Degradation of polymeric and particulate organic carbon in biofilms
(Doctoral theses at NTNU;2003:101, Doctoral thesis; Peer reviewed, 2003)Polymeric and particulate organic carbon (POM) are fundamental compounds in the global cycling of carbon, and constitute significant amounts of BOD in municipal wastewater. The main objective of this work is to study ... -
Roll-out of model based control with application to paper machines
(Doctoral theses at NTNU;2003:31, Doctoral thesis; Peer reviewed, 2003)A mechanistic nonlinear model of the wet end of paper machine 6 (PM6) at Norske Skog Saugbrugs, Norway has been developed, and used in an MPC application. The MPC provides reduced variability in many key variables, and ... -
Identification of signals describing pairwise interaction in plankton, bacteria and bacteriophage : a study of model, microcosm and lake
(Doctoral theses at NTNU;2003:54, Doctoral thesis; Peer reviewed, 2003)This study concerns interaction between organisms. Such interactions are often studied through organism abundances over periods of time (time-series). Time-series reflect both internal (biological) and external (environmental) ... -
Gas explosions in process pipes
(Doctoral theses at NTNU;2004:79, Doctoral thesis; Peer reviewed, 2004)In this thesis, gas explosions inside pipes are considered. Laboratory experiments and numerical simulations are the basis of the thesis. The target of the work was to study gas explosions in pipes and to develop numer- ... -
A comprehensive scaling up technique for pneumatic transport systems
(Doctoral theses at NTNU;2005:169, Doctoral thesis; Peer reviewed, 2005)The main objective of this investigation was to formulate a comprehensive scaling up technique for designing of pneumatic conveying systems by addressing the whole pipeline together with all accessories. Five different ... -
An experimental and computational study of flow behaviour in bubbling fluidized beds
(Doctoral theses at NTNU;2005:70, Doctoral thesis; Peer reviewed, 2005)Experimental and computational studies of bubble behaviour in gas/solid fluidized beds have been performed. Bubble behaviour depends on particle density, particle size and size distribution and emphasis is given to study ... -
Multivariable process control in high temperature and high pressure environment using non-intrusive multi sensor data fusion
(Doctoral theses at NTNU;2006:38, Doctoral thesis; Peer reviewed, 2006)The main objective of this thesis is to use available knowledge about a process and combine this with measurement data from the same process to extract more information about the process. The combination of knowledge and ... -
Topics in open and closed loop subspace system identification : finite data-based methods
(Doctoral theses at NTNU;2005:228, Doctoral thesis; Peer reviewed, 2006)When subspace identification methods for finite closed loop data sets are presented they are often compared to poor subspace identification methods. The methods presented in this thesis are always compared to the results ... -
