1. 1. Dimensions and projections

   Författare :Anders Nilsson; Peter Wingren; Fredrik Georgsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fractals; Hausdorff dimension; box dimension; packing dimension; projections; MATHEMATICS; MATEMATIK;

   Sammanfattning : This thesis concerns dimensions and projections of sets that could be described as fractals. The background is applied problems regarding analysis of human tissue. One way to characterize such complicated structures is to estimate the dimension. LÄS MER

3. 2. Mathematical Model of the Solid Flow Behavior in a Real Dimension Blast Furnace

   Författare :Reza Safavi Nick; Pär Jönsson; Lage Jonsson; Anders Tilliander; Dong-Yuan Sheng; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A mathematical model based on the continuum mechanic concept has been developed to describe the profile of solid particles in an industrial scale blast furnace. The focus is the in-furnace conditions and its characteristics such as the shape and size of the deadman. LÄS MER

4. 3. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

   Författare :Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

   Sammanfattning : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. LÄS MER

5. 4. Modulating magnetic interactions : in metamaterials and amorphous alloys

   Författare :Nanny Strandqvist; Björgvin Hjörvarsson; Alexei Vorobiev; Sean Langridge; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic metamaterials; interlayer exchange coupling; superlattice; mesospins; magnetic nanostructures; emergence; amorphous alloys; CoAlZr; FeZr; Fysik; Physics;

   Sammanfattning : This thesis is focused on exploring and modulating magnetic interactions in metamaterials and amorphous alloys along one-, two-, and three-dimensions. First, thin films of alternating Fe and MgO are adapted to modulate magnetic interactions along one dimension. LÄS MER
