  1. 1. Drag Reduction by means of Active Flow Control Applied on a Generic Truck A-pillar: a Numerical and Experimental Study

    Författare :Guglielmo Minelli; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PANS; Large Eddy Simulation; Wind Tunnel.; Bluff Body Flow; Modal Decomposition; Experiments; Vehicle Aerodynamic; POD; Active Flow Control; LES; Partially Averaged Navier Stokes; AFC;

    Sammanfattning : The overall goal of this thesis is to isolate and control the flow mechanism characterizing the flow separation occurring at the A-pillar of a truck. The study aims to gain knowledge of the flow physics of the separation mechanism, and to eventually suppress the afore mentioned separation by means of an Active Flow Control. LÄS MER

  3. 2. Active Flow Control for Reducing Drag on Trucks: from Concept to Full Scale Testing

    Författare :Guglielmo Minelli; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AFC; Experiments; Vehicle Aerodynamics; Partially-Averaged Navier-Stokes; PANS; LES; Wind Tunnel; POD; Active Flow Control; Large Eddy Simulations; Proper Orthogonal Decomposition; PIV;

    Sammanfattning : There is no doubt that road vehicle transportation is needed to improve efficiency, to reduce power consumption and to contribute to a sustainable mobility. Aerodynamics plays a crucial role in this, and its optimization can have a significant impact on fuel efficiency. LÄS MER

  4. 3. Characterization and long-term follow-up of Pediatric Acute-onset Neuropsychiatric Syndrome (PANS)

    Författare :Caroline De Visscher; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Pediatric acute-onset neuropsychiatric syndrome (PANS) is a cluster of psychiatric and somatic symptoms of proposed autoimmune etiology. It remains a descriptive entity, still of unclear validity and uncertain clinical utility. LÄS MER

  5. 4. Pediatric acute neuropsychiatric syndrome : diagnosis, biomarkers and treatment

    Författare :Eva Hesselmark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS) and Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) are proposed diagnoses combining a clinical picture of acute onset obsessive compulsive disorder, tics or eating disorders with a suggested inflammatory pathogenesis. However, it remains uncertain if patients with PANS or PANDAS differ from other psychiatric patients with regard to symptoms, disorder course or symptom load at onset. LÄS MER

  7. 5. Macrophages and neutrophils in tissue homeostasis and recovery from ischemic injury

    Författare :Kristel Parv; Mia Phillipson; Gustaf Christoffersson; Per-Ola Carlsson; Stephen Jenkins; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; macrophages; neutrophils; hindlimb ischemia; ischemic disease; mural cells; diabetes mellitus; postnatal β cell maturation.;

    Sammanfattning : Neutrophils and macrophages have functions beyond protection against pathogens. The overall aim of the work presented in this thesis was to identify novel tasks for these innate immune cells in maintaining homeostasis. LÄS MER
