Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for providing a secure development environment for developing computer models by utilizing an exploration environment in conjunction with a production environment. In particular, the disclosed systems provide a method for a client account to develop machine learning models securely and efficiently (e.g., access, generate, train, and activate) by utilizing a scalable exploration environment isolated from a production environment. Further, the disclosed systems can provide a system for the client account to utilize to convert the exploration model to a production model and activate the production model within the production environment. In this way, the disclosed systems provide a separation between the exploration environment and the production environment when testing models and thus constrain the impact of testing models to the production environment.

Abstract: Hydrocarbon-containing fluids are provided for use during solvent-assisted hydroprocessing of pyrolysis tar, such as steam cracker tar. The hydrocarbon-containing fluids can be used at any convenient time, such as during start-up of a pyrolysis process when recycled liquid pyrolysis product is not available; when the amount of liquid pyrolysis product available for recycle is not sufficient to maintain desired hydroprocessing conditions; and/or when the changes to the quality of the liquid pyrolysis product reduce the suitability of the recycle stream for use as a utility fluid.

Abstract: According to one aspect, an autonomous vehicle that includes a lidar unit collects lidar point cloud data that includes false returns or false positives, and characterizes the data associated with the false returns or false positives as drivable or not drivable. The false returns or false positives may be phantom points that are not associated with actual objects which may pose collision risks. Analyzing lidar point cloud data to characterize false returns or false positives as either drivable or not drivable enables an autonomous vehicle to operate efficiently by not having to avoid non-existent collision risks. False positives may be indicated when a wet or icy road surface acts as a mirror which reflects objects, and when precipitation such as raindrops appear as objects. Characterizing such false positives as drivable facilitates the efficient operation of an autonomous vehicle as the autonomous vehicle may drive over a mirror and/or through precipitation.

In another embodiment, a hydrocarbon mixture is provided. The hydrocarbon mixture includes a mid-cut composition.

Abstract: Processes for improving hydrocarbon feedstock compatibility are provided. More specifically, a process for preparing a liquid hydrocarbon product includes heat soaking a tar stream to produce a reduced reactivity tar and blending the reduced reactivity tar with a utility fluid comprising recycle solvent to produce a lower viscosity, reduced reactivity tar. The process also includes hydroprocessing the lower viscosity, reduced reactivity tar at a temperature of greater than 350° C. to produce a total liquids product containing the liquid hydrocarbon product and the recycle solvent. The process further includes separating the recycle solvent from the total liquids product, where the recycle solvent has the SBN of greater than 110, and flowing the recycle solvent to the reduced reactivity tar for blending to produce the lower viscosity, reduced reactivity tar.

Abstract: An apparatus measures a speaker impedance. A DAC converts a known digital input signal to an audio frequency first analog voltage signal. Resistors with known resistance attenuate the first analog voltage signal to generate a current. The known resistance effectively determines the current because the known resistance is high relative to the speaker impedance. The current is sourced into the speaker to generate a second analog voltage signal. The known resistance is sufficiently high to cause the second analog voltage signal to be inaudible as transduced by the speaker. An amplifier amplifies the second analog voltage signal with a known gain to generate a third analog voltage signal. An ADC converts the third analog voltage signal to a digital output signal. A processing element calculates the impedance of the speaker proportional to the digital output signal based on the known digital input signal, the known resistance, and the known gain.
