TL;DR: In this article, a sequential selection process in group decision making under linguistic assessments is presented, where a set of linguistic preference relations represents individuals preferences, and a collective linguistic preference is obtained by means of a defined linguistic ordered weighted averaging operator whose weights are chosen according to the concept of fuzzy majority, specified by a fuzzy linguistic quantifier.

TL;DR: It is shown that information is not a locally additive variable in a quantum computation; this property may be used to examine the nature of biological information structures.

TL;DR: The maximum entropy approach to obtaining the weights associated with the ordered weighted averaging (OWA) aggregation operator is discussed and an analytic form for these weights are obtained and some of their properties are described.

TL;DR: Jungck's common fixed point theorem is generalized to fuzzy metric spaces and Grabiec proved the contraction principle in the setting of fuzzy metric Spaces introduced by Kramosil and Michalek.

TL;DR: Some new measures for the calculation of the entropy of a probability distribution based on the ordered weighted averaging operator and some measures of fuzziness associated with a fuzzy set are suggested.

TL;DR: Simulations for multiprogrammed hypercube and 2D-grid topologies confirm the usefulness and suggest superiority of this more general approach to other decentralized algorithms for the environment considered.

TL;DR: A definition of the integral of a fuzzy-valued function is introduced that is only slightly different from the usual one, yet that can be applied to a larger class of functions and that is equivalent to the extension principle for functions of this class.

TL;DR: Two on-line, sliding window segmentation algorithms based on parameter fluctuations and change point localization of the Akaike information criterion are presented and the limiting distributions are derived and the asymptotic threshold values are tabulated for future reference.

TL;DR: In this paper, a basic understanding of the issues in real-time database systems is provided and the research efforts in this area are introduced.

TL;DR: It is shown that no efficient algorithm can solve either variant of the AGM unless P = NP, and several heuristic algorithms leading to approximate solutions are presented, based on probabilistic hill climbing and maximum flow techniques.

TL;DR: It is proved that the sublattice Lfn, of fuzzy normal subgroups with finite range and tip “t” is a modular sublATTice of L, and it is removed all the restrictions on the choice of fuzzynormal subgroups, and the class of all fuzzyNormal subgroups Ln forms the modular sub lattices of L.

TL;DR: This work reviews a proposal for using neural networks as a highly parallel model for general-purpose computing, and shows how to map a number of interesting combinatorial optimization problems from graph theory, VLSI placement, and operations research.

TL;DR: This study provides the details of a large-scale implementation of the Cover-Coefficient-based Incremental Clustering Methodology (C2ICM) and shows that its resource requirements are within practical bounds for most platforms.

TL;DR: The circular fuzzy matrices are defined and some properties of a square fuzzy matrix (such as reflexivity, transitivity, and circularity) are carried out to the adjoint of the matrix.

TL;DR: The complete characterization of weighted maximum and minimum operations as well as the ordered weightedmaximum and minimum is established via stability properties of the operations through functional equations.

TL;DR: The concept of entropy is used to construct multivariate quality-control charts to monitor multivariate variability in a process and two new overall variability measures are defined based on the sample variances and ranges on the variables under consideration.

TL;DR: This paper introduces a new concept, called a temporal module, to resolve another type of mismatch among the constituents of a federation, namely, the mismatch involving different time units used in recording temporal information.

TL;DR: It is proved, among other results, that the set Ct of all t-fuzzy congruences of a group G forms lattice, and also the set Lnt of all those fuzzy normal subgroups, which assume the same value t at e the identity of G, forms a lattice.

TL;DR: The optimal data allocation problem is transferred to an integer linear program subject to various constraints, such as network load capacity and storage capacity of each individual computer, and the application of integer linear programming algorithms (fast in practice) is suggested.

TL;DR: An empirical analysis of some heuristics for the graph thickness problem, i.e., decomposing a graph into the minimum number of planar subgraphs, shows that a randomized heuristic is a practical tool for solving this problem.

TL;DR: A quadratic time solution to the problem of transforming X to Y when the set of edit operations is extended to include the squashing and expansion operations is presented.

TL;DR: This paper analyzes the efficient secondary memory processing of three kinds of window queries, namely, the exist, the report, and the select queries, and proves that for the three queries, both for single feature and for multiple non-overlapping features, the number of accesses is never greater than thenumber of pixels inside the window.

TL;DR: This paper proposes a method for the specifications of fuzzy conceptual knowledge and develops the concepts of fuzzy axiomatic semantics and fuzzy denotational semantics, a generalization of classical semantics.

TL;DR: The definition of a fuzzy left (right) udeal (a fuzzy ideal, a fuzzy bi-ideal, a warm interior ideal) generated by a fuzzy set in semigroups is given.

TL;DR: This work addresses the question of whether a given extended necessity measure on X is induced, through a given implication operator on I, from some normalized fuzzy subset ν of X in the following manner: the measure of μ ϵ IX is the degree of containment of ν in μ, according to the implication.

TL;DR: The proposed transients are perturbed by multiplicative noise, and are embedded in various noise backgrounds to simulate an undersea environment, and the system is shown to be able to classify signals down to -1 dB.

TL;DR: A concurrent object data model for a parallel object-oriented database system, named PRACTIC, and its abstract machine are presented and the performance of one of the proposed parallel query/method execution schemes is measured by simulation on the abstract machine.

TL;DR: It is shown that allnilpotent groups can be characterized in terms of their nilpotent fuzzy subgroups.

TL;DR: Considering various query sizes, query graph shapes, and optimization times, it is shown that Tabu Search almost always obtains better query execution plans than other combinatorial optimization techniques.

TL;DR: The authors determine the optimal biasing density from a constraint class whose controlling parameter is fundamental in the performance analysis of Importance Sampling and shows that the constrained optimal distribution from this class minimizes every statistical distance measure to the global optimal distribution and as a consequence is optimal with respect to a large family of nonlinear cost functions.
