1. 1. Women's varying life careers and shifting life-patterns : a study of Swedish women born in 1948

   Författare :Eva Wirén; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; life-career; life-pattern; difference; representation; longitudinal; quantitative; text; stories; Bourdieu; post-structural theories; deconstruction; feminism;

   Sammanfattning : This study is about a generation of Swedish women's varying life-careers and shifting lifepatterns. As empirical base for the study is used a longitudinal data material collected at the two main time-points, in 1961 and in 1980. The purpose of the study is twofold. LÄS MER

3. 2. Performance Measures of Road Infrastructure - A Life Cycle Thinking Approach

   Författare :Babak Ebrahimi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road infrastructure; Life Cycle Assessment LCA ; Lifetime Estimation; Geographic Information System GIS ; Life Cycle Thinking LCT ; Material Flow Analysis MFA ;

   Sammanfattning : Roads have been an important asset of human society and the approach we adopt towards planning, designing, constructing, operating, and maintaining of the road infrastructure has significant consequences in the long-term for not only the humans, but all species on planet Earth. Hence, the lifecycle performance of the road infrastructure that sustain our socioeconomic development with a low environmental impact, while fulfilling their technical and functional requirements is of critical importance and needs to be improved.

4. 3. A new family of survival functions and a method for measuring risk inequalities

   Författare :Harald Hannerz; Statistiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mortality law; survival analysis; risk inequalities; excess fraction; Mortality law; survival analysis; risk inequalities; excess fraction;

   Sammanfattning : The present compilation thesis is divided into two sections, one for each of two separate methodological issues: reduction of random errors in mortality estimates and offsetting random variation related bias in data generated estimators of risk inequalities. Summary of section A In regard to the first issue a new family of survival functions is proposed. LÄS MER

5. 4. Condition monitoring of machine tools and machining processes using internal sensor signals

   Författare :Jari Repo; Mihai Nicolescu; Dragos Axiente; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring; machine tool; machining process; milling; position encoders; signal analysis; Mechanical engineering; Maskinteknik; Materials science; Manufacturing and materials engineering;

   Sammanfattning : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and achieving a more robust machining process. Failures in the machining process and machine tool components may also have negative effects on the final produced part. LÄS MER

7. 5. Development of an Environment-Accident Index : A planning tool to protect the environment in case of a chemical spill

   Författare :Åsa Scott Andersson; Mats Tysklind; Ingrid Fängmark; Olof Stjernström; Stellan Fisher; Per Leffler; Ronald Wennersten; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Environment-Accident Index; Chemical Accidents; environmental effects; questionnaire; expert judgements; statistical multivariate design; PCA; PLS; Miljökemi; Environmental chemistry; Miljökemi;

   Sammanfattning : The increasing mass and complexity of chemicals being produced and transported has resulted in more rigorous demands on both authorities as well as chemical-handling industries to assess the risks involved. The Environment-Accident Index (EAI), has been proposed as a planning tool created as an equation in which chemical properties (variables describing the chemical involved) are combined with site-specific properties (variables describing the accident site).
