An Introduction to Inverse Problems in Partial Differential Equations for Physicists, Scientists and Engineersert an input/output mapping. When the unknown physical properties are characterized by a small number of constant parameters, the problem is referred to as a parameter identification problem and in such cases the input/output mapping is often simple enough that important properties of the map become

Interpretation of Field Tests in Low Permeability Fractured Media. Recent Experiencessucceeded in producing models capable of predicting independent data sets. However, in recent times, we have faced a set of tests performed in very low conductive, highly heterogeneous granite where using exclusively the standard procedure has not produced good results. Difficulties include the foll

New Front Limitation Algorithmtion cannot be applied successfully without modifications to reduce the computational time by maintaining sufficient accuracy. This paper presents a new effective approach (so-called FRONT LIMITATION algorithm) to solve the advection-dispersion equation without restriction for grid PECLET number. Th

Identification and Reduction of Model Structure for Modeling Distributed Parameter Systemsr of using model .. to replace model .. is defined as a weighted sum of their distances in both observation and prediction spaces. The value of so defined structure error can be obtained by solving a max-min problem. In order to select an appropriate complexity of model structure, the concept of ext

Results from a Comparison of Geostatistical Inverse Techniques for Groundwater Flowated to assess its suitability for isolating transuranic wastes generated by defense programs in the U.S. The proposed repository is located within the bedded salt of the Salado Formation at a depth of about 660 meters. The Culebra Dolomite, located within the Rustler Formation at a depth of about 2

Identification of the Hydraulic Diffusivity of a Soil by Inverse Method with Dual-Energy Gamma Ray Attenuation Measurementsify hydraulic diffusivity. A transient physical process of water transport is required for this, for which a dynamic imbibition experiment was chosen. Time variations of moisture content are measured at various locations by dual-energy gamma ray attenuation. The diffusion transport occurring in this
