Introduction This report from the Center for Competitive Analysis (CCA) of the University of Missouri is intended to provide basic background information about the Boat Building and Repairing (BBR) industry (SIC code 3732, essentially the same as NAICS code 336612, but the latter does not include boat repairing). Nationally, average 1998 weekly earnings for workers in this industry were $465.79...

The simplicity of deployment and perpetual operation energy harvesting devices provides a compelling proposition for new class edge the Internet Things. In particular, Computational Radio Frequency Identification (CRFID) are an emerging battery-free, computational, sensing enhanced that harvest all their operation. Despite wireless connectivity powering, secure firmware updates remains open cha...

A three-family non-supersymmetric model with U(3)3 gauge symmetry is analyzed in the context of intersecting D-branes. This is equivalent to the ‘trinification’ model extended by three U(1) factors which survive as global symmetries in the low energy effective model. The Standard Model fermions are accommodated in the three possible bifundamental multiplets represented by strings with endpoints...
