  1. 1. Population and Community Dynamics in Variable Environments

    Detta är en avhandling från Theoretical Ecology, Ecolgy Building, Lund University

    Författare :Jörgen Ripa; Lunds universitet.; Lund University.; [1999]
    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 : Popular Abstract in Swedish Alla naturliga djur- eller växt- populationer varierar i tid och rum. Om man exempelvis räknar antalet individer av en viss art som befinner sig på ett visst ställe varje år, finner man att det antalet varierar från år till år. LÄS MER

  2. 2. Integrated Community Energy Systems

    Detta är en avhandling från Enschede : Gildeprint

    Författare :Binod Prasad Koirala; KTH.; [2017]
    Nyckelord :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

    Detta är en avhandling från Stockholm : Department of Sociology, Stockholm University

    Författare :Hernan Mondani; Stockholms universitet.; [2017]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 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. Microbial Community Assembly during Aerobic Granulation

    Detta är en avhandling från Chalmers University of Technology

    Författare :Raquel Liebana; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; membrane bioreactors; aerobic granular sludge; reproducibility; sequencing batch reactors; washout dynamics; fluorescence in-situ hybridization; granulation; microbial community dynamics;

    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

  5. 5. Species interactions and community structure

    Detta är en avhandling från Peter Frodin, Department of Theoretical Ecology, Ecology Building, S-223 62 Lund, Sweden

    Författare :Peter Frodin; Lunds universitet.; Lund University.; [2002]
    Nyckelord :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
