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, …

The transmission of constant-envelope orthogonal frequency division multiplexing (CE-OFDM) signals, based on electrical phase modulation, was shown to improve the tolerance to noise and the nonlinearity introduced by light-emitting diodes (LEDs) in visible light communication (VLC) systems. This allows …

The performance of a visible light communication (VLC) system based on power domain non-orthogonal multiple access (PD-NOMA) is experimentally evaluated in this paper. The simplicity of the adopted non-orthogonal scheme is provided by the fixed power allocation method at the transmitter and the single …

In this paper, artificial intelligence tools are implemented in order to predict trajectory positions, as well as channel performance of an optical wireless communications link. Case studies for industrial scenarios are considered to this aim. In a first stage, system parameters are optimized using a …

Frontis is een full-service online partner op het gebied van digitale oplossingen in Varsseveld, Gelderland. Frontis is op dit moment bezig om te groeien. Om deze groei te waarborgen heeft Frontis strategische stuurinformatie nodig. Het MT van Frontis heeft op dit moment echter niet concreet welke strategische …

Deze afstudeeropdracht richt zich op inzicht, omgang en mening van de fysiotherapeut over het onderwerp algemeen verkrijgbare (AV) Non-steroidal Anti-Inflammatory Drugs (NSAID’s) en/of paracetamol. Vanuit de praktijk blijkt dat veel fysiotherapeuten onduidelijkheid ervaren in hoeverre zij advies mogen …
