Utgångspunkten för denna behandling av Kristofferbilden är dess mellanställning, mellan representationsbild i Panofskys betydelse och legendserie, dess visande av en handling i en enda bild, och att grtaden av handling i bilden tycks skifta mellan olika perioder. Jag uppfattar handlingen som ett attribut, och söker utforska hur det blivit så, och varför just i detta fall. Eftersom handlingen i sig

Network re-optimization is a process that must be triggered periodically in order to improve the inefficient resource allocation of online routing heuristics due to the uncertainty of online lightpath demand arrivals and departures. Network re-optimization involves two tasks: a) finding new lightpaths for a (sub)set of current demands, i.e. rerouting, and b) migrating the current traffic to the ne

Popular Abstract in Swedish Populärvetenskaplig sammanfattning (Popularised summary in Swedish) Beta-microseminoprotein är ett äggviteämne (protein) som först hittades i sädesvätska (seminalplasma). Det är inte känt vad det har för funktion. Man känner i dag inte till någon som har brist på Beta-microseminoprotein eller någon sjukdom som beror på Beta-microseminoprotein. Den genetiska arvsmassan Human Beta-microseminoprotein is a 94 amino acid protein with 10 cysteins present in seminal plasma and on many mucosal surfaces in the body. The function of the protein is unknown. The purpose of this investigation was to study the distribution of Beta-microseminoprotein in the human body, especially in the stomach. The latter was studied under both normal and pathological conditions. A radioimmu

In the mid 2000s the oil and gas industry was hit by what might be best described as a ‘wall of cash’ as oil prices successively reached new record levels and access to external financing improved greatly. In this article we investigate what this sudden abundance of liquidity implied for the investment-cash flow relationship, the interpretation of which continues to generate controversy in the fin

The technical infrastructures of the society are becoming more and more interconnected and in-terdependent, i.e. the function of an infrastructure influences the function of other infrastructures. Distur-bances in one infrastructure therefore often traverse to other dependent infrastructures and possibly even back to the infrastructure where the failure originated. It is becoming increasingly impo

Ion beam methods are used to analyse material (Ion Beam Analysis, IBA) and to modify the target (Ion Beam Modification of Materials, IBMM). In this thesis, ion beams have been used in various IBA techniques to investigate the surface nanometre structures, and also in an ion beam synthesis (IBS) technique to form thin films and to modify material properties. The work is divided into two main parts:

In this paper, a customized image convolution processor with three level memory hierarchy is implemented on Xilinx VirtexE FPGAs. Due to its fully pipelined datapath for calculations and streamlined data flow architecture, the processor has the performance close to that of TI highest performance C64x processor at less than 1/8 of the clock frequency with substantial I/O bandwidth reductions.

Popular Abstract in Swedish I Big Bang, då vårt Universum skapades, bildades i princip endast de två lättaste grundämnena, väte och helium. Alla andra grundämnen har skapats, och skapas fortfarande, i olika typer av stjärnor under olika utvecklingsfaser. Detta betyder att precis alla atomer, förutom väte och helium, som bygger upp alla saker, växter, djur och människor i vår omgivning, har bildatsDisregarding the small primordial traces of the lightest elements, all metals have been formed in stellar processes, which means that the relative amount of metals in the Universe increases for every stellar generation. This build-up of elements is called chemical evolution and might be used both to constrain stellar models as well as understanding the formation and evolution of stellar population
