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

    Författare :Jesper Bank; [2006]
    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

  2. 2. Function Variables for Constraint Programming

    Detta är en avhandling från Uppsala : Institutionen för informationsvetenskap

    Författare :Brahim Hnich; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Constraint saisfaction; constraint programming; high-level modelling; abstraction; reformulation; function variables.; Datalogi; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; Computer Science; data- och systemvetenskap;

    Sammanfattning : Quite often modelers with constraint programming (CP) use the same modelling patterns for different problems, possibly from different domains. This results in recurring idioms in constraint programs. Our approach can be seen as a three-step approach. First, we identify some of these recurring patterns in constraint programs. LÄS MER

  3. 3. The function concept and university mathematics teaching

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Olov Viirman; Karlstads universitet.; Högskolan i Gävle.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics; mathematics; university education; commognitive framework; function concept; discourse; teaching;

    Sammanfattning : This thesis concerns the teaching of mathematics at university level, with a particular focus on the teaching of the function concept. The main aim of the thesis is describing and analysing the teaching practices of university mathematics teachers regarding the function concept, and how this concept is constituted through these practices.

    Sammanfattning : There is a large need for accurate methods detecting cardiovascular diseases, since they are one of the leading causes of mortality in the world, accounting for 29.3% of all deaths. LÄS MER

  5. 5. Hand function, Everyday Occupations and Wellbeing in Individuals with Systemic Sclerosis

    Detta är en avhandling från Department of Clinical Neuroscience, Lund University

    Författare :Gunnel Sandqvist; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arbetsmiljömedicin; Yrkesmedicin; industrial medicine; Occupational health; occupational therapy interventions; wellbeing; everyday occupations; Systemic sclerosis; hand function;

    Sammanfattning : Systemic sclerosis (scleroderma) is a connective tissue disease which, in various ways, influences an individual’s ability to participate in everyday occupations. The general objective of this work was to elucidate the consequences of scleroderma with respect to hand function, everyday occupations and wellbeing, in order to provide a knowledge base suitable for occupational therapy interventions.
