Torsion Discriminance for Stability of Linear Time-Invariant Systems

Mathematics, 2020
This paper extends the former approaches to describe the stability of n-dimensional linear time-invariant systems via the torsion τ ( t ) of the state trajectory.

Preoperative diagnosis of a torsioned accessory spleen

Journal of Medical Ultrasound, 2021
We report a case of a 12-year-old boy with an accessory spleen torsion. He presented with left-sided abdominal pain after trauma. A 4 cm oval mass without contrast enhancement was detected on contrast-enhanced computed tomography (CT), and ultrasound (US)

Torsion units in integral group ring of the Mathieu simple group M22 [PDF]

, 2008
We investigate the possible character values of torsion units of the normalized unit group of the integral group ring of the Mathieu sporadic group M22.

Reinforced and prestressed concrete hollow beams under torsion

Journal of Civil Engineering and Management, 2014
Recently a new rational theoretical model for beams under torsion has been proposed. This model, called Softened Membrane Model for Torsion (SMMT), is able to predict well the global behaviour of reinforced and prestressed concrete solid beams under ...

Minimal inclusions of torsion classes [PDF]

Algebraic Combinatorics, 2017
Let $\Lambda$ be a finite-dimensional associative algebra. The torsion classes of $mod\, \Lambda$ form a lattice under containment, denoted by $tors\, \Lambda$.

A discrete methodology for controlling the sign of curvature and torsion for NURBS [PDF]

, 2009
This paper develops a discrete methodology for approximating the so-called convex domain of a NURBS curve, namely the domain in the ambient space, where a user-specified control point is free to move so that the curvature and torsion retains its sign ...

Zassenhaus conjecture for central extensions of S5 [PDF]

, 2008
We confirm a conjecture of Zassenhaus about rational conjugacy of torsion units in integral group rings for a covering group of the symmetric group S5 and for the general linear group GLð2; 5Þ. The first result, together with others from the literature,

Design, Testing, and Sensitivity Analysis of a Torsional Cyclic Test Adapter

Machines
In this article, a torsional adapter is designed and evaluated through the comparison of analytical, numerical, and experimental tools. The adapter converts a conventional tension–compression test machine for cyclic loading to a modified application of ...

Acute torsion of the gallbladder:a report of two cases [PDF]

Journal of Kerman University of Medical Sciences, 1996
gallbladder torsion is a rare surgical emergency that can not be differentiated from acute cholecystitis.this condition occurs primarily in elderly women,although it may be encountered in early adulthood of both sexes.the anatomic background is based on ...

Delamination of multilayered non-linear elastic shafts in torsion [PDF]

FME Transactions, 2020
Delamination cracks in multilayered circular shafts loaded in torsion are analyzed in terms of the strain energy release rate. It is assumed that the material in each layer has non-linear mechanical behaviour that is treated by the Ramberg-Osgood ...
