1. 11. Power System Oscillations - Detection, Estimation and Control

   Författare :Morten Hemmingsson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER

3. 12. On a learning system for industrial automation : Model-based control and diagnostics for decision support

   Författare :Moksadur Rahman; Konstantinos Kyprianidis; Anders Avelin; Gunnar Bengtsson; John Hedengren; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning system; Supervisory system; Pulp and paper; Micro gas turbine; Process modelling; Model-based control; Diagnostics; Decision support; Anomaly detection; Fault detection; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Access to energy is fundamental to economic and technological advancement. Hence, the more the world develops, the greater the demand for energy becomes. Evidently, the production and consumption of energy alone account for more than 80% of global anthropogenic greenhouse gas (GHG) emissions. LÄS MER

4. 13. The Global Art World, Inc. : On the globalization of contemporary art

   Författare :Charlotte Bydler; Hedvig Brander Jonsson; Hans Hayden; Sarat Maharaj; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Art history; globalization; art world-system; biennials; contemporary art; art historiography; Arthur C. Danto; Gayatri Chakravorty Spivak; Gerardo Mosquera; Paul Virilio; interpellation; Konstvetenskap; Art; Konstvetenskap;

   Sammanfattning : This study examines certain segments of the art world-system in which geographical distances seemed to vanishing as a result of faster and more intense interaction levels. This particular art world-system has been conceptualized in contradictory ways. LÄS MER

5. 14. Orienting West Mexico: The Mesoamerican World System 200-1200 CE

   Författare :Peter F. Jimenez Betts; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Mesoamerica; Archaeology; World-Systems theory; World-Systems analysis; Nested Networks; West Mexico; Central Mexico; Early Classic; Epiclassic; Early Postclassic;

   Sammanfattning : As world-systems theory came to the fore in archaeology during the 1980s and 1990s, it became evident that the analysis of pre-capitalist core/periphery relations required modifications of this theory for its further use in the discipline. As a result, the comparative approach for world-systems analysis (Chase-Dunn and Hall 1997) discerned four interaction networks that defined pre-capitalist world-systems. LÄS MER

7. 15. The Urk World : Hibernating Infrastructures and the Quest for Urban Mining

   Författare :Björn Wallsten; Joakim Krook; Stefan Anderberg; Vasilis Galis; Simon Marvin; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban mining; infrastructure; material flow analysis; hibernating stocks; copper;

   Sammanfattning : This PhD thesis concerns urban mining, an umbrella term for different recycling strategies aimed to recover materials from the built environment. More specifically, it focuses on hibernating urban infrastructures, that is: cables and pipes that have been left behind in their subsurface location after they were disconnected. LÄS MER
