  2. 11. Four Proposals for Enterprise Modeling

    Author : Darek Eriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; change; development; enterprise; modeling process; enterprise modeling language; systems science; constructivist epistemology; organization; modeling; multi-modal modeling; model;

    Abstract : Any enterprise whether a major corporation, a small family-owned business, a public school, a hospital, or a military unit needs to develop itself continuously in order to adapt to the challenges originating within itself and from its environment, in relation to its overall purpose or mission. Deliberate development and management of an enterprise manifest complexity that gives rise to a central challenge: how can we obtain a comprehensive intelligibility of an enterprise? One conceptual tool to overcome this challenge is enterprise modeling; it supports articulation of an enterprise and consequently intelligibility of its complexity. READ MORE

  4. 12. Modeling the influence of magnesium from alternative raw materials on the chemistry of Portland cement clinker

    Author : Erik Viggh; Rainer Backman; Dan Boström; Bo Björkman; Umeå universitet; []

  5. 13. Modeling and Simulation of Physical Systems in a Mechatronic Context

    Author : Carl-Johan Sjöstedt; Martin Törngren; Hans Vangheluwe; KTH; []
    Keywords : mechatronics; MATLAB Simulink; SysML; bond graphs; Modelica; Simscape; simulation; modeling; EAST-ADL2; physical modeling; Mechanical engineering; Maskinteknik;

    Abstract : This thesis gives different views on the modeling and simulation of physical systems, especially together with embedded systems, forming mechatronic systems. The main considered application domain is automotive. READ MORE

  6. 14. Modeling Organizational Dynamics : Distributions, Networks, Sequences and Mechanisms

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

    Abstract : 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. READ MORE

  7. 15. Heat Balance Modeling of a Stationary Fluidized-Bed Furnace Burning Biomass

    Author : Fredrik Niklasson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixing; modeling; biomass; dispersion; heat balance; fluidized bed boiler;

    Abstract : The influence of biomass fuel properties on the heat balance of the bottom region (bed and splash zone) of a commercial-scale bubbling fluidized-bed furnace is investigated theoretically and experimentally. The experiments have been carried out at the Chalmers 12 MWth research boiler, operated under non-circulating conditions during most of the experiments. READ MORE
