In previous work, we demonstrated an algorithm that treats a group of robots as a 1-dimensional cellular automaton, which is able to establish formations defined by a single mathematical function. We now extend the algorithm to establish grid formations.

The ergastoplasm (granular endoplasmic reticulum) of parotid acinous cells of the mouse is described with special emphasis on unusual forms of this membranous system. In the majority of the acinous cells the ergastoplasm appeared in sections to consist of a large number of separate flattened cisternae. In some acinous cells, however, the ergastoplasm was disposed as a very small number of large...

the rapid growth in natural gas consumption has increased the need for gas storage, in particular in the form of injection into depleted reservoirs. also, co2 sequestration into the depleted reservoirs has attracted a large attention recently. however, it is important to ensure that the injection pressure is maintained below a certain limit to avoid unsealing the cap rock or reactivation of any...
