CMB temperature and polarization pseudo-Cl estimators and covariances
We develop the pseudo-Cl method for reconstructing the Cosmic Microwave Background (CMB) temperature and polarization autoand cross-power spectra, and estimate the pseudoCl covariance matrix for a realistic experiment on the cut sky. We calculate the full coupling equations for all six possible CMB power spectra, relating the observed pseudo-Cl’s to the underlying all-sky Cl’s, and test the rec...
متن کاملA Variable Structure Observer Based Control Design for a Class of Large scale MIMO Nonlinear Systems
This paper fully discusses how to design an observer based decentralized fuzzy adaptive controller for a class of large scale multivariable non-canonical nonlinear systems with unknown functions of subsystems’ states. On-line tuning mechanisms to adjust both the parameters of the direct adaptive controller and observer that guarantee the ultimately boundedness of both the tracking error and tha...
متن کاملLarge Scale Experiments Data Analysis for Estimation of Hydrodynamic Force Coefficients
This paper describes the various frequency domain methods which may be used to analyze experiments data on the force experienced by a circular cylinder in wave and current to estimate drag and inertia coefficients for use in Morison’s equation. An additional approach, system identification techniques (SIT) is also introduced. A set of data obtained from experiments on heavily roughened circular...
متن کاملLarge Scale Experiments Data Analysis for Estimation of Hydrodynamic Force Coefficients Part 1: Time Domain Analysis
This paper describes various time-domain methods useful for analyzing the experimental data obtained from a circular cylinder force in terms of both wave and current for estimation of the drag and inertia coefficients applicable to the Morison’s equation. An additional approach, weighted least squares method is also introduced. A set of data obtained from experiments on heavily roughened circul...
متن کاملMining Massive Earth Science Data Sets for Large Scale Structure
Abstract—The traditional way to look for large scale structure in very large observational or model generated data sets is to examine maps of means and standard deviations of parameters of interest on a coarse spatio-temporal grid. This approach is popular because it is easy to implement and understand, but unfortunately it throws away almost all of the distributional information in the data. M...
