Abstract: A system includes one or more server hardware computing devices communicatively coupled to a network. The one or more server hardware computing devices include one or more processors and memory storing specific computer-executable instructions that, when executed by the one or more processors, cause the system to receive a first request to calculate a trust score for a user associated with a user account of an online proctored examination platform. The trust score represents results of a risk analysis of the user. The instructions cause the system to obtain internal data of the online proctored examination platform, the internal data describing usage of the online proctored examination platform by the user, perform the risk analysis using at least the internal data to produce the trust score, associate the trust score with the user account, and perform an action based on the trust score.

In one example, a method may include flowing air from an intake of an engine to one or more emission control devices via an air injection system while operating a turbocharger via an electric motor to maintain a desired airflow to the engine in response to an emission control device heating condition. In this way, fresh air is provided to the one or more emission control devices without degrading engine performance or increasing engine speed.

Abstract: A low-volume non-rising stem gate valve comprising a hollow stem, planetary roller screw and anti-rotation rods. The anti-rotation rods isolate the torque force and maintain the alignment of the planetary roller screw with the stem and the screw shaft, thus reducing the amount of material necessary to support ordinary operational forces.

Abstract: A rocker arm for a type III valve train assembly for an internal combustion engine includes: a roller follower for following a cam in use; a roller axle about which the roller follower rotates in use; a biasing means holder, the biasing means holder being connected to the roller axle for sliding movement relative to the roller axle over a fixed distance, the biasing means holder contacting a reaction component in use; and a biasing means arranged to bias the biasing means holder away from the roller axle. The rocker arm is arranged such that, in use, sliding movement of the biasing means holder relative to the roller axle when the biasing means holder contacts the reaction component when a lift profile of the cam engages the roller follower causes the biasing means to compress and thereby to urge the roller follower into contact with the cam.

Abstract: Systems and methods may utilize a predictive analysis model to analyze a contract or other document. A system may parse a document and/or a repository of information associated with the document. The system may identify one or more terms in the document and corresponding terms in the repository. The system may determine a difference parameter between a first term extracted from the document and a second term extracted from the repository. The system may determine whether the difference between the first term and the second term, represented by the difference parameter, is likely to be acceptable to the user using a predictive analysis model. The system may report a validation parameter indicating a level of acceptability associated with the difference. User feedback on the accuracy of the predictive analysis model is used to train, modify, and improve the predictive analysis model.

Abstract: Message content is scaled to support rich messaging. Devices and associated messaging systems can support various levels of content richness or fidelity. Message content scaling is employed to ensure sharing of content in as rich a manner as possible given limitations associated with various messaging systems, among other things. Messages can be scaled down or degraded, for instance where communicating devices do not support high fidelity content being transmitted. Alternatively, messages can be scaled up or enriched in cases, where low fidelity content is transmitted to a device supporting richer content, for example.
