This is a preview. Log in through your library . Abstract The Time Variant Discrete Fourier Transform was implemented as a real-time order tracking method using developed software and commercially ...

This paper presents an efficient methodology for discrete Asian options that is consistent with different types of underlying densities – especially non-normal returns as suggested in the empirical ...

Sparse Fourier Transform (SFT) algorithms constitute a transformative approach to spectral analysis by leveraging the inherent sparsity of signals in the frequency domain. In contrast to the ...

In this project, we rebuild the theory of economic agglomeration in the context of many-location geography. Depending on the spatial scale of the region in question, we utilize appropriate techniques, ...
