11. Advanced all-fiber optofluidic devices
Sammanfattning : Significant technological advances of the last years have been possible by developments in Optofluidics, which is a field that deals with the integration of optics and microfluidics into single devices.The work described in this thesis is based on five scientific publications related to the use of fiber optic technology to build integrated optofluidic devices.

12. Image-based quantitative infrared analysis and microparticle characterisation for pulp and paper applications
Sammanfattning : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. LÄS MER
13. 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
14. An experimental study of fiber suspensions between counter-rotating discs
Sammanfattning : The behavior of fibers suspended in a flow between two counter-rotating discs has been studied experimentally. This is inspired by the refining process in the papermaking process where cellulose fibers are ground between discs in order to change performance in the papermaking process and/or qualities of the final paper product.

15. An experimental study of the flow of concentrated pulp suspension through a sudden expansion and over a backward facing step
Sammanfattning : Large amounts of pulp suspensions are handled in the pulp and paper industry annually. In order to produce the final product, paper, a lot of energy is required, e.g. for pumping and drying the suspensions. LÄS MER
