Data technology advances have increased in recent years, especially for robotic systems, order to apply data-driven modelling and control computations by only considering the input output signals’ relationship. For a approach, system is considered unknown. Thus, initialization values of play an important role obtain suitable estimation. This paper presents methodology initialize model using pse...

The period doubling Cantor sets of strongly dissipative Hénon-like maps with different average Jacobian are not smoothly conjugated. The Jacobian Rigidity Conjecture says that the period doubling Cantor sets of two-dimensional Hénon-like maps with the same average Jacobian are smoothly conjugated. This conjecture is true for average Jacobian zero, e.g. the onedimensional case. The other extreme...

We present simultaneous pseudo-timestepping as an efficient method for aerodynamic shape optimization. In this method, instead of solving the necessary optimality conditions by iterative techniques, pseudo-time embedded nonstationary system is integrated in time until a steady state is reached. The main advantages of this method are that it requires no additional globalization techniques and th...

in this paper, some results of the chebyshev type integral inequality for the pseudo-integral are proven. the obtained results, are related to the measure of a level set of the maximum and the sum of two non-negative integrable functions. finally, we applied our results  to the case of comonotone functions.

We investigate the performance of several preconditioned Conjugate-Gradient-like algorithms and a standard stationary iterative method (block-line-SOR) on linear systems of equations as they arise from a nonlinear elliptic ame sheet problem simulation. The nonlinearity forces a pseudo-transient continuation process that makes the problem parabolic and thus compacts the spectrum of the Jacobian ...

The subject of this paper is a Jacobian, introduced by F. Lazzeri (unpublished), associated to every compact oriented riemannian manifold whose dimension is twice an odd number. We start the investigation of Torelli type problems and Schottky type problems for Lazzeri’s Jacobian; in particular we examine the case of tori with flat metrics. Besides we study Lazzeri’s Jacobian for Kähler manifold...

We study Jacobian inverse kinematics algorithms for mobile manipulators composed of a nonholonomic mobile platform and a holonomic onboard manipulator. In general, the Jacobian algorithms converge locally, often producing weird end effector and platform trajectories. In the paper we use the existing theory of Newton algorithms in order to improve the quality of convergence of the Jacobian algor...

This paper addresses the synthesis problem of Jacobian inverse kinematics algorithms for stationary manipulators and mobile robots. Special attention is paid to the design of extended Jacobian algorithms that approximate the Jacobian pseudoinverse algorithm. Two approaches to the approximation problem are developed: one relies on variational calculus, the other is differential geometric. Exampl...

This paper describes a comparative study of performance between the estimated image Jacobian that come from taking into account the geometry epipolar of a system of two cameras, and the well known analytic image Jacobian that is utilized for most applications in visual servoing. Image Based Visual Servoing architecture is used for controlling a 3 d.o.f. articular system using two cameras in eye...
