Positive solutions for discrete Minkowski curvature systems of the Lane-Emden type

open access: yesOpen Mathematics, 2023
We study the one-parameter discrete Lane-Emden systems with Minkowski curvature operator ΔΔu(k−1)1−(Δu(k−1))2+λμ(k)(p+1)up(k)vq+1(k)=0,k∈[2,n−1]Z,ΔΔv(k−1)1−(Δv(k−1))2+λμ(k)(q+1)up+1(k)vq(k)=0,k∈[2,n−1]Z,Δu(1)=u(n)=0=Δv(1)=v(n),\left\{\begin{array}{ll ...

An Approximate Method for Solving Optimal Control Problems for Discrete Systems Based on Local Approximation of an Attainability Set

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
An optimal control problem for discrete systems is considered. A method of successive improvements along with its modernization based on the expansion of the main structures of the core algorithm about the parameter is suggested.

Discrete Memristive Hindmarsh-Rose Neural Model with Fractional-Order Differences

open access: yesFractal and Fractional
Discrete systems can offer advantages over continuous ones in certain contexts, particularly in terms of simplicity and reduced computational costs, though this may vary depending on the specific application and requirements.

Grand Challenges in Discrete Event Logistics Systems [PDF]

open access: yes, 2010
With the experience of dealing with systems as complex as wafer fabrication plants as well as aerospace spare parts logistics networks, I would consider the following four factors as the greatest contemporary challenges for Discrete Event Logistics ...

Discrete Biochemical Systems Theory

open access: yesFrontiers in Molecular Biosciences, 2022
Almost every biomedical systems analysis requires early decisions regarding the choice of the most suitable representations to be used. De facto the most prevalent choice is a system of ordinary differential equations (ODEs).

Robust control for discrete-time networked control systems

open access: yes, 2010
This paper considers analysis and synthesis of discrete-time networked control systems (NCSs), where the plant has additive uncertainty and the controller is updated with the sensor information at stochastic time intervals.

Discrete-time output feedback sliding-mode control design for uncertain systems using linear matrix inequalities [PDF]

open access: yes, 2011
An output feedback-based sliding-mode control design methodology for discrete-time systems is considered in this article. In previous work, it has been shown that by identifying a minimal set of current and past outputs, an augmented system can be ...
