According to one embodiment, an electronic apparatus receives a first packet group of a stream of content data. A flexible fin extends along the length of the sill and projects upwardly therefrom to form a water dam. Scintillations that occur in the flowing gas due to eddies and particulates in the gas are detected in the photodetectors at slightly different times. In another embodiment, a process control application of a programmable process controller dynamically configures its structure and memory allocation usage. The lossy matching circuits and eliminating resonator circuit are designed to make the RF amplifier unconditional stable. The constraints can include that the transform has a scaled integer implementation, provides perfect or near perfect reconstruction, has a DCT-like basis, is limited to coefficient within a range for representation in n-bits, has basis functions that are close in norm, and provides sufficient headroom for overflow of the range.
