1. 1. Uncommon Ground : Urban Form and Social Territory

   Författare :Eva Minoura; Daniel Koch; Meta Berghauser Pont; Alexander Ståhle; Stephen Marshall; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; territoriality; interface; social sustainability; morphology; commons; stewardship; open space; yards; spatial analysis; Architecture; Arkitektur;

   Sammanfattning : Implicit in any urban design is a negotiation between public and private interests. Such a negotiation is articulated and made legible in the facades, fences and even more subtle edges separating this from that. A complex variety of spatial situations are produced depending on how spaces are framed, how interfaces are materialized. LÄS MER

3. 2. Direct Ground Cooling Systems for Office Buildings

   Författare :Taha Arghand; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ground heat exchangers; Energy renovation; Renewable energy; GeoTABS; Active chilled beams; Geocooling systems; TABS; ground-coupled cooling; Passive ground cooling; Thermal comfort; Direct ground cooling; Energy efficiency; Boreholes; Ceiling cooling panels; High-temperature cooling; Optimization; Comfort cooling;

   Sammanfattning : The solving of crucial global energy challenges hinges on improving energy efficiency in building energy systems. Accomplishing energy-efficiency targets often entails incorporating sustainable energy sources into the energy supply system. LÄS MER

4. 3. Capacity-controlled Ground Source Heat Pump Systems for Swedish single-family dwellings

   Författare :Hatef Madani; Per Lundqvist; Joachim Claesson; Jose Miguel Corberan Salvador; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Pump; Capacity control; ground; ground source; geothermal;

   Sammanfattning : The overall objective of this thesis is to develop a structured method to approach the challenge of better understanding the techniques and potential for capacity control in Ground Source Heat Pump (GSHP) systems used in Swedish single-family dwellings. This thesis aims at development of a generic model of the system that can be used for comparative, descriptive, and predictive analysis of capacity controlled GSHP systems in single-family dwellings.

5. 4. An experimental investigation of spur gear efficiency and temperature : A comparison between ground and superfinished surfaces

   Författare :Martin Andersson; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; ground; superfinished; efficiency; temperature; running-in; dip lubrication; spray lubrication; Machine Design; Maskinkonstruktion;

   Sammanfattning : This thesis focuses on reliability when testing gear efficiency and on how gear mesh efficiency can be increased without detrimental effects on the gears. Test equipment commonly used in gear research was analysed to identify important parameters for gear efficiency testing. LÄS MER

7. 5. Social below ground : Life-history and gut microbiome of Damaraland mole-rats

   Författare :Hanna Bensch; Markus Zöttl; Jonas Waldenström; Daniel Lundin; Sarah Knowles; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary Biology; Evolutionsbiologi; Ecology; Ekologi;

   Sammanfattning : Studying the consequences of variation in individual life-histories is vital for our understanding of the evolution of animal societies. In this thesis, I study the ecology and consequences of group living on growth, survival, reproduction, and the gut microbiome of the Damaraland mole-rat (Fukomys damarensis), a subterranean cooperatively breeding mammal.
