  1. 1. Probabilistic Modelling of Hearing : Speech Recognition and Optimal Audiometry

    Författare :Svante Stadler; Arne Leijon; Stefan Stenfelt; KTH; []
    Nyckelord :auditory models; probabilistic modelling; speech modelling; human speech recognition; hearing aids; cochlear implants; psychoacoustics; diagnostic methods; optimal experiments; audiometry;

    Sammanfattning : Hearing loss afflicts as many as 10\% of our population.Fortunately, technologies designed to alleviate the effects ofhearing loss are improving rapidly, including cochlear implantsand the increasing computing power of digital hearing aids. Thisthesis focuses on theoretically sound methods for improvinghearing aid technology. LÄS MER

  3. 2. Probabilistic treatment planning based on dose coverage : How to quantify and minimize the effects of geometric uncertainties in radiotherapy

    Författare :David Tilly; Anders Ahnesjö; Erik Grusell; Uwe Oelfke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; treatment simulation; probabilistic planning; dose calculation; probabilistic optimization; statistical shape model; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Traditionally, uncertainties are handled by expanding the irradiated volume to ensure target dose coverage to a certain probability. The uncertainties arise from e.g. the uncertainty in positioning of the patient at every fraction, organ motion and in defining the region of interests on the acquired images. LÄS MER

  4. 3. Draw control strategy for sublevel caving mines : A probabilistic approach

    Författare :Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Matthias Wimmer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control; sublevel caving; probability models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. LÄS MER

  5. 4. Integrated and Probabilistic Risk Analysis of Drinking Water Systems

    Författare :Andreas Lindhe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water safety plan; customer minutes lost; probabilistic; fault tree analysis; risk analysis; risk; integrated; drinking water system; hazard; uncertainty;

    Sammanfattning : Drinking water supply is an essential public function but is at the same time exposed to risks. Since a totally risk-free society is not attainable, risks need to be managed efficiently to achieve an acceptable level of risk. LÄS MER

  7. 5. Forecasting of Icing Related Wind Energy Production Losses : Probabilistic and Machine Learning Approaches

    Författare :Jennie Molinder; Anna Sjöblom; Heiner Körnich; Hans Bergström; Erik Nilsson; Sue Ellen Haupt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wind energy; Icing on wind turbines; Machine learning; Probabilistic forecasting; Meteorologi; Meteorology;

    Sammanfattning : Icing on wind turbine blades causes significant production losses for wind energy in cold climate. Next-day forecasts of these production losses are crucial for the power balance in the electrical grid and for the trading process, but they are uncertain due to lack of understanding of, and simplifications, in the modelling chain.
