The paper presents how Grafchart can be used to implement batch recipe structures. Grafchart, a toolbox based on Grafcet/SFC, object-oriented programming constructs and ideas from high-level Petri nets, is presented in the paper. Grafchart exists in two versions, one basic version and one high-level version. By using the different features of Grafchart in various ways, recipes can be given differe
We report the realisation of spectroscopic broadband transmission experiments on quantum cascade lasers (QCLs) under continuous wave operating conditions for drive currents up to laser threshold. This technique allows, for the first time, spectroscopic study of light transmission through the waveguide of QCLs in a very broad spectral range (λ~1.5-12 μm), limited only by the detector response and b
The Augustan poet Ovid (43 BC – AD 17/18) is mentioned by Seneca the elder for his oratorical skills as a school boy. If we are to believe Seneca, Ovid excelled to such a degree that he even surpassed his teachers. He took special interest in exercises concerning ethos, and is said to have transferred what he learned into his own verse. The influence from rhetorical training is indeed visible in O
