1. Mapping an Auditory Scene Using Eye Tracking Glasses
Master-uppsats, Linköpings universitet/ReglerteknikSammanfattning : The cocktail party problem introduced in 1953 describes the ability to focus auditory attention in a noisy environment epitomised by a cocktail party. An individual with normal hearing uses several cues to unmask talkers of interest, such cues often lacks for people with hearing loss. LÄS MER
2. Watershed delineation for runoff estimations to culverts in the Swedish road network : a comparison between two GIS based hydrological modelling methods and a manually delineated watershed
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The anticipated climate changes are predicted to alter the precipitation patterns in Sweden. Increased episodes of intense short-duration rainfall and higher intensities of day long-duration rainfall are expected. Road sections are often a target of flooding, causing impassable roads, due to the lack of capacity of drainage systems. LÄS MER
3. Urban flood modelling : a GIS based approach in Lomma, Skåne region
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Urbanization triggers flooding because it replaces pervious land surfaces with impervious surfaces that have less capacity to infiltrate and store water into the ground. Detailed analysis and modelling of flooding in urban areas can be performed with GIS-based distributed hydrological models. LÄS MER
4. A dynamic and spatially distributed rainfall runoff model - Developing a model for overland flow in GIS, based on a multiple flow direction algorithm
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : Climate change is expected to cause 20-25% heavier rainfall in Sweden which, in combination with the ongoing urbanization, increases the probability of flooding in urban areas. These floods may cause large infrastructural damage and economical costs. LÄS MER
5. Modelling near ground wind speed in urban environments using high-resolution digital surface models and statistical methods
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Wind is a complex phenomenon and a critical factor in assessing climatic conditions and pedestrian comfort within cities. This master’s thesis attempts to quantify and model the relationship between near ground wind speed and urban geometry using two-dimensional raster data and variable selection methods based on Multiple Linear Regression.
