  2. 1. World oil supply in the 21st century : A bottom-up perspective

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

    Abstract : Oil-fuelled progress was a defining feature of the 20th century, and still today, oil remains the world’s largest primary energy source. Yet, oil is a non-renewable and carbon-intensive resource, either depletion or resulting carbon emissions will ultimately limit its use. READ MORE

    Abstract : The field of nanofabrication is vast, and there are many methods available to facilitate the fabrication of different types of structures. Nanostructured materials make up critical infrastructure in fields like medical technology, energy storage and production, computer science and more. READ MORE

  6. 4. Visual Attention in Active Vision Systems : Attending, Classifying and Manipulating Objects

    Author : Babak Rasolzadeh; Jan-Olof Eklundh; Ales Leonardis; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; visual attention; saliency map; compter vision; robotics; active vision; machine learning;

    Abstract : This thesis has presented a computational model for the combination of bottom-up and top-down attentional mechanisms. Furthermore, the use for this model has been demonstrated in a variety of applications of machine and robotic vision. READ MORE

  7. 5. Solvable Topological Boundaries

    Author : Flore Kiki Kunst; Emil Bergholtz; Henning Schomerus; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : The hallmark of topological phases of matter is the presence of robust boundary states. In this dissertation, a formalism is developed with which analytical solutions for these states can be straightforwardly obtained by making use of destructive interference, which is naturally present in a large family of lattice models.
