11. Numerical Investigation of Turbulent Fluid Flow and Heat Transfer in Complex Ducts
Sammanfattning : Th need for a reliable and reasonable accurate turbulence model without specific convergence problem for calculating duct flows in industrial applications has become more evident. In this study a general computational method has been developed for calculating turbulent quantities in any arbitrary three dimensional duct. LÄS MER
12. Adolescent mental health : time trends and validity of self-report measures
Sammanfattning : Background: Studies of time trends of adolescent self-reported mental health suggest an increase of mental health symptoms globally. Unfortunately, several studies within the field have methodological problems, such as short time-period between measurements and different mental health measures over time. LÄS MER
13. Control and Communication-Schedule Co-design For Networked Control Systems
Sammanfattning : In a networked control system (NCS), the control loop is closed through a communication medium. This means that sensor measurements and/or control signals can be exchanged through a communication link. LÄS MER
14. Depression in teenagers and young adults : foundational studies of the new treatment paradigm TARA: Training for Awareness, Resilience, and Action
Sammanfattning : Introduction: Depression in adolescents and young adults is an increasing global health concern and available treatments are not convincingly effective. It is therefore important to develop and test novel treatments to improve treatment outcomes. LÄS MER
15. Towards Fully Automatic Optimal Shape Modeling
Sammanfattning : Shape models and the automatic building of such models have proven over the last decades to be powerful tools in image segmentation and analysis. This thesis makes contributions to this field. The segmentation algorithm typically uses an objective function summing up contributions from each sample point. LÄS MER
