  2. 1. Methods for Optimal Model Fitting and Sensor Calibration

    Author : Erik Ask; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Model Fitting; Sensor Networks; Computer Vision; Polynomial Equations; Action Matrix Methods;

    Abstract : The problem of fitting models to measured data has been studied extensively, not least in the field of computer vision. A central problem in this field is the difficulty in reliably find corresponding structures and points in different images, resulting in outlier data. READ MORE

  5. 3. Segmentation and fitting for geometric reverse engineering : processing data captured by a laser profile scanner mounted on an industrial robot

    Author : Mohamed Rahayem; Johan Kjellander; Sören Hilmerby; Naoufel Werghi; Örebro universitet; []
    Keywords : Geometric Reverse Engineering; Industrial robot; Laser profile scanner; Segmentation; Fitting; TECHNOLOGY; TEKNIKVETENSKAP; Mechanical engineering; Maskinteknik; Maskinteknik; Mechanical Engineering;

    Abstract : Geometric Reverse Engineering (GRE) is the problem of creating CAD models of real objects by measuring point data from their surfaces. The GRE process is usually divided into four sub processes, data capturing, preprocessing, segmentation, fitting and finally CAD model creation. To automate the GRE process the sub processes need to be integrated. READ MORE

  6. 4. 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

  7. 5. Approaching well-founded comprehensive nuclear data uncertainties : Fitting imperfect models to imperfect data

    Author : Petter Helgesson; Henrik Sjöstrand; Helmut Leeb; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evaluated nuclear data; uncertainty propagation; uncertainty quantification; model defects; Gaussian processes; TALYS; TENDL; covariances.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : Nuclear physics has a wide range of applications; e.g., low-carbon energy production, medical treatments, and non-proliferation of nuclear weapons. Nuclear data (ND) constitute necessary input to computations needed within all these applications. READ MORE
