    Sammanfattning : Nowadays, cameras are everywhere thanks to the tremendous progress on sensor technology. However, their performance is far away from what we experience by our eyes. LÄS MER

  3. 2. Distance Functions and Image Processing on Point-Lattices : with focus on the 3D face- and body-centered cubic grids

    Författare :Robin Strand; Gunilla Borgefors; Stina Svensson; Christer Kiselman; David Coeurjolly; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computerized image analysis; digital geometry; distance functions; non-standard grids; point-lattices; Image analysis; Bildanalys;

    Sammanfattning : There are many imaging techniques that generate three-dimensional volume images today. With higher precision in the image acquisition equipment, storing and processing these images require increasing amount of data processing capacity. Traditionally, three-dimensional images are represented by cubic (or cuboid) picture elements on a cubic grid. LÄS MER

  4. 3. Sublimation Growth of 3C-SiC : From Thick Layers to Bulk Material

    Författare :Valdas Jokubavičius; Mikael Syväjärvi; Rositsa Yakimova; Didier Chaussende; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Silicon carbide (SiC) is a semiconductor material which holds high promises for various device applications. It can be obtained in different crystal structures called polytypes. The most common ones are hexagonal (6H- and 4H-SiC) and cubic (3C-SiC) silicon carbide. LÄS MER

  5. 4. Pressure-Induced Amorphization and Distinct Amorphous States of Clathrate Hydrates

    Författare :Paulo H. B. Brant Carvalho; Ulrich Häussermann; Ove Andersson; John Stephen Loveday; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Clathrate Hydrates; Pressure-Induced Amorphization; Amorphous States; Glassy States; Ice; Neutron Diffraction; Klatrathydrater; Tryckinducerad Amorfisering; Amorfa tillstånd; Glasartade tillstånd; Is; Neutrondiffraktion; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : This thesis summarizes a study on the pressure-induced amorphization (PIA) and structures of amorphous states of clathrate hydrates (CHs).PIA involves the transition of a crystalline material into an amorphous solid in response of mechanical compression at temperatures well below the melting point.

  7. 5. Development and applications of theoretical algorithms for simulations of materials at extreme conditions

    Författare :Igor Mosyagin; Igor Abrikosov; Sergey Simak; Andrei Postnikov; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Materials at extreme conditions exhibit properties that differ substantially from ambient conditions. High pressure and high temperature expose anharmonic, non-linear behavior, and can provoke phase transitions among other effects. Experimental setups to study that sort of effects are typically costly and experiments themselves are laborious. LÄS MER
