Li, M. (author), Mou, Junmin (author), Chen, Pengfei (author), Chen, Linying (author), van Gelder, P.H.A.J.M. (author)Regional risk analysis and management of maritime accidents is one of the fundamental tasks for maritime safety management. With the heavy and complicated maritime traffic in the ports and waterways, accidents, especially ship collision accidents, have been continuously posing threats to the maritime transportation system. To achieve effective...journal article 2023

van der Werf, J.A. (author), Kapelan, Z. (author), Langeveld, J.G. (author)Urban Drainage Systems can cause ecological and public health issues by releasing untreated contaminated water into the environment. Real-time control (RTC), augmented with rainfall nowcast, can effectively reduce these pollution loads. This research aims to identify key dynamics in the nowcast accuracies and relate those to the performance...journal article 2023

Visser, Florida (author)This research explores the frequent urban flooding problems typically experienced in South-East Asian cities. Heavy rainfall during the monsoon period in combination with rapid urbanisation in the past decades causes an increasing amount of inundation events in the case study area Hanoi. The damage caused by these floods results in major...master thesis 2022

Deijkers, Emma (author)COVID-19 has had a great impact worldwide. One of its many effects was that offices had to be closed, which negatively affects the economy and people’s mental health. It is important that a safe way to keep offices open is found. Non-Pharmaceutical Interventions (NPIs) are an important way to do this. However, to pick the right NPIs for one’s...master thesis 2022

Claassen, Carlijn (author)The combination of the high number and the consequences of falls in older adults led to the development of fall risk assessments; non-sensor-based and sensor-based. Multiple studies used ML for older adults' fall risk prediction using raw IMU data. This study's objective was to develop a DL algorithm that predicts the fall risk of people living...master thesis 2022

Smit, Michiel (author)Coastal and offshore infrastructure must be designed to withstand extreme wave-induced loading conditions. Extreme Value Analysis (EVA) is often employed to infer probabilistic distributions that provide information about extreme design conditions. In traditional practices, EVA is performed under the assumption of stationarity. This means that...master thesis 2022

Klunder, Tom (author)Quantum computing presents a threat to the current cryptographic standards in place, supporting our digital scoiety. As our lives are increasingly dependent on electronic transactions, our society becomes increasingly vulnerable to distortions of digital trust. By taking a design science research approach, this thesis designs a risk assessment...master thesis 2022

Peng, Z. (author), Pineda Rojas, A.L. (author), Kropff, E. (author), Bahnfleth, W. (author), Buonanno, G. (author), Dancer, S.J. (author), Kurnitski, J. (author), Li, Y. (author), Boerstra, A.C. (author), Jimenez, J.L. (author)Some infectious diseases, including COVID-19, can undergo airborne transmission. This may happen at close proximity, but as time indoors increases, infections can occur in shared room air despite distancing. We propose two indicators of infection risk for this situation, that is, relative risk parameter (Hr) and risk parameter (H). They combine...journal article 2022

Chen, Tzu Yin Kasha (author), Hung, Chi Yao (author), Chiang, Y.-C. (author), Hsieh, Meng Long (author), Capart, Hervé (author)In some steep valleys, flood-induced changes in river bed elevation pose significantly greater risks to infrastructure than floodwaters alone. Over the short term, the river may aggrade or degrade by several meters during a single flood. Whereas floodwaters recede after each event, moreover, riverbed changes add up over successive floods. To...journal article 2022

He, X. (author), Jiang, C. (author), Li, L. (author), Blom, H.A.P. (author)UAS-based commercial services such as urban parcel delivery are expected to grow in the upcoming years and may lead to a large volume of UAS operations in urban areas. These flights may pose safety risks to persons and property on the ground, which are referred to as third-party risks. Path-planning methods have been developed to generate a...journal article 2022

Decisions regarding the reopening of businesses should account for infection risks. Objective: This paper describes a novel model for COVID-19 infection risks and policy evaluations. Methods: The model combines the best principles of the agent-based, microexposure, and...journal article 2022

Bianchi, S. (author), Ciurlanti, J. (author), Overend, M. (author), Pampanin, Stefano (author)Structural safety and environmental sustainability are major factors in investment decisions for building systems, but are rarely considered simultaneously. Recent research efforts have redressed this by developing assessment methodologies and technical solutions for integrated energy efficiency and seismic performance. These studies are...journal article 2022

Rikkert, S.J.H. (author), Kok, M. (author), Lendering, K.T. (author), Jongejan, R.B. (author)Flood prone areas are often protected against flooding by an extensive network of flood defenses. To ensure their structural integrity, these flood defenses are periodically assessed. Many levees have been functioning well for decades, and have survived several relatively high hydraulic loads within their lifetime. However, information on...journal article 2022

Seis, W.A.A. (author), Rouault, Pascale (author), Miehe, Ulf (author), ten Veldhuis, Marie-claire (author), Medema, G.J. (author)Norovirus infections are among the major causes of acute gastroenteritis worldwide. In Germany, norovirus infections are the most frequently reported cause of gastroenteritis, although only laboratory confirmed cases are officially counted. The high infectivity and environmental persistence of norovirus, makes the virus a relevant pathogen...journal article 2022
