  2. 6. Bulk-boundary correspondence and biorthogonality in non-Hermitian systems

    Author : Elisabet Edvardsson; Emil Bergholtz; Henning Schomerus; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-Hermiticity; bulk-boundary correspondence; biorthogonal quantum mechanics; skin effect; Theoretical Physics; teoretisk fysik;

    Abstract : In topological insulators, the bulk-boundary correspondence describes the relationship between the bulk invariant -- computed for a system with periodic boundary conditions -- and the number of topological boundary states in the corresponding system with open boundary conditions. This is a well-known property of these systems and is important for predicting how they will behave. READ MORE

  4. 7. Parallelism in Constraint Programming

    Author : Carl Christian Rolf; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Parallelism; Constraint Programming; Parallel Consistency; Parallel Search; Distributed Constraint Programming;

    Abstract : Writing efficient parallel programs is the biggest challenge of the software industry for the foreseeable future. We are currently in a time when parallel computers are the norm, not the exception. Soon, parallel processors will be standard even in cell phones. READ MORE

  5. 8. Estimations of Hydrogeological Properties in Vulnerability and Risk Assessments

    Author : Lars Rosen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; groundwater; Markov; conceptual model; Bayes; risk; vulnerability;

    Abstract : The main objective of this thesis was to evaluate and develop approaches for hydrogeological vulnerability and risk assessments, starting with scant data and updating the results as new information becomes available. This work was performed within three separate projects between 1989 and 1995. READ MORE

  6. 9. Shaping the Meaning of Chinese Music Subcultures

    Author : Yiren Zhao; Sam de Boise; Ulrik Volgsten; David Hesmondhalgh; Örebro universitet; []
    Keywords : HUMANIORA; HUMANITIES; Music subculture; resistance; authenticity; Chinese metal; Chinese rap; Chinese rock; Chinese punk; Beijing music; music affect; Chinese modernity;

    Abstract : This thesis focuses on the meaning of Chinese music subcultures, includingChinese metal, rap, rock, and punk styles; and how is the meaning shaped by Chinese participants in the Chinese context, which is represented by the context of Beijing. This project is motivated by addressing the gaps that exist between dominant Anglo-American subcultural theories and explaining contemporary Chinese individuals’ practices.

  7. 10. CO, CO2 and N2 hydrogenation reactions probed by operando x-ray photoelectron spectroscopy

    Author : David Degerman; Anders Nilsson; Miquel Salmeron; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Operando Catalysis; Hydrogenation reactions; High-Pressure X-Ray Photoelectron Spectroscopy; Syngas; kemisk fysik; Chemical Physics;

    Abstract : Catalytic reactions are essential for generating the chemical products required by the modern society. In particular, reactions related to clean energy storage and generation as well as fertilizer production are facilitated by catalysts. However, the processes are often insufficiently understood at a mechanistic level. READ MORE
