Adaptive mode-suppression and disturbance-rejection scheme with application to disk drives
(2009)The goal of a track-following controller for a disk drive is to maintain as close to perfect tracking as possible. Better tracking allows for more data to be stored on a single disk. There are several factors which make ...

An AM-FM model for motion estimation in atherosclerotic plaque videos
(2007)We present new multidimensional Amplitude-Modulation Frequency-Modulation (AM-FM) methods for motion estimation. For a single AM-FM component we show that the optical flow constraint leads to separate equations for amplitude ...

Evaluation of spatial dependence matrices on multiscale instantaneous amplitude for mammogram classification
(Springer Verlag, 2015)Breast cancer is the most common cancer in women. Mammography is the only breast cancer screening method that has proven to be effective. Mammographic breast density is increasingly assessed towards the development of more ...

On the use of high frequency measures of volatility in MIDAS regressions
(2016)Many empirical studies link mixed data frequency variables such as low frequency macroeconomic or financial variables with high frequency financial indicators’ volatilities, especially within a predictive regression model ...

Regression models with mixed sampling frequencies
(2010)We study regression models that involve data sampled at different frequencies. We derive the asymptotic properties of the NLS estimators of such regression models and compare them with the LS estimators of a traditional ...

Robust estimation with applications to phase and envelope estimation in frequency selective wireless fading channels
(2008)This paper derives robust niiniinax estimators for a class of uncertain models. The uncertainty is described by a relative entropy constraint between the unknown joint distribution and a fixed nominal joint distribution. ...

Spectral density and spectral distribution inference for long memory time series via fixed-b asymptotics
(2014)This paper studies taper-based estimates of the spectral density utilizing a fixed bandwidth ratio asymptotic framework, and makes several theoretical contributions: (i) we treat multiple frequencies jointly, (ii) we allow ...
