  1. 1. Population and Community Dynamics in Variable Environments

    Författare :Jörgen Ripa; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dispersal; Moran effect; linear dynamics; synchrony; power spectrum; autocorrelation; extinction risk; population dynamics; environmental stochasticity; migration; stochastic modelling; Ecology; Ekologi;

    Sammanfattning : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. LÄS MER

  2. 2. Integrated Community Energy Systems

    Författare :Binod Prasad Koirala; Mehrdad Ghandari; Rudi A. Hakvoort; Reinier Van der Veen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed energy resources; community energy; local energy systems; institutional design; smart grids; energy system integration; community engagement; Energiteknik; Energy Technology; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Energy systems across the globe are going through a radical transformation as a result of technological and institutional changes, depletion of fossil fuel resources, and climate change. Accordingly, local energy initiatives are emerging and increasing number of the business models are focusing on the end-users. LÄS MER

  3. 3. Modeling Organizational Dynamics : Distributions, Networks, Sequences and Mechanisms

    Författare :Hernan Mondani; Fredrik Liljeros; Rickard Sandell; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; organizational dynamics; social organizing; organizational change; modeling; organizational growth; process stability; labor flow network; employment trajectories; heavy-tailed distributions; complex network analysis; sequence analysis; agent-based modeling; sociophysics; Sociology; sociologi;

    Sammanfattning : The study of how social organizations work, change and develop is central to sociology and to our understanding of the social world and its transformations. At the same time, the underlying principles of organizational dynamics are extremely difficult to investigate. LÄS MER

  4. 4. Species interactions and community structure

    Författare :Peter Frodin; Technology and Social Change (WTS) Centre for Work; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; spatial structure; local stability; enrichment; species interactions; Community structure; population dynamics;

    Sammanfattning : In this theses I have focused on how the mechanisms of species interactions affect community structure. It is well known that certain species may have a particularly strong influence on the structure of a community. What is not fully understood is how to characterize these species that have such a strong impact on community structure. LÄS MER

  5. 5. Microbial Community Assembly during Aerobic Granulation

    Författare :Raquel Liebana; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; aerobic granular sludge; granulation; washout dynamics; membrane bioreactors; sequencing batch reactors; fluorescence in-situ hybridization; microbial community dynamics; reproducibility;

    Sammanfattning : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. LÄS MER
