Tri-axial Octupole Deformations and Shell Structure [PDF]
Manifestations of pronounced shell effects are discovered when adding nonaxial octupole deformations to a harmonic oscillator model. The degeneracies of the quantum spectra are in a good agreement with the corresponding main periodic orbits and winding ...

Harmonic Analysis of DFIG Wind Turbine
This proposal investigates the self-excitation of the asynchronous generator while operating in an isolated mode. With this research, we hope to improve the quality of electrical energy produced under various environmental conditions and to promote the use of renewable energies throughout rural areas in order to better support rural areas in the areas ...

Topological string in harmonic space and correlation functions in $S^3$ stringy cosmology [PDF]
We develop the harmonic space method for conifold and use it to study local complex deformations of $T^{\ast}S^{3}$ preserving manifestly $SL(2,C) $ isometry. We derive the perturbative manifestly $SL(2,C) $ invariant partition function $\mathcal{Z}_{top}
