  1. 1. Evaporation Duct Modelling for a Wave-Propagation Simulator

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Oscar Eklund; [2022]
    Keywords : evaporation; duct; height; monin; obukhov; mos; surface; layer; ssft; byc; pj; businger; dyer; beljaars; holtslag; cheng; brutsaert; sheba;

    Abstract : Long-range communication proves to be a challenge due to the Earth’s curvature, since electromagnetic waves propagate away from the Earth’s surface in a free atmosphere. A possible solution to beyond line-of-sight communication is the atmospheric phenomenon known as the evaporation duct. READ MORE

  3. 2. Particle focusing and separation in curved microchannels using elasto-inertial microfluidics

    University essay from KTH/Tillämpad fysik

    Author : Belinda Bergström; [2022]
    Keywords : Elasto-inertial microfluidics; particle focusing; particle separation; nanobiotechnology; Elastisk tröghetsmikrofluidik; partikelfokusering; partikelseparation; nanobioteknologi;

    Abstract : The passive particle separation method of elasto-inertial microfluidics have greatpotential in the field of physics, biology and chemistry. The objective of thisdegree project was to understand particle behavior in curved microchannels fornon-Newtonian fluids. READ MORE

  4. 3. Matter-streams as sources of the Kerr metric

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Julian Boy; [2022]
    Keywords : General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

    Abstract : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. READ MORE

  5. 4. An Empirical Study on the Generation of Linear Regions in ReLU Networks : Exploring the Relationship Between Data Topology and Network Complexity in Discriminative Modeling

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

    Author : Petter Eriksson; [2022]
    Keywords : Neural networks; Linear regions; Activation patterns; Piecewise linear activation functions; Data; Curvature; Neurala nätverk; Linjära regioner; Styckvis linjära aktiveringsfunktioner; Data; Krökning;

    Abstract : The far-reaching successes of deep neural networks in a wide variety of learning tasks have prompted research on how model properties account for high network performance. For a specific class of models whose activation functions are piecewise linear, one such property of interest is the number of linear regions that the network generates. READ MORE

  6. 5. Spherically Symmetric Gravitational Collapse

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Lucas Bring; [2021]
    Keywords : gravitational collapse; gravitation; general relativity; black hole; Schwarzschild coordinates; Gullstrand-Painleve coordinates; Friedmann-Robertson-Walker metric; finite-time collapse; Physics and Astronomy;

    Abstract : This thesis presents a derivation of the equation of motion of particles in a dust star, as it undergoes collapse. This is done by finding exact solutions to the Einstein field equations. We follow the original work by Oppenheimer and Snyder, starting from the general spherically symmetric metric in comoving coordinates. READ MORE
