Recent research projects include the development of software based analysis techniques designed to assess the elements of an inverse Jacobian matrix based upon a nonparametric specification of the Jacobian matrix. The computer programs apply mathematical results derived separately on the stability and invertibility of matrices as related to characteristics of their signed directed graphs. Applications of the results have been found in computer model quality control and the evaluation of econometric models.

and consumption of energy products through the year 2020. Solutions are
prepared under alternative assumptions concerning economic performance, the
characteristics of international markets for oil, technological change, and
government regulatory policies. Currently, NEMS is being used to assess the
economic and other impacts of reducing carbon emissions from the combustion of
fossil-based energy as agreed in
