    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser beam welding; Beam shaping; Deformable mirror; Process monitoring; Process control; Model validation; Computer vision; Machine learning; Butt joint; T-joint.; Lasersvetsning; Beam shaping; Deformerbar spegel; Processövervakning; Processkontroll; Modellvalidering; Datorsyn; Maskininlärning; Butt joint; T-fogar;

    Abstract : Laser beam welding has been widely applied in different industrial sectors due to its unique advantages. However, there are still challenges, such as beam positioning in T-joint welding, and gap bridging in butt joint welding,especially in the case of varying gap width along a joint. READ MORE

  2. 2. Advancement of sensor technology for monitoring and control of upstream bioprocesses

    Author : Judit Randek; Carl-Fredrik Mandenius; Gerald Striedner; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In bioprocesses, the upstream process part with cultivation and harvesting steps has decisive influence on the final process outcome, including the quality of the product, the productivity and the yield. To ensure stable product quality of biopharmaceuticals, the U.S. READ MORE

  3. 3. Intensification of the biogas process by improved process monitoring and biomass retention

    Author : Lovisa Björnsson; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOD; hydrogen; on-line; monitoring; biofilm; anaerobic digestion; biogas; Biotechnology; Bioteknik;

    Abstract : The utilisation of energy in the form of biogas is one of the environmentally sound alternatives available using renewable energy sources. Biogas is formed by anaerobic degradation of organic material, the main consistuent being energy-rich methane. READ MORE
