Control of Delay Propagation in Railway Networks Using Max-Plus Algebra

In this thesis max-plus algebra is introduced and applied to the problem of controlling train delays. Two control strategies for the propagation of delays are discussed. The first is by letting certain trains run faster when a delay is detected, the second is by breaking connections between trains that have to wait for each other in order to...

On discrete and continuous state adaptive network models: with an application to self-organisation in swarming systems

We consider adaptive network models with discrete and continuous state sets obeying dynamical rules that enable application to swarming systems. The 2-state adaptive network contains a supercritical pitchfork bifurcation in the transition between ordered and disordered stationary solutions. We derive an adaptive network model that works on a...

Fatigue Modelling With A Two-Dimensional Spring Network

A random periodic two-dimensional spring network us built using a Poisson disk distribution and computing the Delaunay triangulation of the centers of the disks. The edges of the network represent springs that obey Hooke’s law with an adjustment on the spring constant. The adjustment allows spring to soften and to break. The two-dimensional...

Determination of the Magnetic Background Field on Naval Ships

For my bachelor’s graduation project, I did an internship at TNO, working on a project for the Ministry of Defence. This thesis describes and discusses the project that looked for a prediction model for the magnetic background field on a naval ship. The prediction model that was developed during this project separates the magnetic background...

Optimaliseren van de service van een taxisysteem met zelfrijdende voertuigen

Dit project behandelt de programmering en toepassing van een taxiservice, waarbij de passagiers zich vanaf of naar het treinstation willen verplaatsen. Met behulp van geheeltallig lineair programmeren wordt bepaald welke ritten door de taxi's moeten worden gereden, om de winst te maximaliseren. Dit model is gebaseerd op het model wat beschreven...
