  1. 1. On Woven Convolutional Codes

    Author : Stefan Höst; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; iterative decoding; woven convolutional code; cascaded convolutional code; free distance; convolutional code; active distance; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Concatenation of several conventional convolutional encoders is a both powerful and practical method to obtain encoding schemes that are attractive for use in communication systems where very low error probabilities are needed. This thesis is devoted to woven convolutional codes, a construction where the constituent codes are woven together in a manner that resembles the structure of a fabric. READ MORE

  2. 2. 3D-woven Reinforcement in Composites

    Author : Fredrik Stig; Stefan Hallström; Dan Zenkert; Andrew Long; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Composites made from three-dimensional (3D) textile preforms can reduce  both the weight and manufacturing cost of advanced composite structures  within e.g. aircraft, naval vessels and blades of wind turbines. READ MORE

  4. 4. Mille-feuille Filter : A Non-woven Nano-cellulose Based Virus Removal Filter for Bioprocessing

    Author : Simon Gustafsson; Albert Mihranyan; Jonas Lindh; Kurt Brorson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virus filtration; mille-feuille; downstream; nanocellulose; protein throughput; protein recovery; LRV; MVM; Cladophora; non-woven filter;

    Abstract : Virus removal filters, produced from synthetic surface-modified polymers or regenerated cellulose by phase inversion, are vital to the production of therapeutic proteins such as monoclonal antibodies and plasma proteins. Use of these filters is also one of the most expensive purification steps in the downstream processing of proteins due to high sales price and being limited to a single use. READ MORE

  5. 5. Macroscale Modelling of 3D-Woven Composites: Inelasticity, Progressive Damage and Final Failure

    Author : Carolyn Oddy; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D-woven composites; Anisotropy; Damage; Inelasticity; Phase-field; Failure;

    Abstract : Composites with 3D-woven reinforcement have been slowly making their way into different industrial applications. The interlacement of yarns, not only in-plane but also through-thickness, means that in many applications 3D-woven composites can outperform their laminated counterparts. READ MORE
