3. 7. The Functional Microstructure of Al/AlOx/Al Tunnel Junctions

   Författare :Samira Mousavi Nik; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Grain Growth.; Interfaces; Microstructure; AlOx Tunnel Barriers; Transmission Electron Microscopy; Imaging; Spectroscopy; Superconducting Tunnel Junctions;

   Sammanfattning : Josephson junction as a novel superconducting electronic component plays an important role in most small-scale superconducting systems. Particularly the Al/AlOx/Al tunnel junction, a high-performance junction made with a well-established microfabrication technology, is widely used as a building block of many quantum circuits.

4. 8. Measuring quantum systems with a tunnel junction

   Författare :Joachim Wabnig; Jörgen Rammer; Ulrich Eckern; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum mechanics; quantum measurement; tunnel junction; qubit; nanomechanics; noise; Physics; Fysik;

   Sammanfattning : This thesis is concerned with employing the statistics of charge transfer in a conductor as a tool for quantum measurement. The physical systems studied are electronic devices made by nanoscale manufacturing techniques. In this context quantum measurement appears not as a postulate, but as physical process. LÄS MER

5. 9. Reliability-based design of rock tunnel support

   Författare :William Bjureland; Fredrik Johansson; Stefan Larsson; Johan Spross; Lars Rosén; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnad; Jord- och bergmekanik; Soil and Rock Mechanics;

   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

7. 10. Prehospital medical management in Swedish road tunnel incidents

   Författare :Johan Hylander; Anton Westman; Britt-Inger Saveman; Lina Gyllencreutz; Michael Haney; Stephen Sollid; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Road tunnel; incident management; disaster medicine; emergency medical services; e-learning; education; ambulance commander;

   Sammanfattning : Background: The complexity of modern road tunnel systems may delay an efficient rescue effort. Capable decision-making is needed to limit time to care. The Swedish ambulance commander, responsible for the on-scene ambulance personnel, may lack education and experience from managing road tunnel incidents. LÄS MER
