  1. 1. Towards Precise Localisation : Subsample Methods, Efficient Estimation and Merging of Maps

    Författare :Gabrielle Flood; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; localisation; map merging; subsample; stochastic analysis; time-difference-of-arrival;

    Sammanfattning : Over the last couple of years audio and radio sensors have become cheaper and more common in our everyday life. Such sensors can be used to form a network, from which one can obtain distance measures by correlating the different received signals. LÄS MER

  3. 2. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations

    Författare :Gabrielle Flood; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time of arrival; TOA; Time-difference of arrival; TDOA; Subsample methods; Uncertainty measure; Constant offset; RANSAC; Map merging; Map fusion; Change detection; Collaborative SLAM; Structure from motion; SfM; SLAM; Mapping; Localisation; Registration; Sparse maps; Point clouds;

    Sammanfattning : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. LÄS MER

  4. 3. Temporomandibular disorders among Sami women : perspectives based on an epidemiological survey with mixed methods

    Författare :Christina Storm Mienna; Anders Wänman; Martti Helkimo; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epidemiology; gender; headache; indigenous; pain; qualitative; quality of life; temporomandibular; odontologi; Odontology;

    Sammanfattning : Introduction The aim of the research project was to examine prevalence, co-morbidity, and impact on daily life of pain and dysfunction in the jaw-face, head, and neck-shoulder regions among adult Sami women in northern Sweden. The aim of the qualitative part of the study was to explore, thoughts, experiences, and beliefs regarding temporomandibular disorders (TMD) among Sami women with and without TMD, to gain insights into their health care experiences.

  5. 4. Optimal Subsampling Designs Under Measurement Constraints

    Författare :Henrik Imberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inverse probability weighting; unequal probability sampling; optimal design; active sampling; M-estimation;

    Sammanfattning : We consider the problem of optimal subsample selection in an experiment setting where observing, or utilising, the full dataset for statistical analysis is practically unfeasible. This may be due to, e.g., computational, economic, or even ethical cost-constraints. LÄS MER

  7. 5. Bayesian Phylogenetic Inference

    Författare :Sebastian Höhna; Tom Britton; Fredrik Ronquist; Lars Arvestad; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we consider two very different topics in Bayesian phylogenetic inference. The first paper, "Inferring speciation and extinction rates under different sampling schemes" by Sebastian Höhna, Tanja Stadler, Fredrik Ronquist and Tom Britton, focuses on estimating the rates of speciation and extinction of species when only a subsample of the present day species is available.
