  1. 1. Properties of Fe/ZnSe Heterostructures : A Step Towards Semiconductor Spintronics

    Författare :Fredrik Gustavsson; Poul Erik Lindelof; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; semiconductor spintronics Fe ZnSe heterostructures spin injection interface magnetism magnetic tunnel junctions; Fysik; Physics; Fysik; Fysik; Physics;

    Sammanfattning : In the present thesis, the properties at ferromagnet/semiconductor interfaces, relevant for semiconductor spintronics applications, are addressed. Semiconductor spintronics refers to the possibility of storing information using the electron spin, additional to the electron charge, for enhanced flexibility in nanoscale semiconductor devices.

  3. 2. Triboactive Component Coatings : Tribological Testing and Microanalysis of Low-Friction Tribofilms

    Författare :Fredrik Gustavsson; Staffan Jacobson; Bojan Podgornik; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribofilms; low-friction coatings; tungsten disulfide; TEM; Materialvetenskap; Materials Science;

    Sammanfattning : Coatings are often used on critical components in machines and engines to reduce wear and to provide low friction in order to reduce energy losses and the environmental impact.A triboactive coating not only provides this desired performance, it also actively maintains the low friction by a structural or chemical change in a very thin top layer of these already micrometer thin coatings.

  4. 3. Development of soft sensors for monitoring and control of bioprocesses

    Författare :Robert Gustavsson; Carl-Fredrik Mandenius; Johan Hyllner; Carl Johan Franzén; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the manufacture of bio-therapeutics the importance of a well-known process is key for a high product titer and low batch to batch variations. Soft sensors are based on the concept that online sensor signals can be used as inputs to mathematical models to derive new valuable process information. LÄS MER

  5. 4. Towards systematic improvement work in project-based organizations : An efficiency and effectiveness perspective

    Författare :Erik Sundqvist; Diana Chronéer; Fredrik Backlund; Tina Karrbom Gustavsson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Project Management; Project-based organization; Efficiency; Effectiveness; Improvement; Kvalitetsteknik; Quality Technology Management;

    Sammanfattning : Project-based organizations (PBOs) have adopted projects as a primary tool for carrying out most of their operations. By doing so, the PBO operates mainly on two organizational levels, the project level and the organizational level. LÄS MER

  7. 5. Cognitive Behavioral Stress Management Training for Nursing Students

    Författare :Ulrik Terp; Fredrik Hjärthag; Birgitta Bisholt; Petter Gustavsson; Karlstads universitet; []
