This post is about our project with Airbus dedicated to variation simulation for the assembly process. Our research team in the SPbPU has been developing this area since 2006. When we design a mathematical model for the assembly process it is important to remember that in reality, the assembled parts […]

MathTech workshop in Poland
On 4.12.2020, the first MathTech Workshop on Mathematical Technologies for Industry was held in Poland. It was organized by the PL-MATH-IN network as a satellite event of the annual EU-MATH-IN Council Meeting. Originally, the workshop was planned to be held at the Institute of Mathematics of the Polish Academy of […]
Read moreLocal defect detection in bearings in the presence of impulsive noise and spectral overlapping of informative and non-informative impulses
Predictive maintenance has been pointed out as one of the key elements of industry 4.0 philosophy. Measurement of diagnostic signals and advanced analytics allow to detect damage, identify its type, localize it in the machine, and even make some prognosis of remaining life. The efficiency of diagnostic procedures depends on […]
Read moreRelaxation-oscillations in a conceptual climate model
Conceptual climate models are relatively simple mathematical constructs that can capture essential features of the nonlinear nature of the climate. They usually focus only on several ingredients of the physical description and model their interplay. As can be easily noticed, due to their simplicity, they cannot be used as computation […]

Technische Universität Darmstadt decided around 2001 to brand its interdisciplinary activities in modeling, analysis, simulation and optimization of scientific and engineering applications under the label of Computational Engineering (CE).
Read moreElectro-Thermal Modeling of High-Temperature Superconducting Coils and Magnets in Collaboration With CERN
Superconducting magnets are used in high-energy particle accelerators such as the Large Hadron Collider at CERN to exert electromagnetic forces on the particle beam. These forces keep the particles on a circular path by, e.g., bending the path of the beam and keeping it focused. High-temperature superconducting (HTS) materials are […]
Read moreAI-TWILIGHT: AI powered Digital Twin for lighting infrastructure in the context of front-end Industry 4.0
Over the last decades, LEDs have taken over the lighting industry. Their design is a multiphysical problem, involving mechanical, optical, electrical, and thermal components and considerations. All of these domains influence the operational behavior of LEDs, with the temperature having the largest impact on the lifetime of a given product. […]
Read moreFinite Element Parasitic Extraction and Sensitivity Analysis in Industry
Parasitic extraction is a key technique in electromagnetic compatibility analysis. It enables to extract the parasitic resistances, inductances, and capacitances from a CAD model, and thereby to asses the performance of the design in a joint circuit simulation in combination with its functional circuit elements. A sensitivity analysis of the […]
Read moreModelling Ground Temperatures for the Climate Model LPJmL4
by Julia Niebsch Climate models are used to make predictions about the future development of the climate. These models use a variety of factors like aerial CO2 levels, sea temperatures and forestation to determine possible outcomes of the ongoing climate crisis. These physical and chemical processes can be described through […]
Read moreMathematics for Ophtalmology
by Julia Shatokhina Optical coherence tomography (OCT) is a powerful interferometric technique providing non-invasive 3D imaging of sub-surface structures with resolutions on the micrometer scale. Significant developments of the OCT techniques in the recent decades were observed especially in biomedical applications. Thus, in ophthalmology the OCT imaging technique has revolutionized […]
Read moreMathematics in industry reports (miir)
Supported by ECMI, Cambridge University Press now hosts and organises reports from Study Groups with Industry. This is an on-line repository of reports from study groups around the world. MIIR provides visibility for early stage research in industrially relevant mathematics. A report in MIIR, while not a peer-reviewed publication, is a […]

by Stefan Raffetseder Using measurements of multiple guide stars in different directions inan Adaptive Optics system leads to the problem of atmospheric tomogra-phy. Usually, this problem is solved by an inverse matrix operation, whichrequires O (n2) operations. Since the new generation of ground-based tele-scopes have a diameter of 30m and […]
Read moreModel order reduction for the simulation of parametric interest rate models in financial risk analysis
by Andreas Binder, Onkar Jadhav, and Volker Mehrmann, in: Journal of Mathematics in Industry, Volume 11 (8), 2021 Abstract This paper presents a model order reduction approach for large scale high dimensional parametric models arising in the analysis of financial risk. To understand the risks associated with a financial product, […]

by Michael Reichelt, Markus Windisch, Günter Offner, and Sarah Santner inETNA, Volume 54, pp. 355-369, 2021 Abstract The well-known Reynolds equation is typically used to compute the pressure distribution for elasto-hydrodynamic contacts of parts, as, for instance, in radial slider bearings. In order to resolve local pressure phenomena like edge […]
