A utomatic grey level thresholding through index of fuzziness and entropy Abstract: Algorithms for automatic thresholding of grey levels (without reference to histogram) are described using the terms 'index of fuzziness' and 'entropy' of a fuzzy sel. Their values are seen to be minimum when the crossover point of an S-function corresponds to boundary levels among different regions in image spac...

I consider production of heavy quarks in pA and AA collisions in the framework of the Color Glass Condensate. I discuss the heavy quark production in pA collisions in a classical approximation which takes into account all multiple rescatterings of a proton in a nucleus. For peripheral collisions, heavy quark production cross section can be written in kT -factorized form. The kT factorization is...

AbSlracl: Algorilhms for providing a quanlitati\e measure of edge ambIguity are described through fuzzy measures in a set. An IOdex is derined whose value IS maximum fOJ a grey lone image and decreases as the fnzzmess In detecting edges decreases. The inherent fuzzifying properly of the S-funclion is found to enable one nOI 10 use the tNT operator for contrasl enhancement and 10 save the time o...

The technology of classical realizability was developed in [15, 18] in order to extend the proof-program correspondence (also known as Curry-Howard correspondence) from pure intuitionistic logic to the whole of mathematical proofs, with excluded middle, axioms of ZF, dependent choice, existence of a well ordering on P (N), . . . We show here that this technology is also a new method in order to...

We construct certain systems of elements in K2 of some CM elliptic curves. When the classnumber of the field of CM is 1, The image of this system under the regulator map forms an euler system in the sense of Rubin [Ru]. §1. Systems of K2 of CM elliptic curves. Let K be an imaginary quadratic field. Take a Hecke character φ of K of type (1,0) and let fφ be its conductor. Let H = K(fφ) be the ray...

At the LHC, the leading partons in the nuclei are expected to interact with the maximal possible strength black disk limit up to transverse momenta of the order of few GeV. We demonstrate that in this limit the densities of the quark gluon systems produced in the central AA collisions in the nucleus fragmentation regions should exceed 300GeV/ f m3 which is at least as high as the densities disc...

We report on the temperature derivative of the resistivity close to the Curie temperature of the reentrant systems mMn 22 at % and a,&Zr 8 at % . Magnetic susceptibility results for the mMn system are also presented. Critical exponents could be deduced from the data. The critical behaviour of systems presenting quenched magnetic disorder is a topic of considerable current interest. In particula...
