摘要: An inspection device includes a ray source that irradiates an object to be inspected with energy rays, a detection unit that detects energy rays that have passed through the object to be inspected, a displacement mechanism that sets a relative position of the object to be inspected and the ray source by displacing at least one of the object to be inspected and the ray source in relation to the other, an internal image generation unit that generates an internal image of the object to be inspected based on a detection amount distribution of the energy rays detected by the detection unit, and a control unit that controls the displacement mechanism based on the detection amount distribution of the energy rays detected by the detection unit.

摘要: A system for non-destructive evaluation of an object uses a spherical coordinate system to control two robotic arms. In some examples, the system includes a radiation source coupled to one robotic arm, a radiation detector coupled to the other robotic arm; and a control unit configured to determine, based on input, a first position located on a first surface of a first sphere within the spherical coordinate system; determine, based on the input, a second position located on a second surface of a second sphere within the spherical coordinate system, wherein the second position is located opposite a midpoint of the spherical coordinate system from the first position; and control a motion of the source robotic arm and the detector robotic arm such that the radiation source and the radiation detector move to different ones of the first position and the second position.

摘要: A method for determining porosity of a part is provided. The method includes: determining scan data of the part, the scan data including data of a plurality of sequential segments; determining a background model for the part, the scan data, or both; and determining a bulk porosity based on a difference between the scan data and the background model.

摘要: A coring tool includes a coring bit to cut and detach a core sample from a subsurface formation formed in a borehole. The coring tool includes a pressure vessel that includes a core chamber to store the core sample at a pressure and a piston positioned adjacent to the core chamber. The pressure vessel includes a chamber adjacent to the piston and a gas reservoir to store a gas that expands as the gas is moved to a surface of the borehole. The pressure vessel includes a valve coupled to an inlet of the chamber and an outlet of the gas reservoir, wherein the gas is to flow into the chamber when the valve is open to move the piston to cause an increase in the pressure of the core chamber.

摘要: A system for computed tomography inspection can include a stage, a stationary radiation source, a stationary radiation detector, and a controller. The stage can secure a target thereon and rotate about a rotation axis. The radiation source can emit a beam of penetrating radiation from a focal point that is directed upon a portion of the target. The radiation detector can include a sensing face configured to acquire measurements of radiation beam intensity incident thereon as a function of position. The controller can command the stage to translate from a first position to a second position in a direction transverse to a central axis of the radiation beam. A magnification of the target at the first and second positions can be approximately equal. The stage does not translate transverse to the central axis of the radiation beam during measurement of the radiation beam intensity by the detector.

摘要: Overlapping pores in a multiscale model of heterogeneous core formation contributes errors during flow simulations. A scale-coupled multiscale modeling that corrects for contributions of overlapping pores may be used to determine capillary pressure and relative permeability of the heterogenous core formation more accurately. The effects of overlapping pores may be removed by converting pores that have a certain radius or are filled with certain fluids into solid regions. The effects of overlapping pores may also be removed by running flow simulations on a modified model and correcting various fluid properties of the core formation with the results.
