  1. 1. Mapping the concept of industrialized bridge construction : potentials and obstacles

    Författare :Johan Larsson; Christina Claeson-Jonsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Improving productivity is a central challenge in most industries and so also in construction. In many countries, such as Great Britain and US (Egan, 1998; Huang et al., 2009; Teichholz, 2001), governmental reports and research publications have highlighted the slow growth of productivity in the construction industry.

    Sammanfattning : Since the 1970's the union movement has regarded international business as a threat to union interests, democratic values and national independence. The union movement has mentioned two methods of defence against influence of international businesses: to introduce societal restrictions on a national or international level and to establish international (corporate) group unions.

  4. 3. Innovation as Creative Response. Determinants of Innovation in the Swedish Manufacturing Industry, 1970-2007

    Författare :Josef Taalbi; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; creative response; structural change; development blocks; transformation pressure; industrial transformation; manufacturing industry; Sweden;

    Sammanfattning : This doctoral thesis examines the driving forces of product innovations in the Swedish manufacturing industry during the period 1970-2007. Specifically it examines whether and how innovations have been the creative response to positive factors, such as new opportunities and obstacles related to their exploitation, and negative factors, such as economic, environmental and organizational problems.

  5. 4. High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties

    Författare :Markus Peterson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-storey residential buildings; Structural frames; SCC; Self-compacting concrete; High-performanceconcrete; HPC; Concrete; Building materials; Cast in-situ concrete;

    Sammanfattning : Cast in-situ concrete is the most frequently used materials technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. LÄS MER

  7. 5. Approximation of topology optimization problems using sizing optimization problems

    Författare :Anton Evgrafov; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; structural optimization; bilevel programming; approximation; topology optimization; control in coefficients; optimal design; fictitious domain; control in coefficients;

    Sammanfattning : The present work is devoted to approximation techniques for singular extremal problems arising from optimal design problems in structural and fluid mechanics. The thesis consists of an introductory part and four independent papers, which however are united by the common idea of approximation and the related application areas. LÄS MER
