  2. 11. World oil supply and unconventional resources : Bottom-up perspectives on tight oil production

    Author : Henrik Wachtmeister; Mikael Höök; Roger Bentley; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; oil supply; oil production; unconventional resources; tight oil; shale oil; bottom-up model; projections; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : Oil is the world’s largest primary energy source. It dominates the transportation sector which underpins the world economy. Yet, oil is a nonrenewable resource, destined not to last forever. In the mid-2000s global conventional oil production stagnated, leading to rising oil prices and fears of permanent oil scarcity.

  4. 12. Hierarchical Concurrent Systems from a Model-Oriented perspective

    Author : Daniel Einarson; Data Vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; control; systems; numerical analysis; Computer science; Distributed Systems; Hierarchical Systems; Object-Orientation; Model-Orientation; Datalogi; numerisk analys; system; kontroll; Systems engineering; computer technology; Data- och systemvetenskap;

    Abstract : Real world systems are normally considered as hierarchically organized, for example, we see those as hierarchies of systems including subsystems. Examples on this can be seen in organizations where people act in environments and carry within themselves their own internal subsystem of thinking processes. READ MORE

  5. 13. On Modeling and Nonlinear Model Reduction in Automotive Systems

    Author : Oskar Nilsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear systems; model reduction; discrete-time; continuous-time;

    Abstract : The current control design development process in automotive industry and elsewhere involves many expensive experiments and hand-tuning of control parameters. Model based control design is a promising approach to reduce costs and development time. In this process low complexity models are essential and model reduction methods are very useful tools.

  6. 14. Modeling and Model Reduction by Analytic Interpolation and Optimization

    Author : Giovanna Fanizza; Anders Lindquist; György Michaletzky; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytic Interpolation theory with a degree constraint; rational covariance extension problem; spectral estimation; model reduction; optimization; passive system; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : This thesis consists of six papers. The main topic of all these papers is modeling a class of linear time-invariant systems. The system class is parameterized in the context of interpolation theory with a degree constraint. READ MORE

  7. 15. World Wide Workshop: The Craft of Noticing

    Author : Nicolas Cheng; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; Craft; Jewellery; Situated Making; Noticing; Care; Empathy; Postindustrial; World Wide Workshop;

    Abstract : In my research, I consider craft as a discipline that is extremely elastic in terms of propositions and positions. Today craft exists in a highly dynamic space — what I will refer to as the World Wide Workshop — and is essential for noticing, caring, mending and negotiating the complex relationships that individuals and communities have with their sociopolitical, economic and natural environment.
