A better model? Low levels of radiation and health effects
One of the more pivotal issues in facilitating the use of radiation sources—including nuclear power—in the United States (and most of the Western world) is concern about the health effects of low levels of radiation. The current regulatory assumption is that every additional increment of radiation linearly increases the risk of cancer.

Parallelization of the Porsching algorithm for the numerical integration of hydraulic network conservation equations is described, and a theoretical analysis of the performance of the parallelized algorithm on a MIMD-type parallel computer is given. It is shown that good speedup and efficiency of parallel processing can be achieved by using a quasi-MIMD mode of operation employing (a) a master/slave configuration of processors, (b) message passing for data communication, (c) global synchronization of all processors before data communication, (d) a simple time-shared bus with data broadcast facility as the interconnection network, and (e) distributed communication memories for data communication.
