  1. 1. Borrowing the Bat's Ear for Automation - Ultrasonic Measurements in an Industrial Environment

    University dissertation from LTH, Lund University

    Author : Gunnar Lindstedt; Lunds universitet.; Lund University.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; electrostatic transducer; piezoelectric transducer; echolocation; bat; automation; localization; recognition; geometry; distance; measurement; ultrasound; robotteknik; reglerteknik;

    Abstract : This work focuses on measurement principles based on ultrasound for applications in industrial automation. The measurements made are of geometric nature. The methods used are when possible based on experience and/or inspiration from the study of bats. READ MORE

  2. 2. Instrumentation and estimation for high temperature control

    University dissertation from Göteborg : Chalmers Reproservice

    Author : Petter Hagqvist; Högskolan Väst.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing and materials engineering; Produktions- och materialteknik; Physics; Fysik; Additive Manufacturing; Automation; Emissivity; Emissivity Compensated Spectral Pyrometry; Laser Metal Wire Deposition; Metal Deposition; Pyrometry; Resistance Feedback Control; Thermometry; Varying Emissivity;

    Abstract : Within a variety of industrially relevant high temperature production processes such as welding, heat treatment and metal deposition, the quality of the manufactured component is largely affected by how well parameters can be controlled during processing. These parameters might be, in the case of metal deposition, power input, material feed, or a parameter which is common for all of the aforementioned processes: material temperature. READ MORE

  3. 3. Representing human-automation challenges

    University dissertation from Chalmers University of Technology

    Author : Jonas Andersson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; human-machine systems; automation; control rooms; cognitive systems engineering;

    Abstract : Automation technology is widely implemented in process control domains due to its benefits of improving efficiency and enhancing control. However, use of automation also introduces an often complex intermediary between the human and the controlled domain, which can obscure from the operator how system functioning is achieved.
