  1. 36. Modeling Organizational Dynamics : Distributions, Networks, Sequences and Mechanisms

    Författare :Hernan Mondani; Fredrik Liljeros; Rickard Sandell; Stockholms universitet; []
    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

    Sammanfattning : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. LÄS MER

  4. 38. Machine Tool Dynamics - A constrained state-space substructuring approach

    Författare :Anders Liljerehn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; State-space component synthesis; System identification; Receptance coupling; Chatter stability; Metal cutting; State-space models;

    Sammanfattning : Metal cutting is today one of the leading forming processes in the manufacturing industry. The metal cutting industry houses several actors providing machine tools and cutting tools with a fierce competition as a consequence. Extensive efforts are made to improve the performance of both machine tools and cutting tools. LÄS MER

  5. 39. Ecological systems in space: From islands to contiguous landscapes

    Författare :Ankit Vikrant; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ecosystem stability; metacommunity; Metapopulation; community assembly; species area relationships; complex ecological systems;

    Sammanfattning : Dispersal and interaction networks underlie many ecological systems, often dictating spatio-temporal dynamics as well as emergent patterns. Dispersal has implications for establishment for distinct subpopulations of individual species as well as for the emergence of universal spatial patterns and varied community level structures.

  7. 40. Stability Properties of Switched Dynamical Systems A Linear Matrix Inequality Approach

    Författare :Marcus Rubensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The dynamical properties of many natural phenomena are traditionally described by smooth differential equation models. The use of automated control structures imposes new behaviors on the controlled system. Actions are often organized in a logical manner. Switched dynamical models are a natural extension to smooth differential equation models. LÄS MER
