Global Sporadic‐E Prediction and Climatology Using Deep Learning
Space Weather, Volume 23, Issue 5, May 2025.Abstract Sporadic‐E Es $\left({E}_{s}\right)$ is an ionospheric phenomenon defined by strong layers of plasma which may interfere with radio wave propagation. In this work, we develop deep learning models to improve the understanding of Es ${E}_{s}$, including the presence, intensity and height of the layers. We developed three separate models.

Jurnal Teknik Sipil, 2018 Abstract: Takengon - Blangkejeren road is one of the cross national roads connecting Central Aceh Regency with Gayo Lues Regency. This road is in the mountainous terrain and often passed by heavy loaded vehicles so that often damaged. To overcome the frequent damage to this road segment, it is necessary to conduct a research on road pavement damage ...

Hydrological Processes, Volume 39, Issue 2, February 2025.In two contrasting hydroclimates, the energy‐limited Scotland and moisture‐limited NE Germany, vegetation type was found to be a key control on urban ecohydrological partitioning. Grass encouraged groundwater recharge, whilst evergreen shrubs in Scotland and mature trees in Germany elevated transpiration. In Germany, impacts to hydrological functioning

Asphalt Pavement Roughness Prediction Based on Gray GM(1,1|sin) Model
International Journal of Computational Intelligence SystemsRoughness is a comprehensive assessment indicator of pavement performance. Prediction of pavement roughness exhibits great difficulties by using traditional methods such as mechanistic-empirical method and regression method. Considering the fact that the

Regional Freight Movement and Its Impact on Air Quality: Simulation of Freight Traffic and Pavement Maintenance Operations [PDF]
, 2017 Freight movement emits greenhouse gases (GHGs) and deteriorates pavement - thereby causing additional emissions from pavement maintenance and rehabilitation (M&R) treatments. This study predicts the carbon dioxide equivalent GHGs (CO2eGHGs) emission from
