Similarly to Tychonoff product, we introduce the concept of generalized product topology which is different from the notion of product of generalized topologies in [$\acute{A}$. $Cs\acute{a}sz\acute{a}r$, Acta Math. Hungar. 123 (2009), 127-132] for generalized topology and obtain some properties about it. Besides, we prove that connectedness, ${\sigma}$-connectedness and ${\alpha}$-connectedness are all preserved under this product.
Investigation of Neuropsychological Mechanism of Fabric Smoothness Sensation

Stimuli used in previous reported studies were mostly tailor-made embossed surfaces. Validation of neural signalcoding mechanism to address the touch smoothness in daily life was seldom reported. In this study, 20 types of fabrics werechosen as stimuli. Their physical surface profiles were measured by Fabric Touch Tester. Afterwards three different neuralsignal coding mechanisms of SA1 and PC fibers were applied and modified to predict the perceived neural responses. Thepredicted values were compared to subjective smoothness sensations obtained through psychological measurement. Theresults show that it is essential to in detail characterize the unevenness elements on the surfaces of stimuli. The integratedimpacts from the unevenness elements with different intensities and frequencies demonstrate better prediction capacitiesamong the examined neural coding mechanisms. On the basis of the findings, a neuropsychological prediction model offabrics was built. Another 32 types of fabrics were measured and used to validate the model. Strong correlation between thepredicted and subjective sensory results was observed (F=0.808, p<0.001).
