Abstract: Systems and methods are provided for automatically scoring a response and statistically revaluating whether it can be considered as aberrant. In one embodiment, a constructed response is evaluated via a pre-screening stage and a post-hoc screening stage. The pre-screening stage attempts to determine whether the constructed response is aberrant based on a variety of aberration metrics and criteria. If the constructed response is deemed not to be aberrant, then the post-hoc screening stage attempts to predict a discrepancy between what score an automated scoring system would assigned and what score a human rater would assign to the response. If the discrepancy is sufficiently low, then the constructed response may be scored by an automated scoring engine. On the other hand, if the constructed response failed to pass either of the two stages, then a flag may be raised to indicate that additional human review may be needed.

Abstract: Systems and methods described herein utilize supervised machine learning to generate a model for scoring interview responses. The system may access a training response, which in one embodiment is an audiovisual recording of a person responding to an interview question. The training response may have an assigned human-determined score. The system may extract at least one delivery feature and at least one content feature from the audiovisual recording of the training response, and use the extracted features and the human-determined score to train a response scoring model for scoring interview responses. The response scoring model may be configured based on the training to automatically assign scores to audiovisual recordings of interview responses. The scores for interview responses may be used by interviewers to assess candidates.

Abstract: The use as a sludge controlling additive in a fuel composition for a spark-ignition internal combustion engine or a compression-ignition gasoline internal combustion engine of a combination of: a. a hydrocarbyl-substituted aromatic compound; and b. a polyalkylene amine. The fuel composition may also be used for maintaining oil pathways and/or lubrication in an engine.

Abstract: An additive composition, on use in a fuel in a spark-ignition internal combustion engine, controls the formation of sludge and piston varnish. When used in a direct injection spark-ignition internal combustion engine, particulate emissions and deposit formation on intake valves may also be controlled. When used in a port fuel injection spark-ignition internal combustion engine, the port fuel injection valve deposits may be reduced. The additive composition comprises a polyalkylene amine and a hydrocarbyl-substituted hydroxyaromatic compound. The additive compositions may be present in a fuel composition.

Abstract: The use as a piston varnish controlling additive in a fuel composition for a spark-ignition internal combustion engine or a compression-ignition gasoline internal combustion engine of a combination of: a. a hydrocarbyl-substituted aromatic compound; and b. a polyalkylene amine. The fuel composition may also be used for controlling power output, fuel economy, engine wear, piston ring sticking and blow-by.

Abstract: The use as a particulate emissions and/or a complex poly-aromatic nuclei (CPAN) controlling additive in a fuel composition for a direct-injection spark-ignition internal combustion engine or a compression-ignition gasoline internal combustion engine of a combination of: a. a hydrocarbyl-substituted aromatic compound; and b. a polyalkylene amine.

Abstract: An optical assembly for a system for inspecting or measuring of an object is provided that is configured to move as a unit with a system, as the system is pointed at a target, and eliminates the need for a large scanning (pointing) mirror that is moveable relative to other parts of the system. The optical assembly comprises catadioptric optics configured to fold the optical path of the pointing beam and measurement beam that are being directed through the outlet of the system, to compress the size of the optical assembly.

Abstract: Projection optics for a lithographic projection system is provided that comprises a spatial light modulator (SLM) from which radiation is reflected and directed to a projection lens that projects the radiation to a substrate. The SLM is illuminated by non telecentric off axis illumination (e.g. from laser radiation that has a spectral bandwidth of the order of 1 picometer, and the projection optics is configured for significant reduction (e.g. at least 10× reduction, 20× reduction, or 50× reduction).

Abstract: The use as an intake valve deposit clean-up additive in a fuel composition for a port fuel injection spark-ignition internal combustion engine or a fuel injector deposit clean-up additive in a fuel composition for a direct injection spark-ignition internal combustion engine of a combination of: a. at least one hydrocarbyl-substituted aromatic compound; and b. at least one polyalkylene amine.

Abstract: New and useful optical components are provided, for use in measuring projection lens characteristics of an optical imaging system that images a substrate. The optical components comprise an array of full NA imagers located at the substrate plane, and a relay system for imaging the imagers to a detector that is remote from the substrate.
