Computation is a cornerstone of modern scientific research, and consequently many universities are actively working to incorporate computational methods into their science courses.

At the University of Oslo, this work has been going since the early 2000s and currently all bachelor programs in mathematics and natural science integrate computing from day one.

For example, in the physics bachelor program, students learn computation in through coordinated mathematics, physics and, computer science courses, and computation is then threaded through most subsequent physics courses.

In this talk, we address the Norwegian educational context, challenges and experiences from establishing such a program, examples of how the program is implemented, and how we work to integrate computing in programs across contexts and across educational levels.

We will also discuss what we are learning through our research activities on how students build computational literacy, and how computation can support student conceptual understanding and epistemic agency.   

We would like to invite members of the physics education research groups of Michigan State University, University of Colorado-Boulder, and Oregon State University, as well as our Scandinavian PER colleagues, to a summer institute held in Oslo, Norway, and hosted by the Center for Computing in Science Education at the University of Oslo.

Tittel: Numerical Investigation ofTurbulent Flow in HelicallyCoiled Pipes

Hylleraas seminar, hosted in Oslo

Brain source analysis is an important tool in brain research. It is used for example during operation planning for epilepsy patients. Given EEG (electroencephalography) and MEG (magnetoencephalography) measurements the goal is to reconstruct the brain activity, i.e. the electric potential in the brain. This poses an inverse problem. It was observed in experiments, that the accuracy of the inverse problem strongly depends on the quality of the forward simulation, in particular the head model. We discuss how modern numerical methods like discontinuous Galerkin (dG) methods and cut-cell techniques can increase the robustness of the forward problem and simplify the overall workflow. Hardware-oriented design of numerical methods allows for improved speed of the inverse simulation by making use of modern hardware resources. In order to compute the forward problem efficiently, we propose an algebraic multigrid solver for cut-cell dG methods. We introduce the challenges of EEG/MEG inverse modeling and discuss how different parts of the problem can be improved using modern numerical methods.

Risk in stochastic control and reinforcement learning

Abstract: Many constructions have been proposed to attain adaptivity within the IGA framework (HB-, T-, LR-splines among others).
The idea of all approaches is to break the tensor product structure of the space in order to allow a spatially varying resolution.
Here we present an approach for adaptivity in IGA aimed at solving PDEs with preconditioned Krylov methods. 
All the main ingredients of this work are already known, but their combination looks promising for the 
development of isogeometric solvers with a good balance of flexibility and computational efficiency.
