Highly-parallelized simulation of a pixelated LArTPC on a GPU

2023

The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The alg…

Improving Economic Management Decisions in Forestry with the SorSim Assortment Model

2020

The sustainable supply of timber is one of the most important forest ecosystem services and a decisive factor determining the long-term profitability of forest enterprises. If timber production is to be economically viable, there must always be a way to analyse forest stands and trees felled for exploitation with regard to the wood assortments they contain. Only then can the expected timber yields, achieved by various silvicultural strategies or actions and different sorting options, be quantified with sufficient accuracy. The SorSim assortment simulator was developed for forest practitioners and forest scientists in Switzerland to realistically simulate the sorting of individual trees and …

Numerical studies on neutrino oscillation physics in long baseline experiments

2018

This thesis examines the prospects of future long baseline neutrino oscillation experiments. Using computer simulation techniques, we calculate the experimental sensitivities for two experimental configurations in a set of important questions which are all relevant for modern day neutrino physics. First, we set focus on the determination of the θ23 octant, where the aim is to find whether the atmospheric neutrino mixing angle θ23 lies in the high octant, θ23 > 45◦, or in the low octant, θ23 < 45◦. On the other hand, we study how well the long baseline experiments could test the limits of the Standard Model by seeking deviations from the oscillation patterns that follow from the standard three…

Evolution and decay of an Alice ring in a spinor Bose-Einstein condensate

2023

We use first-principles-derived numerical simulations to investigate the long-time evolution of a half-quantum vortex ring, an Alice ring, arising from the decay dynamics of an isolated monopole in the polar phase of a dilute spin-1 Bose-Einstein condensate. In particular, we study the lifetime and decay characteristics of the Alice ring under different experimentally relevant conditions. We observe that, in a 87Rb condensate with a homogeneous external magnetic field, a well-centered Alice ring may survive for over 160 ms, and that during its lifetime it can contract back into a monopole, which again converts into an Alice ring. Interestingly, we notice an additional Alice ring, with an op…

Mediation in practice in an ESAP course : Versions of the Medical English student conference

2021

The Medical English course at the University of Oulu (Finland), which is compulsory for 200 first-year medical students, is designed to enhance professional English language communication focusing on work life relevance. The course design utilized the action-oriented approach promoted by CEFR CV (2018), to support the active use of language through various simulation activities. This paper describes specifically the final assignment of the Medical English course, which is integrated with the Clinical Psychology course. Having discussed topics in Finnish in groups, complementing the lectures in the Clinical Psychology course, students present in English what they have learnt in these discuss…
