  1. 1. Speciation and Metabolic rate : Insights from an avian hybrid zone

    Författare :S. Eryn McFarlane; Anna Qvarnström; Jenny Boughman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resting metabolic rate; life history; hybridization; speciation; reproductive isolation; Ficedula flycatcher; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. LÄS MER

  3. 2. Theory of economic development : nonlinearity, instability and non-equilibrium

    Författare :Wei-Bin Zhang; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic growth and development; instability; structural change; bifurcation; non-equilibrium; centralization and decentralization; business cycle; the standard neoclassical growth model; growth rate; interest rate; inflation rate; choice of techniques; endogenous technological change;

    Sammanfattning : The objective of this study is to propose an economic development theory within the framework of input-output systems and neoclassical economics. This study consists of nine chapters which are arranged in the following manner:In Chapter I, we discuss development problems, define some essential concepts, and provide a general historical sketch of economic growth theory.

  4. 3. Rate as the relation of changes in two quantities : A variation theory perspective of learning rate of change

    Författare :Per Håkansson; Robert Gunnarsson; Ulla Runesson Kempe; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; rate of change; slope; covariation; functions; mathematics teaching and learning; variation theory; learning study; förändringstakt; lutning; samvariation; funktioner; matematiklärande; variationsteori; learning study;

    Sammanfattning : This thesis comprises three original papers about learning rate of change in school mathematics. The overall aim of the thesis is to contribute with knowledge in this particular area of research. Within this aim, each of the original papers contribute with its own perspective. LÄS MER

  5. 4. Control over Low-Rate Noisy Channels

    Författare :Lei Bao; Mikael Skoglund; Sandro Zampier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor networks; linear quadratic cost; stochastic control; joint source–channel coding; joint coding and control; rate allocation; soft source de- coding; Telecommunication; Telekommunikation;

    Sammanfattning : Networked embedded control systems are present almost everywhere. A recent trendis to introduce radio communication in these systems to increase mobility and flex-ibility. LÄS MER

  7. 5. Condition-based Failure Rate Modelling for Individual Components in the Power System

    Författare :Jan Henning Jürgensen; Patrik Hilber; Lars Nordström; Thomas Welte; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asset management; condition monitoring; diagnostic measures; failure rate; failure rate modeling; transformer diagnostics; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The electrical power grid is one of the most important infrastructures in the modernsociety. It supplies industrial and private customers with electricity and supportsother critical infrastructures such as the water supply. Thus, it is significant that the power grid is a reliable system.
