Trepol on the Dnieper, located between Kyiv and Vytachyov, is mentioned in the chronicles since the 11th century. At that time, Trepol was the largest city on the Dnieper trade route between Kyiv and Pereyaslav. Near Trepol there was a crossing over the Dnieper and a junction of important roads. We owe many ideas about the city in the chronicles to this circumstance. However, systematic archaeological research of this city was not carried out.

Abstract:
Wind energy is rapidly growing around the world as non-renewable energy sources are being phased out. To maximize the energy production, it is crucial to construct new wind turbines at locations where the average wind speed is high. An accurate wind assessment of a new potential site is thus essential in the development of new wind farms. Linearized codes (codes based on simplified models) such as Orfeus and WAsP have seen frequent use in the wind industry as a tool for wind resource assessment since they offer reasonable accuracy at a relatively low computational cost.

In this study, the non-dimensional gradient functions for water vapor (Φq) and carbon dioxide (Φc) in the marine boundary layer have principally been studied.

Abstract Wind profiles and turbulence were measured in the atmospheric surface layer between 2.6 and 18.1 m above deep ocean waves. The profiles were compared to those predicted from Monin-Obukhov (M-O) similarity theory using constants representative of over land experiments. Under low wind, slightly unstable conditions, measured profiles show significantly greater (less) shear at the upper (lower) heights than is predicted by M-O similarity. For high wind speeds there is better agreement. A von Karman constant of 0.40 is calculated, in agreement with over land results.

It is now customary to consider atmospheric aerosol as a passive conservative admixture in the atmosphere, that is, it does not disappear and fully floats by the wind vortexes.

Abstract:
We describe what we believe is the first effort to develop a physics-informed neural network (PINN) to predict sound propagation through the atmospheric boundary layer. PINN is a recent innovation in the application of deep learning to simulate physics. The motivation is to combine the strengths of data-driven models and physics models, thereby producing a regularized surrogate model using less data than a purely data-driven model. In a PINN, the data-driven loss function is augmented with penalty terms for deviations from the underlying physics, e.g., a governing equation or a boundary condit
