Increasing fuel prices and the increasing environmental awareness has led to an increasing importance of truck aerodynamics in the automotive transport sector. At highway speeds the aerodynamic drag of a truck leads to 40% of the total fuel consumption, making aerodynamic improvements an important field of possible fuel consumption reduction....

The apparel industry is the second most polluting industry in the world, but the products they produce are used highly inefficiently. For every bag that is used on a daily basis, three bags are stored away in a closet. The Insider system is a product-service system that provides its users with the right bag on-demand. By making any bag you might...

Understanding the process of human motion perception is essential for optimizing the motion cueing algorithms (MCAs) used by motion simulators. Previous research has shown that different motion cueing error types can be distinguished, at least some of which are rated differently by humans for equal error magnitude. Optimizing a motion simulation...

Cutter suction dredgers are a type of hydraulic dredgers often used in areas with hard soil where other types of dredging vessels would be ineffective. As a result of the wide range of type of soil that is being cut a lot of variation is seen in the power demand on the cutter suction dredger's diesel-electric power generation system....

All ships rely on many on board systems to reliably complete their missions (e.g. transporting containers, laying pipes or protecting the seas). However, for many of these ships, the detailed design of these systems is put off until the later stages of the design. For most ships, this will create no problems. However, for those complex vessels...

Current literature on the usage of the experience curve in a societal cost-benefit analysis is lacking. It is unclear how the experience curve should be used in a societal cost benefit analysis and how large the effect or added value is. This thesis uses a case study to analyses effects of the experience curve on a societal cost benefit analysis...

The heat pipe assisted annealing project is a project in which Tata Steel, TU Delft and Drever International work together to develop a continuous annealing line with heat pipes. In an annealing line cold rolled steel is heated to 973 K and cooled down again to change the properties of the steel. In the heat pipe assisted annealing project the...

Epoxy resins are increasingly used in critical structural components with widespread applications in the transportation, construction and energy industries. The wind energy sector is one of the fastest growing commercial markets for epoxy resins, meaning that the structural behaviour of epoxy resins is becoming a key area of research, especially...

A hydrogen fuel cell scooter was tested for the first time to alternatively drive, power electric appliances (Vehicle-to-Load, V2L) and power the grid (Vehicle-to-Grid, V2G). Performance of the scooter is known to rely mainly on the fuel cell stack, and fuel cell degradation depends on the operating conditions. This study aimed to provide...

In most current dike assessments only the stationary water levels are investigated in the assessment of the stability of the inner slope, while there are differences for all kind of dikes between the stationary and transient pore water pressures and therefore in the stability. This results in a conservative probability of failure, while...

With the advent of high-bandwidth non-volatile storage devices, the classical assumption that database analytics applications are bottlenecked by CPUs having to wait for slow I/O devices is being flipped around. Instead, CPUs are no longer able to decompress and deserialize the data stored in storage-focused file formats fast enough to keep up...

In the recent years the satellite industry has progressed on the subject of optical communication for use in space. With recorded speeds over 5 Gb/s it has shown to be an alternative for radio communication. In the CubeSat market this technology is new, underdeveloped, and could lead to new missions that were not possible before. As such, TNO...

Participant feedback in previous research indicates a need for pilot training to handle non-routine situations with automation surprises. Therefore, we tested the effectiveness of using active problem solving during training on subsequent performance while dealing with automation surprises. We simulated a glass cockpit of a general aviation...

When building a convolutional neural network, many design choices have to be made. In the case of Deepfake detection, there is no readily implementable recipe that guides these choices. This research aims to work towards understanding the effects of design choices in the case of Deepfake detection, using the Python library Keras and publicly...

The emergence of connected and automated vehicles (CAVs) could have a significant impact on traffic efficiency and safety. The effects of CAVs in regular highway traffic are relatively well represented in scientific research. How these effects change in exceptional situations, such as work zones, and how the infrastructure can influence these...

The Oxygen Evolution Reaction (OER) is usually the go-to reaction for water-based electrolysis processes. However, this reaction can impede the performance and large-scale implementation of such processes due to its sluggish kinetics and the lack of value of its product stream. In order to boost the feasibility of electrochemical processes,...

The Dutch Railways (NS) is the Dutch national passenger railway operator. They own rolling stock that has to be maintained regularly. One of the maintenance facilities executing regular maintenance on regional trains is the maintenance department (OB) in Leidschendam. The aim of this project is to develop a framework for optimizing the...

“In which way can the design of the residential environment contribute to the social self-reliance of young people with a mild intellectual disability?” We are facing a huge challenge in the Netherlands: we have to build up to ‘1 Million Homes’ by 2030. But such a huge assignment raises the question if those new dwellings will be inclusive...
