  1. 1. Hybrid Built-In Self-Test and Test Generation Techniques for Digital Systems

    Författare :Gert Jervan; Zebo Peng; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; system-on-chip; test generation; BIST; hybrid BIST; high-level test; Datavetenskap; Computer science; Datavetenskap;

    Sammanfattning : The technological development is enabling the production of increasingly complex electronic systems. All such systems must be verified and tested to guarantee their correct behavior. As the complexity grows, testing has become one of the most significant factors that contribute to the total development cost. LÄS MER

  3. 2. Type Ia Supernova Cosmology : Quantitative Spectral Analysis

    Författare :Gastón Folatelli; Ariel Goobar; Enrico Cappellaro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supernova; Cosmology; Spectroscopy; Physics; Fysik;

    Sammanfattning : Type Ia supernovae have been successfully used as standardized candles to study the expansion history of the Universe. In the past few years, these studies led to the exciting result of an accelerated expansion caused by the repelling action of some sort of dark energy. LÄS MER

  4. 3. Thermal response test : numerical simulations and analyses

    Författare :Anna-Maria Gustafsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Sammanfattning : When constructing large borehole heat exchanger (BHE) systems, bedrock and borehole thermal properties are vital for a good design. Today's design programs presume conductive heat transfer in both borehole and bedrock. LÄS MER

  5. 4. Thermal response test : method development and evaluation

    Författare :Signhild Gehlin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

  7. 5. Income, Energy Taxation, and the Environment : An Econometric analysis

    Författare :Tarek Ghalwash; Runar Brännlund; Pere Riera; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Household consumption; energy demand; emissions; rebound effect; energy taxation; tax elasticities Environmental services; income elasticities; Engel Curves; income distribution.; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of four papers: two of them deal with the relationship between consumption, energy taxation, and emissions on macro level, and two of them focuses on the effects of changes in consumption and income on the environmental quality on a micro level. The main objective of paper [I] is to examine how exogenous technological progress, in terms of an increase in energy efficiency, affects consumption choice by Swedish households and thereby emissions of carbon dioxide (CO2), sulphur dioxide (SO2) and nitrogen oxide (NOx).
