Analysis and Reduction of Time Response in Thermally Activated Shape Memory Alloys

Yves Perriard, Sean Thomas, Yoan René Cyrille Civet, Mario Joe Lehmann, Raphaël Johannes Charles Mottet

This paper aims to study the factors that affect the time response of Shape Memory Alloys (SMA) and establish a method to improve their activation times. In this work, different parameters such as the number, positions and orientation of the perforations o ...

Axisymmetric Tokamak Equilibria computed with a Predefined Safety Factor Profile as CHEASE input

Olivier Sauter, Antoine Pierre Emmanuel Alexis Merle

The CHEASE code, which has been developed at the Swiss Plasma Center, generates an accurate reconstruction of toroidal magnetohydrodynamics equilibria by numerically solving the Grad-Shafranov equation. Having demonstrated its ability to achieve good conve ...

Estimation of dynamically varying displacement derivatives using fringe projection technique

Pramod Rastogi, Sai Siva Gorthi, Rajshekhar Gannavarpu

This paper presents a pseudo Wigner–Ville-distribution-based method in fringe projection for analyzing temporal behavior of the displacement derivative for a continuously deformed object. In the proposed method, a computer generated fringe pattern is proje ...

Local and Global Eulerian Gyrokinetic Simulations of Microturbulence in Realistic Geometry with Applications to the TCV Tokamak

Xavier Lapillonne

In magnetically confined fusion devices, the energy and particle transport is significantly larger than expected from purely collisional processes. This degraded confinement mostly results from small-scale turbulence and prevents from reaching self-sustain ...
