De oehoe is in Nederland sinds de jaren ’80 sterk in aantal gegroeid: van 7 broedparen naar 103 territoria in 2024. Aanvankelijk was de soort een habitat­specialist die uitsluitend in steengroeves broedde, maar tegenwoordig gedraagt zij zich als bosgeneralist. Dit onderzoek analyseert de verschuiving …

Light intensity and spectral composition notably impact the human circadian rhythm. The human body is a physiological system that regulates its sleep-awake cycle through a constant rhythm of light and darkness. For a long time, the lighting research field has been concerned with understanding this circadian …

In the face of increasingly complex societal challenges, the field of social design is being called upon to deepen its ability to create long-term, systemic impact. This project, conducted with five experienced social designers and one workshop in our ESConference in 2025, explored how systems thinking, …

Of het nu om arbeidsmigratie gaat of om flexwerk, om de inzet van zzp’ers of om vaste contracten: ‘werk’ is een centraal onderwerp in het maatschappelijk en politiek debat. De ‘hardwerkende Nederlander’ lijkt maatgevend voor politieke besluitvorming te zijn geworden. Veel minder gaat het over de inhoud …

Reliability is a constraint of low-power wireless connectivity, commonly addressed by the deployment of mesh topology. Accordingly, power consumption becomes a major concern during the design and implementation of such networks. Thus, a mono-objective optimization was implemented in this work to decrease …

A modified genetic algorithm (MGA) optimization procedure, alongside time series machine learning (ML) classifiers, is proposed to minimize handovers in a digital twin-based visible light communication (VLC) system. Frequent handovers have a direct impact on the overall performance of the VLC system …

This study presents a methodology designed to optimize various parameters of each access point within a Multiple-Input Single-Output (MISO) Visible Light Communication (VLC) system. The primary objective is to enhance both power and spectral efficiencies. A MISO-VLC model is presented based on experimental …
