FIFO communication is expensive to support. It is also quite restrictive for several applications. In this paper, we study the concept of relative speed of messages and a hierarchy of such speeds which results in a hierarchical channel . In hierarchical channels messages sent at lower levels of the hierarchy cannot be overtaken by message sent at a higher level. But lower level messages can ove...

the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...
می توان گفت واقعیت چند لایه ا ی کلاس های زبان انگلیسی بسیار حائز اهمیت است، زیرا عواطف و بینش های زبان آموزان تحت تاثیر قرار می گیرد. در پژوهش پیش رو، گفته می شود که دبیران با در پیش گرفتن رویکرد فرا-انسانگرایی ، قادرند در زندگی دانش آموزانشان نقش مهمی را ایفا سازند. بر اساس گفته ی ویلیامز و بردن (2000)، برای کرل راجرز، یکی از بنیان گذاران رویکرد انسانگرایی ، یادگیری بر مبنای تجربه، نوعی از یاد...
The purpose of this research was to assess the role of educational factors in protecting urbanlandscapes in Tehran Metropolitan. This is a quantitative research, applied and descriptivecorrelationmethod was used. The research population consisted of all participants in educationalcourses held by Tehran municipality (N=300) and 172 of them selected by using simple randomsampling method. To gathe...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
A fundamental problem in any communication system is: given a communication channel between a transmitter and a receiver, how many “independent” signals can be exchanged between them? Arbitrary communication channels that can be described by linear compact channel operators mapping between normed spaces are examined in this paper. The (well-known) notions of degrees of freedom at level ǫ and es...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
The purpose of this research was to analyzing the perception and technical knowledge of wheat farmers in shoushtar township, Khouzestan province, Iran regarding organic farming products. The research method employed was correlative-descriptive. The population consisted of wheat farmers in Shoushtar township Khuzestan Province of Iran. A random sample of wheat farmers (n = 163) was selected. The...
All communication channels are at bottom quantum mechanical. Quantum mechanics contributes both obstacles to communication in the form of noise, and opportunities in the use of intrinsically quantum representations for information. This paper investigates the trade-off between power and communication rate for coupled quantum channels. By exploiting quantum correlations such as entanglement, cou...
