  • Publication number: 20230018159
    Abstract: Methods and systems for generating a computer program for a governance, risk, compliance (GRC) system are described. In an example, a processor may detect a change among a plurality of objects in the GRC system. The processor may generate a snapshot of the plurality of objects in response to the detected change. The snapshot may include the detected change among the plurality of objects. The processor may train a machine learning model using the snapshot. The trained machine learning model may indicate relationships among a set of related objects, where the related objects may be among the plurality of objects. The processor may generate a computer program based on the trained machine learning model. The computer program may include a set of instructions for setting a field value of an object among the set of related objects.

  • Publication number: 20170349546
    Abstract: A binding pair for chromatographic separation or purification of a molecule of interest, where one binding member of the pair is an isomerizable organic molecule and the other binding member of the pair is an isomer-specific affinity agent bound to a molecule of interest. The binding pair associates and disassociates upon exposure to a binding agent, such as using light, decreased intensity of light, darkness, heat, stress, ions, an isomerizable affinity agent, change in pH, or a combination thereof.

  • Patent number: 8255171
    Abstract: A method for determining when a ceramic component on a platform should be replaced. The method includes determining parameters for the ceramic component, the parameters include empirically determined a critical stress intensity factor, and a geometry factor for the ceramic component. The method also includes determining a relationship between platform operational parameters to the generation of stress at the surface of interest of the ceramic component, determining an initial crack size of a crack within the ceramic component at installation, tracking operational parameters of the platform throughout a course of usage of the ceramic component, calculating the corresponding stress at the crack location due to the tracked operational parameters, and calculating a numerical solution that illustrates a crack growth rate velocity and tracks a size of the crack over time. The ceramic component is replaced based on the crack growth rate velocity and the size of the crack.

  • Patent number: 6856740
    Abstract: An optical fiber having an elevated threshold for stimulated Brillouin scattering is provided. The optical fiber includes a core and a cladding surrounding the core with both the core and the cladding designed to guide optical waves through the core while anti-guiding acoustic waves. Moreover, the optical fiber includes other features to alter the mode profile of the acoustic waves and/or to further promote their lateral radiation. For example, the optical fiber can include an irregular coating to alter the mode profile of the acoustic waves. In another example, the optical fiber can include a quarter wave layer surrounding the cladding to promote the lateral radiation of the acoustic waves. In order to further alter the mode profile of the acoustic waves, the cladding can also have a lateral thickness that varies irregularly in a lengthwise direction.

  • Publication number: 20020118935
    Abstract: An optical fiber having an elevated threshold for stimulated Brillouin scattering is provided. The optical fiber includes a core and a cladding surrounding the core with both the core and the cladding designed to guide optical waves through the core while anti-guiding acoustic waves. Moreover, the optical fiber includes other features to alter the mode profile of the acoustic waves and/or to further promote the lateral radiation of at least some of the acoustic waves. For example, the optical fiber can include an irregular coating surrounding the cladding that varies in a lengthwise direction in order to alter the mode profile of the acoustic waves. In addition to or instead of the irregular coating, the optical fiber can include a quarter wave layer surrounding the cladding to promote the lateral radiation of the acoustic waves away from the core and cladding.

  • Patent number: 6369897
    Abstract: A fiber optic receiving antenna is provided that permits the reception of an incident electric field without re-radiating any portion of the incident power. The fiber optic receiving antenna includes a master oscillator for generating a reference signal and a fiber optic interferometer having first and second arms formed of respective optical fibers for receiving the reference signal. The respective electrooptic activity of the optical fibers that form the first and second arms differ such that the signals propagating along the first and second optical fibers will be modulated differently in response to an incident electric field. The fiber optic interferometer also includes a coupler for combining the signals that have propagated along the first and second arms and been differently modulated by the incident electric field.

  • Patent number: 5432257
    Abstract: A process is disclosed for preparing a polysulfide polymer using a heavy ends waste generated in chlorinated hydrocarbon production. The process involves first pretreating the heavy ends waste by an enriching process to form an enriched heavy ends waste with an ethylene dichloride content less than 10% by weight. The enriched heavy ends waste is then reacted with alkaline polysulfide within a temperature range of 50.degree. C. to 150.degree. C. to form a polysulfide polymer.
