  1. 6. Quasicrystals : Classification, diffraction and surface studies

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Elisabet Edvardsson; [2015]
    Keywords : quasicrystal; cohomology of groups; reduced lattice; diffraction; X-ray standing waves;

    Abstract : Quasicrystal is the term used for a solid that possesses an essentially discrete diffraction pattern without having translational symmetry. Compared to periodic crystals, this difference in structure gives quasicrystals new properties that make them interesting to study -- both from a mathematical and from a physical point of view.

  3. 7. Improving green LEDs: A meta study into the causes and remedies of the green gap

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Andreas Malmgren; [2015]
    Keywords : Light emitting diodes; quantum wells; recombination rate; Technology and Engineering; Physics and Astronomy;

    Abstract : This literature review investigates and evaluates different strategies to improve InGaN-based light emitting diodes (LED) by analyzing published theoretical and experimental studies. The issues of non-uniform carrier distribution, piezoelectric polarization fields and poor wave function overlap can be mitigated by the use of InGaN barriers and substrates as well as staircase designs for quantum wells (QW).

  4. 8. A Computational Model for Fracture Healing Integrated with Mechanical Stimulation and Growth Factors

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Cassandra Jernberg; [2014]
    Keywords : Computational modelling; Non-union bone fracture; Fracture healing; Growth factors; BMP-2; rhBMP-2; Mechanical loading; FEM;

    Abstract : Non-union bone fractures are a standing problem for clinical treatments. It has been found that the exogenous growth factor recombinant human bone morphogenetic protein-2 (rhBMP-2) induces bone healing in potential non-union fractures. However, the currently used clinical dose of rhBMP-2 is high and causes side-effects. READ MORE

  5. 9. Implementation of an industrial process control interface for the LSC11 system using Lattice ECP2M FPGA

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Parthasarathy Murali Baskar Rao; [2012]
    Keywords : PCI Express PCIe ; Lattice ECP2M ECP2M ; Field Programmable Gate Arrays FPGA ;

    Abstract : Reconfigurable devices are the mainstream in today’s system on chip solutions. Reconfigurable devices have the advantages of reduced cost over their equivalent custom design, quick time to market and the ability to reconfigure the design at will and ease. One such reconfigurable device is an FPGA. READ MORE
