We report the detection of tryptophan at sub-ppb levels for a fluorometer based on Fresnel lenses and low-cost electronics. These fluorometers can be used to detect fecal contamination in drinking water, indicated by tryptophan-like fluorescence.

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 …

This thesis studies the factors that influence physical distribution structure design. Distribution Structure Design (DSD) concerns the spatial layout of the distribution channel as well as the location(s) of logistics facilities. Despite the frequent treatment of DSD in supply chain handbooks, an empirically …

Covid-19 made us realize that educational practices in higher education must change AND can change. A possible solution for practicing lab work is working in a remote lab: a real lab in which students and the equipment/instruments are physically apart. The concept of printed touchless electronics was …

Limestone is a sedimentary rock that is composed mostly of calcium carbonate (CaCO3). Limestone is, among many applications, used as a raw material for the manufacture of quicklime. When limestone is heated, the stone calcinates and quicklime is formed. The primary use of quicklime is in the steel and …

The 2021 “HANW@TTS interface” internship project was executed by a third-year student from the Electronics Engineering Department of HAN University of Applied Sciences. One company supervisor and one supervising teacher guide the student during the internship. The objective of this project can be …

Young pediatric patients who undergo venipuncture or capillary blood sampling often experience high levels of pain and anxiety. This often results in distressed young patients and their parents, increased treatment times, and a higher workload for healthcare professionals. Social robots are a new and …

Scholars in sustainable consumption increasingly highlight the limitations of “weak sustainable consumption” approaches to overcome the challenges of the current environmental crisis. While efforts to enable cleaner production and circular flows of materials are necessary and important, progress in environmental …

In this work, the concept of an Artificial Intelligence-based (AI) Digital Twin (DT) of an aircraft system is introduced, with the goal to improve the corresponding MRO Operations. More specifically, the current study aims to obtaining knowledge on the optimal placement of sensors in an ideal Power Electronics …

This paper studies the factors that drive distribution structure design (DSD), which includes the spatial layout of distribution channels and location choice of logistics facilities. We build on a generic framework from existing literature, which we validate and elaborate using interviews among industry …
