Selection and development of innovative design alternatives: Ethical, social and uncertainty issues

Innovative engineering design shapes the development of novel technologies and is ethically as well as socially relevant, because it affects what kind of possibilities and consequences will arise. A major challenge in engineering design work on innovative technologies is the multitude of uncertainties in the form of known unknowns, unknown...

Small Railway Stations: A concept for improving passengers' travel experience and the stations' functionality

Introduction Most people prefer waiting at big railway stations above waiting at SRS's. While SRS's are the engine’s which feed passengers to the big railway stations, limited attention has been given to this important group of stations. Since a couple of years the focus points of the NS includes the improvement of SRS's, it is of importance to...

Sand Erosion in Cold Heavy Oil Production with Sand

Cold Heavy Oil Production with Sand (CHOPS) is a production method to produce heavy oil (>100 cP). It is mainly applied onshore Canada in unconsolidated sand reservoirs. Different theories exist about how the erosion process takes place inside the reservoir. This research project focused on the influence of the grain stress on the sand erosion...

Sediment Concentration due to Currents and Irregular Waves: The effects of grading of the bed material: analysis report

Coastal changes are often the result of changes in the sediment transport rates along a coast. For the prediction of coastal changes, it is therefore necessary to accurately compute the transport rates. For the computation of longshore transport rates, a number of models is available, for example the TRANSPOR model by Van Rijn [1993]. In most of...
