1. An Analysis of Spatially-enabled Mobile Decision Support Systems in a Collaborative Decision-Making Environment
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The effectiveness of decision-making processes has been enhanced by integrating multi-criteria decision analysis (MCDA) and geographic information system (GIS) methods to solve more complex spatial problems that were not possible to solve using conventional GIS methods. A spatial decision support system (SDSS) supports various stakeholders in the decision-making process, by processing data using GIS-MCDA methods. READ MORE

3. Ultraluminous sources in X-ray sky surveys
University essay from Uppsala universitet/HögenergifysikAbstract : Ultraluminous X-ray sources (ULXs) are extragalactic, non-nuclear, point-like X-ray sources whose luminosity supersedes that of the Eddington limit of an accreting stellar mass black hole (L> 10 ^ 39 erg / s). Most of them are powered by black holes and neutron stars undergoing genuine super-Eddington accretion, with a small handful of candidates being consistent with sub-Eddington accretion on an intermediate mass black hole.

4. Stellar populations in the Green Pea galaxy J1457+2232 : Study of possible age gradients by using highly resolved HST broad band imaging of the Green Peagalaxy SDSS-J145735.13+223201.8 at redshift 0.15.
University essay from Stockholms universitet/Institutionen för astronomiAbstract : Abstract In this report I present a study of possible age gradients in the Green Pea galaxy J145735.13+223201.8 to be able to conclude if there is an extended star forming history in such a galaxy. READ MORE

5. Examining variable galactic nuclei with the help of astronomical databases and archives
University essay from Uppsala universitet/Teoretisk astrofysikAbstract : There exists many astronomical objects that vary in brightness. Objects such as variable stars like the Cepheids that periodically expands and contracts their outer layers, or the active galactic nuclei (AGN) where accretion of matter into a black hole generates a often varying brightness.
