  2. 1. Condition monitoring of machine tools and machining processes using internal sensor signals

    Author : Jari Repo; Mihai Nicolescu; Dragos Axiente; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring; machine tool; machining process; milling; position encoders; signal analysis; Mechanical engineering; Maskinteknik; Materials science; Manufacturing and materials engineering;

    Abstract : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and achieving a more robust machining process. Failures in the machining process and machine tool components may also have negative effects on the final produced part. READ MORE

  4. 2. Camera Modelling and Calibration with Machine Vision Applications

    Author : Anders Ryberg; Bengt Lennartson; Anna-Karin Christiansson; Anders Heyden; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Camera model; Camera calibration; Fisheye camera; Catadioptric camera; Stereo vision; Other technology; Övriga teknikvetenskaper; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. READ MORE

  5. 3. Novel beam shaping and computer vision methods for laser beam welding

    Author : Yongcui Mi; Antonio Ancona; Fredrik Sikström; Isabelle Choquet; Högskolan Väst; []
    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

  6. 4. Condition Monitoring in Machining Using Internal Sensor Signals

    Author : Jari Repo; Cornel Mihai Nicolescu; Terje Lien; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Condition monitoring; machine tool; machining process; milling; position encoders; tool wear detection; signal analysis; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and to achieve a more robust machining process. Any failure in the machining process and machine tool components may have negative effects on the final produced part. READ MORE

  7. 5. Knowing in practice : a tool in the production of intensive care

    Author : Ann-Charlott Wikström; Högskolan Väst; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; accounting practices; competence; ethnography; human-human-machine; interaction; intensive care; meaning; morality; technology; Caring sciences; Vårdvetenskap; Vårdvetenskap; Nursing science; accounting practices; competence; ethnography; human-human-machine; interaction; intensive care; meaning; morality; technology;

    Abstract : The overall aim with the the present thesisi was to find out how intensive care is produced by focusing on the ICU staffs interaction with each other and the technological tools they use. Theoretical perspective draws on socio cultural theory and the concepts accounting practices, moralöity in discourse and workplace research. READ MORE
