Wildschut, Guillermo (author)In 2011 Avsec showed strong solidity of the qGaussian algebras, building upon previous results of Houdayer and Shlyakhtenko, and Ozawa and Popa. In this work we study this result as well as the necessary literature and qmathematics needed to replicate the proof. The literature is combined within this thesis, whilst additionally filling in gaps...master thesis 2020

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

Schaaphok, Marianne (author)Burn injuries occur daily and can have severe physical and mental effects both in short and long term, such as disabilities due to severe skin contraction. Even though the mortality rate has decreased over the years, the need for a higher quality of life after severe burns remains. Decreasing the probability of a severe contraction is essential...master thesis 2020

Barion, Antonio (author)Skin grafting is a common technique employed to treat patients after burn injuries. In contrast to the frequency and gravity of contractures following from skin grafts, the phenomenon itself is still poorly understood and subject of studies. The development of an accurate model of skin contractures will allow medical researchers to better...master thesis 2020

Ippolito, Giulia (author)This work is part of the lowfieldMRI project, which aims to bring portable, affordable, lowfieldMRI scanners to lowincome countries. Replacing the superconducting magnets of conventional scanners with standard ones can significantly reduce the costs, but it also has a negative impact on the SignaltoNoise Ratio (SNR). In order to circumvent...master thesis 2020

Aupérin, Alizée (author)Demand deposits modeling is of top importance for banking institutions and usually represents a large part of a bank portfolio. Even though these products seem rather simple at first glance, demand deposits are without a fixed maturity, generating uncertainties in the model. A significant amount of academic literature on this subject is...master thesis 2020

Teitsma, J.T. (author)The maritime inventory routing problem (MIRP) is a tactical and operational planning problem, that takes an integrated view on ship scheduling and inventory management for bulk products. Given production and consumption levels during a predetermined planning horizon, the problem aims at finding delivery schedules with minimal travel costs, such...master thesis 2020

Négyesi, Bálint (author)Backward stochastic differential equations (BSDE) are known to be a powerful tool in mathematical modeling due to their inherent connection with secondorder parabolic partial differential equations (PDE) established by the nonlinear FeynmanKac relations. The fundamental power of BSDEs lies in the fact that with them one does not merely obtain...master thesis 2020

Lu, Jenny (author)In this bachelor thesis we propose a spatial Markov Chain Cellular Automata<br/>model for the spread of the COVID19 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

Hermse, Femke (author)In this thesis we build a goal based planning framework that takes into account goal priorities. Goal based planning is a type of personal wealth planning, with a focus on the feasibility of an investor's goals. Currently, to take goal priorities into account a dynamic asset allocation is created. We focus on incorporating goal priorities by...master thesis 2020

Versendaal, Bryan (author)In this thesis we look at three different algorithms within the field of phylogenetics and create a proof of concept for using machine learning to improve the algorithms. The problems are the maximum agreement forest problem, the hybridization number problem and finally the tail move problem. A study of the problems show that they can all...master thesis 2020

Abouricha, Aya (author)In this report, a study of the behavior of a onepopulation and twopopulation dynamic CurieWeiss model is presented. This model describes the evolution of one and two populations of spins or opinions. In particular, we study the empirical average or magnetization and show that as the population sizes go to infinity, the evolution of these...bachelor thesis 2020

Kerckhoffs, Lennart (author)Flash calculations are used for the dynamic simulation of vaporliquid phase equilibria (VLE) in many chemical processes. When used to predict the composition of mixtures in VLE, the repeated applicatino of these flash calculations, particularly in dynamic cases can cause small inaccuracies to cascade. One way to prevent this, is to have strong...master thesis 2020

Gravendeel, R.J. (author)When creating electronic devices, it is essential to model what happens when an electromagnetic field hits the device and it scatters. Conventionally, this can be modelled using the MarchingoninTime algorithm. This can become computationally expensive for complex systems. To speed up the algorithm, the PlaneWave TimeDomain algorithm is...master 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

Pan, L.Y. (author)Porous asphalt resides on most top layers of Dutch roads. Scheduling maintenance for these roads is generally dependent on several factors, but ravelling, the loss of aggregates in the top layers, is the main reason for maintenance on Dutch roads. With the recent framework of the DOSLCMS scheme generating values for aggregate loss in...master thesis 2020

Rood, N.M. (author)In this study, two interest rate models are analysed in context of counterparty credit risk. The goal of the study is to find a model that performs well on historical simulation for the PFE and EPE. The two models analysed are the Dynamic NelsonSiegel model and the Displaced Diffusion model.<br/>In the Dynamic NelsonSiegel model, a Nelson...master thesis 2020

Missula, Sharanya (author)Vibrations or oscillations can be caused in overhead cable lines or bridge cables due to strong rain and winds, making the structure unstable.These vibrations can be mathematically described as a string like initial boundary value problem with nonclassical boundary conditions. In this thesis, we consider a nonlinear attachment at the boundary...master thesis 2020

Bacci di Capaci, G. (author)The bond market is affected by the shortage of liquidity problem, which means that many bonds are not frequently traded. This implies that market data for these bonds are missing. This lack of data represent a problem for financial risk measures such as Value at Risk (VaR). This research provides the framework for the construction of a proxy...master thesis 2020
