A Mizuno-Todd-Ye predictor-corrector infeasible-interior-point method for symmetric optimization with the arc-search strategy

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we propose a Mizuno-Todd-Ye predictor-corrector infeasible-interior-point method for symmetric optimization using the arc-search strategy.

Radial Symmetry and Monotonicity of Solutions to a System Involving Fractional p-Laplacian in a Ball

open access: yesAdvances in Mathematical Physics, 2018
In this paper, we study a nonlinear system involving the fractional p-Laplacian in a unit ball and establish the radial symmetry and monotonicity of its positive solutions. By using the direct method of moving planes, we prove the following result.

Some bounds for the Z-eigenpair of nonnegative tensors

open access: yesJournal of Inequalities and Applications, 2019
Tensor eigenvalue problem is one of important research topics in tensor theory. In this manuscript, we consider the properties of Z-eigenpair of irreducible nonnegative tensors. By estimating the ratio of the smallest and largest components of a positive

Optimal and adaptive control of underwater vehicles [PDF]

open access: yesModeling, Identification and Control, 1994
This article contains a continuous-time optimal and adaptive control scheme for underwater vehicles moving in six degrees of freedom. The control scheme is an extension of the algorithm ofJohansson (1990) and a modification of the algorithm found in ...

Optimal control subsumes harmonic control

open access: yesProceedings 2007 IEEE International Conference on Robotics and Automation, 2007
We consider trajectory planning within the frameworks of optimal control and harmonic control. We present a formal evidence, in continuous domain and in a standard discretization, that harmonic control is the limit case of a some optimal control problem in which we make the noise level tend to infinity.
