We present a method for measuring gait velocity using data from an existing ambient sensor network. Gait velocity is an important predictor of fall risk and functional health. In contrast to other approaches that use specific sensors or sensor configurations our method imposes no constraints on the elderly. …

Flexigrow is a project which analyzes the performance of an all-electric neighborhood of energy efficient houses here in the Netherlands. The goal of this project is to determine whether or not the houses are performing as well as expected and how we might improve their performance using different infrastructure …

The production of biogas through anaerobic digestion is one of the technological solutions to convert biomass into a readily usable fuel. Biogas can replace natural gas, if the biogas is upgraded to green gas. To contribute to the EU-target to reduce Green House Gases emissions, the installed biogas …

Present-day students are expected to be lifelong learners throughout their working life. Higher education must therefore prepare students to self-direct their learning beyond formal education, in real-life working settings. This can be achieved in so-called hybrid learning configurations in which working …

In this paper, the performance gain obtained by combining parallel peri- odic real-time processes is elaborated. In certain single-core mono-processor configurations, for example, embedded control systems in robotics comprising many short processes, process context switches may consume a considerable …

A laboratory test setup is built to transfer and actively stabilize an ultrastable signal, obtained from a laser with sub-Hz linewidth, trough a 5 km long fiber link. The fiber noise is measured and compensated via a feedback loop acting on an AOM that can change the frequency (and therefore the phase) …

This paper shows how locally available biomass is used to its full potential as source for renewable energy and bio-based products with a multidimensional integrated approach. The use of locally available biomass streams, which are currently hardly or not optimally used, is the center of the project …

Due to the changing role and context of (new) universities, roles of lecturers are renewed and diversified. In this study, weekly written narratives from lecturers on their development in novel researcher roles at new universities are collected over time and analyzed correspondingly. Understanding how …

Social work organizations, research institutions, government agencies and housing associations are partners in many urban redevelopment programmes. Combining the interests of these organizations can be an interesting management challenge, and developing information systems to suit the combined information …
