Complex energy modeling is increasingly central to the development of electricity sector regulations, and perhaps increasingly necessary. But environmental agencies need to remain vigilant to avoid vulnerabilities created when models designed for broad energy system projections are repurposed for the design of detailed pollution control policies. All models are false, some are useful, and by im...

We investigate both numerically and experimentally soliton propagation in a fiber loop with dispersion management, in-line filters, and frequency shifting. More than 90% of the fiber in the loop is in the normal-dispersion regime, but the net dispersion is anomalous. Stable pulses in the loop have an enhanced power relative to solitons in a fiber with uniform dispersion equal to the loop's path...

The thesis deals with the modeling of air pollution transportation and dispersion processes in the atmosphere, more precisely with the numerical approaches to solve such models. The modeling of air pollution has a great importance for prediction of the contaminations and it helps with understanding of the process and with elimination of its consequences. The models which are described by partia...
