Torsion and gravitation: A new view
(World Scientific Publ Co Pte Ltd, 2004-05-01)
According to the teleparallel equivalent of general relativity, curvature and torsion are two equivalent ways of describing the same gravitational field. Though equivalent, they act differently: curvature yields a geometric ...
System to measure torsion modulus of polymers using the deformation energy method
(Assoc Brasil Polimeros, 2019-01-01)
This paper presents an alternative method to measure the torsion modulus, G, for samples of polymers. We constructed a measurement system with a force sensor (FS) and a rotational movement sensor (RMS) to obtain a relationship ...

Estimation of accidental torsion effects for seismic design of buildings
(1995)
A procedure is developed for including the effects of accidental torsion in seismic design of buildings. It has four steps. First, the ratio between the fundamental frequencies of uncoupled torsional and lateral motions ...

Abelian torsion groups with a countably compact group topology
(ELSEVIER SCIENCE BV, 2010)
Comfort and Remus [W.W. Comfort, D. Remus, Abelian torsion groups with a pseudo-compact group topology, Forum Math. 6 (3) (1994) 323-337] characterized algebraically the Abelian torsion groups that admit a pseudocompact ...
Electrically, Chemically, and Photonically Powered Torsional and Tensile Actuation of Hybrid Carbon Nanotube Yarn Muscles
(Amer Assoc Advancement Science, 2012-11-16)
Artificial muscles are of practical interest, but few types have been commercially exploited. Typical problems include slow response, low strain and force generation, short cycle life, use of electrolytes, and low energy ...
Torsion control in structures isolated with the triple friction pendulum system
(2020)
A parametric study was carried out to investigate the torsional response of structures isolated with the Triple Friction Pendulum (TFP) system with building properties such as uncoupled torsional to lateral frequency ratio, ...
Abordaje fisioterapéutico de anteversion femoral en niños
(2019-01-28)
El ángulo de anteversión del cuello femoral es un factor importante para la estabilidad de la cadera y la marcha en el niño .Es resultado multifactorial de evolución, herencia, desarrollo fetal, intrauterino, posición ...
On the influence of the mode-shapes of a marine propulsion shafting system on the prediction of torsional stresses
(2013-05-13)
Torsional vibration predictions and measurements of a marine propulsion system, which has both damping and a highly flexible coupling, are presented in this paper. Using the conventional approach to stress prediction in ...
