    A Generalized Cauchy Distribution Framework for Problems Requiring Robust Behavior

    Statistical modeling is at the heart of many engineering problems. The importance of statistical modeling emanates not only from the desire to accurately characterize stochastic events, but also from the fact ...

    Adaptive Wavelet Transform Method to Identify Cracks in Gears

    Many damages and faults can cause problems in gear unit operation. A crack in the tooth root is probably the least desirable among them. It often leads to failure of gear unit operation. By monitoring vibratio...

    Channel Characterization and Robust Tracking for Diversity Reception over Time-Variant Off-Body Wireless Communication Channels

    In the 2.45 GHz band, indoor wireless off-body data communication by a moving person can be problematic due to time-variant signal fading and the consequent variation in channel parameters. Off-body communicat...

    Image Variational Denoising Using Gradient Fidelity on Curvelet Shrinkage

    A new variational image model is presented for image restoration using a combination of the curvelet shrinkage method and the total variation (TV) functional. In order to suppress the staircasing effect and cu...

    Two-Stage Outlier Elimination for Robust Curve and Surface Fitting

    An outlier elimination algorithm for curve/surface fitting is proposed. This two-stage hybrid algorithm employs a proximity-based outlier detection algorithm, followed by a model-based one. First, a proximity ...

    An Overview of the Adaptive Robust DFT

    This paper overviews basic principles and applications of the robust DFT (RDFT) approach, which is used for robust processing of frequency-modulated (FM) signals embedded in non-Gaussian heavy-tailed noise. In...

    Data Fusion for Improved Respiration Rate Estimation

    We present an application of a modified Kalman-Filter (KF) framework for data fusion to the estimation of respiratory rate from multiple physiological sources which is robust to background noise. A novel index...

    Impulse Noise Filtering Using Robust Pixel-Wise S-Estimate of Variance

    A novel method for impulse noise suppression in images, based on the pixel-wise S-estimator, is introduced. The S-estimator is an alternative for the well-known robust estimate of variance MAD, which does not ...
