  1. 11. Testing Direct Coupling Analysis on HP Model Proteins

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Mustafa Kadhim; [2018]
    Keywords : Direct Coupling Analysis HP model proteins; Physics and Astronomy;

    Abstract : Direct coupling analysis (DCA) models correlations in sets of related (homologous) protein sequences using a Potts-like spin model ansatz. From the couplings of the Potts model, derived by inverse statistical mechanics, residue-pair contacts in the 3D structure of the protein are predicted. READ MORE

  3. 12. Modeling state of waste water system in Dakar, Senegal

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Jacob Schennings; Rasmus Pettersson; [2016]
    Keywords : ;

    Abstract : This report contains a method to mathematically determine the condition of pipes in a sewer system in Dakar, Senegal. First a survival analysis model is established based on probability density functions. The functions are then fitted to a data set consisting of the age of the sewer pipes and their inspected status.

  4. 13. Likelihood-based classification of single trees in hemi-boreal forests

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Simon Vallin; [2015]
    Keywords : Classification of single trees; likelihood-based classification; naive bayes classifier;

    Abstract : Determining species of individual trees is important for forest management. In this thesis we investigate if it is possible to discriminate between Norway spruce, Scots pine and deciduous trees from airborne laser scanning data by using unique probability density functions estimated for each specie.

  5. 14. On Climate Change and Its Impact on Extreme Rainfall in Bangladesh

    University essay from Lunds universitet/Matematisk statistik

    Author : Nasrin Sultana; [2015]
    Keywords : Key words: generalized extreme value distribution; generalized Pareto distribution; return level; bivariate extreme value distribution; bivariate generalized Pareto distribution; climate change; dependence.; Mathematics and Statistics;

    Abstract : In recent years extreme value distributions have attracted a fair amount of attention in literature for risk assessment based on climate data. This thesis focuses on modeling a series of rainfall data over 58 years in the period 1954-2012 recorded at five different stations in Bangladesh. READ MORE

  6. 15. Estimating the Term Structure of Default Probabilities for Heterogeneous Credit Porfolios

    University essay from KTH/Matematisk statistik

    Author : Felix Bogren; [2015]
    Keywords : ;

    Abstract : The aim of this thesis is to estimate the term structure of default probabilities for heterogeneous credit portfolios. The term structure is defined as the cumulative distribution function (CDF) of the time until default. Since the CDF is the complement of the survival function, survival analysis is applied to estimate the term structures. READ MORE
