Diierential-geometric methods can and have been successfully used in control theory, not only to pose and solve new problems, but also to get new insights and prove new results about classical problems of optimal control. In particular, they yield new results on local controllability, continuity properties of value functions, the structure of reachable sets, and the properties of optimal trajec...

Two main features of vocabulary knowledge, namely breadth and depth, have a fundamental role in vocabulary research. This research aimed to study the relationship between vocabulary knowledge and reading comprehension, and to investigate which feature of vocabulary knowledge, breadth or depth, had better impact on identifying reading comprehension performance. Therefore, three language tests we...

Basic role based access control [RBAC] provides a mechanism for segregating access privileges based upon users' hierarchical roles within an organization. This model doesn't scale well when there is tight integration of multiple hierarchies. In a case where there is joint-tenancy and a requirement for different levels of disclosure based upon a user's hierarchy, or in our case, organization or ...

Abstract Acquiring vocabulary, as a significant and challenging part of language learning process, has always been consistent with reading. In this study, the researchers examined the effect of enhanced extensive reading on EFL learners’ incidental acquisition of English vocabulary, with specific focus on phrasal verbs. Twenty five homogenized participants were selected and divided into two gro...

This research explores emotional response to gesture in order to inform future product interaction design. After describing the emergence and likely role of full-body interfaces with devices and systems, the importance of emotional reaction to the necessary movements and gestures is outlined. A gestural vocabulary for the control of a web page is then presented, along with a semantic differenti...

This study used keyword method during encoding information in transferring information from short term memory to make the retrieval easier. For this purpose, 50 adult female elementary students were chosen to participate in this study. This study required two groups of learners (control and experimental groups). The experimental group enjoyed some special flashcards which each of them involved ...

The Impact of Language Learning Activities on the Spoken Language Development of 5-6-Year-Old Children in Private Preschool Centers of Langroud N. Bagheri, M.A. E. Abbasi, Ph.D. M. GeramiPour, Ph.D. The present study was conducted to investigate the impact of language learning activities on development of spoken language in 5-6-year-old children at private preschool center...

A reference model architecture for real-time hierarchical control systems has been proposed by researchers at the National Institute of Standards and Technology, and has been implemented on a variety of computing platforms for manufacturing and vehicle control applications. A fundamental aspect of this architecture is the notion of nested control loops, which incorporate sensory feedback in a h...
