Tunable Magnet Actuators: Hysteresis Modelling for Efficient and Accurate Magnetization State Tuning

In this thesis, the accuracy and efficiency of Magnetization State (MS) tuning in Tunable Magnet Actuators (TMAs) is investigated. TMAs are developed to improve thermal stability in quasi-static precision actuation applications. First, the operating principles of TMAs and limitations in previous work are discussed respectively. It is found that...

Improving and evaluating the methodology for calculating offshoring of emissions

This research aimed to improve the method to calculate offshoring of emissions to understand if developed countries were increasingly offshoring emissions towards developing countries. By offshoring, developed countries can achieve their climate goals without improving their carbon efficiencies. The widely-used method of the balance of emissions...

Design of a modular E-bike system

The popularity of shared E-bikes and sustainability is rising rapidly worldwide. The shared E-bike market likes to position itself as sustainable. Still, in reality, both faulty and decommissioned E-bikes get scrapped at enormous scales. This practice is far from sustainable. The problem with the existing shared bikes is that they are subject to...

Closure of the Gulf of Khambhat

This final thesis report describes the results of the feasibility analysis to the closure of the Gulf of Khambhat done by Erik Broos and Kees Wiersema, from Delft University of Technology. The study started with site visits to both Gujarat and La Rance where interviews were held to obtain insight in the desires of concerned parties as the...
