Abstract: An apparatus comprises a storage configured to store data items associated with error correction codes (ECCs); data retrieval circuitry responsive to a data retrieval request specifying a retrieval address to retrieve a retrieved data item and an associated ECC from a storage location corresponding to the retrieval address; and ECC decoding circuitry to generate a syndrome value by performing an ECC decoding operation on a decoding input value comprising data bits of the retrieved data item, code bits of the associated ECC, and address bits of the retrieval address, and to determine based on the syndrome value whether an error condition has occurred. Each bit of the syndrome value depends on a different combination of bits of the decoding input value. For each data bit of the decoding input value, an odd number of bits of the syndrome value depend on that data bit. For each address bit of the decoding input value, an even number of bits of the syndrome value depend on that address bit.

Abstract: Methods, systems, and computer-readable media for compliance lifecycle management for cloud-based resources are disclosed. A selection is received of a compliance pack from a plurality of compliance packs. The compliance pack comprises a plurality of rules associated with policy compliance. The compliance pack is selected from the plurality of compliance packs via a user interface. The selection is associated with one or more resources hosted in one or more provider networks. An evaluation is performed of compliance of the one or more resources with respect to the plurality of rules of the compliance pack. Data describing the evaluation is generated and displayed.

Abstract: Described herein are nanoribbon-based transistors with a highly uniform oxide layer around semiconductor nanoribbon channels, and a high-pressure steam process for growth the oxide layer. The high-pressure steam process is a self-limiting process that results in a more uniform oxide than standard deposition or implantation methods. The uniformity enables greater control over oxide thickness, with improved breakdown voltages and drive currents.

Abstract: A system, method, and computer-readable medium for proving feedback on database instructions, identifying, for example, existing patterns and providing suggested replacement instructions. This may have the effect of improving the efficiency of instructions used to create and/or manipulate databases. According to some aspects, these and other benefits may be achieved by parsing received instructions into an organizational structure, traversing the organizational structure for known patterns, and suggesting replacement patterns. In implementation, this may be effected by receiving one or more sets of known patterns and corresponding replacement patterns, parsing received instructions, comparing the known patterns with the parsed instructions, and providing suggested replacement patterns based on one or more known patterns matching the parsed instructions. A benefit of may include reducing Cartesian products during the merging of tables.

Abstract: An apparatus is provided having a memory device and associated access control circuitry, and an additional memory device and associated additional access control circuitry. Redundant data generation circuitry generates, for a given block of data having an associated given memory address, an associated block of redundant data for use in an error detection process. The access control circuitry is arranged to store, at a location in the memory device determined from the given memory address, at least a portion of the given block of data and a first copy of the associated block of redundant data, and the additional access control circuitry is arranged to store, at a location in the additional memory device determined from the given memory address, any remaining portion of the given block of data not stored in the memory device and a second copy of the associated block of redundant data.

Abstract: Techniques are described herein for managing transactions between data consumers and data providers using a blockchain. In some embodiments, a blockchain network receive smart contracts that govern access rights to data sets provided by blockchain members and smart contracts that execute blockchain transactions based on the usage of data sets. When a data set is provided to a blockchain member through the blockchain network, usage of the data set may be tracked. Responsive to detecting usage of the data set, one or more smart contracts may execute one or more blockchain transactions within the blockchain network.

Abstract: Techniques are described through which groups of individuals and/or other entities may interface with a data cloud blockchain network and/or cloud-based platform to collectively share data in a secure, controlled manner. Decentralized groups that are connected to the data cloud network may be registered and listed in a searchable directory. Entities that are interested in accessing data associated with a group may browse the directory, execute smart contracts within a blockchain, and track online content interactions of a group in a manner that does not compromise the anonymity of individual group members. Data usage and performance metrics may be tracked on the blockchain network using data cloud services, and the metrics may be written to distributed ledgers within the blockchain network. Smart contracts and chaincode within the network may initiate blockchain transactions based on performance metrics and/or other aspects associated with accessing information about a group.

Abstract: A device that uses a motor may quickly and safely stop the motor using a rapid braking system. For example, the device may stop to avoid collision with an object, upon determining a failure of an internal component, upon receipt of a command, and so forth. Responsive to a signal to stop, the motor is disconnected from the battery. A braking circuit is activated that dissipates, in a controlled fashion, power produced by continuing motion of the motor. When the voltage produced by the motor's continuing motion drops below a threshold, a stop circuit shorts the terminals of the motor, causing the motor to resist further rotation. When the stop condition no longer applies the signal to stop is removed resulting in the motor being reconnected to the battery, the braking circuit being deactivated, the stop circuit opens the short between the terminals of the motor, and normal operation resumes.

Abstract: Direct steam injection (DSI) heating techniques can use a heater to heat a process stream in bitumen froth treatment. The DSI heater can include a diffuser with multiple side-by-side rows of outlets perpendicular to a longitudinal axis of the diffuser, and a piston plug that moves axially within the diffuser to selectively cover rows of outlets to vary steam injection. The piston plug has first and second annular seals and is moved between different axial positions in a stepwise fashion such that when one or more rows of outlets are completely covered, the first annular seal is located in between adjacent rows and the second annular seal abuts against the diffuser to inhibit passage of steam so as to prevent cavitation. The DSI heater can include various other features, such as particular seal unit constructions and diffuser outlet configurations.
