Biaxial Equatorial Solar Tracker with High Precision and Low Consumption: Modelling and Realization
International Journal of Photoenergy, Volume 2021, Issue 1, 2021., 2021 The solar tracker is a mechanism that helps the photovoltaic panel to maximize its performance, while keeping it oriented towards direct solar radiation. In order to specify tracking, most solar trackers use two axes, one horizontal and the other vertical, which implies an increase of the consumed energy and a decrease in precision, since we have to ...

Accuracy of magnitudes in pre‐telescopic star catalogs
Astronomische Nachrichten, Volume 341, Issue 8, Page 827-840, October 2020., 2020 Abstract Historical star magnitudes from catalogs by Ptolemy (137 AD), al‐Sūfī (964), and Tycho Brahe (1602/27) are converted to the Johnson V‐mag scale and compared to modern‐day values from the HIPPARCOS catalog. The deviations (or “errors”) are tested for dependencies on three different observational influences.

Weight Distribution of Periodic Errors and Optimal/Anti‐Optimal Linear Codes
Journal of Mathematics, Volume 2014, Issue 1, 2014., 2014 The paper discusses weight distribution of periodic errors and then the optimal case on bounds of parity check digits for (n = n1 + n2, k) linear codes over GF(q) that corrects all periodic errors of order r in the first block of length n1 and all periodic errors of order s in the second block of length n2 and no others. Further, we extend the study to
