Industrie 4.0 und maschinelles Lernen (ML) versprechen hohes Potenzial der Effizienzsteigerung für die Produktion. Die Etablierung in der Praxis bedarf kleiner, umsetzungsfähiger Beispiele um den Nutzen aufzuzeigen. Dieser Beitrag beschreibt das Vorgehen für die Vernetzung einer Maschine zur nicht-isothermen Glasumformung und anschließender Verwertung der Daten mittels ML. Das übergeordnete Ziel dabei ist, die Optimierung der Prozessparameter durch eine Prognose der Qualität der Endprodukte zu erreichen.
Industry 4.0 has become a widely understood term. Establishment in practice requires small, implementable examples to show concrete potenzials. This article describes the procedure for networking a machine for non-isothermal glass forming and subsequent utilization of the data by means of machine learning (ML). The overall goal is to optimize the process parameters by predicting the quality of the end products.
8 págs.; 11 figs. ; PACS number(s): 21.60.Fw, 21.30.Fe, 23.40.Hc ; We examine isovector and isoscalar neutron-proton correlations in an exactly solvable model based on the algebra SO(8). We look particularly closely at Gamow-Teller strength and double β decay, both to isolate the effects of the two kinds of pairing and to test two approximation schemes: the renormalized neutron-proton quasiparticle random phase approximation (QRPA) and generalized BCS theory. When isoscalar pairing correlations become strong enough a phase transition occurs and the dependence of the Gamow-Teller β strength on isospin changes in a dramatic and unfamiliar way, actually increasing as neutrons are added to an N=Z core. Renormalization eliminates the well-known instabilities that plague the QRPA as the phase transition is approached, but only by unnaturally suppressing the isoscalar correlations. Generalized BCS theory, on the other hand, reproduces the Gamow-Teller strength more accurately in the isoscalar phase than in the usual isovector phase, even though its predictions for energies are equally good everywhere. It also mixes T=0 and T=1 pairing, but only on the isoscalar side of the phase transition. ©1997 American Physical Society ; This work was supported in part by the National Science Foundation under Grant Nos.
