  1. 1. Modeling Diesel spray combustion using a Detailed Chemistry Approach

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Jonas Edman; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The rapid development of computer hardware during the past decade has contributed substantially to advances in almost all branches of science. Computer modeling is being applied to increasingly small physical scales and increasingly large domains, facilitating the generation of advanced phenomenological models and models based on first principles.

  2. 2. Four Proposals for Enterprise Modeling

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Darek Eriksson; [2004]
    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

  3. 3. Meso-Mechanical Modeling and Analysis of Adhesive Layers

    University dissertation from Chalmers tekniska högskola

    Author : Kent Salomonsson; Högskolan i Skövde.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik; Technology; Teknik; Adhesive layer; Meso-mechanical; Representative Volume Element; Large curvatures; Interphase elements; Evolution algorithm;

    Abstract : This thesis is concerned with the modeling, simulation and analysis of adhesive layers. By use of an in situ scanning electron microscopy study it is found that the adhesive studied in the present thesis has a very complex structure with two different compounds, a mineral and an epoxy/thermoplastic blend.

  4. 4. Meso-Mechanical Modeling of Thin Adhesive Layers

    University dissertation from Chalmers tekninska högskola

    Author : Kent Salomonsson; Högskolan i Skövde.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik; Technology; Teknik; adhesive layer; meso-mechanical; FEM; RVE; SEM;

    Abstract : A thin adhesive layer is analyzed using a representative volume element (RVE). The RVE is comprised by, both continuum and interfacial finite elements. The interface elements allow for crack initiation and crack propagation. To obtain realistic results from the RVE simulation, an in situ scanning electron microscopy (SEM) study is performed.

  5. 5. Efficient modeling and control of crushing processes in minerals processing

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Marcus Johansson; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPGR; Comminution; Jaw crusher; Process control; Modeling; Dynamic modeling; Minerals processing;

    Abstract : Modeling and simulation is a tool to explore and increase the understanding of a phenomenon. This thesis focuses on developing models of crushers and equipment used in the mining industry. Specifically, the focus is on a branch of modeling called time dynamic modeling which is a model that gives an output as a function of time. READ MORE
