The 5th generation of mobile communications is designed to employ both FR1 and FR2 bands throughout the world. The higher frequency bands (i.e., FR2 n257 26.50 - 29.50 GHz) are posing several challenges to operators and national telecom agencies for performing electromagnetic fields (EMF) measurements. …

Purpose This study aims to qualitatively examine the relationship between the indoor environmental quality (IEQ), lecturers’ and students’ perceived internal responses and academic performance. Design/methodology/approach To capture user experiences with the IEQ in classrooms, semi-structured interviews …

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 …

Background: Pain-related cognitions are associated with motor control changes in people with chronic low-back pain (CLBP). The mechanism underlying this association is unclear. We propose that perceived threat increases muscle-spindle-reflex-gains, which reduces the effect of mechanical perturbations, …

Given the hospitality industry's quick rebound and volume growth in most OECD nations following the Great Recession, the hotel sector in the Netherlands is currently experiencing a severe labour shortage that predates the Covid-19 epidemic (Joppe, 2012). Staff shortages and cost-cutting measures in the …

Purpose: This study aims to qualitatively examine the relationship between the indoor environmental quality (IEQ), lecturers’ and students’ perceived internal responses and academic performance. Design/methodology/approach: To capture user experiences with the IEQ in classrooms, semi-structured interviews …

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 …

The flexible strain sensors have been a topic of interest for multiple studies in the past years. These sensors are soft, bendable mechanisms, which can be applied to substrates through printing or other means. They can indicate longitudinal strain through resistance change, which means that they can …

Over many years we’ve been looking at the emergence of “organized networks” as an alternative concept that could counter the social media platform a priori of gathering (and then exploiting) “weak links.”[1] Organized networks invent new institutional forms whose dynamics, properties, and practices are …

Purpose As oral communication in higher education is vital, good classroom acoustics is needed to pass the verbal message to university students. Non-auditory factors such as academic language, a non-native educational context and a diversity of acoustic settings in different types of classrooms affect …
