1. Safeguarding from surgical site infections : A mutual responsibility between the patient, caregiver and the perioperative healthcare leaders
Sammanfattning : Aim: The overall aim of this thesis is to describe and explore preventive measuresand risks for surgical site infections.Methods: Study I, a registry based and observational design study, includes 35 056cases analysed for risks for reoperation caused by periprosthetic joint infection afterelective total hip arthroplasty.

2. Surface Wave Testing of Pavements
Sammanfattning : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. LÄS MER
3. Optical Turbulence Characterization for Ground-Based Astronomy
Sammanfattning : The optical turbulence, which creates perturbations of the wavefronts coming from the stars, is caused by small-scale fluctuations in the index of refraction of the atmosphere and is a problem for astronomers because it limits the maximum resolution of the ground-based telescopes. One way of identifying the best sites to build astronomical observatories, where the influence of the optical turbulence is as small as possible, is to use the standard meteorological parameters to get a first idea of the potential of a site.

4. Track circuits’ robustness : Modeling, measurement and simulation
Sammanfattning : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. LÄS MER
5. Seismic quiescence patterns and earthquake prediction research : Testing hypotheses for Greece and China
Sammanfattning : The main aim of this investigation is to evaluate the most well known hypotheses and models in earthquake prediction research. For this reason we investigate the "localized" seismic quiescence hypothesis using the Z value griding method as well as the recently introduced Seismolap hypothesis of "extended" seismic quiescence.
