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 user experience of our daily interactions is increasingly shaped with the aid of AI, mostly as the output of recommendation engines. However, it is less common to present users with possibilities to navigate or adapt such output. In this paper we argue that adding such algorithmic controls can be …

Predictive maintenance is the promise of the future in infrastructure asset management. Predictive maintenance more and more uses sensor data. Sensors are relatively cheap, and their data mostly comes in huge quantities. Trends or flags may be observed in the data, sometimes with traditional statistical …

Export shipments arriving late at the freight building of KLM Cargo at Schiphol Airport is a trigger to deviations in the standard acceptance process. These Late Shows are currently handled ad-hoc making it difficult to plan and predict these events. In addition, shipments arriving on time is currently …

Inspired by the notion that online sources had declared Final Fantasy VII Remake as a celebration of queerness, this study analyzes the ways in which the game has been adjusted. After an exploration of the concepts of queergaming and queer representation, the promotion of homophobia and heteronormativity …

Increasingly, Design Thinking has influence beyond the confines of traditional design disciplines and expands its’ role in connecting domains and integrating resources. This study focusses on the changing role of design researchers involved in interdisciplinary research projects, following a Research-through-Design …

Digital innovation in education – as in any other sector – is not only about developing and implementing novel ideas, but also about having these ideas effectively used as well as widely accepted and adopted, so that many students can benefit from innovations improving education. Effectiveness, transferability …

"Despite many efforts, people with a refugee background still have great difficulties to find a job on the Dutch labour market. This has adverse consequences for the economic independence of people with a refugee background, their social connections, personal development, health and general well-being, …

Graphs are ubiquitous. Many graphs, including histograms, bar charts, and stacked dotplots, have proven tricky to interpret. Students’ gaze data can indicate students’ interpretation strategies on these graphs. We therefore explore the question: In what way can machine learning quantify differences in …

In this project we take a look at the laws and regulations surrounding data collection using sensors in assistive technology and the literature on concerns of people about this technology. We also look into the Smart Teddy device and how it operates. An analysis required by the General Data Protection …
