1. Tycho-Gaia and beyond: Combining data for precision astrometry
Sammanfattning : Astrometry aims at producing a three-dimensional map of positions and motions of stars and other celestial bodies in a consistent coordinate system covering the whole sky. This is best done from space, which provides a way of scanning the entire sky by a single instrument in a thermally stable environment. LÄS MER
2. Digital product catalogues : an evaluation of presentation and visualization techniques
Sammanfattning : This licentiate thesis concerns advanced digital product catalogues, with the main focus on product presentation. A computer based digital product catalogue opens new possibilities for advanced product presentation and integration into the existing compute environment. Several new possibilities for product presentation become available. LÄS MER
3. Gravure vs. Web-offset! : a changing world in publication printing 1986-2006
Sammanfattning : The European publication printing industry and its markets have undergone profound structural changes between 1986 and 2006. This thesis is an investigation of these changes and of how the publication industry has been affected, as well as of the balance between publication gravure and commercial heat-set web-offset.

4. Galactic Structure Revealed by Space Astrometry
Sammanfattning : 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.

5. Suspended Value : Using Coins as Pendants in Viking-Age Scandinavia (c. AD 800–1140)
Sammanfattning : The use of coins as pendants is a common practice in the Scandinavian Viking Age (c. AD 800–1140). About three per cent of the coins circulating in Scandinavia show signs of having been adapted for suspension, either with a small hole or a loop. Modifying coins in this way changes the nature of the object. LÄS MER
