Saturated hydraulic conductivity (Ks) of the filler layer in grassed swales are varying in the changing environment. In most of the hydrological models, Ks is assumed as constant or decrease with a clogging factor. However, the Ks measured on site cannot be the input of the hydrological model directly. …

Voor het uitvoeren van navigatie zijn er diverse technieken. De voornaamste methode maakt gebruik van Inertial Measusement Units (IMU) en GPS. Echter is het GPS-signaal binnen gebouwen lastig te ontvangen. Ook is het GPS-signaal eenvoudig te spoofen waardoor deze navigatiemethode niet meer bruikbaar …

The estimation of the pose of a differential drive mobile robot from noisy odometer, compass and beacon distance measurements is studied. The estimation problem, which is a state estimation problem with unknown input, is reformulated into a state estimation problem with known input and a process noise …

This paper describes the concept of a new algorithm to control an Unmanned Aerial System (UAS) for accurate autonomous indoor flight. Inside a greenhouse, Global Positioning System (GPS) signals are not reliable and not accurate enough. As an alternative, Ultra Wide Band (UWB) is used for localization. …

To better control the growing process of horticulture plants greenhouse growers need an automated way to efficiently and effectively find where diseases are spreading. The HiPerGreen project has done research in using an autonomous quadcopter for this scouting. In order for the quadcopter to be able …

Kinematical joint analysis during road cycling is a new trend. Reviewing the methods for 2D and 3D lower limb kinematical research, the sensor to segment alignment appeared to be the most challenging part due to unknown orientation with respect to the anatomical joints. A methodology that is suitable …
