  1. 1. Tactile Perception - Role of Physical Properties

    Detta är en avhandling från Stockholm : KTH

    Författare :Lisa Skedung; KTH.; [2010]
    Nyckelord :MEDICIN; MEDICINE; Finger Friction; Skin Friction; Paper Friction; Friction Coefficient; Piezoelectric Force Sensor; Skin Tribology; Biotribology; Soft Tribology; Surface Roughness; Profilometry; Coated Paper; Uncoated Paper; Printing Paper; Magazine Paper; Tactile Perception; Psychophysics; Multidimensional Scaling; Magnitude Estimation; Paper Coarseness; Thermal Conductivity; X-ray Photoelectron Spectroscopy.;

    Sammanfattning : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. LÄS MER

  5. 4. On Heat and Paper : From Hot Pressing to Impulse Technology

    Detta är en avhandling från Stockholm : Fiber- och polymerteknologi

    Författare :Marco Francesco Carlo Lucisano; KTH.; [2002]
    Nyckelord :Paper; Impulse Drying; Heat Transfer; Phase Change; Heat-Pipe Effect; Delamination; Flashing;

    Sammanfattning : Impulse technology is a process in which water is removedfrom a wet paper web by the combined action of mechanicalpressure and intense heat. This results in increased dewateringrates, increased smoothness on the roll side of the sheet, andincreased density. LÄS MER

  7. 5. Modelling and simulation of paper structure development

    Detta är en avhandling från Sundsvall : Department of Natural Sciences, Engineering and Mathematics, Mid Sweden University

    Författare :Stefan Lindström; Mittuniversitetet.; [2008]
    Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; Forming; Fibre; Paper; Fibre suspension; Paper structure; Simulation; Rheology;

    Sammanfattning :      A numerical tool has been developed for particle-level simulations of fibre suspension flows, particularly forming of the fibre network structure of paper sheets in the paper machine. The model considers inert fibres of various equilibrium shapes, and finite stiffness, interacting with each other through normal, frictional, and lubrication forces, and with the surrounding fluid medium through hydrodynamic forces.
