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...

This paper reviews both theoretical and empirical studies of financial transmission rights (FTRs) in the major U.S. wholesale power markets and provides a simple illustrative two-stage model to study the competitive behaviors of electricity generators (wholesale power sellers) and load serving entities (LSEs)(wholesale power buyers) and the welfare effects of FTRs in the restructuring U.S. whol...

Breweries in the United States spend annually over $200 Million on energy. Energy consumption is equal to 3 – 8% of the production costs of beer, making energy efficiency improvement an important way to reduce costs, especially in times of high energy price volatility. After a summary of the beer making process and energy use, we examine energy efficiency opportunities available for breweries. ...
