A Two-Stage Controller Placement Approach for Software-Defined Networking: Toward Metaheuristic-Driven Multi-Objective Optimization

Software-defined networking (SDN) decouples the control plane from the data plane, enabling centralized network management and programmability. However, as the network scale continues to expand, a single controller becomes a performance bottleneck and a single point of failure. T...

A novel geofoam-geogrid composite for protecting buried pipelines against blast loads

This study investigates the performance of a novel geofoam-geogrid composite in mitigating the impact of surface and subsurface blasts on API-× 65 steel pipelines buried 2 m below ground level. A 3D nonlinear finite element method was employed to analyze the effects of blast char...
