  2. 11. Thin Film Plate Acoustic Resonators for Frequency Control and Sensing Applications

    Author : Lilia Arapan; Ventsislav Yantchev; Ilja Katardjiev; Enrique Iborra; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electro-Acoustics; FPAR; Lamb waves; aluminium nitride; interdigital transducer; phase noise; temperature compensation; power handling; sensitivity; zero group velocity; intermode coupling; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : The recent development of the commercially viable thin film electro-acoustic technology has triggered a growing interest in the research of plate guided wave or Lamb wave components owing to their unique characteristics. In the present thesis i) an experimental study of the thin film plate resonators (FPAR) performance operating on the lowest symmetrical Lamb wave (S0) propagating in highly textured AlN membranes versus a variety of design parameters has been performed.

  4. 12. On properties of generalizations of noise sensitivity

    Author : Malin Palö Forsström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In 1999, Benjamini et. al. published a paper in which they introduced twodefinitions, noise sensitivity and noise stability, as measures of how sensitiveBoolean functions are to noise in their parameters. READ MORE

  5. 13. Receptivity, Stability and Sensitivity analysis of two- and three-dimensional flows

    Author : Guillaume Chauvat; Ardeshir Hanifi; Dan S. Henningson; Ulrich Rist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary-layers; stability; receptivity; sensitivity; transition; mode decomposition; Engineering Mechanics; Teknisk mekanik;

    Abstract : This work deals with various aspects of boundary-layer stability. Modal and non-modal approaches are first used in the study of the global stability of a jet in crossflow. READ MORE

  6. 14. Studies of acoustic waves, noise and charge pumping using single-electron devices

    Author : Martin Gustafsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; single-electron pump; single-electron transistor; surface acoustic wave; single-electron devices; charge pumping; TLF; SINIS turnstile; electrometer; two-level fluctuator; single-photon detector; noise; SAW; SET;

    Abstract : This thesis covers a range of experiments on single-electron devices, electrical circuits that utilize the discreetness of the electron charge. The Single-Electron Transistor (SET) is of special importance among these, being the most sensitive electrometer demonstrated, and sufficiently mature to serve as a building block in sensors and detectors for physical phenomena that can be transformed into charge signals.

  7. 15. Cold-Electron Bolometer with Superconductor-Insulator-Normal Metal Tunnel Junctions

    Author : Ian Jasper Agulo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; temperature sensitivity; cryogenfree; power sensitivity; noise equivalent power; cold-electron bolometer; SIN tunnel junctions; electron cooling;

    Abstract : The Cold-Electron Bolometer (CEB) is an ultrasensitive device designed for the detection of radiation in the terahertz region of the electromagnetic spectrum. The key to its sensitivity is the electron cooling of the absorber by the superconductor-insulator-normal metal (SIN) tunnel junction. READ MORE
