Mice Tracking Using Infrared Subcutaneous Implants for Error Detection

The objective of this thesis was to develop a rodent tracker using the FlashTrack implants, and allow for tracking data to be used for behavioural research. The task was split into three main problems: detection, tracking and error detection. The detection was solved with basic image processing. The first step was background removal, using...

Development of sway reduction control for the Jacket Lift System of Pioneering Spirit

Pioneering Spirit, Allseas's largest pipelay vessel, will be outfitted with a novel Jacket Lift System (JLS). A jacket refers to the steel frame which supports the topside of a fixed offshore platform. The Pioneering Spirit was already capable of lifting the topsides of offshore platforms, like the former oil platform Brent Delta, but would have...

Observing Solid Concentrations in a Vertical Hydraulic Transport System

At large oceans depths (5000m) manganese nodules are formed, these are rock shaped objects that contain various rare earth metals, Royal IHC is currently developing equipment to bring these nodules to the shore. The nodules will be transported to the water surface using a Vertical Transport System (VTS).<br/><br/>In the VTS insight of the...

A parametric study in the force production of surging and pitching wings using a deconvolution Kalman filtering approach

A novel filtering method is implemented for the force measurements for typical flapping-wing measurement setups, taking into account the structural dynamics of the setup. With this filter, the temporal resolution of the usable signal is increased. Experiments are performed for surging and pitching wings, relevant for flapping wing flight, where...

Monitoring the dynamic behaviour of a free-hanging deep sea riser

In deep sea mining polymetallic nodules are harvested that are found in large parts of the oceans at depths of up to 6000 metres. A deep sea mining system collects such nodules using a seabed crawler and transports them to a continuously sailing ship by pumping them via a jumper through a free-hanging riser. The position of the seabed crawler...

Fixed-Wing UAV Integrated Navigation with Low-Cost IMU/GPS

Today, there is an increase in the use of Unmanned Aerial Vehicles (UAV's), for applications that can be considered dull, dirty or dangerous when compared to those applications of conventional aircraft or helicopters. To further increase the use of UAV's, their navigation filters must be robust and reliable. The trend in current autopilot...

Het gebruik van Kalman filtering bij het bestuderen van kustgedrag

Voor de kust tussen IJmuiden en Scheveningen zal met behulp van Kalmanfiltering worden onderzocht in hoeverre enkele eenvoudige kustmodellen door metingen worden bevestigd, c.q. bijgesteld. De beschouwde modellen lijn de eenlijntheorie en de tweelijntheorie. Het rapport is als volgt ingedeeld. In hoofdstuk 2 wordt de theorie van het filter...
