Finite tolerance, definition

The only apprehension of prospective industrial radiation processors with the nonmeasurability criterion comes from the analogies with the history of pesticide residues in foods U). Pesticides are cleared on the basis of either zero tolerance or finite tolerance, and use is rated as safe for a zero-tolerance pesticide when the residue on foods cannot be measured. However, improvements in measurement techniques with time have changed the definition of zero tolerance, sometimes abruptly. Radiation processors are apprehensive of similar experiences with radioactivity induced in food. 

In all such S-shaped curves the range of x is from - to +oo, so that there is always a finite possibility of negative values of x occurring. In the present case the definition of the current ratio makes values of x below zero meaningless. The error of some 4 percent in the cumulative-probability curve implied by this factor may be tolerable in a given case. 

The rehabdity modeling of fault-tolerant aircraft systems using SyRelAn can be divided into two modeling levels, one mapping the system architecture, the other defining the redundancy management. Therefore the SyRelAn tool uses ReUabdity Block Diagrams for the definition of the nominal system architecture. To map the multi-state behavior of different components Concurrent Finite State Machines are implemented.
