This paper investigates existence and uniqueness results for the first order fuzzy integro-differential equations. Then numerical results and error bound based on the left rectangular quadrature rule, trapezoidal rule and a hybrid of them are obtained. Finally an example is given to illustrate the performance of the methods.

In this paper a numerical algorithm is proposed for the computation of the Fourier Transform. The quadrature rule developed is based on the Whittaker Cardinal Function expansion of the integrand and a certain Conformai Map. The error of the method is analyzed and numerical results are reported which confirm the accuracy of the quadrature rule.

This work is devoted to the study of integration with respect to binomial measures. We develop interpolation quadrature rules and study their properties. Applying a local error estimate based on null rules, we test two automatic integrators with local quadrature rules that generalize the five points Newton Cotes formula.

In this work, a hardware efficient algorithm for sequential in-phase (I) and quadrature (Q) imbalance (IQ imbalance) and carrier frequency offset (CFO) compensation under chromatic dispersion (CD) and phase noise (PN) environment is proposed. Two identical orthogonal frequency division multiplexing (OFDM) symbols, which are namely training sequences (TSs), are used to acquire CFO and IQ imbalan...

In their paper published in 1952, Hestenes and Stiefel considered the conjugate gradient (CG) method an iterative method which terminates in at most n steps if no rounding errors are encountered [24, p. 410]. They also proved identities for the A-norm and the Euclidean norm of the error which could justify the stopping criteria [24, Theorems 6:1 and 6:3, p. 416]. The idea of estimating errors i...

This note studies the approximation error of a local projection operator on polynomials of total degree k defined on quadrilaterals. Among other applications, this projection operator permits to derive easily error estimates for quadrature formulas.

Jianhao Zhang, Jinda Cai Numerical Control And Display Lab, USST, 200093 ShangHai,China Emails:[email protected] Abstract:A method of compensation is proposed based on the error model with the robot’s parameters of kinematic structure and the joint angle. Using the robot kinematics equation depending on D-H algorithm, a kinematic error model is deduced relative to the end actuator of the robot, ...

Differential space time block coding (STBC) achieves full spatial diversity and avoids channel estimation overhead. Over highly frequency-selective channels, STBC is integrated with orthogonal frequency division multiplexing (OFDM) to achieve high performance. However, low-cost implementation of differential STBC-OFDM using direct-conversion transceivers is sensitive to In-phase/Quadrature-phas...
