  1. 36. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model

    Författare :Olle Eriksson; Stig Danielsson; Rolf Sundberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Emission; Grid; Model; Pollutant; Response surface; Road traffic; Sensitivity analysis; Simulation; Uncertainty analysis; Avgaser; Vägtrafik; Miljöaspekter; Statistics; Statistik;

    Sammanfattning : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. LÄS MER

  3. 37. Uncertainty and Risk Analysis in Fire Safety Engineering

    Författare :Håkan Frantzich; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event tree; fire engineering design; reliability index; FOSM; Monte Carlo simulation; Risk analysis; uncertainty analysis; response surface.; Technological sciences; Teknik;

    Sammanfattning : Two Quantitative Risk Analysis (QRA) methods are presented which can be used to quantify the risk to occupants in, for example, a building in which a fire has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. LÄS MER

  4. 38. Immune response in human tonsil tissue

    Författare :Karin Ågren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Tonsillar hypertrophy; reeurrent tonsillitis; infectious mononueleosis; cytokine; immune response.;

    Sammanfattning : Pathogenic mechanisms responsible for tonsillar hypertrophy (TH) in children suffering from obstructive sleep apnea syndrome (OSAS) were studied and compared with children with recurrent tonsillitis (RT) and infectious mononucleosis (IM), respectively. In an initial study the clinical consequences of OSAS caused by TH was investigated. LÄS MER

  5. 39. On the initial inflammatory response to variations in biomaterial surface chemistry

    Författare :Felicia Suska; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Aims. The aim of the present thesis was, firstly, to develop in vivo and ex vivo models for analysis of peri-implant exudate and implant adherent cells and, secondly, to characterize the early inflammatory response to materials with different surface chemical functionalization as well as materials with inert (Ti) and cytotoxic (Cu) properties.

  7. 40. A Theoretical Study of Piezoelectricity, Phase Stability, and Surface Diffusion in Disordered Multicomponent Nitrides

    Författare :Christopher Tholander; Björn Alling; Ferenc Tasnádi; Lars Hultman; Susanne Mirbt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Piezoelectricity; phase stability; surface diffusion; disordered multicomponent nitrides;

    Sammanfattning : Disordered multicomponent nitride thin film can be used for various applications. The focus of this Licentiate Thesis lies on the theoretical study of piezoelectric properties, phase stability and surface diffusion in multifunctional hard coating nitrides using density functional theory (DFT).
