  1. 1. Exploiting reciprocal space : Electron diffraction, textures and precession

    Författare :Peter Oleynikov; Sven Hovmöller; Xiaodong Zou; Jean-Paul Morniroli; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; electron diffraction; texture patterns; precession electron diffraction; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Electron crystallography emerges as a new tool for accurate structure determination of very small crystals. In order to exploit the full potential of electron diffraction, the methods for data acquisition and processing have to be developed towards the high standards of X-ray crystallography. LÄS MER

  3. 2. Efficient mineral liberation – Multidimensional investigation of mechanical stress and ore texture

    Författare :Parisa Semsari Parapari; Jan Rosenkranz; Mehdi Parian; Hakan Benzer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Loading mechanism; Ore texture; Breakage mode; Fracture energy; Fragmentation; Breakage mechanism; Statistical analysis; 3D Deformation; Crack quantification; Mineral Processing; Mineralteknik;

    Sammanfattning : Within mineral comminution, the product properties (such as particle size distribution and mineral liberation characteristics) along with process efficiency are affected by material related and process environment factors. Understanding and optimizing these factors leads to designing and developing an energy-efficient process with a specified product. LÄS MER

  4. 3. Development of a geometallurgical testing framework for ore grinding and liberation properties

    Författare :Abdul-Rahaman Mwanga; Jan Rosenkranz; Hakan Benzer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grindability test; mineral texture; breakage properties; mineral liberation; process modeling; geometallurgy; Mineral Processing; Mineralteknik;

    Sammanfattning : Efficient measurement methods for comminution properties are an important prerequisite for testing the variability of an ore deposit within the geometallurgical context. This involves the investigation of effects of mineralogy and mineral texture on the breakage of mineral particles. LÄS MER

  5. 4. Rye bread in Sweden : Health-related and sensory qualities, consumer perceptions and consumption patterns

    Författare :Pernilla Sandvik; Margaretha Nydahl; Iwona Kihlberg; Ingela Marklinder; Hely Tuorila; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; national dietary survey; sensory analysis; preference mapping; sourdough; whole grain; public health; health promotion; Kostvetenskap; Food; Nutrition and Dietetics;

    Sammanfattning : Rye bread has shown potential as a health-beneficial component in the diet, especially in relation to non-communicable diseases. To have a beneficial effect in reality, however, it also needs to be available, chosen and eaten. Less research has focused on rye bread from a consumer perspective. LÄS MER

  7. 5. Evaluating and Improving Rendered Visual Experiences : Metrics, Compression, Higher Frame Rates & Recoloring

    Författare :Pontus Ebelin; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Graphics; Image Quality Assessment; Perception; Edge Detection; Low Dynamic Range Imagery; High Dynamic Range Imagery; High Frame Rates; Texture Compression; Color Vision Deficiency; Recoloring; Computer Graphics; Image Quality Assessment; Perception; Edge Detection; Low Dynamic Range Imagery; High Dynamic Range Imagery; High Frame Rates; Texture Compression; Color Vision Deficiency; Recoloring;

    Sammanfattning : Rendered imagery is presented to us daily. Special effects in movies, video games, scientific visualizations, and marketing catalogs all often rely on images generated through computer graphics. However, with all the possibilities that rendering offers come also a plethora of challenges. LÄS MER
