Students' Talks
On Friday 11 June 2021 at 9:30 AM we are hosting the final seminar of this term, during which we will hear short presentations by:
Antoni Wrzos
Selected ideas in modelling of blood vessels
The presentation is covering some general ideas connected with modelling of blood vessels growth. A bit more will be said about cellular Potts model (CMP) and finite element method (FEM), based on an article written by Merks et al., 2014. Also the talk will touch results from their model and some of its limitations.
Kamil Gmiterek
The rigged Hilbert space and resonances in QM
In QM Dirac's bra-ket formalism is fully implemented by the rigged Hilbert spaces rather than just by the Hilbert space. To describe the full spectrum of a quantum system (bound, scattering and resonant parts) one have to enlarge the Hilbert space to a rigged Hilbert space (Gelfand triplet). Using mathematical tools from the theory of distributions one can provide an appropriate meaning of objects like eg. the delta function.
Dominik Suwała
A tour on CFD algorithms: SIMPLE
I this talk I will present one of the widely used computational fluid dynamics (CDF) algorithm: SIMPLE (Semi-Implicit Method for Pressure Linked Equations). I will start from the Navier-Stokes equations and go through the SIMPLE solution process while covering topics like different discretization schemes and pressure correction methods. Finally I will give some comments on the SIMPLE-based algorithms SIMPLER and SIMPLEC.
Stanisław Żukowski
Hydrodynamical instabilities - why does water spill out of a bucket?
The question from the title may sound trivial, however, I will present some examples of home experiments, where one observes water in the jar positioned upside down, which remains stable and does not spill. In my short talk I will try to answer what differs the bucket and the jar, which will lead us to a description of so-called Rayleigh-Taylor instability.
Marcin Pruszczyk
One-dimensional Bose gas with attractive boundary conditions
In one-dimensional ideal Bose gas with the so-called attractive boundary conditions Bose-Einstein condensation is observed. It is a phase transition of second order in regards to the Ehrenfest classification. The phase containing the condensate is not homogeneous - the condensate is localised in the vicinity of point-like walls confining the gas.
The seminar will be held on Zoom
