Abstract: A system for detecting an object in a subsurface environment includes a first recorder of a vertical electromagnetic component, including first pair of polarization orientation components, of an electromagnetic field in a region of interest, a second recorder of an orthogonal electromagnetic component, including second pair of polarization orientation components, of the electromagnetic field in the region of interest, at least one processor configured to derive a pair of transfer functions that relates the vertical electromagnetic component and the orthogonal electromagnetic component of the electromagnetic field for each of the polarization orientation components, at least one processor configured to determine a simulation of the pair of transfer functions for a given impedance distribution, and at least one processor configured to infer a subsurface impedance map using the pair of transfer functions of the recorded data and the simulation of the pair of transfer functions.

Abstract: A computer-implemented method is presented for performing matrix sketching by employing an analog crossbar architecture. The method includes low rank updating a first matrix for a first period of time, copying the first matrix into a dynamic correction computing device, switching to a second matrix to low rank update the second matrix for a second period of time, as the second matrix is low rank updated, feeding the first matrix with first stochastic pulses to reset the first matrix back to a first matrix symmetry point, copying the second matrix into the dynamic correction computing device, switching back to the first matrix to low rank update the first matrix for a third period of time, and as the first matrix is low rank updated, feeding the second matrix with second stochastic pulses to reset the second matrix back to a second matrix symmetry point.

Abstract: Conventional computational simulation and inversion of subsurface flow are expensive, which is wasteful in terms of time and energy consumption. A process for implementation of mathematical techniques such as forward simulation, sensitivity analysis, and inversion to physical microstructure models for subsurface fluid simulation is disclosed. This process not only offers accurate and reliable results, but also is cost effective.

Abstract: Methods and systems for cleaning an optic include cleaning an optic with ultrasonic vibrations. The locations of nodes in a standing wave of the ultrasonic vibrations are changed by changing a frequency of vibration during cleaning.

Abstract: Methods and systems for cleaning an optic include measuring a state of the optic. It is determined whether the optic needs to be cleaned based on the measured state of the optic. The optic is cleaned with ultrasonic vibrations if the optic needs to be cleaned.
