Dantzig-Wolfe decomposition is well-known to provide strong dual bounds for specially structured mixed integer programs (MIPs) in practice. However, the method is not implemented in any state-of-the-art MIP solver: it needs tailoring to the particular problem; the decomposition must be determined from the typical bordered block-diagonal matrix structure; the resulting column generation subprobl...

To exploit the potential of reconfigurable intelligent surface (RIS) in supporting integrated sensing and communication (ISAC), this paper proposes a novel joint active passive beamforming design for RIS-enabled ISAC system consideration target size. First, detection probability is derived closed-form based on illumination power an approximated scattering area target, new concept ultimate resol...

This paper introduces a control strategy to simultaneously achieve asymptotic stabilization and transient frequency regulation of power networks. The command is generated by iteratively solving an open-loop cost minimization problem with stability constraints. To deal the non-convexity constraint, we propose convexification that uses reference trajectory based on system’s current state. We also...

To ensure grid efficiency and reliability, powersystem operators continuously monitor the operational char-acteristics of the grid through a critical process called stateestimation (SE), which performs the task by filtering and fusingvarious measurements collected from grid sensors. This studyanalyzes the vulnerability of the key operation module, namelyAC-based SE, agai...

Unstructured grids are extensively used in modern computational solvers and, thus, play an important role in scientific visualization. They come in many different types. One of the most general types are non-convex meshes, which may contain voids and cavities. The lack of convexity presents a problem for several algorithms, often causing performance issues. One way around the complexity of non-...
