calculations and continuum laws to model irradiation-induced vacancy interstitial dislocation loops in ?-zirconium. A comprehensive set of Burgers vectors/stacking sequences the prismatic basal planes, sizes accessible experiments, are studied by Molecular Statics (MS) simulations. Their formation energies structural details determined using two different interatomic potent...

A novel semi analytical method is developed for transient analysis of single-lap adhesive joints with laminated composite adherends subjected to dynamical loads. The presented approach has the capability of choosing arbitrary loadings and boundary conditions. In this model, adherends are assumed to be orthotropic plates that pursuant to the classical lamination theory. Stacking sequences can be...

The principal effects of mass degradation on polymer matrix composites (PMCs) are the decay of mechanical properties such as strength, elongation, and resilience. This degradation is a common problem of the PMCs under thermal cycling conditions. In this article, composite degradation was investigated by measurement of total mass loss (TML) using the Taguchi approach. Thermal cycling tests were ...

in this study, the effect of tensile test temperature (148 to 673 k) on the microstructural evolutions and the mechanicalproperties of high manganese twinning induced plasticity (twip) steel with the chemical composition of fe-31mn-3al-3si (wt. %) was investigated. xrd, sem and tem were used to study the microstructural evolutions.stacking fault energy (sfe) of the alloy was also calculated by ...

In this study, the dynamic stability analysis of laminated composite single-bay and two-bay curved frame structures has been investigated. For purpose, a computer code is written in MATLAB to evaluate natural frequency values, critical buckling load, first unstable regions frames. The effects radii curvature stacking order on static both single two bay arch are Besides, investigated by consider...

This research is aimed at seeing how different stacking sequences and chemical treatments impact the mechanical characteristics of ramie–hemp composites. Hand-lay-up procedures were used to create a blend woven ramie hemp fibers. The was treated with diluted 6% sodium hydroxide (NaOH) solution compare properties preserved unpreserved hybrid According findings, tensile composites are better in t...

Composite materials allow to tailor the elastic properties of a structure. In aeroelasticity, this opens up possibility passively enhance coupled aerostructural characteristics. work, design composite wing is addressed with aim alleviate static and dynamic aeroelastic loads; these two objectives are quantified by root-bending-moment in high load-factor condition deformation amplitude under gust...
