Energieverloop en golfopstuwing bij brekende onregelmatige golven: Metingen en berekeningen
No full textA description is given of a model developed for the prediction of the dissipation of energy in random waves breaking on a beach. The dissipation rate per breaking wave is estimated from that in a bore of corresponding height, while the probability of occurrence of breaking waves is estimated on the basis of a wave height distribution with an upper cut-off which in shallow water is determined mainly by the local depth. A comparison with measurements of wave height decay and set-up, on a plane beach and on a beach with a bar-trough profile, indicates that the model is capable of predicting qualitatively and quantitatively all the main features of the data. A summary of this thesis is published as: Battjes, J.A., Janssen, J.P.F.M. (1978) Energy loss and set-up due to breaking random waves, proc.

Visueel & dynamisch: De stedebouw van Granpré Molière en Verhagen 1915-1950
No full textDe vernieuwing van een in formalisme en academisme vastgelopen vormentaal van architectuur en stadsuitleg tekende zich in de eerste helft van deze eeuw af in twee stromingen: de ene hechtte grote waarde aan zintuiglijke, visuele kwaliteiten en het gebruik van natuurlijke materialen, waarbij grote aandacht werd gegeven aan het specifieke en individuele in de opgave; de andere zocht naar de uiterste zuiverheid van expressie, hetgeen noodzaakte tot eliminatie van wat bijkomstig scheen, waarbij het algemene prioriteit kreeg boven het individuele. Deze stromingen ten onrechte vereenvoudigd tot Delftse School versus het Nieuwe Bouwen of tot Traditionalisme versus Functionalisme komen rond 1950 in hoofdzaak weer in één bedding samen. Ir J.A. Kuiper, schrijver van deze studie, behoort tot de tweede generatie architecten en stedebouwkundigen in het door Granpré Molière en Verhagen in 1916 opgerichte bureau, dat thans als Kuiper Compagnons zijn voortzetting vindt.ArchitectureArchitectur
Optical Flow Based State Estimation for an Indoor Micro Aerial Vehicle
No full textThis work addresses the problem of indoor state estimation for autonomous flying vehicles with an optic flow approach. The paper discusses a sensor configuration using six optic flow sensors of the computer mouse type augmented by a three-axis accelerometer to estimate velocity, rotation, attitude and viewing distances. It is shown that the problem is locally observable for a moving vehicle. A Kalman filter is used to extract these states from the sensor data. The resulting approach is tested in a simulation environment evaluating the performance of three Kalman filter algorithms under various noise conditions. Finally, a prototype of the sensor hardware has been built and tested in a laboratory setup.
