1. 16. On some topics in operator theory : An unfinished story about mathematical control

   Författare :Eskil Rydhe; Harmonic Analysis and Applications; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carleson embeddings; complex analysis; control theory; functional models; Hankel operators; harmonic analysis; operator theory; Triebel–Lizorkin spaces; vector-valued analytic functions;

   Sammanfattning : This thesis considers differentiation of non-negative, fractional order, composed with Hardy spacetypeHankel operators. H2-boundedness is characterized in terms of a reproducing kernel thesis. LÄS MER

3. 17. Image Reconstruction and Optical Flow Estimation on Image Sequences with Differently Exposed Frames

   Författare :Tomas Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple camera settings; human visual system; super-resolution; optical flow; high dynamic range; digital camera system; image reconstruction; motion analysis; inverse problem;

   Sammanfattning : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

4. 18. Quantitative vulnerability analysis of electric power networks

   Författare :Åke J. Holmgren; Torbjörn Thedéen; Lars-Göran Mattsson; Terje Aven; KTH; []
   Nyckelord :Safety Analysis; vulnerability; homeland security; risk analysis; network; electric power system; blackout; power law; statistical analysis; graph theory; branching process; game theory; Säkerhetsanalys; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Disturbances in the supply of electric power can have serious implications for everyday life as well as for national (homeland) security. A power outage can be initiated by natural disasters, adverse weather, technical failures, human errors, sabotage, terrorism, and acts of war. LÄS MER

5. 19. On the Einstein-Vlasov system: Stationary Solutions and Small Data Solutions with Charged and Massless Particles

   Författare :Maximilian Thaller; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Static Solutions; Vector Field Method; non-linear wave equation; massless Einstein-Vlasov system; General Relativity; Conformal Einstein Field Equations; Minkowski stability; Vlasov matter; symmetric hyperbolic system; Einstein-Vlasov-Maxwell system;

   Sammanfattning : The Vlasov matter model describes an ensemble of collisionless particles moving through space-time. These particles interact via the gravitational field which they create collectively. In the framework of General Relativity this gravitational field is described by space-time curvature. LÄS MER

7. 20. Risk analysis : a tool in decision-making

   Författare :Per Näsman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : In our daily life we are surrounded by different kind of risks and we constantly strive for better methods to quantify and in the prolongation manage these risks. Every activity involves some risks and there are some kinds of risks and some level of risks that we are unwilling to accept. LÄS MER
