Semidefinite Programming Approaches to Hankel Matrix Approximation and Completion via Primal–Dual Interior‐Point Methods

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
Data completion techniques offer numerous advantages in various fields. However, completing large datasets that must satisfy specific criteria can be challenging, necessitating the use of approximative completion methods. The primary objective of this research paper is to showcase the substantial influence of the initial point selection on the ...

Deep Graph Learning for Rapid End‐to‐End Prestress Determination of Tensegrity and Cable‐Strut Tensile Structures

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
In tensegrity and cable‐strut tensile structure design, determining the initial configuration with suitable prestress distributions that ensure structural stability constitutes a critical design phase. To address the limitations of conventional prestress design methods—specifically, low computational efficiency and difficulty in obtaining feasible ...

Direct Data‐Driven State‐Feedback Control of Linear Parameter‐Varying Systems

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 35, Issue 16, Page 6955-6977, 10 November 2025.
ABSTRACT The framework of linear parameter‐varying (LPV) systems has shown to be a powerful tool for the design of controllers for complex nonlinear systems using linear tools. In this work, we derive novel methods that allow us to synthesize LPV state‐feedback controllers directly from only a single sequence of data and guarantee stability and ...

Hybrid Encoder for Discrete and Continuous Variable QKD

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 8, August 2025.
This work demonstrates a hybrid QKD encoder that bridges the advantages of discrete and continuous variables. Utilizing a self‐compensating iPOGNAC design, the encoder is compatible with space‐based and terrestrial quantum networks. The approach simplifies system complexity, improves stability, and ensures cost‐effective integration, paving the way for

On Gain Scheduling Trajectory Stabilization for Nonlinear Systems: Theoretical Insights and Experimental Results

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 35, Issue 6, Page 2142-2155, April 2025.
ABSTRACT Steering a nonlinear system from an initial state to a desired one is a common task in control. While a nominal trajectory can be obtained rather systematically using a model, for example, via numerical optimization, heuristics, or reinforcement learning, the design of a computationally fast and reliable feedback control law that guarantees ...

Numerical Multiphase Yield Design Modelling of Reinforced Soil Structures: A Focus on the Interaction Between Soil and Inclusions

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 25, Issue 1, March 2025.
ABSTRACT In this contribution, we present the numerical implementation of the multiphase model in the yield design framework and apply it to estimate the ultimate bearing capacity of a foundation subjected to a combination of a vertical loading, a horizontal loading and an overturning moment. As a first step, the two phases and their mutual interaction

Target localization method based on semi-definite relaxation with frequency difference of arrival

open access: yesDianxin kexue
The use of frequency measurements to achieve target positioning is characterized by low cost and high reliability. Using only frequency difference of arrival (FDOA) measurements, a precise localization method for static target position was proposed.

Fine‐grained multi‐path channel estimation and matched reception by single metasurface antenna

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
This paper investigates methods to enhance antenna's channel information extraction capabilities in wireless communications, particularly in challenging multi‐path environments. Focusing on the issues of channel information loss due to multi‐path superposition at the receiver and multi‐path fading during wireless channel propagation, this paper ...
