Accuracy Assessment of the eBee Using RTK and PPK Corrections Methods as a Function of Distance to a GNSS Base Station

Joseph Cerreta et al · Embry-Riddle Aeronautical University · 2023 · ISSN 2374-6793

The use of unmanned aircraft systems to collect data for photogrammetry models has grown significantly in recent years. The accuracy of a photogrammetric model can depend on image georeferencing. The distance from a refe...

Cavitation Diagnostics Based on Self-Tuning VMD for Fluid Machinery with Low-SNR Conditions

Hao Liu et al · KeAi Communications Co., Ltd · 2023 · ISSN 2192-8258

Abstract Variational mode decomposition (VMD) is a suitable tool for processing cavitation-induced vibration signals and is greatly affected by two parameters: the decomposed number K and penalty factor α under strong n...

Coexistence of quantum key distribution and optical communication with amplifiers over multicore fiber

Kong Weiwen et al · Wiley · 2023 · ISSN 2192-8606

In this paper, the influence of classical signals on quantum key distribution (QKD) is studied over multi-core fiber (MCF) when optical amplifiers exist. Firstly, the long-distance simultaneous transmission architectures...

Forecasting virus outbreaks with social media data via neural ordinary differential equations

Nuñez, Matias et al · Nature · 2023 · ISSN 2045-2322

During the Covid-19 pandemic, real-time social media data could in principle be used as an early predictor of a new epidemic wave. This possibility is examined here by employing a neural ordinary differential equation (n...

The Maslov index and some applications to dispersion relations in curved space times

Osorio Morales, Maria Juliana et al · American Institute of Physics · 2023 · ISSN 0022-2488

The aim of the present work is to generalize the results given in Osorio Morales and Santillán [Eur. Phys. J. C 82, 353 (2022)] to a generic situation for causal geodesics. It is argued that these results may be of inte...
