An Efficient Quantum Multi-Collision Search Algorithm

open access: yesIEEE Access, 2020
In this article, we propose an efficient quantum k-collision search algorithm with low quantum memory O(n). The previous quantum k-collision algorithms can not be converted into a low quantum memory k-collision algorithm directly, because the time ...

Symbolic Optimal Control [PDF]

open access: yesIEEE Transactions on Automatic Control, 2019
We present novel results on the solution of a class of leavable, undiscounted optimal control problems in the minimax sense for nonlinear, continuous-state, discrete-time plants. The problem class includes entry-(exit-)time problems as well as minimum time, pursuit-evasion and reach-avoid games as special cases.

Heteroclinic optimal control solutions for attitude motion planning [PDF]

open access: yes, 2013
An analytical attitude motion planning method is presented that exploits the heteroclinic connections of an optimal kinematic control problem. This class of motion, of hyperbolic type, supply a special case of analytically defined rotations that can be ...

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 periodic output feedback control: a continuous-time approach [PDF]

open access: yes, 2007
: This paper addresses the problem of optimal static output feedback control of linear periodic systems. The proposed approach, which allows to deal with both stable and unstable open loop systems, relies on a continuous-time formulation of the control ...

Optimal and sub-optimal control in Dengue epidemics

open access: yes, 2001
This work concerns the application of the optimal control theory to Dengue epidemics. The dynamics of this insect-borne disease is modelled as a set of non-linear ordinary differential equations including the effect of educational campaigns organized to ...
