Estimating the state of epidemics spreading with graph neural networks
(Springer Netherlands, 2022-01-21)Abstract When an epidemic spreads into a population, it is often impractical or impossible to continuously monitor all subjects involved. As an alternative, we propose using algorithmic solutions that can ... -
Estimating the value of demand-side management in low-cost, solar micro-grids
(Elsevier, 2018-08)Demand-side management has the potential to reduce the cost of solar based community micro-grids and solar home systems for electricity access. This paper presents a methodology for optimal least-cost sizing of generation ... -
Estimating tropical cyclone precipitation risk in Texas
(American Geophysical Union, 2013-12)This paper uses a new rainfall algorithm to simulate the long-term tropical cyclone precipitation (TCP) climatology in Texas based on synthetic tropical cyclones generated from National Center for Atmospheric Research/National ... -
Estimating Welfare In Insurance Markets Using Variation in Prices
(MIT Press Journals, 2010-08)We provide a graphical illustration of how standard consumer and producer theory can be used to quantify the welfare loss associated with inefficient pricing in insurance markets with selection. We then show how this welfare ... -
Estimation and empirical properties of a firm-year measure of accounting conservatism
(Elsevier, 2009-09)We estimate a firm-year measure of accounting conservatism, examine its empirical properties as a metric, and illustrate applications by testing new hypotheses that shed further light on the nature and effects of conservatism. ... -
Estimation for decentralized safety control under communication delay and measurement uncertainty
(Elsevier BV, 2015-11)This paper addresses the design of a decentralized safety controller for two agents, subject to communication delay and imperfect measurements. The control objective is to ensure safety, meaning that the state of the ... -
Estimation of Aircraft Taxi-out Fuel Burn using Flight Data Recorder Archives
(American Institute of Aeronautics and Astronautics (AIAA), 2011-08)The taxi-out phase of a flight accounts for a significant fraction of total fuel burn for aircraft. In addition, surface fuel burn is also a major contributor to CO 2 emissions in the vicinity of airports. It is therefore ... -
Estimation of Arrival-Departure Capacity Tradeoffs in Multi-Airport Systems
(Institute of Electrical and Electronics Engineers, 2009-12)The accurate estimation of airport capacity is critical for the efficient planning of landing and takeoff operations, and the mitigation of congestion-induced delays. The analysis of tradeoffs between arrival and departure ... -
Estimation of Atlantic Tropical Cyclone Rainfall Frequency in the United States
(American Meteorological Society, 2019-08)Tropical cyclones pose a significant flood risk to vast land regions in their path because of extreme precipitation. Thus it is imperative to quantitatively assess this risk. This study compares exceedance frequencies of ... -
Estimation of axial curvature of anterior sclera: correlation between axial length and anterior scleral curvature as affected by angle kappa
(BioMed Central, 2016-10)Background: Though the development and fitting of scleral contact lenses are expanding steadily, there is no simple method to provide scleral metrics for scleral contact lens fitting yet. The aim of this study was to ... -
Estimation of changes in instantaneous aortic blood flow by the analysis of arterial blood pressure
(American Physiological Society, 2012-03)The purpose of this study was to introduce and validate a new algorithm to estimate instantaneous aortic blood flow (ABF) by mathematical analysis of arterial blood pressure (ABP) waveforms. The algorithm is based on an ... -
Estimation of clinical trial success rates and related parameters
(Oxford University Press (OUP), 2018-01)Previous estimates of drug development success rates rely on relatively small samples from databases curated by the pharmaceutical industry and are subject to potential selection biases. Using a sample of 406 038 entries ... -
Estimation of elastic constants for HTI media using Gauss-Newton and full-Newton multiparameter full-waveform inversion
(Society of Exploration Geophysicists, 2016-07)In seismic full-waveform inversion (FWI), subsurface parameters are estimated by iteratively minimizing the difference between the modeled and the observed data. We have considered the problem of estimating the elastic ... -
Estimation of evaporation over the upper Blue Nile basin by combining observations from satellites and river flow gauges
(American Geophysical Union, 2016-01)Reliable estimates of regional evapotranspiration are necessary to improve water resources management and planning. However, direct measurements of evaporation are expensive and difficult to obtain. Some of the difficulties ... -
Estimation of functionals of sparse covariance matrices
(Institute of Mathematical Statistics, 2015-12)High-dimensional statistical tests often ignore correlations to gain simplicity and stability leading to null distributions that depend on functionals of correlation matrices such as their Frobenius norm and other Lr norms. ... -
Estimation of grain boundary segregation enthalpy and its role in stable nanocrystalline alloy design
(Cambridge University Press (Materials Research Society), 2013-08)Grain boundary segregation provides a method for stabilization of nanocrystalline metals—an alloying element that will segregate to the boundaries can lower the grain boundary energy, attenuating the driving force for grain ... -
Estimation of Instantaneous Complex Dynamics through Lyapunov Exponents: A Study on Heartbeat Dynamics
(Public Library of Science, 2014-08)Measures of nonlinearity and complexity, and in particular the study of Lyapunov exponents, have been increasingly used to characterize dynamical properties of a wide range of biological nonlinear systems, including ... -
Estimation of Landscape Soil Water Losses from Satellite Observations of Soil Moisture
(American Meteorological Society, 2018-04)This study presents an observation-driven technique to delineate the dominant boundaries and temporal shifts between different hydrologic regimes over the contiguous United States (CONUS). The energy- and water-limited ... -
Estimation of local concentration from measurements of stochastic adsorption dynamics using carbon nanotube-based sensors
(Springer US, 2015-08)This paper proposes a maximum likelihood estimation (MLE) method for estimating time varying local concentration of the target molecule proximate to the sensor from the time profile of monomolecular adsorption and desorption ... -
Estimation of many-body quantum Hamiltonians via compressive sensing
(American Physical Society, 2011-07)We develop an efficient and robust approach for quantum measurement of nearly sparse many-body quantum Hamiltonians based on the method of compressive sensing. This work demonstrates that with only O(sln(d)) experimental ...
