The autecology of the adult horn fly, Haematobia irritans (L.), (Diptera: Muscidae) on dairy cattle
… wind direction, and the amount of sunlight or cloud coverage were recorded. Usually there was a significant difference between the number of horn flies on Holstein and that on Guernsey and Jersey heifers. Horn flies generally preferred the dark colored areas of bicolored cattle during the hours …

Mapping exoplanet clouds and albedo from phase curves and spectra
… to analyze the composition and occurrence of clouds on tidally locked exoplanets. We confirm that non-uniform cloud coverage on the dayside of tidally locked exoplanets will affect the magnitude and location of the maximum of the phase curve. We then apply the models to the exoplanet Kepler-7b …

Towards Autonomous Cotton Yield Monitoring
… yield estimates were based on the cotton unit coverage (CUC) observed as the cotton boll image signal density. The cotton boll signals were extracted via their diffusion potential in the image intensity space. This was robust to gradients in illumination caused by cloud coverage as well as …

Three Essays in Applied Microeconomics
… human interpreters and images on the accuracy of cloud interpretation for satellite images in an online experiment, using a fractional logit model. The results indicate that an image with higher cloud coverage and/or larger brightness is more likely to receive higher accuracy, and the more time …

Vision-Based Solar Forecasting with Deep Learning
… spatio-temporal variability induced by the cloud cover dynamics causes a large uncertainty in solar power supply, limiting its contribution to the energy mix. The diverse solutions developed to increase the reliability of solar energy, including improved storage systems or demand …

The influence of heat transport on Arctic amplification
… through decreased surface albedo and increased cloud coverage. We also find that while the changes in atmosphere heat transport into the Arctic circle at 66.5∘N are on the same order as the changes in ocean heat transport, they are not correlated with Arctic amplification.

Optimal locations for the ground segment of optical space communications networks
… for the laser beam to penetrate atmospheric clouds. Geographic diversity of ground stations has been proposed as an alternative to mitigate these effects. This thesis uses the systems architecture approach to analyze different architectures for the ground segment of an optical space …

The Observation, Modeling, and Retrieval of Bio-Optical Properties for Coastal Waters of the Southern Chesapeake Bay
… from IOPs and sky conditions (e.g. cloud coverage and solar zenith angle). Compared to the significant overestimation of the simple <em>Gordon</em> [1989] model for particle-rich environments, PZ06_<em>Ed</em> agreed with <em>Hydrolight</em>® with < 6% of the root-mean-square (RMS) …

Towards Generalized Characterization of Exoplanet Atmospheres with Transit Spectroscopy
… that a combination of models including variable cloud coverage, prominent opacity sources, and high-precision optical and infrared spectra with current facilities enable constraints on cloud/haze properties and chemical abundances. Second, we apply our atmospheric retrieval framework to a large …

Precision Nutrition Tools to Support Extensive Forage-Based Livestock Systems
… for their influence on assigned BCS, including cloud coverage, animal breed, individual scorer, and scorer's location. Random forest regressions were derived to evaluate the ability of the thermal camera to accurately BCS horses and cows with data split into three parts. After models were …

Design of high-performance luminescent solar concentrators based on aggregation-induced emitters in organic-inorganic hybrid waveguides
… use in built environment and regions with high cloud coverage. In addition, they are often available in a variety of colours and geometries, ideal for architectural design. Nevertheless, the optical performance of an LSC is often undermined by the effect of aggregation-caused quenching (ACQ), …
