On Connection, Linearization and Duplication Coefficients of Classical Orthogonal Polynomials
(2014-07-16)
In this work, we have mainly achieved the following:
1. we provide a review of the main methods used for the computation of the connection and linearization coefficients between orthogonal polynomials of a continuous variable, moreover using a new approach, the duplication problem of these polynomial families is solved;
2. we review the main methods used for the computation of the connection and linearization coefficients of orthogonal polynomials of a discrete variable, we solve the duplication and linearization ...

Generation Human Body Motion by the Centralized Networks
(2023)
The main goal of the thesis is to describe and study reduced models for efficient simulations of human body motions (HBM). To this end, we propose new coupled oscillator models, which are networks of dynamically coupled elements. These networks consist of a few of centers and many satellites. The centers evolve in time as periodical oscillators with different frequencies. The satellite states are defined via center states by a radial basis function (RBF) networks. To simulate different motions we adjust the parameter ...

Twin Basic Quantum Calculus and its Applications
(2024)
We give in this work some results on twin basic quantum calculus. The (p,q)-derivative, the (p,q)-integral and some (p,q)-Taylor formula are discussed. Next, we introduce and provide several results about (p,q)-Gamma and (p,q)-Beta functions. Some (p,q)-Sturm Liouville problems are introduced and some (p,q)-hypergeometric solutions are obtained. The work ends with the introduction (p,q)-Appell polynomials and some (p,q)-Laplace transforms.
