  1. 1. Cost/Weight Optimization of Aircraft Structures

    University dissertation from Stockholm : KTH

    Author : Markus Kaufmann; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  2. 2. Cost Optimization of Aircraft Structures

    University dissertation from Stockholm : KTH

    Author : Markus Kaufmann; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik 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

  3. 3. Synthetic studies of rigid tetracyclic oxanorbornanes. Regioselective reductive Heck arylation of a tetracyclic scaffold

    University dissertation from Organic Chemistry, Lund University

    Author : Andreas Wållberg; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; oxanorbornane; rigid; Heck-reaction; regioselective; Organisk kemi;

    Abstract : Rigid or conformationally restricted compounds are intresting from a pharmacological point of view since they do not have to pay the entropy penalty paid by more flexible molecules in binding to e.g. a protein. READ MORE

  4. 4. Vibro-acoustic modelling of anisotropic poroelastic materials characterisation of the anisotropic properties

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Christophe Van der Kelen; KTH.; KTH.; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present-day challenges in the transport industry, steered by the increasing environmental awareness, necessitate manufacturers to take measures to reduce emissions related to the movements of goods and humans. In particular, the measures aiming at a reduced mass or higher load capacity to increase fuel efficiency,  generally deteriorate the noise and vibration insulation properties of their products.

  5. 5. Short- and Long-Term Influences of Education, Health Indicators, and Crime on Labor Market Outcomes Five Essays in Empirical Labor Economics

    University dissertation from Linköpiing : Linköping University Electronic Press

    Author : Elisabeth Lång; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; health indicators; crime; labor market outcomes; family background; twins; field experiments;

    Abstract : The objective of this thesis is to improve the understanding of how several individual characteristics, namely education (years of schooling), health indicators (height, weight, smoking, alcohol consumption, and exercise), criminal behavior, and crime victimization, influence labor market outcomes in the short and long run. The first part of the thesis consists of three studies in which I adopt a within-twin-pair difference approach to analyze how education, health indicators, and earnings are associated with each other over the life cycle.
