We present a computational model, based on Attribution theory, of responsibility judgment for negative events. Our model uses Qualitative Process theory to reason over the continuous parameters involved in attribution, avoiding the need for ad-hoc assignment of quantitative values. Qualitative reasoning allows our model to infer relative amounts of responsibility for a situation in a manner tha...

Calculations of sensitivities of future experiments are a necessary ingredient in experimental high energy physics. Especially in the context of measurements of the neutrino oscillation parameters extensive studies are performed to arrive at the optimal configuration. In this note we clarify the definition of sensitivity as often applied in these studies. In addition we examine two of the most ...

We introduce an empirical Bayesian procedure for the simultaneous segmentation of an observed motion field and estimation of the hyper-parameters of a Markov random field prior. The new approach approach exhibits the Bayesian appeal of incorporating prior beliefs, but requires only a qualitative description of the prior, avoiding the requirement for a quantitative specification of its parameter...

lineaments are the most important phenomena of geological exploration of hydrocarbon reservoirs . concepts in order to map the contours of land need so much time and money. one of the most famous methods in lineaments extraction is satellite image processing. in this paper, an overview of lineament extraction methods and a new method based on canny edge detection algorithm is raised. the result...

We consider leptogenesis induced by soft supersymmetry breaking terms (“soft leptogenesis”), in the context of the inverse seesaw mechanism. In this model there are lepton number (L) conserving and L-violating soft supersymmetry-breaking B-terms involving the singlet sneutrinos which, together with the – generically small– L-violating parameter responsible of the neutrino mass, give a small mas...

Population ageing is a major issue for society in the next years, especially because of theincrease of dependent people. The limits in specialized institutes capacity and the wish of theelderly to stay at home as long as possible explain a growing need for new specific at home services.Technologies can help securing the person at home by detecting falls. They can also help in th...

introduction: the aim of this study was to evaluate the effect of successful kidney transplantation (kt) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-spect) in patients suffering from end-stage renal disease. ...
