With the increasingly obvious trend of satellite communication and network integration, especially emergence inter links, interconnection between space nodes has become development inevitable requirement future communication. However, problems, such as long distance, large transmission delay loss, limited resources frequent switching limit ability spatial information transmission. Firstly, base...

this study investigates the relationship between extraversion/introversion personality dimension and the use of strategic competence (sc) in oral referential communication by iranian efl learners. referential communication refers to a kind of guided communication in which the referents (or topics) are given to the speakers to convey their meanings to the listeners. 50 sophomore english students...

this paper showed the results of a qualitative investigation that looked into intracultural communication between brazilian teachers and students of english, and intercultural communication between american teachers and brazilian students of english. the aims were to identify and describe contextualization cues used by both brazilian and american speakers of english, and to connect these cues w...

let r be a commutative noetherian ring. we study the behavior of injectiveand at dimension of r-modules under the functors homr(-,-) and -×r-.

In this paper we formulate the problem of routing over dynamic networks with finite doubling dimension. This is motivated by communication in mobile wireless networks, where the communication graph topology changes over time, but has some geometric properties, motivating the model for finite doubling dimension. Since wireless network bandwidth is precious, we consider communication cost require...

This work studies the maximum possible sign rank of sign (N ×N)-matrices with a given Vapnik-Chervonenkis dimension d. For d = 1, this maximum is three. For d = 2, this maximum is Θ̃(N). For d > 2, similar but slightly less accurate statements hold. The lower bounds improve on previous ones by Ben-David et al., and the upper bounds are novel. The lower bounds are obtained by probabilistic constr...
