Abstract: A method for computing a fast Fourier transform (FFT) in a parallel processing structure uses an interleaved computation process. In particular, the interleaved FFT computation process intertwines the output of two different shifted Fourier matrices to obtain a Fourier transform of an input vector. Next, an even-odd extension process is applied to the transformed input vector, whereupon various terms are grouped in a computational tree. As such, the resulting segmentation of the computation allows the fast Fourier transform to be computed in a parallel manner.

Abstract: The invention provides a system of devices and a set of methods for accurately characterizing, tracking and controlling bulk material flows. Measurements of input material properties, dynamical measurements involving identifiable tags, and fast, discrete simulations are combined to predict and control the composition of bulk material exiting a container, such as a silo, bunker or hopper. In one embodiment, a system is provided for a coal-fired power plant where the properties of coal are assessed, then the coal is marked and tracked to provide the plant's operators improved control over the coal mixture and target bulk properties as it makes its way from a coal receiving station to delivery for combustion in a furnace.
