A multi-agent system for automated post-fault disturbance analysis
… privatised electricity industry, post-fault disturbance analysis is becoming an increasingly challenging prospect for protection engineers. Not only must they be proficient at operating a diverse range of data gathering tools but they must also be able to spend the time necessary to interpret …

Power System Disturbance Analysis and Detection Based on Wide-Area Measurements
… for understanding and responding to power system disturbances and cascading failures. The North American Frequency Monitoring Network (FNET) takes GPS-synchronized wide-area measurements in a low-cost, easily deployable manner at the 120 V distribution level, which presents more opportunities to …

A structurally coupled disturbance analysis method using dynamic mass measurement techniques, with application to spacecraft-reaction wheel systems
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2001.

Evaluation of linear DC motor actuators for control of large space structures
… the structure due to the actuator compensation. Disturbance analysis was performed to quantify the effect of corrupted measurements on the purity of force generated by the actuator.

Dynamics of multi-body space interferometers including reaction wheel gyroscopic stiffening effects : structurally connected and electromagnetic formation of flying architectures
… connected interferometers, we develop a coupled disturbance analysis method that accurately predicts a space telescope's optical performance in the presence of reaction wheel vibrational disturbances. This method "couples" a reaction wheel to a structure using estimates of the accelerances (or …

A QUALITATIVE APPROACH TO UNDERSTANDING THE RELATIONSHIP BETWEEN INTERPERSONAL COMMUNICATION AND THIN DEPICTING MEDIA USE AMONG COLLEGE-AGED FEMALES
… influences of these conversations on body image disturbance. Analysis of results revealed three implications of talk about thin depicting media: (a) the women in this sample seem to understand or acknowledge that media role models are unrealistic and do not provide relevant models for comparison, …

American rivers are transporting more sediment in less time
… influence of hydroclimatic forcing and land-use disturbance. Analysis of those drivers reveals that deforestation, urban expansion, and intensifying precipitation events collectively drive the observed acceleration and concentration of sediment transport. By reconstructing a detailed sediment …

A Methodology to Assess and Rank the Effects of Hidden Failures in Protection Schemes based on Regions of Vulnerability and Index of Severity
Wide-area disturbances are power outages occurring over large geographical regions that dramatically affect the power system reliability, causing interruptions of the electric supply to residential, commercial, and industrial users. Historically, wide-area disturbances have greatly affected …

Performance assessment and enhancement of precision controlled structures during conceptual design
… flexible structure subjected to various disturbances. It is advantageous to assess the performance of initial concepts of these precision systems early in the design stage to aid in the requirements flowdown and resource allocation process. A complete end-to-end performance assessment …

Influence of Multiple Disturbances on Stream Structure and Function
We investigated the influence of multiple disturbances on ecosystem structure and function in a headwater stream adjacent to an abandoned arsenic mine using an upstream (reference) and downstream (mine-influenced) comparative reach approach. In this study, floods were addressed as a pulse …
