Fuzzy traversability index: A new concept for terrain-based navigation

Homayoun Seraji
2000 Journal of Robotic Systems  
A set of fuzzy navigation rules is developed using the Fuzzy Traversabili t y Index to guide the robot toward the safest and the most traversable terrain.  ...  The Traversability Index is expressed b y fuzzy sets that quantify the suitability of the terrain for traversal based on its geometrical and physical properties, such as slope, roughness, and hardness.  ...  This data is then used to evaluate the Traversability Index based on the fuzzy rules given in Table lb .  ...

Bacterial Uniformity Index

William Firth Wells
1921 Journal - American Water Works Association  
The greater the degree of uniformity of the results the more nearly do the arithmetical and geometrical means approach equality, arid the more nearly does the ratio approach unity.  ...  The rule for obtaining the median value of the results which is, therefore, the geometric mean, called the B. coli index, becomes: Revert dilutions and apply Phelps’ method.  ...
