Swanenburg, Jade (author)This thesis aims to develop a methodology for predicting the swap spread, which is defined as the difference between the German government bond interest rate and the Euribor swap rate. Thus far, the prediction of interest rates is limited to the prediction of a single interest rate. This thesis introduces the simultaneous prediction of the...master thesis 2023

ten Klooster, Fons (author)Research in passive Heating, Ventilation, and Air Conditioning (HVAC) systems has gained traction over the last few years. Although passive HVAC is not a new concept, advances in environment sensing, control methods, and hardware have made it a more viable method. Some difficulties still exist, such as optimal sensor placement and optimal...master thesis 2022

Pieters, Marc (author)This thesis describes an experiment investigating the effects of motion filter order on human manual control tracking behavior and performance. The experiment was performed on two simulators: the Vertical Motion Simulator at NASA Ames Research Center and the SIMONA Research Simulator at Delft University of Technology. Eighteen pilots in the...master thesis 2018

Chitchian, M.M. (author)The particle filter is a Bayesian estimation technique based on Monte Carlo simulations. The non-parametric nature of particle filters makes them ideal for non-linear non-Gaussian systems. This greater filtering accuracy, however, comes at the price of increased computational complexity which limits their practical use for real-time applications...master thesis 2011

de Jong, David (author)End-to-end trained Convolutional Neural Networks have led to a breakthrough in optical flow estimation. The most recent advances focus on improving the optical flow estimation by improving the architecture and setting a new benchmark on the publicly available MPI-Sintel dataset. Instead, in this article, we investigate how deep neural networks...master thesis 2020

De Koning, D. (author)This thesis discusses the applicability of assimilation of artificial SMAP data into a quasi steady state hydrological model to improve soil moisture estimates. The model used for this research was SIMGRO and since no real SMAP data were available at the time of the research, artificial SMAP data were used. The ensemble Kalman filter was used to...master thesis 2015

Van der Horst, T. (author)The dynamics of systems can be analysed by combining the dynamics of its components. This method is generally know as dynamic substructuring. It allows for efficient computation of the dynamics of structures that would otherwise be to complex to determine. Most dynamic substructuring approaches use the frequency domain for the re-assembling of...master thesis 2014

Beers, Karlijn (author)This thesis explores the usage of the particle filter as a data assimilation technique to estimate subsurface processes, such as reservoir volume change from space-geodetic PS-InSAR surface measurements. The specific research area is Groningen, where subsidence is induced by hydrocarbon and salt production.<br/>The satellite radar PS-InSAR...master thesis 2018

Kou, Lantian (author)The particle filter (PF) algorithm is appropriate to solve the problem of speaker tracking in a reverberant and noisy environment using distributed pairwise microphone networks. First, complete the tracking task based on PF algorithm in centralized manner, a processing center is required to collect the signal from all microphones to carry out...master thesis 2019

van Groeningen, Tom (author)When the re brigade arrives at a burning building, it is of vital importance that people who are still inside can quickly be found. In this thesis we contribute to an ultrasonic sound sensor for human presence detection in smoke-lled spaces. This type of sensor could assist the re brigade when evacuating a large building by directing them to the...master thesis 2018

Agung Kusumawardhana, Agung (author)A reverse osmosis (RO) membrane followed by a packed tower aerator and rapid sand filter are used by an agricultural company in Emmen to treat brackish groundwater to supply water for growing crops and cleaning purposes. The iron removal by the treatment plant is sufficient most of the time throughout the year. However, the farmer periodically ...master thesis 2021

Van Ginkel, J.N. (author)Electronic stability control (ESC) has been shown to reduce the accident rate in a number of situations. Therefore, it is important to keep improving ESC and other control systems. One way to do this is by improving the available information on the state of the vehicle and its environment. The tire-road friction coefficient µ is particularly...master thesis 2014

van Oorschot, Marijn (author)Spacecraft navigation and control is difficult in deep space operations. Especially around asteroids, the irregular gravity field increases the difficulty of estimating the spacecraft trajectory. Autonomous navigation can increase the safety and accuracy for orbit proximity operations. Furthermore, it eliminates the need for continuous...master thesis 2022

Amin, H.H.N. (author)One of the first mathematical models to describe the interest rate over time was the Vasicek model (1978). Soon after, the Cox Ingersoll Ross (CIR) model (1985) was introduced. The Vasicek model and the CIR model belong to the family of short interest rate models. Through transformation these models can be applied to compute the interest rate...master thesis 2012

Tanis, Tobias (author)Autonomous orbit determination could help reducing the growing load on ground-based deep space networks. For small satellites, orbit determination based solely on inter-satellite measurements could be a strong alternative for conventional ground-based navigation support. The possibilities of this autonomous orbit determination method are...master thesis 2022

Tsompanopoulos, E. (author)Based on satellite observations of Earths time variable gravity field from the Gravity Recovery and Climate Experiment (GRACE), it is possible to derive variations in terrestrial water storage. Tiny variations of gravity from monthly into a decade time scales are mainly due to redistributions of water mass inside the surface fluid envelops of...master thesis 2010

Zilko, A.A. (author)Lately, the objective of reservoir engineering is to optimize hydrocarbon recovery from a reservoir. To achieve that goal, a good knowledge of the subsurface properties is crucial. The author is concerned with estimating one of the properties of the field: the permeability of a reservoir. To characterize the fluid flow, a two phase (oil-water)...master thesis 2012

Jansens, R. (author)Filterconstructies hebben als doel constructies te beschermen tegen uitspoeling van grond en beschadiging door wateroverdrukken. Een granulaire filterconstructie bestaat uit een ofmeer lagen van granulairfiltermateriaal, die het onderliggende, loskorrelige basismateriaal tegenhoudt, maar het water doorlaat. Meestal wordt het criterium gehanteerd...master thesis 2000
