Discretizing the deformation parameter in the su(q)(2) quantum algebra
(Sociedad Mexicana de Fisica, 1998-02-01)
Inspired in recent works of Biedenham [1, 2] on the realization of the q-algebra su(q)(2), We show in this note that the condition [2j + 1](q) = N-q(j) = integer, implies the discretization of the deformation parameter ...
Discrete-Time Modeling and Path-Tracking for a Wheeled Mobile Robot
(Revista Computación y Sistemas; Vol. 13 No. 2, 2009-10-15)
Abstract. The exact discrete-time model of a two wheel differentially driven mobile robot is obtained by direct integration of its continuous-time kinematic model. The discrete-time model obtained is used to design two ...

Discrete approximations for strict convex continuous time problems and duality
(Soc Brasileira Matematica Aplicada & Computacional, 2004-01-01)
We propose a discrete approximation scheme to a class of Linear Quadratic Continuous Time Problems. It is shown, under positiveness of the matrix in the integral cost, that optimal solutions of the discrete problems provide ...

Discretizing the deformation parameter in the suq(2) quantum algebra
(1998-01-01)
Inspired in recent works of Biedenharn [1, 2] on the realization of the q-algebra suq (2), we show in this note that the condition [2j + 1]q = Nq(j) = integer, implies the discretization of the deformation parameter α, ...
Discrete Takagi-Sugeno Fuzzy Models Applied to Control the Knee Joint Movement of Paraplegic Patients
(Ieee-inst Electrical Electronics Engineers Inc, 2020-01-01)
In this manuscript, a method for designing Takagi-Sugeno (T-S) fuzzy discrete-time regulators based on linear matrix inequalities (LMIs) is proposed to control the variation of the knee joint angle movement of paraplegic ...
Lagrangian reduction of nonholonomic discrete mechanical systems
(American Institute of Mathematical Sciences, 2010-03)
In this paper we propose a process of lagrangian reduction and<br />reconstruction for nonholonomic discrete mechanical systems where the action of a continuous symmetry group makes the configuration space a principal ...
The truss‐like discrete element method in fracture and damage mechanics
(Emerald Group Publishing Limited, 2011-12)
Purpose: It is the purpose of this paper to further develop the truss-like discrete element method (DEM) in order to make it suitable to deal with damage and fracture problems. Design/methodology/approach: Finite and ...
Stability estimate for the semi-discrete linearized Benjamin-Bona-Mahony equation
(EDP Sciences, 2021)
In this work we study the semi-discrete linearized Benjamin-Bona-Mahony equation (BBM) which is a model for propagation of one-dimensional, unidirectional, small amplitude long waves in non-linear dispersive media. In ...
