The proposed hybrid osprey‐salp swarm optimization algorithm addresses optimal power flow (OPF) problems in smart grids incorporating solar, hydro, and thermal generators. The algorithm is validated on Institute of Electrical and Electronics Engineers 30‐, 57‐, and 118‐bus test systems across five single and multiobjective OPF scenarios.

Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.

ABSTRACT International organizations' (IOs) evaluation policies face unprecedented threats from post‐truth dynamics—delegitimization of expertise, nationalist framing against multilateralism, authoritarian overconfidence, and anti‐scientific sentiment. Despite institutional convergence on independence safeguards, methodological standards, and normative
