  2. 16. On Young tableau involutions and patterns in permutations

    Author : Erik Ouchterlony; Bruce Sagan; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is dealing with the combinatorics of permutations in three different aspects. In the first two papers, two flavours of pattern avoiding permutations are examined and in the third paper Young tableaux, which are tightly related to permutations via representation theory, are studied.

  4. 17. Combinatorics of genome rearrangements and phylogeny

    Author : Niklas Eriksen; KTH; []
    Keywords : ;

    Abstract : This thesis deals with combinatorial problems taken frombioinformatics. In particular, we study the problem ofinferring distances between bacterial species by looking attheir respective gene orders. We regard one of the gene ordersas a permutation of the other. READ MORE

  5. 18. Aspects of multilinear algebra in statistical analysis of seasonal multivariate time series

    Author : Björn Holmquist; Statistiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Representations of concepts from multivariate statistics are studied using multilinear algebra. Applications are given to the analysis of seasonal multivariate time series. The first paper concerns a class of permutation matrices which are representations of permutation operators on tensor spaces. READ MORE

  6. 19. Folding of the Ribosomal protein S6 : The role of sequence connectivity, overlapping foldons, and parallel pathways

    Author : Ellinor Haglund; Mikael Oliveberg; Neil Ferguson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein folding; protein stability; two-state folding; S6; chevron plot; transition state; parallell pathways; foldon; two-channel landscape; protein engineering; H D-exchange; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : To investigate how protein folding is affected by sequence connectivity five topological variants of the ribosomal protein S6 were constructed through circular permutation.  In these constructs, the chain connectivity (i.e. the order of secondary-structure elements) is changed without changing the native-state topology.

  7. 20. Flexible Interleaving Sub–systems for FEC in Baseband Processors

    Author : Rizwan Asghar; Dake Liu; Joseph R. Cavallaro; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Interleaving is always used in combination with an error control coding. It spreads the burst noise, and changes the burst noise to white noise so that the noise induced bit errors can be corrected. READ MORE
