There is provided self piercing rivet comprising a substantially planar metal body portion having deformable tabs symmetrically disposed about a slit as per the first embodiment. The process and system ensure that the resulting project WBS and work flow is composed of the minimum set of activities required to produce the set of outcomes desired for the project. Wherein, the digital FH transmitter performs DSP on a digital BB transmission signal to frequency-hop between BB sub-bands corresponding to sub-bands of a channel, converts it into an analog signal, and then modulates the analog signal to the channel sub-bands for transmission. A parameterizable model, called Flexible Pools, is proposed. The rear driving force is transmitted to rear wheels through a rear drive shaft and a rear differential.
