Abstract: A machine trains an artificial intelligence engine to facilitate authentication of a request to verify a user. The machine accesses a reference set of obfuscated geolocations generated from actual geolocations from which a device submitted requests to verify the user. The machine groups the obfuscated geolocations into geographical clusters based on a predetermined cluster radius value and calculates a corresponding representative geolocation for each geographical cluster and a corresponding variance distance from the representative geolocation for each geographical cluster. The machine then generates a reference location score based on the representative geolocations of the geographical clusters and on the variance distances of the geographical clusters. The machine trains an artificial intelligence engine to output that reference location score in response to the reference set being input thereto. The trained artificial intelligence engine may then be provided to one or more devices.

Abstract: Capacitively isolated current-loaded or current-driven charge pump circuits and related methods transfer electrical energy from a primary side to a secondary side over a capacitive isolation boundary, using a controlled current source to charge isolation capacitors with constant current, as opposed to current impulses, while maintaining output voltage within tolerance. The charge pump circuits provide DC-to-DC converters that can be used in isolated power supplies, particularly in low-power applications and in such devices as sensor transmitters that have separate electrical ground planes. The devices and methods transfer electrical energy over an isolated capacitive barrier in a manner that is efficient, inexpensive, and reduces electromagnetic interference (EMI).

Abstract: The present disclosure is related to a computer-implemented method, card processing server, and non-transitory computer readable medium for determining a merchant location using a virtual card, in real-time. A card processing server may receive test transaction data from an acquirer bank of a merchant when a test transaction is initiated through a virtual card provided to the merchant. The card processing server may detect a record of the test transaction in a transaction database, in real-time, using one or more attributes of the virtual card stored in the card processing server and may retrieve signature data from the test transaction data upon detecting the record of the test transaction. Finally, the card processing server determines a transaction source data location of the merchant at which the test transaction was initiated and a registered name of the merchant based on the signature data.

Abstract: A machine detects a request to execute a transaction specified by a first set of user inputs. The machine determines, based on the first set of user inputs that specified the transaction, that the request to execute the transaction is to be verified with a corresponding challenge prompt that is to be generated for the request to execute the transaction. The machine then generates the challenge prompt that corresponds to the request to execute the transaction specified by the first set of user inputs that specified the transaction, and the machine causes presentation of the generated challenge prompt that corresponds to the request to execute the transaction. In response to the presented challenge prompt, the machine may receive a second set of user inputs. Based on the second set of user inputs, the machine then generates an indication of whether the request is verified.

Abstract: In one embodiment, a networking device at an edge of a network enrolls with a controller that supervises operation of the networking device. The networking device sends a publication request to a cloud-based messaging service. The networking device provides, to the cloud-based messaging service, identification information that indicates the controller that supervises operation of the networking device. The networking device receives, from the cloud-based messaging service, authorization to publish messages to the cloud-based messaging service. The cloud-based messaging service uses the identification information to confirm an identity of the networking device with the controller that supervises operation of the networking device. The networking device sends, after receiving authorization to publish messages to the cloud-based messaging service, a message for publication to the cloud-based messaging service. The message comprises data sourced from an endpoint in the network.

In particular, specific electrode designs provide for achieving very high energy densities. Furthermore, the complex behavior of the active materials is used advantageously in a radical electrode balancing design that significantly reduced wasted electrode capacity in either electrode when cycling under realistic conditions of moderate to high discharge rates and/or over a reduced depth of discharge.

Abstract: A device authenticates a request to verify a user. The device accesses a face image that depicts a face of the person and includes a characteristic noise pattern inserted by a camera of the device. The device also accesses a geolocation at which the device captured the face image and inputs the face image and the geolocation into an artificial intelligence engine that outputs a face score, a device score, and a location score. The device next submits the request with the scores to a server machine and obtains an authentication score from the server machine. The device then presents an indication that the request to verify the person is authentic based on a comparison of the obtained authentication score to a threshold authentication score.

Abstract: In energy markets in which bidding process is used to sell energy, it is important that a mechanism for deciding bidding amount is in place. State of the art systems in this domain have the disadvantage that they rely on simulation data, and also they make certain assumptions, and both the factors can affect accuracy of results when the systems are deployed and are expected to handle practical scenarios. The disclosure herein generally relates to energy markets, and, more particularly, to a method and a system for Reinforcement Learning (RL) based model for generating bids. The system trains a RL agent using historical data with respect to competitor bids places and Market Clearing Prices (MCPs). The RL agent then processes real-time inputs and generates bidding recommendations.

The causal diagram is refined in accordance with one or more constraints which supports in making a better and informed decision considering changing dynamics of the plurality of agents.

Abstract: Silicon oxide based materials, including composites with various electrical conductive compositions, are formulated into desirable anodes. The anodes can be effectively combined into lithium ion batteries with high capacity cathode materials. In some formulations, supplemental lithium can be used to stabilize cycling as well as to reduce effects of first cycle irreversible capacity loss. Batteries are described with surprisingly good cycling properties with good specific capacities with respect to both cathode active weights and anode active weights.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for authentication based on physical interaction and characteristic noise patterns. Execution of a requested transaction may be conditioned upon satisfaction of an authentication requirement. For example, the requesting user may be prompted to perform a physical interaction such as a swipe across a screen of a client device. The sensor data includes a characteristic noise pattern caused by manufacturing deviations of the set of sensors that captured the sensor data. The sensor data describing the physical interaction and the characteristic noise pattern are used to determine whether the authentication requirement has been satisfied. For example, the sensor data and characteristic noise pattern are used to determine whether the user that performed the physical interaction is an authorized user. The authentication requirement is satisfied upon determining that the user that performed the physical interaction is an authorized user.
