  2. 1. Applications of chemometrics in the analysis and characterization of lipids

    Author : Peter Kaufmann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lipids; analysis; Lipider;

    Abstract : The main topics of this thesis are the analysis and characterizationof lipids and applications of chemometrics in this field.The techniques of experimental design, polynomial model building,response surface methods, principal components analysis and partialleast squares regression have been explored and utilized in thedeveopment and optimization of analytical methods.

  4. 2. Cost Optimization of Aircraft Structures

    Author : Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; Farkostteknik;

    Abstract : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. READ MORE

  5. 3. Cost/Weight Optimization of Aircraft Structures

    Author : Markus Kaufmann; Dan Zenkert; Frédéric Lani; KTH; []
    Keywords : Cost Weight Optimization; Weight Penalty; Direct Operating Cost; Composite Structures; Non-destructive testing; Finite element analysis FEA ; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Composite structures can lower the weight of an airliner significantly. The increased production cost, however, requires the application of cost-effective design strategies. Hence, a comparative value is required which is used for the evaluation of a design solution in terms of cost and weight. READ MORE

  6. 4. The evolution of sexual dimorphism and its genetic underpinnings

    Author : Philipp Kaufmann; Elina Immonen; Tim Connallon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sexual conflict; sex-specific dominance; maintenance of genetic variance; sexual antagonism; sex chromosomes; Y haplotypes; artificial selection; sexual dimorphism; Callosobruchus maculatus; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Sexual dimorphism often constitutes the largest phenotypic variance within species but it is puzzling how sexual dimorphisms evolve because most of the genome is shared between the sexes. Sexually antagonistic (SA) selection on a shared genome sets the stage for intralocus sexual conflict. READ MORE

  7. 5. Interfaces in Dye-Sensitized Solar Cells Studied with Photoelectron Spectroscopy at Elevated Pressures

    Author : Susanna Kaufmann Eriksson; Anders Hagfeldt; Håkan Rensmo; Erik Johansson; Joachim Schnadt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitized solar cells; interfaces; solvation; photoelectron spectroscopy; HPXPS; HP-HAXPES; liquid jet; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : With an increasing demand for renewable energy sources, research efforts on different solar cell technologies are increasing rapidly. The dye-sensitized solar cell (DSC) is one such technology, taking advantage of light absorption in dye molecules. READ MORE
