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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Daniel Stenholm; [2018]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Fine particle emissions and slag formation in fixed-bed biomass combustion aspects of fuel engineering

    University dissertation from Umeå : Umeå Universitet

    Author : Jonathan Fagerström; Umeå universitet.; [2015]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Umeå : Umeå Universitet

    Author : Thomas Hammarström; [2011]
    Keywords : 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;

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Christian Johansson; Luleå tekniska universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge Engineering; Knowledge Maturity; Functional Product Development; Decision Making; Funktionella produkter; Functional Product Development;

    Abstract : 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. READ MORE
