    Sammanfattning : There is a consensus worldwide that the share of renewable energy sources should be increased to mitigate climate change. The strive to increase the renewable energy fraction can partly be met by an increased utilization of different biomass feedstocks. LÄS MER

  3. 3. Reuse of Engineering Knowledge: Perspectives on Experience-Based Codified Knowledge in Incremental Product Development

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Daniel Stenholm; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; engineering knowledge; knowledge management life cycle; engineering checksheet; knowledge assets; experience-based knowledge; knowledge reuse; knowledge management;

    Sammanfattning : Product development is a knowledge-intensive activity and as products become more complex and competition intensifies, the amount of knowledge increases. A prerequisite for engineers who apply current best practices and continuously improve their working methodologies is to efficiently reuse existing knowledge. LÄS MER

  4. 4. Detection of Partial Discharges at Fast Rising Voltages

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Thomas Hammarström; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partial discharges; cavities; repetitive voltages; high dV dt.; square like voltages; short rise time; measurements;

    Sammanfattning : The present demand for higher efficiency and flexibility in the energy sector has ledto an increased use of power electronic generated waveforms as these allow energyconversion between different frequencies including DC. The generated waveformsare usually synthesized by so called Pulse Width Modulation (PWM) techniques,where the desired waveform is approximated by a number of square shaped pulseswith a short rise time.

  5. 5. Perceived Quality of Cars. A Novel Framework and Evaluation Methodology

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Kostas Stylidis; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; luxury; knowledge management; engineering; premium; design; engineering; automotive; product quality; product development; aesthetics; perceived quality;

    Sammanfattning : The supremacy of the automotive manufacturers today is no longer driven by them achieving a superior manufacturing quality but increasingly depends on the customer’s quality perception. Average car consumers see a car’s quality as a fancy mixture of design, aesthetics, their own previous experiences and performance characteristics of the vehicle, unlike a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved in the modern car creation.
