  1. 16. Markov chain Monte Carlo for the reconstruction of lineage trees from single-cell DNA data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Iris Balcázar Castell; [2019]
    Keywords : ;

    Abstract : The purpose of this study is to infer evolutionary trees through the Markovchain Monte Carlo algorithm (MCMC) [1] based on whole-genome single cell DNA sequencing data. By using MCMC we obtain likely tree structure samples according to the cells’ somatic point mutations in our data. READ MORE

  3. 17. An application of Bayesian Hidden Markov Models to explore traffic flow conditions in an urban area

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Lovisa Andersson; [2019]
    Keywords : Bayesian statistics; hidden states; Markov chain; traffic flow modeling; filtering; smoothing; most probable state sequence; MCMC; Hamiltonian Monte Carlo; No-U-Turn sampler;

    Abstract : This study employs Bayesian Hidden Markov Models as method to explore vehicle traffic flow conditions in an urban area in Stockholm, based on sensor data from separate road positions. Inter-arrival times are used as the observed sequences. READ MORE

  4. 18. Searching for Exoplanets in K2 Data

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Iskra Georgieva; [2018]
    Keywords : exoplanets; transit method;

    Abstract : The field of extrasolar planets is undoubtedly one of the most exciting and fast-moving in astronomy. Thanks to the Kepler Space Telescope, which has given us the Kepler and K2 missions, we now have thousands of planets to study and thousands more candidates waiting to be confirmed. READ MORE

  5. 19. Point source carbon capture by porous inorganic carbonates

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Jonas Hultberg; [2018]
    Keywords : Carbon capture; Gas separation; Adsorbent; Inorganic carbonates; Point source; Carbon dioxide; Kolavskiljning; Adsorbenter; Oorganiska karbonater; Punktkälla; Koldioxid;

    Abstract : Mesoporous inorganic carbonates (MIC) was synthesized and tested as adsorbents for CO2, using vacuum and temperature swing adsorption. Mesoporous magnesium carbonate (MMC), mesoporous calcium carbonate (MCC) and mesoporous calcium magnesium carbonate (MCMC), all included in MIC, are exceedingly porous with an amorphous structure.

  6. 20. P-SGLD : Stochastic Gradient Langevin Dynamics with control variates

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Andrea Bruzzone; [2017]
    Keywords : Big Data; Bayesian Inference; MCMC; SGLD; Estimated Gradient; Logistic Regression;

    Abstract : Year after years, the amount of data that we continuously generate is increasing. When this situation started the main challenge was to find a way to store the huge quantity of information. READ MORE
