FederalProbabilistic Model-Based Diagnosis for Electrical Power Systems
National Aeronautics and Space Administration —
We present in this article a case study of the probabilistic approach to model-based diagnosis. Here, the diagnosed system is a real-world electrical power system,...FederalEntropy-based probabilistic fatigue damage prognosis and algorithmic performance comparison
National Aeronautics and Space Administration —
In this paper, a maximum entropy-based general framework for probabilistic fatigue damage prognosis is investigated. The proposed methodology is based on an...FederalGreener Aviation with Virtual Sensors: A Case Study
National Aeronautics and Space Administration —
The environmental impact of aviation is enormous given the fact that in the US alone there are nearly 6 million flights per year of commercial aircraft. This...FederalModel-based prognostics for batteries which estimates useful life and uses a probability density function
National Aeronautics and Space Administration —
This invention develops a mathematical model to describe battery behavior during individual discharge cycles as well as over its cycle life. The basis for the form of...FederalScalable Distributed Change Detection from Astronomy Data Streams using Local, Asynchronous Eigen Monitoring Algorithms
National Aeronautics and Space Administration —
This paper considers the problem of change detection using local distributed eigen monitoring algorithms for next generation of astronomy petascale data pipelines...FederalData Mining in Systems Health Management
National Aeronautics and Space Administration —
This chapter presents theoretical and practical aspects associated to the implementation of a combined model-based/data-driven approach for failure prognostics based...FederalSAR Image Enhancement using Particle Filters
National Aeronautics and Space Administration —
In this paper, we propose a novel approach to reduce the noise in Synthetic Aperture Radar (SAR) images using particle filters. Interpretation of SAR images is a...FederalAccelerated Aging System for Prognostics of Power Semiconductor Devices
National Aeronautics and Space Administration —
Prognostics is an engineering discipline that focuses on estimation of the health state of a component and the prediction of its remaining useful life (RUL) before...FederalOnboard Detection of Snow, Ice, Clouds, and Other Processes
National Aeronautics and Space Administration —
The detection of clouds within a satellite image is essential for retrieving surface geophysical parameters from optical and thermal imagery. Even a small percentage...FederalSpectral Decomposition Algorithm (SDA)
National Aeronautics and Space Administration —
