  1. 11. Application of the SASW-technique in geotechnical in-situ testing

    University dissertation from Mats Svensson, Geotechnology, Box 118, 221 00 LUND

    Author : Mats Svensson; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; Spectral Analysis of Surface Waves; shear modulus; SASW; multichannel; inversion; Gmax; teknisk geografi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; geographical and geological engineering; Hydrogeology; Civil engineering; hydraulic engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : With the main aim to test the applicability of the surface wave seismic technique Spectral Analysis of Surface Waves (SASW), used for determination of the shear stiffness (shear modulus - Gmax), four areas of applications have been studied. The four areas have been sites with natural geological conditions, sites where non destructive testing is necessary, pavement testing and multichannel testing. READ MORE

  2. 12. Rut Depth Prediction on Flexible Pavements - Calibration and Validation of Incremental-Recursive Models

    University dissertation from Department of Technology and Society, Lund University

    Author : Sven Agardh; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; offshore technology; Civil engineering; hydraulic engineering; Teknik; Technological sciences; PM-system; deterioration models; rutting; pavement design; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : In later years the development of pavement design has gone towards more and more analytically based methods. Future design will probably be based on incremental deterioration models. The objective is to evaluate different types of rut depth prediction models for an incremental design process. READ MORE

    Abstract : Wave energy is a renewable energy source with a large potential to contribute to the world's electricity production. There exist several technologies on how to convert the energy in the ocean waves into electric energy. The wave energy converter (WEC) presented in this thesis is based on a linear synchronous generator. READ MORE

  5. 15. Wave Loads and Peak Forces on Moored Wave Energy Devices in Tsunamis and Extreme Waves

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Linnea Sjökvist; Uppsala universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OpenFOAM; CFD; Wave power; Tsunami waves; Extreme waves; Offshore; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Surface gravity waves carry enormous amounts of energy over our oceans, and if their energy could be harvested to generate electricity, it could make a significant contribution to the worlds power demand. But the survivability of wave energy devices in harsh operating conditions has proven challenging, and for wave energy to be a possibility, peak forces during storms and extreme waves must be studied and the devices behaviour understood.
