  1. 6. Essays on expectations and financial markets

    Författare :Staffan Lindén; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Survey; Inflation; Expectations; Perceptions; Rational; Inattentive; Event study; Option introduction; Stock market; Asset pricing; Price effect; Risk effect; Derivatives;

    Sammanfattning : This thesis is a collection of three empirical papers that tests hypotheses within the context of two related and intersecting theoretical frameworks: rational expectations and efficient markets. The aim is to empirically explore to what extent households form their inflation expectations in a rational manner, and to explain why households’ perceptions may deviate from the measured official rate.

  3. 7. Photoelectron spectroscopic studies of deposited metal clusters and model catalyst systems

    Författare :Staffan Andersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Metal clusters are small metal aggregates between atomic and metal systems. Their physical and chemical properties have been observed to change with size. Their surface fraction is large which makes them of particular interest for catalysis. Most presently used catalyst systems consist of small metal particles on porous oxide supports. LÄS MER

  4. 8. Theory and Reality : Metaphysics as Second Science

    Författare :Staffan Angere; Teoretisk filosofi; []
    Nyckelord :HUMANIORA; HUMANITIES; necessitation; semantics; categories; Theory; metaphysics;

    Sammanfattning : Theory and Reality is about the connection between true theories and the world. A mathematical framefork for such connections is given, and it is shown how that framework can be used to infer facts about the structure of reality from facts about the structure of true theories, The book starts with an overview of various approaches to metaphysics.

  5. 9. On dynamic array processing for GNSS software receivers

    Författare :Staffan Backén; Gonzalo Seco Granados; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : This thesis presents contributions in the field of satellite navigation with a focus on array processing and related implementation issues. For readers not familiar with GNSS, it also includes a brief overview of satellite navigation.Compared to the state of the art only ten years ago, modern GNSS receivers are very capable. LÄS MER

  7. 10. Towards dynamic array processing for GNSS software receivers

    Författare :Staffan Backén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Since the very first Global Positioning System satellite was launched in 1978, Global Navigation Satellite Systems (GNSS) have developed into a world wide utility, providing everyone with an affordable method for determining accurate position and time. However, the system is susceptible to multipath (when the signal is reflected off a surface), interference (other signals in the same frequency band) and attenuation (for example canopies blocking some of the signal energy).
