ABSTRACT. We consider the iterated function systems (IFSs) that consist of three general similitudes in the plane with centres at three non-collinear points, and with a common contraction factor λ ∈ (0, 1). As is well known, for λ = 1/2 the invariant set, Sλ, is a fractal called the Sierpiński sieve, and for λ < 1/2 it is also a fractal. Our goal is to study Sλ for this IFS for 1/2 < λ < 2/3, i...

In comparison to fuzzy sets, intuitionistic sets are much more efficient at representing and processing uncertainty. Distance measures quantify how the information conveyed by differs from one another. Researchers have suggested many distance assess difference between but several of them produce contradictory results in practice violate fundamental axioms measure. this article, we introduce a n...

This paper reports on a new biomimetic method for modifying carbon fibre surface aiming to improve the bonding between and an epoxy resin system. Inspired by composition of adhesive proteins in mussels, dopamine was utilised process that allowed be self-polymerised onto via ?-? interaction form nano-thin surface-adherent polydopamine (PDA) layer. Graphene oxide (GO) also grafted increase interf...

household food security remains a challenge in south africa. the national government instituted the integrated food security strategy (ifss) programme which identifies household agricultural production as an important element of improving household-level food security. agricultural extension is well positioned to help achieve this aim, but its current contribution is unknown. this study identif...

We develop a representation theory in which a point of a fractal specified by metric means (by a variant of an iterated function system, IFS) is represented by a suitable equivalence class of infinite streams of symbols. The framework is categorical: symbolic representatives carry a final coalgebra; an IFS-like metric specification of a fractal is an algebra for the same functor. Relating the t...

In recent years, q-rung orthopair fuzzy sets (q-ROFSs), a novel and rigorous generalization of the set (FS) coined by Yager in 2017, have been used to manage inexplicit indefinite information daily life with high precision greater accuracy than intuitionistic (IFSs) Pythagorean (PFSs). The characterization measure similarity between q-ROFSs is important, as they applications different areas, in...

In the field of Information Technology (IT) there is an observable trend toward project failure. Although multiple actions have attempted to address this failure trend, they have not impacted the extent of the trend. As the projections for IT investment increase by a magnitude of 3.5% (annual average) and IT project failures report losses in the billions [1], it is anticipated that this trend w...

Interval Type-2 Fuzzy TOPSIS (IT2FTOPSIS) is a useful way to handle Fuzzy Multiple Attribute DecisionMaking (FMADM) problems in a more flexible and intelligent manner. It is very useful due to the fact that it uses Type-2 Fuzzy Sets (T2FSs) rather than Type-1 Fuzzy Sets (T1FSs) to represent the evaluating values and the weights of attributes. Besides, all the linguistic terms are pointed in Typ...

The diversity of medical factors makes the analysis and judgment of uncertainty one of the challenges of medical diagnosis. A well-designed classification and judgment system for medical uncertainty can increase the rate of correct medical diagnosis. In this paper, a new multidimensional classifier is proposed by using an intelligent algorithm, which is the general fuzzy cerebellar model neural...

Matrix resins of carbon fiber-epoxy composites with different numbers of epoxy functional groups were prepared, and their properties were compared to optimize the matrix resin composition. To understand the bonding strengths between the carbon fiber and epoxy resins in monofilaments and micro-sized resin beads, the interfacial shear strength (IFSS) was measured using the microdroplet technique....
