  1. 1. Mapping an Auditory Scene Using Eye Tracking Glasses

    University essay from Linköpings universitet/Reglerteknik

    Author : Alfred Fredriksson; Joakim Wallin; [2020]
    Keywords : Sensor Fusion;

    Abstract : 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. READ MORE

  2. 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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Iris Behrens; [2017]
    Keywords : GIS; hydrological modelling; watershed: single flow direction algorithm; multiple flow direction algorithm; climate change adaption; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  3. 3. Urban flood modelling : a GIS based approach in Lomma, Skåne region

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Michael Araya Ghebremariam; [2017]
    Keywords : Physical Geography and Ecosystem analysis; Digital Elevation Model; Single flow direction algorithm; Deterministic eight-node D8 algorithm; Multiple flow direction algorithm; Triangular Form Based Multiple Flow algorithm TFM ; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  4. 4. A dynamic and spatially distributed rainfall runoff model - Developing a model for overland flow in GIS, based on a multiple flow direction algorithm

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Hampus Nilsson; [2017]
    Keywords : flood modelling; GIS; TFM; surface runoff; multiple flow; flow routing; Technology and Engineering;

    Abstract : 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. READ MORE

  5. 5. Modelling near ground wind speed in urban environments using high-resolution digital surface models and statistical methods

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lars Johansson; [2012]
    Keywords : Geographic Information System; spatial variability; GIS; digital surface model; wind speed; urban geometry; geomatics; geography; urban climate; physical geography; geografi; naturgeografi; geomatik; stadsklimat; bebyggelsegeometri; vindhastighet; digital höjdmodell; rumslig variation; geografiska informationssystem; Earth and Environmental Sciences;

    Abstract : 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.
