LPMLE3: A novel 1-D approach to study water flow in streambeds using heat as a tracer
Uwe Schneidewind,van M Matthijs Berkel,Christian Anibas,Gerd Vandersteen,Christian Schmidt,Ingeborg Joris,Piet Seuntjens,Okke Batelaan,Heiko J. Zwart +8 more
TL;DR: In this article, a 1-D approach to quantify vertical water flow components at streambeds using temperature data collected in different depths is introduced, where the streambed can be divided into finite subdomains bound at the top and bottom by a temperature-time series.
Journal ArticleDOI
Real-time wavelet detection of crashes in limit cycles of non-stationary fusion plasmas
van M Matthijs Berkel,van M Matthijs Berkel,Gert Witvoet,Gert Witvoet,de Marco Baar,de Marco Baar,Pwjm Pieter Nuij,ter Hg Hennie Morsche,M Maarten Steinbuch +8 more
TL;DR: This paper presents an algorithm for optimized (low latency, robust and high fidelity) real-time sensing of the crashes, based on time-scale wavelet theory and edge-detection, which is robust and accurate.
Journal ArticleDOI
Explicit approximations to estimate the perturbative diffusivity in the presence of convectivity and damping. II. Semi-infinite cylindrical approximations
van M Matthijs Berkel,G. M. D. Hogeweij,Naoki Tamura,Hans Zwart,Shigeru Inagaki,de Marco Baar,Katsumi Ida +6 more
TL;DR: In this article, a number of new explicit approximations are introduced to estimate the perturbative diffusivity (χ), convectivity (V), and damping (τ) in a cylindrical geometry.
Estimation of heat transport coefficients in fusion plasmas
TL;DR: A submitted manuscript is the author's version of the article upon submission and before peer-review as discussed by the authors, and the final published version features the final layout of the paper including the volume, issue and page numbers.
