Looman, Menno (author)Traditionally, Event-Triggered Control (ETC) methods are sample-and-hold control schemes that implement a triggering condition in order to reduce the number of control updates. Given a decay rate of the Lyapunov function, they focus on minimizing the (average) Inter-Sample Time (IST). In this thesis, we focused on the scheduling of Periodic...master thesis 2023

Pantelidis, Giannis (author)Circular Economy (CE) is a new economic development paradigm that is proposed as a counterweight to the traditional “take, make, use and dispose” model, known as Linear Economy (LE). To cope with the increasingly environmental impact of construction, a transition towards CE can be the solution. To that direction, several circular initiatives in...master thesis 2023

Guillou, Nicolas (author), Lavidas, G. (author), Kamranzad, Bahareh (author)Refined numerical wave energy resource assessments are required to reduce uncertainties in the evaluation of available power and energy production. However, to restrict the computational cost, a great part of wave hindcast simulations cover a limited time range (below ten years) or rely on coarse spatial resolutions while routinely ignoring tide...journal article 2023
