  1. 1. Constructing Evolutionary Trees - Algorithms and Complexity

    University dissertation from Department of Computer Science, Lund University

    Author : Anna Östlin; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maximum homeomorphic subtrees; Computer science; Consensus trees; Experiment model; Evolutionary trees; Complexity; Computational biology; Algorithms; Data structures; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Biology; Biologi;

    Abstract : In this thesis three general problems concerning construction of evolutionary trees are considered. Algorithms for the problems are presented and the complexity of the problems is investigated. The thesis consists of three corresponding parts. The first part is devoted to the problem of constructing evolutionary trees in the experiment model. READ MORE

  3. 3. Compressed Sensing Algorithms and Applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Dennis Sundman; KTH.; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compressed sensing; greedy pursuits; subspace pursuit; orthogonal matching pursuit; power spectral density estimation; distributed compressed sensing;

    Abstract : The theoretical problem of finding the solution to an underdeterminedset of linear equations has for several years attracted considerable attentionin the literature. This problem has many practical applications.One example of such an application is compressed sensing (cs), whichhas the potential to revolutionize how we acquire and process signals. READ MORE

  4. 4. Distributed connectivity algorithms

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Esther Jennings; [1997]
    Keywords : Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Abstract : The goal of this research is to design efficient distributed algorithms which execute on an arbitrary network to recognize special connectivity structures within that network. In some cases, we also consider the maintenance of these special structures in dynamically changing networks. READ MORE
