  1. 1. Finite element density functional description of linear molecules

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Malin Nygren; [2024]
    Keywords : ;

    Abstract : This report describes a project performed at Linnaeus University with the task of solving the Schrodinger equation for electrons in homonuclear diatomic molecules, using the finite element method in Python. The Schrodinger equation is solved for the hydrogen atom, nitrogen atom, hydrogen molecule and nitrogen molecule using a finite element method. READ MORE

  3. 2. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

    University essay from KTH/Matematik (Avd.)

    Author : Bill Claesson; [2023]
    Keywords : ;

    Abstract : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. READ MORE

  4. 3. Plastic deformation of hot riveted joints acting in shear

    University essay from KTH/Bro- och stålbyggnad

    Author : Victor Gard; [2023]
    Keywords : ;

    Abstract : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. READ MORE

  5. 4. Implementation and study of boundary integral operators related to PDE:s in the plane

    University essay from Lunds universitet/Matematik LTH

    Author : Erik Andersson; [2023]
    Keywords : Boundary integral equation; Singular integral operator; Product integration; Close evaluation; Numerical integration; MATLAB; Mathematics and Statistics;

    Abstract : The method of solving boundary value problems of partial differential equations numerically by first reformulating the problem as a boundary integral equation has many advantages over other methods, but also some unique difficulties. Some of these difficulties stem from problems in evaluating singular or nearly singular integral operators, and solving these difficulties is an active field of research. READ MORE

  6. 5. Numerical calculations ofgradients using random walkmethodswith applications to electriccurrents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Oscar Broliden; [2023]
    Keywords : ;

    Abstract : We have studied examples of random walk methods (RWM) applied to electric problems, solving the Laplace equation. Especially we did calculationswith digital pictures as domains, and evaluated an improvement in calculation speed for the random walk method. READ MORE
