  1. 1. Method Development and Analysis of Tensile Stresses in Windscreens : A study on the dynamic stresses on windscreens subjected to random vibrations.

    Master-uppsats, Högskolan i Jönköping/Tekniska Högskolan;

    Författare :Philip Reis; Karthik Murthy; [2018]
    Nyckelord :Dynamic Stresses; FE Method; Laminated Glass; Modal Analysis; Random Vibration; Windscreens;

    Sammanfattning : The thesis work deals with the study and determination of static and dynamic stresses acting on windscreen structures during transportation from the manufacturing site to the production plant. To simulate the stress distribution affected by the transportation, a finite element model of the windscreen is development of the structure and tested. LÄS MER

  2. 2. Petrological characterization of the Cambrian sandstone reservoirs in the Baltic Basin, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Tawonga Chitindingu; [2018]
    Nyckelord :Cambrian; Baltic Basin; porosity; permeability; quartz; cement; Earth and Environmental Sciences;

    Sammanfattning : The Cambrian sandstone reservoirs of the Baltic Basin have been identified by the Geological Survey of Sweden (SGU) as potential CO2 storage sites in line with regulations regarding Carbon Capture and Storage (CCS). In order to understand the petrological and petrophysical characteristics of the sandstone units, 54 thin sections from the three main Cambrian sandstone units were studied. LÄS MER

  3. 3. Undersökning av resonansfenomen i en fläktkonstruktion, med förslag till optimering

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Max Svensson; [2017]
    Nyckelord :Resonance; Natural frequency; Impulse response; Modal analysis; Resonans; Naturliga frekvenser; Impulsrespons; Modalanalys;

    Sammanfattning : Att konstruktioner som innehållande roterande element riskerar att utsättas för resonans är något en konstruktör alltid bör ha i åtanke. Alla konstruktioner har naturliga frekvenser även kallat egenfrekvenser, naturliga rörelsemönster, vars frekvens beror på dess massa och styvhet. LÄS MER

  4. 4. Plasmonic Waveguides : Design and Comparative Study

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Yassin Chowdhury; [2011]
    Nyckelord :;

    Sammanfattning : Although photonics offers an attractive solution to the speed limitation of electronics, reducing the size of bulky photonic components is one of the major issues towards the implementation of photonic integrated circuits. Plasmonic circuits, which tightly confine electromagnetic waves at the metal-dielectric interface, can be a potential solution to this problem. LÄS MER

  5. 5. Impact of degree or Polymerization of Fiber on Viscose Fiber Strength

    Magister-uppsats, Högskolan i Borås/Institutionen Textilhögskolan; Högskolan i Borås/Institutionen Textilhögskolan

    Författare :Shoaib Iqbal; Zuhaib Ahmad; [2011]
    Nyckelord :viscose; viscose fiber; fiber strength; degree of polymerization; dp; regenerated fiber; regenerated cellulose fiber;

    Sammanfattning : The aim of the study was to find out the relationship between the DP and the tensile properties of different regenerated cellulose fibers. During the process to make regenerated cellulose fibers from wood, the reduction in DP of cellulose is a necessary process to enable fiber extrusion. LÄS MER
