Abstract: The present disclosure provides systems, methods, devices, and computer program products for cache eviction enforcement and multi-tenant distributed cache architectures and operations. Systems, methods, devices, and computer program products may access a slab of a multi-tenant caching system, perform an eviction review by sequentially reaping through the slab, based on the class size, flag a first cache item by the eviction review based on a header of the first cache item, wherein the header comprises a prefix indicative of an expiry time, confirm expiration of the first cache item via a lock and lookup operation, and evict the first cache item from the slab. Significant optimization and efficiency benefits may be realized through the slab organization, cache architectures, and operations discussed herein.

Abstract: A method for determining improved control parameters of a number of wind turbines of a wind park is provided. The method considers the impact of individual turbine manufacturing tolerances on the turbine performance, thereby avoiding under-utilization of those wind turbines. The method includes the steps of: receiving, by an interface, one or more actual manufacturing tolerances of characteristic values for each of the number of wind turbines; determining, by a processing unit, for each of the number of wind turbines a power versus wind speed map which is calculated from a given turbine model with the one or more actual manufacturing tolerances of the respective wind turbines as input parameters; and deriving, by the processing unit, the control parameters for each of the number of wind turbines from their associated power versus wind speed map.

Abstract: Examples provide an item storage cart for verifying correct item placement into containers on the item storage cart. A cart manager component outputs planogram data identifying a location of a selected item. Weight data generated by one or more weight sensors associated with the set of item storage containers is analyzed to verify whether a correct item is placed in a given storage container on the cart and/or verify a selected item is placed into a correct storage container. The cart manager component determines if an unselected item is removed from a storage container and/or if an unselected item is added to a storage container. A notification is output if an incorrect item is added to a cart, an incorrect item is removed from the cart, an item is added to the wrong container or removed from the wrong container.

Abstract: Systems and techniques for dynamic color adjustment in augmented reality are described herein. An image of a user may be obtained from an imaging sensor.

Abstract: The present invention relates to a method of monitoring oscillations that are liable to interact in an electrical power network, in dependence on measurement of AC waveforms in the electrical power network. The method comprises receiving first waveform data corresponding to an electrical quantity in each phase of at least two phases of three-phase AC waveforms at a location in the electrical power network. The method further comprises applying a transformation to the first waveform data to provide therefrom second waveform data corresponding to an electrical quantity at the location in a single phase representation, the second waveform data depending on the at least two phases.

Abstract: A coax server acts as a proxy between a coax transmission infrastructure and an Internet Protocol (IP) transmission infrastructure. An incoming request is received from a particular one of a plurality of coax client devices on the coax infrastructure. A request for specific media content is transmitted to a media-on-demand server in response to receiving the incoming request. A media stream is received over the IP infrastructure from the media-on-demand server, the media stream corresponding to the specific media content, and the coax server allocates a coax channel of sufficient bandwidth on the coax infrastructure and transmits the media stream on the coax channel utilizing the RF modulation scheme. A pointer indicating the coax channel on which the media stream is being transmitted is sent to the particular coax client device. The coax channel is unknown to other of the coax client devices besides the particular coax client device.
