  • Publication number: 20180031430
    Abstract: Collecting roll data associated with a sensing and mating rolls that form a nip uses first and second pluralities of sensors. Each sensor of the first plurality has a corresponding sensor in the second plurality which is associated with a same respective axial location on the sensing roll but is spaced-apart circumferentially. The sensors are located at axially spaced-apart locations of the sensing roll and generate either a first or second respective signal when entering the nip. Upon receiving a generated signal, a determination is made about which sensor generated the received signal and the membership of that sensor in one of the pluralities. Based upon a rotational position of the mating roll, a determination is made of which tracking segment associated with the mating roll enters the region of the nip concurrently with the signal to store the signal using the determined one tracking segment and the determined membership.

  • Publication number: 20180031453
    Abstract: The present disclosure describes a method of treating a sample comprising cells with a process of partial lysing. Cells are exposed to a process such as bead beating that lyses some cells in the mixture. The process generates a resultant sample mixture that is suitable for both cell morphology screening and genetic screening. A first portion of the partially lysed sample can be mounted on a slide and observed for atypical cells and cytologic abnormalities. A second portion of the partially lysed sample can be screened for genetic markers known to correlate with a risk of cervical cancer. The method is particularly useful for cervical screening, where a combination of cytology and genetic screening present a more complete picture of cervical health. The disclosed method streamlines the diagnostic process for protocols that require both types of assays, without compromising screening accuracy.

    Abstract: The present method for testing the bonding strength of rock bolt-grout-surrounding rock comprises the following steps: step 1, fabricating the simulative body of a rock bolt provided with a first surface, wherein the concave-convex characteristic of the first surface is consistent with the surface appearance of a rock bolt, and the first surface is a plane; step 2, pouring a grout layer for simulating the grout material on the first surface of the simulative body of the rock bolt; step 3, pouring a surrounding rock layer for simulating the surrounding rock material on the solidified grout layer, wherein the simulative body of the rock bolt, the grout layer and the surrounding rock layer form a simulative anchoring body; and step 4, performing a shear test along the simulative stress direction of the simulative anchoring body to obtain mechanical parameters reflecting the bonding strength of the anchoring body.

  • Publication number: 20180031459
    Abstract: Methods for calibration of non-contact velocity measurements and systems for implementing the same are described. Generally, the method comprises inducing a shock wave into a sample at a stress intensity that varies across the sample's elastic limit, which corresponds to the elastic-plastic state transition of the sample. That transition state may be at the sample's Hugoniot elastic limit. The velocity of the sample is measured using a non-contact velocity measurement instrument such as a velocimeter. The measurement may be compared to a predicted velocity or a velocity measurement made by another system to determine calibration parameters.

  • Publication number: 20180031463
    Abstract: A thin-layer chromatography device can be used to determine or select a surfactant solution for use during hydrocarbon-fluid production operations. The thin-layer chromatography device can include a chamber that can receive a surfactant solution that includes a surfactant and a fluid. The thin-layer chromatography device can also include a substrate that can be coated with a layer of adsorbent material to form a thin-layer substrate and a hydrocarbon fluid can be disposed on the thin-layer substrate. The thin-layer substrate, along with the hydrocarbon fluid, can be positioned within the chamber to determine a mobility index of the hydrocarbon fluid when the hydrocarbon fluid contacts the surfactant solution. The mobility index can indicate an eluting capability of the surfactant solution with respect to the hydrocarbon fluid and can be used to select the surfactant solution to be injected into a wellbore that includes the hydrocarbon fluid to enhance hydrocarbon-fluid production operations.

  • Publication number: 20180031470
    Abstract: Metrology scatterometry targets, optical systems and corresponding metrology tools and measurement methods are provided. Targets and/or optical systems are designed to enhance first order diffraction signals with respect to a zeroth order diffraction signal from the scatterometry target by creating a phase shift of 180° between zeroth order diffraction signals upon illumination of the scatterometry targets. For example, the targets may be designed to respond to polarized illumination by producing a first phase shift between zeroth order diffraction signals upon illumination thereof and optical systems may be designed to illuminate the target by polarized illumination and to analyze a resulting diffraction signal to yield a second phase shift between zeroth order diffraction signals upon illumination thereof. The phase shifts add up to 180° to cancel out the zeroth order diffraction signals, with either phase shift being between 0 and 180°.
