This paper presents a hardware architecture for calculating the city-block and chessboard distance transform on binary images. It is based on applying multiple morphological erosions and adding the result, enabling both processing pixels in raster scan order and a deterministic execution time. Which distance metric to be calculated is determined by the shape of the structuring element, i.e. diamon

Immediate-early genes of the fos and jun families encode proteins that dimerize to form a complex of activator protein 1 and regulate the expression of a number of genes in the nervous system. Ethanol has previously been shown to induce alterations in expression of fos and jun genes in the brain. The present study examined the effects of ethanol on the expression of c-fos, fosB, c-jun, junB and ju
The overarching purpose of this study is to put the experiences of clandestine asylum seekers (rejected asylum seekers who, avoiding deportation, continue to stay in Sweden) at the centre of a critical re-reading of Swedish migration and gender regimes. Further, the study – in dialogue with feminist and postcolonial perspectives – aims to analyse the gendered experiences of migration and clandesti

A new upper bound on the list error probability is presented. This bound is derived by combining the techniques for obtaining the tangential union bound with an improved bound on the error probability with respect to a given list. Connections between the list distance and the eigenvalues of the covariance matrix of the code are studied
Forty years ago, Viterbi published upper bounds on both the first error event (burst error) and bit error probabilities for Viterbi decoding of convolutional codes. These bounds were derived using a signal flow chart technique for convolutional encoders. In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 convolutional enc
The increasing demand on improved reception and high data throughput brings into focus the design of compact multiband antenna terminals with diversity reception capability. In particular, the influence of user on diversity performance is of current interest. In this paper, the diversity performance of compact tri-band antennas (WCDMA850, WCDMA1800 and UMTS 2100) for mobile handsets is evaluated i
In our paper we address a gap in the literature, identified by Silverberg (2007), who claims that we miss an objective criteria for identifying leading sectors associated with technology-induced structural change and measuring their effects on functioning of the economy. In particular, we analyse the role of leading industries in labour reallocation across regions as a mechanism of smoothing regio
