Extreme value theory is about the distributions of very large or very small values in a time series or stochastic process. This has numerous applications connected with environmental science, civil engineering, materials science and insurance. A rather recent approach for modelling extreme events is the so called peak over threshold (POT) method. The generalised Pareto distribution (GPD) is
In recent years, contact-induced language changes have been hotly discussed (e.g. Heine 2003; Heine and Kuteva 2005), and in this paper, a similar line of argument is presented concerning the Slavic languages, and a similar developmental path is applied to minority languages. Based on analogy, future state of minority languages is predicted.
Some languages in the Indo-European family are know
The high-energy satellite of the L2,3 X-ray emission band in Na, Mg, Al and Si has for a long time been attributed to the decay of an initial state with two holes in the 2p shell. In particular, the satellite threshold has been assigned to an initial (2p2)1D state. It has recently been found that X-ray and Auger data give two different values for the energy of this doubly-ionized state, and attemp
This thesis is about the flight of vertebrates and the studies of different modes of flight. Flight has always fascinated mankind and this fascination gave inspiration for our attempts at flying. Yet there are many different modes of flight among vertebrates and this thesis focuses mainly on the flapping flight of bats and intermittent flight of birds, as well as compares some of the factors conce
Food processing comprises operations such as dilution (changing the concentration), homogenisation (changing the particle size), and subsequent pumping (shearing), among others. It is thus of great interest to gain a better understanding of the mechanisms governing the creation and disruption of structures during these engineering operations, and the way in which they are related to the textural a

Popular Abstract in Swedish Till alla de som har undrat vad det är som jag har hållit på med under alla dessa år men inte vågat att fråga. Jag har arbetat med kloning av gener som kodar för olika enzymer. Enzymer finns i alla levande celler och fungerar som katalysatorer (hjälpare) i olika biokemiska reaktioner. Deras uppgift är att påskynda reaktionshastigheten utan att själva förbrukas i reaktiPart I: Plant peroxidases are useful in many areas of application e.g. as tracer enzymes for clinical applications and in biosensors as well as for industrial purposes like in waste water treatment and bleaching processes. A gene encoding a new, neutral horseradish peroxidase isoenzyme, HRP-n, was isolated. The encoded protein shows only 50% sequence identity with the classical HRP-C and lacks the
In this paper the choices of control variables and control structures are investigated for the Open Plate Reactor. Since the process design is very flexible, it allows many different control structures and variables and it may be non-trivial to find the most suitable choice. Analysis with the Relative Gain Array indicates that the flexible process configuration of the OPR enables a decentrali
