An Investigation of Direct Hydrocarbon (Propane) Fuel Cell Performance Using Mathematical Modeling
International Journal of Electrochemistry, 2018 An improved mathematical model was used to extend polarization curves for direct propane fuel cells (DPFCs) to larger current densities than could be obtained with any of the previous models.

Polarization Evolution of Gamma-Ray Burst Prompt Emission with Bulk Acceleration
The Astrophysical JournalDuring the prompt phase, Poynting-flux-dominated jets undergo acceleration accompanied by magnetic dissipation. By using an outward-propagating thin-shell model, where bulk Lorentz factors Γ increase with radius and the magnetic field strength decay is ...

Multi-epoch Doppler tomography and polarimetry of QQ Vul [PDF]
, 1999 We present multi-epoch high-resolution spectroscopy and photoelectric polarimetry of the long-period polar (AM Herculis star) QQ Vul. The blue emission lines show several distinct components, the sharpest of which can unequivocally be assigned to the ...

Infinitesimal adjunction and polar curves [PDF]
Bulletin of the Brazilian Mathematical Society, New Series, 2009 The polar curves of foliations $\mathcal F$ having a curve $C$ of separatrices generalize the classical polar curves associated to hamiltonian foliations of $C$. As in the classical theory, the equisingularity type ${\wp}({\mathcal F})$ of a generic polar curve depends on the analytical type of ${\mathcal F}$, and hence of $C$.

Inversion of polarimetric data from eclipsing binaries [PDF]
, 1998 We describe a method for determining the limb polarization and limb darkening of stars in eclipsing binary systems, by inverting photometric and polarimetric light curves. Because of the ill-conditioning of the problem, we use the Backus-Gilbert method

Base points of polar curves [PDF]
Annales de l'Institut Fourier, 1991 The base points of the system of polar curves of an irreducible algebroid plane curve with general moduli are determined. As consequences a lower bound for the Tjurina number and many continuous analytic invariants of the curve are found.
