The experimental results of the use of a liquid lithium limiter on FTU are presented. To avoid droplet generation by JxB forces we have adopted a limiter with a capillary porous system configuration. Lithization of the vacuum vessel is performed by exposing lithium limiter to the plasma boundary for three subsequent plasma discharges after that it is extracted. Strong reduction of the recycling...

Abstract In this paper, we propose a new type of weighted essentially non-oscillatory (WENO) limiter, which belongs to the class of Hermite WENO (HWENO) limiters, for the RungeKutta discontinuous Galerkin (RKDG) methods solving hyperbolic conservation laws. This new HWENO limiter is a modification of the simple WENO limiter proposed recently by Zhong and Shu [32]. Both limiters use information ...

BACKGROUND The objective of this study is to analyse the effectiveness of the surgical torque limiter during operative use. The study also investigates the potential differences in torque between hand and drill-based screw insertion into locking plates using a standardised torque limiter. METHODS Torque for both hand and power screw insertion was measured through a load cell, registering 6.66...

This document describes the details of our simulation. We simulate the necessary optical phenomena that affect the image quality. We also show the results with an angle limiter. Figure 1: Misalignment error caused by the curvature of the image surface. Since the distance from the GRIN lens to the image point B is longer than the radius of the image surface, angle S 2 (= S 1) is smaller than S 3...

This paper studies bifurcations in a three node power system when excitation limits are considered. This is done by approximating the limiter by a smooth function to facilitate bifurcation analysis. Spectacular qualitative changes in the system behavior induced by the limiter are illustrated by two case studies. Period doubling bifurcations and multiple attractors are shown to result due to the...

Micro pulse lidar is a promising tool for retrieving the convective boundary layer height (CBLH), but its application has been hindered by sharp extinction of the signal in high humidity conditions, e.g., clouds. To remedy this, we developed an effective and simple limiter to obtain more accurate estimates of the CBLH. The limiter is based on the algorithm for the convective condensation level ...

In this paper we generalize a new type of compact Hermite weighted essentially nonoscillatory (HWENO) limiter for the Runge-Kutta discontinuous Galerkin (RKDG) methods, which were recently developed in [34] for structured meshes, to two dimensional unstructured triangular meshes. The main idea of this limiter is to reconstruct the new polynomial using the entire polynomials of the DG solution f...
