A model of event driven anticipatory learning is described and applied to a number of attention situations where one or several visual targets need to be tracked while being intermittently occluded. The model combines covert tracking of multiple targets with overt control of a single attention focus. The implemented system has been applied to both a simple scenario with a car that is occluded in a
Many full-reference objective metrics require that the original and the degraded video contain the same number of frames. Most codecs are not able to decode the video properly when the video is subject to packet losses and produce incomplete video files with lower number of frames than the original video. In this paper we present a simple method to reconstruct the degraded videos so that it has th
Popular Abstract in Swedish Akut leverskada och tarmen. Kväveoxids roll, och effekten av arginin- och probiotikatillförsel.Infectious complications with enteric bacteria are common in liver diseases and liver surgery. An increased bacterial translocation from the gut has been proposed as one underlying mechanism. In order to elucidate pathogenetic mechanisms and find possible preventive measures, we manipulated the enteric content and therefore we investigated the role of nitric oxide and the effect of arginine and pr
Nandita Singh and her colleagues look at children’s water rights in India. They argue for the exercise of the right to water by children by analysing the universal normative-legal framework and its difference to the local socio-culturally defined framework. They suggest that defining problems and designing actions only within the normative-legal framework can obscure understanding the critic
The duality principle in robust stabilization problems of rank one is studied. Several scalar examples are solved to illustrate the effectiveness and simplicity of the principle. Robustly stabilizing controllers that are designed by this method are usually of low order

Markov regime switching models are often used to model energy prices. We have applied these to six electricity markets. The seasonal variation is corrected for by using the month ahead forward price as a predictor. This paper extends to the current framework by using Gamma distributed spikes, which improves the fit for most energy markets. Applications on European energy markets are provided with

Pauses in spontaneous speech have a freer distribution than pauses in read texts; however, they are not distributed haphazardly. The results of the present study show that the majority of the perceived pauses in the spontaneous speech material, 73%, occur in one of the following three positions: between sentences, after discourse markers and conjunctions and before accented content words. This is
