building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...

during the process of reading, sometimes learners use ineffective and inefficient strategies and some factors may influence their use of strategies. perhaps critical thinking is one of these factors. this study aims to identify those categories of reading strategies that are mostly used by iranian efl learners and to see if there is any significant relationship between the critical thinking abi...

In multiplierless finite impulse response (FIR) filters, the product accumulation block (PAB) could be major contributor to hardware complexity, especially for high-order filters. this paper, an optimization scheme where constant multiplication and PAB are jointly optimized at bit-level is proposed minimize complexity. joint optimization, multiple multiplications (MCM) rearranged into several M...

Recently, wavelet transform has proven to be very effective in medical image compression. So, the choice of wavelet filters is a vital factor that could determine the compression performance. This paper considered the effect of applying different types of wavelet filters belonging to orthogonal and biorthogonal wavelet families with different orders on the panoramic dental x-ray images. In addi...

We describe a simple technique for fabricating non-emissive colour filters based on the sensitisation of a highly porous nanostructured metal-oxide film with a monolayer of dye molecules. Ultrafast electron transfer at the oxide/dye interface induces efficient quenching of photogenerated excitons in the dye, reducing the photoluminescence quantum yield by many orders of magnitude. The resultant...

Data Envelopment Analysis (DEA) technique now widely use for efficiency evaluation of a set of Decision Making Units (DMUs). As regards of the necessity for ranking efficient units different DEA models presented each of which has advantages and rank efficient units from special aspects. Note that all the existing ranking models have disadvantages, as well and there is not a model in which all t...

This paper introduces an iterative algorithm for designing IIR digital filters that minimize a complex approximation error in an sense. The algorithm combines ideas that have proven successful in the similar problem of FIR filter design. We use iterative prefiltering techniques common in applications such as parameter estimation together with an Iterative Reweighted Least Squares (IRLS) method....
