In this study, the contributions of light scattering and extra-loss mechanisms to total losses differential mode attenuation guided modes are quantified for three different few-mode fibers. The tested fibers have same modal content but refractive index profiles, namely step, trapezoidal parabolic. It is demonstrated that a profile good compromise between low attenuation, while maintaining large...

Abstract Numerous research papers and several engineering applications have proved that the fuzzy set theory is an intelligent effective tool to represent complex uncertain information. In multi-criteria decision-making (fuzzy MCDM) methods, information system control-theoretic models, qualitative are extracted from expert’s knowledge as linguistic variables modeled by linear/non-linear numbers...

We present a new mixed finite element method for class of parabolic equations with p-Laplacian and nonlinear memory. The applicability, stability convergence the are studied. First, problem is written in formulation as system one equation Volterra equation. Then, discretized space variable using Lagrangian basis degree r?1. Finally, Cranck-Nicolson trapezoidal quadrature applied to discretize t...

Trapezoidal intuitionistic fuzzy numbers (TrIFNs) express abundant and flexible information in a suitable manner and  are very useful to depict the decision information in the procedure of decision making. In this paper, some new aggregation operators, such as, trapezoidal intuitionistic fuzzy weighted power harmonic mean (TrIFWPHM) operator, trapezoidal intuitionistic fuzzy ordered weighted po...

This paper discusses the energy consumption of three parabolic, trapezoidal, and S-curve profiles when implemented using an embedded system. In addition, it presents alternative methodology for implementing motion controllers Advanced RISC Machine (ARM) microcontroller, which computes trajectory performs control action in hard real-time. We experimented a linear plant composed direct current (D...

We introduce a tractable multi-issue model of electoral competition in which candidates are exogenously committed to particular positions on a subset of issues, while they can choose a sequence of binary positions for the remaining issues to maximize their winning probability. A majorityefficient position is defined as one where a candidate cannot make a majority of the electorate better off, t...

In this paper, a constant speed control of slider-crank mechanisms for machine tools is proposed. A joint-task space hybrid controller based on second-order sliding mode and time-base generator was used to guarantee trajectory tracking complete turn the mechanism crank. switching criterion implemented in order avoid singularities located at two extreme positions slider stroke. trapezoidal profi...

The operating quality of reclamation drainage and irrigation systems depends on the condition their main elements. elements are canals with various profiles, ranging from rectangular to parabolic. most widespread in land a trapezoidal profile. At same time, it is possible note that natural production characteristics quite diverse, this issue especially relevant for geometric parameters canals. ...

in some multi-attribute decision making (madm) problems, various relationships among the decision attributes should be considered. this paper investigates the prioritization relationship of attributes in madm with trapezoidal intuitionistic fuzzy numbers (trifns). trifns are a special intuitionistic fuzzy set on a real number set and have the better capability to model ill-known quantities. fir...

fuzzy newton-cotes method for integration of fuzzy functions that was proposed by ahmady in [1]. in this paper we construct error estimate of fuzzy newton-cotes method such as fuzzy trapezoidal rule and fuzzy simpson rule by using taylor's series. the corresponding error terms are proven by two theorems. we prove that the fuzzy trapezoidal rule is accurate for fuzzy polynomial of degree one and...
