originating from vygotsky’s sociocultural theory, dynamic assessment (da) proposes a novel approach to second language acquisition (sla) research according to which a dialectical relationship is envisaged between instruction and assessment. although da has been applied to some areas of sla, there are areas, such as interlanguage pragmatics (ilp), that have been neglected.  to address the issue,...

abstract one of the basic assumptions in hub covering problems is considering the covering radius as an exogenous parameter which cannot be controlled by the decision maker. practically and in many real world cases with a negligible increase in costs, to increase the covering radii, it is possible to save the costs of establishing additional hub nodes. change in problem parameters during the pl...

We demonstrate high dynamic range (HDR) imaging with the Plenoptic 2.0 camera. Multiple exposure capture is achieved with a single shot using microimages created by microlens array that has an interleaved set of different apertures. © 2009 Optical Society of America OCIS codes: (040.1490) Cameras, 110.5200 Photography.

in recent years, researchers have become interested in examining the effect of pettlep imagery on motor performance and how pettlep imagery can improve the performance. the aim of this study was to compare the effect of pettlep imagery and balance practice on dynamic balance in the elderly. participants were 42 male elderly in arak city. they were divided into 4 groups based on the scores of dy...

insulin-like growth factor (igf-1) is an anti-apoptosis factor in multiple cell types associated with various cancers. computational methods allow investigating the systems between 50–100 atoms in the frame of quantum mechanics and up to 50,000 atoms with molecular dynamics. since there are specific interactions between the residues, the solvent could play an important role in the stability of ...

this paper studies the dynamic behavior of price elasticity and its effects on the overall profit. although price elasticity has a significant effect on sales, its dynamics have not been examined so far in pricing models. in this paper, a simple pricing model is suggested in which, price elasticity is considered dynamic. the suggested pricing model is concerned with a monopolist that its object...

this paper presents dynamic portfolio model based on the merton's optimal investment-consumption model, which combines dynamic synthetic put option using risk-free and risky assets. this paper is extended version of methodological paper published by yuan yao (2012) cite{26}. because of the long history of the development of foreign financial market, with a variety of financial derivatives, the ...

planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. the problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...

the concept of imagery is to make an image of successful movement skill or a relaxing image in mind with no body training and external experience. the aim of the present study was to compare the effect of traditional and pettlep mental imagery methods on static and dynamic balance. the statistical population consisted of all female university of tehran students who had general physical educatio...
