  1. 11. The effect of taper on pile shaft bearing capacity : Finite element analysis of a tapered wooden pile in sulfate soil

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jonathan Lindström; [2023]
    Keywords : Pile; taper; timber piles; wooden piles; sulphide soil; sulfate soil; tapered piles;

    Abstract : he usage of piles, especially wooden piles, have been going on for thousands of years in construction and foundation reinforcements. Sometimes this was done temporary like the Romans who used wooden piles to construct bridges in Britain, or more permanently like the piles upon which the floating city of Venice stands. READ MORE

  3. 12. 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

  4. 13. 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

  5. 14. Effective shear stiffness of cross-laminated timber : Comparison between numerical and analytical approaches

    University essay from KTH/Bro- och stålbyggnad

    Author : Therese Badrous; Las Muradi; [2023]
    Keywords : ;

    Abstract : The increasing importance of sustainability has led to a focus on smart solutions for energy consumption and materials. Cross-laminated timber (CLT) has gained attention as a sustainable alternative in construction, offering high strength, stiffness, and dimensional stability. READ MORE

  6. 15. Gradients of the Poisson Equation using a Stochastic Method

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

    Author : Emil Gestsson; [2023]
    Keywords : ;

    Abstract : In this report, a recently discovered numerical method has been tested and shown to be viable. The method aims to calculate the gradient of the solution of a bounded Poisson equation, specifically: 1/2 ∇² φ + f |G = 0,   φ(x) |∂G  = 0, (0.1) where G is some open domain. READ MORE
