  1. 16. Combined Assessment of Future Heat Supply and Demand - A Dynamic Systems Approach

    Författare :Karl Vilén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TIMES; Climate policy; Low heat demand housing; District heating; Heating system; Dynamic energy system modeling; Housing;

    Sammanfattning : In order to meet climate change mitigation targets, the use of fossil fuels has to be reduced and, eventually, be phased out in all sectors. As the heating sector occupies a central place in energy systems, especially in Nordic countries, it is affected by and affects other energy sectors. LÄS MER

  3. 17. Economic and Environmental Benefits of CHP-based District Heating Systems in Sweden

    Författare :Shahnaz Amiri; Björn G. Karlsson; Louise Trygg; Mats Westermark; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Future energy systems and thus the climate are affected by many factors, such as energy resources, energy demand, energy policy and the choice of energy technologies. Energy systems of the future are facing three main challenges; the steady growth of global energy demand, the energy resource depletion, as well as the increasing emissions of carbon dioxide (CO2) and other greenhouse gases and their impact on climate change.

  4. 18. Single-Zone Cylinder Pressure Modeling and Estimation for Heat Release Analysis of SI Engines

    Författare :Markus Klein; Lars Eriksson; Lars Nielsen; Per Tunstål; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heat release; parameter estimation; prior knowledge; regularization; specific heat ratio; compression ratio; Systems engineering; Systemteknik;

    Sammanfattning : Cylinder pressure modeling and heat release analysis are today important and standard tools for engineers and researchers, when developing and tuning new engines. Being able to accurately model and extract information from the cylinder pressure is important for the interpretation and validity of the result. LÄS MER

  5. 19. Servicescape for Digital Wellness Services for Young Elderly

    Författare :Hans Allmér; Christer Carlsson; Pirkko Walden; Anna Sell; Leif Marcusson; Siw Lundqvist; Anna Ståhlbröst; Finland Åbo Akademi University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatik; Information Systems; Marketing; Marknadsföring;

    Sammanfattning : In this thesis digital wellness services (DWSs) are in focus. The DWSs are services provided through digital devices, such as smartphones, bracelets, and tablets, by using digital environments such as Internet, cloud services, and websites. LÄS MER

  7. 20. Searching for keys to successful post-merger integration : A longitudinal case-study following a public sector merger

    Författare :Siw Lundqvist; Christer Carlsson; Leif Marcusson; Rune Gustafsson; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; post-merger integration; Information Systems; Informatik;

    Sammanfattning : Unsuccessful mergers are unfortunately the rule rather than the exception. Therefore it is necessary to gain an enhanced understanding of mergers and post-merger integrations (PMI) as well as learning more about how mergers and PMIs of information systems (IS) and people can be facilitated.
