  1. 1. Revision ur ett revisorsperspektiv : en metodstudie

    Författare :Anna-Maria Jansson; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; revisorsperspektiv; referensramar; ”the Repertory Grid Technique”; principalkomponentanalys; “the Critical Incident Technique”; Business and economics; Ekonomi;

    Sammanfattning : Ett återkommande problem inom revisionsforskningen handlar om de svårigheter forskare ställs inför med avseende på att få tillgång till information från revisorer som baseras på verkliga händelser. Anledningar som förts fram till detta är att revisorer är bundna vid tystnadsplikt samt att det förefaller råda en ”kultur av tystnad” inom professionen. LÄS MER

  3. 2. On design of experiments in continuous processes

    Författare :Erik Vanhatalo; Geoffrey Vining; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Sammanfattning : Design of Experiments (DoE) includes powerful methods, such as factorial designs, to help maximize the information output from conducted experiments while minimizing the experimental work required for statistically significant results. The benefits of using DoE in industry are thoroughly described in the literature although the actual use of the methods in industry is far from being pervasive. LÄS MER

  4. 3. Applications of common principal components in multivariate and high-dimensional analysis

    Författare :Toni Duras; Thomas Holgersson; Tatjana Pavlenko; Jönköping University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of four papers, all exploring some aspect of common principal component analysis (CPCA), the generalization of PCA to multiple groups. The basic assumption of the CPC model is that the space spanned by the eigenvectors is identical across several groups, whereas eigenvalues associated with the eigenvectors can vary. LÄS MER

  5. 4. Electrochemical (bio-)sensors operating in human physiological fluids

    Författare :Carolin Psotta; Sergey Shleev; Magnus Falk; Evgeny Katz; Malmö universitet; []
    Nyckelord :biosensor; bacteria; enzyme; sensor; physiological fluid;

    Sammanfattning : This thesis is focused on developing electrochemical (bio-)sensors specifically designed to detect biomolecules and bacteria in human physiological fluids. A more comprehensive understanding of their performance can be obtained by exposing the sensors to real human physiological fluids. LÄS MER

  7. 5. Enhancing Short-Term Traffic Prediction for Large-Scale Transport Networks by Spatio-Temporal Clustering

    Författare :Matej Cebecauer; Erik Jenelius; Wilco Burghout; Francisco Camara Pereira; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; short-term prediction; clustering; spatio-temporal clustering; day-types; speed-flow relationship; large-scale; Transportsystem; Transport Systems;

    Sammanfattning : Congestion in large cities is responsible for extra travel time, noise, air pollution, CO2 emissions, and more. Transport is one of the main recognized contributors to global warming and climate change, which is getting increasing attention from authorities and societies around the world. LÄS MER
