1. On the asymptotic spectral distribution of random matrices : closed form solutions using free independence
Abstract : The spectral distribution function of random matrices is an information-carrying object widely studied within Random matrix theory. In this thesis we combine the results of the theory together with the idea of free independence introduced by Voiculescu (1985). READ MORE

2. Development and evaluation of methods for control and modelling of multiple-input multiple-output systems
Abstract : In control, a common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.

3. Process modelling in pulp and paper manufacture : Application studies with aspects of energy efficiency and product quality
Abstract : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, board and other important components. Improved energy efficiency supports sustainability of the process and the products. READ MORE

4. Essays on Nonlinear Pricing and Welfare
Abstract : The price of a good is said to be nonlinear if the unit price not is constant but depends on some aspect of the quantity (or quality) purchased. This form of pricing is commonly used in many industries, e.g. the electricity and water industries, and has many desirable properties. READ MORE
