Mitigating timing noise in ADCs through digital post-processing
… on the Gibbs sampler that all approach the Bayes least squares estimate are designed. These estimators are compared in performance to the optimal linear estimators derived without taking jitter into account.

Robust mixtures of regression models
… assume a normal distribution for error and then estimate the regression param- eters by the maximum likelihood estimate (MLE). In this project, we demonstrate that the MLE, like the least squares estimate, is sensitive to outliers and heavy-tailed error distributions. We propose a robust …

Optimal parameter adaptive estimation of stochastic processes
… is concerned with the simultaneous detection and least squares estimation of vector random processes. The problem is formulated in the following context: A random process, out of a countably infinite collection of (not necessarily Gaussian) vector random processes with known distributions, is …

Velocity and Q from reflection seismic data
… velocity at Nyquist. From (1) it is possible to estimate Q in the time domain by measuring the amount of increase, ΔW, of the wavelet breadth after a traveltime, Q=(2Δ𝛕)/(𝝅ΔW) The inverse problem, i.e., the determination of Q and velocity is also investigated using singular value decomposition …

OnBoard Parameter Identification for a Small UAV
… Newton-Raphson minimization with starting values estimated from a Least-Squares Estimate of the non-dimensional stability and control derivatives. For the frequency domain approach, both the states and inputs were first converted to the frequency domain using a Fourier integral over the frequency …

Time Delay Estimate Based Direction of Arrival Estimation for Speech in Reverberant Environments
… (TIDES) based on either minimizing the weighted least squares error (MWLSE) or minimizing the time delay separation (MWTDS). In the TIDES algorithm, we consider not only the maximum likelihood (ML) TDEs for each pair of microphones, but also other secondary delays corresponding to smaller peaks …
