this paper concerns the problem of robust stabilization of uncertain fractional-order non-autonomous systems. in this regard, a single input active control approach is proposed for control and stabilization of three-dimensional uncertain fractional-order systems. the robust controller is designed on the basis of fractional lyapunov stability theory. furthermore, the effects of model uncertainti...

This paper presents the results of an experiment comparing mouse, penand touch-inputs in computerized figural creativity test. The results show no statistically significant differences in creativity scores obtained by participants using mentioned devices as computer input methods. The results indicate that creativity testing can be introduced to a variety of modern computer devices with insigni...

The common use of mobile terminals is for text input. However, mobile terminals cannot be equipped with sufficient amount of keys because of the physical restrictions. To solve this problem we developed an input method using surface electromyogram (sEMG), treating arm muscle movements as input signals. This method involves no physical keys and can be used to input Japanese texts. In our experim...
