  1. 1. Free Energy and Surface Forces in polymer systems: Monte Carlo Simulation Studies

    Författare :Andrei Broukhno; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polyelectrolytes; electrostatic interactions; phase transitions; colloidal stability; surface forces; Monte Carlo simulation; free energy evaluation; polyampholytes; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. LÄS MER

  3. 2. Modelling the Variability of Bending Strength in Structural Timber - Length and Load Configuration Effects

    Författare :Tord Isaksson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; code; reliability-based design; Weibull; test standard; load configuration effect; length effect; weak section; machine grading; visual grading; variability; Structural timber; bending strength; simulation; monte carlo simulation.; Building construction; Byggnadsteknik;

    Sammanfattning : The load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber.
