  2. 1. Vocal Expression of Emotion : Discrete-emotions and Dimensional Accounts

    Author : Petri Laukka; Patrik N. Juslin; Erik Börjesson; Roddy Cowie; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; speech; emotion; vocal expression; emotion dimensions; acoustic cues; categorical perception; nonverbal communication; speech synthesis; cross-cultural communication; decoding accuracy; emotion intensity; meta-analysis; discrete emotions; Psykologi; Psychology; Psykologi;

    Abstract : This thesis investigated whether vocal emotion expressions are conveyed as discrete emotions or as continuous dimensions. Study I consisted of a meta-analysis of decoding accuracy of discrete emotions (anger, fear, happiness, love-tenderness, sadness) within and across cultures. READ MORE

  4. 2. CT colonography. Technique, diagnostic accuracy and patient acceptance

    Author : Maria H Svensson (Reutersköld); Göteborgs universitet; []
    Keywords : Colon; Rectum; Computed tomography; Three-dimensional imaging; Colorectal neoplasms; Colonic polyps; Colonoscopy; Acceptance testing; Incidental findings; Diagnostic accuracy;

    Abstract : The aim was to evaluate diagnostic potential, technical performance, and patient acceptance of CT colonography when used for detection of colorectal polyps and cancer in symptomatic patients with a high risk of colorectal neoplasia.Methods: After bowel preparation, 111 symptomatic patients underwent CT colonography followed by conventional colonoscopy.

  5. 3. Hybrid Grid Generation for Viscous Flow Computations Around Complex Geometries

    Author : Lars Tysell; Laszlo Fuchs; Nigel P. Weatherill; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; grid generation; unstructured grids; hybrid grids; surface grids; three-dimensional grids; adaptive grids; moving grids; grid quality; accuracy; Fluid mechanics; Strömningsmekanik;

    Abstract : A set of algorithms building a program package for the generation of twoandthree-dimensional unstructured/hybrid grids around complex geometrieshas been developed. The unstructured part of the grid generator is based on the advancing frontalgorithm. READ MORE

  6. 4. Classification models for high-dimensional data with sparsity patterns

    Author : Annika Tillander; Tatjana Pavlenko; Daniel Thorburn; Patrik Ryden; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-dimensionality; supervised classification; classification accuracy; sparse; block-diagonal covariance structure; graphical Lasso; separation strength; discretization; Statistics; statistik;

    Abstract : Today's high-throughput data collection devices, e.g. spectrometers and gene chips, create information in abundance. However, this poses serious statistical challenges, as the number of features is usually much larger than the number of observed units. READ MORE

  7. 5. Three-Dimensional Load-Deformation Relationships of Arbitrarily Loaded Coiled Springs

    Author : Lars Lindkvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extended stiffness model; helical spring; non-linear deformation; stiffness matrix; coiled spring; arbitrary load; large deformation; three-dimensional;

    Abstract : This paper reports the development of a computer based tool that can be used to predict the three-dimensional load-deformation relationships of arbitrarily loaded coiled springs. The non-linear deformation of the spring is calculated by dividing the spring into small elements for which the load-deformation relationships can be considered to be linear. READ MORE
