In this paper, linear stability analysis of non-prismatic beam resting on uniform Winkler-Pasternak elastic foundation is carried out based on Eringen's non-local elasticity theory. In the context of small displacement, the governing differential equation and the related boundary conditions are obtained via the energy principle. It is also assumed that the width of rectangle cross-section varie...

Abstract In this study, modeling of discharge was performed in compound open channels with non-prismatic floodplains (CCNPF) using soft computation models including multivariate adaptive regression splines (MARS) and group method data handling (GMDH), then their results were compared the multilayer perceptron neural networks (MLPNN). addition to total discharge, separation between floodplain ma...

the relations of fibrolite-biotite are discussed by presenting data from the ardara aureole, nw ireland. biotite-fibrolite intergrowths are developed in all three aureole zones including: the outer kyanite-bearing andalusite zone, the middle kyanite-free andalusite zone and the inner prismatic sillimanite zone. a strain-assisted mechanism is proposed for the fibrolitisation of biotite in the ar...

Previous studies have identified sensitive periods for the developing barn owl during which visual experience has a powerful influence on the calibration of sound localization behavior. Here we investigated neural correlates of these sensitive periods by assessing developmental changes in the capacity of visual experience to alter the map of auditory space in the optic tectum of the barn owl. W...

The solution of the Stokes problem in three-dimensional domains with edges has anisotropic singular behaviour which is treated numerically by using anisotropic nite element meshes. The velocity is approximated by Crouzeix-Raviart (non-conforming P 1) elements and the pressure by piecewise constants. This method is stable for general meshes (without minimal or maximal angle condition). The inter...

This paper presents a novel 4 dofs (3T-1R) parallel actuatedly redundant mechanism and its workspace analysis, based on a performance index involving velocity and force capabilities. The robot is capable of performing a half-turn about the z axis. Moreover, having all of its prismatic actuators along one direction; the x motion is independentonly limited by the stroke of the prismatic actuators...

The formation of prismatic dislocation loops is an important factor leading to radiation damage of metals. However, the formation mechanism and the size of the smallest stable loop has remained unclear. In this Rapid Communication, we use electronic structure calculations with millions of atoms to address this problem in aluminum. Our results show that there is a cascade of larger and larger va...

One of the main bottlenecks in natural language processing is the lack of a comprehensive lexicalized relation resource that contains fine grained knowledge on predicates. In this paper, we present PRISMATIC, a large scale lexicalized relation resource that is automatically created over 30 gb of text. Specifically, we describe what kind of information is collected in PRISMATIC and how it compar...

IMPORTANCE Myopia is a significant public health problem, making it important to determine whether a bifocal spectacle treatment involving near prism slows myopia progression in children. OBJECTIVE To determine whether bifocal and prismatic bifocal spectacles control myopia in children with high rates of myopia progression and to assess whether the treatment effect is dependent on the lag of ...
