A constitutive theory is proposed, which possesses the possibilities of modelling all the important features or the behaviour or frictional materials such as: influence of all three stress invariants, coupling between deviatoric and volumetric response, dilatancy, softening, and different behaviour in loading and unloading. The basic constitutive assumptions are relations between properly defined
Abstract submitted to ISEE 2012 Theme: The Political Economy of Green Development By Rikard Warlenius PhD Candidate Human Ecology Division Lund University, Sweden 2011.11.24 Calculating Climate Debt. A Comparison and a Proposal The notion of climate debt has invoked widespread interest in the last few years. First conceptualized in 1999 within the Millennium movement for (financial) debt cancella
In the study of distributed systems, it is of fundamental interest to understand how specifications on local components and interconnections influence global properties of the system. In this paper, we consider linear continuous time systems described by sparse matrices. Properties of interest are stability and quadratic performance specifications such as passivity and input-output gain. In partic
Popular Abstract in Swedish Denna avhandling fokuserar på effekterna av spin-ban växelverkan (SBV) i nanometerstora ferromagnetiska metallpartiklar. SBV kan betraktas som en interaktion mellan två magnetiska moment, varav det ena utgörs av elektronens spin och det andra är orsakat av elektronens egen banrörelse. Banrörelsens bidrag bygger på faktumet att ett magnetiskt moment genereras av elektrisThis thesis is a theoretical investigation of the effects of spin-orbit (SO) interactions in ferromagnetic metal nano-particles. Part I of the thesis is devoted to an elementary introduction of the research field, including recent experimental advances which partly motivated the work presented here. At the core of the thesis lie four original papers, collected in Part II, which are presented and s
In this third chapter of my study on Bruno K. Öijer and intermediality, discuss and describe the research field of intermedia studies. I problematise the dominant focus on art in intermedia studies. I also suggest that intermedial research should be more (than what is the case today) connected to communication theory. I elaborate on some of the most common models and typologies for intermedia stud
