2. 16. Convergence Analysis and Design of Multiple Concatenated Codes

   Author : Fredrik Brännström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extrinsic information transfer EXIT function; convergence analysis; Multiple concatenated codes; code search; scheduling; parameter estimation; iterative decoding; EXIT chart; puncturing;

   Abstract : The objective of this thesis is to develop a methodology for designing efficient multiple concatenated coding schemes, consisting of two or more constituent codes, concatenated in serial or in parallel. Extrinsic information transfer (EXIT) analysis is found to be a suitable and versatile analysis tool for such codes and thus, the design methodology is based almost entirely on this technique.

4. 17. Voluntary Information Sharing, Retail Pricing and Firm Performance

   Author : Charlie Lindgren; Siril Yella; Niklas Rudholm; Johan Håkansson; Christian Sandström; Högskolan Dalarna; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Voluntary information sharing; online retailing; e-commerce; price comparison websites; CSR; consumer search;

   Abstract : Online information sharing by firms has created an unprecedented amount of data to analyze by researchers. While conclusions from research should be drawn with basis in sound theory, there has also emerged a need to supplement these theoretical considerations with advanced data collection, storage and analysis as well as reporting to decisionmakers.

5. 18. Convergence Analysis and Improvements for Projection Algorithms and Splitting Methods

   Author : Mattias Fält; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; First-order methods; Convex Optimization; Nonsmooth Optimization; Large-scale Optimization; Iterative Methods; Douglas-Rachford splitting; Line Search;

   Abstract : Non-smooth convex optimization problems occur in all fields of engineering. A common approach to solving this class of problems is proximal algorithms, or splitting methods. These first-order optimization algorithms are often simple, well suited to solve large-scale problems and have a low computational cost per iteration. READ MORE

6. 19. A search for ultra-high energy neutrinos with AMANDA-II

   Author : Christin Wiedemann; Stephan Hundertmark; Lee Thompson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutrinos; Cosmic rays; Ultra-high energy; AMANDA; IceCube; Physics; Fysik; Physics; fysik;

   Abstract : High-energy neutrinos are capable of carrying information over vast distances, and neutrino telescopes such as AMANDA-II provide the means to probe deep inside the violent and energetic interior of the universe. AMANDA-II is located in the glacial ice at South Pole in Antarctica and is optimised to detect Cherenkov emission from neutrino-induced muon tracks with energies above 100 GeV. READ MORE

7. 20. In Search of Security After the Collapse of the Soviet Union : Foreign Policy Change in Denmark, Finland and Sweden, 1988-1993

   Author : Fredrik Doeser; Jan Hallenberg; Michael Karlsson; Olav Knudsen; Teija Tiilikainen; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Denmark; Finland; foreign policy change; perceptions; security cooperation; small states; Sweden; Political science; Statsvetenskap; Political Science; statsvetenskap;

   Abstract : The aim of this study is to explain the evolution of foreign policy in Denmark, Finland and Sweden with regard to Western security cooperation between 1988 and 1993. The study sets out to test two theoretical perspectives on the security cooperation policies of these three small states. READ MORE
