We consider a networked control system where a linear time-invariant (LTI) plant, subject to a stochastic disturbance, is controlled over a communication channel with colored noise and a signal-to-noise ratio (SNR) constraint. The controller is based on output feedback and consists of an encoder that measures the plant output and transmits over the channel, and a decoder that receives the channel
The physical bounds for antennas above a ground plane is analyzed in this paper. Optimal antenna G/Q ratio and Q factor are calculated using convex optimization from stored electric and magnetic energy matrices, obtained from a method of moments solver. Physical bounds for a patch antenna with different heights above a ground plane are investigated. Results are verified using commercially availabl
This paper presents a solution to the problem of pose estimation in the presence of heavy radial distortion and a potentially large number of outliers. The main contribution is an algorithm that solves for radial distortion, focal length and camera pose using a minimal set of four point correspondences between 3D world points and image points. We use a RANSAC loop to find a set of inliers and an i

Den naturliga invändningen mot Ole-Andreas Rognstads kommentar i nummer 3 av ERT till min artikel om re-exportförbud är att min artikeln inte behandlar en konflikt mellan Silhouette och konkurrensrätten och jag påstår inte heller, som Rognstad gör gällande, att senare tids domar ger uttryck för ett nytt rättsläge i förhållandet mellan varumärkesrätten och konkurrensrätten. Syftet med artikeln är,
Agricultural intensification has led to dramatic population declines among many farmland bird species. Negative effects of intensive farming in terms of decreased local habitat quality or structural simplification of farmland landscapes have reduced both reproductive outcome and winter survival of many species. Studies investigating agricultural effects on migrating birds using farmland as stopove
Construction of the MAX IV facility started early this year. The facility will include two storage rings for the production of synchrotron radiation. The 3 GeV ring will house insertion devices for the production of x-rays while the 1.5 GeV ring will serve UV and IR users. Recently, the lattices for the storage rings in the MAX IV facility were updated. In the 3 GeV storage ring the vertical beam
Increasingly, international legal arguments exploit the peculiar nature of obligations erga omnes. This practice raises questions about the precise legal status of norms expressing such obligations relative to other norms of international law. According to an oft-made suggestion, whether a norm is part of the international jus cogens or not, when it expresses obligations erga omnes it is hierarchi
