1. Service life of repaired concrete bridge decks
Sammanfattning : Pre-mature deterioration of reinforced concrete causesproblems world-wide and the search for reliable cost effectiveand environmental friendly repairs is intense. The service lifeof the repaired structure is important in order to establishthe annual cost and environmental impact for differentalternatives. LÄS MER
2. Digital stereomicroscopy for measurements of deformations, velocity fields and microstructural changes of paper
Sammanfattning : There is a strongly increasing request of measuring systems for mechanical properties studies, for example in the paper industry. Paper research is today not only concentrated to flock studies, weight and quality controls of the paper but also focussing of mechanical behaviours in the fibre scale. LÄS MER
3. Computational weld mechanics - Increased accuracy in fatigue assessment, distortion and residual stress analysis
Sammanfattning : This thesis work is concerned with the mechanical response of welded steel structures, which are distortions, residual stresses, and fatigue. The accuracy of fatigue assessment, distortion and residual stress analysis using Computational weld mechanics (CWM) is focused. LÄS MER
4. The (γ,p) reaction in 16O and 18O at Eγ=50 - 70 MeV
Sammanfattning : A measurement of the reactions 16O(γ,p)15N and 18O(γ,p)17N have been made with tagged photons in the energy range Eγ ≈ 50 – 70 MeV. The protons have been detected in ΔE-E telescopes with silicon strip detectors as ΔE detectors and HPGe crystals as E detectors. LÄS MER
5. Advanced III-Nitride Technology for mm-Wave Applications
Sammanfattning : Within wireless communication, there is a continuously growing need for more bandwidth due to an increasing number of users and data intense services. The development within sensor systems such as radars, is largely driven by the need for increased detection range and robustness. LÄS MER
