Lendering, K.T. (author), Sebastian, Antonia (author), Jonkman, Sebastiaan N. (author)Floods are the costliest and deadliest weather-related disaster globally. With higher population density in flood prone areas, increased urban development, and projected climate impacts, the frequency and severity of flooding in Europe is predicted to rise. While permanent flood defences have been shown to be more economically effective and...abstract 2017

Datema, Tobias (author)In this thesis, we consider the threshold metric dimension problem of graphs, related to and motivated by source detection.<br/>We construct a graph G = (V,E) for a given set of sensors of size m: {s1, s2, ..., sm} and a range k > 0. We want that each node v ∈ V has a unique combination of distances (dk (s1, v),dk (s2, v), ...,dk (sm, v)),...bachelor thesis 2022

Maas, Youri (author)In this thesis we are going to study outlier detection methods and propose a new method. Classical outlier detection is typically based on the assumption that the data is from a Gaussian/normal distribution. When the underlying distribution of a random sample is heavy tailed, so not normal , it is likely to have some extreme observations which...bachelor thesis 2019

Dijkshoorn, Michel (author)In this thesis the theory of depth functions is researched. Depth functions are functions that measure data depth and order multivariate observations. Two depth functions are discussed: the halfspace and simplicial depth function. The halfspace depth of a point is defined as the smallest probability for which a closed halfspace contains that...bachelor thesis 2019

Kirana, M. (author)How disastrous would it be if a flood occurred in your country? Or a Tsunami, earthquake etc... The events above are considered to be 'extreme'. When such phenomena happen the results are usually very destructive, but the probability that such an extreme event occurs is of course very small and might not even occur in an entire lifetime. The...bachelor thesis 2016

Van der Ent, R.J. (author)Het wereldklimaat verandert en het Nederlandse klimaat verandert mee. Wat staat ons de komende eeuw te wachten? Klimaatwetenschappers schetsen het volgende toekomstbeeld: De invloed van de mens op het klimaat zal toenemen waardoor de wereldtemperatuur verder stijgt met 1 tot 6 graden. Meer en hevigere neerslag is dan het gevolg. In Nederland...bachelor thesis 2006

Leeuwestein, Linda (author)In this research, the returns of four cryptocurrencies (Bitcoin, Litecoin, Ripple and Ethereum) were analyzed in order to answer the following research question: “How do the returns of Bitcoin and other altcoins behave over time, and what can we say about extreme values for losses and profits?” With respect to volatility, cryptocurrencies can...bachelor thesis 2018

Velthoen, J.J. (author)In extreme value theory the focus is on the tails of the distribution. The main focus is to estimate the tail distribution for a rounded data set. To estimate this tail distribution the extreme value index should be estimated, but due to the rounded data this extreme value index oscillates heavily. Therefore a correct estimate can not be...bachelor thesis 2014

Den Heijer, C. (author), Reniers, A.J.H.M. (author), Van de Graaff, J. (author), Van Gelder, P.H.A.J.M. (author)Coastal dunes protect low lying coastal areas against the sea. Extreme waves and water levels during severe storms may cause breaching of the dunes. Consequently, serious damage due to flooding and direct wave attack could occur, resulting in loss of life and property. Proper coastal management implies that reinforcement measures will be taken...conference paper 2008

Bierbooms, W.A.A.M. (author), Peeringa, J. (author)Up to now just deterministic gust shapes are specified in standards; e.g. the Extreme Operating Gust (IEC) is given by a Mexican hat like shape. In this paper gust shapes will be determined by application of so-called constrained stochastic simulation. This method specifies how to efficiently generate time series around some specific event (e.g....conference paper 2009

Shi, L. (author), Nihtianov, S. (author), Scholze, F. (author), Gottwald, A. (author), Nanver, L.K. (author)In this paper, the optical and electrical performance of a newly developed silicon photodiode based on pure boron CVD technology (PureB-diodes) is introduced. Due to their extremely shallow p-n junction, with the depletion zone starting only a few nanometers below the surf ce, and nm-thin pure-boron-layer coverage of the anode surface, PureB...conference paper 2011

Spekkers, M.H. (author), Kok, M. (author), Clemens, F.H.L.R. (author), Ten Veldhuis, J.A.E. (author)Intense rainfall may locally cause considerable damage in cities, e.g. because of sewer floods. A better understanding of relationships between rainfall characteristics and rainfall-related damage can help insurers and flood authorities to respond more adequately to rainfall extremes. This paper aims to study to what extent weather radars can be...conference paper 2013

Klopman, G. (author), Stive, M.J.F. (author)As an alternative to a more or less standard derivation procedure for design wave heights in relatively shallow water, two improvements of the procedure are suggested which lead to less conservative results. These improvements are based on observations of shallow water effects on both the decay of total wave energy density and on the extreme...conference paper 1989

Bos, R. (author), Bierbooms, W.A.A.M. (author), Van Bussel, G.J.W. (author)An important problem that arises during the design of wind turbines is estimating extreme loads with sufficient accuracy. This is especially difficult during iterative design phases when computational resources are scarce. Over the years, many methods have been proposed to extrapolate extreme load distributions from relatively short time series...conference paper 2015

(author), Hulscher, S.J.M.H. (author), Lansen, A.J. (author)This paper explores an alternative method to determine extreme surge levels at the Dutch Coast. For this exploration, specific focus is on the extreme water level at Hoek van Holland, The Netherlands. The alternative method has been based on a joint probability model of the storm characteristics at the North Sea. The intent of this method is to...conference paper 2014

(author)Extreme rainfall is expected to occur more often in the future, as a result of climate change. To be able to react on this change, urban water managers need to accurately know vulnerable spots in the city, as well as the potential impact to society. Currently, detailed information about rainfall intensities in cities, and effects of intense...conference paper 2015

Bierbooms, W.A.A.M. (author)The probabilistic method commonly applied to arrive at the ultimate loading is as follows: for several different mean wind speeds load simulations are performed. For each mean wind speed a conditional distribution can be fitted to the load maxima for that particular wind speed. The overall distribution of the load response is obtained by a...conference paper 2010
