The dynamics of a driven harmonic oscillator coupled to pairwise interacting Ising spins in random fields

no code implementations22 Jun 2020 Paul Zech, Andreas Otto, Günter Radons

We show, how the dynamical properties of the piecewise-smooth system for a large number of spins differs from the system in its thermodynamic limit.

Chatter Detection in Turning Using Machine Learning and Similarity Measures of Time Series via Dynamic Time Warping

no code implementations5 Aug 2019 Melih C. Yesilli, Firas A. Khasawneh, Andreas Otto

In this paper, we present an alternative approach for chatter detection based on K-Nearest Neighbor (kNN) algorithm for classification and the Dynamic Time Warping (DTW) as a time series similarity measure.

Topological Feature Vectors for Chatter Detection in Turning Processes

no code implementations21 May 2019 Melih C. Yesilli, Firas A. Khasawneh, Andreas Otto

We present the results for several choices of the topological feature vectors, and we compare our results to the WPT and EEMD methods using experimental turning data.
