Shifted genocchi polynomials operational matrix for solving fractional order stiff system [PDF]

, 2021
In this paper, we solve the fractional order stiff system using shifted Genocchi poly nomials operational matrix. Different than the well known Genocchi polynomials, we shift the interval from [0, 1] to [1, 2] and name it as shifted Genocchi polynomials.

An Operational Matrix Method Based on Poly-Bernoulli Polynomials for Solving Fractional Delay Differential Equations

Computation, 2020
In this work, we derive the operational matrix using poly-Bernoulli polynomials. These polynomials generalize the Bernoulli polynomials using a generating function involving a polylogarithm function.

Operational matrix-based technique treating mixed type fractional differential equations via shifted fifth-kind Chebyshev polynomials

Applied Mathematics in Science and Engineering, 2023
The theory of mixed fractional operators is still an uncovered area in fractional modelling. These multi-sided operators result by combining two fractional derivatives with different kernels, that is, the right-sided Caputo's and the left-sided Riemann ...

Sensorless control of deep-sea ROVs PMSMs excited by matrix converters [PDF]

, 2005
The paper reports the development of model-based sensorless control methodologies for driving PMSMs using matrix converters. In particular, experimental results show that observer-based state-estimation techniques normally employed for sensorless control

Information preserving structures: A general framework for quantum zero-error information [PDF]

, 2010
Quantum systems carry information. Quantum theory supports at least two distinct kinds of information (classical and quantum), and a variety of different ways to encode and preserve information in physical systems. A system's ability to carry information
