  1. 16. Peacemaking Up Close : Explaining Mediator Styles of International Mediators

    Författare :Mathilda Lindgren; Desirée Nilsson; Anders Themnér; Kyle Beardsley; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mediator; mediation; mediator style; negotiation; armed conflict; peace; IGO; NGO; survey experiment; interviews; Peace and Conflict Research; Freds- och konfliktforskning;

    Sammanfattning : Scholarly work on international mediation suggests that how third parties mediate influences the resolution of armed conflicts. However, our understanding of what explains mediator style is limited. This dissertation addresses this gap by offering the first systematic study on explanations for mediator styles at the level of the individual. LÄS MER

  3. 17. Computational Studies of Magnetohydrodynamic Stability for Reversed-Field Pinches and Tokamaks

    Författare :Donghui Liu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This work describes the ideal & resistive Magnetohydrodynamic (MHD) stability properties of Tokamak and Reversed-Field Pinch (RFP) plasmas. The first four papers are concerned with the cylindrical approximation of RFPs and tokamaks whereas the final two papers deal with a fully toroidal description. LÄS MER

  4. 18. Modification of Float Glass Surfaces by Ion Exchange

    Författare :Stefan Karlsson; Bo Jonson; Helmut Schaeffer; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion exchange; float glass; surface modification; surface colour; flexural strength; Glasteknologi; Glass Technology;

    Sammanfattning : Glass is a common material in each person’s life, e.g. drinking vessels, windows, displays, insulation and optical fibres. By modifying the glass surface it is possible to change the performance of the entire glass object, generally known as Surface Engineering. LÄS MER

  5. 19. Inversion of Magnetotelluric Data Constrained by Borehole Logs and Reflection Seismic Sections

    Författare :Ping Yan; Thomas Kalscheuer; Laust Pedersen; Maria Garcia Juanatey; Andreas Junge; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetotellurics; constrained inversion; borehole logs; seismic; COSC; Alnö alkaline and carbonatite; airborne VLF; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : This thesis presents two new algorithms for doing constrained Magnetotelluric (MT) inversion based on an existing Occam 2D inversion program. The first algorithm includes borehole resistivity logs as prior information to constrain resistivity directly in the vicinity of boreholes. LÄS MER

  7. 20. Non-destructive measurement of near-surface cracks in railheads : with focus on ultrasonic inspections

    Författare :Rayendra Anandika; Jan Lundberg; Paul Wilcox; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail inspection; phased array; ultrasonic testing; eddy current testing; surface cracks; non-destructive testing; NDT; railway; condition monitoring; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Near-surface cracks in railhead that caused by rolling contact fatigue (RCF) is one of a kind rail defects that degrade rail track quality. Dependent on the trail load, the cracks can reach to severe level quickly. LÄS MER
