Any language classroom is a distinctive learning context offering numerous affordances that might be perceived effectively, remain unnoticed, or even act as constraints. Therefore, exploring students' perception toward a particular method of instruction is crucial since it may produce a reliable piece of evidence for teachers to confirm or refute the effectiveness of the intended instructional ...

We consider a problem of managing a system of spatially distributed markets under capacity and balance constraints and show that solutions of a variational inequality enjoy auction principle properties implicitly. This enables us to develop efficient tools both for derivation of existence and uniqueness results and for creation of solution methods.

the distribution of the allophones of /?/in certain contexts involves free variation and gradient preferences. an organized survey was conducted to elicit the judgments of 37 native persian speakers concerning the well-formedness of /?/allophonic behavior in five different phonological positions. the results showed that the differences in judgment between the various categories are not just t...

Segmentation of femurs in Anterior-Posterior x-ray images is very important for fracture detection, computer-aided surgery and surgical planning. Existing methods do not perform well in segmenting bones in x-ray images due to the presence of large amount of spurious edges. This paper presents an atlas-based approach for automatic segmentation of femurs in x-ray images. A robust global alignment...

Abstract If there is some truth to the adage that justice must not only be done, but seen then surely it done in a timely manner. Yet court congestion and delays – which threaten undermine system have become global phenomena with significant adverse implications for social welfare, economic development, civil rights.

This article is a brief exposure of the process approach to a newly emerging area called "discrete event systems" in control theory and summarizes some of the recent developments in this area. Discrete event systems is an area of research that is developing within the interstices of computer, control and communication sciences. The basic direction of research addresses issues in the analysis an...
