Abstract: Disclosed are various embodiments for automated parallelization of logical rules. A first computing device can determine individual dependencies between individual ones of a plurality of objects stored in the memory, each of the objects comprising a node representing a logical rule and at least one edge representing variable linked to the logical rule. The first computing device can then divide the plurality of objects into a plurality of groups of objects based at least in part on the individual dependencies between the individual ones of the objects, wherein individual objects within individual ones of the groups of objects are independent of individual objects within other ones of the groups of objects. Subsequently, the first computing device can assign individual ones of the groups of objects to individual computing devices for execution in parallel, the individual computing devices being separate from the first computing device.

Abstract: One or more visual descriptors for a particular Point of Interest (POI) are extracted from a corpus of User-Generated Content (UGC), wherein the corpus of UGC comprises a plurality of textual content items descriptive of the particular POI. Based on the one or more visual descriptors, a machine-learned generative vision model is used to generate a query image that depicts the particular POI. A visual similarity is determined between the query image and each of a plurality of candidate images of a corpus of visual UGC that depicts the particular POI. A representation image is selected from the plurality of candidate images to represent the particular POI based on the visual similarity between the representation image and the query image.

Abstract: The present disclosure provides computer-implemented methods, systems, and devices for analyzing visual content to assign one or more subjective labels. A computing device transmits a piece of visual content and a subjective attribute to a plurality of computing systems. The computing system receives operator feedback indicative of ratings from the operators, each rating indicative of a perceived similarity between the visual content and the subjective attribute. The computing system determines that a similarity between the ratings is less than a threshold similarity. Responsive to determining that a similarity between the ratings is less than a threshold similarity, the computing system generates pseudo-labels associated with the subjective attribute, wherein the one or more pseudo-labels comprise additional description of the subjective attribute. The computing system transmits the one or more pseudo-labels and a piece of visual content to a second plurality of computing systems.

Abstract: A self contained, 1 V to 550 V powered UVC device used to sterilize spaces like vehicle cabins or indoor rooms or spaces, while providing the ability to monitor both pre and post sterilization. While operating, the device would collect, on suitable gathering/testing media, both air that has been sterilized, and unsterilized air that passes through the media, allowing the media to be tested for the presence of both active pathogens that have not yet been killed from the device, as well as killed pathogens in the sterilized area. The UVC and media components may be integrated into one unit, or be powered and used both in combination, or as separate devices performing the sterilization and the sampling media. At the termination of UVC sterilization, additional different media has the now sterilized cabin or room air circulated through it, and with further media testing and evaluation, the efficiency/effectiveness of the sterilization process can be audited, and system operators can be advised.

Abstract: The present disclosure is directed to processing iron-containing feedstocks using oxalic acid to cost-effectively and cleanly transform low-cost iron feedstocks into iron-containing products (e.g., metallic iron and/or iron oxide) of high purity. In general, the methods of production using the systems described herein may include leaching low-purity iron feedstocks using a lixiviant including oxalic acid and an iron-complexing additive. The iron-complexing additive may suppress formation of iron (II) oxalate crystals and iron (III) oxalate crystals as leaching of a low-purity iron feedstock is carried out using oxalic acid, thus improving process kinetics and increasing the amount of iron that goes into solution during the leaching operation and ultimately recovered as a high-purity iron-containing product (e.g., metallic iron and/or iron oxide).

Abstract: A metal detector is used with a receptacle to receive refuse. The metal detector includes a body defining an opening, a controller, and a coil wound around the opening. The controller detects changes to a magnetic field generated by the coil when an object comprised of a metallic material that is located proximate the coil interacts with the magnetic field and induces a voltage within the coil. A capacitive sensor is mounted to the body and communicates with the controller. The controller is configured to detect the object located within the opening based on a proximity signal produced by the capacitive sensor when the object interacts with an electrical field of the capacitive sensor. When the controller determines that the object is comprised of a metallic material and disposed within the opening based on the induced voltage and the proximity signal, the metal detector correspondingly produces an alarm.

Abstract: Methods and systems of the present disclosure are generally directed to switching operation of one or more electrochemical cells of an electrowinning plant between a charge mode and a discharge mode. In the charge mode, the one or more electrochemical cells may reduce metal from an oxidized state to a zero valence state with a first electric current applied across the one or more electrochemical cells. In the discharge mode, the one or more electrochemical cells may oxidize at least some of the metal from the zero valence state to the oxidized state to generate a second electric current, oppositely charged relative to the first electric current, to generate electricity (e.g., for delivery to the grid). Operation of the one or more electrochemical cells of the electrowinning plant may be selectively changed between the charge mode and the discharge mode based on, for example, availability/cost of electricity from the grid.

Abstract: An image processing system receives a digital image and analyzes the digital image to determine a resolution limit, referred to herein as “feature resolution,” for measuring a metric for features of the image within an acceptable margin of error. Specifically, the system segments a digital image and calculates the error associated with the segmented data when features within a certain range a measured metric (e.g., size range) are removed from the segmented data. This analysis can be repeatedly performed with different cutoff values for the metric until at least a threshold amount of error is reached, thereby indicating a resolution limit at the boundary of an acceptable amount of error.
