Duffy, jill (author)The Leslie model considers age-specific birth and survival rates to describe how a population size and age distribution changes over time. This thesis investigates the long-term dynamics of the Leslie model for population growth, utilizing mathematical theorems such as Perron-Frobenius, Doeblin’s theorem, and Branching processes. <br/><br/>The...bachelor thesis 2023

Corak, Nino (author)One possible way of proving the famous and important Riemann hypothesis would be to realize the Riemann zeta zeroes as the eigenvalues of some self-adjoint operator, using self-adjointness to show that the non-trivial zeroes all lie on the critical line. This is known as the Hilbert-Polya conjecture. Interpreting such a self-adjoint operator as...bachelor thesis 2023

Agnihotri, Nisha (author)Erasmus MC is conducting a study on the increased risk of cardiovascular disease in women who have migraine. For this purpose, 50 healthy women and 50 women with migraine in age category of 40-60 years were compared using measurements of their dermal blood flow.<br/>These measurements are done using two different imaging devices: Laser Speckle...bachelor thesis 2023

Hemler, Frederique (author)Velotech Solutions (VTS) is a company specialised in detecting damages in public spaces, such as road damages, non-working light posts or crooked traffic signs. This detection happens by bike or by car, and covers every street in the city or neighbourhood. The routes for navigation are currently created by hand. In this thesis, a proposal is...bachelor thesis 2023

van der Meer, Fos (author)This report investigates a scheduling problem where task duration is uncertain. The duration per task has a lower and upper bound, and is dependent on observed duration of other tasks. This tries to closer model real life. We reduce all possible different outcomes to a few extreme scenarios. The report compares two types of heuristcs: one which...bachelor thesis 2023

Ahmad, Amna (author)The Bayesian approach is a very important approach for tackling problems in statistics. It involves choosing a distribution that reflects the prior knowledge and thus takes all knowledge into account in contrast to the frequentist approach. It also assumes that the parameters (the regression coefficients) follow a distribution called the...bachelor thesis 2023

Molendijk, Thomas (author)The k-truncated metric dimension of a graph is the minimum number of sensors (a subset of the vertex set) needed to uniquely identify every vertex in the graph based on its distance to the sensors, where the sensors have a measuring range of k. We give an algorithm with the goal that given any tree and any value for the measuring range of the...bachelor thesis 2023

Riemens, Noud (author)Upper bounds for the kissing number can be written as a semidefinite program (SDP) through the Delsarte-Goethals-Seidel method for spherical codes. This thesis solves the resulting SDP with a cutting plane approach, in which a sequence of linear programs (LPs) is solved with the addition of linear constraints every round. We study the...bachelor thesis 2023

Bonenkamp, Jasper (author)Ever since their discovery, the Trojans have raised many questions among astrophysicists. In 1989 it was found that there were more L4 than L5 Trojans and the current L4:L5 ratio value is estimated to be 1.6. However, this asymmetry could not be explained by Jupiter’s current orbit and must therefore have arisen during the early development of...bachelor thesis 2023

Schermerhorn, Rick (author)In this report we examine the dual space of $\ell^\infty$. If $p \in [1,\infty)$ and $q \in [1,\infty]$ satisfy $\frac{1}{p}+\frac{1}{q}=1$, then one can identify the spaces $\ell^q$ and $(\ell^p)'$ in a natural way via an isometric isomorphism. This identification does not extend to the case $p=\infty$ and $q=1$. We prove that the obvious...bachelor thesis 2023

Roos, Matthijs (author)To better understand the formation of stars in dusty star-forming galaxies (DSFGs), and the evolution of this type of submillimeter galaxies (SMGs), it is of high significance to perform submillimeter/far-infrared surveys. The Deep Spectroscopic High-redshift Mapper 2.0 (DESHIMA2.0) on the ASTE telescope in Chile has been designed to observe the...bachelor thesis 2023

Chang, Moohyun (author)In his paper, Conway presents his remarkable findings, leaving the task of careful examination and verification to us. He unveils a special link between the extraFib series and the Empire State Building, and reveals an unexpected relationship between Fibonacci numbers, Lucas numbers, and trigonometric formulas. This fresh concept, labeled ...bachelor thesis 2023

van der Waal, Leon (author)The Lovász theta function, and the variants of it given by Schrijver and Szegedy are upper bounds on the independence number of a graph. These functions play an important role in several optimization problems, such as the Cohn-Elkies bound for optimal sphere packing densities.<br/><br/>This thesis covers the properties of these functions. The...bachelor thesis 2023

Tomassen, Niels (author)This research explores the size variations of artifacts in Maven Central, a repository containing a large collection of Java artifacts. This analysis sheds light on the coding habits and dependency management ecosystems within Maven Central, emphasizing the importance of managing artifact sizes effectively. It also provides valuable insights to...bachelor thesis 2023

Dahoe, Gaurish (author)Each violin generates a unique sound with a distinct set of acoustic properties. In particular, the Stradivarius violins are said to have a very unique sound. The ultimate goal of this thesis is to aid in recreating the unique sound of the Stradivarius. Though, the field of research surrounding the violin and its acoustic properties is very...bachelor thesis 2023

Cheng, Shukun (author)Causal inference is a widely recognized concept in various domains, including medicine, for estimating the effect of a medication on a certain disease. During this estimation, overlap is commonly used to eliminate the error caused by other features. However, finding the real overlap region in practice is challenging due to the limited sample...bachelor thesis 2023

Speksnijder, Robert (author)Quantum random walks are the quantum analogs of classical random walks and appear to be promising tools to design fast quantum algorithms. Therefore it is important to study their time-related features and see how these differ compared to the classical case. For the discrete-time quantum walk on the line it has been shown that the probability to...bachelor thesis 2023

Ramdin, Keane (author)There has been interesting research on the superconducting diode recently. A possible structure for this is the Superconductor/Ferroelectric/Superconductor (S/FE/S) Josephson junction. Our goal is to simulate a S/FE/S junction with a magnetic field and see if this leads to a superconducting diode effect. First this junction and its properties...bachelor thesis 2023

Wessels, Morten (author)"Who do you want to sit next to?'' In this thesis we develop an algorithm that optimizes a classroom lay-out based on this question. Besides the couples that sit next to each other, it also matters who sits in front (or behind). Even the relations across the aisles matter in the lay-out optimization. Each student chooses three other students and...bachelor thesis 2023

Benjert, Zylan (author)We consider the problem of random walks moving around on a lattice Zd with an initial Poisson distribution of traps. We consider both static and moving traps. In the static case, we prove that the survival time has a decay of e−c t d /d +2 based on a heuristic argument. In the moving case we aim to prove the sub-exponential...bachelor thesis 2023
