although the history of communication is as old as history of human society, the speed and volume of communication with the advent of electronic era in the 19th century created a revolution in the communication technology. at a time when prussia was traversing the path of industrialization and the number of companies investing in different industries was increasing by the day, the company of si...

for last years, the evolution of new issues has incited a great development of the transportation system. in this paper, we discuss ingredients of its (intelligent transportation system) that are inter-vehicle communication (ivc) or what can call vehicular ad hoc networks (vanet), which are special type of manet. we will survey the main issues relevant to vanet in detail with providing a concep...

a new meta-heuristic method, based on neuronal communication (nc), is introduced in this article. the neuronal communication illustrates how data is exchanged between neurons in neural system. actually, this pattern works efficiently in the nature. the present paper shows it is the same to find the global minimum. in addition, since few numbers of neurons participate in each step of the method,...

Early warning systems are key components of strategies to reduce risk. This research, by adopting a systematic approach in the management of the risk of desertification and by including previously developed models and systems, offers an integrated efficient structure in terms of early warning for the risk of desertification as a pilot system for semi-arid areas of west Golestan Province in IRAN...

background: well-designed interventions can improve the communication skills of physicians. since the understanding of the current situation is essential for designing effective interventions, this study was performed to determine medical interns’ confidence and use of communication skills. m aterials and methods: this descriptive-analytical study was performed in spring 2013 within 3 branches ...

The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...

Global Maritime Distress Safety System (GMDSS) is one of the best and most efficient systems for emergency. The systems have been developed to provide mariners global communications and locating network. This system includes land stations for all INMARSAT services to reporting at sea, and so far using this communication system, in marine emergency situations has helped rescue thousands of lives...
