  2. 2. A Harmonic-Oscillator Design Methodology Based on Describing Functions

    Författare :Jesper Bank; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oscillator design efficiency; phase noise; impulse sensitivity function; design methodology; amplitude control; frequency tuning; oscillator; describing function;

    Sammanfattning : Oscillators are present in most electronic equipment where they provide timing information, for example as sampling clocks in analog-to-digital converters or as radio carriers in wireless communications. To design an oscillator, we must have knowledge of the properties and the operation of oscillators. LÄS MER

  3. 3. Amoebas, Discriminants, and Hypergeometric Functions

    Författare :Lisa Nilsson; Mikael Passare; Maurice Rojas; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; amoeba; coamoeba; discriminant; hypergeometric functions; Mellin transform; Algebra; geometry and mathematical analysis; Algebra; geometri och analys; matematik; Mathematics;

    Sammanfattning : This thesis consists of six chapters. In Chapter 1 we give some historical background to the topic of the thesis together with the fundamental definitions and results that the thesis is based on. In Chapter 2 we study Mellin transforms of rational functions and investigate their analytic continuations. LÄS MER

  4. 4. Managing the Urban Greens : Maintaining ecological functions in human dominated landscapes

    Författare :Erik Andersson; Thomas Elmqvist; Jon Sadler; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Natural Resources Management; naturresurshushållning;

    Sammanfattning : At the core of this thesis lie two realisations: First, like other ecosystems, those in urban landscapes provide humans with a number of ecosystem services, some recognized while others are not. Second, in cities just as in other intensively used social-ecological systems, management is of central importance. LÄS MER

  5. 5. Embedded Languages for Describing and Verifying Hardware

    Författare :Koen Lindström Claessen; Chalmers University of Technology; []
    Nyckelord :specification languages; formal verification; synchronous hardware description; functional programming; embedded languages;

    Sammanfattning : Lava is a system for designing, specifying, verifying and implementing hardware. It is embedded in the functional programming language Haskell, which means that hardware descriptions are first-class objects in Haskell. LÄS MER
