â â â  â  â â â â â â â  abstract â  the abtalkh formation in the kopeh-dagh basin in northeastern iran with an age of late cretaceous (turonian – santonian) is selected to evaluate resolution of magnetic susceptibility for assessing sea level fluctuations. thirty-nine shale samples were collected and studied for magnetic susceptibility and palynology. assuming the average ms magnitude as the...

The self-organizing map is an algorithm which can be used to establish the presence of various categories in a given numerical and non-numerical data and to visualize the complex topographical relations between the various such categories in a low dimensional and easily comprehensible display. In this paper, SOM has been used to visualize the output of a wireless channel in the presence of inte...

This paper applies irreversibility analysis to characterize humidification-dehumidification (HD) desalination cycles and to identify how to further improve cycles and components. It is shown that minimizing specific entropy generation of the cycle maximizes the gained output ratio (GOR). It is also shown that each cycle has one limiting component that cannot be substantially improved and a seco...

The wireless communications channel is commonly modelled as imposing a Rayleigh distributed envelope onto any incumbent signals. Antenna arrays have long been recognised as enabling exploitation of signal spatial diversity in such an environment based upon the assumption of uncorrelated signals at the different antennas. However, it is precisely the relative positions of the antennas which dete...
