A Polynomial Chaos Method for Dispersive Electromagnetics

Creator:: Gibson, Nathan L.
Abstract:: Electromagnetic wave propagation in complex dispersive media is governed by the time dependent Maxwell’s equations coupled to equations that describe the evolution of the induced macroscopic polarization. We consider “polydispersive” materials represented by distributions of dielectric parameters in a polarization model. The work focuses on a novel computational framework for...

Dimension reduction of decision variables for multireservoir operation: A spectral optimization model

Creator:: Chen, Duan, Leon, Arturo S., Gibson, Nathan L., and Hosseini, Parnian
Abstract:: Optimizing the operation of a multireservoir system is challenging due to the high dimension of the decision variables that lead to a large and complex search space. A spectral optimization model (SOM), which transforms the decision variables from time domain to frequency domain, is proposed to reduce the dimensionality. The...

C., Winstrup, Mai, Wong, Gifford J., and Woodruff, Thomas E.
Abstract:: The last glacial period exhibited abrupt Dansgaard–Oeschger climatic oscillations, evidence of which is preserved in a variety of Northern Hemisphere palaeoclimate archives¹. Ice cores show that Antarctica cooled during the warm phases of the Greenland Dansgaard–Oeschger cycle and vice versa[superscript 2,3], suggesting an interhemispheric redistribution of heat through a mechanism...
