Goudswaard, Reef (author)This bachelor's thesis explores the realm of map projections, aiming to establish a systematic approach for evaluating and ranking them based on angular and area distortions. Beginning with a definition of map projections, the study progresses to quantify the distortions that occur when projecting a spherical surface onto a flat one. Using these...bachelor thesis 2024

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

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

Sleijfer, Josh (author)Humans are efficient at moving due to their exceptional mastery of bipedal locomotion. Several models have been made that attempt to model the motion of the centre of mass with a springmass system with various degree of success. For example, a two dimensional model tracks the height of the centre of mass well and a three dimensional model...bachelor thesis 2023

de Nijs, Joost (author)The rotational velocities of stars in galaxies indicate that either Newtonian gravity breaks down on this scale, or that there is extra mass in the universe that has not been observed. The former is known as Modified Newtonian Dynamics (MOND), whereas the latter option is known as the dark matter paradigm. In this thesis a version of MOND is...bachelor thesis 2023

Koks, Jort (author)This research investigates the impact of gravitational scatterings caused by close encounters between particles in an <i>N</i>body Kepler system, addressing three main questions: (1) the influence of scatterings on system evolution, (2) the correspondence between simulated and expected average times between scatterings, and (3) the effect of...bachelor thesis 2023

Gort, Timo (author)<i>Context.</i> In the nearfuture, exoplanets can be observed directly through telescopes. Although the resolution of the planet's image will only be one pixel at first, the intensity of this pixel will change over time because of the orbit around its host star and its diurnal rotation. This intensity as a function of time is called the light...bachelor thesis 2022

Moorlag, Martijn (author)This report has been made to gain more insight and knowledge of the Keplerian method for collision detection simulations by simplifying Nbody systems to a list or particles with orbital parameters. Collision detection is an essential part in modeling the evolution of protoplanetary disk becoming planetary systems by the merging of planetesimal...bachelor thesis 2022

Aliberti, Dylan (author)The aim of this thesis was to test the efficiency in practice of an analytical propagator with collision detection for <i>N</i>body Keplerian systems. This can be used to simulate the evolution of a protoplanetary disk, which gives insight into how planetary systems form. The analytic propagator calculates collisions one by one, while a...bachelor thesis 2022

Mulder, Tim (author)This thesis develops a method to map the surface of an exoplanet. The problem of exoplanet mapping sounds easy to solve. Take a few photographs of an exoplanet and sew them together to create a map of the surface. The telescope required to do this is far beyond our technological capabilities. However, our current telescopes could allow us to...bachelor thesis 2022

Blanken, Sweder (author)In the near future, nextgeneration telescopes will be able to observe Earthlike exoplanets illuminated by their parent stars for long periods of time. As the distance between exoplanet and observer is enormous, exoplanets will only make up a pixel on our image. However, the observed intensity of this pixel will fluctuate over time as the...bachelor thesis 2022

Liu, Darwin (author)The Bullet Cluster is a galaxy cluster, which is often used as evidence for dark matter [10]. In this thesis, Modified Newtonian Dynamics (MOND) is studied for various interpolation functions on a model of the Bullet<br/>Cluster. MOND is a theory proposed by Milgrom which modifies the Newtonian gravity law, such that it explains the flat...bachelor thesis 2022

Hajer, Wouter (author)Over the past century various different discrepancies in the expected and observed behaviour of galaxies and galaxy clusters were found. Together this is called the missing mass problem and the most well known theory trying to explain these differences states that there is additional undetectable mass in the form of dark matter. Modified...bachelor thesis 2022

Schouten, Aron (author)Context: In astronomy, collision detection is the computational problem of finding when planets, asteroids or satellites collide. Computer simulations make it possible to show very precisely how bodies move through space, which makes it possible to detect collisions. However, these simulations require a lot of computing power if there are many...bachelor thesis 2022

van Leeuwen, Ella (author)The Atmoscope is the idea to use the atmosphere of a planet as a telescopic lens. It uses the refractive properties of an atmosphere to converge light rays to a focal line. It has been hypothesized that using Earth’s atmosphere could, under favorable circumstances, yield an amplification of 55; 000 for a detector that has a surface area of 1m2....bachelor thesis 2022

Kamminga, Thomas (author)The observations of the Event Horizon Telescope led to the first mages of a black hole, an object with so much gravity that not even light can escape it. These images remain fuzzy but clearly show the shadow of a black hole with a bright disk and will only improve in quality over time. We want to be able to deduce, from the images, the following...bachelor thesis 2022

Soliman, Philip (author)This thesis contains the development of continuous Kepler orbit and a discrete numerical integrationbased collision detection algorithms in a system of LEO satellites, which in combination with collision algorithm form a simplified space debris evolution model. This model is then used to study the Kessler syndrome. The continuous and discrete...bachelor thesis 2022

Schokker, Odessa (author)In this thesis Modified Newtonian Dynamics (MOND) is explored in galaxy clusters similar to the Virgo cluster. MOND is a theory proposed to explain the flat rotation curves of galaxies and the velocities of galaxies within galaxy clusters, as an alternative to the Dark Matter (DM) model. MOND states that Newton’s law of gravitation is incorrect...bachelor thesis 2022

Stuger, Samuel (author)In this thesis, we provide a method for reconstructing a planet's surface map from its reflected light curve. We are going to derive an equation for the reflective lightcurve under the assumption that the surface map is characterized by four different surface types (ocean, vegetation, sand and snow), is stationary (no clouds), and that all...bachelor thesis 2021
