Given fuzzy set A, describing pressure p is higher than 15 mPa, through the membership function: 1 H₁(x)= x > 15, 1+ (x-15)² =0 x ≤ 15, and fuzzy set B, describing pressure p is approximately equal to 17 mPa, with membership function: HB(x) = 1 1+ (x - 17)4 Find the membership function of the fuzzy set C, describing pressure p is higher than 15 mPa and approximately equal to 17 mPa. Use at least four different norms for interpreting AND (see Appendix) and draw all membership functions. Using the data given in Problem 7, find the membership function of the fuzzy set D, describing pressure p is higher than 15 mPa or approximately equal to 17 mPa. Use at least four different norms for interpreting OR (see Appendix) and draw all membership functions. Using the data given in Problem 7, find the membership function of the fuzzy set E, describing pressure p is not higher than 15 mPa and approxi- mately equal to 17 mPa. Use four different norms for interpreting AND (see Appendix) and draw all membership functions.
