The objective of this work is to automatically recognize faces from video sequences in a realistic, unconstrained setup in which illumination conditions are extreme and greatly changing, viewpoint and user motion pattern have a wide variability, and video input is of low quality. At the centre of focus are face appearance manifolds: this thesis presents a significant advance of their understand...

background: initiating a national poisoning information centre (pic) in estonia took about 12 years of challenging work on research, training and attracting governmental support and funding. in this study we described the establishment process and the profile of phone calls in the first year which the pic started to be available full time (24h/day 7days/week).  methods: this was a descriptive r...

Abstract Let $$\Gamma $$ Γ be a finite group acting on Lie G . We consider class of extensions $$1 \rightarrow \hat{G} \Gamma 1$$ 1 → G ^ defined by this action and 2-cocycle with values in the ...

Let G(Fq) be the group of rational points of a split connected reductive group G over the finite field Fq . In this paper we show that the category of representations of G(Fq) which are finite direct sums of unipotent representations in a fixed two-sided cell is equivalent to the centre of a certain monoidal category of sheaves on the flag manifold of G×G. We also consider a version of this for...

In applications of centre manifold theory we need more flexible error estimates than that provided by, for example, the Approximation Theorem 3 by Carr [4, 6]. Here we extend the theory to cover the case where the order of approximation in parameters and that in dynamical variables may be completely different. This allows, for example, the effective evaluation of low-dimensional dynamical model...
