The physical connection corresponding to IP tunnels in a network are found by tracing through the device configuration and routing tables at the routers in the network to determine the outbound interface associated with each tunnel endpoint, and then inferring a likely return interface associated with the opposite tunnel endpoint. More particularly, ballistic resistant fibrous composites having enhanced a dynamic storage modulus, which correlates to low composite backface signature. A sensor fusion module 108 may be included to produce a unified estimate of the user’s angular rotation rate and current orientation to be provided to an orientation and rate estimate module 120. The web sites send messages to the relationship server that reference the end-users using the identifiers and describe the relationships observed for the end-users. The valve body is shaped to have a projection, thereby allowing an airflow formed by the intake flow control valve to bypass the projection within the intake pipe located downstream of the intake flow control valve. The multidimensional system is robust and performs predictive data analysis well even when there are incidences of multi-collinearity and variables with zero standard deviations in reference group or unit space.
