  1. 1. A Differentiable Approach to Stochastic Differential Equations : the Smoluchowski Limit Revisited

    University dissertation from Växjö, Kalmar : Linnaeus University Press

    Author : Haidar Al-Talibi; Linnéuniversitetet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; α-stable Lévy noise; Fractional Brownian motion; Girsanov theorem; Mean-field model; Nonlinear stochastic oscillator; Ornstein-Uhlenbeck process; Scaling limit; Second order Itô equation; Time change.; Matematik; Mathematics;

    Abstract : In this thesis we generalize results by Smoluchowski [43], Chandrasekhar[6], Kramers, and Nelson [30]. Their aim is to construct Brownian motion as a limit of stochastic processes with differentiable sample paths by exploiting a scaling limit which is a particular type of averaging studied by Papanicolao [35].

  2. 2. Orientation of elongated, macro and nano-sized particles in macroscopic flows

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Karl Håkansson; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Orientation; fibre; fibril; turbulent channel flow; particle streaks; flow focusing; cellulose nanofibrils; extensional flow; Smoluchowski; rotary diffusion;

    Abstract : Non-spherical particles are present all around us, in biological, industrial and environmental processes. Making predictions of their impact on us and systems in our vicinity can make life better for everyone here on earth. READ MORE

  5. 5. Numerical approaches to droplet growth in atmospheric turbulence

    University dissertation from Stockholm University

    Author : Xiang-Yu Li; Stockholms universitet.; Stockholms universitet.; [2016]

    Abstract : The bottleneck problem of cloud droplet growth is one of the most challengingproblems in cloud physics. Cloud droplet growth is neither dominated by con-densation nor gravitational collision in the size range of 15–40 μm in radius.Turbulence-generated collision has been thought to be the mechanism to bridgethe size gap, i.e. READ MORE
