  2. 1. CALIBRATION OF CHROMATOGRAPHY MODELS

    Author : Patrik Persson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

    Abstract : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. READ MORE

  4. 2. 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

  5. 3. Bilinear Regression and Second Order Calibration

    Author : Marie Linder; Pieter Kroonenberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chemometrics; calibration; multivariate; hyphenated methods; matrix data; bilinear model; least squares; singular value decomposition; generalized rank annihilation; trilinear decomposition; parallel factor analysis; principal components regression; partial least squares; prediction; matematisk statistik; Mathematical Statistics;

    Abstract : We consider calibration of second-order (or "hyphenated") instruments for chemical analysis. Many such instruments generate bilinear two-way (matrix) type data for each specimen. The bilinear regression model is to be estimated from a number of specimens of known composition. READ MORE

  6. 4. Modeling and Calibration of Preparative Chromatography

    Author : Niklas Borg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chromatography; Modeling; Simulation; Calibration; Model based analysis;

    Abstract : In my thesis, I have modeled adsorption chromatography and simulated, calibrated, and analyzed models of adsorption chromatography. While my main focus has been modeling and calibration of the models by estimating the parameters, the models used have been partly new. READ MORE

  7. 5. Model calibration methods for mechanical systems with local nonlinearities

    Author : Yousheng Chen; Andreas Linderholt; Thomas Abrahamsson; Gaëtan Kerschen; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model calibration; finite element modelling; nonlinear structural dynamics; pre-test planning; multi-sinusoidal excitation; vibrational testing; cross validation; Maskinteknik; Mechanical Engineering;

    Abstract : Most modern product development utilizes computational models. With increasing demands on reducing the product development lead-time, it becomes more important to improve the accuracy and efficiency of simulations. READ MORE
