  2. 16. In conversation with simulation: The application of numerical simulation to the design of structural nodal connections

    Author : Jens Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; 3D Printing; Design theory; Structural design; Structural efficiency; Simulation; Peridynamics; Force flux density; Nodal connections; Conceptual design; Steel structures; Design process; Digital design;

    Abstract : The thesis explores methods for integration of structural analysis, design and production in a digital design environment. The somewhat ambiguous title implies the ambition to make such integration in relation to the explorative phase of the design process which is described by Donald Schön as having a conversational character.

  4. 17. Dynamic Modelling and Simulation of Liquid Food Process Lines

    Author : Tomas Skoglund; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process lines; Dynamic model; Microbial deactivation; Data- och systemvetenskap; computer technology; Systems engineering; Fuzzy traceability; Traceability; Thermal engineering; termodynamik; Termisk teknik; applied thermodynamics; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Heat exchanger; Dispersion; Fluid property transition; Liquid food; Dynamic simulation; Livsmedelsteknik;

    Abstract : In the present work a dynamic model library of components for process lines was developed. The analysis addressed characteristic aspects of liquid food process lines, and new models were developed for fluid transitions, dispersion, mixing zones and first-order chemical reactions in pipes and heat exchangers.

  5. 18. Ruin probabilities and first passage times for self-similar processes

    Author : Zbigniew Michna; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Simulation of Ruin Probability; Monte Carlo Method; Skorokhod Topology; Weak Convergence; Rice s Formula; Fluid Model; Risk Model; Scaled Brownian Motion; Long Range Dependence; Fractional Brownian Motion; Renewal Process; Levy Motion; Stable Process; Self-Similar Process; Gaussian Process; Ruin Probability; First Passage Time; Exponential Bound; Picands Constant.; Mathematics; Matematik;

    Abstract : This thesis investigates ruin probabilities and first passage times for self-similar processes. We propose self-similar processes as a risk model with claims appearing in good and bad periods. Then, in particular, we get the fractional Brownian motion with drift as a limit risk process.

  6. 19. Discrete Element Modelling and Simulation of Vibratory Screens

    Author : Ali Davoodi; Chalmers tekniska högskola; []
    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; Screen efficiency; Modelling.; DEM simulation;

    Abstract : In Sweden about 85 million tonnes aggregate is used for road, railway and concrete every year. Crushing is the main process for producing the aggregate material in different fractions. The crushing process is divided into two sub-processes; comminution and separation. READ MORE

  7. 20. Reflections on Process-based Supply Chain Modelling and Analysis

    Author : Robert Lindroth; Teknisk logistik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process mapping; supply chain management; modelling; simulation.;

    Abstract : The interest in modelling, analysis and optimisation of supply chain structures has increased in the last decade. Among the reasons are globalisation, a general speed-up of the rate of change in the business environment, the trend towards more outsourcing of activities, and the rapid development in IT. READ MORE
