  1. 11. Quality Management for sustainable product development: Adaptations of practices and tools

    Författare :Vanajah Siva Subramaniam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable product development; environment; Robust Design Methodology.; adaptation; Quality Management; integration; sustainability;

    Sammanfattning : Quality Management is a management approach that has been suggested to project a number of synergies with sustainable development in general, and environmental sustainability in particular. For example, the principles of customer focus and continuous improvement are applicable in practices supporting environmental sustainability, especially in product development. LÄS MER

  3. 12. The Nitrogen Cycle in Soil - Climate Impact and Methodological Challenges in Natural Ecosystems

    Författare :Anna-Karin Björsne; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nitrogen cycle; 15N tracing experiments; gross N transformation rates; climate change; climate treatments; mineralization; nitrification; forest fertilization; nitrous oxide emissions; boreal forest soil; tree species; soil organic matter; C:N ratio;

    Sammanfattning : Nitrogen (N) is a fundamental element for life, and limiting in many terrestrial ecosystems. In non-N-fertilized ecosystems, the N inputs can be low, and the nutrient availability for plants is determined by the internal cycling of N. LÄS MER

  4. 13. Ring-opening catalysts for cetane improvement of diesel fuels

    Författare :Ulf Nylén; Magali Boutonnet; Sven Järås; François Garin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ring opening selective ; naphthenic structure; indan; light cycle oil LCO ; cetane; Pt-Ir catalyst; microemulsion; XPS; TPR; TEM; DRIFTS; sulphur analysis; GC-SCD; Chemical engineering; Kemiteknik;

    Sammanfattning : The global oil refining industry with its present product distribution essentially shifted towards fuels such as gasoline and diesel will most likely hold the fort for considerable time. However, conditions are changing and refinery survival will very much depend on long-term planning, process and product flexibility and being at the frontiers of refining technology, a technology where catalysts play leading roles.

  5. 14. Condition-Based Maintenance: Selection and Improvement of a Cost-Effective Vibration-Based Maintenance Policy for Rolling element Bearings

    Författare :Basim Al-Najjar; Sherwin David; Bo Bergman; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; a cost-effective vibration-based maintenance policy.; Integrated maintenance; Condition monitoring and control; Total Time on Test-plots; Vibration monitoring; effectiveness and accuracy; Failure causes and mechanisms; Maintenance quality; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Commercial and industrial economics; Industriell ekonomi; Maintenance Technology; Terotechnology;

    Sammanfattning : Modern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. LÄS MER

  7. 15. Collision-free path coordination and cycle time optimization of industrial robot cells

    Författare :Domenico Spensieri; Stiftelsen Fraunhofer-Chalmers Centrum för Industrimatematik (FCC); []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cycle time optimization; multi-robot collision avoidance; production planning; multi-robot routing and coordination;

    Sammanfattning : In industry, short ramp-up times, product quality, product customization and high production rates are among the main drivers of technological progress. This is especially true for automotive manufacturers whose market is very competitive, constantly pushing for new solutions. LÄS MER
