  1. 1. Om organiserad komplexitet : integration av organisering, lärande och kunnande

    Författare :Sören Augustinsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Sammanfattning : The overall purpose of the thesis is how organisations can be understood according their own conditions instead of trying to make them more rational and structured than they actually are in practice. In order to accomplish this, the thesis includes theoretical discussions with support in the following central concepts: organisation, learning and knowing. LÄS MER

  2. 2. Experimental and numerical studies of intralaminar cracking in high performance composites

    Författare :Mohamed Sahbi Loukil; Janis Varna; Zoubir Ayadi; Constantinos Soutis; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : The macroscopic failure of composite laminates subjected to tensile increasing load is preceded by initiation and evolution of several microdamage modes. The most common damage mode and the one examined in this thesis is intralaminar cracking in layers. LÄS MER

  3. 3. On Monitoring and Control of Machining Processes

    Författare :Mikael Bäckström; Anders Kinnander; Thomas Lundholm; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing engineering; Produktionsteknik; Manufacturing Systems Engineering;

    Sammanfattning : The thesis presents several aspects related to the industrial and academic activities associated with monitoring and control of the machining process and machine tools A survey of the industrial situation identified some key factors for a successful implementation of monitoring and control techniques. Applicable, relatively simple, systems for cutting-process monitoring and adaptive control are available on the commercial market today but the degree of industrial utilisation of the technique is low because the systems are experienced as hard to operate and use, and are at the same time considered unreliable.

  4. 4. On crack growth under compressive stresses

    Författare :Per Isaksson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ph.D. Thesis; Fracture mechanics; Cellulose and paper engineering; Cellulosa- och pappersteknik; Hållfasthetslära;

    Sammanfattning : This thesis concerns fractures subjected to compressive stresses. In the four papers appended fracture behavior in brittle as well as ductile materials is studied. LÄS MER

  5. 5. Technology, Language and Thought : Extensions of Meaning in the English Lexicon

    Författare :Marlene Johansson Falck; Ulf Magnusson; Dirk Geeraerts; Luleå tekniska universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive linguistics; cognitive tools; language; English; sense development; meaning extension; thought; metaphors; metonymies; scaffoldings; entrenchment; technology; electricity; steam engines; motor vehicles; roads; ways; Languages and linguistics; Språkvetenskap; English; engelska; Engelska med didaktiskt inriktning;

    Sammanfattning : In this thesis, the relationship between technological innovation and the development of language and thought is analysed. For this purpose, three different fields of technology are investigated: 1) the steam engine, 2) electricity, and 3) motor vehicles, roads and ways. LÄS MER
