The Chow-Willsky scheme is a design method for residual generation. Here an extension to the Chow-Willsky scheme, called the ULPE scheme, is presented. The ULPE scheme is shown to be able to generate all possible residual generators for both discrete and continuous linear systems. It is also shown that previous extensions to the Chow-Willsky scheme do not have this capability. Two new straightf...

An unresolved issue in patients with diastolic dysfunction is that the estimation of myocardial stiffness cannot be decoupled from diastolic residual active tension (AT) because of the impaired ventricular relaxation during diastole. To address this problem, this paper presents a method for estimating diastolic mechanical parameters of the left ventricle (LV) from cine and tagged MRI measuremen...

This paper is concerned with the theoretical properties of high contrast coronagraphic images in the context of exoplanet searches. We derive and analyze the statistical properties of the residual starlight in coronagraphic images, and describe the effect of a coronagraph on the speckle and photon noise. Current observations with coronagraphic instruments have shown that the main limitations to...

The convergence properties of the new Regularized Euclidean Residual method for solving general nonlinear least-squares and nonlinear equations problems are investigated. This method, derived from a proposal by Nesterov (2007), uses a model of the objective function consisting of the unsquared Euclidean linearized residual regularized by a quadratic term. At variance with previous analysis, its...

Effects of laser shock processing (LSP) on the cavitation erosion resistance of laser weldments were investigated by optical microscope (OM), scanning electron microscope (SEM) observations, roughness tester, micro hardness tester, and X-ray diffraction (XRD) technology. The morphological microstructures were characterized. Cumulative mass loss, incubation period, erosion rate, and damaged surf...

According to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. The low value residual gold ions existed in acid leaching tail solution in Mouteh gold mine in Iran with fellow heavy metals as pollutants (Fe2+, Cu2+, and Zn2+). Preparation of nano gold particles is achieved by two steps: First, by addition of ammonia as separatio...

For mechanical system structural health monitoring, a new residual generation method is proposed in this paper, inspired by recent result on subspace identification. It improves statistical properties of the existing residual, which has been naturally derived from standard identification method. Replacing monitored state-space model Kalman filter one-step ahead predictor key element improvement...

The relationship between structural and low-temperature transport properties is explored for InxAl1-xAs/InxGa1-xAs metamorphic quantum wells with x > 0.7 grown on GaAs by molecular beamepitaxy. Different step-graded buffer layers are used to gradually adapt the in-plane latticeparameter from the GaAs towards the InGaAs value. We show that using buffer layers with asuitable maxim...

In the first half of the paper I study spurious regressions in panel data. Asymptotic properties of the least-squares dummy variable (LSDV) estimator and other conventional statistics are examined. The asymptotics of LSDV estimator are different from those of the spurious regression in the pure time-series. This has an important consequence for residual-based cointegration tests in panel data, ...
