Multi-replicA decoding using correlation baSed LocAlisAtion (MARSALA) is a recent random access method for satellite communications. It follows the multiple transmission and interference cancellation scheme of Contention Resolution Diversity Slotted Aloha (CRDSA). Besides, at the receiver side, MARSALA uses autocorrelation to localise replicas of a same packet so as to combine them. This signal...
The communication models found in distributed systems can be classified according to the following two attributes: who initiated the communication and how the communication partner is addressed. The resulting four models are shown in Table 1. Provider-initiated communication is also often called push communication and consumerinitiated communication is also often called pull communication. abst...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
Background: Empathy and emotional expression as important psychological elements play a key role in the marital satisfaction of couples. The pre-marriage counseling models are designed to increase positive coupleschr('39') communication behaviors and emotional style. Accordingly, the main purpose of this study was to compare the Effects of marriage preparation based on Satir’s communication mod...
Voltage control is one of the imperative issues in the smart distribution control system. While traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. With using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...
Introduction: Nursing recording and reporting is an important part of nursing care that can be useful and necessary for patients, nurses, and other health care providers. Objective: The purpose of this study was to compare the effect of lecture training and multimedia training on knowledge, attitude and department nurses’ emergency performance in applying a communication model in nursing recor...
Among various cultural models, the dichotomy of static versus dynamic models has provided a fertile ground for research. Although a number of static models are suggested, the dominant trend in almost all static models is provided by Hofstede who focuses on cultural differences along four major dimensions (power distance, individualism, uncertainty avoidance, and masculinity) and reduces “the co...
In this paper, Dervin’s sense-making methodology as one of the well-known theories in communication science is introduced and its implications for humanities research process is discussed. Sensemaking is the process of constructing mental framework out of encountered situations in such a way that guides behaviors and makes them meaningful. Despite the diversity of theoretical domains, existing ...
Background and Aim: Science is the result of collective thinking and sharing of findings and the use and critique in collective spaces. Also, Researchers share scientific findings by using communication platforms. Therefore, platforms play an important role in development of science. With the creation of communication and information technologies, scholarly journals have placed considerable pos...
A variety of idealized models of communication systems exist, and all may have something in common. Starting with Shannon’s communication model and ending with the OSI model, this paper presents progressively more advanced forms of modeling of communication systems by tying communication models together based on the notion of flow. The basic communication process is divided into different spher...
