The problem of a rotating transported thread or yarn occurs in textile applications such as high-speed spinning and unwinding from a cylindrical package. In case of low tension the yarn is known to buckle and fly out under the action of centrifugal forces. The motion initially appears fixed when viewed from a rotating coordinate frame and is known as ballooning (see [1], which also contains ref...

Both biotic and abiotic factors can influence the survival growth of age-0 salmonids. Diseases, such as whirling disease, also affect salmonid demographics population dynamics. Here, we conducted a supplementary analysis evaluated specific stream characteristics that may have been responsible for differences in two disease resistant Rainbow Trout Oncorhynchus mykiss strains observed by Avila et...

This article aims to explore the oscillatory characteristics of a controlled asymmetric rotor system when subjected rub and impact forces between stator. Four electromagnetic poles are used control whirling motion through linear proportional-derivative law. The equations that govern whole dynamics derived including forces. mathematical model is analyzed in two basic steps. Firstly, obtained tre...

Labyrinth seal force estimates are important to the prediction of the stability of turbomachinery. The force prediction methods fall into several categories: experiments, bulk flow analysis, and finite volume analysis. Finite volume analysis can be split into two subcategories: selfdeveloped and commercial. In this research, a commercial computational fluid dynamics (CFD) program called ANSYSCF...

The 13th century Sufi poet Muhammad Rumi [جلال‌الدین محمد رومی] vividly incorporates the image of dance and movement in his lyrics, while Mehlevi Order Islam (popularly known as ‘Whirling Dervishes’) was founded on Rumi’s teachings. Such expressions emotive joy were among favourites my students, when I served Director Inter-Religious Studies at St. Xavier’s College Mumbai. testimony a college s...
