1. 11. Implicit structured sequence learning

   Författare :Vasiliki Folia; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : A simple question: Do you know how you manage to speak your native language without making grammatical errors despite the fact that you probably do not know how to describe the grammatical rules you use? Sometimes such simple questions do not have simple answers. The amazing capacity to effectively communicate complex information and thoughts through the medium of language is the result of the way language, and more specifically, linguistic rules are learned: in an implicit manner.

3. 12. Structured LDPC convolutional codes

   Författare :Zhongwei Si; Mikael Skoglund; Ragnar Thobaben; Michael Lentmaier; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : LDPC convolutional codes, also known as spatially coupled LDPC codes, have attracted considerable attention due to their promising properties. By coupling the protographs from different positions into a chain and terminating the chain properly, the resulting convolutional-like LDPC code ensemble is able to produce capacity-achieving performance in the limit of large parameters.

4. 13. Socially structured health behaviors : Studies of social inequality in adolescent and young adult physical activity, alcohol consumption, and smoking in Sweden

   Författare :Laura Wells; Viveca Östberg; Magnus Nermo; Olof Östergren; Curt Hagquist; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; health behaviors; physical activity; alcohol consumption; smoking; health lifestyle; social inequalities; socioeconomic position; education; school performance; adolescents; young adults; life course perspective; folkhälsovetenskap; Public Health Sciences;

   Sammanfattning : Health behaviors contribute to the Swedish national disease burden and to social inequalities in health. This thesis aims to increase our knowledge of whether, when, and how health behaviors become socially structured during early life in Sweden. LÄS MER

7. 15. Efficient Partitioning of Dynamic Structured Grid Hierarchies

   Författare :Johan Steensland; Michael Thuné; Jarmo Rantakokko; Charles Norton; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scientific computing; partitioning; structured grids; adaptive mesh refinement; dynamic load balancing; Beräkningsvetenskap; Scientific Computing;

   Sammanfattning : This thesis aims at decreasing execution time for large-scale structured adaptive mesh refinement (SAMR) applications executing on general parallel computers. The key contributions are (1) A conceptual dynamically adaptive meta-partitioner able to select and configure an appropriate partitioning technique, based on application and computer state, and (2) A characterization of new and existing domain-based partitioners, enabling a mapping from application and computer state onto appropriate partitioners, and (3) Sketched scalable solutions, expressed in terms of natural regions and expert algorithms, for the problem to efficiently partition large-scale SAMR applications with deep grid hierarchies executing on general parallel computers, and (4) A software partitioning tool Nature+Fable, implementing the greater parts of these sketched scalable solutions and engineered as part of the meta-partitioner.
