  1. 6. Characterization of some natural and synthetic materials with silicate structures

    Författare :Edwin Escalera; Farid Akhtar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Engineering Materials; Materialteknik; Engineering Materials;

    Sammanfattning : The present thesis deals with characterization of silicate structures with a determined morphology and structure such as ordered mesoporous silica and layered silicates. Mesoporous silica groups are amorphous solids exhibiting highly ordered pore structures with narrow pore size distributions and large surface areas. LÄS MER

  3. 7. Tribological behaviour of polymers in lubricated contacts

    Författare :Arash Golchin; Klaus Friedrich; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : An important issue in hydropower and other industries is the increasing demand for introduction of environment friendly solutions. Mineral oil based lubricants have long been used in various sliding bearings in hydropower stations. LÄS MER

  4. 8. Kurt Lewins metod Kraftfältsanalys i teori och praktik : En fallstudie av ett organisationsutvecklingsuppdrag på en akademisk teknisk institution

    Författare :Ulf Grundel; Siv Boalt Boethius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Man Machine Relation Focusing Gender; Människa-maskin med inriktning mot genusforskning; Genus och teknik; Gender and Technology;

    Sammanfattning : Denna licentiatsuppsats beskriver ett förändringsarbete inom ramen för ett organisationsutvecklingsuppdrag på en akademisk teknisk institution. Bakgrunden till uppdraget var ett behov av förändring och utveckling av institutionens arbetsformer avseende ledarskap, samarbete och samspel. Min uppdragsgivare var institutionsledningen. LÄS MER

  5. 9. Secure emergency communications of emergency responders : a case study of Kemi municipality in Finland

    Författare :Heidi Hartikainen; Erik Borglund; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emergency management; information security; emergency response; emergency communications; secure communications; Data- och systemvetenskap; Computer and Systems Science;

    Sammanfattning : Emergency response is highly time-critical and information dependent: every moment counts and organizations need to access various information that supports their decision making and informs them about the scale and location of the emergency, the damages, and the availability of human and physical resources. This kind information can originate from many different places and the situation can be stressful as there is a need to communicate quickly, reliably and accurately within their own organization, but also inter-organizationally.

  7. 10. Damage evolution in laminates with manufacturing defects

    Författare :Yongxin Huang; Kristofer Gamstedt; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : In this thesis, experimental investigations and theoretical studies on the stochastic matrix cracking evolution under static loading in composite laminates with manufacturing defects are presented. The presented work demonstrates a methodology that accounts for the statistically distributed defects in damage mechanics models for the assessment of the integrity of composites and for the structural design of composites.
