de Wit, J.J. (author)
Facing a (security) threat, what is the best thing to do? The overall research questions driving this study are about how security professionals assess, reason, and decide about security risks, and where their justification is founded on. The presented results are explorative, based on trying primarily to understand individual professional...

Boskeljon-Horst, L. (author)
In my nearly 24 years as an aviation psychologist in the Royal Netherlands Air Force (RNLAF), I have seen first-hand the dynamics and complexity of the daily work situations of pilots and crew. I have also seen an organisation trying to enhance safety, prevent negative incidents and advocate the importance of learning. And I have seen this same...

Burggraaf, J.M. (author)
Accidents at work come at a major cost including fatalities, disability and economic burden. The ideas around accident causation have changed over time from describing accidents as ‘acts of gods’ and as the fault of individual employees, to accidents being the result of an interaction between organizational, technical and human factors. Included...

Xue, J. (author)
Maritime shipping is essential to the global economy, while waterway transportation is recognized as a high-risk industry. Additionally, maritime accidents are frequently caused by human errors, and with the rapid improvement of science and technology, the improvement of autonomous ships has been technically feasible, which attracts the wide...

The homicide rate dropped globally in the last decades, while in the same period the percentage of unsolved homicide cases increased. At the same time technological developments have drastically changed our lives and little is known about how this influenced the process of decision-making within homicide investigations. Therefore, the aim of...

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...

Chen, P. (author)
Maritime transportation has been one of the major contributors to the global trade and economy. Accidents, however, have been continuously posing risks to individuals and societies in terms of loss of human life, economic and environmental consequences, etc. This thesis paid particular attention to the probabilistic risk analysis of ship...

Cayford, M.R. (author)
Surveillance of communications data is a contentious topic, typically centering on privacy vs. security questions. Central to this debate, but often overlooked, is the question of the effectiveness of the surveillance technology. This dissertation focuses on intelligence agencies in the U.S. and the U.K. and the evaluation of the effectiveness...

Huang, Y. (author)
Ship collision is a classical problem for maritime practitioners and researchers. Human error is a major cause of collision accidents, which motivates researchers to develop automation systems replacing navigators on board. However, before autonomous ships fully replace conventional ships, supporting the situational awareness of human operators...

Li, Y. (author)
Safety management systems (SMSs) have gained importance since the 1970s and changed focus from individual management activities to more systematic frameworks. The methods, techniques and tools used in them also became more and more sophisticated. However, from the perspectives of the researcher, company, auditor, government and (safety...

van Erp, H.R.N. (author)
We present here a Bayesian framework of risk perception. This framework encompasses plausibility judgments, decision making, and question asking. Plausibility judgments are modeled by way of Bayesian probability theory, decision making is modeled by way of a Bayesian decision theory, and relevancy judgments are modeled by way of a Bayesian...

Niu, L. (author)
There is an increasing concern about the interactions between phytoplankton and coastal ecosystems, especially on the negative effects from coastal eutrophication and phytoplankton blooms. As the key indicator of the coastal ecosystem, phytoplankton plays an important role in the whole impact-effect chain. Primary production by phytoplankton...

Wang, L. (author)
The modelling frameworks, which include greenhouse gas emission scenarios, climate models, downscaling methods and hydrological models, are generally used to assess climate change impacts on river floods. In this research, the uncertainty associated with each component of the modelling framework is analysed with particular reference to climate...

Verkade, J.S. (author)
Flood early warning systems provide a potentially highly effective flood risk reduction measure. The effectiveness of early warning, however, is affected by forecasting uncertainty: the impossibility of knowing, in advance, the exact future state of hydrological systems. Early warning systems benefit from estimation of predictive uncertainties,...

Nguyen, B.M. (author)
In coastal areas, Tropical Cyclones (TCs) are one of the greatest threats to humanity. Unfortunately, current risk reduction measures are not completely successful in lessening TC's consequences due to the remaining uncertainties in the estimates of key parameters, on which the designs of these measures rely. Because reliable observations of TCs...

Duricic, J. (author)
The majority of dams constructed in the world are dams that can be categorized as embankment dams. Throughout history we can point to many failures of dams, and embankment dams in particular. Nowadays it is clear that the goal to construct stable dams has not been achieved, even with advanced technologies and construction techniques available....

Bored piles are a type of deep foundations which have been and are being widely used in construction engineering such as high-rise buildings, bridges, jetties, and so on. Although bored piles have remarkable advantages over driven piles, the quality of bored piles is frequently affected by many causes of imperfection, which mainly come from the...

Ke, Q. (author)
In Shanghai, the main threat to the city’s safety is a typhoon induced storm surge in combination with a high astronomic tide in the Huangpu River. Historical flood events have shown that the weakness of the floodwall, with potential overtopping and breaching along the Huangpu River and its branches, has caused great economic damage and loss of...

This dissertation presents the applications of probabilistic-based frameworks in geotechnical and hydraulic engineering, for the assessment of the Red River dikes in Viet Nam. Dike along rivers often spread over the deltaic environment and its earthen structures are parts of a long civilian history, from hundreds to thousands of years....

Risk and reliability analysis is presently being performed in almost all fields of engineering depending upon the specific field and its particular area. Probabilistic risk analysis (PRA), also called quantitative risk analysis (QRA) is a central feature of hydraulic engineering structural design. Actually, probabilistic methods, which consider...
