16. A Novel Fiber Interaction Method for Simulation of Early Paper Forming
Sammanfattning : In the forming section of a paper machine, a fiber suspension is flowing down onto a forming fabric, and a paper structure is formed. By using computer simulations this process can be studied, attaining new knowledge helping to improve paper quality and machine efficiency. LÄS MER
17. Online characterization of wood pulp : foundations for a photoacoustic sensing technique
Sammanfattning : Today, there is an increasing demand in the paper industry for better utilisation of the raw material and improved energy efficiency. Also, the increasing use of recycled paper in the manufacturing process leads to a situation where the knowledge of pulp properties needs to be improved and controlled. LÄS MER
18. Parameter and State Estimation with Information-rich Signals
Sammanfattning : The complexity of industrial systems and the mathematical models to describe them increases. In many cases, point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. LÄS MER
19. Transitional and turbulent flow in porous media
Sammanfattning : Fluid flow through porous media takes place in many natural processes such as ground water flows, capillary flows in plants and flow in human organs and muscles. It is also of outmost importance to have knowledge of this flow in a number of industrial processes such as paper making, making of fibre boards, composites manufacturing, filtering, forming and sintering of iron ore pellets and drying and impregnation of wood.

20. Development and characteristics of a fully recycled CF/PP composite
Sammanfattning : The increasing industrial use of carbon fibre in e.g. aircraft and wind turbines calls for strategies for their recovery and possible reuse. In addition, tremendous amount of energy is needed to be able to manufacture pristine carbon fibres. LÄS MER
