1. 1. 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

3. 2. Efficient FE Modeling of Large Casted Parts

   University essay from KTH/Maskinkonstruktion

   Author : Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
   Keywords : FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

   Abstract : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. READ MORE

4. 3. Modelling of a Glued Bolt Joint in Finite Element

   University essay from KTH/Hållfasthetslära

   Keywords : Solid Mechanics; finite element method; adhesive; bolt; hybrid joint; Hållfasthetslära; finita element metoden; lim; skurv; hybrid förband;

   Abstract : This report presents a master thesis project at KTH at the school of Engineering Science. The project is done in collaboration with ABB Robotics, a company who develops industrial robots. A robot consists of several parts and the last structural part is the wrist. READ MORE

5. 4. Modulation of the optical properties of quantum dots by surface acoustic waves

   University essay from KTH/Tillämpad fysik

   Author : Tanguy Schetelat; [2023]
   Keywords : Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

   Abstract : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. READ MORE

6. 5. 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
