Shock Tube Testing and Modelling of Annealed Float Glass

Optimization of automated float glass lines

In automated float glass manufacturing, a continuous ribbon of glass is cut according to customer orders and then offloaded using robots. We consider the problem of laying out and sequencing the orders on the ribbon so as to minimize waste. The problem combines characteristics of cutting, packing, and sequencing problems. Given the size and the complexity of the problem, we propose a two-phase ...

Cathodoluminescence and depth profiles of tin in float glass

Cathodoluminescence (CL) spectra have been recorded from float glass samples and the data used to determine the depth profile of tin introduced from the float process. The luminescence data were interpreted in terms of intrinsic emission bands at 380 and 410 nm and well resolved extrinsic emission bands resulting from the tin impurities at 575 and 630 nm. Signals were recorded at temperatures f...

A cutting and scheduling problem in float glass manufacturing

This paper considers a cutting and scheduling problem of minimizing scrap motivated by float glass manufacturing and introduces the FGSP (float glass scheduling problem). We relate it to classical problems in the scheduling literature such as no-wait hybrid flow shops and cyclic scheduling. We show that the problem is NP-hard, and identify when each of the problem’s components are polynomially ...

We study the asymptotic behavior of asymmetrical spin glass dynamics in a Sherrington-Kirkpatrick model as proposed by Sompolinsky-Zippelius. We prove, without any condition on time and temperature, an annealed propagation of chaos result. Extending this result to replicated systems, we conclude that the law of a single spin converges to a non markovian probability measure, in law with respect ...
