  1. 1. Vision-based Human Detection from Mobile Machinery in Industrial Environments

    Detta är en avhandling från Örebro : Örebro university

    Författare :Rafael Mosberger; Örebro universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Industrial Safety; Mobile Machinery; Human Detection; Computer Vision; Machine Learning; Infrared Vision; High-visibility Clothing; Reflective Markers; Datavetenskap; Computer Science;

    Sammanfattning : The problem addressed in this thesis is the detection, localisation and tracking of human workers from mobile industrial machinery using a customised vision system developed at Örebro University. Coined the RefleX Vision System, its hardware configuration and computer vision algorithms were specifically designed for real-world industrial scenarios where workers are required to wear protective high-visibility garments with retro-reflective markers.

  2. 2. Machinery diagnostic techniques for maintenance optimization

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Juhamatti Saari; Luleå tekniska universitet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : One of the future challenges of machinery diagnostics and prognosticsis to prepare for the Internet of Things (IoT), where it is possible to change and improve existing approaches drastically. An intensifying application of the IoT will increase the use of embedded sensors and, therefore, create a demand for diagnostic tools where manual workis minimized and is mainly handled by smart algorithms.

  3. 3. The enzymatic machinery of leukotriene biosynthesis Studies on ontogenic expression, interactions and function

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Tobias Strid; Linköpings universitet.; Linköpings universitet.; [2012]

    Sammanfattning : Leukotrienes (LTs) are biologically active arachidonic acid (AA) derivatives generated by the 5-lipoxygenase (5-LO) pathway. They are produced by myeloid cells. 5-LO converts AA to LTA4 in cooperation with 5-LO activating protein (FLAP). LTA4 is converted to LTB4, by LTA4-hydrolase (LTA4H) or to LTC4 by LTC4-synthase (LTC4S). LÄS MER

  4. 4. Lokal förankring och global räckvidd : En studie av teknikutveckling i svensk maskinindustri : [a study of technological development in the Swedish machinery industry]

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Staffan Larsson; Uppsala universitet.; [1998]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Agglomeration theory; technology; innovations; inter-firm relations; local embeddedness; firm performance; machinery industry; Kulturgeografi; SOCIAL SCIENCES Business and economics Human geography; economic geography Human geography; SAMHÄLLSVETENSKAP Ekonomi Kulturgeografi; ekonomisk geografi Kulturgeografi; kulturgeografi; Social and Economic Geography;

    Sammanfattning : Taking its point of departure in the proliferating literature on the localised nature of learning and innovation processes, this thesis sets out to answer the question whether locally embedded firms are more innovative than other firms. The thesis is based on a questionnaire that in the autumn of 1995 was sent to firms producing machinery. LÄS MER

  5. 5. Molecular machinery of a membrane-bound proton pump Studies of charge transfer reactions in cytochrome c oxidase

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Emelie Svahn; Stockholms universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane protein; respiration; redox reaction; cytochrome aa3; cytochrome c oxidase; biokemi; Biochemistry;

    Sammanfattning : In cellular respiration, electron transfer from the breakdown of foodstuff is coupled to the formation of an electrochemical proton gradient. This is accomplished through proton translocation by respiratory complexes, and the proton gradient is subsequently used e.g. to drive ATP production. LÄS MER
