SUMMARY:ALOP-Colloquium with Dr. Christina Schenk\, Basque Center for Applied Mathematics
DESCRIPTION:On Monday\, December 7\,  2020 at 16:00 c.t. Dr. Christina Schenk will present her recent work titled “Population Balance Modeling\, Simulation and Optimization: From Wine Fermentation to Polymerization” at our colloquium.  \nAbstract: \nThe continuous increase of energy consumption and pollution by carbon dioxide emissions worldwide requires\nimprovements in terms of energy efficiency and advanced materials. Within the scope of this talk we look at\ndifferent aspects regarding mathematical modeling\, simulation and optimization for several industrial applications.\nThe proposed mathematical advances tackle the dynamical processes\, and modeling such processes is\ncrucial for many applications. We focus in particular on the process of wine fermentation driven by the yeast cell\ngrowth dynamics and the polymerization of composite (multi-phase) polymer particles which strongly depends\non the evolution of the particle morphology. For these applications we propose models based on population\nbalance equations and derive numerical solution strategies that are adjusted to the specific model properties.\nThese solution approaches reach from finite volume based schemes to the generalized method of characteristics.\nThe arising challenges associated with these types of problems are addressed and handled by newly developed\ntechniques\, such as Optimal Scaling with Constraints. The investigations are underlined with selected analytical\nstudies. The significance of the proposed methodologies is highlighted and verified by numerical results.\n(This is joint work with: S. Rusconi (BCAM)\, E. Akhmatskaya (BCAM\, Ikerbasque\, Berkeley Lab)\, V. Schulz\n(Trier University)\, D. Sokolovski (UPV/EHU\, Ikerbasque)\, A. Zarnescu (BCAM\, Ikerbasque)). \nThe event is a virtual event via ZOOM. The link will be distributed via email. \n

SUMMARY:ALOP-Colloquium with Prof. Dr. Falk Hante\, HU Berlin
DESCRIPTION:On Monday\, December 14\, 2020 at 16:00\, Prof. Dr. Falk Hante\, Humbold Universität zu Berlin will present his recent work at our colloquium. \n  \nTitle: Sequential action control for stabilization of PDE-dynamical systems \nWe present sequential action control as a framework suitable for control and stabilization of PDE-dynamical problems. As a variant of a moving horizon method\, but in contrast to classical model predictive control approaches\, the control synthesis does not require to compute solutions of dynamic optimization problems. Moreover\, the control principle can be easily extended to piecewise linear switched systems and other heterogenuous optimal control problems being motivated\, for example\, by gas network operation. We use Riccati theory for the qualitative analysis of the method and present results prototypically for the stabilization of an unstable reaction-diffusion process. \nReferences:\n[1] Y. Brodskyi\, F.M. Hante\, A. Seidel: Stabilization of Partial Differential Equations by Sequential Action Control. TRR154 Preprint 271\, 2019. \n  \nThis presentation will take place via ZOOM. A link will be e-mailed prior to the event.
