  1. 1. Microwave-Assisted Air-Dehydration of Fruits and Vegetables Processing Conditions and Product Quality

    Author : Tomas Funebo; Chalmers University of Technology; []
    Keywords : dielectric properties; pre-treatment; dehydration; permittivity; microwave; fruits; vegetables; multimode;

    Abstract : This thesis is focused on aspects of microwave-assisted hot-air drying of fruits and vegetables. The two material coefficients, the relative permittivity (ε) and the loss factor (ε), determine the interaction of microwave energy with foods. READ MORE

  2. 2. Degenerate and nondegenerate Josephson parametric oscillators for quantum information applications

    Author : Andreas Bengtsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum information; superconducting circuits; multimode; circuit quantum electrodynamics; SQUID; Parametric oscillations;

    Abstract : Parametric oscillations are well studied phenomena, with applications in amplification, quantum optics, and quantum information processing. They can occur as a parameter of a system, such as the resonant frequency, is being modulated or “pumped” by an external field. READ MORE

  3. 3. Multimode resonant X-ray scattering of free molecules

    Author : Nina Ignatova; Victor Kimberg; Faris Gel’mukhanov; Sergey Polyutov; Hans Ågren; Piero Decleva; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; X-ray absorption spectroscopy; core-excited state; nuclear dynamic; wave-packet; resonant inelastic X-ray scattering; Franck-Condon; water; methanol; water isotopomer; pump-probe; quantum chemistry; ultrafast dissociation; Kemi; Chemistry; Physics; Fysik;

    Abstract : This thesis is focused on the role that nuclear dynamics plays in the formation of X-ray absorption (XAS) and resonant inelastic X-ray scattering (RIXS) spectra of multimode free molecules. A combined approach based on ab initio electronic structure methods and quantum nuclear wave packet dynamics is applied to two systems -- water and methanol in the gas phase. READ MORE

  4. 4. Design, Simulation and Characterization of Some Planar Lightwave Circuits

    Author : Yaocheng Shi; Anand Srinivasan; Sailing He; Daniel Erni; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; planar lightwave circuit; waveguide; coupler; multimode interference; photonic crystal waveguide; de multiplexer; triplexer; polarization beam splitter; dry etching; carrier life time.; Photonics; Fotonik;

    Abstract : Optical devices based on planar lightwave circuit (PLC) technology have the advantages of small size, high reliability, possibility for large scale production, and potential integration with electronics. These devices are widely employed in optical telecommunications, sensing, data storage, imaging, and signal processing. READ MORE

  5. 5. Parametric interactions with signals and the vacuum

    Author : Michael Roger Andre Simoen; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vacuum; circuit-QED; interferometer; SQUID; dynamical Casimir effect; multimode resonator; pumpistor; mode conversion; superconducting circuits; parametric amplification;

    Abstract : In this thesis I present different experiments on superconducting circuits exploring parametric interactions with external signals and the vacuum in the microwave regime. These parametric processes are the result of the periodic modulation of a property of a system which results in different interactions. READ MORE
