  1. 1. Ionization of large molecules with short laser pulses

    Författare :Mikael Kjellberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Photoelectron spectroscopy; Momentum mapping imaging; thermal ionization; above threshold ionization; molecular fusion; fullerenes; polyaromatic hydrocarbons; femtosecond-laser.;

    Sammanfattning : The decay dynamics of fullerenes and polyaromatic hydrocarbons (PAH) after femtosecond-laser excitation have been studied experimentally by electron momentum mapping and mass spectrometry. The electron spectra of fullerenes and large PAH-molecules were found to be exponentially decreasing with energy without any distinct peaks outside the photon energy. LÄS MER

  3. 2. Model driven process planning for machining : Theory, application and improved information standards for efficient product realization

    Författare :Mikael Hedlind; Torsten Kjellberg; Fumihiko Kimura; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; modeling; ISO 10303; CADCAM; kinematics; Beredning; modellering; ISO 10303; CADCAM; kinematik; SRA - Production; SRA - Produktion;

    Sammanfattning : Model driven process planning is a methodology that emphasizes the application of models to create, represent and use information of products, processes and resources. Industry today stores information in a fragmented manner, mainly document centered with the consequence of data duplication requiring comprehensive data management and maintenance. LÄS MER

  4. 3. Architecting model driven system integration in production engineering

    Författare :Yujiang Li; Lars Mattsson; Gunilla Franzén Sivard; Torsten J. A. Kjellberg; Mikael Hedlind; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System architecture; system integration; information model; ISO 10303; application context; implementation context; implementation model.; Production Engineering; Industriell produktion;

    Sammanfattning : System integration is a key enabler to maximize information value in an engineering context. The valuable information is normally represented by information models which play a decisive role in the implementation of system integration. LÄS MER
