A parallel multisplitting method with self-adaptive weightings for solving H-matrix linear systems [PDF]

open access: yesJournal of Inequalities and Applications, 2017
In this paper, a parallel multisplitting iterative method with the self-adaptive weighting matrices is presented for the linear system of equations when the coefficient matrix is an H-matrix.

A method to correct for the effect of blockage and wakes on power performance measurements [PDF]

open access: yesWind Energy Science, 2023
Wind turbine power performance measurements often occur at the perimeter of a wind farm, where the wind flow is subject to blockage effects, which might impact the measured power performance.

Quantum Entropies and Decoherence for the Multiparticle Quantum Arnol’d Cat

open access: yesEntropy, 2023
I study the scaling behavior in the physical parameters of dynamical entropies, classical and quantum, in a specifically devised model of collision-induced decoherence in a chaotic system.

Linear Complementarity Systems [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2000
Summary: The authors introduce a new class of dynamical systems called ``linear complementarity systems''. The time evolution of these systems consists of a series of continuous phases separated by ``events'' which cause a change in dynamics and possibly a jump in the state vector. The occurrence of events is governed by certain inequalities similar to

Output-Based Dynamic Periodic Event-Triggered Control with Application to the Tunnel Diode System

open access: yesJournal of Sensor and Actuator Networks, 2023
The integration of communication channels with the feedback loop in a networked control system (NCS) is attractive for many applications. A major challenge in the NCS is to reduce transmissions over the network between the sensors, the controller, and ...

Identification of Vibration Parameters in a Spacecraft using Nonparametric and Parametric Methods [PDF]

open access: yesModeling, Identification and Control, 1996
This article describes identification of vibration frequencies in a spacecraft. A mathematical model of a simple spacecraft is built in MATLAG code, and after a theoretical overview, this spacecraft model is simulated, using a torque excitation, to ...

FEEDBACK LINEARIZATION OF PIECEWISE LINEAR SYSTEMS [PDF]

open access: yesIFAC Proceedings Volumes, 2005
One of the classical problems of nonlinear systems and control theory is feedback linearization. Its obvious motivation is that one can utilize linear control theory if the nonlinear system at hand is linearizable by feedback. This problem is well-understood for the smooth nonlinear systems. In the present paper, we investigate feedback linearizability

Linear Computation Coding: A Framework for Joint Quantization and Computing

open access: yesAlgorithms, 2022
Here we introduce the new concept of computation coding. Similar to how rate-distortion theory is concerned with the lossy compression of data, computation coding deals with the lossy computation of functions.

A robust state estimator against constant measurement delay based on the sensitivity penalisation of model‐parameter errors for systems with no exogenous inputs

open access: yesIET Radar, Sonar & Navigation, 2021
In this study, a class of linear system, which is with no exogenous input and suffered from constant measurement delay and uncertain model‐parameter errors, is under consideration.

An Aggregation-Based Algebraic Multigrid Method with Deflation Techniques and Modified Generic Factored Approximate Sparse Inverses

open access: yesMathematics, 2023
In this paper, we examine deflation-based algebraic multigrid methods for solving large systems of linear equations. Aggregation of the unknown terms is applied for coarsening, while deflation techniques are proposed for improving the rate of convergence.
