Six influence factors, such as buried depth, wall thickness, pipe diameter, precipitation level, soil modulus of elasticity, and soil density, are considered in this ANN model. The ANN model is a back propagation (BP) network, and model structure is designed based on MATLAB, in which Neuron...

More specifically, the effects of the orientation of the buried antenna and burial depth and soil moisture are investigated. The experimental results show that, at 7 GHz, additional attenuations of 10, 34, and 40 dB are noted for depointing the underground antenna by 90°, increasing the ...
depth of groundwater and other related information, can be detailed survey and the exploration of groundwater j, solve drinking water, industrial water and agricultural irrigation demand, to great effect to the successful drilling Wells for water, under the general customers the c...
"It is essential to ensure that these cable lines have uninterrupted power so that the city functions normally. Being able to ensure a warm winter for the residents in the freezing temperature through our work gives us the greatest satisfaction," Ge said with a smile on his face. ...
The world’s longest and deepest application to date is the twin-tubesubwaycrossing ofSan FranciscoBay, constructed between 1966 and 1971 with a length of 3.6 miles in a maximum water depth of 135 feet. The 330-foot-long, 48-foot-wide sections were constructed of steel plate and launched ...
Where the minimum coal-seam depth exceeds 250 to 300 metres, it is common to drive vertical shafts. (Poor ground conditions are another factor in selecting a shaft over a slope.) Shafts, too, may be split into separate compartments for fresh air, return air, worker and supply transport, ...
