Yang, Z. (author)In many public places multiple sensing devices, such as cameras, are installed to help prevent unwanted situations such as aggression and violence. At the moment, the best solution to reach a safe environment requires human operators to monitor the camera images and take appropriate actions when necessary. In the wake of the terrorist attacks of...doctoral thesis 2009

Khakzad, N. (author), van Gelder, P.H.A.J.M. (author)In the context of natural-technological (natech) accidents, flood-induced damage of industrial plants have received relatively less attention mainly due to the scarcity of such accidents compared to those triggered by earthquakes, high winds, and lightnings. The large amount of oil spillage due to floods triggered by the Hurricanes Katrina and...journal article 2017

Khakzad, N. (author), van Gelder, P.H.A.J.M. (author)In the context of natural-technological (natech) accidents, flood-induced damage of chemical facilities have received relatively less attention mainly due to the scarcity of experimental or high resolution field observations. In the present study, we have introduced a methodology based on load-resistance relationships to assess the vulnerability...journal article 2017

Zarei, Esmaeil (author), Azadeh, Ali (author), Khakzad, N. (author), Mirzaei Aliabadi, Mostafa (author), Mohammadfam, Iraj (author)Pipelines are one of the most popular and effective ways of transporting hazardous materials, especially natural gas. However, the rapid development of gas pipelines and stations in urban areas has introduced a serious threat to public safety and assets. Although different methods have been developed for risk analysis of gas transportation...journal article 2017

Pearson, S.G. (author), Storlazzi, C.D. (author), van Dongeren, A. R. (author), Tissier, M.F.S. (author), Reniers, A.J.H.M. (author)Many low-elevation, coral reef-lined, tropical coasts are vulnerable to the effects of climate change, sea level rise, and wave-induced flooding. The considerable morphological diversity of these coasts and the variability of the hydrodynamic forcing that they are exposed to make predicting wave-induced flooding a challenge. A process-based...journal article 2017

Khakzad, N. (author), Landucci, Gabriele (author), Cozzani, Valerio (author), Reniers, G.L.L.M.E. (author), Pasman, HJ (author)The propagation of fire-induced domino effects in chemical plants largely depends on the primary fire scenario, on separation distances between the units, and on the presence of fire protection barriers. Passive and active safety barriers are widely employed to prevent or delay the initiation or propagation of domino effects. In the present...journal article 2018

Naderpour, Mohsen (author), Khakzad, N. (author)On February 2007, a massive fire in a propane de-asphalting unit in an oil refinery in Texas, USA happened due to liquid propane release from a cracked pipe in a control station injuring four people, damaging extensive equipment, causing significant business interruption, and resulting in more than $50 million losses. The accident was...journal article 2018

Witteveen, Annemieke (author), Nane, G.F. (author), Vliegen, Ingrid M.H. (author), Siesling, Sabine (author), IJzerman, Maarten J. (author)Purpose. For individualized follow-up, accurate prediction of locoregional recurrence (LRR) and second primary (SP) breast cancer risk is required. Current prediction models employ regression, but with large data sets, machine-learning techniques such as Bayesian Networks (BNs) may be better alternatives. In this study, logistic regression...journal article 2018

Jaeger, W.S. (author)This thesis investigates how selected multivariate probabilistic methods can be adapted for risk analysis and decision making in coastal and offshore environments. In particular, the thesis makes a contribution to decision support tools for risk reduction efforts in coastal environments and to statistical simulation methods for wave conditions....doctoral thesis 2018

Duvvuru Mohan, V.K. (author), Vardon, P.J. (author), Hicks, M.A. (author), van Gelder, P.H.A.J.M. (author)Bayesian networks are proposed as a tool to integrate reliability and influential variables relating to the slope stability of an idealized embankment. The site investigation (extent) and slope geometry, as well as the material properties and their spatial variability, are considered within a Bayesian network. The random finite element method ...conference paper 2019

Cincotta, Salvatore (author), Khakzad, N. (author), Cozzani, Valerio (author), Reniers, G.L.L.M.E. (author)Domino effects triggered by fire can cause extremely severe damages to the chemical and process plants. In the need of a more effective prevention of fire domino effects, the present study focuses on firefighting which has received less attention compared to passive and active fire protection systems. Considering both the vulnerability and...journal article 2019

Abrishami, S. (author), Khakzad, N. (author), van Gelder, P.H.A.J.M. (author), Hosseini, Seyed Mahmoud (author)Success Likelihood Index Model (SLIM) is one of the widely-used methods in human reliability assessment especially when data is insufficient. However, this method suffers from uncertainty as it heavily relies on expert judgment for determining the model parameters such as the rates and weights of the performance shaping factors. The present...conference paper 2019

Khakzad, N. (author)System safety and reliability assessment relies on historical data and experts opinion for estimating the required failure probabilities. When data comes from different sources, be it different databases or subject domain experts, the estimation of accurate probabilities would be very challenging, if not impossible, and subject to high epistemic...journal article 2019

de Ronde, Anouk (author), Kokshoorn, Bas (author), de Poot, Christianne J. (author), de Puit, M. (author)Fingermarks are highly relevant in criminal investigations for individualization purposes. In some cases, the question in court changes from ‘Who is the source of the fingermarks?’ to ‘How did the fingermark end up on the surface?’. In this paper, we explore the evaluation of fingermarks given activity level propositions by using Bayesian...journal article 2019

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

Wang, H. (author), Nunez, Alfredo (author), Liu, Zhigang (author), Zhang, Dongliang (author), Dollevoet, R.P.B.J. (author)The growing variety of data from condition monitoring of high-speed railways offer unprecedented opportunities to improve railway infrastructure maintenance. For condition monitoring of railway catenaries, this paper proposes a data-driven approach that uses a Bayesian network (BN) to integrate the inspection data from catenaries into a key...journal article 2020

Kammouh, O. (author), Gardoni, Paolo (author), Cimellaro, Gian Paolo (author)Resilience indicators are a convenient tool to assess the resilience of engineering systems. They are often used in preliminary designs or in the assessment of complex systems. This paper introduces a novel approach to assess the time-dependent resilience of engineering systems using resilience indicators. A Bayesian network (BN) approach is...journal article 2020

Chockalingam, S. (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...doctoral thesis 2020
