  1. 1. Restraint in structures with young concrete : Tools and estimations for practical use

    Författare :Majid Al-Gburi; Carsten Vogt; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. LÄS MER

  3. 2. Development and Validation of a Numerical Tool for the Aeromechanical Design of Turbomachinery

    Författare :María Angélica Mayorca; Torsten Fransson; Damian Vogt; Eric Seinturier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeromechanical design; turbomachinery; numerical tool; reduced order modeling; mistuning; ROM; aero-structure coupling; CFD; FEM; methods; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : In aeromechanical design one of the major rules is to operate under High Cyclic Fatigue (HCF) margins and away from flutter. The level of dynamic excitations and risk of HCF can be estimated by performing forced response analyses from blade row interaction forces or Low Engine Order (LEO) excitation mechanisms. LÄS MER

  4. 3. The glycobiology of human adenovirus infections : implications for tropism and treatment

    Författare :Naresh Chandra; Niklas Arnberg; Lars Frängsmyr; Gunnel Haldén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; denovirus; cellular receptor; glycosaminoglycan; sialic acid; decoy receptors; tropism; epidemic keratoconjunctivitis; antiviral drugs; GAG-mimetic; obesity; medicinsk virologi; Medical Virology;

    Sammanfattning : Human adenoviruses (HAdVs) are common human pathogens, causing gastrointestinal, ocular, and respiratory infections on a regular basis. Epidemic keratoconjunctivitis (EKC) is a severe ocular infection for which no approved antivirals are available. LÄS MER

  5. 4. Epitaxy of oxide and nitride thin films grown by magnetron sputtering

    Författare :Faezeh Alijan Farzad Lahiji; Per Eklund; Arnaud Le Febvrier; Biplab Paul; Tomas Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The need for electronic devices with new functionalities has caused research to move in a way to design and utilize materials with high-performance thermoelectricity, widely used in batteries, sensors, and electronic devices. Two-dimensional materials (2D) with unique structures and remarkable properties have been identified to fabricate oxide heteroepitaxy. LÄS MER

  7. 5. A Composable and Extensible Environment for Equation-based Modeling and Simulation of Variable Structured Systems in Modelica

    Författare :John Tinnerholm; Adrian Pop; Martin Sjölund; Peter Fritzson; Christopher Rackauckas; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Modeling and Simulation are usually used to solve real-world problems safely and efficiently by constructing digital models of Cyber-Physical Systems. The models can be simulated and analyzed with respect to requirements, and decisions about their design can be based on this analysis. LÄS MER
