Comparing various measures to prevent covid-19 spread in offices through simulation modelling

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...

Why does the machine punish?: The effects of the use of machine learning in criminal sentencing on the application of the theories of punishment

In recent years, the practice of risk-assessment has started to utilize machine learning to take in larger data sets and improve prediction accuracy. Simultaneously, it has expanded into the sentencing stage of the criminal justice system. This paper analyzes the effect of these developments on the consideration of the theories of punishment...

Hidden Danger: Mapping consequences of underground water infrastructure failure to guide asset management

Continuous functioning of sewer systems and water distribution networks is crucial for liveability, public health and economic prosperity in urban areas. Progressive deterioration of these underground water infrastructures leads to an increased probability of failure. Maintenance is needed to ensure a desired level of functioning. For...

Collision risk assessment in coastal waters

The amount of international shipped cargo grows steadily, and seas are exploited for seabed mining and energy production more than ever. As a result, there is an increase in traffic density and decrease in free navigational space, potentially causing a higher incidence of dangerous navigation situations that may lead to ship collisions. This...

Assessing Cyber Security of Innovations for Climate Disaster Resilience: An Extension to the Test and Implementation Framework of the BRIGAID program

In the coming decades, more frequent and more extensive climate disasters such as coastal and river floods, droughts, extreme weather, and wildfires can be expected worldwide. Innovations will be required to face this grand challenge. The BRIGAID project developed a methodology consisting of a Test- and Implementation Framework and a set of...

Steering towards Stiffness: A preliminary analysis method for local deformations in a yacht structure caused by wave-induced loads

The superyacht industry faces an increasing trend of larger dimensions, more open spaces, larger hull openings and more exotic shapes. This puts more effort on the structural design and especially for superyacht longitudinal stiffness is important, since the luxurious interior and delicate systems installed in a superyachts are not allowed to...

In low- and middle income countries there is a need for safe and affordable high quality surgical equipment. Nowadays, electrosurgical units are part of the standard equipment in operation theatres worldwide, since electrosurgery comes with many advantages such as reduced blood loss. However, the technology of electrosurgery also carries several...

Designing a cyber risk assessment tool for small to medium enterprises

With the extensive use of the internet nowadays, companies are becoming more and more at risk from cyber-attacks. Especially SMEs are vulnerable, as they lack in cybersecurity. This is due to time, resource and knowledge constraints. In the literature no clear solutions can be found in order to help SMEs with their cybersecurity. To overcome...

Flood Risk Guayaquil: A critical analysis on inundations

Despite several researches about the hydrological and hydrodynamic system of the Guayas region, elementary insight of the total system was lacking. Therefore, the purpose of this study was to create a general overview regarding floods. Besides, basic solutions are proposed for preparing Guayaquil against floods which might be present in the...

Traceability in cyber risk assessment: A design science approach

Upscaling coastal flood risk assessment - Insight into the uncertainty of a continental-scale model

During the last years, flood risk assessments at continental and global scales are emerging as useful tools for risk hotspot identification, support for international policy-making and harmonization of strategies for climate change adaptation. The emergence of these models comes to cover the growing demand for integrated, large-scale risk...

Safety Assessment of Trans-boundary and Multi-modal Hazardous Materials Transportation: Concept Development: The LPG and LNG cases

Great amounts of hazardous materials are transported both inside and outside the countries, either in a single-mode or multi-modal way.

Improving the reliability of the compressed air supply to the blast furnaces at Tata Steel IJmuiden

The four blast furnace blowers at Tata Steel IJmuiden are essential for the operation of the blast furnaces. The blast blowers are steam turbines that drive large air compressors, with a power up to 37MW. In the last four years the blast blowers have suffered from a higher unplanned downtime than is acceptable for the company. This situation...

Dredge Plumes: Ecological risk assessment

Nowadays, the ecological effects of dredge plumes are usually managed based on the precautionary principle. Predictions of suspended sediment levels are made, which have to be compared to thresholds set by the responsible authority. Failing to comply may cause a project to be delayed and thus lead to additional costs. The precautionary principle...

Risk-based control of external salt water intrusion for the Rhine-Meuse Estuary

The fresh water supply will be more under pressure, due to the predicted effects of climate change in the Netherlands. More frequent salt water intrusion during the summer semester is caused by the joint occurrence of low river discharges and the expected sea level rise. The control of external salinity is necessary to guarantee a sufficient...

The influence of tropical operating conditions on the AC and impulse breakdown strength in gas insulated substation (GIS)

The ambient conditions could influence the breakdown strength of gas insulated substation. It is important to check if this influence will put the GIS into severe condition, especially in the presence of protrusion. A risk assessment is thus important for making decision if the GIS is safe to be operated.
