Playing with Derivation Modes and Halting Conditions
In the area of P systems, besides the standard maximally parallel derivation
mode, many other derivation modes have been investigated, too. In this paper, many
variants of hierarchical P systems and tissue P systems using different derivation modes
are considered and the effects of using di erent derivation modes, especially the maximally
parallel derivation modes and the maximally parallel set derivation modes, on the
generative and accepting power are illustrated. Moreover, an overview on some control
mechanisms used for (tissue) P systems is given.
Furthermore, besides the standard total halting mode, we also consider different halting
conditions such as unconditional halting and partial halting and explain how the use
of different halting modes may considerably change the computing power of P systems
and tissue P systems
The DBSCAN Clustering Algorithm on P Systems
We show how to implement the DBSCAN clustering algorithm (Density
Based Spatial Clustering of Applications with Noise) on membrane systems using evolution
rules with promoters and priorities
Town of Hampton Stormwater Management PREP Natural Resources Outreach Coalition Grant Final Project Report
PREP provided $3,500 towards the project which was matched by municipal funds to pay for consulting advice on improving the regulations. The Planning Board provided exceptional in-kind match on the project, with many hours of work spent by a volunteer engineer serving on the Board. On February 12th 2009, Hampton’s Innovative Land Use Team, in coordination with NROC, hosted a community workshop on stormwater issues that was well attended by municipal officials, town staff, and members of the public. After many revisions, the Planning Board formally adopted the approved stormwater management provisions into the town site plan and subdivision regulations at their July 2009 meeting
