Keywords: fuzzy Banach space, fuzzy analysis, fuzzy variable, completeness, fixed point, Hyers-Ulam stability, quintic functional equation
Moslehian et al. investigated the fuzzy stability problems for the Cauchy additive functional equation and\nthe Jensen additive functional equation in fuzzy Banach spaces.\n\nUsing the fixed point met...
Faculty of Mechanical Engineering, University of Helsinki, Finland
Keywords: Fatigue, Random Vibrations, pitman arm, Road Roughness, PSD function.
Road roughness is a broad term that incorporates everything from potholes and cracks to the random deviations that exist in a profile. To build a roughness index, road irregularities need to be measur...
