    • Full-AC load flow constitutes a core computation in power system analysis. The present invention provides a performance gain with a hardware implementation of a sparse-linear solver using a Field Programmable Gate Array (FPGA). The invention also relates to the design, simulation, and hardware verification of a static transmission line model for analog power flow computation. Operational transconductance amplifiers are employed in the model based on a previously proposed DC emulation technique of power flow computation, and provide reconfigurability of transmission line parameters via transconductance gain. The invention also uses Analog Behavioral Models (ABMs) in an efficient strategy for designing analog emulation engines for large-scale power system computation. Results of PSpice simulations of these emulation circuits are compared with industrial grade numerical simulations for validation. The application is also concerned with the development of a generator model using analog circuits for load flow emulation for power system analysis to reduce computation time. The generator model includes reconfigurable parameters using operational transconductance amplifiers (OTAs). The circuit module is used with other reconfigurable circuits, i.e., transmission lines and loads.

    • An invention for coherent array image formation and restoration is taught. The invention is applicable for both 2D and 3D imaging using either 1D or 2D arrays, respectively. A transducer array is subdivided into subarrays, each subarray having a number of adjacent array elements. All elements of each subarray transmit and receive in parallel. The signals received from each subarray are delayed and summed to form scan lines, or beams. The low-beam-rate beams formed from each subarray are upsampled and interpolated prior to forming high-beam-rate images. Depending on the subarray geometry, a subarray-dependent restoration filter is also applied to the subarray beams. The restored beams from each subarray are combined to form the final high-beam-rate image. The invention significantly reduces the front-end hardware complexity compared to conventional methods such as full phased array imaging with comparable image quality.
    • 教导了相干阵列图像形成和恢复的发明。 本发明分别适用于使用1D或2D阵列的2D和3D成像。 换能器阵列被细分为子阵列,每个子阵列具有多个相邻的阵列元件。 每个子阵列的所有元素并行传输和接收。 从每个子阵列接收的信号被延迟并相加以形成扫描线或光束。 在形成高光束速率图像之前,从每个子阵列形成的低光束速率光束被上采样和内插。 根据子阵列几何,子阵列依赖的恢复滤波器也被应用于子阵列波束。 来自每个子阵列的恢复的波束被组合以形成最终的高光束速率图像。 与常规方法相比,本发明显着降低了前端硬件复杂性,例如具有可比较图像质量的全相控阵列成像。

    • Methods and systems are provided for favorably altering the chemomechanical properties of subterranean formations using treatment fluids comprising surfactants and halide salts. Methods for treating formations comprise the steps of introducing a chemomechanical treatment fluid into the formation and allowing the treatment fluid to interact with the formation to alter its petrochemical properties in various ways. Depending on the application, the chemomechanical treatment fluid may comprise a base fluid, a halide salt and an amphoteric or nonamphoteric surfactant where the surfactant is dissolved in the base fluid at a concentration below its critical micelle concentration. Applications of use involving the chemomechanical treatment fluids include treatment operations, secondary recovery operations, drilling operations, and any other operation that would benefit from the formation property modifications described herein. Subterranean formation properties that may to be varied by the chemomechanical treatment fluid include fracture toughness, compressive strength, and tensile strength.
