  2. 1. Galactic Structure Revealed by Space Astrometry

    Author : Johan Holmberg; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomi; cosmic chemistry; Galactic structure; Milky Way Galaxy; Galactic kinematics and dynamics; Galactic chemical evolution; moving groups; solar neighbourhood; dark matter; astrometry; Hipparcos; space research; Astronomy; rymdvetenskap; kosmisk kemi; Space technology; Rymdteknik; Fysicumarkivet A:2001:Holmberg;

    Abstract : This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically.

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

    Author : Gabriella Stenberg; Umeå universitet; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Evolving Urban Culture in Transforming Cities Architectural and Urban Design in a Fluid Context

    Author : Mir Azimzadeh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evolution; generative process; space; configuration; culture; society; urban design; architecture; urban spatial systems; metamorphosis; domestic space; public space; place; analytic theory; space syntax; cultural types; local structure; urban function; housing estate; city; spatial interface; street system;

    Abstract : The practice of architectural and urban design being involved in forming the space in our cities and built environments has certain effects on the social life in society that in its turn conditions the performance of the practice. The continuous changes in cities and societies, however, are just partially caused by the practice of architectural and urban design. READ MORE

  6. 4. Space in motion : the art of activating space in-between

    Author : Monica Sand; Abdellah Abarkan; Annette Arlander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; in-between; dispersed production; producer observer; bridge; swing; penelope; Architecture; Arkitektur; Art; Konstvetenskap;

    Abstract : As a contribution to the emerging field of practice-based research in the arts, this thesis aims to activate space, experience and the concept in-between. As the in-between cannot be defined ahead of the rhythmic process it carries out and of which it is a part – a rhythm inherent in the city itself and in knowledge production – it is necessary to produce rhythmic relations between bodies, sites and concepts.

  7. 5. Microsystem Interfaces for Space

    Author : Hugo Nguyen; Greger Thornell; Johan Köhler; Staffan Greek; Uppsala universitet; []
    Keywords : Engineering physics; microelectromechanical system; interface; microfluidics; nanosatellite; space; microsystems; filter; valve; MST; MEMS; Teknisk fysik;

    Abstract : Microsystem interfaces to the macroscopic surroundings and within the microsystems themselves are formidable challenges that this thesis makes an effort to overcome, specifically for enabling a spacecraft based entirely on microsystems. The NanoSpace-1 nanospacecraft is a full-fledged satellite design with mass below 10 kg. READ MORE
