Indoor service robots need perception that is robust, more privacy-friendly than RGB video, and feasible on embedded hardware. We present a camera-free 2D LiDAR object detection pipeline that encodes short-term temporal context by stacking three consecutive scans as RGB channels, yielding a compact YOLOv8n …

Background and aim. To improve the indoor environmental quality (IEQ) in schools, the Dutch government issued a program of requirements (PoR) “Fresh Schools”. This study aims to determine the effect of adopting class A (high IEQ) or B (moderate IEQ) of this PoR on students’ comfort and performance. Requirements …

Groene schoolpleinen bieden unieke kansen voor onderwijs, maar er is nog veel behoefte aan voorbeelden voor het dagelijks gebruik. In dit onderzoek hebben we gekeken hoe onderwijs op groene schoolpleinen in Nederland wordt gegeven. We onderzochten welke vakken op groene schoolpleinen worden gegeven, …

This study examines the impact of moderate and high lighting and indoor air quality (IAQ) conditions on students’ well-being during a regular academic course in higher education. To determine the precise contribution of these two indoor environmental factors, students’ perceptions of their well-being …

This research explored the use of deep learning to classify impact events on wind turbine blades using spectrogram images. Audio data were recorded through indoor and outdoor simulations using smartphones. The data preparation process involved converting stereo recordings to mono, applying downcasting …

The Dutch government's "Fresh Schools" program aims to improve indoor environmental quality in schools by setting requirements for school buildings. School management must choose an indoor environment quality class (A, B, or C). This study examines the impact of different reverberation times (RT) on …
