Designing AI projects using a reactive digital canvas

Supporting designers working with AI is important, yet the tools they have at their disposal are in many ways not satisfactory. The aim of this project was to design a digital canvas tool which lets designers explore AI and ML, adopt the affordances that AI and ML as a design material give, and which can be used to map out and design integrated...

The Lagrangian Mimetic Spectral Element Method: Solving (non-)Linear Advection Problems with a Mimetic Method

Advection is at the heart of fluid dynamics and is responsible for many interesting phenomena. Unfortunately, it is also the source of the non-linearity of fluid dynamics. As such, its numerical treatment is challenging and often suboptimal. One way to more effectively deal with advection is by using a Lagrangian formulation instead of the...

Analyses of the Oil Management in High-Temperature Heat Pumps and Modelling of the Oil-Refrigerant Separation

Due to financial and environmental benefits, the interest in high-temperature heat pumps, producing heat sinks above 100 °C, is rising. Research is intensifying, and technology is developing fast. However, of all the components of the heat pump cycle, the oil management system seems to be the least investigated, even though 12% of the faults in...

Bug Detection in Distributed Systems with Platform-independent Fault Injection: A Case Study at Adyen

Fault injection has been a long-standing technique for testing software. Injecting faults into a system, either in production or development environments, offers unique opportunities to discover bugs that are difficult to reproduce using conventional testing methods. However, it is widely considered to have a high implementation threshold. Due...

Dielectric Metasurface Designs for Surface Enhanced Raman Scattering with Large Distances between Nanoparticles

In this thesis new dielectric metasurfaces in immersion were explored with a periodic distribution of unit cells with multiple silicon cylinder structures on a reflective gold slab with a fused quartz spacer in between. These new metasurfaces were designed with 60 nm and 130 nm gaps in order to improve manufacturability and enable larger...

Possible integrated coastal interventions in Playa Unión and Puerto Rawson: An area prone to coastal erosion

Playa Unión and Puerto Rawson are facing severe coastal erosion and increasingly the negative effects. Since the first half of the 20th century there have been signs of erosion, but also of sedimentation. However, the coastline in the project area is retreating over the years. The situation has recently been declared an emergency. Furthermore,...

Enhancing Greenhouse Gas Emission Performance of Offshore Installation Vessels through Swappable Energy Containers

This master’s thesis explores an alternative approach to enhance the emission performance and energy efficiency of offshore installation vessels without expensive retrofits. The concept involves employing swappable energy containers, currently used for inland cargo and tug vessels, for offshore installation vessels. These containers are filled...

Product-ProtoNet: A simple architecture for classifying supermarket products, using just a few example images

Airlab, a collaboration between TU Delft and Ahold Delhaize, is developing Albert, a robot tailored to work in a complex supermarket environment. Key to Albert is a product detection and classification module that tells it what products to grasp and where they are located in a shelf. Albert’s existing YOLO‑based product detector a significant...
