Inverse conductivity problem for inaccurate measurements
In order to determine the conductivity of a body or of a region of the Earth using electrical prospecting, currents are injected on the surface, surface voltage responses are measured, and the data are inverted to a conductivity distribution. In the present paper a new approach to the inverse problem is considered for measurements containing noise in which data are optimally chosen using availa...
متن کاملInverse Problem for a Heat Equation with Piecewise-constant Conductivity
We consider the inverse problem of the identification of a piecewiseconstant conductivity in a bar given the extra information of the heat flux through one end of the bar. Our theoretical results show that such an identification is unique. This approach utilizes a ”layer peeling” argument. A computational algorithm based on this method is proposed and implemented. The advantage of this algorith...
متن کاملEffective Unsaturated Hydraulic Conductivity
Steady-state and transient one-dimensional unsaturated flow in vertically stratified porous media are examined. Saturated hydraulic conductivity and the alpha parameter of the exponential hydraulic conductivity function were assumed to vary from soil layer to soil layer. The use of effective unsaturated hydraulic conductivity to compute matric potential in the soil profile is demonstrated. Resu...
متن کاملThe hydraulic conductivity of MatrigelTM
In this study, we measured the specific hydraulic conductivity (K) of MatrigelTM at 1% and 2% concentrations as a function of perfusion pressure (0 to 100 mmHg) and compared the results to predictions from two models: a fiber matrix model that predicted K of the gel based upon its composition, and a biphasic model that predicted changes in K caused by pressure induced compaction of the gels. Th...
متن کاملEEG inverse problem solution with minimal influence of the conductivity
In this paper, we propose a novel method that improves the accuracy of the estimation of neural electrical dipoles when solving the EEG inverse problem. A spherical head model is used where we limit the influence of the unknown conductivity brain-skull ratio on the inverse problem. We redefine the cost function that is used in the EEG problem where only useful information is used as input in th...
