The paper presents a certain class of the mathematical models diagnostic information granules describing fuzzy symptoms-faults relationship. A retrieval system is described as an application expert system. Symptoms and faults are fuzzy, with some scaling symptom-fault concept pair values. These value pairs can be considered intuitionistic sets for space diagnosed objects. In this article, (n-Sc...

This paper is in the form of an essay. It defines fractal tops and code space structures associated with set-attractors of hyperbolic iterated function systems (IFSs). The fractal top of an IFS is associated with a certain shift invariant subspace of code space, whence the entropy of the IFS, and of its set-attractor, may be defined. Given any ordered pair of hyperbolic IFSs, each with the same...

Intuitionistic fuzzy sets (IFSs) have attracted more and more scholars’ attention due to their powerfulness in expressing vagueness and uncertainty. In the course of decision making with IFSs, aggregation operators play a very important role since they can be used to synthesize multidimensional evaluation values represented as intuitionistic fuzzy values into collective values. This paper propo...

We introduce a Fourier-based harmonic analysis for a class of discrete dynamical systems which arise from Iterated Function Systems. Our starting point is the following pair of special features of these systems. (1) We assume that a measurable space X comes with a finite-to-one endomorphism r : X → X which is onto but not one-to-one. (2) In the case of affine Iterated Function Systems (IFSs) in...

This study aimed to develop an extrusion and pultrusion system for producing carbon fiber-filled thermoplastic pellets. The extruder delivers a plastic melt impregnation die in sufficient volume is pulled out along with the fibers. fibers pass sideways stretched condition through spreader pins attached pool, which can then be wetted optimally. wetting effect was also improved by immersing fiber...

The mechanical properties of fiber-reinforced composites are largely dictated by fiber-matrix interactions, where a well-adhered interface is desired. Ultra-high molecular weight polyethylene (UHMWPE) fibers suffer from poor interfacial due to their smooth and inert surface. Therefore, enhancing the such will lead an increased use in structural applications high modulus, tenacity, low density, ...

Abstract Many complex real-world problems have been resolved based on similarity operators under intuitionistic fuzzy sets (IFSs). Numerous authors developed (IFSOs) but with some setbacks, which include imprecise results, omission of hesitation information, misleading interpretations, and outright violations metric axioms operator. To this end, article presents a newly operator IFSs to amelior...

  Uncertainty plays a major role in any project evaluation and management process. One of the trickiest parts of any production project work is its cost and time forecasting. Since in the initial phases of production projects uncertainty is at its highest level, a reliable method of project scheduling and cash flow generation is vital to help the managers reach successful implementation of the ...

Extensive decision-making during the vaccine preparation period is unpredictable. An account of severity disease, younger people with COVID-19 comorbidities and other chronic diseases are also at a higher risk pandemic. In this research article, preference ranking structure for recommended young who have been exposed to effects certain diseases. Multiple Criteria Decision-Making (MCDM) approach...
