1. 11. Input Calibration, Code Validation and Surrogate Model Development for Analysis of Two-phase Circulation Instability and Core Relocation Phenomena

   Författare :Viet-Anh Phung; Pavel Kudinov; Cristophe Demaziere; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reactor system code; input calibration; code validation; surrogate model; two-phase circulation flow instability; in-vessel core relocation; genetic algorithm; artificial neural network; Reaktorsystemkod; indata kalibrering; kodvalidering; surrogatmodell; två-fas cirkulationsflöde; instabilitet; härdrelokering i reaktortanken; genetisk algoritm; artificiella neurala nätverk; Fysik; Physics;

   Sammanfattning : Code validation and uncertainty quantification are important tasks in nuclear reactor safety analysis. Code users have to deal with large number of uncertain parameters, complex multi-physics, multi-dimensional and multi-scale phenomena. LÄS MER

3. 12. Nitric oxide in experimental sepsis

   Författare :Peter Dahm; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensive care; Nitric oxide; Sepsis; NO inhalation; Endotoxin; Acute lung injury; ARDS; Nitric oxide synthase; L-NMMA; L-NAME; Anestesiologi; Anaesthesiology; Pigs; intensivvård;

   Sammanfattning : Nitric oxide (NO) is important in the control of blood pressure and organ perfusion. In septic shock, NO produced by inducible NO-synthase (NOS) has been claimed to mediate pathological vasodilation and cell injury, while NO produced by constitutive NOS may be protective in counteracting hypoperfusion and organ injury.

4. 13. Smartphone security : The smartphone as a security device and the public/private production of security

   Författare :Håvard Rustad Markussen; Charlotte Wagnsson; Stefan Borg; Niklas Bremberg; Försvarshögskolan; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Smartphone; security devices; appropriation; public private security; Critical Security Studies; Science and Technology Studies; Political Science; Statsvetenskap;

   Sammanfattning : This thesis examines the smartphone as a security device through a comprehensive summary and four independent papers. The thesis starts from the observation that a central and yet underexplored characteristic of contemporary security politics is that the smartphone, as one especially important piece of consumer technology, is increasingly being transformed into a security device.

5. 14. Essays on stochastic volatility

   Författare :Marcus Nossman; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; volatility; Contagion; jumps; risk premium; MCMC;

   Sammanfattning : This dissertation consists of five papers concerned with the estimation and analysis of financial price processes. The first paper develops a stock price model and analyzes the impact of the US and the regional European stock markets on the local European countries’ stock markets. LÄS MER

7. 15. Bridge Overhang Slabs with Edge Beams : LCCA and Structural Analysis for the Development of New Concepts

   Författare :José Javier Veganzones Muñoz; Costin Pacoste; Raid Karoumi; Lars Pettersson; Rui Vaz Rodrigues; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Overhang slab; Edge beam; Life-cycle Cost Analysis; Non-linear FE-analysis; Design methods; Shear force; Failure mode; Effective width; Minimal width.; Konsolplattor; Kantbalkar; Livscykelkostnadsanalys; Icke-linjär FE-analys; Dimensioneringsmetoder; Tvärkrafter; Brott; Fördelningsbredd; Minimal bredd.; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Sammanfattning : Bridge edge beams are associated with high life-cycle costs because of the need of maintenance, which also causes traffic disturbances. For this reason, the Swedish Transport Administration started a project to find better solutions. One of the proposals was a design without edge beam. LÄS MER
