2. 6. Information structures and workflows in health care informatics

   Author : Johan Karlsson; Patrik Eklund; Silvana Quaglini; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Health care informatics; work ows; decision support systems; Informatics; computer and systems science; Informatik; data- och systemvetenskap; Computer Science; datalogi;

   Abstract : Patient data in health care have traditionally been used to support direct patient care. Although there is great potential in combining such data with genetic information from patients to improve diagnosis and therapy decisions (i.e. READ MORE

4. 7. On Boolean Functions in Symmetric-Key Ciphers

   Author : Enes Pasalic; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autocorrelation properties; correlation attacks; nonlinearity; resiliency; Boolean function; Stream ciphers; block ciphers; Informatics; systems theory; Informatik; systemteori;

   Abstract : This thesis discusses new results on the design and the existence of cryptographically strong Boolean functions used in the design of stream and block ciphers. By interlinking theoretical results and computer search some open problems have been solved, that is, we have shown the existence of previously unknown classes of functions. READ MORE

5. 8. Working with the Fogbow : Design and Reconfiguration of services and Participation in E-Government

   Author : Annelie Ekelin; Högskolan i Kalmar; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information Technology; e-government; e-democracy; Technoscience Studies; Informatics; 24-timmarsmyndigheten; serviceutveckling inom offentlig sektor; medborgarperspektiv; Informatik;

   Abstract : This thesis is about the metaphors of the rainbow and the fogbow, investigations and evaluations, public Internet monitors, writing women, reflections and discussions about politics, design and democracy. It is also about the ongoing re-structuring of participation in service design within the development of E-Government. READ MORE

6. 9. Analysis of Some Convolutional Coding Constructions

   Author : Karin Engdahl; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-codes; low-density parity-check convolutional codes; low-density codes; PSK; PAM; QAM; coded modulation; multilevel coding; convolutional codes; multilevel modulation; iterative decoding; Informatics; systems theory; Informatik; systemteori;

   Abstract : This thesis focuses on different convolutional coding constructions for digital communication systems, and on methods to analyze these constructions. The work presented in the thesis can be divided into three main areas; error probability bounds for convolutional codes, analysis of multilevel modulation, and investigation of low-density parity-check convolutional codes.

7. 10. Towards a Theory of Codes for Iterative Decoding

   Author : Michael Lentmaier; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bit error probability; low-density parity-check convolutional code; low-density parity-check code; turbo code; convolutional code; channel coding; iterative decoding; Informatics; systems theory; Informatik; systemteori;

   Abstract : Channel codes in combination with iterative decoding techniques are a both powerful and efficient method to protect data against disturbances in digital communication systems. This thesis deals with various code constructions for block-wise and continuous transmission that have the potential to achieve low bit error rates with iterative decoding, even when operating close to the Shannon limit.
