Cramer-Rao Bounds for Road Profile Estimation
(IEEE, 2017)In this paper, we study estimator accuracy in road profile identification. We derive a Cramer-Rao lower bound on the variances of all unbiased waviness parameter estimators for an ISO 8608 road profile, widely used in ... -
Power spectrum estimation with missing values
(IEEE, 2015)In this paper, we consider estimation of a power spectrum from noise corrupted spectrum samples on uniform grids of frequencies with missing values. A scheme based on regularized nuclear norm optimization and subspace ... -
Parallel Track Models from Road Measurements
(IEEE, 2017)In this paper, coherence function estimation for parallel tracks from road measurements is studied. A two-stage scheme is proposed. In the first stage, the measurements are de-trended and periodic components are removed. ... -
Regularized Nuclear Norm Spectrum Estimation in Frequency Domain
(IEEE, 2013)Subspace-based methods have been effectively used to estimate multi-input/multi-output, discrete-time, linear-time invariant systems from spectrum samples. A critical step in these methods is the splitting of causal and ... -
Subspace-based rational interpolation of analytic functions from real or imaginary parts of frequency-response data
(IEEE, 2009)In this paper, construction of analytic functions from evaluations of real or imaginary parts on finite subsets of the unit circle is studied. The points in the subsets are not necessarily uniformly spaced as in the most ... -
Identification of acoustic spectra for fault detection in induction motors
(IEEE, 2013)In this paper, we study fault detection problem for induction motors by using a recently developed cross-power spectral density estimation algorithm from sound measurements. In a test rig, from multiple experiments the ... -
Identification of power spectra by reweighted and regularized nuclear norm minimization
(IEEE, 2015)In this paper, we study model order choice in subspace identification algorithms using uniformly spaced spectrum measurements. In these algorithms, model order is determined by singular-value decomposition of a structured ... -
Subspace-Based Spectrum Estimation By Nuclear Norm Minimization
(IEEE, 2013)Subspace-based methods have been effectively used to estimate multi-input/multi-output, linear-time-invariant systems from noisy spectrum samples. In these methods, a critical step is splitting of two invariant subspaces ... -
A spectral estimation case study in frequency-domain by subspace methods
(IEEE, 2013)In this paper, the properties of two recently proposed frequency-domain subspace-based algorithms to estimate discrete-time cross-power spectral density (cross-PSD) and auto-power spectral density (auto-PSD) matrices of ... -
Time-domain identification of rational spectra with missing data
(IEEE, 2016)In this paper, we study modelling of rational spectra from time-domain measurements when the measurement information is not complete. We propose a three-stage estimation scheme. In the first-stage, rational spectra are ... -
Wind Speed Forecasting with Missing Values
(IEEE, 2017)In this study, a new short term wind speed forecasting approach, which uses long term past observations, is proposed. The performance assessment of the wind speed forecasting framework is carried out using real data from ... -
Short-Term Wind Speed Forecasting by Spectral Analysis
(IEEE, 2018)In this paper, we apply a wind speed forecasting framework developed earlier by the authors to the two-dimensional wind velocity measurements collected from a meteorological station in the Marmara region of Turkey over a ... -
An Adaptive Algorithm for Detection of Multiple-Type, Positively Stained Nuclei in IHC images with minimal Prior Information: Application to OLIG2 Staining Gliomas
(Spie-Int Soc Optical Engineering, 2015)We propose a method to detect and segment the oligodendrocytes and gliomas in OLIG2 immunoperoxidase stained tissue sections. Segmentation of cell nuclei is essential for automatic, fast, accurate and consistent analysis ... -
RMS Performance Limitations and Constraints for Quarter-Car Active Suspensions
(IEEE, 2008)In this paper, performance limitations and constraints for an actively controlled quarter-car model subject to white or colored-noise velocity road inputs are investigated. It is demonstrated that tire damping by coupling ... -
Automated detection of cells from immunohistochemically-stained tissues: Application to Ki-67 nuclei staining
(Spie-Int Soc Optical Engineering, 2012)An automated cell nuclei detection algorithm is described to be used for the quantification of immunohistochemically-stained tissues. Detection and segmentation of positively stained cells and their separation from the ...
