How the morning-afternoon cloudiness asymmetry affects the energy-maximizing azimuth direction of fixed-tilt monofacial solar panels

open access: yesRoyal Society Open Science, 2022
In the Northern Hemisphere, south is the conventional azimuth direction of fixed-tilt monofacial solar panels, because this orientation may maximize the received light energy.

Hydrogen Clouds before Reionization: a Lognormal Model Approach

open access: yes, 2003
We study the baryonic gas clouds (the IGM) in the universe before the reionization with the lognormal model which is shown to be dynamcially legitimate in describing the fluctuation evolution in quasilinear as well as nonlinear regimes in recent years ...

Combining Synthetic Images and Deep Active Learning: Data-Efficient Training of an Industrial Object Detection Model

open access: yesJournal of Imaging
Generating synthetic data is a promising solution to the challenge of limited training data for industrial deep learning applications. However, training on synthetic data and testing on real-world data creates a sim-to-real domain gap. Research has shown

Using an Arbitrary Moment Predictor to Investigate the Optimal Choice of Prognostic Moments in Bulk Cloud Microphysics Schemes

open access: yesJournal of Advances in Modeling Earth Systems, 2019
Most bulk cloud microphysics schemes predict up to three standard properties of hydrometeor size distributions, namely, the mass mixing ratio, number concentration, and reflectivity factor in order of increasing scheme complexity.

New near-IR observations of mesospheric CO2 and H2O clouds on Mars

open access: yes, 2011
Carbon dioxide clouds, which are speculated by models on solar and extra-solar planets, have been recently observed near the equator of Mars. The most comprehensive identification of Martian CO2 ice clouds has been obtained by the near-IR imaging ...

Kinematic Distances to Molecular Clouds identified in the Galactic Ring Survey [PDF]

open access: yes, 2009
Kinematic distances to 750 molecular clouds identified in the 13CO J=1-0 Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey (BU-FCRAO GRS) are derived assuming the Clemens rotation curve of the Galaxy.

Development of a spectrometer for airborne measurement of droplet sizes in clouds [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2015
The objective of this article is to present the development and the validation in flight of an airborne probe that can measure in clouds the size of droplets whose diameters are in the range [20 μm; 200 μm].

Recognizing point clouds using conditional random fields [PDF]

open access: yes, 2014
Detecting objects in cluttered scenes is a necessary step for many robotic tasks and facilitates the interaction of the robot with its environment. Because of the availability of efficient 3D sensing devices as the Kinect, methods for the recognition of ...

NEUTRINO CLOUDS

open access: yesInternational Journal of Modern Physics A, 1998
We consider the possibility that neutrinos (but no other light fermions) are coupled very weakly to an extremely light scalar boson. We first analyze the simple problem of one generation of neutrino and show that, for ranges of parameters that are allowed by existing data, such a system can have serious consequences for the evolution of stars and ...
