This paper presents an adaptive Power System Stabilizer (PSS) using an Adaptive Network Based Vague Inference System (ANVIS). An Adaptive Vague Set Based Controller Power System Stabilizer (AVCPSS) has been evaluated. This AVCPSS is capable of providing appropriate stabilization signals over a broad range of operating conditions and disturbances. A Vague Controller (VC) is synthesized by using ...

The aim of this paper is to further develop the congruence theory on lattice implication algebras. Firstly, we introduce the notions of vague similarity relations based on vague relations and vague congruence relations. Secondly, the equivalent characterizations of vague congruence relations are investigated. Thirdly, the relation between the set of vague filters and the set of vague congruence...

We examine logical systems with generalized quantifiers, for expressing and reasoning about assertions with 'generally'. The primary motivation is a qualitative, rather than quantitative, approach to some vague notions. Assertions and arguments involving notions, such as 'generally', 'most', 'many', etc., occur often in ordinary language and in some branches of science. Filters can be used for ...

Proposing the similarity measures formula between Vague sets E and G. Concluding Vague resistance analysis. The concrete application steps were:1Establishing comprehensive characters set; 2Screening excellent varieties set; 3Extracting theory optimal varieties set; 4The single-value date transformed into Vague date, obtaining different varieties Vague sets; 5Vague resistance analysis 1,the simi...

the present study is an attempt to investigate the use of vague expressions by intermediate efl learners. more specifically, the current study focuses on the structures and functions of one of the most common categories of vague language, i.e. general extenders. the data include a 22-hour corpus of english-as-a-foreign-language conversations. a comparison is also made between this corpus and a ...

We define generalized Frobenius-Schur indicators for objects in a linear pivotal category C. An equivariant indicator of an object is defined as a functional on the Grothendieck algebra of the quantum double Z(C) of C using the values of the generalized Frobenius-Schur indicators. In a spherical fusion category C with Frobenius-Schur exponent N , we prove that the set of all equivariant indicat...

In this paper, by using the notions of ”not belonging” (∈) and ”non quasi-k-coincidence” (qk) of a fuzzy point with a fuzzy set, we define the notion of (∈,∈ ∨ qk)-fuzzy subgroups of a group which is a generalization of fuzzy subgroups and (∈,∈ ∨ q)-fuzzy subgroups. Aslo, we generalized the concept of ∈-level set, (∈ ∨ q)-level set and (∈,∈ ∨ q)level set by using ”not belonging” (∈) and ”non qu...

Let (μα) be a net of Radon sub-probability measures on R, and (tα) be a net in ]0, 1] converging to 0. Assuming that the generalized log-moment generating function L(λ) exists for all λ in a nonempty open intervalG, we give conditions on the left or right derivatives of L|G, implying a vague (and thus narrow when 0 ∈ G) large deviation principle. The rate function (which can be nonconvex) is ob...

Let (μα) be a net of Radon sub-probability measures on R, and (tα) be a net in ]0,+∞[ converging to 0. Assuming that the generalized log-moment generating function L(λ) exists for all λ in a nonempty open interval G, we give conditions on the left or right derivatives of L|G, implying vague (and thus narrow when 0 ∈ G) large deviations. The rate function (which can be nonconvex) is obtained as ...
