Intuitionistic fuzzy set （IFS） is a set of 2.tuple arguments, each of which is characterized by a membership degree and a nonmembership degree. The generalized form of IFS is interval-valued intuitionistic fuzzy set （IVIFS）, whose components are intervals rather than exact numbers. IFSs and IVIFSs have been found to be very useful to describe vagueness and uncertainty. However, it seems that little attention has been focused on the clustering analysis of IFSs and IVIFSs. An intuitionistic fuzzy hierarchical algorithm is introduced for clustering IFSs, which is based on the traditional hierarchical clustering procedure, the intuitionistic fuzzy aggregation operator, and the basic distance measures between IFSs： the Hamming distance, normalized Hamming, weighted Hamming, the Euclidean distance, the normalized Euclidean distance, and the weighted Euclidean distance. Subsequently, the algorithm is extended for clustering IVIFSs. Finally the algorithm and its extended form are applied to the classifications of building materials and enterprises respectively.

In this letter, a new conception of strongly extreme stability for delay-differential systems of retarded and neutral type has been first produced. We shall show the respective sufficient conditions to guarantee that there exists the stationary oscillation of the systems, not using the difficult-to-check condition in Yoshizawa’s theorem. When the systems are

This paper presents the investigation on the two-stop-two-slip (TSTS) motions in a dry friction oscillator. Friction is a kind of dissipated force. Simple dry friction oscillator implies complicated stick-slip motions. Due to its nonlinear non-smooth characters, it is difficult to analyze the stick-slip motions. First, TSTS motion is analyzed in this paper. A closed form solution of the TSTS motions is presented. In addition, parameter domain for the motion is studied. In general, there are no explicit solutions to transcendental equation in the closed form solution. However, explicit solutions are possible for special cases. Moreover, Poincare map is structured to analyze the stability of the motions.
