This task is challenging, due to the atmospheric conditions that are often complex, including various cloud layers moving in different directions simultaneously.This challenge is addressed by detecting and tracking individual clouds. For this, we developed two distinct ASI nowcasting approaches with four...
but with a dark or gray cloud, the sunlight is scattered in all directions instead of reflected. When warmer air rises through colder regions, the air cools and the moisture in the air
(2014). They first use wavelet filtering to decompose the column density map into a set of structures with different spatial scales. Each of these structures is then modelled as a prolate spheroid oriented in the plane of the sky. Given the assumed orientation of this spheroid, the ...
Clouds are said to be the largest uncertainty in climate models, and I can believe that. Their representation in the models is highly parameterized, each model uses different parameters as well as different values for the same parameters, and so of course, different models give very different re...

The different choice of “control” days for the south, whether all the rainy days of 1949-60 or the north-seeded days of 1969-75, is what crucially affects the comparison. If such large differences-of a magnitude of several standard errors and clearly significant by the usual statistical ...
These two factors influence the behavior in different directions. LF[f] strategies By definition, LF[f] strategies try to execute as many jobs as possible locally, resorting to offloading through strategy f only when the local device is unable to cope with the deadline of a job. Accordingly,...
Unlike other existing methods, such as the moving least-squares method and the principle curve method, our algorithm does not need a thinning process. The idea of our algorithm is intuitive and simple--we make a B-spline curve grow along the tangential directions at its two end- points ...
In the room, Amity, Ed and Em try to find a way to get through to their mom. They’ve tried different things but in the end, they realize money wins out for their mom. Amity again says that their dad would listen. Amity gets upset because she wants to make sure Luz is safe....
Great Schools Ratings are based on student performance on state tests, progress over time, and college readiness, in addition to how effectively schools serve students from different racial, ethnic, and socioeconomic backgrounds. Ratings are on a scale of 1 (below average) to 10 (above average)...
