  4. 2. Shoulder-neck exposure from assembly work and the significance of rationalization

    Author : Shihan Bao; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Abstract : The main purpose of this thesis was to investigate the implications of different rationalization levels of assembly work on shoulder-neck exposure. Three levels were studied: (1) a Chinese Tayloristic system, (2) a Swedish Tayloristic system, and (3) an assembly workplace rationalization in Sweden according to 'modern' rationalization principles including ergonomic purposes.

  5. 3. Some modes of convergence and their application to homogenization and optimal composites design

    Author : Anders Holmbom; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Homogenization; two-scale convergence; MATHEMATICS; MATEMATIK; Mathematics;

    Abstract : In this thesis, we develop, extend, apply, and discuss a number of methods for the study of limits of sequences of functions and operators. The connection between the notion of two-scale convergence and more general concepts of convergence is investigated and some alternative classes of admissible test functions are characterized.

  6. 4. Erosion of rock with a water jet

    Author : Göran Rehbinder; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : During the last decade destruction of rock with the aid of a high speed water jet has been the subject of great interest. Most papers published in this field deal with experiments but very little has been done theoretically. READ MORE

  7. 5. Why do rodent populations fluctuate? : stability and bifurcation analysis of some discrete and continuous predator-prey models
