We present a computational deenition of the Optimal Color Stimuli surface, which corresponds to the limit of physically realizable surface spectral reeectance functions. We can use this surface to quantify and visualize color space properties, as we demonstrate for the CIE XYZ and L*a*b* spaces, as well as our own neurophysiologically-based NPP space. We then extend the technique to compute a r...

in 1997, fang proposed the concept of boundedness of $l$-fuzzy setsin $l$-topological vector spaces. since then, this concept has beenwidely accepted and adopted in the literature. in this paper,several characterizations of bounded $l$-fuzzy sets in$l$-topological vector spaces are obtained and some properties ofbounded $l$-fuzzy sets are investigated.

By space-fractional (or L evy-Feller) diiusion processes we mean the processes governed by a generalized diiusion equation which generates all L evy stable probability distributions with index (0 < 2), including the two symmetric most popular laws, Cauchy (= 1) and Gauss (= 2). This generalized equation is obtained from the standard linear diiusion equation by replacing the second-order space d...

Abstract We prove the existence of a L 2 -normalized solitary wave solution for Maxwell-Dirac equations in (3+1)-Minkowski space. In addition, Coulomb-Dirac model, describing fermions with attractive Coulomb interactions mean-field limit, we (positive) energy minimizer.

We show that in a large class of supersymmetric models with spontaneously broken B − L symmetry, neutron–antineutron oscillations occur at an observable level even though the scale of B − L breaking is very high, vB−L ∼ 2 × 10 16 GeV, as suggested by gauge coupling unification and neutrino masses. We illustrate this phenomenon in the context of a recently proposed class of seesaw models that so...

Background: In this study, the health risk associated with three types of drinking waters (fissure, underground treated and surrounding waters) from two mines in South Africa were assessed. Materials and Methods: The measurement of the radionuclides concentration was carried out by liquid scintillation counter and alpha spectrometer. The estimated radiological risk pose to the people consuming ...

Various algebraic structures have recently appeared in a parallel way in the framework of Hilbert schemes of points on a surface and respectively in the framework of equivariant K-theory [N1, Gr, S2, W], but direct connections are yet to be clarified to explain such a coincidence. We provide several non-trivial steps toward establishing our main conjecture on the isomorphism between the Hilbert...

For every countable non-limit ordinal α we construct an α-dimensional Cantor ind-manifold, i.e., a compact metrizable space Zα such that indZα = α, and no closed subset L of Zα with indL less than the predecessor of α is a partition in Zα. An α-dimensional Cantor Ind-manifold can be constructed similarly.
