Analysis of Accelerograms with Recursive-Filter Method

A Three-Dimensional Variational Data Analysis Method with Recursive Filter for Doppler Radars

In this paper, a new method of dual-Doppler radar wind analysis based on a three-dimensional variational data assimilation (3DVAR) approach is proposed. In it, a cost function, including background term and radial observation term, is minimized through a limited memory, quasi-Newton conjugate-gradient algorithm with the mass continuity equation imposed as a weak constraint. In the method, the b...

Digital Filter Designs for Recursive Frequency Analysis

Digital filters for recursively computing the discrete Fourier transform (DFT) and estimating the frequency spectrum of sampled signals are examined, with an emphasis on magnitude-response and numerical stability. In this tutorial-style treatment, existing recursive techniques are reviewed, explained and compared within a coherent framework; some fresh insights are provided and new enhancements...

Analysis of MCG with spatial filter method

Magnetocardiogram (MCG) mapping is a new promising non-invasive tool for obtaining functional information concerning the electrical activities of the heart. Since MCG was first measured by Baule and McFee[1], the MCG has been studied worldwide. In particular, it is known that Cohen and his co-workers measured the MCG by use of a SQUID inside a magnetically shielded room[2] and the technique has...

Analog Modeling of Recursive Estimator Design with Filter Design Model

The low power solution for developing the application specific design methodologies using recursive coding had become central topic of modern research .In 3G mobile communication systems, in order to achieve low power consumption and high speed at low cost design. This paper focuses on implementing a design methodology using recursive encoder /decoder for optimizing the power and area and analy...
