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 …

An energy harvesting device for obtaining energy from drops without needing of moving the drops along the device, in a reduced scale and combinable with other types of harvesting devices, the energy harvesting device comprising one or more triboelectric generators comprising a bottom electrode, a friction …

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 …

A resource optimization methodology is proposed for application in long range wide area networks (LoRaWANs). Using variable neighborhood search (VNS) and a minimum-cost spanning tree algorithm, it reduces the implementation and the maintenance costs of such low power networks. Performance evaluations …

INTRODUCTION: Entrustable professional activities (EPAs) are used during training but may also have significance after graduation. This domain has not yet been much explored. We investigated the use of EPAs among alumni of Master Physician Assistant programs in the Netherlands, where EPAs have been used …

The nonlinearity induced by light-emitting diodes in visible light communication (VLC) systems presents a challenge to the parametrization of orthogonal frequency division multiplexing (OFDM). The goal of the multi-objective optimization problem presented in this study is to maximize the transmitted …

Dit werk beschrijft de fabricage van een op titaniumcarbide nanodeeltjes gebaseerde inkjet-geprinte flexibele bidirectionele stromingssensor. Het ontwerp van de stromingssensor bestaat uit een met inkjet geprinte titaniumcarbide piëzoresistieve spanningsmeter op een polyester cantilever. De sensoren …

This study investigates factors predicting hospitality management students’ intention to enter employment in the hospitality industry upon graduation. Survey data were collected from 591 hospitality management students in a hotel management school in the Netherlands. Results of multiple regression analyses …

Laboratory experiments are important pedagogical tools in engineering courses. Restrictions related to the COVID-19 pandemic made it very difficult or impossible for laboratory classes to take place, resulting on a fast transition to simulation as an approach to guarantee the effectiveness of teaching. …

For almost 25 years, the goal of the RoboCup has been to build soccer robots capable of winning against the FIFA World Champion of 2050. To foster the participation of the next generation of roboticists, the RoboCupJunior competition takes place in parallel and provides a similar challenge of appropriate …
