An experimental study on characterization of physical properties of ultramafic rocks and controls on evolution of fracture permeability during serpentinization at hydrothermal conditions
… in a triaxial loading machine at an effective pressure of 30 MPa, and temperature of 260°C, simulating a depth of 2 km under hydrostatic conditions. Fracture permeability decreased by one to two orders of magnitude during the 200 to 340 hour experiments. Electron microprobe and SEM data …

Automatic type curve matching for predicting gas wells production
… curves unlike the other type curves accounts the pressure dependency of gas properties and the effect of non-darcy factor. The sensitivity of Aminian type curves to non-darcy factor makes them hard to match with naked eyes.;Sfrac is a computer program generates type curves using conventional …

Assessing the Impact of International Human Rights Pressures: the Dominican Republic and China
… assess the impact of international human rights pressure on state compliance with international human rights norms and conventions. In investigating the impact of human rights pressure on states, I hypothesize that certain conditions are helpful. The first condition is the absence of a strong …

Gas production forecasting using automatic type curve matching
… of the proposed theoretical solutions. Thus, the pressure dependency of gas viscosity and compressibility, as well as the pressure loss owing to non-Darcy flow, make of these solutions quite accurate to model gas wells decline.;Different history productions were matched with these type curves …

Effects of Stack Pressure on High Performance Lithium-Ion Batteries
… works have shown that applying mechanical pressure to the through-plane surface of pouch cells can have both beneficial and detrimental effects on cell perfor- mance and lifetime. Despite this, there is little work exploring the implications of this performance difference when discussing …

Quantitative monitoring of gas injection, exsolution and dissolution using 4D seismic
… for the reverse process, in which reservoir pressure builds up, it is noted that it is not only the fluid type that impacts the gas when it goes back into solution, but also other reservoir properties such as relative permeability curves, transmissibility, Kv/Kh, and the injection/production …

Geosynthetic Reinforced Soil: Numerical and Mathematical Analysis of Laboratory Triaxial Compression Tests
… component was modified to incorporate confining pressure dependency of friction angle and dilation parameters, while retaining the constitutive model's ability to represent nonlinear stress-strain response and plastic yield. Procedures to obtain the parameter values from drained triaxial …

Kinetics of propylene disproportionation over a tungsten oxide on silica catalyst
… Temperatures of 399° to 454° Centigrade and pressures from one to nine atmospheres were used. The experimental data were well correlated by assuming that a Langmuir-Hinshelwood, dual-site surface reaction was the rate controlling step in the reaction mechanism. The mechanism parameters and …

Head-dependent modelling and optimisation of water distribution systems
… consequently they are incapable of simulating pressure-deficient (infeasible) solutions accurately. When simulating a pressure-deficient network, results produced by demand-driven analysis model are highly unreliable and misleading. This thesis is concerned with the development and application …
