1. Inverse Uncertainty Quantification for Sounding Rocket Dispersion
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : Sounding rocket impact points are subject to dispersion due to uncertainties in simulation model parameters and perturbations of the rocket trajectory during flight. Estimating the area of dispersion assumes that associated model uncertainties and magnitude of perturbations have already been inferred. LÄS MER
2. Implementing spatial variance in the rate of photolytic breakdown of NO2 in urban street canyons
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : In this study a module for calculating the solar exposure of individual fluid cells was developed to more accurately represent the effect of photolysis on the pollutant dispersion in an urban street canyon. The module was tested and validated on 12 different cases, each with a different geographical location, time of year and/or time of day. LÄS MER
3. Inverse Atmospheric Dispersion Modeling in Complex Geometries
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : In the event of a radioactive release in an urban environment the consequent response mustbe swift and precise. As soon as first responders have correct information, they can make anaccurate risk assessment. However, if the position, release rate and time of the radioactiverelease is unknown it is hard to know how the pollutant will spread. LÄS MER
4. Contamination analysis of the landfill Rösaberg inerta massor : Risk assessment and investigation of the contaminant distribution
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The dispersion of contaminants deriving from landfills poses a risk to the surrounding environment and human health. Old landfills are treated with extra precaution, due to their poorer construction, less stringent operation and lack information regarding the waste content. Vetlanda municipality has identified 48 old landfills. LÄS MER
5. Reducing waste with an optimized trimming model in production planning
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistikSammanfattning : In which ways can the process of trimming dispersion coated board products be optimized so as to reduce material waste and increase production efficiency? This is the question that this master thesis report seeks to answer. In paper production, alot of waste is generated when cutting production reels into customer reels. LÄS MER
