    • A Porous Convection Model for Grass Patterns 

      Thompson, Sally E; Daniels, Karen E (2010-01)
      Spatial ecological patterns are usually ascribed to Turingtype reaction-diffusion or scale-dependent feedback processes, but morphologically indistinguishable patterns can be produced by instabilities in fluid flow. We present ...
    • Stress propagation in locally loaded packings of disks and pentagons 

      Kozlowski, Ryan; Zheng, Hu; Daniels, Karen E; Socolar, Joshua ES
      The mechanical strength and flow of granular materials can depend strongly on the shapes of individual grains. We report quantitative results obtained from photoelasticimetry experiments on locally loaded, quasi-two-dime...
