  1. 31. CALIBRATION OF CHROMATOGRAPHY MODELS

    Författare :Patrik Persson; Avdelningen för kemiteknik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 32. Modelling Aspects of Wastewater Treatment Processes

    Författare :Ulf Jeppsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; thickening; solids flux; simulation; secondary clarifier; protozoa; predators; parameter estimation; model reduction; model identifiability; mathematical modelling; clarification; biofilm; activated sludge; robotteknik; reglerteknik;

    Sammanfattning : Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. LÄS MER

  4. 33. RANS Simulations of Interaction between Premixed Flame and Turbulence using OpenFOAM Library

    Författare :Ehsan Yasari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Turbulent flow; FSC model; Premixed turbulent combustion; OpenFOAM; Simulation; Countergradient turbulent transport; TFC model;

    Sammanfattning : Unsteady multi-dimensional numerical simulation of turbulent flames is a widely recognized tool for research and development of future internal combustion engines capable of satisfying stringent requirements for ultra-low emission and highly efficient energy conversion. To attain success, such simulations need, in particular, elaborated CFD software and predictive models of turbulent burning. LÄS MER

  5. 34. A Novel Approach for Radiotherapy and Radiosurgery Treatment Planning Accounting for High-Grade Glioma Invasiveness into Normal Tissue

    Författare :Wille Häger; Iuliana Toma-Daşu; Marta Lazzeroni; Jesper Kallehauge; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tumor modeling; medical physics; model; simulation; glioblastoma; gbm; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : High-grade gliomas (HGGs) are a type of malignant brain cancer, which include glioblastomas (GBMs). In adults, GBM is the most common malignant primary brain cancer. Attempts to treat patients with GBMs have been conducted for over a century, but the prognosis has only marginally improved. LÄS MER

  7. 35. k-space Models in MRI Using the Concept of Partitions, Applications with special reference to Overhauser-enhanced techniques

    Författare :J Stefan Petersson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; model; Physics; k-space; magnetic resonance imaging; Overhauser; simulation; Fysik;

    Sammanfattning : A new model describing the image formation in magnetic resonance imaging (MRI) has been developed. The k-space description of MRI pulse sequences is expanded by introducing new dimensions to describe the phase dispersion due to flow, acceleration, jerk, diffusion and magnetic field inhomogeneities.
