A novel geometric approach for three dimensional object segmentation is presented. The scheme is based on geometric deformable surfaces moving towards the objects to be detected. We show that this model is equivalent to the computation of surfaces of minimal area (local minimal surfaces) in a Riemannian space. This space is deened by a metric induced from the three dimensional image in which th...

We describe a convex relaxation for a family of problems of minimal perimeter partitions. The minimization of the relaxed problem can be tackled numerically, we describe an algorithm and show some results. In most cases, our relaxed problem nds a correct (approximate) solution: we give some arguments to explain why it should be so, and also discuss some situation where it fails.

In this paper, first we examine the usual treatment of temporal information and we recall the main features relative to the temporality analysis in texts. Then we deal with the formal representation of calendar expressions, and we provide a functional approach, based on a categorical representation of ordinals. Finally, an ongoing application providing a help for the reading of long biography i...

For several decades, Restoration studies have noted deficiencies in the treatment of the theology of leadership and of practical ecclesiology. This paper responds to the lack of research linking ecclesiology to organizational design and to the theology of leadership in the Church of Christ tradition by building upon the ecclesiological framework composed of theological tradition, church metapho...

In this note we use a functional approach to the integral to obtain a special case of the Keisler-Fubini theorem; the general case can be obtained with a similar proof. An immediate appUcation is the standard Fubini theorem for products of Radon measures. Similar methods give the Weil formula for quotient groups of compact Abelian groups.

In this note, by considering the notions of the intuitionistic general L-fuzzy automaton and $(alpha, beta)$-language, we show that for any $(alpha, beta)$-language $mathcal{L}$, there exists a minimal intuitionistic general L-fuzzy automaton recognizing $mathcal{L}$.We prove that the minimal intuitionistic general L-fuzzy automaton is isomorphic with threshold $(alpha,beta)$ to any $(alpha, be...

In the history of adoption research, subjective norm mostly remains as the unloved child, being significant in this analysis and not significant in that analysis. Already Davis et al. had to exclude subjective norm of the Technology Acceptance Model due to theoretical and measurement problems. Overall the results of subjective norm as an antecedent for behavioral intention in IS research are qu...
