Abstract: Techniques are described herein for selecting, curating, normalizing, enriching, and synthesizing the results of user experience (UX) tests. In some embodiments, a system receives input defining or modifying a theme schema for classifying results of user experience tests. Responsive to receiving the input, the system trains a themer model based at least in part on example classifications in a training dataset, where the classifications map results to themes within the theme schema. When a new set of results for a user experience test is received, the trained machine learning model may generate a set of predicted themes to classify the test results. The output of the model may be used to render user interfaces and/or trigger other actions directed to optimizing a product's design.

Abstract: Techniques are described herein for selecting, curating, normalizing, enriching, and synthesizing the results of user experience (UX) tests. In some embodiments, a system identifies a set of expectation elements associated with one or more UX tests. An expectation element may specify, using unstructured data that does not conform to a schema, an expectation for a user experience and a respective outcome for the user experience. A themer model may generate predictions that map the respective expectation elements to a theme from a theme schema, which may include a plurality of themes. A selector model may generate selection scores for the expectation elements. The predicted themes and selection scores may be used to render user interfaces and/or trigger other actions directed to optimizing a product's design.

Abstract: Techniques and embodiments are described herein for detecting and mitigating fraudulent activity within user experience (UX) test applications. In some embodiments, a system applies a set of rules and/or machine learning (ML) models to each respondent of an online survey or UX test. Different ML models may be trained to learn domain-specific patterns indicative of fraudulent activity. The system may then select the ML models based on attributes of the UX test and/or respondent. The selected rules and/or ML models may generate a probabilistic score representing a likelihood that the respondent is currently engaging in or will engage in fraudulent activity with respect to a UX test. If the score exceeds a threshold, then the system may take action to mitigate the fraudulent activity, such as triggering the removal of the user from an accepted respondent pool, halting further engagement between the respondent and the UX test, and generating alerts.

Abstract: Techniques are described herein for selecting, curating, normalizing, enriching, and synthesizing the results of user experience tests. In some embodiments, a system identifies a qualitative element within a result set for a user experience test. The system then selects a machine learning model to apply based on one or more attributes associated with the user experience test and generates a predicted visibility, quality, and/or relevance for the qualitative element. Based on the prediction, the system generates a user interface that curates a set of results of the user experience test.

Abstract: A method and apparatus for testing a bond interface is provided. The method comprises directing laser energy at a first surface of a first material connected to a second material by an adhesive at a bond interface. The first surface is opposite the bond interface. A first acoustic impedance of the first material is greater than a second acoustic impedance of the second material. The method also determines whether an inconsistency is present in the bond interface after directing the laser energy.

Abstract: A process for making steel armor products for use, for example as body armor. The steel armor product made has a compound curve and is made from a flat blank of armor steel by high-temperature annealing an armor steel blank to slightly above its austenitizing temperature, then followed by a slow, temperature-controlled cooling it, over-pressing the annealed blank to a first configuration so it springs back to a second configuration approximating the desired product shape when released from the press, and then heat-treating the product back to its austenitizing temperature, quenching it, and tempering it at a low temperature. The tool is conveniently made by lamination, using a series of thin plates of tool steel each cut to produce an approximation of the desired die.

Abstract: A bond inspection system may include a material that reacts to applied activation energy by creating a compression wave, the material positioned adjacent a surface of a structure having a bond to be inspected and shaped in a predetermined pattern, such that reaction of the material causes compression waves to travel through the surface and structure; a source of activation energy capable of directing the activation energy at the material; and a controller programmed to actuate the source of activation energy to direct the activation energy at discrete portions of the predetermined pattern of material in a predetermined sequence selected to create a plurality of the compression waves so that the compression waves reflect from an opposite side of the structure as a plurality of tension waves that combine at substantially the same time at a bondline of the structure to be inspected.

Abstract: A method and apparatus for testing a composite structure. A pulsed laser beam having a number of properties is generated. Each of the number of properties is within a selected range.

Abstract: A method and apparatus for inspecting a structure. In one illustrative embodiment, an apparatus comprises a laser system located outside of an area that includes a region of a structure to be inspected, a mobile platform located within the area to be inspected, and a projection system associated with the mobile platform. The laser system is configured to generate a laser beam. The projection system receives the laser beam and projects the laser beam onto a surface of the region of the structure.

Abstract: A method and apparatus for inspecting a test object with a non-planar feature. A pattern of light is transmitted from a first array of optical fibers associated with a sensor structure onto a surface of the test object at a location of the non-planar feature. The pattern of light is configured to cause sound waves in the test object when the pattern of light encounters the test object. A response to the sound waves is detected using a second array of optical fibers associated with the sensor structure. A determination is made as to whether an inconsistency is present in the test object at the location of the non-planar feature from the response to the sound waves detected using the second array of optical fibers.
