1. 11. Designing Information Systems : A pragmatic account

   Författare :Jonas Sjöström; Pär Johan Ågerfalk; Göran Goldkuhl; Else Nygren; Richard Baskerville; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information systems; design; pragmatism; design research; it artefact; Informatics and systems science; Informatik och systemvetenskap; Computer and systems science; Data- och systemvetenskap; Informatics; Informatik; Data- och systemvetenskap; Computer Systems Sciences;

   Sammanfattning : Information technology (IT) plays an increasingly important role for individuals, organizations, markets, and society as a whole. IT systems are artefacts (human made objects) designed for various purposes. LÄS MER

3. 12. Large-Scale Production and Use of Biomethane

   Författare :Alberto Alamia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dual fuel; Biomass gasification; SNG; power-to-gas; well-to-wheel; biomethane; biorefinery; GoBiGas; DFB gasifier; process simulation;

   Sammanfattning : Societal ambitions to create an economy based on renewable resources, require the development of technologies transforming these resources into energy-carrying products and biomaterials. Dual fluidized bed (DFB) gasification represents a key technology for achieving sustainability targets, as it is a scalable and highly efficient route for the conversion of biomass. LÄS MER

4. 13. Large-scale simulation of neuronal systems

   Författare :Mikael Djurfeldt; Örjan Ekeberg; Charles Peck; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : Biologically detailed computational models of large-scale neuronal networks have now become feasible due to the development of increasingly powerful massively parallel supercomputers. We report here about the methodology involved in simulation of very large neuronal networks. LÄS MER

5. 14. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

   Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

   Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER

7. 15. On performance limitations of large-scale networks with distributed feedback control

   Författare :Emma Tegling; Henrik Sandberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. LÄS MER
