DFTS on Irregular Grids: The Anterpolated DFT
Abstract : In many instances the discrete Fourier transform (DFT) is desired for a data set that occurs on an irregular grid. Commonly the data are interpolated to a regular grid, and a fast Fourier transform (FFT) is then applied. A drawback to this approach is that typically the data have unknown smoothness properties, so that the error in the ...

Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Physical properties of ternary chloro-perovskites KTCl3 (T = Ge, Al) for optoelectronic applications
This study uses density functional theory to investigate various properties of ternary chloro-perovskites, KTCl3 (T = Ge or Al). Both compounds have a cubic structure with lattice parameters of 5.159 Å for KAlCl3 and 5.378 Å for KGeCl3.

Hermitian Symmetric DFT Codes: A New Class of Complex DFT Codes
We introduce a new class of real number codes derived from DFT matrix, Hermitian symmetric DFT (HSDFT) codes. We propose a new decoding algorithm based on coding-theoretic as well as subspace based approach. Decoding of HSDFT codes requires only real arithmetic operations and smaller dimension matrices compared to the decoding of the state-of-art real ...
