Quantizers play a critical role in digital signal processing systems. Recent works have shown that the performance of acquiring multiple analog signals using scalar analog-to-digital converters (ADCs) can be significantly improved by prior to quantization. However, design such hybrid quantizers is quite complex, and their implementation requires complete knowledge statistical model signal. In t...

Different methods of language teaching have tried to help EFL learners to develop good language skills based on their various perspectives. Research findings have underscored the effect of using task types in promoting language skills in terms of accuracy in written discourse. Therefore, this study set out to investigate whether there is an evidence of correct use of simple past tense (Accuracy...

this study investigated the effect of sequencing tasks from simple to complex along +/- reasoning demands on fluency in writing task performance of english as foreign language (efl) learners. the participants of this study included 90 intermediate efl learners from three intact class divisions at the islamic azad uni- versity, shahr-e-qods branch. they were distributed in three groups: experime...

Task and model-based design techniques support the design of interactive systems by focusing on the use of integrated modelling notations to support design at various levels of abstraction. However, they are less concerned with examining the nature of the design activities that progress the design from one level of abstraction to another. This paper examines the distinctions between task and mo...

Task difficulty across different macro-genres continues to remain among less attended areas in second language development studies. This study examined the correlation between task difficulty across the descriptive, narrative, argumentative, and expository macro-genres. The three components of task difficulty (i.e., code complexity, cognitive complexity, and communicative stress) were also comp...
