  1. 1. Topics in optimal design of experiments

    Författare :Sofia Normark; Hans Nyquist; Johan Lyhagen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimal design; factorial experiments; minimax designs; efficiency; locally optimal designs; generalized linear models; binary data; statistik; Statistics;

    Sammanfattning : This thesis contributes to optimal design of experiments in situations where the optimal design depends on unknown parameters. Such situations often occur when the response variable does not have normal distribution, as is the case with many generalized linear models (GLM) and many models for binary response. LÄS MER

  2. 2. Preliminaries for probabilistic railway sleeper design

    Författare :Johanna Lilja; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor placement; factorial design; Railway sleeper; ballast; load variation; stochastic parameters; correlation length;

    Sammanfattning : Two investigations are presented, which can be seen ascontributions to the aim of introducing a probabilistic designstrategy of railway sleepers in the future. When usingprobabilistic design the statistics of all relevant parametersconsidered as stochastic must be known. LÄS MER

  3. 3. Increasing Product Quality by Verification and Validation Improvements in an Industrial Setting

    Författare :Tomas Berling; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software Verification; Software Engineering; Software Validation; Process Improvement; Software Process Metrics; Factorial Design; Software Inspection; computer technology; Systems engineering; Data- och systemvetenskap;

    Sammanfattning : Large and complex software systems are developed as a tremendous engineering effort. The aim of the development is to satisfy the customer by delivering the right product, with the right quality, and on time. LÄS MER

  4. 4. Explosions in urban environments: Modelling of gas explosions and risk of premature shear failure in reinforced concrete structures

    Författare :Fabio José Lozano Mendoza; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blast strength; urban road environments; computational fluid dynamics; blast loading; Vapour cloud explosions; factorial design; premature shear failure; Monte Carlo method; model uncertainty;

    Sammanfattning : The risk for accidental gas explosions in urban environments has increased in Sweden in recent years. This is due to densification of existing urban centres and the rise of vehicles powered by alternative fuels. LÄS MER

  5. 5. Empirical Bayes Methods for DNA Microarray Data

    Författare :Ingrid Lönnstedt; Allan Gut; Tom Britton; Mette Langaas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; two-channel microarrays; differential expression; replication; empirical Bayes; factorial design; interaction; time trends; hierarchical Bayes; MCMC simulations; ANOVA; F-statistics; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Sammanfattning : cDNA microarrays is one of the first high-throughput gene expression technologies that has emerged within molecular biology for the purpose of functional genomics. cDNA microarrays compare the gene expression levels between cell samples, for thousands of genes simultaneously.
