1. 11. Protons in In-doped BaZrO3: incorporation, distribution and local environments

   Författare :Laura Mazzei; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrogen dynamics; hydrogen depth profiling; vibrational spectroscopy; neutron scattering; thin films; perovskites; Proton conductors;

   Sammanfattning : Acceptor doped proton conducting oxides are currently of large interest for their potential application as electrolyte materials in the future generation of solid oxide fuel cells. However, their proton conductivities are still lower than the target conductivity required for practical applications. LÄS MER

3. 12. A Comparative Investigation of Gear Performance BetweenWrought and Sintered Powder Metallurgical Steel : Utilizing In-situ Surface Profile Measurements to Investigate theInitiation and Evolution of Micropitting and Pitting Damage

   Författare :Edwin Bergstedt; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gear testing; Micropitting; Pitting; Efficiency; Surface transformation; Kugghjulstestning; Micropitting; Pitting; Effektivitetsmätning; Yttransformationer; Machine Design; Maskinkonstruktion;

   Sammanfattning : Vehicle electrification is a strong trend that introduces new challenges, such as increased input speed of the transmission and increased power density. Alsothe noise emittance of the gearbox is of increasing importance, as the sound of the gearbox is no longer masked by the internal combustion engine. LÄS MER

4. 13. Time-lapse Analysis of Borehole and Surface Seismic Data, and Reservoir Characterization of the Ketzin CO2 Storage Site, Germany

   Författare :Can Yang; Christopher Juhlin; Rob Arts; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amplitude anomaly; AVO analysis; Carbon dioxide storage; Moving source profile survey; Reflection coefficient; Reservoir characterization; Static correction; Time-lapse analysis; Geophysics with specialization in Seismology; Geofysik med inriktning mot seismologi;

   Sammanfattning : The CO2SINK (and CO2MAN) project is the first onshore CO2 storage project in Europe. The research site is located near the town of Ketzin, close to Potsdam in Germany. Injection started in June 2008, with a planned injection target of 100,000 tonnes of CO2. LÄS MER

5. 14. Groundwater vulnerability assessment using process-based models

   Författare :Riitta Lindström; Roger Thunvik; Pertti Vakkilainen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Database; Groundwater vulnerability; Hydrogeological environment; Process-based models; Penetration depth; Turnover time; Miljöteknik; Environmental engineering; Miljöteknik;

   Sammanfattning : The focus of this thesis is on groundwater vulnerability assessment by process-based simulation models and data acquisition for these assessments. A modelling system for intrinsic groundwater vulnerability assessment in water supply areas was developed, consisting of flow- and transport models for the unsaturated zone and the groundwater zone, coupled to a geographical informa-tion system.

7. 15. On the Application of Surface Wave Surveys for Seismic Site Response Evaluation

   Författare :Edwin Obando; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface wave; MASW; seismic site response; ground motion; seismic transfer functions; shear wave velocity; site amplification; walk-away; near-field effect; dispersion curve.;

   Sammanfattning : In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. LÄS MER
