Arango, E.A. (author), Santamaria, Monica (author), Nogal Macho, M. (author), Sousa, Helder S. (author), Matos, Jose C. (author)Assessing flood risks on road infrastructures is critical for the definition of mitigation strategies and adaptation processes. Some efforts have been made to conduct a regional flood risk assessment to support the decision-making process of exposed areas. However, these approaches focus on the physical damage of civil infrastructures without...conference paper 2022

Semertzis, I. (author), Subramaniam Rajkumar, Vetrivel (author), Stefanov, Alexandru (author), Fransen, Frank (author), Palensky, P. (author)Over the past decade, the number of cyber attack incidents targeting critical infrastructures such as the electrical power system has increased. To assess the risk of cyber attacks on the cyber-physical system, a holistic approach is needed that considers both system layers. However, the existing risk assessment methods are either qualitative in...conference paper 2022

Kim, I.-C. (author), Kaihatu, J.M. (author)As surface waves propagate from deep water toward shallow coastal areas, their ensuing transformation is due to the influence of bathymetry and several important phenomena, such as refraction, shoaling ,and nonlinear effects. Nonlinear wave models based on the classical Boussinesq equation(Peregrine, 1967)have evidenced good performance in...conference paper 2021

Ferreira, A.M. (author), Garzon, J.L. (author), Ferreira, Ó. (author), Fortes, C.J.E.M. (author), Reis, M.T. (author)Low-lying coastal areas can be very vulnerable to extreme storms inducing overtopping and flood events with severe socioeconomic consequences. Also, the associated risk is expected to increase due to sea level rise and coastal population growth. Under this threat, early warning systems (EWS) are a crucial tool for coastal planning and management...conference paper 2021

Ishikawa, T. (author), Shimada, R. (author), Sawagashira, R. (author), Komine, T. (author)There are from 2,000 to 3,000 rescues including those of unconscious people every year on the beaches of Japan, as shown in Fig. 1. The occurrence of drowning accidents is mainly caused by the rip current (Ishikawa et al., 2014), it accounts for 48 % of drowning accidents, as shown in Fig. 2. Also, in Australia, the United States and the United...conference paper 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

van den Berg, Jan (author)For most people, cybersecurity is a hard to grasp notion. Traditionally, cybersecurity has been considered as a technical challenge and still many specialists view it equivalent with information security, with the notions of confidentiality, integrity and availability as starting points of thinking. And although others searched for a broader...conference paper 2019

Janssen, S.A.M. (author)We investigate the use of an Agent-based framework to identify and quantify the relationship between security and efficiency within airport terminals. In this framework, we define a novel Security Risk Assessment methodology that explicitly models attacker and defender behavior in a security scenario. It produces a security risk vector,...conference paper 2017

Mullakkal-Babu, F.A. (author), Wang, M. (author), Farah, H. (author), van Arem, B. (author), Happee, R. (author)Safety measurement and analysis have been a challenging and well-researched topic in transportation. Conventionally, surrogate safety measures have been used as safety indicators in simulation models for safety assessment, in control formulations for driver assistance systems, and in data analysis of naturalistic driving studies. However,...conference paper 2017

Blom, H.A.P. (author), Bakker, GJ (author)Effective collaboration between planning controller, tactical controller and pilots in handling various uncertainties and hazards is the result of decades of evolutionary development. The forthcoming paradigm shift to Trajectory Based Operations (TBO) requires a similarly effective collaboration between the TBO layer and a tactical layer....conference paper 2017

Labunets, K. (author), Massacci, Fabio (author), Tedeschi, Alessandra (author)Security risk assessment methods in industry mostly use a tabular notation to represent the assessment results whilst academic works advocate graphical methods. Experiments with MSc students showed that the tabular notation is better than an iconic graphical notation for the comprehension of security risks. [Aim] We investigate whether the...conference paper 2017

Martinović, Karlo (author), Gavin, Kenneth (author), Reale, Cormac (author)Landslides cause hundreds of deaths and billions euros of damage to infrastructure and the environment each year. In order to predict the locations most susceptible to landslides, the field of landslide hazard assessment has gone through a massive development in the last twenty years by introducing a wealth of statistical and geotechnical...conference paper 2016

Sujitha, S. (author), Datta, S. (author), Babu, G.L.S. (author)In this paper, a radiological model for the risk assessment is developed for the near surface disposal facilities of Cesium, Strontium and Cobalt. In addition to the time-dependent annual release rate and dose rate of the radionuclides, the risk to the critical individual is also estimated. The results show that the highest value of annual dose...conference paper 2015

Halter, W.R. (author)Many governments want to realize wind power, because it is a technology that promotes sustainable energy. That is why there is need for locations for wind farms (groups of wind turbines). Dikes are good locations for wind farms, because of favourable wind conditions, the absence of cultivation and the presence of road infrastructure. However,...conference paper 2015

Zhang, Y.-J. (author), Feng, X.-T. (author), Jiang, Q. (author)The epistemic uncertainty and aleatory uncertainty caused by the geology condition and construction method make the surrounding rock stability evaluation of underground cavern group difficult. The first may be reduced with more field investigation, tests or monitoring, but the later can not be avoided completely. So the risk analysis method can...conference paper 2015

Chen, H.X. (author), Zhang, L.M. (author)Shallow slope failures are one of the most frequent geological hazards in mountainous areas, which pose great danger to people and properties in affected areas. This paper presents a cell-based platform for quantitative risk assessment for shallow slope failures at a regional scale. There are five components in this platform; namely, a digital...conference paper 2015

Meng, J. (author), Huang, J. (author), Sloan, S.W. (author)Slope instability and landslides can be catastrophic events often leading to loss of life and property. To assess the risks of slope failures, it is often desired that the dynamic process of slope failure can be simulated. This paper proposes a Granular Contact Dynamics (GCD) approach based on variational principles and implicit time integration...conference paper 2015
