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

    Författare :Daniel Stenholm; Chalmers tekniska högskola; []
    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

    Författare :Jonathan Fagerström; Christoffer Boman; Dan Boström; Marcus Öhman; Bengt-Johan Skrifvars; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; biomass; thermochemical fuel conversion; combustion; fine particle emissions; slag formation; fixed-bed; ash chemistry; fuel engineering; release;

    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

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

    Författare :Thomas Hammarström; Chalmers tekniska högskola; []
    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.

  7. 5. Knowledge engineering in the virtual enterprise : exploring a maturity-based decision support

    Författare :Christian Johansson; Tobias Larsson; Andreas Larsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge Engineering; Knowledge Maturity; Functional Product Development; Decision Making; Funktionella produkter;

    Sammanfattning : In product development, lead-time reduction, cost reduction, and quality improvement are issues that companies want to improve on to increase competitiveness. One recent approach to reach this - particularly in the aerospace industry where the complexity of product offers is steadily increasing - is to manage risk by forming virtual enterprises. LÄS MER
