Migrativity properties of 2-uninorms over semi-t-operators [PDF]
summary:In this paper, we analyze and characterize all solutions about $\alpha$-migrativity properties of the five subclasses of 2-uninorms, i. e. $C^{k}$, $C^{0}_{k}$, $C^{1}_{k}$, $C^{0}_{1}$, $C^{1}_{0}$, over semi-t-operators.

On the $T$-conditionality of $T$-power based implications [PDF]
summary:It is well known that, in forward inference in fuzzy logic, the generalized modus ponens is guaranteed by a functional inequality called the law of $T$-conditionality.

Hyper-dependence, hyper-ageing properties and analogies between them: a semigroup-based approach [PDF]
In previous papers, evolution of dependence and ageing, for vectors of non-negative random variables, have been separately considered. Some analogies between the two evolutions emerge however in those studies.

Evolution of the Dependence of Residual Lifetimes [PDF]
We investigate the dependence properties of a vector of residual lifetimes by means of the copula associated with the conditional distribution function.

Threshold copulas and positive dependence [PDF]
Starting with a notion of positive dependence View the MathML source and with the family of the lower threshold copulas Ct associated with a bivariate distribution having copula C, we define different notions of positive dependence for C, reflecting the ...

Aging functions and multivariate notions of NBU and IFR [PDF]
For d≥2, let X=(X1, …, Xd) be a vector of exchangeable continuous lifetimes with joint survival function $\overline{F}$. For such models, we study some properties of multivariate aging of $\overline{F}$ that are described by means of the multivariate ...

Interactions between ageing and risk properties in the analysis of burn-in problems [PDF]
Several relevant problems in reliability can be looked at as problems of risk management and of decisions in the face of uncertainty. However, in this frame, the so-called burn-in problem can be seen as a problem of risk taking par excellence.

Aggregation and Related Functions in Fuzzy Set Theory: Dualities and Monotonicity-Based Generalizations [PDF]
We discuss several extensions of binary Boolean functions acting on the domain [0, 1]. Formally, there are 16 disjoint classes of such functions, covering a majority of binary functions considered in fuzzy set theory.

Open problems posed at the eighth international conference on fuzzy set theory and applications [PDF]
summary:Several open problems posed during FSTA 2006 (Liptovský Ján, Slovakia) are presented. These problems concern the classification of strict triangular norms, Lipschitz t-norms, interval semigroups, copulas, semicopulas and quasi- copulas, fuzzy ...

On Univariate and Bivariate Aging for Dependent Lifetimes with ArchimedeanSurvival Copulas [PDF]
summary:Let $\mbox{\boldmath$X$} = (X,Y)$ be a pair of exchangeable lifetimes whose dependence structure is described by an Archimedean survival copula, and let $\mbox{\boldmath$X$}_t= [(X-t,Y-t) \vert X>t, Y>t]$ denotes the corresponding pair of ...
