  1. 21. Estimation of Nonlinear Latent Variable and Mixture Models

    Författare :Johan Vegelius; Shaobo Jin; Fan Yang-Wallentin; Melanie Wall; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; structural equation modeling; semiparametric; EM algorithm; adaptive Gauss-Hermite quadrature approximation; Laplace approximation; zero inflation; Statistics; Statistik;

    Sammanfattning : In this thesis methods are developed for estimation of latent variable models. In particular nonlinear structural equation models are estimated in the presence of ordinal data and mixture models for count data. LÄS MER

  3. 22. Neoehrlichiosis - latent infection of endothelium and immune defense

    Författare :Linda Wass; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neoehrlichia mikurensis; neoehrlichiosis; human; infectious disease; endothelial cell; T cell;

    Sammanfattning : This thesis is a study of the tick-borne pathogen Neoehrlichia (N.) mikurensis that causes the infectious disease neoehrlichiosis in humans. The disease affects both individuals with competent and suppressed immune defense with the majority of the affected being immunosuppressed. LÄS MER

  4. 23. Integrating Latent Heat Storage into Residential Heating Systems : A study from material and component characterization to system analysis

    Författare :Tianhao Xu; Samer Sawalha; Björn Palm; Justin NingWei Chiu; Tianshu GE; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase change material; thermal energy storage; heat pump; load shifting; space heating; Energy Technology; Energiteknik;

    Sammanfattning : Latent heat thermal energy storage (LHTES) systems can be coupled with heat pump (HP) systems to realize heat load shifting on demand side. With phase change material (PCM), well designed LHTES components exhibit high storage energy density and thus have large potentials to be integrated in residence where a compact energy storage solution is needed.

  5. 24. Development of novel molecular and microfluidics tools for identification and characterization of latent HIV-1 reservoir

    Författare :Wang Zhang; Aman Russom; Ujjwal Neogi; Afshin Ahmadian; Utkan Demirci; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; Latent HIV-1 reservoir; HIV-1 characterization; Microfludics; Molecular detection; Medical Technology; Medicinsk teknologi;

    Sammanfattning : The existence of latent HIV-1 reservoir (LR) in all HIV-1 infected patients serves as a major obstacle to completely cure HIV-1 infection. However, up to now there is still no available assay that provides an accurate measurement of the reservoir size. LÄS MER

  7. 25. Latent variable models for multivariate survival and count data

    Författare :Samuli Ripatti; David Clayton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis consists of three papers on multivariate frailty models and one paper on the use of latent class models in genetic association studies. The common theme through the four papers is the use of latent variables to capture complex dependence structures in the data. LÄS MER
