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 …

Methane, the primary component of natural gas, emits less carbon dioxide than other petroleum-based fuels but faces challenges in efficient storage and transportation. Advanced adsorption materials provide a safe and cost-effective solution, with metal–organic frameworks (MOFs) emerging as promising …

The demand for assistive technology is expected to rise alongside the increasing care needs of aging populations. Ambient intelligence, particularly context awareness, offers potential benefits in addressing challenges faced by the healthcare system. In dementia care, context awareness can facilitate …

Reinforcement learning offers a promising approach for personalized, early-stage detection of behavioral events such as agitation in individuals with dementia, particularly when contextual insights from care staff are integrated. Given the scarcity and the ethical constraints of real-world agitation …

Awareness of climate change and stricter emission regulations have accelerated the search for sustainable energy solutions. A central goal is carbon-neutral energy use, minimizing greenhouse gas emissions while ensuring reliable energy supply. In applications with limited grid access—such as festivals, …

In the face of increasingly complex societal challenges, the field of social design is being called upon to deepen its ability to create long-term, systemic impact. This project, conducted with five experienced social designers and one workshop in our ESConference in 2025, explored how systems thinking, …

Privacy concerns can potentially make camera-based object classification unsuitable for robot navigation. To address this problem, we propose a novel object classification system using only a 2D-LiDAR sensor on mobile robots. The proposed system enables semantic understanding of the environment by applying …

Adsorbed natural gas (ANG) storage using metal-organic frameworks (MOFs) is a promising alter- native for efficient natural gas storage at moderate pressures. However, the presence of higher alkanes in natural gas mixtures can significantly affect storage performance by reducing methane adsorption capacity. …

Introduction Resistance to antibiotics is an increasing worldwide problem. Hence, identifying and implementing the use of alternatives to antibiotics is crucial. A prototype app providing evidence-based advice on the use of safe and effective natural medicinal products (NMPs) for acute, uncomplicated …

De oehoe is in Nederland sinds de jaren ’80 sterk in aantal gegroeid: van 7 broedparen naar 103 territoria in 2024. Aanvankelijk was de soort een habitat­specialist die uitsluitend in steengroeves broedde, maar tegenwoordig gedraagt zij zich als bosgeneralist. Dit onderzoek analyseert de verschuiving …
