Quality improvement is playing the key role in success of a business. Reduction variability main step for quality. Control charts are developed purpose monitoring quality characteristics with aim reducing variability. In many industries instead continuous variable categorical (ordinal) data used to measure interest. Hence developing control techniques ordinal has become recent research focus. p...

in this paper, linear matrix inequality (lmi) approach for synchronization of chaotic fuzzy cellular neural networks (fcnns) with discrete and unbounded distributed delays based on sampled-data controlis investigated. lyapunov-krasovskii functional combining with the input delay approach as well as the free-weighting matrix approach are employed to derive several sufficient criteria in terms of...
