  1. 31. Robust Design Experimentation and Dispersion Effects

    Författare :Martin Arvidsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; estimation procedure; design of experiments; generalized linear models; event matrices; variance component; location effects; split-plot experiments; robust design; identification procedure; dispersion effects;

    Sammanfattning : One of the most common methods in robust design methodology is design of experiments. This method makes it possible to identify settings of design factors that make products and production processes robust with respect to noise factors. LÄS MER

  3. 32. Epidemiological aspects of musculoskeletal pain in the upper body. Analyzing common and recurrent binary outcomes

    Författare :Anna Grimby-Ekman; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; musculoskeletal; pain; neck; repeated measurements; logistic model; odds ratio OR ; risk ratio RR ; risk difference RD ; biological interaction;

    Sammanfattning : The overall aim of this thesis is to gain epidemiological knowledge about musculoskeletal pain in the upper body in light physical work, in relation to gender, psychosocial factors, and computer use; and to compare different methods for analyzing common and recurrent binary outcomes. Two study groups were investigated using questionnaire data: (a) computer users in the Swedish workforce and (b) a cohort of university students. LÄS MER

  4. 33. Climate regulation provided by urban greening - examples from a high latitude city

    Författare :Janina Konarska; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gothenburg; Sweden; high latitude city; urban greenery; urban trees; leaf area index; tree transpiration; sky view factor; mean radiant temperature; hemispherical photography; climate-sensitive planning;

    Sammanfattning : Cities exert a strong influence on urban climate, and consequently on human health and wellbeing. This increases the importance of considering climate issues in urban planning, particularly in the context of global climate change. One of the key adaptation strategies in climate-sensitive planning is urban greenery. LÄS MER

  5. 34. Glycaemic control: evaluation of HbA1c as a risk factor and the effect of modern insulins in clinical practice

    Författare :Marcus Lind; Göteborgs universitet; []
    Nyckelord :HbA1c; glargine; lispro; time; retinopathy; clinical practice; electronical tracking; record system;

    Sammanfattning : One of the ultimate goals of diabetes care is to minimise diabetic complications. When evaluating insulins it is important to understand what extent of improvements in glycaemic control is clinically relevant in preventing diabetic complications. LÄS MER

  7. 35. Essays on Panel Data with Multidimensional Unobserved Heterogeneity

    Författare :Yana Petrova; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Econometrics; Factor-Augmented Panel Regression; Interactive Effects; Unknown Factors; CCE Estimation; Principal Components;

    Sammanfattning : This thesis contributes to econometric methodology in terms of estimation and inference in static panel data models with unobserved multidimensional heterogeneity. When not properly accounted for, unobserved heterogeneity may introduce bias into the parameter estimates associated with covariates of interest, such as treatment indicators or determinants of macroeconomic indicators.
