Swaab, Vera (author)In this paper, it is analysed how an infinite cable behaves when a wave from the right hits a TMD system attached to it. The TMD system consists of a mass M1, a spring with stiffness K, a damper with coefficient C and a second mass M2. The cable has a tension T. Then it is investigated what happens when a wave goes through the cable and hits...bachelor thesis 2020

Rustici, Pietro (author)This study investigates whether an automatic anonymization algorithm that takes as input a 3D model of a human face can produce an output model exempt from General Data Protection Regulation (GDPR) biometric data definition. The algorithm first uses Random Sample Consensus (RANSAC) for registering the source point cloud globally to an oriented...bachelor thesis 2020

Oderwald Blázquez, Adrian (author)In riverine environments under anaerobic conditions, methane and carbon dioxide are produced as a result of biological activity, causing degradation of organic matter. Under aerobic conditions, the bacteria present degrade the organic matter, whereby the concentration of dissolved oxygen may be lowered. Thus, issues experienced in the...bachelor thesis 2020

Fung, Kevin (author)A polymersome is a type of nanocarrier made of amphiphilic block copolymers, consisting of a hydrophobic bilayer, a hydrophilic brush-like outer shell and a hollow, aqueous core, which is formed through self-assembly. Polymersomes could be useful in the treatment of cancer as carrier to deliver and release drugs or radionuclides to tumours...bachelor thesis 2020

Abbasi, Anas (author)Alkali-activated concrete (AAC) has emerged as an environmentally friendly alternative to conventional concrete, as It is a cement-free concrete made by activating precursors (mainly low-cost, low-CO2 industrial by-products) with alkalis. AAC has demonstrated some remarkable mechanical properties and long-term performance (e.g., high strength,...bachelor thesis 2020

van Lieshout, Toon (author)A look at Wythoffs Nim, Wythoff rows and Akiyama's nim. We try to find a row and a game that match Wythoff's row and game. A row is found in the Lieshoutrow, but the game we chose: Akiyama's nim, wasn't close to the beauty of Wythoff's nim. We exolain why.bachelor thesis 2020

Jansen, Flip (author)Structural and functional characterization of membrane proteins (MPs) requires extraction from the native lipid bilayer, which generally necessitates the formation of water-soluble MPs structures or complexes suitable for biochemical assays. These structures are often detergent micelles that form protein-detergent complexes (PDCs), due to...bachelor thesis 2020

van Winden, Joris (author)In this thesis, networks of coupled quantum harmonic oscillators are studied. The dynamics of these networks are determined by single-frequency vibrations of the entire network called normal modes. We study the behavior of the nor- mal modes when the network is coupled to a thermodynamical heat bath by looking at the Lindblad Master Equation of...bachelor thesis 2020

Lu, Jenny (author)In this bachelor thesis we propose a spatial Markov Chain Cellular Automata<br/>model for the spread of the COVID-19 virus as well as two methods for parameter<br/>estimation. Network topologies are used to model the progression of the epidemic<br/>by considering each individual on a grid and using stochastic principles to determine the...bachelor thesis 2020

van der Wal, Gwyn (author)In this report, we will look at the connection between the Fibonacci and Euler numbers. By using a combinatorial argument including the Fibonacci and Euler numbers, we will prove our main theorem: F<sub>n</sub>·E<sub>n</sub> ≥ n! From the main theorem and the asymptotics of these numbers, we will conclude that π ≤ 2ϕ. We...bachelor thesis 2020

van Zwienen, Heike (author)context: The long-term evolution of a self-gravitating astrophysical disk can be modeled using secular perturbation theory. Recently, Batygin published a paper where he claims that such a disk with a special density can be described by a Schrödinger equation by using this method. aims: In this thesis, we will study the secular perturbation...bachelor thesis 2020

Imhof, Joost (author)There exist a lot of methods to find the electromagnetic field behind a lens, so called the forward lens problem. In contrast very few methods can do the inverse, namely finding a lens that would produce a given image or light distribution for a known source. Here a solution to the forward problem, the Fraunhofer approximation, is used to find...bachelor thesis 2020

Obbens, Ewald (author)This study is part of a larger effort to evaluate the use of microfluidics to represent foam generation and flow in geological porous media (Rossen, 2008). Specifically whether it is possible to have flow in a microfluidic device without fluctuating occupancy of pores and pore throats. Although there is no foam created during the study, three of...bachelor thesis 2020

Vermeulen, Joop (author)Stationary sets are important tools in proofs of properties in sets of uncountable cardinality. In this thesis we look at mapping properties between stationary sets. First, the theory necessary for the construction and evaluation of stationary sets is made. That is the theory of ordinal, cardinal and regular cardinal numbers is build up from the...bachelor thesis 2020

Adriaens, Michael (author)Er wordt geschat dat 80% van al het zuurstof op aarde geproduceerd wordt door fytoplankton. Dit is een soort eencellige plant die voorkomen in wateren over de hele wereld. Deze kleine planten worden voornamelijk gegeten door zoöplankton, kleine organismen bestaand uit meestal enkele cellen. Afsterving of overbevolking van fytoplankton heeft ook...bachelor thesis 2020

Titulaer, Björn (author)In this report we will take a look at various proofs of Ramsey's theorem, some of the bounds that result from those proofs and applications of Ramsey's theorem. We will consider the proof of Ramsey himself, the proof of Skolem, the proof given by Erd\H{o}s and Szekeres and the proof of again Erd\H{o}s and Rado. The best upper bound for higher...bachelor thesis 2020

Rooijakkers, Fleur (author)In the recent years, there has been a growing interest in molten salt reactors as a source of energy. To ensure molten salt reactor safety, it is vital to know the thermodynamic properties of the systems involved.
