Estimating the Torsional Capacity of Reinforced Concrete Beams Using ANFIS Models [PDF]

Advances in Engineering and Intelligence Systems
Designing or appraising framed concrete buildings exposed to high eccentric loads requires precise reinforced concrete (𝑅𝐶) torsional strength estimates. Unfortunately, semi-empirical formulae still fail to adequately predict the torsional capacity of 𝑅𝐶

Analytic Torsion of Z_2-graded Elliptic Complexes

, 2010
We define analytic torsion of Z_2-graded elliptic complexes as an element in the graded determinant line of the cohomology of the complex, generalizing most of the variants of Ray-Singer analytic torsion in the literature.

Significant differences in femoral torsion values depending on the CT measurement technique

Archives of Orthopaedic and Trauma Surgery, 2016
IntroductionThis study compared the feasibility of six different CT-based measurement techniques for establishing an indication for derotational osteotomy in the cases of patellar instability or femoral fracture.Materials and methodsCT scans of 52 single

Maxwell's field coupled nonminimally to quadratic torsion: Induced axion field and birefringence of the vacuum

, 2003
We consider a possible (parity conserving) interaction between the electromagnetic field $F$ and a torsion field $T^\alpha$ of spacetime. For generic elementary torsion, gauge invariant coupling terms of lowest order fall into two classes that are both ...

Fiber Ring Laser Directional Torsion Sensor with Ultra-Wide Linear Response

Sensors, 2019
In this paper, a comprehensive passive torsion measurement is performed firstly in a 40-cm-long polarization maintaining fiber-based Sagnac interferometer (PMF-SI), and the non-linear torsion response is found and investigated.

Low-energy general relativity with torsion: a systematic derivative expansion

, 2012
We attempt to build systematically the low-energy effective Lagrangian for the Einstein--Cartan formulation of gravity theory that generally includes the torsion field. We list all invariant action terms in certain given order; some of the invariants are

Torsion of a growing shaft

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
The torsion of a shaft by rigid disks is considered. The shaft has the form of circular cylinder. Two rigid disks are attached to its end faces. The process of continuous growth of such shaft under the influence of twisting torques applied to the disks ...
