In fuzzy system, we generally try to measure the qualitative difference of a certain object/ subject. In Physics/ Chemistry discipline there are specific formula to answer the question. But, my point is to get an alternative formula to do the same job via fuzzy system in Applied Mathematics discipline/ soft computing discipline. To tackle with such question the following subtopic may be considered.
Fuzzy logic and Fuzzy set, Degree of fuzziness, Learning experiences, Human perception, Time series analysis
