Vonk, M.A. (author), Collenteur, Raoul A. (author), Panday, Sorab (author), Schaars, Frans (author), Bakker, M. (author)The performance of time series models is assessed using synthetic head series simulated with a numerical model that solves Richards' equation for variably saturated flow. Heads were simulated in a homogeneous unconfined aquifer between two parallel canals; measured daily precipitation and potential evaporation are specified at the land...journal article 2024

Vonk, Renzo (author)The COVID-19 pandemic has highlighted the importance of indoor air quality in preventing the spread of airborne transmissive diseases. Offices are some of the largest hotspots for disease transmission. To address this issue, a joint venture between FLEX/design and Euromate, called ‘X-Lair,’ aims to design an air purifier specifically targeting...master thesis 2023

Vonk, Martijn (author)Autonomous vehicles (AVs) can solve a lot of problems related to traffic safety, comfort and congestion. While the sensors used by these vehicles are getting cheaper, more accurate, and software is improving, the first completely automated vehicle does not exist yet. When AVs start gradually driving on the roads, there will be a mixed traffic...master thesis 2023

Taale, Henk (author), Wilmink, Isabel (author), Vonk, Tanja (author)Within the area of mobility much discussion is going on about human well-being and how mobility can contribute to that. Human well-being is about everything what influences the well-being of people, in the broadest sense. It is about welfare beyond the Gross Domestic Product (GDP). Mobility makes a valuable contribution to the welfare and well...conference paper 2023

(author)In recent years, quantum dots (QDs) have emerged as bright, color-tunable light sources for various applications such as light-emitting devices, lasing, and bioimaging. One important next step to advance their applicability is to reduce particle-to-particle variations of the emission properties as well as fluctuations of a single QD’s...journal article 2023

(author)Indium phosphide colloidal quantum dots (CQDs) are the main alternative for toxic and restricted Cd based CQDs for lighting and display applications. Here we systematically report on the size-dependent optical absorption, ensemble, and single particle photoluminescence (PL) and biexciton lifetimes of core-only InP CQDs. This systematic study...journal article 2023

Vonk, Stefan (author)Polymeric micelles are increasingly used in chemotherapy. To get a greater understanding of the behaviour of these micelles is important. Nuclear imaging, such as SPECT and PET can provide relevant information about the behaviour of the micelles. However, to use these techniques, the micelles must be radiolabelled. In this thesis a chelator free...bachelor thesis 2022

Vonk, Arjan (author)Mapping an environment with a Light Detection and Ranging (LiDAR) sensor through the use of a LiDAR Simultaneous Localization And Mapping (SLAM) algorithm is a powerful technology that allows for the creation of detailed 3D models. Recently various LiDAR sensors have been developed based on Micro-Electro-Mechanical System (MEMS) technology....master thesis 2022

Brakenhoff, Davíd A. (author), Vonk, M.A. (author), Collenteur, Raoul A. (author), Van Baar, Marco (author), Bakker, M. (author)In 2018–2020, meteorological droughts over Northwestern Europe caused severe declines in groundwater heads with significant damage to groundwater-dependent ecosystems and agriculture. The response of the groundwater system to different hydrological stresses is valuable information for decision-makers. In this paper, a reproducible, data-driven...journal article 2022

Vonk, Martin (author)Transfer function noise (TFN) modelling is a form of time series analysis which regularly uses the recharge as a stress to explain the groundwater table fluctuations. Often the recharge flux is estimated as a linear combination of the precipitation and the (potential) evaporation. However, this is a simplification of the actual hydrological...master thesis 2021

(author)Broadening of multiexciton emission from colloidal quantum dots (QDs) at room temperature is important for their use in high-power applications, but an in-depth characterization has not been possible until now. We present and apply a novel spectroscopic method to quantify the biexciton line width and biexciton binding energy of single CdSe...journal article 2021

Vonk, Michiel (author)To fight increasing traffic in city centres, tunnelling can be used to move traffic under the surface of the busy city. However, to prevent damage to the surrounding buildings, the settlements induced by the tunnelling should be kept to a minimum. This thesis researches the influence of the TBM tail void and its grouting process on the...master thesis 2020

Vonk, Michiel (author)More and more devices are gaining some form of smartness either by sensing their environment on their own or by communication. An example of this is Smart Lighting, a field in which Chess Wise is active for over 6 years. By adding sensors and communication lighting can be controlled more efficiently. For example motion sensors to turn off...master thesis 2020

The appeal of these materials is largely due to the robustness of the optoelectronic properties to structural defects. The photoluminescence quantum yield (PLQY) of most types of perovskite...journal article 2020

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...bachelor thesis 2019
