1. 1. Taming of the BEAST

   Författare :Maja Loncar; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; tree search; product codes; list distance; list decoding; list-based SISO decoding; ML decoding; MAP decoding; iterative decoding; ISI equalization; BEAST; block codes; Teknik; Signal processing; Signalbehandling;

   Sammanfattning : Modern communication systems are designed to enable reliable and fast information transfer. Therefore, efficient channel coding and decoding strategies are needed, which guarantee sufficiently low probability of erroneous reception with affordable receiver complexity. LÄS MER

3. 2. A Triple Helix of Learning Processes - How to cultivate learning, communication and collaboration among distance-education learners

   Författare :Eva Rydberg Fåhraeus; KTH; []
   Nyckelord :Distance education; collaborative learning; Computer-supported collaborative learning; CSCL; information and communication technology; ICT; forum system; learning processes;

   Sammanfattning : This work focuses on collaborative learning and how it canbe applied and supported in distance education. Previous workindi-cates that distance learners experience more loneliness,technical problems and lack of stimulation than face-to-facelearners do. Collaboration with peers may improve the feelingof connectedness and engagement. LÄS MER

4. 3. On the Design of Error Control Coding for Wireless Communication Systems

   Författare :Carl Fredrik Leanderson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; joint source-channel decoding; Electrical engineering; Elektroteknik; a posteriori probability; soft decoding; list sequence decoding; incremental redundancy; retransmission; low-rate; parallel concatenated; convolutional codes; Turbo codes; Wireless; error correction;

   Sammanfattning : New wireless services such as mobile Internet, multimedia streaming and high speed packet data access are making their way to the market. Availability of low-cost equipment providing high transmission quality and efficient spectrum utilization is crucial to the success of these services. LÄS MER

5. 4. Embedded in a context : the adaptation of immigrant youth

   Författare :Ylva Svensson; Håkan Stattin; Frosso Motti-Stefanidi; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; immigrant youth; adaptation; development; settings; contextual features; linkage; Psykologi; Psychology;

   Sammanfattning : With rising levels of immigration comes a need to know what fosters positive adaptation for the youth growing up in a new culture of settlement.The issue is increasingly studied; however, little of the research conducted has combined a developmental with a contextual approach.

7. 5. Local Social Exposure and Inter-Neighborhood Mobility

   Författare :Alex Giménez de La Prada; Peter Hedström; Eduardo Tapia; Petri Ylikoski; Gianluca Manzo; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ethnic segregation; residential mobility; social interdependency;

   Sammanfattning : Studies on ethnic residential segregation analyze how the inter-neighborhood mobility of individuals shapes their spatial distribution across cities. This literature has shown that the residential choices of households partly depend on the ethnic composition of their neighborhoods: higher in-group shares promote the presence of more in-group members, and vice versa.
