  1. 1. Topics in convex and mixed binary linear optimization

    Författare :Emil Gustavsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subgradient methods; Lagrangian dual; recovery of primal solutions; inconsistent convex programs; ergodic sequences; convex optimization; mixed binary linear optimization; maintenance scheduling; preventive maintenance; deterioration cost; inconsistent convex programs;

    Sammanfattning : This thesis concerns theory, algorithms, and applications for two problem classes within the realm of mathematical optimization; convex optimization and mixed binary linear optimization. To the thesis is appended five papers containing its main contributions. LÄS MER

  3. 2. A non-probabilistic approach to binary electronic fingerprinting

    Författare :Raoul Dahlin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Electronic fingerprinting deals with the problem of object identification through the use of electronic marks, unique to each object. We consider fingerprinting for the purpose of tracing the origins of illegitimately copied and distributed data, so called pirate copies. LÄS MER

  4. 3. Computational problems in evolution : Multiple alignment, genome rearrangements, and tree reconstruction

    Författare :Isaac Elias; Jens Lagergren; Lior Pachter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distance Methods; Tree reconstruction; Sorting by Transpositions; multiple alignment; ancestral sequences; Computer science; Datavetenskap;

    Sammanfattning : Reconstructing the evolutionary history of a set of species is a fundamental problem in biology. This thesis concerns computational problems that arise in different settings and stages of phylogenetic tree reconstruction, but also in other contexts. LÄS MER

  5. 4. On Sequence Design for Integrated Radar and Communication Systems

    Författare :Momin Jamil Sandhu; Hans-Jürgen Zepernick; Buon Kiong Lau; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The motivation of having a joint radar and communication system on a single hardware is driven by space, military, and commercial applications. However, designing sequences that can simultaneously support radar and communication functionalities is one of the major hurdles in the practical implementation of these systems. LÄS MER

  7. 5. Cyclically permutable codes

    Författare :Anders Lundqvist; Thomas Ericson; Kamil Zigangirov; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A cyclically permutable code is a set of codewords having the property that no codeword is a cyclic shift of another codeword. We study the problem of constructing cyclically permutable codes of large size and low correlation.Cyclically permutable codes are used in code-division multiple-access systems realized by e.g. LÄS MER
