Query: Friedmann-Robertson-Walker Braneworlds   We study the cosmological evolution with nonsingular branes generated by a
bulk scalar field coupled to gravity. The specific setup investigated leads to
branes with a time-dependent warp factor. We calculate the effective Hubble
parameter and the effective scale factor for the FRW branes obtained solutions.
The spatially dependent branes solutions also were found.
