Systems involving flexible bodies interacting with surrounding fluid flow are commonplace, but are challenging to model numerically on account of their complex geometries and freely moving boundaries. In the present study, we developed an immersed boundary method (IB) for simulating fluid−flexible structure interactions. Our method is based on an efficient Navier-Stokes solver adopting the frac...

These studies examined the role of ontological beliefs about category boundaries in early categorization. Study 1 found that preschool-age children (N= 48, ages 3-4) have domainspecific beliefs about the meaning of category boundaries; children judged the boundaries of natural kind categories (animal species, human gender) as discrete and strict, but the boundaries of other categories (artifact...

We describe a method to numerically model flows through porous media by representing the medium as randomly distributed collection of regularized Stokeslets. establish correspondence between our and Brinkman description media. The provides flexible way treat with complex geometries deforming boundaries. demonstrate it using examples microscale swimmers.

Unmanned aerial vehicles (UAV) are evolving as an alternative tool to acquire land tenure data. UAVs can capture geospatial data at high quality and resolution in a cost-effective, transparent and flexible manner, from which visible land parcel boundaries, i.e., cadastral boundaries are delineable. This delineation is to no extent automated, even though physical objects automatically retrievabl...

We consider the issue of how a flexible musical space can be manipulated by users of an active music system. The musical space is navigated within by selecting transitions between different sections of the space. We take inspiration from pheromone trails in ant colonies to propose and investigate an approach that allows an artificial agent to navigate such musical spaces in accordance with the ...
