Individualizing mechanical ventilation treatment regimes remains a challenge in the intensive care unit (ICU). Reinforcement Learning (RL) offers the potential to improve patient outcomes and reduce mortality risk, by optimizing ventilation treatment regimes. We focus on the Offline RL setting, using Offline Policy Evaluation (OPE), specifically...

High-water levels in the Rhine-Meuse delta are going to rise in the upcoming decades due to climate change with the accompanied sea level rise and the increase of the frequency of extreme Rhine discharges. The flood prone areas not protected by flood defenses at the Island of Dordrecht are directly influenced by the increase of these high-water...

In the advanced semiconductor industry, modern electronic devices are expected to realize complex functions with minimized size, which requires an increase in the density of on-chip interconnects. To meet this demand, the dimension of interconnects is reduced and it requires the narrowing of metal interconnects to carry the increasing current...

Throughout the years the requirements of sheet pile walls have changed. Therefore reassessment of these structure's reliability is of importance. In this thesis, Bayesian updating is used for the reliability updating task. Updating processes require measurements of the structure under known conditions. Although for practical and economical...

In this thesis, an image-based method is proposed for solving the relative translation errors of 3D point clouds collected by Mobile Laser Scanning (MLS) techniques. The process of matching 3D point clouds is known as registration. Due to environment-depending limitations of the positioning component of MLS systems, when recording a certain...

Due to the increasing seaborne trade, shortage of officers, constant work of crew on machinery during voyage and the large contribution of human error to shipping accidents it is time for shipbuilding to take the next step in automation. Unmanned shipping is the way to move forward and since the engine room houses some of the most important...

It was unclear what level of reliability was provided by appliance of the Eurocode load models for fatigue due to train loads, meaning that it might be insufficient. Therefore, it was investigated what the provided reliability is, compared to what is should be. Within this report, the focus is solely on fatigue induced by bending moments on...

Some dike sections in the Netherlands failed to comply with the safety standards and one of the most promising countermeasures is the construction of retaining walls inside the dike. The Dutch design codes for dikes with retaining walls rely on Finite Element Analysis (FEM) in combination with partial safety factors. However, this can lead to...

Offshore wind energy has become a very hot topic in northwest Europe, both from an industrial as from an academic point of view. Research on transmission grids for offshore wind energy focuses predominately on radial grids and HVDC. This study broadens this general scope by taken mesh grids and HVAC as the starting point. With the use of load...

The worldwide demand for electricity, which is steadily increasing, leads to a continuous need for developing and extending the transmission networks. However, the installation of new overhead lines faces many challenges due to social, environmental and technical reasons. One solution that gains widespread public support is the installation of...

This thesis describes a method to find the best maintenance policy for a light rail rolling stock system based on reliability, availability, and maintenance cost. The objective of this maintenance policy is to maintain a minimum required level of system reliability at minimum maintenance cost and maximum availability. The maintenance policy...

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...

The DNV GL Health Index translates statistical, condition and utilization data of electrical power equipment into several asset representations that show technical asset health, including expected remaining lifetimes. These remaining lifetimes are used to determine the required action for the asset manager. In this research, a method was...

The traditional Dutch way to deal with piping for river levees is the implementation of piping berms. The disadvantage of such a measure is the inland space required, especially in urban areas. Relief wells, on the other hand, require less or no inland space and therefore represent an attractive solution as mitigation measure against piping. The...

Petabytes of data are processed daily by distributed applications built upon Hadoop and MongoDB. A significant fraction of these applications use cloud infrastructure to cope with this vast amount of data. Commercial clouds use virtualized environments, but most distributed applications are designed around the idea that they run on physical...

Reliability-based design is an approach currently gaining more popularity for geotechnical engineering. Neverthless, its implementation poses several challenges, one being the additional time (usually significant) in order to perform it. An important portion of this additional time comes from the need to perform many scenarios to compute the...

Introduction Floods are a threat to millions of people who live in lowlands like the Netherlands. Therefore the Dutch government has been given re-quirements for primary flood defence systems like dikes. The current condition of most of these dikes does not fulfill to these requirements based on flood risk analyses of RWS. The most logical step...

Reliability evaluation of power system substations is of significant importance when performing asset management. Most of the studies about substation reliability only focus on the substation connectivity. The reaction of protection system is fully neglected, which cannot be true in reality. Failures of the protection system failure or the...

Many of the assets managed by TenneT TSO have been installed in the sixties and seventies of the previous century. Consequently, 50% of their assets will reach their designed lifetime within ten years. Due to financial and technical restrictions not all the asset can be replaced based on their age. Hence, TenneT TSO developed a Health index tool...
