  • Algebraic phylogenetic reconstruction based on proteins and its application to Persea americana 

    Pérez Gonzalo, Raül (Universitat Politècnica de Catalunya, 2018-09)
    Bachelor thesis
    Open Access
    Phylogenetic reconstruction methods attempt to infer the evolutionary relationships among a group of species. Apart from classical reconstruction methods, new methods have been developed based on algebraic relationships ...
  • Algebraic tools in phylogenomics. 

    Kedzierska, Anna Magdalena (Universitat Politècnica de Catalunya, 2012-03-16)
    Doctoral thesis
    Open Access
    En aquesta tesi interdisciplinar desenvolupem eines algebraiques per a problemes en filogenètica i genòmica. Per estudiar l'evolució molecular de les espècies sovint s'usen models evolutius estocàstics. L'evolució es ...
  • Application of algebraic techniques to phylogenetic reconstruction 

    Cifuentes Fontanals, Laura (Universitat Politècnica de Catalunya, 2015-05)
    Bachelor thesis
    Open Access
    Phylogenetics is the study of the evolutionary relationships among different species through the analysis of sequences of biological data such as DNA. These relationships are usually represented using phylogenetic trees, ...
  • Expectation Maximitzation per a arbres filogenètics| 

    Ibáñez Marcelo, Esther (Universitat Politècnica de Catalunya, 2011-02)
    Master thesis
    Open Access
    Anàlisi exhaustiu del mètode EM aplicat a la reconstrucció filogenètica. Aplicació del mètode per a la reconstrucció de topologies sobre dades simulades sota un model K3. Aplicació i comparació amb altres mètodes de ...
  • Linear invariants for the equal-input evolutionary model 

    Puy Tapia, Alba (Universitat Politècnica de Catalunya, 2017-07)
    Bachelor thesis
    Open Access
    Mathematical models for describing biological systems are becoming more and more important nowadays. In this thesis we will study Markov processes on phylogenetic trees and deeply study the equal-input model, which is the ...
  • Mapping the genetic component of gene expression variance with Mixed Graphical Markov Models : the marginal case 

    Coca Mariné, Ignacio (Universitat Politècnica de Catalunya, 2015-10)
    Master thesis
    Open Access
    Covenantee:  Universitat Pompeu Fabra. Departament de Ciències Experimentals i de la Salut
    En este trabajo desarrollamos la teoría de los modelos gráficos mixtos de Markov (GMMs), y en concreto los modelos heterogéneos. Aplicamos esta teoría a la búsqueda de marcadores génicos que afectan a la varianza de la ...
  • Mathematical topics in phylogenetics 

    Pérez De Los Cobos Hermosa, Cassius Manuel (Universitat Politècnica de Catalunya / Universität Wien, 2017-03)
    Master thesis
    Open Access
    Covenantee:  Max F. Perutz Laboratories
    An evolutionary process is frequently modeled as a sequence of the four bases A,C,G,T, each of them changing independently following a Markov process. The main goal of this project are two: first of all, we wanted to ...
  • Multilinear algebra for phylogenetic reconstruction 

    Garrote López, Marina (Universitat Politècnica de Catalunya, 2015-07)
    Master thesis
    Open Access
    Phylogenetic reconstruction tries to recover the ancestral relationships among a group of contemporary species and represent them in a phylogenetic tree. To do it, it is useful to model evolution adopting a parametric ...
  • Phylogenetic reconstruction based on algebra 

    Cilleruelo Calderón, Gustavo (Universitat Politècnica de Catalunya, 2019-01)
    Bachelor thesis
    Open Access
    In this work we have aimed to discuss the theoretical foundations of quartet reconstruction with algebraic techniques and then implement some new quartet inference measures and test their performance on a subset of the ...
  • Phylogenetics and rank of matrices 

    Garrote López, Marina (Universitat Politècnica de Catalunya, 2014-07)
    Bachelor thesis
    Open Access
    Phylogenetics is the study of the evolutionary relationships of a group of species, and it is usually inferred from the DNA sequences of a set of living species. Thanks to the model developed by Darwin based on natural ...
  • Reconstruction of phylogenetic trees using quartet methods 

    Sabaté Vidales, Marc (Universitat Politècnica de Catalunya, 2014-01)
    Master thesis
    Restricted access - author's decision
    Els arbres filogenètics ajuden a modelitzar l'evolució de les espècies. En aquests arbres, les fulles representen les espècies actuals, l'arrel representa l'ancestre comú a totes aquestes espècies i cada branca un procés ...
