The current educational development in the Guangdong-Hong Kong-Macao Greater Bay Area is not enough to support construction of a world-class bay area, so education reform and innovation face many challenges. This study systematically sorts out challenges faced by Area, starting from interpretation talent training standards new era, proposes that should re-understand implement national right SAR...

in this work, 137cs activity concentration of soil in five depths and in six meteorology stations in terms of bq/kg has been measured. for each thirty soil's samples, parameters such as kind of soil, density and hydraulic coefficient of transmission were determined. correlation coefficient between 137cs activity concentration and raining average, hydraulic coefficient of transmission and s...

Abstract In the lighting conditions such as hazing, raining, and weak condition, accuracy of traffic sign recognition is not very high due to missed detection or incorrect positioning. this article, we propose a (TSR) algorithm based on Faster R-CNN YOLOv5. The road signs were detected from driver’s point view was assisted by satellite images. First, conduct image preprocessing using guided fil...

In this paper, an unsupervised-learning method for events-identification in φ-OTDR fiber-optic distributed vibration sensor is proposed. The different vibration-events including blowing, raining, direct and indirect hitting, noise-induced false are clustered by the k-means algorithm. equivalent classification accuracy of 99.4% has been obtained, compared with actual classes experiment. With clu...

Innovated method applied to adapt Hatra Bridge on Tharthar valley as discharge monitoring station, estimate the water income of near site proposed dam. The section was geometrically surveyed before first rainfall storm build equation relationship between level and area flow which required for estimation.
 Six flood waves were monitored along period raining season 2012-2013, velocity measur...

Abstract. When nuclear power plants are dismantled, only a small portion is heavily contaminated with radioactivity and must be stored in repository. The remaining material, mainly concrete rubble (construction waste), decontaminated if necessary can conventional surface landfills after clearance. focus of this work on the modelling such radioactive substances during raining events. influence h...
