  1. 1. The importance of waves in space plasmas : Examples from the auroral region and the magnetopause

    Författare :Gabriella Stenberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; Plasma waves; magnetospheric physics; magnetopause; auroral region; wave distribution function; space exploration; reconnection; current tubes; Rymd- och plasmafysik; Space physics; Rymdfysik; rymdfysik; Space Physics;

    Sammanfattning : This thesis discusses the reasons for space exploration and space science. Space plasma physics is identified as an essential building block to understand the space environment and it is argued that observation and analysis of space plasma waves is an important approach.Space plasma waves are the main actors in many important processes.

    Sammanfattning : This practical artistic research project (Documented Artistic Research Project (Doctoral Thesis)) explores how the performance of acoustic sound in dialogue with site can create a sonic scenography, experienced by an audience from within the sonic structures. Six art projects were carried out in the context of this research.

  4. 3. Cluster Observations and Theoretical Explanations of Broadband Waves in the Auroral Region

    Författare :Marie Backrud; Jan-Erik Wahlund; Mats André; David Knudsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; ion acoustic waves; auroral region; anomalous resistivity; Cluster; Rymd- och plasmafysik; Space physics; Rymdfysik;

    Sammanfattning : Broadband extremely low-frequency wave emissions below the ion plasma frequency have been observed by a number of spacecraft and rockets on auroral field lines. The importance of these broadband emissions for transverse ion heating and electron acceleration in the auroral regions is now reasonably well established. LÄS MER

  5. 4. Single layer near-field acoustic imaging in space-invariant reflective environments

    Författare :Elias Zea; Ines Lopez Arteaga; Efren Fernandez-Grande; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; near-field acoustic holography; field separation techniques; single layer; space-invariance; reflective envirionments; närfält akustisk holografi; fältseparationstekniker; enkelt lager; utrymmes invarians; reflekterande miljöer; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The visualization of optical fields, or widely known as photography, is a common practice that can also be applied to acoustic fields. No less than three decades of research in acoustic imaging demonstrate its potential and relevance in plenty applications such as sound source identification and localization, as well as characterization of noise generation mechanisms.

  7. 5. Noise design : Architectural Modelling and the Aesthetics of Urban Acoustic Spase

    Författare :Björn Hellström; KTH; []
    Nyckelord :architecture; music; aesthetics; sound art; acoustic space; sound design; sound effect; sound identity; sound morphology; graphic notation; sampling culture; acousmatics; metabolic effect; schizophonia;

    Sammanfattning : Noise Design takes up a structural approach to sound issuesin general and more particularly to urban acoustic space. Whilemost recent research efforts in the field adopt a defensiveattitude by seeking to protect people from sounds, this bookcelebrates our constructive and creative relations with thesound world and develops methods to manage sounds as mediatorsof qualitative information.
