Voedingsproblemen bij zuigelingen zijn een groeiende zorg binnen de gezondheidszorg, met risico’s op ondervoeding, ontwikkelingsachterstand en psychosociale belasting voor ouders en zorgverleners. In het verpleegkundig kinderzorghuis worden zuigelingen met complexe medische en maatschappelijke problematiek …

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 …

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 …

In de zomer van 2024 was Den Haag het schouwtoneel voor drie aansprekende (top-)sportevenementen: de Tour de France Femmes, het EK beachvolleybal en de Team NL Sport Experience. Vanuit het lectoraat Impact of Sport zijn deze evenementen onderzocht. Dit gebeurde aan de hand van bezoekersenquêtes, observaties, …

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 …

The quality of teaching has a clear impact on student success, but how can good teaching be defined? The European QualiTePE research project, funded by the Erasmus+ programme and involving ten European countries, seeks to adress this question specifically for Physical Education (PE). The QualiTePE instrument …

The Technical Manual for the digital evaluation tool QualiTePE supports users of the QualiTePE tool in creating, conducting and analysing evaluations to record the quality of teaching in physical education. The information on the General Data Protection Regulation (GDPR) instructs users on how to anonymise …

In this paper, we experimentally compare orthogonal frequency-division multiplexing (OFDM) and on-off keying (OOK) modulation in the context of the IEEE 802.15.13-2023 standard at bandwidths up to 50 MHz across a Li-Fi link with distances up to 5 m and a lateral offset up to 51°. Error vector magnitude …
