Experimental investigation of near-field effects on the SASW dispersion curve
… using the Spectral-Analysis-of-Surface-Waves (SASW) method was used in this thesis research. SASW tests performed at two stages in the construction of a deep, 90-ft thick backfill were studied. The V[subscript s] profiles were normally dispersive, with a substantial increase in the velocity of …

Improving resolution of stiff layers in soil profiles through multi-step inversion of Sasw data
Stiff, cemented layers commonly encountered in desert soil profiles significantly affect the soil load capacity and load distribution pattern. The purpose of this research is to develop algorithms for detecting stiff layers through inversion of seismic surface wave data to generate one-dimensional …

Multistation Methods for Geotechnical Characterization using Surface Waves
… for site characterization, of whose the SASW (Spectral Analysis of Surface Waves) method is by far the most well-known in geotechnical engineering. The research has been mainly focused on the application of multistation methods, compared with the classical two-station approach typical of …

Development of the Spectral-Analysis-of-Body-Waves (SABW) method for downhole seismic testing with boreholes or penetrometers
… are the Spectral-Analysis-of-Surface-Waves (SASW) and Multi-Channel-Analysis-of-Surface-Waves (MASW) methods. In this research, an automated procedure for calculating body wave velocities that is based on frequency-domain analysis is presented. The basis for and an automated procedure to …

"Social work" and missionary work as part of the power game
This thesis discusses "social work" as part of missionary work during Hans Egede´s mission in Greenland (1721-1736) and the starting period of the Norwegian Saami mission (1888-1900). The discussion is focused by connecting it to Habermas´s discussion of "The structural transformation of the …

De hjälper oss till rätta : normaliseringsarbete, självbestämmande och människor med psykisk utvecklingsstörning
For people with learning disabilities care in institutions has been replaced by a life in community settings e.g. group homes, where a number of persons (4-5) are living with staff support. My case-studies cover three elderly and three more lately produced such units as well as a ward in a nursing …
