    Sammanfattning : Minerals in Earth’s crust and suspended in the atmosphere form water or ice films as thin as a few nanometers to as thick as a few micrometers, and beyond. Mineral-bound water and ice films in terrestrial systems (e.g. LÄS MER

  3. 17. Imprecise information in multi-level decision trees

    Författare :Jim Johansson [Idefeldt]; Love Ekenberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi-level; decision tree; decision analysis; decision tool; imprecise; Computer science; Datavetenskap;

    Sammanfattning : The information available to decision makers is often vague and imprecise, and various methods based on interval estimates of probabilities and utilities have been proposed to deal with this. The discussion has, however, mostly evolved around representation, and much less has been done to take into consideration the evaluation, and also computational and implementation aspects has been left out.

  4. 18. Wafer-level heterogeneous integration of MEMS actuators

    Författare :Stefan Braun; Göran Stemme; Martin A. Schmidt; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microelectromechanical systems; MEMS; silicon; wafer-level; integration; heterogeneous integration; transfer integration; packaging; assembly; wafer bonding; adhesive bonding; eutectic bonding; release etching; electrochemical etching; microvalves; microactuator; Shape Memory Alloy; SMA; NITINOL; TiNi; NiTi; cold-state reset; bias spring; stress layers; crossbar switch; routing; switch; switch array; electrostatic actuator; S-shaped actuator; zipper actuator; addressing; transfer stamping; blue tape; Computer engineering; Datorteknik;

    Sammanfattning : This thesis presents methods for the wafer-level integration of shape memory alloy (SMA) and electrostatic actuators to functionalize MEMS devices. The integration methods are based on heterogeneous integration, which is the integration of different materials and technologies. LÄS MER

  5. 19. Development of competence in biochemical experimental work : Assessment of complex learning at university level

    Författare :Christina Bergendahl; Lena Tibell; Lisbeth Lundahl; Lars-Owe Dahlgren; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teaching; experimental work; laboratory based project work; open experiments; biochemistry; life science; university level; action research; course design; aims and objectives; assessment; formative assessment; competence; complex learning; Didaktik; Subject didactics; Ämnesdidaktik; biokemi; Biochemistry;

    Sammanfattning : Biochemistry is part of life science: a fast developing multidisciplinary area. The overall aims of this thesis and the work underlying it were to find ways in which to develop competence in biochemistry at university level and to assess complex learning. A particular interest was the development of experimental work as a means to promote learning. LÄS MER

  7. 20. Problemlösningsarbete på låg organisatorisk nivå : Två studier om implementering respektive konkretisering av idéer om kundorderstyrd tillverkning

    Författare :Gun Abrahamsson; Sven Helin; Nils Kinch; Ingemund Hägg; Thomas Sandberg; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; Företagsekonomi; Industriell organisation; Institutionell teori; Organisatoriskt lärande; Regelstyrd handling; Ekonomistyrning; Lateralt samarbete; Fallstudier; World Class Manufacturing; Ständig förbättring; Business studies; Företagsekonomi; Business Studies;

    Sammanfattning : The two studies reported in this thesis are about problem solving at a low organisational level in an organisational unit in a Swedish manufacturing company, which has adopted ideas of World Class Manufacturing. In the first study, we analyse, from an organisational learning perspective, the implementation of the well-known concept Continuous Improvement at shop-floor level and how management accounting may facilitate or impede improvement work.
