    University dissertation from Göteborg : Chalmers University of Technology

    Author : Petter Hagqvist; Högskolan Väst.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing and materials engineering; Produktions- och materialteknik; Additive Manufacturing; Automation; Emissivity; Emissivity Compensated Spectral Pyrometry; Laser Metal Wire Deposition; Metal Deposition; Pyrometry; Resistance Feedback Control; Thermometry;

    Abstract : For integration of additive manufacturing into industrial production, there is a need for capable yet robust automation solutions. Such solutions are to ensure consistent process outputs, both with regard to deposit geometry and material properties. READ MORE

  4. 2. Cavity Field Control for Linear Particle Accelerators

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

    Author : Olof Troeng; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2019-11-05]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle accelerators; Cavity field control; LLRF; Complex-coefficient systems; Q design; Disturbance-rejecting peak filters;

    Abstract : High-energy linear particle accelerators enable exploration of the microscopic structure of pharmaceuticals, solar cells, fuel cells, high-temperature superconductors, and the universe itself. These accelerators accelerate charged particles using oscillating magnetic fields that are confined in metal cavities. READ MORE

  5. 3. Cavity Field Control for High-Intensity Linear Proton Accelerators

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Olof Troeng; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2017-06-07]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Automatic Control; European Spallation Source;

    Abstract : The European Spallation Source will, once fully operational in 2025, be the world's brightest neutron source. The neutrons will be generated by bombarding a tungsten target with protons accelerated to 96\% the speed of light by electromagnetic fields confined in 155 radio-frequency cavities along the world's most powerful linear accelerator.

    Abstract : Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. READ MORE

  7. 5. Integration of Surface Acoustic Wave and Microfluidic Technologies for Liquid-Phase Sensing Applications

    University dissertation from IEA, LTH, Box 118, SE-221 00 Lund, Sweden

    Author : Kiryl Kustanovich; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IDE; Resonator; SH-SAW; Impedance Spectroscopy; Surface Acoustic Wave; PDMS; LiNbO3; Microfluidics; Sensor;

    Abstract : This thesis discusses a new concept for construction of a novel SAW in-liquid sensor employing surface acoustic wave resonance (SAR) in a one-port configuration. In this concept, the reflective gratings of a one-port SAW resonator are employed as mass loading-sensing elements, while the SAW transducer is protected from the measurement environment, reducing power losses significantly.
