Identification of Flight Area Identification Plate Based on an Improved MSER Algorithm

International Journal of Aerospace Engineering, 2022
In this study, an algorithm based on improved maximum stable extremum region (MSER) was used to match and recognize the content of signage in the airfield, so as to overcome unrecognizable signage caused by low visibility or an overlapping field of view ...

Thermokarst Landscape Development Detected by Multiple-Geospatial Data in Churapcha, Eastern Siberia

Frontiers in Earth Science, 2021
Thermokarst is a typical process that indicates widespread permafrost degradation in yedoma landscapes. The Lena-Aldan interfluvial area in Central Yakutia in eastern Siberia is now facing extensive landscape changes with surface subsidence due to ...

Leveraging automated radio telemetry to understand avian presence on a military airfield

Frontiers in Conservation Science
Bird-aircraft collisions, or bird strikes, are a costly incident for the aviation industry. Bird strikes occur most often at low altitudes, which means that the airfield itself is an area of high risk for strikes to occur.

Scaling turbulence drives the general circulation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous
