  1. 1. The Chemistry of Plutonium Solubility

    Författare :Hans Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sorption; colloids; solubility; modeling; oxidation states; plutonium; hydrolysis; actinides;

    Sammanfattning : When designing a repository for spent nuclear fuel it is necessary to assess the possibility that radionuclides will be transported from the repository by groundwater. A limiting factor for such transport is the solubility of any given radionuclide. LÄS MER

  3. 2. Subject-specific musculoskeletal modeling of the lower extremities in persons with unilateral cerebral palsy

    Författare :Olesya Klets; Elena Gutierrez-Farewik; Sven Kleiven; KTH; []
    Nyckelord :cerebral palsy; moment arm; muscle length; hemiplegic; MRI; subject-specific; musculoskeletal modeling; lower extremities; muscle volume; Mechanical engineering; Maskinteknik;

    Sammanfattning : The computational musculoskeletal models that are used to study muscle moment-generating capacities of persons with movement disorders and planning treatment options must be accurate, and take into account the inter-individual variability of musculoskeletal geometry. In Paper I the methods of creating the subject-specific musculoskeletal model of the lower extremities from magnetic resonance images (MRIs) were developed. LÄS MER

  4. 3. Mathematical modeling of the human smooth pursuit system

    Författare :Daniel Jansson; Alexander Medvedev; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This licentiate thesis concerns mathematical modeling and identification of the the human smooth pursuit system (SPS) and the application of the models to motor symptom quantification in Parkinson's disease (PD).The SPS is a complex neuromuscular system governing smooth pursuit eye movements (SPEM), and the task is to keep a moving target in the visual field.

  5. 4. Retarded sorption in wood : experimental study, analyses and modeling

    Författare :Håkan Håkansson; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; transient; non-linear model; swelling-shrinkage; latent heat effect; history-dependent sorption; anomalous sorption; non-Fickian; retarded sorption; measurements; moisture; wood; Byggnadsteknik;

    Sammanfattning : Models of moisture flow processes in wood are normally based on a Fickian approach. In many instances, there are considerable discrepancies between modelling and experimental results. It is shown in this thesis that a major cause for these discrepancies is a so-called retarded sorption which is not accounted for in conventional theories. LÄS MER

  7. 5. Information Integration in Perception and Cognition : Exploring the Perception-Cognition Gap

    Författare :Elina Stengård; Ronald van den Berg; Adam Sanborn; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Perception; Cognition; Information integration; Judgment; Computational modeling; Bayesian inference; Psychology; Psykologi;

    Sammanfattning : Much research in both perceptual inference and cognitive inference has focused on how well human performance fares against what is considered the most optimal or rational thing to do. The verdict, however, differs between the fields. LÄS MER
