  2. 1. Mechanistic-Empirical Modeling of Permanent Deformation in Asphalt Concrete Layers

    Author : Erik Oscarsson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; modeling; Mechanistic-Empirical; rutting; asphalt concrete; full-scale pavements;

    Abstract : Three mechanistic-empirical permanent deformation models were evaluated under Swedish conditions with respect to traffic, climate and materials using accelerated pavement testing and long-term pavement performance studies. The mechanistic-empirical pavement design guide (M E PDG), the incremental-recursive mechanistic-empirical CalME model (CalME), and the PErmanent Deformation of asphalt concrete layer for ROads (PEDRO) model generally showed both useful features and limitations.

  4. 2. Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide

    Author : Erik Oscarsson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; design guide; asphalt concrete; mechanistic empirical;

    Abstract : Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. READ MORE

  5. 3. Towards Mixed Molecular Layers for Dye-Sensitized Solar Cells : A Photoelectron Spectroscopy Study

    Author : Johan Oscarsson; Håkan Rensmo; Erik Johansson; Anders Hagfeldt; Gunnar Öhrwall; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dye-sensitized solar cell; DSC; mesoscopic solar cell; photoelectron spectroscopy; PES; XPS; interface; TiO2; NiO; co-adsorption; co-adsorbent; collaborative sensitization; mixed molecular layers; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The increasing demand for renewable energy has led to substantial research on different solar cell technologies. The dye-sensitized solar cell (DSC) is a technology utilizing dye molecules for light absorption. READ MORE

  6. 4. Perioperative myocardial damage and cardiac outcome in patients-at-risk undergoing non-cardiac surgery

    Author : Anna Oscarsson Tibblin; Christina Eintrei; Sven-Erik Ricksten; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myocardial damage; cardiac complication; outcome; aspirin; acetylsalicylic acid; Anaesthetics and intensive care; Anestesiologi och intensivvård;

    Abstract : Despite increasingly sophisticated perioperative management, cardiovascular complications continue to be major challenges for the clinician. As a growing number of elderly patients with known coronary artery disease (CAD) or with risk factors for CAD are undergoing non-cardiac surgery, cardiovascular complications will remain a significant clinical problem in the future.

  7. 5. Experimental characterization and numerical modeling of compression perpendicular to the grain in wood and cross-laminated timber

    Author : Shaheda T. Akter; Thomas K. Bader; Erik Serrano; Jan Oscarsson; Reinhard Brandner; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling shear; biaxial testing; stress combination; RT-plane; moisture influence; rolling shear creep; digital image correlation; strain field; CLT connection; rotational stiffness; rullskjuvning; biaxiell undersökning; spänningskombination; RT-plan; fuktpåverkan; krypning vid rullskjuving; digital bildkorrelation; töjningsfält; KLTanslutning; rotationsstyvhet; Byggteknik; Civil engineering;

    Abstract : Compression perpendicular to the grain (CPG) of wood is a typical loading situation in timber structures. It has been an extensively studied research topic for decades, due to the highly ductile behavior of wood under such loading, the large variations in mechanical properties, and the relevance of these properties in structural design.
