The worldwide rise of skin cancer incidence rates increases the need to investigate ultraviolet radiation (UVR), as it is one of the main causes of skin cancer. 1 A ’ u to UVR varies depending on different factors such as the location of the individual and shielding effects. In this analysis, we evaluated …

Background: With increasing knowledge on the adverse health efects of certain constituents of PM (particulate matter), such as silica, metals, insoluble ions, and black carbon, PM has been under the attention of work safety experts. Previously, we investigated the perceptions of blue-collar workers in …

Workers do not always showcase adequate knowledge on potential long-term health effects and other properties of particulate matter (PM), which may lead to a decreased tendency to work safely in a high-PM environment. To empower workers to work more safely in environments with high PM exposure, we developed …

This paper reports on the first stage of a research project1) that aims to incorporate objective measures of physical activity into health and lifestyle surveys. Physical activity is typically measured with questionnaires that are known to have measurement issues, and specifically, overestimate the amount …

This paper introduces the design principle of legibility as means to examine the epistemic and ethical conditions of sensing technologies. Emerging sensing technologies create new possibilities regarding what to measure, as well as how to analyze, interpret, and communicate said measurements. In doing …

Background: Particulate matter (PM) exposure is an important health risk, both in daily life and in the workplace. It causes respiratory and cardiovascular diseases and results in 800,000 premature deaths per year worldwide. In earlier research, we assessed workers’ information needs regarding workplace …

Dit paper presenteert de voorlopige resultaten van het project SUMMALab waarin een nieuwe ‘meta-lab’ benadering wordt getest. SUMMALab is een meta-lab rond mobiliteits-experimenten in de Metropoolregio Amsterdam, de Metropoolregio Rotterdam-Den Haag en de gemeenten Den Haag, Delft en Rotterdam. Een …

The full potential of predictive maintenance has not yet been utilised. Current solutions focus on individual steps of the predictive maintenance cycle and only work for very specific settings. The overarching challenge of predictive maintenance is to leverage these individual building blocks to obtain …

Electromagnetic fields, or EMF, are ubiquitous in our daily life. Extremely low frequency magnetic fields (ELF MF) are generated by any device using electric current. Especially in workplace situations involving MRI scanners, welding equipment, induction heaters, and power plants, they are known for …

The estimation of the pose of a differential drive mobile robot from noisy odometer, compass and beacon distance measurements is studied. The estimation problem, which is a state estimation problem with unknown input, is reformulated into a state estimation problem with known input and a process noise …
