Frequentistische en Bayesiaanse statistiek in de forensische statistiek

Swanenburg, Jade (author)

In de statistiek zijn er verschillende methodes voor het uitvoeren van model selectie. Het verschil in deze methodes komt voort uit het verschil in stromingen. Voor niet-geneste model selectie zijn de meest ganbare stromingen de Bayes Factor en de likelihood ratio. D. M. Ommen en C. P. Saunders presenteerden theoretische resultaten voor de...

Reinforcement Learning for minimizing the total waiting time of passengers in a Taxi Dispatch Problem

Martens, Vera (author)

A Taxi Dispatch Problem involves assigning taxis to requests of passengers who are waiting at different locations for a trip. In today's economy and society, the Taxi Dispatch Problem and other transport problems can be found everywhere. Not only in transporting people, but also in food delivery from restaurants and package delivery for all kind...

Primitiveren met elementaire functies

Vonk, Maarten (author)

In dit bachelor eindproject kijken we naar de integreerbaarheid van eindige elementaire functies. Soms heb je het vermoeden dat een functie geen primitieve heeft in eindige termen, maar dan is dat vaak lastig om te bewijzen. Aan de hand van de stelling van Liouville-Rosenlicht gaan we in een aantal van zulke gevallen bewijzen dat de gevraagde...

Landens transformatie: De verbinding tussen π, het RMG en de bètafunctie

Frank, Abel (author)

Eerst introduceren we het rekenkundig-meetkundig gemiddelde (RMG), een snel convergerend algoritme dat een verband heeft met π en nog veel meer constanten en functies. Hoffmann toont dit in een bewijs aan, echter is deze niet waterdicht en amper onderbouwd. Daarom gaan wij ons verdiepen in dit bewijs en met name een stap die twee ogenschijnlijk...

Analysis of a streaming video feed of a pulverized coal injection system

Smilde, Elsemiek (author)

Danieli Corus supplies tailor-made solutions for the global steel industry. Cameras are used in tuyeres of blast furnaces to detect physical aspects and irregularities. No operator could monitor those videos all day, which is why video analyses are needed. A program is written to analyse a test video and give information about the temperature,...

Axiomatic Projective Geometry

Haakma, Emiel (author)

Starting with the three axioms of projective geometry, this paper explores concepts such as perspectives, projective maps, and harmonic additions that are unique to this geometry. In addition, important theorems such as Pappus's Theorem, Desargue's Theorem, and the Fundamental Property are mentioned and worked with extensively.

Is de bandit-methode een verbetering op de klassieke methode van A/B-testen?

Lückerath, Femke (author)

In dit onderzoek zijn twee manieren van A/B-testen met elkaar vergeleken. A/B-testen is het vergelijken van verschillende website versies om te achterhalen welke versie voor een hogere opbrengt zorgt. Consumenten krijgen afzonderlijk meerdere versies van een website te zien: versie A, versie B, versie C, et cetera. De websites verschillen op...

Duality in interacting particle systems out of equilibrium

Wiarda, Sjoerd (author)

In this thesis we study a class of interacting particle systems sharing a duality property. This class includes the Symmetric Inclusion Process (SIP(2k)), the Symmetric Exclusion Process (SEP(2j)) and the Independent Random Walkers (IRW). When these systems are in equilibrium (namely they are isolated from the exterior) they admit stationary...

Analysis of the impact of news on the financial market

Dijkstra, Sjoerd (author)

In this work we set out to determine the impact, if any, of the analysis of news on stock price prediction, that is, are we able to predict stock movements more accurately on a consistent basis than a proposed baseline or random guessing on the basis of news’ text analysis. We considered a methodology to be more accurate if its success rate is...

Predicting Football Outcomes: with Bayesian Networks

van Dijk, Max (author)

In this thesis Bayesian Networks are used to predict European football matches between the years 2008 and 2016. The goal of this research is to see how the structures learned by different Bayesian Network learning algorithms influences the predictions. First the data is explored and modified to be used for Bayesian Networks and secondly the...

Extraction of biological parameters of wound-healing processes from time-lapse videos

Tsang, Daniel (author)

Experimental data have been extracted from wound-healing time-lapse videos. These data include the detection of the area of the wound and the detection of individual cells. Extracting the area of the wound is done by using a function in Python OpenCV called cv2.findcontours. An improved method to extract the area of the wound is introduced as...

Optimisation Models for Merging Ambulance Regions in the Netherlands

Zwep, Louise (author)

This thesis focuses on optimising the Emergency Medical Services (EMS) in the Netherlands. In the current situation, the Netherlands is divided into 24 independent regions in which ambulances operate. These regions can be merged in order to reduce response time and increase efficiency. Different models are presented in which these regions are...

Properties of the Racahpolynomials with regard to the Lie algebrarepresentation of sl(2;C)

Mol, Jan (author)

The Racah polynomial Rn(λ(x)) is a polynomial of degree n and is variable in λ(x). In this thesis two properties of this polynomial will be studied. One is the orthogonal property of the Racah polynomial. And the other is that the Racah polynomial can also be described as a polynomial of degree x and variable over λ(n). The Racah polynomials...

On random tridiagonal matrices and the beta log-gas

Breunissen, Rens (author)

In this thesis the beta log-gas probability density function is discussed. It is shown that there is a strong link between this density function and Jacobi matrices. A change of variables exercise shows that the distribution of eigenvalues is exactly like the quadratic beta log-gas. The change of variables gives the normalization constant for...

Annualized hours: Comparing an exact optimization model with its approximation

Bouwmeester, Marjolein (author)

In this thesis, we propose two mixed integer linear program formulations for an optimization problem that incorporates annualized hours: an exact one and an approximation. The objective of our model consists of three weighted parts: a part which minimizes the difference between working hours and contract hours for each employee per week, a part...

A general analysis of change-point methods

El Ouasgiri, Mohammed (author)

The primary goal of this report is to provide a general overview of offline change-point literature as it is known today. Change-point methods are important statistical problems, where we are interested in determining whenever a certain data-set changes in structure. Furthermore, the term "off-line" is meant to indicate that the data itself is...

Asymptotic distribution of the number of monochromatic arithmetic progressions in random colourings of the integers

Rissalah, Abdellah (author)

In this thesis we research arithmetic progressions in random colourings of the integers. We ask ourselves how many arithmetic progressions are contained in zero density subsets of the integers? And what is the asymptotic distribution of the number of arithmetic progressions? Key motivation for this research are the famous results of Van der...

Dependence Measures in Citation Analysis: The application of parametric copulas to capture the dependence structure between the publications of a reseacher and the citations of those publications.

Bachasingh, Ashni (author)

In this thesis we try to capture the dependence structure of the publications of a scholar and the citations of those publications via copulas. To do so, we will use a sample of Quebec re- searchers for who their publication amount as well as their citation amounts are known. We are provided with multiple variables concerning citation. We study...

Voor grote random matrices bestaat er een verband tussen de eigenwaarden van deze random matrices en halve cirkels. Om meer precies te zijn bestaan er voor random matrices die aan een aantal voorwaarden voldoen een vorm van convergentie tussen de verdeling van eigenwaarden van de matrices en een halve cirkel verdeling. Een stelling die deze...

Comparing Sequential and Cooperative Erasure Repairing

ten Hagen, Erik (author)

Information is spatially distributed over data servers and for many services online it has to be available at all times, but those servers are not always available. If we store the information in a smart way, we might be able to still get our information even if we can not reach the servers.<br/>There are two factors we have to keep in mind when...
