1. 16. 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

3. 17. New Perspectives on Analysis and Design of High-Speed Craft with Respect to Slamming

   Författare :Mikael Razola; Anders Rosén; Ermina Begovic; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : High-speed craft are in high demand in the maritime industry, for example, in maintenance operations for offshore structures, for search and rescue, for patrolling operations, or as leisure craft to deliver speed and excitement. Design and operation of high-speed craft are often governed by the hydrodynamic phenomena of slamming, which occur when the craft impact the wave surface. LÄS MER

4. 18. Numerical modelling of geomaterials at failure

   Författare :Alex Spetz; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil-structure interaction; soil plasticity; phase-field fracture model; compression driven fractures; artificial rock; porous rock; finite element analysis; isogeometric analysis; NURBS; numerical methods;

   Sammanfattning : Geotechnical engineering is the science dealing with mechanics of soils and rocks and its engineering applications. Geotechnical engineering projects vary in a wide range, from evaluation of the stability of natural slopes and man-made soil deposits, to the design of earthworks and foundations. LÄS MER

5. 19. Quantum State Analysis : Probability theory as logic in Quantum mechanics

   Författare :Anders Månsson; Anders Karlsson; Gunnar Björk; Ingemar Bengtsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantum; quantum mechanics; state; state analysis; probability; probability theory; logic; Photonics; Fotonik;

   Sammanfattning : Quantum mechanics is basically a mathematical recipe on how to construct physical models. Historically its origin and main domain of application has been in the microscopic regime, although it strictly seen constitutes a general mathematical framework not limited to this regime. LÄS MER

7. 20. Numerical algorithms for nonlinear eigenproblems with eigenvector nonlinearities

   Författare :Parikshit Upadhyaya; Elias Jarlebring; Robert Corless; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerical algorithms; nonlinear eigenproblems; multiparameter eigenvalue problem; nonlinear eigenvalue problem; eigenvector nonlinearities; nepv; scf; p-laplacian; quasi-newton; Numerical Analysis; Numerisk analys;

   Sammanfattning : Eigenproblems and their nonlinear generalizations appear as important problems in a wide variety of fields, ranging from quantum chemistry and vibration analysis to macroeconomics and data science. Hence, the development and analysis of numerical algorithms to solve such problems has a broad multiplicative effect on our ability to answer several crucial scientific questions. LÄS MER
