  1. 16. Interaction between pellet properties and blast furnace operation

    Författare :Ulrika Leimalm; Gabriella Tranell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : The raw material properties of iron-bearing material and coke have a significant impact on the blast furnace (BF) process. The raw materials are designed and chosen to achieve smooth BF operation but the operational parameters can be simultaneously modified to meet properties of selected raw materials. As the pre-set process conditions change, e. LÄS MER

  3. 17. Depth Map Upscaling for Three-Dimensional Television : The Edge-Weighted Optimization Concept

    Författare :Sebastian Schwarz; Mårten Sjöström; Atanas Gotchev; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3d video; 3DTV; video coding; capture; distribution; EWOC; depth map upscaling; time-of-flight;

    Sammanfattning : With the recent comeback of three-dimensional (3D) movies to the cinemas, there have been increasing efforts to spread the commercial success of 3D to new markets. The possibility of a 3D experience at home, such as three-dimensional television (3DTV), has generated a great deal of interest within the research and standardization community. LÄS MER

  4. 18. Selective Comminution Applied to Mineral Processing of Critical Metals

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; selective comminution; compressive crushing; analytical method; minerals; critical metals; elements.;

    Sammanfattning : The outstanding properties of tungsten and tantalum make them valuable metals and, in some cases, irreplaceable in applications. Due to the vital economic importance and limited supply, growing interest places these metals on the critical metals risk list. LÄS MER

  5. 19. Thermal Conductivity of Materials under Conditions of Planetary Interiors

    Författare :Zuzana Konôpková; Peter Lazor; Vitali Prakapenka; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; high pressures-high temperatures; thermal conductivity; diamond anvil cell; laser-heating; planetary cores; Earth sciences; Geovetenskap;

    Sammanfattning : The presented thesis focuses on study of transport and thermoelastic properties of materials under conditions of planetary interiors by means of high-pressure experimental tools and finite element modeling, and their role in the dynamics and states of cores of terrestrial planets. Experiments in laser-heated diamond anvil cell (LHDAC) in combination with numerical simulations of heat transfer in DAC are shown to yield information on thermal conductivity of a pressurized sample.
