  1. 1. The Use of 2D and 3D Displays in Military Settings

    Författare :Patrik Lif; Leo Poom; Kip Smith; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; visuell perception; 3D; displays; spatial cues; Psychology; Psykologi;

    Sammanfattning : The purpose of this thesis is to evaluate the possibilities of using 3D perspective displays in different military settings, and to illustrate the limitations of 3D displays, that is, when 2D displays are to be preferred. More specifically, this thesis explores (a) readability during vibrations, (b) perception aspects on perspective aircraft displays, and (c) the value of spatial cues in 3D air traffic displays in military settings.

    Nyckelord :EU; collective security; use of force; multilateralisation of intervention; regional security provider; local actors; resource factors; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Peace and Conflict Research; Freds- och konfliktforskning;

    Sammanfattning : The EU has since 2003 carried out six military operations.  This thesis seeks to determine the circumstances under which the EU will, or will not, undertake military operations. LÄS MER

  3. 3. Bringing System Dynamics into Action Research

    Författare :Paul Holmström; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; process consultation; Operations Research; simulation; action research; modelling; System Dynamics; healthcare;

    Sammanfattning : System Dynamics simulation is a computer-aided approach to policy analysis and design, often carried out by external experts in simulation. System Dynamics is particularly useful in complicated and complex situations, such as healthcare. However, research has shown that few models in healthcare are implemented. LÄS MER

  5. 5. Aspects of optimizing pulp fibre properties for tissue and packaging materials

    Författare :Hafizur Rahman; Armando Cordova; Per Engstrand; Börje Norlin; Göran Bengtsson; Mittuniversitetet; []

    Sammanfattning : To improve the competitive advantages of pulp fibre-based materials for tissue and packaging over fossil-based products, it is essential to increase knowledge of the selectivity of the cooking and the chemimechanical processes by optimizing the unit operations of impregnation, cooking and refining. A general goal in pulping processes is to achieve as efficient and even fibre separation as possible. LÄS MER
