  1. 1. Energy performance of multifamily buildings : building characteristic and user influence

    Författare :Jan-Ulric Sjögren; Thomas Olofsson; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy performance; total heat loss coefficient; gain factor; benchmarking; parameter influence; multivariate method; Building engineering; Byggnadsteknik;

    Sammanfattning : Today many professional property holders use different types of software for monthly energy analyses. The data is however often limited to energy and water use, that is paid for by the property holder. In year 2001, financed by the Swedish Energy Agency, the first steps were taken to create a national web based data base, eNyckeln. LÄS MER

    Sammanfattning : This thesis deals with the development of the DP (the Determiner Phrase) in bilingual first (2L1) and in adult second (L2) language acquisition of Italian, with a focus on a case study of Italian as a second first language. The thesis suggests that the bilingual children and the Swedish adult learners develop the Italian DP differently. LÄS MER

  3. 3. Accuracy of material parameter estimation

    Författare :Anders Salomonsson; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : This thesis deals with material parameter estimation for non-linear material models, which is an extremely important part of a finite element analysis. The aim of this work is to both estimate parameters and to quantify the their accuracy. The latter enable a total assessment of how the accuracy at different stages in i.e. LÄS MER

  4. 4. Identifying Influential Observations in Nonlinear Regression : a focus on parameter estimates and the score test

    Författare :Karin Stål; Tatjana von Rosen; Sune Karlsson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Added parameter plot; differentiation approach; influential observation; nonlinear regression; score test; Statistics; statistik;

    Sammanfattning : This thesis contributes to influence analysis in nonlinear regression and in particular the detection of influential observations. The focus is on a regression model with a known mean function, which is nonlinear in its parameters and where the function is chosen according to the knowledge about the process generating the data.

  5. 5. Explicit Influence Analysis in Crossover Models

    Författare :Chengcheng Hao; Tatjana von Rosen; Dietrich von Rosen; Tapio Nummi; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; explicit maximum likelihood estimate; generalised mixed linear model; influential observation; perturbation scheme; statistical diagnostics; Statistics; statistik;

    Sammanfattning : This dissertation develops influence diagnostics for crossover models. Mixed linear models and generalised mixed linear models are utilised to investigate continuous and count data from crossover studies, respectively. LÄS MER
