A previous study investigated how horizon measurement uncertainty leads to errors in annual irradiance calculations. Those results were based upon determining shading for whole hour periods by testing whether the mid-hour point fell below the horizon. In this study, we test an alternate approach that considers fractional shading during each hourly window. We find only very slight changes in the P90...
Planning for solar power installations requires assessment of potential shading by nearby obstacles on the horizon. A degree of uncertainty exists in measurements of the horizon from the point-of-view of the proposed solar collector. This uncertainty takes the form of errors in the measurement of the azimuth and altitude of obstacles that may cause shading. We modeled irradiance reductions due to...
We use classical mutual information to characterize two photons measured in three mutually unbiased bases. We theoretically and experimentally compare entangled and separable states and find a bound on the information capacity of the pair.
Optical spatial coherence, characterizing correlations between optical fields at distinct points, plays a key role in the understanding of classical and quantum phenomena. Recent decades' technological advances, such as powerful lasers and fast, efficient photon counters enabled the study of nonclassical optical fields. Here, we describe single photon partial coherence, providing a theoretical model...
