  2. 1. Descriptive Set Theory and Applications

    Author : Joao Pedro Paulos; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sets of Uniqueness; Operator U-sets; Thin Sets; Descriptive Set Theory; ; Operator U0-sets; Point Spectrum; Reflexivity; Fourier Algebra; Jamison sequences; Harmonic Analysis;

    Abstract : The systematic study of Polish spaces within the scope of Descriptive Set Theory furnishes the working mathematician with powerful techniques and illuminating insights. In this thesis, we start with a concise recapitulation of some classical aspects of Descriptive Set Theory which is followed by a succint review of topological groups, measures and some of their associated algebras.

  4. 2. Never Heard Before: A Musical Exploration of Organ Voicing

    Author : João Segurado; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Optimisation and Application of Intense High-Order Harmonic Pulses

    Author : Lena Roos; Atomfysik; []
    Keywords : 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;

    Abstract : 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. READ MORE
