Brus, Daniël (author)In many fields we are interested in inference for a complex stochastic process given limited observations regarding its state over time. This thesis therefore introduces an expectation propagation approach to backward filtering forward guiding for high-dimensional finite-state space models. The backward filtering forward guiding method is first...master thesis 2023

An, Xu (author), Yin, Zhiming (author), Tong, Qi (author), Fang, Yiping (author), Yang, M. (author), Yang, Qiaoqiao (author), Meng, Huixing (author)The interactions of external disruptions and technical-human-organizational factors in emergency operations are usually observed. Resilience assessment of emergency systems can improve emergency response capability and system functional recovery. The increasing complexity and coupling of factors in emergency response systems need to be...journal article 2023

Morato, P. G. (author), Andriotis, C. (author), Papakonstantinou, K. G. (author), Rigo, P. (author)In the context of modern engineering, environmental, and societal concerns, there is an increasing demand for methods able to identify rational management strategies for civil engineering systems, minimizing structural failure risks while optimally planning inspection and maintenance (I&M) processes. Most available methods simplify the I...journal article 2023

Huang, Y. (author), Qin, Guojin (author), Yang, M. (author)RBI, referring to a risk-based approach to inspection planning, is an established pipeline integrity management method. Both corrosion and dents are the primary threats to pipeline integrity. However, they are often treated separately in RBI without considering their interactions. This coupling may lead to a synergic effect on integrity...journal article 2023

Klerk, W.J. (author), van Bergeijk, Vera (author), Kanning, W. (author), Wolfert, A.R.M. (author), Kok, M. (author)The condition of flood defence revetments is influenced by many different degradation processes such as animal burrowing, rutting and growth of weeds. Many of these processes are shock-based rather than progressive continuous. As shocks can cause a drop in performance, this means that the condition of a revetment can suddenly decrease,...journal article 2023

Heng, J. (author), Zheng, Kaifeng (author), Feng, Xiaoyang (author), Veljkovic, M. (author), Zhou, Zhixiang (author)This study integrates the fatigue test and numerical prediction to derive a comprehensive probability-stress-life (P-S-N) curve for rib-to-deck (RD) welded joints in orthotropic steel decks. Fatigue tests of RD joints are conducted to measure fatigue strength and crack growth data. Based on the test, a probabilistic fatigue crack growth (PFCG...journal article 2022

Svenningsson, P.O. (author), Fioranelli, F. (author), Yarovoy, Alexander (author), Martone, Anthony F. (author)In this article, a statistical model of human motion as observed by a network of radar sensors is presented where knowledge on the position and heading of the target provides information on the observation conditions of each sensor node. Sequences of motions are estimated from measurements of instantaneous Doppler frequency, which captures...journal article 2022

de Kok, Tim (author)Implementation of nature-based solutions (NBS) in flood defenses is hindered by a lack of probabilistic tools and design guidelines that can be used to assess spatial and temporal variability in these biophysical systems. It is well established that nature-based elements, such as vegetation, attenuate waves, capture sediment, strengthen the...master thesis 2021

Zinetullina, Altyngul (author), Yang, M. (author), Khakzad, Nima (author), Golman, Boris (author), Li, Xinhong (author)The emergent hazards of chemical process systems cannot be wholly identified and are highly uncertain due to the complicated technical-human-organizational interactions. Under uncertain and unpredictable circumstances, resilience becomes an essential property of a chemical process system that helps it better adapt to disruptions and restore...journal article 2021

Zhu, Jingyu (author), Chen, Guoming (author), Khan, Faisal (author), Yang, M. (author), Li, Xinhong (author), Meng, Xiangkun (author), He, Rui (author)Managed Pressure Drilling (MPD) system is widely used in the deepwater drilling operation. Reliability assessment plays a critical role in the MPD system in the management of drilling operation risk and the prevention of blowouts. However, the reliability assessment of the MPD system is challenged due to its sequential operations and multiple...journal article 2021

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

Radityo Andjaringrat Adhi, Theo (author)Maturity model has proven to be helpful for an organization to identify its current capability, strength, and weaknesses through maturity levels. These levels are used to rank the various dimension or process of an organization. However, maturity levels only describe a general description of organization capability. The effect of different...master thesis 2019

Radityo Andjaringrat Adhi, Theo (author)Maturity model is widely known as an assessment tool to understand an organization management capabilities and identifying potential improvement. The model demonstrates informative results towards the organization management maturity but hard to acknowledge the influence of potential improvement towards the organization’s asset performance....master thesis 2019

Kooij, J.F.P. (author), Flohr, F.B. (author), Pool, E.A.I. (author), Gavrila, D. (author)Anticipating future situations from streaming sensor data is a key perception challenge for mobile robotics and automated vehicles. We address the problem of predicting the path of objects with multiple dynamic modes. The dynamics of such targets can be described by a Switching Linear Dynamical System (SLDS). However, predictions from this...journal article 2019

Li, Zongkun (author), Wang, Te (author), Ge, W. (author), Wei, Dong (author), Li, Hanyu (author)Despite the fact that the Bayesian network has great advantages in logical reasoning and calculation compared with the other traditional risk analysis methods, there are still obvious shortcomings in the study of dynamic risk. The risk factors of the earth-rock dam breach are complex, which vary with time during the operation period. Static...journal article 2019

Khakzad, N. (author), Landucci, G. (author), Reniers, G.L.L.M.E. (author)The propagation of fire in chemical plants – also known as fire domino effects - largely depends on the performance of add-on passive and active protection systems such as sprinkler systems, water deluge systems, emergency shut down and emergency blow down systems, fireproofing, and emergency response. Although such safety barriers are widely...journal article 2017

Van de Lisdonk, R.H.M. (author)New ideas to improve automatic speech recognition have been proposed that make use of context user information such as gender, age and dialect. To incorporate this information into a speech recognition system a new framework is being developed at the MMI department of the EWI faculty at the Delft University of Technology. This toolkit is called...master thesis 2009

Wiggers, P. (author)Speech is at the core of human communication. Speaking and listing comes so natural to us that we do not have to think about it at all. The underlying cognitive processes are very rapid and almost completely subconscious. It is hard, if not impossible not to understand speech. For computers on the other hand, recognising speech is a daunting...doctoral thesis 2008
