The concept of Supervisory Control and Data Acquisition (SCADA) system was introduced in the late sixties and subsequently the Energy Management System (EMS) solution with set of functionalities that relied on SCADA data was introduced in the seventies. This EMS design was based on the notion that power system goes through distinct states such as normal, alert, emergency and restorative, and he...

Following an initiative formalized in April 2016—formally known as ARL West—between the U.S. Army Research Laboratory (ARL) and University of Southern California’s Institute for Creative Technologies (USC ICT), a field experiment was coordinated and executed in the summer of 2016 by ARL, USC ICT, and Headwall Photonics. The purpose was to image part of the USC main campus in Los Angeles, USA, u...

Inhomogeneous media identification is the problem of determining the physical properties of an unknown inhomogeneity from its response to various interrogating modalities. This response, recorded in measured data, comes as a result of the interaction of the inhomogeneity with an exciting physical field. Inhomogeneous media identification is mathematically modeled as the problem of determining t...

This extended abstract describes a field test of the Field Information Support Tool (FIST) during the international Humanitarian Assistance and Disaster Relief exercise Pacific Endeavor 2010, in Singapore and the Philippines.

Due to the dynamics of the environment and the variability on the product usage, product units in the field are usually exposed to varying failure-causing stresses. Some products are equipped with sensors and smart chips that measure and record usage/ environmental information over the life of the product. For some products, it is possible to track environmental variables dynamically, even in r...

Spatially heterogeneous permeability data from several sites is reviewed. The spatial correlations in this data are valid (i.e. statistically signi cant) for short distances only. Multifractal power-normal distributions t this data about as well as the more commonly used exponential models, while better for long distance correlations inferred indirectly from hydrological studies, with the data ...

Product units in service may be discarded even before they have failed. This paper discusses the need to consider such discarded units in analyzing eld failure data. Approaches based on maximum likelihood (ML) and conventional cumulative hazard (CH) methods are described and evaluated for their accuracy in estimating the parameters of failure time distributions. Simulation results showed that t...

The Three Gorges are the areas in which the geological disasters are very serious. There often happen great landslide disasters, which brings tremendous threat to normal running of the Three Gorge Dam and the properties and lives of the residents in the reservoir. So landslide susceptibility analysis is an important task of prevention and cure of landslides in the Three Gorges. In this paper, l...
