21. Approaching a practice for transient CFD simulations of vortex flow meters
Sammanfattning : The usage of Large-Eddy Simulations (LES) in industrial applications makes it possibleto study transient phenomena. The aim of this work is to find a reliable and accurateapproach to transient studies of the internal flow field in a vortex flow meter. LÄS MER
22. Performance monitoring in communication networks
Sammanfattning : Performance monitoring in communication networks, which isthe main topic of this thesis, is an essential part ofperformance and network management. The applications cover anumber of different areas such as daily operations andmaintenance, usage information for billing purposes, customerreports, traffic control, planning, and dimensioning.

23. Three-dimensional mapping of fine structure in the solar atmosphere
Sammanfattning : The effects on image formation through a tilted interference filter in a converging beam are investigated and an adequate compensation procedure is established. A method that compensates for small-scale seeing distortions is also developed with the aim of co-aligning non-simultaneous solar images from different passbands. LÄS MER
24. Inflammation and wound healing following photorefractive keratectomy
Sammanfattning : This study comprises different aspects on the inflammatory and wound healing responses of the eye after Photorefractive Keratectomy (PRK). The purpose was to provide basic information about the inflammatory reaction and the wound healing after surgery. PRK is considered a good technique for surgical correction of and moderate myopia.

25. Installation effects and self diagnostics for ultrasonic flow measurement
Sammanfattning : In the district heating industry, heat meters, consisting among other things of a flow meter, are used for billing purpose. The district heating industry desires accurate and low cost flow measurements. There are mainly two reasons. An under estimation of the flow rate leads to a loss of income for the district heating industry. LÄS MER
