Second language  learners often develop grammatical competence in the absence of concomitant pragmatic competence (Kasper & Roever, 2005) and the exact nature of the relationship between the two competences is still indistinct and in need of inquiries ( Bardovi-Harlig, 1999; Khatib & Ahmadisafa, 2011). This study is a partial attempt to address the lacuna and aims to see if any relationship ca...

Drawing upon sociocultural theory of Vygotsky, the current study aims to investigate the effect of dyadic interaction in mixed and matched level proficiency pairings on comprehension and production of request and apology speech acts. The participants were 125 EFL learners who were randomly assigned to control and experimental (interaction) groups. Based on their scores in the pretest including ...

In this paper we evaluate the effectiveness of two likelihood normalization techniques, the Background Model Set (BMS) and the Universal Background Model (UBM), for improving performance and robustness of four face authentication systems utilizing a Gaussian Mixture Model (GMM) classifier. The systems differ in the feature extraction method used: eigenfaces (PCA), 2-D DCT, 2-D Gabor wavelets an...

In modern communication technologies, the demand of image data compression increasing rapidly. This paper presents different methods for image compression like DCT, Walsh, Hadamard and Walsh Hadamard. Main objective of this paper is to achieve the higher compression ratio and lower the Mean square error. Different test images over different orthogonal transform are used to achieve the performan...

In example (1), a sentence from a Wall Street Journal article taken from the Penn TreeBank corpus is further segmented into four EDUs, (1a), (1b), (1c) and (1d) (RST, 2002). Discourse segmentation, clearly, is not as easy as sentence boundary detection. The lack of consensus with regards to what constitutes an elementary discourse unit adds to the difficulty. Building a rule based discourse seg...
