Komposit dapat menghasilkan material ringan dengan kekuatan tinggi yang diaplikasikan pada bilah turbin angin. Epoksi adalah salah satu kelompok polimer termoset sering digunakan sebagai matriks komposit karena sifat mekanik nya baik. Serat karbon merupakan penguat paling diminati luar biasa, menjadikannya ideal dalam canggih. Namun serat memiliki permukaan halus dan inert adhesi antarmuka lema...

For any self-similar measure $\mu$ in $\mathbb{R}$, we show that the distribution of is controlled by products non-negative matrices governed a finite or countable graph depending only on IFS. This generalizes net interval construction Feng from equicontractive type case. When satisfies weak separation condition, prove this directed has unique attractor. allows us to verify multifractal formali...

ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(pan)-based carbon fiber. the surface characteristics of carbon fibers were characterized by x-ray photoelectron spectroscopy (xps). the interfacial properties of carbon fiber reinforced polyamide 6 (cf/pa6) composites were investigated by means of the single fiber pull-out tests. as a result, it...

One theme in noncommutative geometry is the recovery of classical geometric data from operator algebraic descriptions of various spaces, formalized through the concept of a spectral triple. This is defined below but, roughly speaking, consists of a C-algebra acting on a Hilbert space, giving co-ordinates for the space, and a Dirac operator, which encodes geometric information. As a prototypical...

Abstract Orthopair fuzzy sets are in which every element is represented by a pair of values the unit interval, one refers to membership and other non-membership. The different types orthopair given literature distinguished according proposed constrain for non-membership grades. aim writing this manuscript familiarize new class called “(2,1)-Fuzzy sets” good enough control some real-life situati...

The optimization of fiber-matrix adhesion is a persistent challenge in any fiber-based composite materials. Usually, commercial sizing agents are applied to carbon fiber surfaces, but these unknown complex mixtures proprietary nature. Here, naturally derived terpenes, borneol and terpeniol, were chemically modified used as for fibers. To tailor the surface interactions, fibers possessing enrich...

In this work, the carbon fibres (CFs) surfaces were modified via sizing and coated with a very thin layer of complex formulation including nanotubes (CNTs). A push-out method was developed based on nanoindentation to assess interfacial shear strength fibre/matrix. The mechanical properties such as indentation hardness, reduced modulus, displacement creep composite evaluated by means Oliver-Phar...

A shortest path problem is a practical issue in networks for real-world situations. This paper addresses the fuzzy shortest path (FSP) problem to obtain the best fuzzy path among fuzzy paths sets. For this purpose, a new efficient algorithm is introduced based on a new definition of ideal fuzzy sets (IFSs) in order to determine the fuzzy shortest path. Moreover, this algorithm is developed for ...

The intuitionistic hesitant fuzzy set (IHFS) is an enriched version of sets (HFSs) that can cover both (FSs) and (IFSs). By assigning membership non-membership grades as subsets [0, 1], the IHFS model handle situations more proficiently. Another related theory pair analysis (SPA), which considers certainties uncertainties a cohesive system represents them from three aspects: identity, discrepan...

Abstract Picture fuzzy set (PFS) is a direct generalization of the sets (FSs) and intuitionistic (IFSs). The concept PFS suitable to model situations that involve more answers type yes, no, abstain, refuse. In this study, we introduce novel picture (PF) distance measure on basis operation functions membership, non-membership, neutrality, refusal, upper bound function membership two PFSs. We con...
