Experiments were conducted to measure the dendrite tip growth velocities of equiaxed dendritic crystals settling in an undercooled succinonitrile (SCN)-acetone melt. The tip velocities were measured as a function of the settling speed of the crystal and the Eulerian angle between the dendrite arms and the flow direction relative to the crystal. The average of the measured tip growth velocities ...

Experiments of particle-laden inclined film flow [Zhou, Dupuy, Bertozzi, and Hosoi, Phys. Rev. Lett. 94 (2005)] have displayed different settling behaviors depending on the particle concentration φ and angle of inclination θ, in which particles accumulate on the substrate or near the advancing contact line, or remain mixed. Zhou et al. presented a lubrication model that captures the qualitative...

The effect of the type of oil, types of alcohol and the alcohol concentration on the settling behaviour of glycerol during biodiesel production is discussed in the current paper. Biodiesel production was performed by transesterification using 0.58 % sodium hydroxide (NaOH) as a basic catalyst at 60°C and 20 min of reaction time. The yield of biodiesel produced in each experiment was separated f...

Computational modeling of pastoralist societies that range as nomads over diverse environmental zones poses interesting challenges beyond those posed by sedentary societies. We present HouseholdsWorld, a new agentbased model of agro-pastoralists in a natural habitat that includes deserts, grasslands, and mountains. This is the paper-of-record for the HouseholdsWorld model as part of a broader i...

We describe a Gröbner basis of relations among conditional probabilities in a discrete probability space, with any set of conditioned-upon events. They may be specialized to the partially-observed random variable case, the purely conditional case, and other special cases. We also investigate the connection to generalized permutohedra and describe a “conditional probability simplex.” 1 Relations...
