the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. in this study experimental tests in a glass micromodel w...

studies of the magnetization of fe2o3@pt nanoparticles at room temperature showed that there is superparamagnetic contribution with high saturation magnetization about 12.35(emu/g), and soft ferromagnetic contribution with narrow coercive field about 58(oe). in this paper we fitted the hystersis loop of sample with brillouin function that demonstrating existence of superparamagnetic phase. tota...

AT THE present time the most widely used method of studying the effect of induced anoxemia on the cardiovascular system consists of giving the subjects low oxygen gas (usually 10 per cent) inhalation for approximately twenty minutes and making observations during this period. In previous communications1'the variability of the degree of anoxemia, as measured by the blood arterial oxygen saturati...

Offline crane maneuvers, resulting in zero residual payload swing, have been explored previously using parameterized sets of basis functions. Assumptions usually included an ideal servo response and symmetric inputs. Nonsymmetric maneuvers, in general, do not have closedform basis function solutions. Actuator dynamics further complicate maneuver generation by introducing nonlinearities such as ...
