Doubly Spinning Black Rings [PDF]
Physical Review D, 2006 We study a method to solve stationary axisymmetric vacuum Einstein equations numerically. As an illustration, the five-dimensional doubly spinning black rings that have two independent angular momenta are formulated in a way suitable for fully nonlinear ...

A Charged Doubly Spinning Black Ring [PDF]
Physical Review D, 2008 This paper calculates the general form of a 5d metric when fundamental string and momentum charges are added. This is accomplished using the standard method of boosting and T-dualising a solution to Einstein's equations, where the solution has three ...

A Comparison Study of Yarns Produced by Ring Spinning System, For Native and Foreign Cotton Types [PDF]
Maǧallaẗ Al-Turāṯ wa Al-Taṣmīm, 2021 The garment's end used depends on the fabric properties, whilst the fabric property depends on the properties of the constituent yarn. Therefore, with the diversification of the market, spinners are forced to produce quality yarn.

Stability of feeding cylinder shell under torsion in pneumo-mechanical spinning machines [PDF]
E3S Web of Conferences, 2023 The essence of the pneumo-mechanical spinning method lies in the transformation of the tape into a discrete stream of fibers, in the formation of a wedge-shaped ribbon from this stream in the form of an open end in the groove of the spinning chamber and ...
