We formulate combined register allocation and instruction scheduling within a basic block as a single optimization problem, with an objective cost function that more directly captures the primary measure of interest in code optimization — the completion time of the last instruction. We show that although a simple instance of the combined problem is NP-hard, the combined problem is much easier t...

Abstract The present study intended, firstly, to investigate the effect of web-integrated instruction on self-regulated learning ability in EFL writing, and secondly, to compare and contrast the effects of paper-based feedback and web-assisted feedback on the self-regulated learning ability. To this end, a quasi-experimental design was applied for both cases. In line with the first objective, ...

indubitably, the efficacy of metalinguistic awareness in improving efl learners’ grammatical knowledge and writing quality has long been an area of great interest in applied linguistics brown (2001). accordingly, the main objective of the present study was to investigate the impact of planned and unplanned focus on form instruction on students’ ability to learn grammar and use it appropriately ...

This study investigated the effectiveness of colligational corpus-based instruction on enhancing the pragmalinguistic knowledge of speech act of request among Iranian intermediate EFL learners. The objective of the study was to find out whether or not providing students with corpora through using colligational instruction had any significant effects on enhancing their pragmalinguistic knowledge...
