  2. 21. On Model Libraries for Thermo-hydraulic Applications

    Author : Jonas Eborn; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; simulation; Matematik; Automation; Termisk teknik; control systems; nonlinear models; parameter estimation; proces s control; thermo-hydraulic systems; model validation; Thermal engineering; applied thermodynamics; termodynamik; Automatiska system; robotics; control engineering; reglerteknik; robotteknik; Mathematics; object-oriented;

    Abstract : Mathematical modelling and simulation are important tools when dealing with engineering systems that today are becoming increasingly more complex. Tightly integrated production and process optimization are trends that give rise to heterogeneous systems, which are difficult to handle without expertise in several engineering disciplines.

  4. 22. Simulation of Wheel and Rail Profile Evolution : Wear Modelling and Validation

    Author : Roger Enblom; KTH; []
    Keywords : contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction. READ MORE

  5. 23. The construction, analysis and validation of mechanistic mathematical models of protein kinetics in the context of replicative ageing in budding yeast

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein kinetics; Replicative ageing; Cdc42; Ordinary differential equations; Reaction diffusion models; Parameter estimation; Model validation; Model construction; Symmetry methods;

    Abstract : Mathematical modelling constitutes a forceful tool for elucidating properties of biological systems. Using theoretical approaches in combination with experimental techniques it is possible to study specific molecular aspects of phenomena such as the ageing of human beings. READ MORE

  6. 24. Calibration and Reduction of Large-Scale Dynamic Models - Application to Wind Turbine Blades

    Author : Majid Khorsand Vakilzadeh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum likelihood estimator; model reduction; finite element model calibration; Bayesian model calibration; Verification and validation; wind turbine blade; logarithmic least square estimator; large-scale dynamics model; SWPTC;

    Abstract : This thesis investigates the validity of structural dynamics models of wind turbine blades. An outlook on methods for model calibration to make models valid for their intended use is presented in the thesis. The intention is to make the models valid for robust predictions. The model validity is here assessed to be of hierarchical dual level. READ MORE

  7. 25. Experimental Validation of a Phased Array Ultrasonic Testing Probe Model and Sound Field Optimization

    Author : Xiangyu Lei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phased array; Sound field optimization; Experiments; Validation;

    Abstract : New manufacturing technologies are developed to facilitate flexible product designs and production processes. However, the quality of the final products should not be compromised, especially for safety prioritized industries, e.g. aerospace industry. READ MORE
