Cramer-Rao bound analysis of multi-frame blind deconvolution
… blurred and noisy images is considered. Cramer-Rao Bound theory is employed to provide an algorithm-independent metric to analyze the effects from these parameters. The Cramer-Rao bound is a lower limit to the variance of any estimate of an unknown parameter. In this research, the unknown …

Development and Resolution of Pulmonary Arterial Hypertension in RAO Horses
Equine recurrent airway obstruction (RAO) is associated with airway inflammation and bronchoconstriction in clinically affected horses. Horses demonstrating severe pulmonary compromise develop concurrent secondary pulmonary hypertension. The development of pulmonary hypertension is well documented …

Their throats were constricted: nationalism, history, and memorials in Nana Rao Park
In the north Indian state of Uttar Pradesh, Nana Rao Park in Kanpur is a microcosm for the history of India since 1857. The park exists as a space to be used for recreation, but it also houses a group of memorials that work to reinforce certain narratives. Today, the memorials tell the story of the …

Conditional Posterior Cramer-Rao Lower Bound and Distributed Target Tracking in Sensor Networks
… in the presence of noise. Posterior Cramer-Rao lower bound (PCRLB) sets a performance limit onany Bayesian estimator for the given dynamical system. The PCRLBdoes not fully utilize the existing measurement information to give anindication of the mean squared error (MSE) of the estimator in …

Cramer-Rao Lower Bound Derivation and Performance Analysis for Space-Based SAR SMTI
This thesis develops the Cram ́er-Rao Lower Bound (CRLB) for multi-channel space- borne synthetic aperture radar (SAR) system and provides surface moving target in- dication (SMTI) performance analysis. A multi-channel moving target signal model is derived in satellite earth-fixed earth-centered …

Recovering sample diversity in Rao-Blackwellized particle filters for simultaneous localization and mapping
… impoverishment, a well-known failure mode of the Rao-Blackwellized particle filter (RBPF) in simultaneous localization and mapping (SLAMI) situations that arises when precise feature measurements yield a limited perceptual distribution relative to a motion-based proposal distribution. One set of …

Response of Peripheral Blood Lymphocytes from RAO-affected Horses to b2-Agonist Stimulation
Recurrent airway obstruction (RAO) affects middle-age horses, inducing bronchoconstriction and airway inflammation. β2-agonists like salbutamol are used as treatment, promoting airway smooth muscle (ASM) relaxation and bronchodilation. In addition to ASM, inflammatory cells express the …

Relationship between surfactant alterations and severity of disease in horses with recurrent airway obstruction (RAO)
… second study was that surfactant alterations in RAO-affected horses are related to clinical stage of RAO. The objectives were 1) to compare surfactant phospholipid composition and function between Non-RAO and RAO horses at clinical stages and 2) to investigate relationships between surfactant …

Inferences on the shape parameter of the gamma distribution and Cramer-Rao lower bounds from censored data
… The second article concerns the Cramér-Rao lower bounds for the variances of estimators, where the estimators are based on censored data. Convenient techniques are derived to evaluate the lower bounds in the presence or absence of nuisance parameters"--Abstract, page iii.</p>

Biomarkers of oxidative stress and inflammation in biological samples collected from recurrent airway obstruction (RAO)-affected horses and their controls
… inflammatory cells and mucosal biopsies of RAO-affected horses and their controls. Sixteen horses in pairs were used: 8 non-RAO-affected (controls) and 8 RAO-affected horses. Samples from all horses were collected at remission (S1), during environmental challenge (S2) and at recovery (S3). …

The Intradermal Skin Test in the Horse: Value as a Diagnostic Modality in Equine Allergies
… such as equine recurrent airway obstruction (RAO). This study was divided into two experiments. In the first experiment of this study, the hypothesis tested was normal horses would have minimal variability in the wheals formed by intradermal injection of positive control stimulants. This was …

Direct optimization of 3D dose distributions using collimator rotation
… referred to as rotating aperture optimization (RAO). A series of tests is performed to evaluate how a final optimized plan depends on MLC parameters. Imposing constraints on the leaf sequence results in increased efficiency and a simplification of the treatment plan without compromising the …

On the principle of MINQUE for the estimation of variance and covariance components
… thesis, we describe the method of MINQUE (C. R. Rao (1970)) and its various generalizations (C. R. Rao (1971, 1972), Chaubey (1977), P. S. R. S. Rao and Chaubey (1978)). This method can be used if some information about the variance components is available in the form of an a priori guess. …
