Björn Luig (Uni Münster): Improving the Energy Efficiency of Transport Units in a Linear Transport System through Setpoint Generation with Optimal Control

Wednesday, 17.04.2024 14:15 im Raum M5

Mathematik und Informatik

The company Beckhoff Automation produces a linear transport system "in which magnetically driven movers move along a travel path of fully integrated motor modules. An Industrial PC with [...] automation software enables the independent control of the movers with individual motion profiles." In my master's thesis, I develop a model for the power consumption of such a mover depending on the motion profile. It considers mass and acceleration along straight and curved tracks, friction, and magnetic effects across different motor modules and movers. The ultimate goal is to develop a fast optimization algorithm to calculate more energy-efficient motion profiles within the bounds of technically feasible paths for dynamically changing applications.

Chinmoy Bhattacharjee, Univ. Hamburg: Spectra of Poisson Functionals and Applications in Continuum Percolation (Oberseminar Mathematische Stochastik)

Wednesday, 17.04.2024 16:30 im Raum SRZ 203

Mathematik und Informatik

In this talk, I will consider the noise sensitivity of dynamical critical planer continuum percolation models, such as the Boolean model and Voronoi percolation model. While similar results for the Voronoi percolation have previously been shown in Vanneuville (2021) under the so-called frozen dynamics, we instead consider the Ornstein-Uhlenbeck (OU) dynamics. A critical planer dynamical percolation model is said to be noise sensitive if the ±1-indicator of a left-right occupied crossing of large squares of side length L in the model is sensitive to small noises in the underlying system. We introduce the noise according to the OU dynamics and show a sharp transition result : when the amount of noise tends to zero as L \to\infty fast enough, then the model is not sensitive to the noise, while if it doesn?t tend to zero fast enough, the model becomes noise sensitive. The main tool is a notion of spectral point process based on the chaos expansion of the crossing functionals, which parallels the corresponding notion of spectral samples in the discrete setting. The talk is based of a joint work with Giovanni Peccati and Yogesh- waran Dhandapani.

Dr. Nicola Vassena (IZBI Universität Leipzig): Which sub-structures cause instability in biological networks?

Wednesday, 24.04.2024 15:00 im Raum M5

Mathematik und Informatik

In this talk, I will consider biochemical networks and address the existence of unstable equilibria based only on the network structure. In particular, I will identify minimal sources of instability, so-called unstable cores, and discuss several of their features. For example: an unstable core can be classified in autocatalytic vs nonautocatalytic, and the presence of at least one autocatalytic core characterizes autocatalysis in network. Further, unstable cores serve as predictive tools for understanding the dynamic range of a network, sufficiently determining whether a network admits multiple equilibria or periodic oscillations. The presented approach relies on bifurcation theory and multiscale methods.

Dominik Schmid, Univ. Bonn: Approximating the stationary distribution of the open ASEP (Oberseminar Mathematische Stochastik)

Wednesday, 08.05.2024 14:00 im Raum SRZ 216

Mathematik und Informatik

The exclusion process is one of the best-studied examples of an interacting particle system. In this talk, we consider the stationary distribution of asymmetric simple exclusion processes with open boundaries. We project the stationary distribution onto a subinterval, whose size is allowed to grow with the length of the underlying segment. Depending on the boundary parameters for the exclusion process, we provide sufficient conditions such that the projected stationary distribution is close in total variation distance to a product measure. This talk is based on joint work with Evita Nestoridi.
