Abstract: Second-order free riders, who do not owe punishment cost to first-order free riders in public goods games, lead to low cooperation. Previous studies suggest that for stable cooperation, it is critical to have a pool… read more here.

DOI: 10.2514/1.c034720
Abstract: A higher-order free-wake (HOFW) method has been developed to enable conceptual design-space explorations of propeller–wing systems. The method uses higher-order vorticity elements to represent the ... read more here.
