Abstract: Stress and fracture modeling using the principal of superposition is provided. A system simulates linearly independent far field stress models for a subsurface earth volume, computing stress, strain, and displacement values based on superposition of independent stress tensors. Based on the precomputed values, the system generates real-time recovery of paleostress values, or, stress, strain, and displacement parameters for any point in the subsurface volume as the user varies far field stress values. The system recovers one or more tectonic events, or a stress tensor represented by a ratio of principal magnitudes and associated orientation, using fault geometry, well bore data (fracture orientation and secondary fault plane data), GPS, InSAR, folded and faulted horizons, tiltmeters, slip and slikenlines on faults. The system uses different geologic data from seismic interpretation, well bore readings, and field observation to provide numerous results, such as predicted fracture propagation based on perturbed stress field.

Abstract: An animal stroke model is provided. The model is useful in the study of brain ischemia andior reperfusion injury and in identification and testing of compounds and interventions useful in the treatment of stroke. The method is carried out in a non-human mammal, such as rat. The method of inducing ischemia and/or reperfusion injury involves exposing a portion of the middle cerebral artery (MCA) and temporarily occluding it at one or more distinct locations, preferably three distinct locations. The model results in highly reproducible and focal infarct sizes, with low rate of mortality during the experimental procedure.
