a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
The effects of gating system and pattern geometry on the metal flow in the lost foam casting (LFC) process have been investigated using glass covered mold and video recording system. Unlike convectional casting process, the type of the gating system showed little effect on fillability in lost foam, but pattern thickness had large effect on mold filling. The mold filling behavior seems to be con...

In this paper, the feasibility of using heat energy of steam turbine combined cycle power plant as the energy required to start up desalination systems has been studied. The optimal model of combined cycle power plant equipped with a multi-effect desalination plants in different design modes of the effects of desalination and steam pressure of the steam turbine output has been evaluated. In ord...
