zika virus is an arbovirus identified first time in 1947 in uganda. zika epidemic is a threat far greater than the ebola outbreak. the world health organization has urged asian countries to be vigilant about the risk of spreading zika virus and preventive measures to control it. in iran, 64 species of mosquitoes from culicidea family have been reported three of which belong to the aedes genus, ...

With the continuously expanding scale of the electric power grid in recent years, wildfire has been one of the main disasters which threaten the security of operation of power grid. Therefore, accurate, reliable, professional wildfire rating and forecasting along transmission lines has become a big challenge for entrepreneurs in power grid. In this paper, the combination of factors in power gri...

Computer aided design and computer aided modeling tools are becoming increasingly important in the design and performance evaluation of communication systems. In this work, we report on the computer simulation modeling study of terrestrial digital microwave radio transmission, using Block Oriented System Simulator package (BOSS). The work concentrates on semi-analytical error rate evaluation in...

abstract due to transmission losses and lack of initial flow, flood routing in ephemeral streams is not possible with common methods and it is necessary the flood routing models have been developed for these streams. therefore in this study a computer model for natural river cross section has been developed in that after linearization of partial differential equations of unsteady none uniform f...

Transmission loss and noise reduction of reactive mufflers are determined by linear acoustic theory and unsteady flow field study, respectively. The effects of extending the inlet tube of the muffler, adding holes to the extension, and the number of holes on both transmission loss and noise reduction are investigated. In noise reduction analysis, the Navier-Stokes equations and k-ε model are us...

There is a great resolution calling for smart grids in recent years. Introduction of new technologies, that make the network flexible and controllable, is a main part of smart grid concept and a key factor to its success. Transmission network as a part of system network has drawn less attention. Transmission switching as a transmission service can release us from load shedding and remove the co...
