This article investigates the flexural response of cantilevered top chord extensions open web steel joists used in building structures. Currently, no design guidance is available to assess bending capacity these members with consideration local and lateral-torsional buckling failure modes. The objective study was develop a numerical finite element model capable predicting behaviour 13 joist tes...

Bowing a string with a non-zero radius exerts a torque, which excites torsional waves. In general, torsional standing waves have higher fundamental frequencies than do transverse standing waves, and there is generally no harmonic relationship between them. Although torsional waves have little direct acoustic effect, the motion of the bow-string contact depends on the sum of the transverse speed...

Rapid eye movements include saccades and quick phases of nystagmus and may have components around all three axes of ocular rotation: horizontal, vertical, and torsional. In this study, we recorded horizontal, vertical, and torsional eye movements in normal subjects with their heads upright and stationary. We asked how the eyes are brought back to Listing's plane after they are displaced from it...

Elastic stability of ring and stringer-stiffened cylindrical shells under axial, internal and external pressures is studied using Ritz method. The stiffeners are rings, stringers and their different arrangements at the inner and outer surfaces of the shell. Critical buckling loads are obtained using Ritz method. It has been found that the cylindrical shells with outside rings are more stable th...

Clustered architectures which intend to process data within a localized PE are one of the approaches to increase the performance under the difficulties of the wire delay problems. The performance of the clustered architecture depends on the implemented instruction steering scheme. Existing steering schemes insert inter-PE communications to achieve load balance among PEs. These insertions delay ...

Computational algorithm for the solution of 2D and 3D dynamic problems of the Cosserat elasticity theory using multiprocessor computer systems is worked out. The algorithm is based on the two-cyclic splitting method with respect to the spatial variables in combination with the explicit monotone finite-difference ENO–scheme for solving 1D problems adapted for the calculation of discontinuities. ...
