Growe, Kevin (author)In the end of November 2018 the InSight mission landed on the Martian surface deploying a six axis broadband and short period seismometer, in order record marsquakes and ambient noise, which can be used to constrain the deeper interior structures of the planet. In this study we process the three components of the broad band seismometer and apply...master thesis 2021

Boon, Cindy (author)Measuring variable importance is often a difficult task: among others models can be complex and covariates can interact with each other and can be correlated. This study focuses on two questions: First, what should be the theoretical measure of variable importance under a given data-generating model? And second, what are the best estimates of...master thesis 2021

Trevnenski, Georgi (author)Video summarization is a task which many researchers have tried to automate with deep learning methods. One of these methods is the SUM-GAN-AAE algorithm developed by Apostolidis et al. which is an unsupervised machine learning method evaluated in this study. The research aims at testing the algorithm's performance on the Breakfast dataset,...bachelor thesis 2021

Goverse, Vincent (author)In this thesis, we start with giving a mathematical description of bipartite quantum correlations and how they are built up in the Tensor model. This is needed because we want to recover the state and the operators when only the bipartite quantum correlation is known. In the literature, there are see-saw algorithms to...bachelor thesis 2021

Kindermann, Paulina (author)Since 2017, Dutch flood defences are assessed according to new safety standards. These standards are based on flooding probabilities and rely on several assumptions and approximations. There are concerns that the combination of these assumptions leads to conservative results. Recently computed probabilities of failure are...master thesis 2021

Deshpande, Parth (author)Use of earth observation satellites have grown at a very high rate over the past few decades. On a closer observation of things around, most of them uses satellites, directly or indirectly. Satellites are being used in the day-to-day life without being aware of its application. Satellites are used for small things like weather report,...master thesis 2021

Jonkman, Niels (author)We study the impact of wrong-way risk (WWR) on the credit valuation adjustment (CVA) of a portfolio of interest rate swaps (IRSs), using an intensity-based reduced form model. To model WWR in IRSs we create a dependence between he underlying market risk factor of the IRS and the survival probability of the <br/>counterparty. The focus lies on...master thesis 2021

Application of geo-statistics and pairwise established CPTbased correlations for line infrastructureLengkeek, H.J. (author), Jonkman, Sebastiaan N. (author), Kanning, W. (author)Parameter determination is the first step in geotechnical engineering. Engineers are often confronted with limited data, large variations and different types of tests, both in-situ and laboratory tests. Within this complex setting, Codes require cautious estimates, so called characteristic values, preferable substantiated with observations and...conference paper 2021

Castro, Saullo G.P. (author), Almeida Jr., J.H.S. (author), St-Pierre, Luc (author), Wang, Z. (author)Measuring the geometric imperfections in cylindrical shells is a critical step necessary to create accurate numerical models that can capture the imperfection-sensitive behavior of these structures. Modern composite structures, such as variable–angle filament–wound (VAFW) cylinders, have a unique imperfection signature that is still unknown to...journal article 2021

Srinivasa Raja, A. (author), de Boer, Pascal (author), Giepmans, Ben N.G. (author), Hoogenboom, J.P. (author)Electron microscopy is crucial for imaging biological ultrastructure at nanometer resolution. However, electron irradiation also causes specimen damage, reflected in structural and chemical changes that can give rise to alternative signals. Here, luminescence induced by electron-beam irradiation is reported across a range of materials widely...journal article 2021

Hosseini-Asl, Mahin (author), Amiri Simkooei, A. (author), Safari, Abdolreza (author)High precision geoid determination is a challenging task at the national scale. Many efforts have been conducted to determine precise geoid, locally or globally. Geoid models have different precision depending on the type of information and the strategy employed when calculating the models. This contribution addresses the challenging problem...journal article 2021

Aljuffri, A.A.M. (author), Zwalua, Marc (author), Reinbrecht, Cezar (author), Hamdioui, S. (author), Taouil, M. (author)Side-channel attacks (SCAs) are powerful attacks that could be used to retrieve keys from electronic devices. Several physical leakage sources can be exploited in SCAs, such as power, time, heat, and so on. Heat is one of the side-channels that is not frequently analyzed by attackers in the literature due to the high noise associated with...journal article 2021

(author)We present a software package for single-dish data processing of spacecraft signals observed with VLBI-equipped radio telescopes. The Spacecraft Doppler tracking (SDtracker) software allows one to obtain topocentric frequency detections with a sub-Hz precision and reconstructed and residual phases of the carrier signal of any spacecraft or...journal article 2021

(author)The coupon specimen with a transverse butt weld in the middle could be used for determining local constitutive properties of the heat-affected zone (HAZ) and the weld metal (WM) based on the digital image correlation (DIC). However, limited research is reported to demonstrate how to identify the boundary of each region in DIC results....journal article 2021

Rigotti Manesco, A.L. (author), Lado, Jose L. (author)Quasi-flat-bands emerging in buckled monolayer graphene superlattices have been recently shown to realize correlated states analogous to those observed in twisted graphene multilayers. Here, we demonstrate the emergence of valley topology driven by competing electronic correlations in buckled graphene superlattices. We show, both by means of...journal article 2021

(author), Hoogenboom, J.P. (author)Large-scale electron microscopy (EM) allows analysis of both tissues and macromolecules in a semi-automated manner, but acquisition rate forms a bottleneck. We reasoned that a negative bias potential may be used to enhance signal collection, allowing shorter dwell times and thus increasing imaging speed. Negative bias potential has previously...journal article 2021
