  2. 2. Extensions of the kernel method of test score equating

    Author : Gabriel Wallin; Marie Wiberg; Jenny Häggström; Anton A. Béguin; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Test equating; Nonequivalent groups; Standard error of equating; bandwidth selection; log-linear models; item response theory; Statistics; statistik;

    Abstract : This thesis makes contributions within the area of test score equating and specifically kernel equating. The first paper of this thesis studies the estimation of the test score distributions needed in kernel equating. READ MORE

  3. 3. Superfluid Phase Transitions in Disordered Systems

    Author : Hannes Meier; Mats Wallin Wallin; Peter Olsson; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents results from large scale Monte Carlo simulations of systems subject to a superfluid phase transition in the presence of disorder. The simulations are performed by state-of-the-art, collective Monte Carlo algorithms treating phase degrees of freedom in effective models with amplitude fluctuations integrated out. READ MORE

  4. 4. Hyperthyroidism : a chronic disease?

    Author : Gabriel Sjölin; Göran Wallin; Mikael Lantz; Laszlo Hegedus; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyperthyroidism; Graves’ disease; toxic nodular goitre; longterm follow-up; Quality of Life; radioactivated iodine; antithyroid drugs; thyroidectomy; index patient;

    Abstract : During 2003-2005, approximately 3,000 de novo hyperthyroid patients were collected in Sweden and became one of the world's largest hyperthyroidism studies. This dissertation shows that many people diagnosed with hyperthyroidism live with its impacts even after excess of thyroid hormone has ended. READ MORE

  5. 5. Foodborne Virulence: Staphylococcus aureus Enterotoxins A and D

    Author : Nina Wallin; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental factors; phage-encoded virulence; in vivo; enterotoxin D; enterotoxin A; gene expression; Staphylococcus aureus; virulence;

    Abstract : The development of new, minimally processed food products challenges traditional concepts of food safety. How pathogenic bacteria behave in these new matrices is not known. To fill this knowledge gap and enable the production of food that is safe for the consumer, more information on virulence expression of pathogens in food matrices is required. READ MORE
