MSTor is a computer program for calculating gas-phase molecular partition functions and thermodynamic functions (standard state energy, enthalpy, entropy, free energy, and heat capacity at constant pressure) as functions of temperature by the multistructural approximation with torsional anharmonicity (MS-T). The MS-T approximation accounts for the coupling of torsions to one another and to over...

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...

Recent investigations have focused on the use of active phase imbalance schemes using series connected FACTS devices for subsynchronous resonance (SSR) and power swing damping. This paper compares the effectiveness of TCSC and SSSC based single phase compensation schemes with the corresponding three phase schemes. Controllability of swing modes as well as torsional modes is compared by using a ...

Wet friction clutches play a critical role in vehicles equipped with automatic transmissions. It is unavoidable that they progressively degrade and eventually break down while the vehicles are under operational condition. To avoid unexpected failures, a proper condition monitoring tool extended with a lifetime prediction method should be implemented. In order to achieve this, appropriate parame...

Mechanical motion of photonic devices driven by optical forces provides a profound means of coupling between optical fields. The current focus of these optomechanical effects has been on cavity optomechanics systems in which co-localized optical and mechanical modes interact strongly to enable wave mixing between photons and phonons, and backaction cooling of mechanical modes. Alternatively, ex...

The calculation of torsional oscillations in crankshaft-propeller systems is carried out by a new method which reduces considerably the numerical work in the case of in-line engines. The theory is briefly outlined and the reader is referred to another publication of the author for further details. Three applications follow. In the first, all six natural frequencies and the corresponding modes a...

In this paper, the propagation of time-harmonic torsional waves in composite elastic cylinders is investigated. An imperfect interface is considered where tractions are continuous across the interface and the displacement jump is proportional to the stress acting on the interface. A frequency equation is derived for the rod and dispersion curves of normalized frequency as a function of normaliz...
