In this paper, a new approach for on-line monitoring and detection of abnormal readily biodegradable substrate (SS) and slowly biodegradable substrate (XS) concentrations, for example due to input of toxic loads from the sewer, or due to influent substrate shock load, is proposed. Considering that measurements of SS and XS concentrations are not available in real wastewater treatment plants, the S

The growing demand for performance improvements of urban wastewater system operation coupled with the lack of instrumentation in most wastewater treatment plants motivates the need for non-linear observers to be used as virtual sensors for estimation and control of effluent quality. This paper is focused on the development of a general procedure for on-line monitoring of activated sludge processes

Todays, industrial robots don't correspond to the needs of the Small and Medium sized Enterprises (SME). Indeed, industrial robots are in many cases too hard to program or too expensive to be used by this kind of enterprises. In order to respond to this need, a European project was created, regrouping five major European robot manufacturers and five leading research institute and universities,

This thesis describes the method of identifying unknown parameters that affect the dynamics of a given quadcopter, also known as grey box system identification. This was primarily done utilising an inertial measurement unit and a motion capture camera system. A system of equations describes the dynamics of the quadcopter, and was later coupled with data gathered while flying, in order to use diffe

In the first part of this thesis discrete time hedging is considered. In paper A an adaptive hedging scheme where the hedge portfolio is re-balanced when the hedge ratios differ by some amount, here denoted eta, is investigated. An expression of the normalized expected mean squared hedging error as eta tends to zero is derived. The result is compared to an earlier result on discrete time hedging o

The topic of this thesis is inspired by an experiment in which a vessel, laying a submarine cable, was provided with forecasts overlaid with satellite observations of significant wave height. During the operation, the vessel was close to an adverse weather area and the personnel on board could confirm that the forecast was not as close to the "ground truth" as the satellite observation was.

Numerous location-based services (LBS) have evolved because of the fast development of mobile Internet for use in commerce, entertainment, security, and other areas. All of these need a precise real-time location-based service with smooth indoor- outdoor transition in highly populated areas. A truly omnipresent location system for both indoor and outdoor settings is still not accessible, despite t

Cameras mounted on boats and in other similar environments can be hard to use if waves and wind cause unwanted motions of the camera which disturbs the desired image. However, this is a problem that can be fixed by applying mechanical image stabilization which is the goal of this thesis. The mechanical image stabilization is achieved by controlling two stepper motors in a pan-tilt-zoom (PTZ) camer
