1. A Quantitative Microbial Risk Assessment Associated with Cross-Connections in the Drinking Water Network in Combination with Hydraulic Modeling
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Drinking water companies have the technology and responsibility to deliver safe and high-quality drinking water to the water distribution systems network (WDN). However, many events within the WDN, such as cross-connections and backflow, might degrade water quality and pose public health risks to consumers. LÄS MER
2. Online Parameter Estimation of a Six- Phase Machine for Marine Application
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In the recent decades, an increased interest into multiphase machines has developed due to certain beneficial properties they have over the standard three- phase machines. Proper modelling of a multiphase machine allows access to higher degrees of freedom given by the ability to control higher order harmonic frames. LÄS MER
3. En undersökning av effekten av on-site-faktorer vid sökmotoroptimering
Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : The significance of search engine optimization is clearly highlighted sin- ce over 90 % of internet usage starts with a search engine according to contemporary studies, whilst the internet also has contributed to increa- sed competition between companies operating from different geographic markets. Guidelines from search engines and theory from studies descri- be several internal influencing factors, on-site factors, but ambiguous in the studies is how much these factors affect the ranking.

4. Attitude and Orbit Control During Deorbit of Tethered Space Debris
Master-uppsats, KTH/Farkost och flygSammanfattning : Due to the unsustainable space debris environment in Low Earth Orbit, debris objects must be removed to ensure future safe satellite operations. One proposed concept for deorbiting larger space debris objects, such as decommissioned satellites or spent upper rocket stages, is to use a chaser spacecraft connected to the debris object by an elastic tether, but the required technology is immature and there is a lack of flight experience.

5. Modeling and Control of Friction Stir Welding in 5 cm thick Copper Canisters
Master-uppsats, Reglerteknik; Tekniska högskolanSammanfattning : Friction stir welding has become a popular forging technique used in many applications. The Swedish Nuclear Fuel and Waste Management Company (SKB) evaluates this method to seal the 5 cm thick copper canisters that will contain the spent nuclear fuel. LÄS MER
