Partial discharge (PD) measurements in gasinsulated substations (GIS) are tested according to the standard IEC 60270. This “conventional” PD test method applies to electrically small devices. The equipment size increases the resonance, and attenuation, contributing to the total uncertainty. Additionally, when an ultra-high frequency (UHF) sensor...

Universities open their doors to society, inviting the complexity of the world to enter engineering education through challenge-based courses. While working on complex issues, engineering students learn to deal with different kinds of uncertainty: uncertainty about the dynamics of a real-world challenge, the knowledge gaps in the problem, or...

Satellite-based Earth Observation systems archived a variety of vegetation products during the last 50 years, which can reveal regional to global ecosystem dynamics across diverse spatiotemporal scales. The anomaly metrics such as Vegetation Condition Index (VCI) defined by comparing the current vegetation growth condition to historical...

The challenges we collectively face, such as climate change, are characterized by more complexity, interdependence, and dynamism than is common for educational practice. This presents a challenge for (university) education. These sustainability transition challenges are often described as wicked or VUCA (Volatile, Uncertain, Complex, and...

The increasing capacity of offshore wind energy around the world brings challenges in Operation and Maintenance (O&M) management. Over the past years, many studies have focused on developing sound maintenance strategies in order to minimize maintenance cost or maximize availability. One of the promising maintenance strategies is...

Unexpected disruptions occur frequently in railway systems, during which many train services cannot run as scheduled. This paper deals with timetable rescheduling during such disruptions, particularly in the case where all tracks between two stations are blocked for a few hours. In practice, the disruption length is uncertain, and a disruption...

Bayesian networks are proposed as a tool to integrate reliability and influential variables relating to the slope stability of an idealized embankment. The site investigation (extent) and slope geometry, as well as the material properties and their spatial variability, are considered within a Bayesian network. The random finite element method ...

This paper presents a study carried out to first assess the impact of the Panama Canal expansion (PCE) on selected Caribbean ports, and thereafter, to examine how the ports can adapt in order to seize new opportunities created by the expansion. An applied case of long-term dynamic planning and flexibility in engineering design is presented for a...

In the present turbulent environment, adaptability and robustness belong under the overarching definition of sustainability. Sustainable infrastructures should not only achieve economic, environmental, and social objectives, but should be robust and adaptable under uncertainty. This paper examines the current guidelines for port development and...

In the present time of sea-level rise and climate change a global shift has occurred toward sandy coastal protection measures and Building with Nature. These type of protection measures impose extra uncertainty on the instantaneous state of the coastal system over time for which present deterministic forecasting techniques are not capable of...

Design-led innovation (DLI) is a framework with particular focus on developing design capability. Implementation of DLI has been observed to positively influence firm innovation performance. As the framework is of relative infancy, there is opportunity to learn from and integrate methods and practice from other fields to strengthen the...

Rabies is a viral fatal disease transmitted to humans mainly from dogs. Human deaths due to rabies have been increasing in recent years, especially in Africa and Asia where socioeconomic factors play an important role in the revival of the epidemic. In the current situation, it is unknown how the epidemic will evolve and which policies can...

Bio-methane is a renewable gas option that can be injected to the natural gas grids to increase the sustainability of the energy system and to deal with natural gas supply problems. However, being based on several factors such as resource availability, competition between bio-methane and electricity sectors for biogas and biomass supply, demand,...

The US’ shale gas revolution, a spectacular increase in natural gas extraction from previously unconventional sources, has led to considerable lower gas prices in North America. This study focusses on consequences of the shale gas revolution on state stability of traditional oil and gas exporting countries in the vicinity of the EU. For this...

The copper case is often used as an example in resource depletion studies. Despite these studies, several profound uncertainties remain in the system. One of these uncertainties is the distribution of copper grades in the lithosphere. The Skinner thesis promotes the idea that copper grades may be distributed with a bimodal distribution instead...

Even without uncertainty about the model structure or parameters, the output of a hydrological model run still contains several sources of uncertainty. These are: measurement errors affecting the input, the transition from continuous time and space to discrete time and space, which causes loss of information about the input, discretization of...

We design new algorithms for the problem of allocating uncertain, flexible, and multi-unit demand online given uncertain supply, in order to maximise social welfare. The algorithms can be seen as extensions of the expectation and consensus algorithms from the domain of online scheduling. The problem is especially relevant to the future smart...

Import dependency and the extent of renewable gas production are two outcomes of interest concerning the future of gas supply in the Netherlands. Due to the complexity of internal mechanisms and uncertainties associated with the natural gas production, the production of renewable gases, and the demand for gas, the future of these two outcomes of...

To guarantee a safe flood defence in a changing environment, the adaptation to climate change needs to be considered in the design of river dikes. However, the large uncertainty in the projections of future climate leads to varied estimations of future flood probability. How to cope with the uncertainties in future flood probability under...
