Abstract Following the advances in mobile communication and information technology, smart phones have been used in a wide variety of commercial, social, entertainment, file sharing and health transactions and applications. The current procedures in healthcare environment for patient registration, appointment scheduling and payment are time consuming and somehow tiresome. Traditionally, patie...

Communication and transportation networks are among the most important infrastructures critically involved in the development of different countries. The structural and tectonic position of Iran causes significant damage to its communication networks every year. Therefore, it is essential to adopt an integrated and flexible approach for assessing seismic risk in terms of available indicators. T...

Abstract Power line communication technology is a retrofit alternative for last mile information technology. Despite several challenges, such as inadequate standards and electromagnetic compatibility, it maturing. In this review, we have analysed these obstacles its current application status.

The fiber-optic communication lines and transmission systems using cable, receiving transmitting optical modules based on WDM DWDM (Wavelength Division Multiplexing & Dense WDM) technologies are studied. A method for calculating the characteristics is proposed relationships obtained that establish an analytical relationship between length regeneration section rate. This paper discusses stud...

This paper presents the design of a power line communication model. Primarily, it is focused on a realization of a communication model with a power line channel. The model is composed of a PLC communication model, a model of power lines and a noise model. Power lines are modelled through a chain parameter describing the relation between the input and output voltage and current of the two-port n...

Junctional intercellular communication between several established human breast cancer cell lines and a variety of mammalian cells has been examined. All the cancer cell lines were found to be either noncommunicators or nonselective communicators. This contrasts with normal human mammary epithelium which shows selectivity in junctional communication. Loss of selectivity in junctional communicat...
