The Next Generation EnergyLight

This report is the result from an Integrated Product Design graduation project entitled ‘The Next Generation EnergyLight’. It describes the user-centered research and product development process of a new generation light therapy products. Philips EnergyLight currently sells three light therapy products that claim to make you ‘feel more energetic...

Intrinsic and reflexive contributions to endpoint stiffness during motor learning of unstable force fields

Endpoint stiffness is known to increase in the direction of instability during learning to accurately execute unstable motor tasks. Reflexes might be present in the time interval used for endpoint stiffness calculations suggesting a possible influence of reflexes on endpoint stiffness measurements. In addition, changes of reflexes during motor...

Investigation into quantitative visualisation of suffusion

Suffusion is the process whereby seepage water removes fine grains from a soil, which can result in failure of the soil body. This poses a risk for structures founded on soils that are subjected to large hydraulic gradients, such as encountered near hydraulic dams or river levees. Currently, most experimental work on this topic is geared towards...
