for dynamic analyses of railway track structures, the algorithm of solution is very important. for estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. for studying the effects of axially beam on the ela...

Abstract Artificial intelligence (AI) is an important part of today’s pervasive computing systems. Still, there no end-to-end system platform that allows to deploy, update, manage and execute AI models in We propose such a this paper. Most importantly, we reuse concepts techniques from twenty years research on how enable runtime adaptation apply it AI. This specify adaptive are able react multi...

Elastic rings are common rotor supporting structure, which have been widely used in aeroengine support system. However, large inertia force and gyroscopic moment may occur during the operation of aeroengine, lead to contact between elastic ring bearing pedestal, then introduce variable stiffness into In this paper, a mathematical model is proposed subsequently verified by comparison with simula...

There is a growing trend of combining human-based computation with machine-based computation to solve complex problems which cannot be answered with machine-based computation alone. From the computing perspective, integrating machine-based computing elements with human-based computing elements and provisioning them under the same model will facilitate the resource elasticity required by complex...

Single-crystal Brillouin spectroscopy measurements have been carried out to 1073 K and ambient pressure to determine the elastic odulus tensor of a natural orthopyroxene, nearly pure Mg end-member (Mg0.994Fe0.002Al0.004)2(Si0.996Al0.004)2O6 orthoenstatite. hree single-crystal specimens with orthogonal crystallographic orientations were prepared for Brillouin measurements to determine ll the sin...

We present the design, implementation, and an evaluation of Elastic Phoenix. Based on the original Phoenix from Stanford, Elastic Phoenix is also a MapReduce implementation for shared-memory systems. The key new feature of Elastic Phoenix is that it supports malleable jobs: the ability add and remove worker processes during the execution of a job. With the original Phoenix, the number of proces...
