  2. 11. Symmetry Filters Applied to Fingerprints : Representation, Feature extraction and Registration

    Author : Kenneth Nilsson; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fingerprint recognition; symmetry filters; orientation field; multiscale filtering; singular points; orientation radiograms; registration; multiexpert; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : A common framework for feature extraction in fingerprints is proposed by use of certain symmetries. The proposal includes representation, filters, and filtering techniques for common features including minutiae points, singular points and the ridge and valley patterns. READ MORE

  4. 12. Wild Landscapes : The Cultural Nature of Swedish National Parks

    Author : Tom Mels; Institutionen för kulturgeografi och ekonomisk geografi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; national park; landscape; space; reinvention; performance; representation; wilderness; Social geography; imagery; nature; Socialgeografi; Social and Economic Geography;

    Abstract : Since their emergence in the late 19th century, national park spaces have been perceived as articulations of untouched nature or wild landscape beyond society. Yet no understanding of national parks can do without the recognition that they exist in historical spaces created, institutionalised and prepared for them by cultural practices and modes of representation.

  5. 13. Satistical Modelling Of CO2 Exchange Between Land And Atmosphere : Using Stochastic Optimisation And Gaussian Markov Random Fields

    Author : Unn Dahlén; Spatio-Temporal Stochastic Modelling Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gaussiska Markovfält; Stokastisk optimering; CO2-flöden; Spatial statistik; Stochastic Optimisation; Gaussian Markov Random Fields; Atmospheric inverse modelling; Spatial statistics; Computational statistics;

    Abstract : This thesis focuses on the development and application of efficient mathematicaltools for estimating and modelling the exchange of carbon dioxide (CO2) between the Earth and its atmosphere; here referred to as the global CO2 surface flux.There are two main approaches for estimating the CO2 flux: Processed based(bottom-up) modelling and atmospheric inversion (top-down) modelling.

  6. 14. On computational methods for spatial mapping of the human proteome

    Author : Casper F. Winsnes; Emma Lundberg; Ida-Maria Sintorn; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial proteomics; Human Protein Atlas; Micronuclei; Citizen science; Biotechnology; Bioteknologi;

    Abstract : Proteins are complex molecules that are involved in almost every task in the body. In general, the role a protein fulfills is highly dependent on where in the cell it is located, its subcellular localization. READ MORE

  7. 15. Constituting performance : Case studies of performance auditing and performance reporting

    Author : Fredrik Svärdsten Nymans; Anders Grönlund; Bino Catasús; Andrea Mennicken; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Constituting performance; performance measurement; performance management; performance reporting; performance audit; performance standards; audit independence; accounting concepts; output; representation; government at a distance; social construction; företagsekonomi; Business Administration;

    Abstract : The aim of this thesis is to problematize how and under what conditions organizational performance is constituted in the practices of performance auditing and accounting. Organizational performance disclosure is a world-wide phenomenon for enabling accountability relationships in large organizations regardless of the societal sector they operate in. READ MORE
