  2. 21. Some results on fast correlation attacks

    Author : Fredrik Jönsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; stream ciphers; linear feedback shift registers; cryptology; correlation attacks; cryptanalysis; Teknik; Informatics; systems theory; Informatik; systemteori;

    Abstract : This thesis presents new results on fast correlation attacks on stream ciphers. In particular, fast correlation attacks on stream ciphers containing linear shift registers with an arbitrary number of taps, are considered. A general introduction to stream ciphers and correlation attacks is given. READ MORE

  4. 22. An Encounter with Convolutional Codes over Rings

    Author : Emma Wittenmark; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Data- och systemvetenskap; Telecommunication engineering; computer technology; direct sum decomposition of a ring; Systems engineering; minimal trellis; generator matrix properties; code properties; convolutional codes; codes over rings;

    Abstract : Convolutional codes is one possibility when there is a need for error-correcting codes in communication systems. Using convolutional codes over rings is a relatively new approach. READ MORE

  5. 23. A Markov Process on Cyclic Words

    Author : Erik Aas; Svante Linusson; Sylvie Corteel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The TASEP (totally asymmetric simple exclusion process) studied here is a Markov chain on cyclic words over the alphabet{1,2,...,n} given by at each time step sorting an adjacent pair of letters chosen uniformly at random. READ MORE

  6. 24. A Halich Karaim Bible Translation

    Author : Zsuzsanna Olach; Éva Ágnes Csató Johanson; Lars Johanson; Mats Eskhult; Marcel Erdal; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Karaim; Halich Karaim; Bible Translation; Code Copying; Turkiska språk; Turkic languages;

    Abstract : This dissertation is a corpus-based analysis of a translation of the Hebrew Bible into Halich Karaim, a Kipchak Turkic variety previously spoken in the present-day Ukraine. The corpus analysed in the thesis comprises sixty selected pages of a 596 page manuscript written in the Hebrew alphabet. READ MORE

  7. 25. On Linear Transmission Systems

    Author : Dzevdan Kapetanovic; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO systems; Precoding; Information Theory; Single Carrier Systems; Linear Modulation; Faster-than-Nyquist Signaling.;

    Abstract : This thesis is divided into two parts. Part I analyzes the information rate of single antenna, single carrier linear modulation systems. The information rate of a system is the maximum number of bits that can be transmitted during a channel usage, and is achieved by Gaussian symbols. READ MORE
