This paper proposes an auto-focus Instruction function. The function is derived from Ostu segmentation. It uses class variance of segmentation result to instruct auto-focus process. Compare with the exist functions, class variance function need a small calculation mount. It is immunity to jam coming from camera and other inspection. It responses in a wide object distance range. And the value ch...

this study aims to compare the effects of four types of ffi on second language vocabulary learning. to do so, the study adopted a quasi-experimental pretest-posttest design, including five groups, each receiving a distinct treatment. the participants were 80 fourth-grade male students ranging in age from 17 to 19. before the treatment phase, the participants took a researcher-made test of vocab...

Subleq (Subtract and Branch on result Less than or Equal to zero) is both an instruction set and a programming language for a One Instruction Set Computer (OISC). We describe a hardware implementation of an array of 28 one-instruction Subleq processors on a low-cost FPGA board. Our test results demonstrate that the computational power of our Subleq OISC multi-processor is comparable to that of ...

This study investigated the effectiveness of incidental focus on form in promoting second language development in text-based live chats. Sixteen college-level Taiwanese English language learners were partnered with American college students to complete two communicative tasks via synchronous chats on Instant Messenger. Language-related episodes (LREs) were identified and used as a basis for ind...

the aim of the current study was to examine the effect of metacognitive instruction on efl learners’ metacognitive awareness of listening strategies, listening comprehension, and oral language proficiency. fifty students of two upper-intermediate english courses participated in the study and were sampled as the experimental and control groups. for sixteen weeks the experimental group participat...

A key advantage of SIMD (Single Instruction stream, Multiple Data stream) architectures is that synchronization is effected statically at compile-time, hence the execution-time cost of synchronization between “processes” is essentially zero. VLIW (Very Long Instruction Word) machines are successful in large part because they preserve this property while providing more flexibility in terms of wh...

The current study, setting a two-fold goal, attempted to see whether the preemptive focus on form (FonF) under either planned or unplanned conditions could contribute to increasing lexical diversity in written narratives and, second, to find whether there was a trade-off between the lexical diversity and accuracy. To this end, 32 beginner learners were selected following a Quick Oxford Placemen...
