In the high-level operations of computer vision it is taken for granted that image features have been reliably detected. This paper addresses the problem of feature extraction by scale-space methods. This paper is based on two key ideas: to investigate the stochastic properties of scale-space representations, and to investigate the interplay between discrete and continuous images. These investigat

Popular Abstract in Swedish Hur dör neuron (hjärnceller) ? Det finns en mängd anledningar till varför neuron i hjärnan dör, olyckor med skallskador, neurodegenerativa sjukdomar såsom vid Parkinsons eller Alzheimers sjukdom eller efter förgiftningar. Den vanligast anledningen är dock stroke (slaganfall), dvs en akut förlust av blodförsörjningen till en del av hjärnan. Orsaken till stroke kan vara eAfter transient global cerebral ischemia, selected populations of neurons in the brain will die after a period of 2-3 days, a phenomenon termed delayed neuronal death. This is of clinical importance as delayed neuronal death has been found to occur in humans as well. The mechanism that kills a neuron 2-3 days after the initial insult is unclear, but transcriptional steps have been implicated. The

Images of Gustav Vasa from the early 1520s until the 1990s via propaganda, art, monuments and movies.

This book summarizes the project work of the very first batch of participants of Lund University’s international Social Innovation in a Digital Context programme, financed by the Swedish Institute. The programme targets human rights activists in a position from which they can initiate projects of change in their home countries in the area of social innovation. During the programme all participants

The actors in focus here are the citizens and the politicians. We are studying their opinions on two central issues of health-care policy during the period 1981-1991. The aims of the dissertation can be summarised as follows: - to study the compositions of citizens´attitudes to health-care provision and policy - to examine the value of using different methodical approaches when studying health-car

Kritisk granskning av hur pass "revolutionär" 1809 års svenska statsvälvning kan sägas vara.

The note addresses two issues. First assessing the qualities of information systems and semi-autonomous groups requires a theory or model of how to assess. Second, three levels of assessment - a theoretical, a methodological and a practical level - can be distinguished.

A analysis of the subgrid scale flame thickness in the LES framework is presented. The influence of the subgrid flame thickness has been tested numerically on a swirl stabilized flame using a flamelet formulation. The analysis introduces a non-dimensional number a, characteristic for flame and the filter. The values of this number are computed for different LES combustion models and lie in a wide

Gas inside packed food is monitored by a technique named GASMAS, GAs in Scattering Media Absorption Spectroscopy. The sharp gas absorption line in contrast to the broadband bulk absorption enables gas detection in situ. (C)2008 Optical Society of America

The authors utilize different methodologies, disciplinary traditions, and analytical perspectives. Yet, they all draw our attention to the complex and contradictory ways in which men and women from or living in the Gulf are selectively incorporated into a world society. The workshop papers were summarized and form the basis of this proceedings document prepared by Ghalia Gargani, Acting Director o
