2. 1. Reliable and deterministic network services

   Author : Florian-Daniel Otel; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; queuing delay guarantees; service curve; constraint-based routing; TCP; network security; arrival curve; network failure recovery; traffic engineering; network calculus; traffic envelope;

   Abstract : In a post Internet bubble economic environment the obvious lack of any disruptive new technologies that could give new impetus to network growth (as, for example, experienced after the appearance of the Web) lead to a trivialization of network services: Aside grass-roots, semi-subterranean applications like file sharing, entertainment content swapping and on-line gaming, it can be argued that network services are presently used in a manner not very different than a decade ago. In this respect, one of the factors that can be identified as limiting further development is the perceived lack of guarantees with regard to network services. READ MORE

4. 2. Integrated Product Service Offerings for Rail and Road Infrastructure : Reviewing Applicability in Sweden

   Author : Sofia Lingegård; Mattias Lindahl; Niclas Svensson; Daniel Brissaud; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated Product Service Offerings; Product Service Systems; long-term contracts; risk; life-cycle perspective; resource-efficiency;

   Abstract : This research aims to explore and propose a more effective management of rail and road infrastructure and the possibility of a more resource-efficient road and rail infrastructure by applying business models based on performance and a life-cycle perspective.There is a lack of efficiency in the Swedish rail and road infrastructure industries - at the same time as the availability of the rail tracks and roads is essential.

5. 3. Energy Transitions, Economic Growth and Structural Change: Portugal in a Long-run Comparative Perspective

   Author : Sofia Henriques; Ekonomisk-historiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy; natural resources; Environmental Kuznets Curve; Portugal; industrialization; service transition; structural change; electrification; XIX and XX centuries.;

   Abstract : This book analyses, in an international comparative context, Portugal´s energy transition from organic sources to fossil fuels in the period 1856-2006. It investigates the role that energy played in the industrialization of the country and how the relationship between energy and economic growth changed with the transition from an industrial to a service society.

6. 4. Fatigue Life Prediction in Service - A Statistical Approach

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

   Abstract : 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.

7. 5. Natural resources and sustainable energy : Growth rates and resource flows for low-carbon systems

   Author : Simon Davidsson; Mikael Höök; Gert Jan Kramer; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low-carbon technology; renewable energy; energy transitions; critical materials; energy metals; material flows; net energy; EROI; life cycle assessment; LCA; growth curves; curve fitting; resource depletion; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

   Abstract : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.
