1. Statistical tools for ultrasonic analysis of dispersive fluids
Sammanfattning : This thesis focuses on the possibility of using ultrasonic measurement techniques for energy gas characterization. The idea is to combine both on-line flow measurements with non-invasive fluid characterization in the same measurement setup using the same sensor(s). LÄS MER
2. Ultrasonic measurement principles : modeling, identification, and parameter estimation
Sammanfattning : This thesis presents contributions within the fields of ultrasonic modeling and measurement technology, with focus on solutions to difficult modeling and measurement problems. The work is divided into two categories: 1) processing of measurements obtained under non-ideal conditions, such as unsynchronized, distorted, and superimposed signals; 2) estimating acoustic models and parameters from materials, fluids, fluid mixtures, and thin-layered structures.

3. Ecology of juvenile turbot and flounder in the Central Baltic Sea : Implications for recruitment
Sammanfattning : Our understanding of turbot and flounder ecology in the Baltic Sea is insufficient for sound management decisions. This thesis aims to fill some gaps in current knowledge by providing information of the ecology of turbot and flounder within their juvenile habitat, and to relate these findings to issues assumed relevant for recruitment variation.

4. Towards reliable seismic hazard assessment in underground mines
Sammanfattning : Seismic hazard is used for national, regional, and local level to ensure safe constructions in specific areas. In the mining industry this information is valuable e.g. to design infrastructure or rock support, to reduce the risk of rock burst and to minimise the risk of locating personnel in hazardous areas.

5. Draw control strategy for sublevel caving mines : A probabilistic approach
Sammanfattning : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. LÄS MER
