  1. 1. Exploring Probabilistic Reasoning : A Study of How Students Contextualise Compound Chance Encounters in Explorative Settings

    Författare :Per Nilsson; Inger Wistedt; Lennart Hellström; Dave Pratt; Växjö universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Probabilistic reasoning; randomness; compound chance encounters; contextualisation; differentiation; elaborative variation.; MATHEMATICS; MATEMATIK; Matematikdidaktik; Mathematical Education; Mathematical Didactics;

    Sammanfattning : This thesis aims at exploring how probabilistic reasoning arises in explorative learning situations that are random in nature. The focus is especially on what learners with scant experience of formal theories of probability do and can do when dealing with compound random situations in which they are offered opportunities to integrate different probabilistic lines of reasoning.

  2. 2. 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. 3. 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 :NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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
