Conference on Lasers and Electro-Optics, 2016 A novel torsion sensor based on a phase-shifted fiber Bragg grating inscribed by the line-by-line technique in a standard single-mode fiber with a femtosecond laser is demonstrated. It is the smallest torsion sensor ever reported.

Advanced Engineering Materials, EarlyView.This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Behaviour of steel-reinforced concrete columns under combined torsion based on ABAQUS FEA
, 2020 A computational model for studying the mechanical performance of steel-concrete columns under combined torsion is established via ABAQUS. The model is validated by experimental results. Through numerical simulations, the influence of the axial load ratio,

The Dade group of a fusion system. [PDF]
, 2009 We define the notion of the Dade group of a fusion system and show that some of the gluing and detection results for Dade groups of finite p-groups due to Bouc and Thévenaz in [S. Bouc and J. Thévenaz. Gluing torsion endo-permutation modules. (Preprint.)]

Analytic Torsion and R-Torsion for Unimodular Representations [PDF]
Journal of the American Mathematical Society, 1993 Let \(M^ n\) be a closed manifold, \(\rho: \pi_ 1(M) \to O_ N\) or \(U_ N\) an acyclic orthogonal or unitary representation. \(\rho\) induces a flat vector bundle \(E_{\rho}\) over \(M\). Then the Reidemeister torsion \(\tau_ M(\rho)\) is well defined. Endowing \(M^ n\) with a Riemannian metric \(g\), the analytic torsion \(T_ M(\rho)\) is defined.

Advanced Engineering Materials, EarlyView.Molecular dynamics is used to investigate structure refinement during severe plastic deformation. The results show similitude with experimental data. Molecular dynamics simulations of severe plastic deformation of monocrystalline and polycrystalline samples by multiaxial compression of aluminum are carried out.

On The Holonomy of Connections with Skew-Symmetric Torsion
, 2003 We investigate the holonomy group of a linear metric connection with skew-symmetric torsion. In case of the euclidian space and a constant torsion form this group is always semisimple.

Rib-lifting method for retraction of the low-lying costal arch in laparoscopic cholecystectomy of gallbladder torsion with kyphoscoliosis [PDF]
, 2009 Gallbladder torsion is a rare entity. Recently, laparoscopic cholecystectomy has become accepted as a standard operation for gallbladder torsion. Unfortunately, kyphoscoliosis is a risk factor of gallbladder torsion, and kyphoscoliosis results in a low ...

SIMPLE METHODOLOGY FOR CALCULATING THE CONSTANTS OF GAROFALO EQUATION
Acta Metallurgica Slovaca, 2017 The examination of the high temperature plastic properties of metallic materials was realised by the torsion plastometer SETARAM or by the compression plastometer DIL805A/D. The brass CuZn30 was used as the test material.
