Continuous and Discrete Algorithms for Modelling the Kessler Syndrome

This thesis contains the development of continuous Kepler orbit- and a discrete numerical integration-based collision detection algorithms in a system of LEO satellites, which in combination with collision algorithm form a simplified space debris evolution model. This model is then used to study the Kessler syndrome. The continuous and discrete...

Powerful world of (meta-)genomics held back by lack of Standard Operating Procedures: A computer science-oriented analysis on automated metagenomic approaches and pipelines, their common practices, and technical shortcomings

Context: The study and analysis of (meta-)genomics have been providing scientists with valuable insights into the functioning and composition of microbial communities. Latest advancements in next-gen and high throughput sequencing technologies have resulted in significant growth in the data produced and made available for further research. These...

Symmetries of the Standard Model

This thesis is divided into five parts (covering chapter 1–5), that together try to give the reader a basic understanding of the symmetries of and the mathematical structure behind the standard model. The first two chapters cover some Lie and representation theory of the Lie groups U(1), SU(2) and SU(3), which play a central role in the standard...

Estimatic

Amsterdam Airport Schiphol has 5 runways, each of which can be used for take-off or landing of aeroplanes. The weather heavily influences which runway configuration air traffic control might pick. Airport Forecasting Service (AFOS) predicts which configuration of runways works most efficiently given a set of expected weather conditions and the...

Het wortelsysteem van E8: Een model voor elementaire deeltjes?

In dit onderzoek wordt gekeken of het model voor elementaire deeltjes voorgesteld door de Amerikaanse fysicus Antony G. Lisi bevestigd of weerlegd kan worden. In dit model worden elementaire deeltjes gekoppeld aan wortels uit het wortelsysteem van E8 en worden ladingen gekoppeld aan gewichten van dit wortelsysteem. Interacties tussen deeltjes...
