  1. 1. Adaptive random walks on graphs to sample rare events

    University essay from Stockholms universitet/Fysikum

    Author : David Christoph Stuhrmann; [2023]
    Keywords : statistical physics; graphs; random walks; large deviation theory; adaptive power method; dynamical phase transition;

    Abstract : In this thesis, I study fluctuations and rare events of time-additive observables of discrete-time Markov chains on finite state spaces. The observable of interest is the mean node connectivity visited by a random walk running on instances of an Erdős-Rényi (ER) random graph. READ MORE

  3. 2. Study of CO Emission in Nine Hot Dust-Obscured Galaxies at z ∼3

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Timothy Faerber; [2021]
    Keywords : Galaxies; high-z; AGN; starburst; quasar; evolution; cosmology;

    Abstract : Massive galaxies evolve through different phases including starburst-dominated and active galactic nuclei (AGN)-dominated phases. These phases are predicted to be prevalent at earlier times (z ∼ 2 − 3). READ MORE

  4. 3. Phase stability and mechanical properties of M4AlB4 (m=Cr, Hf, Mo, Nb, Ta, Ti, V, W, Zr) from first principles

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Adam Carlsson; [2019]
    Keywords : MAB phase Cr4AlB4 Stability dynamical thermodynamical mechanical;

    Abstract : The recent discovery of Cr4AlB4, a laminated ternary metal boride belonging to the family of layered MAB-phases, where the transition metal boride layers are interleaved by an A layer, has spurred theoretical investigation for novel M4AlB4 phases. In this study, first-principles calculations were applied in order to investigate the thermodynamical stability and mechanical properties of M4AB4 where M = Cr, Hf, Mo, Nb, Ta, Ti, V, W, Zr while the A layer was kept fixed as Al.

  5. 4. Numerical Control: Performance Analysis and Implementation Issues

    University essay from KTH/Reglerteknik

    Author : Nicolas Vinikoff; [2012]
    Keywords : ;

    Abstract : In this thesis, a digitalization method with nite word-length (resolu- tion N ) of a given stable analog controller guaranteeing the minimum dierence in terms of frequency responses is treated. The challenge has consisted in nding a relevant frequency responses mismatch met- ric and in relating it to the word niteness issue. READ MORE
