The present invention provides a cellular thermal neutron detector, comprising: a cellular structure comprised of one or more hollow regular hexagonal prism-shaped cellular units, wherein a neutron absorbing material is coated on an inner side of a pipe wall of each of the cellular units. Furthermore, a decoder applies a noise filling operation using a manipulated noise filling estimate depending on a harmonic or speech characteristic of the audio signal. Extracting attributes from the capture data provides a scheme to determine relevant characteristics of the hang. The emulation cycle is completed using an instruction sequencer within the interface independent of the simulator. An axially extending segmented ring with circumferential teeth is located at the top of the base. The coating can be clear or pigmented, and thus optionally can include pigment.
