  1. 21. Sharing Economy Business Models : Addressing the design-implementation gap

    Författare :Steven Curtis; Internationella miljöinstitutet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sharing economy; sharing economy business models; sustainable business models; Design Science Research DSR ;

    Sammanfattning : Despite sharing being a long-practiced form of consumption, the concept ‘sharing economy’ has emerged only recently. New business models have proliferated, utilising technology to reduce transaction costs and facilitate shared access. LÄS MER

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

    Författare :Simon Davidsson; Mikael Höök; Gert Jan Kramer; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; 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;

    Sammanfattning : 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.

    Sammanfattning : Within the electric power industry, the average company's enterprise system - i.e. the overall system of IT related entities - is today highly complex. LÄS MER

  4. 24. Energy-efficient cloud computing : autonomic resource provisioning for datacenters

    Författare :Selome Kostentinos Tesfatsion; Johan Tordsson; Eddie Wadbro; Erik Elmroth; Laurent Lefevre; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud computing; datacenter; energy-efficiency; performance management; virtualization;

    Sammanfattning : Energy efficiency has become an increasingly important concern in data centers because of issues associated with energy consumption, such as capital costs, operating expenses, and environmental impact. While energy loss due to suboptimal use of facilities and non-IT equipment has largely been reduced through the use of best-practice technologies, addressing energy wastage in IT equipment still requires the design and implementation of energy-aware resource management systems.

  5. 25. From Competitive to Cooperative Resource Management for Cyber-Physical Systems

    Författare :Mikael Lindberg; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource management; feedback; real-time; optimization; peer-to-peer; cyber-physical systems;

    Sammanfattning : This thesis presents models and methods for feedback-based resource management for cyber-physical systems. Common for the scenarios considered are severe resource constraints, uncertain and time-varying conditions and the goal of enabling flexibility in systems design rather than restricting it. LÄS MER
