The current pretest-posttest quasi-experimental study attempts, firstly, to probe the effects of teaching formulaic sequences (FSs) on the second or foreign language (L2)  learners' oral proficiency improvement and secondly, to examine whether teaching FSs through different resources (i.e. animation vs. text-based readings) have any differentially influential effects in augmenting L2  l...

New techniques for superscalar instruction issuing are presented. It is shown that the data dependency check for both in-order and out-of-order issuing can be performed in O(logw) gate delay using O(w2) primitive gates, where w is the size of the instruction buffer. Furthermore, we present a new counting based technique for assigning instructions to resources. It requires a delay of O(logw+logm...

The analysis in this paper concerns the performance of smart antenna algorithms when used in code-division multiple access (CDMA) wireless communication systems. Complex pseudonoise (PN) spreading, despreading, and pilot-aided channel estimates in the cdma2000 reverse link are some of major characteristics that are different from those in the IS-95 CDMA systems. These different features are inc...

Machine Learning (ML) is traditionally formalized as the study of learning concepts from labeled examples. We are interested in providing a way for a human teacher to interact with a learner using natural instructions, thus allowing the teacher to communicate the relevant domain expertise to the learner without necessarily knowing anything about the internal representations used for learning. W...

Aiming at the existing problems of BCI (brain computer interface), such as single input signal source, low accuracy feature recognition, and less output control instructions, this paper proposes a robotic arm system based on EEG (electroencephalogram) EMG (electromyogram) mixed signals. The flow is follows: Firstly, unilateral left right hand motor imagery collected synchronously. Then signals ...
