  1. 6. Identification and synthesis of components for uncertainty propagation

    Författare :Mladen Gibanica; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substructuring; uncertainty propagation; uncertainty quantification; surrogate modelling; Monte Carlo method; interface reduction; state-space models; experimental methods; system identification;

    Sammanfattning : For automotive structures, built-up of hundreds of components with property spread, knowing the effects of component variability and its propagation through the system assembly is important in order to mitigate noise and vibration problems. To increase the understanding of how the spread propagates into variability in built-up structures, both experimental and computational aspects are considered in this thesis. LÄS MER

  3. 7. Modelling Climate Policy – Trade-Off Metrics, Resource Markets, and Uncertainty

    Författare :Daniel Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OPEC; GWP; energy; uncertainty; biomass; climate change; oil; land use; greenhouse gases; Kyoto Protocol;

    Sammanfattning : This thesis consists of five papers related to climate change policy. In paper I andpaper II we discuss the use of Global Warming Potentials (GWPs) that facilitate the tradeoffbetween abatement of the different greenhouse gases (GHGs). LÄS MER

  4. 8. Drivers of global land use change : are increasing demands for food and bioenergy offset by technological change and yield increase?

    Författare :Kerstin Engstrom; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Global land use change; food demands; bioenergy demands; technological change; modelling; scenarios; uncertainty;

    Sammanfattning : Globally, the food and energy demands of the growing global population are rising and require increased agricultural production. Additionally, climate change will have adverse effects on agricultural productivity. LÄS MER

  5. 9. Human Behaviour in Social-Ecological Systems : Insights from economic experiments and agent-based modelling

    Författare :Caroline Schill; Therese Lindahl; Anne-Sophie Crépin; Johan Colding; Carl Folke; Juan Camilo Cárdenas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human behaviour; Common-pool resources; Ecological complexity; Collective action; Sustainable resource use; Regime shifts; Thresholds; Uncertainty; Communication; Knowledge-sharing; Economic experiments; Laboratory and field experiments; Agent-based modelling; Complex adaptive systems; Social-ecological systems; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Progress towards sustainability requires changes in our individual and collective behaviour. Yet, our fundamental understanding of behaviour in relation to environmental change remains severely limited. LÄS MER

  7. 10. Assessing future effects on lake ecosystem resilience using data analysis and dynamic modelling : Modelling the effects of extreme weather events and climate warming on lakes

    Författare :Jorrit P. Mesman; Bastiaan W Ibelings; Stéphane Goyette; Don C Pierson; Karsten Rinke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extreme events; Storms; Modelling; Climate change; Thermal structure; Phytoplankton;

    Sammanfattning : Extreme weather events can have short-term and long-term effects on lake thermal structure, nutrient dynamics, and community composition. Moreover, changes in lake variables induced by global climate change may influence the response and recovery of lake ecosystems to extreme weather events. LÄS MER
