2. 1. District heating in future Europe : Modelling expansion potentials and mapping heat synergy regions

   Author : Urban Persson; Sven Werner; Lars J. Nilsson; Sweden Gothenburg Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

   Abstract : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.

4. 2. Reading the Sky : From Starspots to Spotting Stars

   Author : Urban Eriksson; Cedric Linder; John Airey; Andreas Redfors; Edward E. Prather; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Astrometry; Astronomy Education Research; Disciplinary Discernment; Extrapolating three-dimensionality; Reading the Sky; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

   Abstract : This thesis encompasses two research fields in astronomy: astrometry and astronomy education and they are discussed in two parts. These parts represent two sides of a coin; astrometry, which is about constructing 3D representations of the Universe, and AER, where for this thesis, the goal is to investigate university students’ and lecturers’ disciplinary discernment vis-à-vis the structure of the Universe and extrapolating three-dimensionality.

5. 3. Stellar Surface Structures and the Astrometric Serach for Exoplnaets

   Author : Urban Eriksson; Lindegren Lennart; Kristianstad University; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astrometry; astronomy;

   Abstract : Measuring stellar parallax, position and proper motion is the task of astrometry. With the development of new and much more accurate equipment, different noise sources are likely to affect the very precise measurements made with future instruments. READ MORE

6. 4. Towards Better Urban Spaces in Harmony with Microclimate: Urban design and planning regulations in hot dry Damascus, Syria

   Author : Moohammed Wasim Yahia; Boende och bostadsutveckling; []
   Keywords : HUMANIORA; HUMANITIES; Architecture; Arid zones; Built environment; Climate; Climatic design; Damascus; Hot dry regions; Landscape elements; Microclimate; Planning regulations; Thermal comfort; Thermal indices; Urban climate; Urban design; Urban planning;

   Abstract : This research is an attempt to develop further understanding of the relationship between microclimate, thermal comfort, urban design and outdoor space users in the hot dry city of Damascus. This is done by studying the impact of urban regulations on microclimate in different urban design patterns in Damascus. READ MORE
