  1. 1. Robust Design Experimentation and Dispersion Effects

    Författare :Martin Arvidsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; estimation procedure; design of experiments; generalized linear models; event matrices; variance component; location effects; split-plot experiments; robust design; identification procedure; dispersion effects;

    Sammanfattning : One of the most common methods in robust design methodology is design of experiments. This method makes it possible to identify settings of design factors that make products and production processes robust with respect to noise factors. LÄS MER

  3. 2. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

    Författare :Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

    Sammanfattning : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. LÄS MER

  4. 3. Analysis of Dispersion Effects in Unreplicated Factorial Designs

    Författare :Kerstin Wiklander; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :dispersion effects; location effects; two-level factorial experiment; fractional designs; Hadamard products; fractional designs;

    Sammanfattning : Methods for estimating and testing hypotheses of dispersion effects in two-level unreplicated factorial designs are studied. Under a particular = normal model, some linear combinations of the response variables are constructed in order to make a simple inference. LÄS MER

  5. 4. InP-based photonic crystals : Processing, Material properties and Dispersion effects

    Författare :Audrey Berrier; Srinivasan Anand; Alfred Forchel; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Photonic crystals; indium phosphide; photonic bandgap; Bloch modes; slow light; dispersion; coupled cavity waveguides; chemically assisted ion beam etching; lag effect; cavities; optical losses; carrier transport; carrier lifetimes; negative refraction; photonic bandstructure; Physics; Fysik;

    Sammanfattning : Photonic crystals (PhCs) are periodic dielectric structures that exhibit a photonic bandgap, i.e., a range of wavelength for which light propagation is forbidden. The special band structure related dispersion properties offer a realm of novel functionalities and interesting physical phenomena. LÄS MER

  7. 5. Changing population distribution in Sweden : long term trends and contemporary tendencies

    Författare :Johan Håkansson; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Population distribution; redistribution; Sweden; geographical levels; concentration; dispersion; accessibility; migration; natural population change; age composition; Population Distribution; Concentration; Dispersion; Accessibility; Migration; Natural increase;

    Sammanfattning : The aim of the thesis is to describe and analyse the population redistribution in Sweden at different geographical levels from the beginning of the 19th century to the end of the 20th century. The analysis is approached in three different ways. First, the redistribution at different geographical levels is analysed (papers I and II). LÄS MER
