fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

what is the simplest definition of ion exchange capacity

What this unit identifies for the ion exchange capacity ca. 0.92 meq. g-1. I am a newcomer in the membrane area. I just started. I highly appreciate your help

for VLC systems,channel transfer function "H"needs to be modelled.The received optical SNR is mod(H) square times degraded for the path of consideration(LOS / Diffused).

Stefano Truzzi

Yes, i know this. I model VLC with a LOS channel. My problem is different: i want a mathematics (statistics) BER calculation for an ON-OFF keying Not Return Zero demodulator.

The demodulator has an average threshold level. If the received signal is higher then average threshold the received signal is set to 1 else the received signal is set to zero.
