  1. 1. Space Plasma Dynamics : Instabilities, Coherent Vortices and Covariant Parametrization

    Författare :David Sundkvist; Jan-Erik Wahlund; Andris Vaivads; Stuart Bale; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; space physics; plasma; instabilities; turbulence; coherent structures; vortex; self-organization; magnetosphere; waves; electromagnetism; covariant; space instrumentation; Rymd- och plasmafysik; Space physics; Rymdfysik;

    Sammanfattning : The magnetospheric cusps are two funnel-like regions of Earth's magnetosphere where solar wind plasma can have direct access to the ionosphere. The cusps are very dynamic regions where wave-particle interactions continuously take place and redistribute energy among different particle populations. LÄS MER

  2. 2. Space Craft : Globalization and Governmentality in Regional Development

    Författare :Andreas Öjehag-Pettersson; Mikael Granberg; Hans Lödén; Malin Rönnblom; Wendy Larner; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Assemblage; Space; Territory; Multimodal Discourse Analysis; Innovation; Competitiveness; Statsvetenskap; Political Science;

    Sammanfattning : This thesis explores two related purposes. First, it theoretically investigates how the broad literature on globalization is nested in debates concerning the nature of concepts such as space and territory. LÄS MER

  3. 3. After Space Utopia : Post-Soviet Russia and Futures in Space

    Författare :Roman Privalov; Johan Eriksson; Mats Braun; Arita Holmberg; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; space; Russia; utopia; postcolonialism; assemblage; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Since the early 2000s, new projects of space expansionism have emerged, including the commercial-, military-driven and scientific projects to colonize the Moon and Mars. The new space expansionism followed a period of comparatively lower attention to space in international politics, and it is sometimes called the New Space Race by analogy to the 20th century Space Race between the USSR and the US.

  4. 4. From meteors to space safety : dynamical models and radar measurements of space objects

    Författare :Daniel Kastinen; Johan Kero; Asta Pellinen-Wannberg; Mats Holmström; Detlef Koschny; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Meteors; meteor shower; atmosphere; meteoroids; meteoroid stream; small-body dynamics; solar system; comets; asteroids; near-Earth objects; space safety; space debris; radar; MU; EISCAT;

    Sammanfattning : Every day the Earth's atmosphere is bombarded by 10-200 metric tons of dust-sized particles and larger pieces of material from space called meteoroids. Dust and meteoroids come from parent bodies such as comets and asteroids, which are remnants from the formation of the solar system. LÄS MER

  5. 5. Waves in space plasmas : Lower hybrid cavities and simple-pole distribution functions

    Författare :Anders Tjulin; Mats André; Hans Pécseli; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; space physics; plasma; waves; dispersion relations; lower hybrid cavities; Cluster; magnetosphere; Rymd- och plasmafysik; Space physics; Rymdfysik;

    Sammanfattning : Waves are a fundamental feature in many parts of physics, since they transport energy without transporting matter. This is the case also in space physics. Waves are responsible for energy transport both between different parts of space and between different particles in the space plasma. LÄS MER
