1. 1. Fatigue Life Prediction in Service - A Statistical Approach

   Författare :Thomas Svensson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fatigue life; sequential effects; variable amplitude fatigue; prediction uncertainties; variable amplitude fatigue;

   Sammanfattning : This thesis treats the problem of fatigue life prediction. The emphasis is on the development of simplified methods, intended to be used in engineering design and the starting point is the established methods for fatigue prediction in service, namely the Wöhler curve, the Paris´ law and the Palmgren-Miner law of cumulative damage.

3. 2. Service life estimation in building design : A development of the factor method

   Författare :Björn Marteinsson; Christer Sjöström; Michael A. Lacasse; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; factor method; service life prediction; durability; degradation; Byggnadsteknik; Building engineering; Byggnadsteknik;

   Sammanfattning : The built environment usually constitutes a very important part of the real capital of a nation, and the construction sector represents more than 10% of the yearly Gross National Product of the industrialised world. Good planning of all construction is important, and consideration of the service life of the work is of great interest and is a significant aspect of sustainability considerations. LÄS MER

5. 4. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction

   Författare :Krishna Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Nicholls John; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. LÄS MER

7. 5. Analysis of enterprise IT service availability : Enterprise architecture modeling for assessment, prediction, and decision-making

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Service Level Agreement; outage costs; Enterprise Architecture; enterprise IT service availability; decision-making; metamodeling; Enterprise Architecture analysis; Bayesian networks; fault trees; Predictive Probabilistic Architecture Modeling Framework; Service Level Agreement; nertidskostnader; Enterprise Architecture; tillgänglighet hos IT-tjänster; beslutsfattande; metamodellering; arkitekturanalys; bayesianska nätverk; felträd; Predictive Probabilistic Architecture Modeling Framework;

   Sammanfattning : Information technology has become increasingly important to individuals and organizations alike. Not only does IT allow us to do what we always did faster and more effectively, but it also allows us to do new things, organize ourselves differently, and work in ways previously unimaginable.
