  1. 1. Flotation of silicate minerals physico-chemical studies in the presence of alkylamines and mixed (cationic/anionic/non-ionic) collectors

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Vidyadhar Ari; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral Processing; Mineralteknik;

    Abstract : The mechanism of adsorption of long chain alkyl primary amines and, co-adsorption of amines and alcohols on silicate minerals (quartz and feldspar) were studied using FTIR (DRIFT and IRRAS) and XPS spectroscopy methods. The spectroscopy data were correlated with zeta-potential and Hallimond flotation results. READ MORE

  2. 2. Dead-Time Compensation and Performance Monitoring in Process Control

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Ari Ingimundarson; Lunds universitet.; Lund University.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Abstract : Popular Abstract in Swedish Avhandlingen består av två delar. Den första delen behandlar reglering av processer med lång dödtid. Avhandlingen ger förslag på hur regulatorer för dessa processer ska dimensioneras och jämför sedan prestanda hos dessa regulatorer med vanliga PID-regulatorer. READ MORE

  4. 4. Managing Interruptions in Manufacturing Towards a Theoretical Framework for Interruptions in Manufacturing Assembly

    University dissertation from Skövde : Högskolan i Skövde

    Author : Ari Kolbeinsson; Högskolan i Skövde.; Högskolan i Skövde.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interruptions; Manufacturing; Mobile Devices; Cognition; Technology; Teknik; User Centred Product Design; Användarcentrerad produktdesign;

    Abstract : The effect of interruptions from ICT systems on assembly workers in manufacturing is examined in this thesis, as is how the risks of errors, increases in assembly time, increased cognitive load and resultant stress can be mitigated, as well as ensuring that important new information is acted upon. To these ends, a literature study was conducted, followed by two studies using an experimental approach in an environment that simulated a manufacturing assembly situation, and used tasks designed to be representative of manufacturing assembly tasks.

  5. 5. Situating interruptions in manufacturing assembly

    University dissertation from Skövde : University of Skövde

    Author : Ari Kolbeinsson; Högskolan i Skövde.; Högskolan i Skövde.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; User Centred Product Design; Användarcentrerad produktdesign;

    Abstract : Interruptions have been studied extensively, with interruptions experiments where tasks performed on computers are interrupted by another task received on the same computer having receiving much of the focus. Additionally, many of the tasks used in existing research have been designed specifically to test the effect of interruptions on humans by making both the interrupting task and the task being interrupted quite difficult.
