We present Surface Evolver computer simulations for two-dimensional (2d) foams in which the contact angle at liquid films and Plateau borders meet is non-zero. determine average coordination number Z of bubbles over a wide range finite angles ? fractions ?. find linear scaling values ? between about 0.07 0.15, corroborating previous data obtained case zero angle. The results highlight importanc...

This paper presents empirical data from the implementation of several algorithms for parallel integer arithmetic on a network of workstations. Algorithms were implemented using Sugarbush, a parallel version of the Maple computer algebra system, which uses C/Linda for parallel operations. The Sugarbush implementation is comprared to a specialized C/Linda implementation. Timings are provided for ...

Human fingers have sufficiently more muscles than joints such that every fingertip force of submaximal magnitude can be produced by an infinite number of muscle coordination patterns. Nevertheless, the nervous system seems to effortlessly select muscle coordination patterns when sequentially producing fingertip forces of low, moderate, and maximal magnitude. The hypothesis of this study is that...

The average inter-wire spacing in aligned nanowire systems strongly influences both the physical and transport properties of the bulk material. Because most studies assume that the nanowire coordination is constant, a model that provides an analytical relationship between the average inter-wire spacings and measurable physical properties, such as nanowire volume fraction, is necessary. Here we ...

We consider planning optimal collision-free motions of two polygonal robots under translation. Each robot has a reference point that must lie on a given graph, called a roadmap, which is embedded in the plane. The initial and the goal are given for each robot. Rather than impose an a priori cost scalarization for choosing the best combined motion, we consider finding motions whose cost vectors ...

The evolution of coordination is an important consideration in living systems. Throughout the natural world examples of coordination can be found. These include fish schooling, birds flocking and animals hunting in packs. This paper examines the issue of coordination and how groups can coordinate their actions in a competitive setting. A number of existing game theoretic representations of coor...
