the subject of geometry and proportions has been regarded as an issue which has a close relationship with architecture. since the entire universe, living beings and the human geometry can be seen clearly, that’s why our unconscious essence has accustomed to these proportions whereby reflection of this mentality can be seen in the architect’s hands and thought in the architecture. it can witness...

Accurate prediction of the fracture geometry before operation a hydraulic (HF) job is important for treatment design. Simplified planar models, which may be applicable to predict in homogeneous and continuous formations, fail case fractured reservoirs laminated formations such as shales. To gain better understanding propagation mechanism their vertical specific, series numerical models were run...

The present hydraulic variable-pitch mechanism of wind turbine uses three hydraulic cylinders to drive three crank and connecting rod mechanisms respectively; the blades are moved with the cranks. The hydraulic variable-pitch mechanism has complex structure, occupies a lot of space and its maintenance is trouble. In order to make up for the shortcomings of hydraulic cylinder variable-pitch syst...

Tractor hydraulic power is used on a wide range of agricultural implements; however, the availability of operational hydraulic data at points other than full engine throttle position is limited. Operators could utilize this hydraulic data to maximize field efficiency and minimize machinery costs when determining suitable machinery for field operations. A field usable hydraulic test apparatus ca...

Wave-induced fluid pressure diffusion (FPD) represents an important mechanism of seismic energy dissipation in fractured media. The associated effects on wave propagation are typically studied considering idealized fracture geometries. Here, we study fracture-geometry-related FPD by numerically computing the frequency-dependent and angle-dependent velocity attenuation models having fractures re...

Hydraulic fracture networks, especially geometry, height growth, and proppant transport within the present a critical influence on productivity evaluation optimization of fracturing parameters. However, information about hydraulic networks in post-fractured formations is seldom available. In this study, characteristics (density orientation) fractures were obtained from field observations cores ...
