Adaptive beamforming of steerable array monopole antenna for WLAN application [PDF]
, 2018 The modern communication systems are using smart portable devices that operate on WLAN frequency of 2.45 GHz. One of the serious limitations of handled devices is difficult to achieve a direct connection between the transmitter and receiver. Therefore, a

Near Surface Geophysics, Volume 23, Issue 2, Page 105-120, April 2025.Abstract Degradation within a manmade earth embankment structure is often unobservable from the surface. In order to evaluate the structural integrity of earth embankment levees and dams and identify subsurface zones of weakness that may result in the future failures of such structures, various geophysical methods have been proposed as effective ...

Engineering Reports, Volume 7, Issue 3, March 2025.This study proposed a method of modeling and analysis of dam slope plane deformation based on multi‐points monitoring data. Firstly, based on the sort out and analyze of actual monitoring data of the Hongjiadu CFRD, the deformation property of the dam has been mastered.

Stepped Spillway Flows and Air Entrainment [PDF]
, 1993 Stepped spillways have become a popular method for handling flood releases. The steps increase significantly the rate of energy dissipation taking place on the spillway face and reduce the size of the required downstream energy dissipation basin.

Journal of Flood Risk Management, Volume 18, Issue 1, March 2025.Abstract Off‐stream reservoirs are artificial water storage structures that increase the flood risk of an area. In some places, related risk reduction plans are based on a risk classification of these structures, which follows local water resource management regulations. These classification methods typically follow deterministic qualitative guidelines
