Xu, Peng (author), Susilo, Willy (author), Wang, Wei (author), Chen, Tianyang (author), Wu, Qianhong (author), Liang, K. (author), Jin, Hai (author)Dynamic searchable symmetric encryption (DSSE) has been widely recognized as a promising technique to delegate update and search queries over an outsourced database to an untrusted server while guaranteeing the privacy of data. Many efforts on DSSE have been devoted to obtaining a good tradeoff between security and performance. However, it...journal article 2022

Lye, Adolphus (author), Cicirello, A. (author), Patelli, Edoardo (author)Bayesian inference is a popular approach towards parameter identification in engineering problems. Such technique would involve iterative sampling methods which are often robust. However, these sampling methods often require significant computational resources and also the tuning of a large number of parameters. This motivates the development...journal article 2022

Hejderup, J.I. (author), Gousios, G. (author)Developers are increasingly using services such as Dependabot to automate dependency updates. However, recent research has shown that developers perceive such services as unreliable, as they heavily rely on test coverage to detect conflicts in updates. To understand the prevalence of tests exercising dependencies, we calculate the test...journal article 2022

Jurisson, A. (author), Timmermans, Huub (author), Eussen, Bart (author), de Visser, C.C. (author), De Breuker, R. (author)A ground vibration test was conducted with a 1:3 scaled Diana 2 glider model where the modal parameters were estimated using the accelerometers, gyroscopes and strain gauges integrated in the test aircraft and validated using externally attached calibrated accelerometers and commercial software. These modal parameters were then used to update...conference paper 2022

(author), Arbous, M.S. (author), Reinders, M.J.T. (author)Background: Timely identification of deteriorating COVID-19 patients is needed to guide changes in clinical management and admission to intensive care units (ICUs). There is significant concern that widely used Early warning scores (EWSs) underestimate illness severity in COVID-19 patients and therefore, we developed an early warning model...journal article 2022

Chen, H. (author), Fu, S. (author), Liang, K. (author)Updatable encryption (UE) enables the cloud server to update the previously sourced encrypted data to a new key with only an update token received from the client. Two interesting works have been proposed to clarify the relationships among various UE security notions. Jiang (ASIACRYPT 2020) proved the equivalence of every security notion in...conference paper 2022

Steffner, Martin (author)This thesis project aims at exploring the challenges of sustainability within the segment of ski-helmets. It should lead to locating opportunities for transitioning them into the Circular Economy.<br/><br/>Ski-helmets are single-impact items, comprised of multiple different materials in inseparable product assemblies that prevent disassembly and...master thesis 2021

Bruins Slot, Hilco (author)The Netherlands is a country prone to flooding. Recent assessments led to the insight that protection levels of many flood defences should be increased. Integrating reinforcement measures is a difficult task as many dikes are situated in densely populated areas. Conventional reinforcement measures include berm construction or the implementation...master thesis 2021

Kentrop, Daniël (author)The construction of a dike improvement often causes a decrease in reliability during construction. Raising a dike may give rise to excess pore water pressures in the subsoil, resulting in a temporal strength decrease. Observing the survival of such a loading condition might provide information on the strength of a dike. Therefore, this research...master thesis 2021

Lye, Adolphus (author), Cicirello, A. (author), Patelli, Edoardo (author)This tutorial paper reviews the use of advanced Monte Carlo sampling methods in the context of Bayesian model updating for engineering applications. Markov Chain Monte Carlo, Transitional Markov Chain Monte Carlo, and Sequential Monte Carlo methods are introduced, applied to different case studies and finally their performance is compared....journal article 2021

van den Berg, Paulien (author), Scholten, D.J. (author), Schachter, Jonathan (author), Blok, K. (author)A dynamic and fast-changing environment brings challenges for generating long-term scenarios. Although the need to update scenarios for decision-making is recognized, a structured way for executing this process remains unclear. To configure a solution, we propose two concepts that need to be introduced: 1) that scenarios consist of a multi...journal article 2021

van der Krogt, M.G. (author), Schweckendiek, T. (author), Kok, M. (author)During construction of a dike, slope stability often reaches critical levels, due to the excess pore water pressures in the foundation. The loading condition during construction has similarities with the design conditions during flood loading. Not only in terms of the pore water pressures as the main driving force, but also in terms of...journal article 2021

Wouda, Frank J. (author), Jaspar, Stephan L.J.O. (author), Harlaar, J. (author), van Beijnum, Bert Jan F. (author), Veltink, Peter H. (author)Background: The foot progression angle is an important measure used to help patients reduce their knee adduction moment. Current measurement systems are either lab-bounded or do not function in all environments (e.g., magnetically distorted). This work proposes a novel approach to estimate foot progression angle using a single foot-worn...journal article 2021

Cenedese, Carlo (author), Belgioioso, Giuseppe (author), Grammatico, S. (author), Cao, Ming (author)In this paper, we present three distributed algorithms to solve a class of Generalized Nash Equilibrium (GNE) seeking problems in strongly monotone games. The first one (SD-GENO) is based on synchronous updates of the agents, while the second and the third (AD-GEED and AD-GENO) represent asynchronous solutions that are robust to communication...journal article 2021

Schouten, Onno (author)Quay walls are often designed with Finite Element models (FE models) to take into account the complex soil-structure interaction and highly non-linear soil behaviour. These are complex models that rely on many input parameters that have uncertainties. Nowadays, new quay walls are often equipped with sensors that collect information about the...master thesis 2020

Li, Ze (author)In SAR interferometry, the data acquired by satellite are large. The points in the dataset are usually expressed in spatial-temporal dimension in which many epochs may be included. Extra information including contextual values and data from other sources sometimes are important to be taken into account when analyzing the deformation based on the...student report 2020

Roscoe, K. (author), Hanea, Anca (author), Jongejan, R.B. (author), Vrouwenvelder, A.C.W.M. (author)In levee system reliability, the length effect is the term given to the phenomenon that the longer the levee, the higher the probability that it will have a weak spot and fail. Quantitatively, it is the ratio of the segment failure probability to the cross-sectional failure probability. The literature is lacking in methods to calculate the...review 2020

Kool, J.J. (author), Kanning, W. (author), Jommi, C. (author), Jonkman, Sebastiaan N. (author)Hindcasting of past levee failures enhances insights in the performance and vulnerability of levees. The scarcity of field evidence makes identifying the cause(s) of failure difficult. Under these circumstances, multiple scenarios and model choices are possible to characterise and to model the failure. This paper shows how probabilistic...journal article 2020

Büller, Jeroen (author)Throughout the years the requirements of sheet pile walls have changed. Therefore reassessment of these structure's reliability is of importance. In this thesis, Bayesian updating is used for the reliability updating task. Updating processes require measurements of the structure under known conditions. Although for practical and economical...master thesis 2019
