On the solution of the nonsymmetric T-Riccati equation. ETNA - Electronic Transactions on Numerical Analysis
No full textThe nonsymmetric T-Riccati equation is a quadratic matrix equation where the linear part corresponds to the so-called T-Sylvester or T-Lyapunov operator that has previously been studied in the literature. It has applications in macroeconomics and policy dynamics. So far, it presents an unexplored problem in numerical analysis, and both theoretical results and computational methods are lacking in the literature. In this paper we provide some sufficient conditions for the existence and uniqueness of a nonnegative minimal solution, namely the solution with component-wise minimal entries. Moreover, the efficient computation of such a solution is analyzed. Both the small-scale and large-scale settings are addressed, and Newton-Kleinman-like methods are derived. The convergence of these procedures to the minimal solution is proven, and several numerical results illustrate the computational efficiency of the proposed methods

No full textThis article is an experiment: it attempts to look at medieval Latin translation practices through the lenses of a modern sociological theory of narrative. It argues that topoi found in translation prefaces are key elements of narratives that explain why the act of translation is necessary at all. The article identifies three such narratives, and elaborates in particular on one of them, which describes translation with the help of bellic metaphors

No full textMeasuring Ultrafine Particle Concentrations at Salzburg Airport: Using the Airport Closure due to Runway Reconstruction as a Natural Experiment. GI_Forum|GI_Forum 2020, Volume 2|
No full textDuring April and May 2019 Salzburg Airport was closed for five weeks for runway renovation. As a result, landings and take-offs (LTOs) were impossible during this period. This offered a rare opportunity to carry out a field study to investigate the concentration of ultrafine particles prior to, during and after completion of the renovation work. During the construction phase, the sharp particle concentration peaks resulting from LTOs during normal operation were no longer encountered at the measurement site, 140 m from the runway. Towards the end of the airport closure, construction activity was all but completed and LTO activity was strictly limited to test purposes, which resulted in average ultrafine-particle concentrations of approximately 3,000 to 4,000 cm-3 (06–23 h average value). The reconstruction work itself and the high numbers of construction vehicles caused an increase in ultrafine-particle concentrations of an additional 1,000 to 2,000 cm-3 (06–23 h average value). In comparison, in the three weeks before and the three weeks after the closure, when airport operations were running as normal, concentrations increased by 3,000 to 4,000 cm-3 (06–23 h average value)
