  1. 21. Design for Serviceability - A probabilistic approach

    Författare :Daniel Honfi; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design codes; long-term deflections; structural reliability; serviceability;

    Sammanfattning : In many design situations the acceptable performance of structures is defined by serviceability requirements. To estimate the probability of serviceability failure three main design aspects should be considered: (1) the relevant exposures, (2) the structural response and (3) the performance criteria.

  4. 23. On the Design of Turbo Codes

    Författare :Johan Hokfelt; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel coding; concatenated codes; convolutional codes; iterative decoding; interleaver design; trellis termination; Electronics; Turbo codes; Elektronik;

    Sammanfattning : This thesis is about Turbo codes - codes constructed via parallel concatenation of two recursive convolutional encoders linked by an interleaver. The focus of the work is on the understanding and design of Turbo codes. LÄS MER

  5. 24. Social Awareness Support for Cooperation : Design Experience and Theoretical Models

    Författare :Ovidiu Sandor; Yngve Sundblad; Cristian Bogdan; Steven Benford; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HCI; CSCW; social awareness; user-centred design; Spatial Model; Aether Model; communities; knowledge; Computer science; Datavetenskap;

    Sammanfattning : This thesis addresses the research question of how social awareness support in computer systems for groups and communities can be designed in a successful way. While the field of human-computer interaction has been working with similar questions for more than 20 years, many aspects of people’s cooperation and the way those should be considered in system design still need further consideration and research.

  7. 25. Modelling the Variability of Bending Strength in Structural Timber - Length and Load Configuration Effects

    Författare :Tord Isaksson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; code; reliability-based design; Weibull; test standard; load configuration effect; length effect; weak section; machine grading; visual grading; variability; Structural timber; bending strength; simulation; monte carlo simulation.; Building construction; Byggnadsteknik;

    Sammanfattning : The load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber.
