Robust Secure Energy Efficiency Optimization for Active STAR-RIS Assisted ISAC Systems

IEEE Open Journal of the Communications Society
In this paper, we consider the reflecting reconfigurable intelligent surface (STAR-RIS)-assisted integrated sensing and communication (ISAC) system under imperfect eavesdropper channel state information (CSI) and uncertain target angle estimation.

On semidefinite descriptions for convex hulls of quadratic programs

Operations Research Letters
Quadratically constrained quadratic programs (QCQPs) are a highly expressive class of nonconvex optimization problems. While QCQPs are NP-hard in general, they admit a natural convex relaxation via the standard semidefinite program (SDP) relaxation.

Data-Driven Estimation of Transmission Loss Coefficients via Linear and Quadratic Programming Under Linear Constraints

Energies
This paper presents a robust data-driven methodology for estimating transmission loss coefficients (B-coefficients) in power systems using linear and quadratic programming (LP and QP), both of which belong to the family of convex optimization models. The
