The effect of microstructure design on the oxidation and reduction behaviour of iron electrodes: Improving the performance of iron-air batteries

Pursuing sustainable and efficient energy storage technologies has led to advancements in iron-air batteries. Understanding the intricate relationship between the microstructural features of iron electrodes and their oxidation and reduction behaviour is crucial for optimizing battery performance and lifespan. This thesis aims to investigate the...

Creating seamless self-checkout areas in supermarkets using automatic customer exit control

This thesis is result of an assignment set up by Pan Oston. Pan Oston is a company who makes steel product like checkouts and kiosks for the retail market. A sizable part of Pan Oston’s revenue are checkouts and self-checkouts (SCOs). It is expected that in the future of retail these products are less relevant. This is why Pan Oston has...

Tunnel Stability Analysis and Geological Mapping using LiDAR and RGB Sensor Technologies in the Kristineberg Underground Mine

Measuring and analyzing the tunnel deformation through convergence measurements and cross-correlation with geological mapping is essential for understanding and controlling tunnel stability, worker safety and predicting failure zones. In order to achieve this, a new device, the so-called GroundProbe GML is tested and analyzed in this study....

Assessment of the reuse potential of existing concrete: Enhancing circularity in the Dutch building sector by harvesting structural elements from demolition projects

Awareness about our planet is more important than ever before. Thereby, the transition towards a Circular Economy (CE) aims to keep products in use and to design out waste. In the construction industry, one way of reducing the use of raw materials is by transforming waste residuals from demolition projects into resources to be reused. By...

''Speaking: Part I - Speaking architecture / Part II - Speaking architecture / Part III - Speaking through form: Three-part graduation project in Architecture and Science Communication

This series – “Speaking – is part of a graduation project for a double degree in Architecture and Science Communication at the Delft University of Technology. The overall aim of this project was to design a form language that can be used in complex problem-solving processes in the field of science communication. The graduation project consists...

Design Study of an Underreamer for Casing While Drilling Operations: Development, design analysis and concept selection

For present-day drilling operations in deep and challenging well sections, a technology called casing while drilling can be used. It involves isolating and ‘casing’ a formation while drilling, where the casing itself is used as the drill pipe, which is cemented in after a certain depth is reached. By doing this, the need for separate casing runs...

Speaking architecture: a semiotic study toward understanding visual communication in architecture

Architecture communicates. Through its appearance it can communicate a function, time or place, or some kind of ideal. However, architecture does not communicate with words like humans do: instead, it communicates through a four- dimensional, non-verbal language consisting of forms, spatial organisation and materialisation. The problem is,...

Reliability-based ultimate limit state design in finite element models

Assessing the dynamic stability of a floating tidal energy platform during ballast operations

A method is developed to assess the dynamic stability of a floating tidal energy platform during ballast operations. This method is applied to a tidal energy platform designed by Bluewater Energy Services B.V., showing the sensitivity of this platform’s dynamic stability during ballast operations to tidal current velocity, changes in lightship...
