   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Elias Estensen; [2022]
   Keywords : Helmholtz; wave equation; acoustics; ocean acoustics; numerical analysis; computational science; finite differences; summation by parts; sbp; waveholtz; cylindrical coordinates; sediment layers; interface; super-grid; super grid; absorbing layer; Helmholtz; vågekvationen; akustik; undervattensakustik; numerisk analys; beräkningsvetenskap; finita differenser; summation by parts; sbp; cylindriska koordinater; waveholtz; sedimentskikt; interface; super-grid; absorberande lager;

   Abstract : In this report, we study how finite differences can be used to simulate acoustic wave propagation originating from a point source in the ocean using the Helmholtz equation. How to model sediment layers and the vast size of the ocean is studied in particular. READ MORE

3. 2. Investigation of the use of Laser Scanning for Deformation Monitoring

   University essay from KTH/Geodesi och geoinformatik

   Author : Hulumtaye Hulumtaye Kefyalew Yederulh; [2013]
   Keywords : Terrestrial laser scanner; Total station; Surface parameters; Surface modeling; Estimation of deformation;

   Abstract : The ability of fast and accurate acquiring of large 3D spatial data is the main benefit for consideration of a terrestrial laser scanner in deformation monitoring. The objective of this paper is to discuss this technique with support of practical experiments performed inside a laboratory. READ MORE
