  2. 6. Scattering of seismic waves in random velocity models : Finite difference simulation

    Author : Lena Frenje; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The small-scale heterogeneities within the Earth's crust and the effect these heterogeneities have on seismic waves have gained increasing interest in the last 15 years. One approach to study seismic wave scattering is through numerical simulations in random media. READ MORE

  4. 7. Integrating Discrete Event Simulation into the Engineering Process Strategic Solutions for Increased Efficiency in Industrial System Development

    Author : Pär Klingstam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete event simulation; manufacturing system development; simulation methodology; simulation strategy; engineering integration;

    Abstract : Efficient development processes are the key to being competitive, signified by short development lead times, low development costs, and high quality in all development activities. Previous research in academia as well as in industry suggested two important facilitators for obtaining such processes, namely structured development and modeling and simulation. READ MORE

  5. 8. Numerical Modelling of Self-Compacting Concrete Flow : Discrete and Continuous Approach

    Author : Annika Gram; Johan Silfwerbrand; Ali Farhang; Mette R. Geiker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SCC; rheology; Simulation of Flow; Simulering; Flöde; Självkompakterande Betong; Reologi; Construction materials; Konstruktionsmaterial;

    Abstract : With the advent of Self-Compacting Concrete (SCC) that flows freely, under the soleinfluence of gravity, the wish for hassle-free and predictable castings even in complexcases, spurged the simulation of concrete flow as a means to model and predictconcrete workability. To achieve complete and reliable form filling with smoothsurfaces of the concrete, the reinforced formwork geometry must be compatible withthe rheology of the fresh SCC. READ MORE

  6. 9. Modeling and Simulation of Physical Systems in a Mechatronic Context

    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

  7. 10. Safety, Security, and Semantic Aspects of Equation-Based Object-Oriented Languages and Environments

    Author : David Broman; Peter Fritzson; Henrik Nilsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modeling; Simulation; Equation-Based; Object-Oriented; Modelica; Type System; Semantics; Language Safety; Secure Simulation; Computer science; Datavetenskap;

    Abstract : During the last two decades, the interest for computer aided modeling and simulation of complex physical systems has witnessed a significant growth. The recent possibility to create acausal models, using components from different domains (e.g., electrical, mechanical, and hydraulic) enables new opportunities. READ MORE
