1. 36. In-Line Bit Interleaved Serially Concatenated Coded Modulation

   Författare :ANDERS NILSSON; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; serially concatenated codes; the AWGN channel.; Coded modulation; iterative decoding; in-line bit interleaving; turbo codes;

   Sammanfattning : A communication system using in-line bit interleaved serially concatenated trellis coded modulation (SCTCM) over the additive white Gaussian noise (AWGN) channel is investigated. In-line bit interleaving refers to an interleaving method for which the random bit interleaver is divided into several independent constituent bit interleavers. LÄS MER

3. 37. Glitching the Fabric: Strategies of new media art applied to the codes of knitting and weaving

   Författare :David McCallum; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; glitch art; new media art; weaving; knitting; textile design; artistic research;

   Sammanfattning : The purpose of the research has been to explore the creative possibilities in applying strategies derived from the domain of digital media and glitch art to a range of processes in the domain of textiles—specifically weaving, knitting, bobbin lace—with particular attention to the role of notations and coding in both domains. The enquiry presented in this dissertation is based upon the proposition that there are creative possibilities that arise when approaches and strategies from new-media and glitch art are transferred to some textile processes, and that this is possible because objects of new media and textile objects share features not limited to the grid.

4. 38. Probabilistic design for evaluation of indoor environment

   Författare :Katarina Ljungquist; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Sammanfattning : In recent years indoor environment and indoor air quality has been subjected to extensive worldwide research efforts. Still, at present there are a lack of methods for prediction of risks and consequences for any defined damage to occur, similar to the probabilistic methods used in modern design codes for structures and buildings.

5. 39. Knowledge-Based Systems for Preliminary Design of Structures

   Författare :Per Löfqvist; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis concerns methods for the application of knowledge-based techniques to preliminary structural design. A practical study of these methods is done by developing a prototype for preliminary design of highway bridges (called PREBRI). LÄS MER

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

   Författare :Michael Lentmaier; Institutionen för elektro- och informationsteknik; []
   Nyckelord :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;

   Sammanfattning : 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.
