Gust-front factor: A new framework for the analysis of wind load effects in gust-fronts
In comparison with atmospheric boundary-layer winds, which are customarily treated as stationary, gust-front winds such as a thunderstorm/downburst exhibit strong nonstationarity. In storms characterized by a gust-front, wind speed changes rapidly during a short time period. In order to realistically describe attendant loads effects, a new analysis framework is presented which is named the gust...
متن کاملPhysical and numerical modeling of downburst generated gust fronts
This paper presents three different schemes for modeling and analyzing the effects of gust fronts resulting from downbursts on structures. These schemes include: (i) the utilization of a manually controlled, pivoted flat plate that can be rotated to a high angle of incidence in a traditional low speed wind tunnel facility to mimic the kinematics and dynamics of a gust front and to quantify thei...
متن کاملMachine Intelligent Gust Front Detection
I] Techniques of low-level machine intelligence, originally developed at Lincoln Laboratory to recognize military ground vehicles obscured by camouflage and foliage, are being used to detect gust fronts in Doppler weather radar imagery. This Machine Intelligent Gust Front Algorithm (MIGFA) is part of a suite of hazardous-weather-detection functions being developed under contract with the Federa...

متن کاملAutomatic and statistically robust spatio-temporal detection and tracking of fusion plasma turbulent fronts
The controlled production of thermo-nuclear fusion energy is critical for providing an alternative, environmentally friendly, and renewable energy source on our planet. The technical challenge is to stabilize the dynamic turbulent flow of hot plasma in magnetic fields in a fusion energy reactor. More specifically, the issue is how to control fusion plasma instabilities, or turbulence–an analogy...
