Snijders, Hanne (author)In the realm of fluid dynamics and particle transport, the control of particle trajectories represents a formidable challenge. It would be useful to be able to optimally navigate an oceanographic float from one pre-set location to another by solely changing its buoyancy. In this thesis, a first step in discovering whether this is possible and...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

Swinkels, Bart (author)The "Number Hides Game" (NHG) is 2-player game played on a board that consists of a row of p consecutive coins. Player I and player II simultaneously choose subsets of m and n consecutive coins respectively. Player II pays the number of coins that lie in the intersection of the subsets to player I. This thesis introduces basic knowledge from the...bachelor thesis 2022

Perrenet, Joris (author)The goal of seismic imaging is to create a model of the subsurface from samples of a transmitted wavefield that is reflected in soil layers.<br/>The created model can be used to locate storage possibilities for CO2 or H2 or to find oil and gas reservoirs or other natural resources.<br/>Seismic imaging relies on the propagation of wavefields,...bachelor thesis 2022

Veenman, Victor (author)Due to human advancement in recent centuries, extinction rates of animals and plants around the earth have greatly risen. Conservation biology, the study of conservation of nature and earth’s biodiversity, aims to protect species from these increasing extinction rates.<br/>Phylogenetic diversity is a measure for biodiversity that can help in...bachelor thesis 2022

Sjerps, Thomas (author)Chromostereoscopic images encode depth as colour, with the red part of the visible spectrum encoding nearby depths and the blue part encoding far-away depths. However, when encoding a regular image with its depth, the generated colours may not match with the original colours in the image. Following a user study, a technique has been developed...bachelor thesis 2022

Kowalewski, Przemysław (author)STOKE is one of the Superoptimizers which are programs that given a function and a set of instructions of a processor, traverse through a space of programs that compute a given function and try to find the optimal usually in terms of execution speed or size of the binary. Authors of STOKE make some extraordinary claims. They suggest that it is...bachelor thesis 2022

van de Lest, Pim (author)In this thesis, a simulated annealing algorithm is implemented to optimize the efficiency of a tandem solar cell. The efficiency of a tandem solar cell is approximated by the current of the tandem solar cell. This current is determined by the simulation program GenPro4. Firstly, the general concepts of simulated annealing is described. After...bachelor thesis 2021

de Vries, Olaf (author)In this work, Clebsch-Gordan coefficients are studied from both a quantum mechanical and a mathematical perspective. In quantum mechanics, Clebsch-Gordan coefficients arise when two quantum systems with a certain angular momentum are combined and the total angular momentum is to be found. We start by discussing the relevant postulates of quantum...bachelor thesis 2021

Bosma, Jan (author)The first part of this thesis provides a mathematical description for bipartite quantum correlations, aiming to analyze the geometry of several sets of correlations. We explain why quantum entanglement can be used to simulate shared randomness: C<sub>loc</sub>(Γ) ⊆ C<sub>q</sub><sup>d</sup>(Γ) for a sufficiently large d. The known bound for this...bachelor thesis 2020

Bus, J.C.P. (author)The Quantum Approximate Optimization Algorithm (QAOA) is one of the promising near-term algorithms designed to find approximate solutions for combinatorial optimization problems. The algorithm prepares a parametrized state that is aimed to maximize the expectation value of the objective function of the problem. The circuit for QAOA consists of p...bachelor thesis 2020

van Hemert, G. (author)Storage systems, such as Flash memories, suffer, apart from the always present<br/>noise, also from offset. The presence of this noise can decrease the performance<br/>of a decoder using the Euclidean distance significantly. To negate the effects of<br/>offset, a new distance, the modied Euclidean distance, was introduced, which<br/>offers...bachelor thesis 2020

Jansen, S.E.D. (author)This thesis deals with n-to-1 entanglement distillation protocols for bipartite quantum systems in a group theoretical setting. The local operations in the protocols are restricted to Clifford operations. An efficient representation of the elements of the Clifford group in terms of binary matrices is presented. Moreover, a characterization of...bachelor thesis 2020

Schönfeld, Mariette (author)Machine learning has been a computer sciences buzzword for years. The technology has a lot of potential and a huge number of applications that spoke to people with and without knowledge of computer sciences. Image, text and speech recognition, social profiling, computergames, everything seemed possible. Machine learning is not as much in the...bachelor thesis 2020

Huijsman, Robbert (author)Interest in phylogenetic trees for histories of species and DNA has spawned many problems, one of which is TreeContainment; a problem that asks whether a tree is contained within a network. The TreeContainment problem is proven to be NP-hard for general trees and networks, however it is solvable in polynomial time for networks that meet the tree...bachelor thesis 2019

Ha, Deon (author)With the growing wealth and economy of a country, there are an increasing amount of small and big businesses. Every company has its own marketing strategy that it uses in order to lure customers away from their competition and increase their sales. Choosing the perfect time to advertise or discount several products is of essence for a company to...bachelor thesis 2019

Verzijlbergen, Esmay (author)This thesis provides you with basic information on graph theory as well as phylogenetic networks, it studies the relationship between undirected (unrooted) and directed (rooted) phylogenetic networks, based on the manuscript 'Rooting for phylogenetic networks' . Undirected phylogenetic networks can be oriented to become a directed network. In...bachelor thesis 2019

Buist, Jan Willem (author)In open-pit mining on a bench level, the dig-limit optimization problem is deciding whether to classify a Selective Mining Unit(SMU) as waste or whether to classify it as ore. SMU’s with high ore grades are profitable for the mining operation, but due to equipment size a whole frame of SMU’s has to be classified as either ore or waste. In this...bachelor thesis 2018

Versluis, Nina (author)This thesis concerns the cap set problem in affine geometry. The problem is illustrated by the card game SET and its geometrical interpretation in ternary affine space. The maximal cardinality of a cap is known for the dimension one to six. For the four lowest dimensions, a maximal cap is constructed and the optimality of its size proven. From...bachelor thesis 2017
