In Figure 2(d), the discontinuous curves sectorize the dispersion curves and delimit the highest resolution zones for the dispersion curve, identifying low energy zones (lower frequency values) and aliasing zones with several energy peaks (greater frequency values).
The Bureau of Corrections (BuCor) is also initiating moves to "sectorize" and "put a semblance of segregation" in the long-neglected New Bilibid Prison (NBP) in Muntinlupa City, said its director, Franklin Jesus Bucayu.
