Systems and methods are disclosed herein providing an improved approach to phased array antenna communications. The present invention further relates to processes for the preparation of compounds of formula I. Mass polymerization for amorphous polymers is carried out without solvents below the glass transition temperature and for crystalline polymers below the melting point, achieving a high degree of conversion of the monomers. The control system computes a new utilization metric to be a difference between a full utilization value and the utilization slack value.
