This paper describes Ivy, an office chair that represents sitting time of an office worker through growing ivy strands. The longer one sits, the more strands will grow onto the chair. By means of a qualitative interface called Ivy, we illustrate a design approach that is currently underrepresented in …

Technology has an ever increasing role in the day to day lives of individuals and societies. To provoke critical thought about the impact of new digital technology, the Technology Impact Cycle Tool (TICT) has been developed. In this paper, three psychological constructs: Performance Expectancy, Effort …

Introduction: Augmented reality enriches online shopping with a new virtual aspect that offers customers the ability to try a product before purchasing it online. It superimposes digital information onto the physical environment which opens up opportunities for businesses involved in eCommerce (Sharma, …

Efforts to involve consumers in the transition towards sustainable diets often presume a degree of reflexivity on the concepts of health and sustainability in the minds of consumers ‘doing healthy and sustainable food’. Departing from the hypothesis that people with type 2 diabetes have been confronted …

Greenhouses are in need of new monitoring tools, as they size grow bigger and bigger but still using old labour intensive methods ways of caring for the crop. HiPerGreen is set out to create a new tool, which can drive onto the pre-existing heating pipes to provide a birds eye perspective for image analysis …

With sufficient electrical energy CO2 from the atmosphere, combined with water, can be converted to hydrocarbons. The first step in converting CO2 into a carbon based fuel is the dissociation of CO2 into CO and O. DIFFER explores the possibilities of this process by using a microwave plasma. This project …

Extrudate swell simulations and experiments have been performed with a viscoelastic tire rubber compound at high flow rates through a circular die. A 3-mode PTT model was fitted onto rheological data of the rubber. The PTT model covers the range of shear rates present in the simulation. Convergence of …

From the thesis: SUMMARY Raspberry-like particles were made with spherical positively charged seed particles and spherical negatively charged smaller particles. The attraction from the small particles onto the surface of the seed particles is a heterocoagulation technique. It has been proven that it …
