  1. 1. Essays on Distance Based (Non-Euclidean) Tests for Spatial Clustering in Inhomogeneous Populations : Adjusting for the Inhomogeneity through the Distance Used

    Författare :Ulla Romild; Johan Lyhagen; Anders Ågren; Jack Cuzick; Uppsala universitet; []
    Nyckelord :Statistics; Clustering; Spatial Point Pattern; Inhomogeneous Density; Statistik;

    Sammanfattning : This thesis consits of four papers dealing with distance based (non-Euclidean) tests for spatial clustering in inhomogeneous populations. The density adjusted distance (DAD), which considers the underlying density, is defined in the first paper. LÄS MER

  4. 3. Expecting Happy Women, Not Detecting the Angry Ones : Detection and Perceived Intensity of Facial Anger, Happiness, and Emotionality

    Författare :Tonya S. Pixton; Åke Hellström; Maria Larsson; James A. Russell; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Signal Detection Perception ; Happiness; Anger; Face Perception; Facial Expressions; Superiority Effects; Gender Differences; Response Bias; Scaling; Euclidean Distance; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Faces provide cues for judgments regarding the emotional state of individuals. Using signal-detection methodology and a standardized stimulus set, the overall aim of the present dissertation was to investigate the detection of emotional facial expressions (i.e., angry and happy faces) with neutral expressions as the nontarget stimuli.

  5. 4. On Spectrally Efficient Continuous Phase Modulation

    Författare :Tommy Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adjacent channel interference; additive white Gaussian noise {AWGN} ; convolutional codes; minimum Euclidean distance; continuous phase modulation CPM ; bandwidth efficiency; co-channel interference; reduced complexity detectors; optimized phase pulses.;

    Sammanfattning : Spectrally efficient partial response continuous phase modulation (CPM)for wireless links is considered. Continuous phase modulation defines constantenvelope phase codes, which are advantageous when using non-linear amplifiers. LÄS MER

  7. 5. Image processing on optimal volume sampling lattices : Thinking outside the box

    Författare :Elisabeth Schold Linnér; Robin Strand; Ewert Bengtsson; Alexandre Falcão; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BCC; FCC; aliasing; distance transform; segmentation; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : This thesis summarizes a series of studies of how image quality is affected by the choice of sampling pattern in 3D. Our comparison includes the Cartesian cubic (CC) lattice, the body-centered cubic (BCC) lattice, and the face-centered cubic (FCC) lattice. LÄS MER
