Secure Transmission in ISAC Systems Aided by Active STAR‐RIS
IET Communications, Volume 20, Issue 1, January/December 2026.This paper investigates the secure transmission problem in an active simultaneous transmitting and reflecting intelligent reflecting surfaces (STAR‐RIS)‐aided integrated sensing and communication downlink system. Our objective is to maximize the sum secrecy rate by jointly optimizing the base station beamforming vectors, the sensing signal covariance ...

Modified Interior-Point Method for Large-and-Sparse Low-Rank Semidefinite Programs
, 2017 Semidefinite programs (SDPs) are powerful theoretical tools that have been studied for over two decades, but their practical use remains limited due to computational difficulties in solving large-scale, realistic-sized problems.

Single‐Shot Initial Mutual Localization for Micro Aerial Swarms
IET Cyber-Systems and Robotics, Volume 8, Issue 1, January/December 2026.ABSTRACT Initial mutual localization of micro aerial swarms remains a challenging problem and is essential for establishing a common reference frame before coordinated flight. This task is difficult due to the limited scene overlap between nonadjacent drones, as well as sparse and low‐quality feature correspondences in environments with insufficient ...

Collaborative Beamforming for Multi‐Target Localization Using Passive Anchors
Electronics Letters, Volume 62, Issue 1, January/December 2026.A joint collaborative beamforming strategy for passive sensor network is proposed active sensors generate collaborative beam to power up the passive sensors and attain accurate self‐localization. ABSTRACT Using wireless passive sensor nodes as anchors is a cost‐effective way for localization system.

Robust Beamforming for ISAC Systems via Probability of Detection Optimisation
Electronics Letters, Volume 62, Issue 1, January/December 2026.We propose a two‐step robust beamforming design for ISAC that maximises multi‐target detection probability while satisfying multi‐user SINR and per‐antenna power constraints. A sensing‐only Riemannian optimisation on the oblique manifold shapes the transmit covariance, followed by SDR‐based reconstruction to enforce communication guarantees ...

Strong duality in conic linear programming: facial reduction and extended duals
, 2013 The facial reduction algorithm of Borwein and Wolkowicz and the extended dual of Ramana provide a strong dual for the conic linear program $$ (P) \sup { | Ax \leq_K b} $$ in the absence of any constraint qualification.

A Voronoi Diagram‐Based Approach for AC Optimal Power Flow
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper presents a new approach for AC optimal power flow. The proposed approach begins by constructing a Voronoi diagram using a set of initial sample points that represent candidate solutions distributed across the search space. It then iteratively adds new sample points, including: (i) a tentative optimal point obtained via the continuous ...

An Iterative Method for Moving Target Localization Using TDOA and FDOA Measurements
IEEE Access, 2018 For moving targets localization, incorporating frequency-difference-of-arrival (FDOA) measurements in the commonly used time-difference-of-arrival (TDOA) positioning systems will improve performance.
