In one embodiment, the invention is a method. The system includes a planner to determine different plans for addressing a problem, and a graphics engine for displaying the process model for the different plans. Upon curing the sealant, a substantially gas impermeable graphite plate is provides. The heat shield includes a first section supported by the support and having a decreased thermal conductivity and a second section abutting the first section in an axial direction of the heat shield and having an increased thermal conductivity greater than the decreased thermal conductivity of the first section. The client device then renders a second media stream at a position corresponding to the real-time offset to be in synchrony to the media stream being rendered by the media rendering source.
