Short-term interactions between Staphylococcus aureus and Pseudomonas aeruginosa: BEP Report

Staphylococcus aureus and Pseudomonas aeruginosa are two species of bacteria that are involved in numerous conditions, including lung infections and chronic wound infections. The aim of this project was to study the short-term interactions that occur when P. aeruginosa first encounters an established S. aureus colony, which it then seeks to...

Developing a Solid-State Battery Phase-Field Model

The ongoing worldwide energy transition has prompted significant scientific interest in energy storage. Rechargeable lithium-ion batteries have become a standard for energy storage in mobile devices and electric vehicles for their mass-energy density. While industry standard lithium-ion cells are currently based on liquid electrolytes, solid...

Analyse van e-gitaar signalen in tijd- en frequentiedomein, in termen van snaar- en rand-dynamica: Analysis of e-guitar signals in time and frequency domain, in terms of string and boundary dynamics

In this thesis we examine various aspects of the output signal produced by the electrical pickup of an electric guitar. We do this by formulating a model of this output signal based on the one dimensional damped wave equation for the motion of one guitar string and (initially) a simple linear model for the output signal based on this motion....

Understanding and predicting ice growth on Dutch lakes and canals

A brief study to understand the physical driving forces concerning ice growth. These forces are mathematically described in a basic prediction model. Further complexity to the model is added through adopting various assumptions about the physical factors involved.

Geomechanical modeling of a fault-propagation fold

The goals of this thesis were to understand the impact of uncertainties and modeling methods on the resulting stress and strain patterns and to see how 3D stress patterns can be linked to what was seen in the field. In 3 types of models simulations were done to carry out this goal. These are the 2D perturbation model, the 2D static model, and...

Sedimentation reduction and check dam design in the Cilalawi River

An overdose of sediment from the Cilalawi River is going into the reservoir Waduk Jatiluhur. This is resulting in the problem of reservoir capacity reduction. With water still coming from different rivers, the future will be inundation. In this matter the recommendation for this problem is check dam(s) and changing land use, stated by the local...

Modelling and simulation of bone implant healing

In this report a model for the ingrowth of a prosthesis in a bone will be formulated and simulated. First an overview is given of all the biological processes that are part of this healing process and what external factors can influence this process. Then a first mathematical model is presented in which the mechanical stimuli (one of the...
