We combine a pressure correction scheme with interior penalty discontinuous Galerkin (dG) discretisation to solve the time-dependent Navier–Stokes equations. We prove unconditional energy stability and a priori error estimates for the velocity. With duality arguments, optimal L2 error rates are obtained. Convergence of the discrete pressure is also established.  Further, we propose a splitting scheme,  integrating the pressure correction approach, for the Cahn–Hilliard–Navier–Stokes system  The numerical analysis of dG combined with this scheme is discussed. Namely, we show well--posedness, stability, and error estimates. Numerical results with manufactured solutions display our theoretical findings, and a spinodal decomposition example portrays the robustness of our approach.

Welcome to our weekly lunch seminar held in the dScience lounge area. This Thursday we are happy to welcome Olivier Lartillot and Lars Monstad from RITMO Centre for Interdisciplinary Studies in Rhythm, Time and Motion.

Welcome to this conference for CompSci PhD candidates and supervisors. The conference is also open for people interested in these topics, and for the CompSci partners. 

Traditional quantile estimators are not well-suited for data streams because the memory and computational time increase with the volume of data received from the stream. Incremental quantile estimators refer to a class of methods designed to maintain quantile estimates for data streams. These methods operate by making small updates to the estimate every time a new observation is received from the stream. In this presentation, I will introduce some of the incremental quantile estimators we have developed.

Elise Lockwood: 

Computational thinking and activity are becoming an increasingly important aspect of what it means to conduct scientific and mathematical work. In light of this, there is a need for mathematics education studies that examine the ways in which students engage with computational tools as they reason about scientific and mathematical concepts.

In this talk, I provide an example of how such computational activity can support the desirable mathematical practice of generalizing. I provide data from an interview with a student who engaged in generalizing activity while using Python to solve combinatorial problems.

I connect his work to the literature on generalization and suggest that there are promising avenues to pursue in leveraging computing for such mathematical practices. I conclude by framing this work within ongoing efforts to better understand the nature of computational thinking and activity for undergraduate students.

Hylleraas seminar, hosted in Oslo

Your brain has its own waterscape: whether you are reading, thinking or sleeping, fluid flows through or around the brain tissue, clearing waste in the process. These biophysical processes are crucial for the well-being and function of the brain. In spite of their importance we understand them but little, and mathematical and computational modelling could play a crucial role in gaining new insight. In this talk, I will give an overview of mathematical, mechanical and numerical approaches to understand mechanisms underlying pulsatility, fluid flow and solute transport in the human brain. Topics include fluid-structure interactions, generalized poroelasticity, mixed finite element discretizations and preconditioning, uncertainty quantification, and optimal control.
