Uijterwaal, Paulien (author)The failure of composite laminates is most commonly evaluated through deterministic approaches. However, even though these traditional methods predict the failure well on average, they cannot take into account the inherent probabilistic aspect of failure mechanics. Thus, reliability methods allow for a better structural assessment and improve...master thesis 2021

Zondag, Youri (author)Since 2006, the Delft University of Technology has been working on the development of bacterial self-healing concrete (BSHC). The self-healing ability of this concrete is based on a biological mechanism, in which mineral producing bacteria are added to repair cracks autonomously. This not only improves the durability of concrete structures, but...master thesis 2021

Han, Han (author)Soil properties are spatially variable due to the natural deposition process. Because of this inherent spatial variability, a slope can actually fail along any potential slip surface. A single value of Factor of safety cannot account for this variation dominated the slope stability problem. Probabilistic analysis considering the spatial...master thesis 2021

Metz, I.C. (author), Ellerbroek, Joost (author), Mühlhausen, Thorsten (author), Kügler, Dirk (author), Hoekstra, J.M. (author)Bird strike prevention in civil aviation has traditionally focused on the airport perimeter. Since the risk of especially damaging bird strikes outside the airport boundaries is rising, this paper investigates the safety potential of operational bird strike prevention involving pilots and controllers. In such a concept, controllers would be...journal article 2021

Koosheh, Ali (author), Etemad-Shahidi, Amir (author), Cartwright, Nick (author), Tomlinson, Rodger (author), van Gent, M.R.A. (author)Conventionally, allowable mean overtopping discharge is used as a design criterion for coastal structures. The mean overtopping discharge needs to be limited to ensure structural stability as well as the safety of people, vehicles, and properties behind the structure. Nowadays, limits for the maximum individual overtopping volumes are also...review 2021

De Jaeger, Ina (author), Lago, Jesus (author), Saelens, Dirk (author)To assess the impact of implementing energy efficiency and renewable energy measures, urban building energy models are emerging. In these models, due to the lack of data, the natural variability of the existing building stock is often highly underestimated and uncertainty on the simulated energy use arises. Therefore, this work proposes a...journal article 2021

Maffei, C. (author), Lindenbergh, R.C. (author), Menenti, M. (author)Forest fires preparedness strategies require the assessment of spatial and temporal variability of fire danger. While several tools have been developed to predict fire occurrence and behaviour from weather data, it is acknowledged that fire danger models may benefit from direct assessment of live fuel condition, as allowed by Earth Observation...journal article 2021

Chockalingam, S. (author), Pieters, W. (author), Teixeira, André (author), van Gelder, P.H.A.J.M. (author)Water management infrastructures such as floodgates are critical and increasingly operated by Industrial Control Systems (ICS). These systems are becoming more connected to the internet, either directly or through the corporate networks. This makes them vulnerable to cyber-attacks. Abnormal behaviour in floodgates operated by ICS could be caused...journal article 2021

Ren, Jie (author), Wang, Yuan (author), Feng, Di (author), Gong, J. (author)Large volumes of carbon dioxide (CO<sub>2</sub>) captured from carbon emission source can be stored in deep saline aquifers as a mean of mitigating climate change. The deep saline aquifers are naturally heterogeneous at multiple scales. It is important to generate representative multiscale heterogeneous fields of various hydrogeologic...journal article 2021

Klerk, W.J. (author), Kanning, W. (author), Kok, M. (author), Bronsveld, J. (author), Wolfert, A.R.M. (author)Prioritisation of flood defence maintenance is typically based on visual inspection. However, literature shows that the Probability of Detection (PoD) of visual inspection can vary significantly. Here we investigate the PoD for visual inspections of flood defence structures, the consistency of damage classification, and the influence of...journal article 2021

Wen, P. (author), Lohlefink, C.G.K. (author), Rem, P.C. (author)Can random deposition create dense non-overlapping material feeding? The question is very fundamental for the research of particle packing, while the answer is of great importance for any industrial process that applies single object operation. To gain an insight into this issue, we studied the overlap problems of convex particles in the...journal article 2021

Since the 1950s, large-scale reclamation has been performed along the Shanghai coast, China, to fulfill the land demands of city expansion. We now show that the loss of tidal...journal article 2021

Li, Xinhong (author), Khan, Faisal (author), Yang, M. (author), Chen, C. (author), Chen, Guoming (author)Subsea gas release is an industrial hazard that can impose fire hazards on offshore facilities near the gas surfacing area. However, risk assessment of the fire caused by subsea gas release is challenged due to inadequate recognition of the knowledge of subsea gas release mechanism and resulting hazards. At present, minimal researches...journal article 2021

de Wit, J.J. (author), Pieters, W. (author), van Gelder, P.H.A.J.M. (author)Risk assessments in the (cyber) security domain are often, if not always, based on subjective expert judgement. For the first time, to the best of our knowledge, the individual preferences of professionals from the security domain are studied. In on online survey they are asked to mention, rate and rank their preferences when assessing a...conference paper 2021

Zhou, Ruoxi (author)This research focuses on the estimation the failure probability of Shanghai sea-dikes system, taking into account several failure mechanisms. This method follows fully probabilistic approach, in which all relevant parameters for the resistances and the hydraulic loads vary according to specific distributions.master thesis 2020

Goud, Thomas (author)When a breakwater is under heavy wave attack, the concrete armour units will occasionally move, causing a collision between two concrete armour units. This process is called rocking, and induces stresses in the concrete, that may lead to breakage of the concrete armour units. This MSc Thesis provides a probabilistic method to predict breakage of...master thesis 2020
