1. Reliability-based design of rock tunnel support
Sammanfattning : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. LÄS MER
2. On reliability-based design of rock tunnel support
Sammanfattning : Tunneling involves large uncertainties. Since 2009, design of rock tunnels in European countries should be performed in accordance with the Eurocodes. The main principle in the Eurocodes is that it must be shown in all design situations that no relevant limit state is exceeded. LÄS MER
3. Scaling techniques using CFD and wind tunnel measurements for use in aircraft design
Sammanfattning : This thesis deals with the problems of scaling aerodynamic data from wind tunnel conditions to free flight. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the wind tunnel should be corrected. LÄS MER
4. Analysis of Excavation Damage, Rock Mass Characterisation and Rock Support Design using Drilling Monitoring
Sammanfattning : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. LÄS MER
5. Carpal tunnel syndrome. Diagnosis and treatment
Sammanfattning : Carpal Tunnel Syndrome (CTS) is the most common compression neuropathy causing pain, impaired hand function and sick leave. CTS is usually diagnosed based on patient history and clinical tests. In some patients an additional ENeG is done to support the diagnosis. LÄS MER
