Stochastic fuzzy differential equations with an application
In this paper we present the existence and uniqueness of solutions to the stochastic fuzzy differential equations driven by Brownian motion. The continuous dependence on initial condition and stability properties are also established. As an example of application we use some stochastic fuzzy differential equation in a model of population dynamics.

Sufficient conditions for a T-partial order obtained from triangular norms to be a lattice
For a t-norm T on a bounded lattice , a partial order was recently defined and studied. In [11], it was pointed out that the binary relation is a partial order on , but may not be a lattice in general. In this paper, several sufficient conditions under which is a lattice are given, as an answer to an open problem posed by the authors of [11]. Furthermore, some examples of t-norms on such that is a lattice are presented.
Sum and product of the modified real fuzzy numbers
Sum of observables in fuzzy quantum spaces
We introduce the sum of observables in fuzzy quantum spaces which generalize the Kolmogorov probability space using the ideas of fuzzy set theory.
Synthesis of membership functions to determine a radius of influence.
In this work we study the synthesis of membership functions when they have been calculated from a set of observations according to the definition of (Zhang, 1993). The results obtained have been used to determine the radius of influence of a tramp for Podarcis lilfordi (a kind of saurians) in the island of Cabrera (Balearic Islands). The measure of this radius was used in a later work to estimate the density of these saurians in the island.
