Using a switching signal from a coarsefine switching and operation mode switching circuit, the width of change of a counter control value during power up is increased, and the width of change is reduced once a steady state is reached. By constructing, profiling, and analyzing a sequential list of functions to be executed in a parallel fashion, corresponding parallel execution templates may be stored for future lookup in a database. The upstream receiver system is configured to receive upstream wireless communications from the user over a plurality of upstream channels. The first wire has a high tensile strength and the second wire has a low tensile strength that is lower than the high tensile strength of the first wire. The mixture formation or homogenization of the gases in the reaction chamber can be improved if at least one second opening is arranged within the first row between two openings.
