Constrained Clustering for Frequency Hopping Spread Spectrum Signal Separation
Frequency Hopping Spread Spectrum (FHSS) signaling is used across many devices operating in both regulated and unregulated bands. In either situation, if there is a malicious device operating within these bands, or more simply a user operating out of the required specifications, the identification …

Demographic Investigation of a Piscataway Creek Ossuary
Skeletal material from an ossuary on Piscataway Creek was analyzed to determine the minimum number of individuals present, and their sex, stature, developmental life stage and age at death. Cultural debris indicated a date of about 1400-1500 A.D. for the burial. At least 281 individuals were …
