Query: Numerical study on the effect of design parameters and spacers on RPC
  signal and timing properties   Numerical calculations have been performed to understand the reason for the
observed non-uniform response of a Resistive Plate Chamber (RPC) in a few
critical regions such as near edge spacers and corners of the device. In this
context, the signal from a RPC due to the passage of muons through different
regions has been computed. Also, a simulation of RPC timing properties is
presented along with the effect of the applied field, gas mixture and
geometrical components.
