Over the last century,significant results on the characterization and evaluation of fabric hand have been achieved following the development in science and technology. Due to the lack of knowledge of the human cognitive performances,however,neurocognitive theory of fabric hand is under exploration. As results,the understanding of fabric hand and its physiological mechanism remains rather superficial. From the physiological point of view,this paper reviews the progress of researches on fabric hand and its evaluation techniques. Attempts have been made to clear up some misunderstanding on the evaluation of fabric hand,the fact that the previous suggestion of tactile texture space of fabric,namely primary hand,is contradictory to the conclusions of cognitive psychology and cognitive neurology. It is suggested that the future study on fabric hand and its evaluation technique can only make material progress once the current resear...

Their growth has been strongly influenced by the increasingly large usage of surface mount components, and accelerated by the need for an alternative to cleaning procedures which incorporate CFCs. The ‘no‐clean’ concept is not new, but the very low residue levels now attainable have added an important new dimension in formulation and inspection technologies.

Then gradient descent (GD) and recursive least-squares with forgetting factor (FFRLS) algorithms are employed to optimize the parameters of the IT2FLS. Furthermore, a more efficient type-reduction method, called enhanced iterative algorithm with stop condition (EIASC), is utilized. Finally, an evolutionary interval type-2 TSK fuzzy logic system (EIT2FLS) is developed. The results of applying EIT2FLS to nonlinear systems identification problems demonstrated the superiority of the developed EIT2FLS to existing methods.
