Trapezoidal operator preserving the expected interval and the support of fuzzy numbers
Journal of Numerical Analysis and Approximation Theory, 2011 The problem to find the trapezoidal fuzzy number which preserves the expected interval and the support of a given fuzzy number is discussed. Properties of this new trapezoidal approximation operator are studied.

Exponentially Convergent Trapezoidal Rules to Approximate Fractional Powers of Operators
Journal of Scientific Computing, 2022 AbstractIn this paper we are interested in the approximation of fractional powers of self-adjoint positive operators. Starting from the integral representation of the operators, we apply the trapezoidal rule combined with a double-exponential transform of the integrand function.

On Approximation of Any Ordered Fuzzy Number by A Trapezoidal Ordered Fuzzy Number [PDF]
Symmetry, 2018 In this paper, the model of imprecise quantity information is an ordered fuzzy number. The purpose of our study is to propose some methods of approximating any ordered fuzzy number using a trapezoidal ordered fuzzy number. The information ambiguity is evaluated by means of an energy measure.

Reducing computational requirement of stability analysis of milling by partial averaging
Manufacturing Review, 2014 The trapezoidal rule and Taylor theorem are used to establish a novel reformulation technique called Partial Averaging (PA). PA is seen to reduce computational time (CT) of computer central processing unit (CPU) without loss of accuracy.
