  1. 1. Never Heard Before: A Musical Exploration of Organ Voicing

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :João Segurado; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :HUMANIORA; HUMANITIES; voicing; voicing; sound; listening; pipe; organ; tone; musical composition; musical performance; experimental; collaboration; artistic research; ethnography; musique concrète; transient; attack; steady-state; harmonic spectrum; languid; toe-hole; mouth; flue; reed; Studio Acusticum; Gerald Woehl; Piteå;

    Sammanfattning : This study describes the role of organ sounds in musical performance and exa- mines the visions and artistic perspectives of the voicer, who creates the sounds, and the organist, who uses them in performance. Organ pipe sounds are shaped in a process of gradual transformation called voicing, to suit the practice of musical performance, and they influence that practice in significant ways. LÄS MER

  2. 2. Optimisation and Application of Intense High-Order Harmonic Pulses

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Lena Roos; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherent radiation; Optimisation; Multiphoton ionisation; Phase matching; Physics; Fysik; Atomic and molecular physics; Atom- och molekylärfysik; Laserteknik; Laser technology; High-power lasers; Short pulses; High-order harmonic generation; Short wavelength; Fysicumarkivet A:2001:Roos;

    Sammanfattning : The high-order harmonics that are created in the interaction between an intense laser pulse (around 1014 W/cm2) and a gas medium are studied. The high-order harmonic radiation is a relatively new source of coherent radiation in the short wavelength range. LÄS MER

  5. 5. Calculated Potential Energy Surfaces and Vibrational Analysis

    Detta är en avhandling från Department of Theoretical Chemistry, Lund University

    Författare :Niclas Forsberg; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Benzene; HCO; NEMO; Imaginary Level Shift; Double Harmonic Approximation; Potential Energy Surface; CASPT2; Franck-Condon Factors; CASSCF; p-Benzosemiquinone; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Sammanfattning : The focus of this thesis is on the calculation of potential energy surfaces and on the study of vibrational properties. For example: - We have developed a new method for calculation of Franck-Condon factors. - We have calculated full energy surfaces of the ground (X2A’) the excited (B2A’) states of the formyl radical.
