  2. 16. Micro-Structure Modelling of Acoustics of Open Porous Material

    Author : Eva Lundberg; Peter Göransson; Per Wennhage; Ulf Orrenius; Camille Perrot; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; porous material; flow resistivity; micro-structure; anisotropic; foam; strut; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Transportation is a large and growing part of the world’s energy consumption. This drives a need for reduced weight of rail vehicles, just as it does for road vehicles. In spite of weight reductions, the vehicle still has to provide the same level of acoustic comfort for the passengers. READ MORE

  4. 17. Numerical homogenization of network models and micro-mechanical simulation of paperboard

    Author : Morgan Görtz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; domain decomposition; paper model; local orthogonal decomposition; Bending; paper simulation; network model; multiscale;

    Abstract : Micro-mechanical simulations of paper products involve complex geometries and challenging numerical problems. This work considers micro-mechanical simulations where individual paper fibers are modeled and resolved. This level of detail is useful in paper-product development, where wood composition and other fiber-based parameters are essential. READ MORE

  5. 18. Turbulence measurements in fiber suspension flows : experimental methods and results

    Author : Monika Carina Fällman; Fritz Bark; Daniel Söderberg; Fredrik Lundell; Thomas Wikström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid; flow; turbulent; turbulence; paper; pulp; fiber; fibre; suspension; two-phase; experimental; conductivity; micro-probes; passive scalar; ultrasonic; Doppler shift; Fluid mechanics; Strömningsmekanik;

    Abstract : Turbulent mixing is present in many pulp and paper processes. It is a particularly important factor in the design and improvements of the paper machine headbox, influencing the final paper structure. READ MORE

  6. 19. Mechanical analyses of trabecular bone and its interaction with implants

    Author : Dan Wu; Cecilia Persson; Hanna Isaksson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; Elastic modulus; Digital volume correlation; Pullout resistance; Micro-computed tomography.;

    Abstract : Bone substitute materials or implants are commonly used in the surgical treatment of bone fractures. However, severe complications are sometimes reported. READ MORE

  7. 20. Airway mechanics of mice and men

    Author : Lennart Lundblad; Malmö Klinisk fysiologi och nuklearmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; radiologi; tomografi; tomography; medical instrumentation; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; Penh; emphysema; airway resistance; gas conditioning; plethysmography; lung mechanics; Boyle s law; Physiology; medicinsk instrumentering; Klinisk fysiologi; radiology; enhanced pause; pulmonary fibrosis; micro computed tomography; forced oscillation technique; COPD;

    Abstract : In this thesis we explore and further develop several techniques used in the animal laboratory as well as in the clinical setting. In particular, we expand the understanding and usefulness of plethysmographic techniques in small rodents. READ MORE
