Abstract: A tip shroud, comprising a plurality of tip shoes encircling a rotor assembly, in a turbine may deform due to thermal gradients experienced during operation of the turbine. Accordingly, a tip shoe is disclosed that utilizes an internal cooling cavity to supply coolant throughout the interior of the tip shoe, as well as to the slash faces of the tip shoe. In addition, features are described that increase the surface area exposed to the coolant, while remaining suitable for additive manufacturing.

Abstract: Pulse-generator-based reciprocal quantum logic (RQL) bias-level sensors are fabricated on an RQL integrated circuit (IC) to sample AC or DC bias values provided to operational RQL circuitry on the RQL IC. The bias-level sensors include pulse generators having strengthened or weakened bias taps (transformer couplings to RQL AC clock resonators or DC bias lines) as compared to bias taps of Josephson transmission lines in the operational RQL circuitry, or Josephson junctions (JJs) with larger or smaller critical currents as compared to JJs in the operational RQL circuitry. Pulse generators with weakened bias taps or larger JJs can have lower limits of their operational ranges placed near an optimal bias point at the centroid of the operating region of the operational RQL circuitry. The bias-level sensors can be staged by relative strength to indicate whether a provided bias value is an improvement when varied over a range.

Abstract: An apparatus for demodulating a frequency-modulated signal comprises a joint frequency-offset & modulation-index estimator, and a signal demodulator. The joint estimator receives data representative of a preamble portion of the signal, modulated with predetermined preamble data. It jointly determines a frequency-offset estimate and a modulation-index estimate by using an optimization process that minimizes a cost function that is a function of the received data and that is parameterised by a frequency-offset parameter and by a modulation-index parameter. The signal demodulator receives data representative of a message portion of the signal, modulated with message data, and uses the frequency-offset estimate to demodulate the message.

Abstract: Systems, methods, and media for generating a virtual gaming environment. Specifically, an instance of a virtual gaming environment is generated and hosted on a server. Responsive to communicatively connecting a first and second user computing devices, a virtual gaming environment is populated with at least a first virtual avatar, a virtual desktop, a second virtual avatar, and a second virtual desktop. It is determined that the first virtual avatar is within a first predetermined distance of the second desktop, and based on this, a resolution at which to render a visual representation of activities being executed by a second user computing device associated with the second desktop is determined. A bandwidth at which the visual representation is renderable in real time at the determined resolution is calculated. The visual representation is transmitted, utilizing the calculated bandwidth, to the first user computing device at the determined resolution.

Abstract: A receiver comprises a matched filter bank, decision logic and a frequency offset estimator. The matched filter bank comprises an input for receiving data representative of a frequency- or phase-modulated signal. The decision logic generates a sequence of demodulated symbol values from outputs of the matched filter bank. The frequency offset estimator determines a first phase value from a first output and a second phase value from a second output of the matched filter bank, the second output being offset from the first by L symbol periods. It also determines a phase adjustment value from an L-symbol subsequence within the sequence of demodulated symbol values, each subsequence value being determined from values output by the matched filter bank between the first and second outputs. It estimates a frequency offset based on the difference between the first phase value plus the phase adjustment value, and the second phase value.

Abstract: The present disclosure provides systems and methods for electronically providing each of a plurality of content distributors with access to a library of content items, facilitating the selection of a combination of the content items, creating a unique set of links for each recipient-distributor combination, and distributing the selected content and unique links via one or more distribution channels to a plurality of recipients. As each link is associated with both a recipient and a distributor, conversion actions stemming from the selection of a link by a recipient are attributed to the proper distributor. Distributors can create content distribution approaches that can be shared with other distributors.

Abstract: In various embodiments, a prediction subsystem automatically predicts a level of network availability of a device network. The prediction subsystem computes a set of predicted attribute values for a set of devices attributes associated with the device network based on a trained recurrent neural network (RNN) and set(s) of past attribute values for the set of device attributes. The prediction subsystem then performs classification operation(s) based on the set of predicted attribute values and one or more machine-learned classification criteria. The result of the classification operation(s) is a network availability data point that predicts a level of network availability of the device network. Preemptive action(s) are subsequently performed on the device network based on the network availability data point. By performing the preemptive action(s), the amount of time during which network availability is below a given level can be substantially reduced compared to prior art, reactive approaches.

Abstract: Systems and methods are directed to a compression scheme for stable universally unique identities in a collaborative editing environment. A client receives edits to a document and immediately creates a local short identity for an element of each edit, whereby the local short identity represents an offset from a base unique identity associated with the client from which a unique identifier assigned to the element is derivable. The local short identity information including the local short identity for each element is transmitted to a server. Subsequently, global short identity information is received from the server from which one or more global short identities that each map to a local short identity of a client of a plurality of clients collaborating on the document can be determined by the client. Each global short identity is a compact identity that is universally unique to the plurality of clients including the client.

Abstract: A co-extruded, dual-texture animal food is provided. The food has a dry outer portion partially surrounding a semi-moist inner portion. The inner portion has a higher or similar moisture content and a softer texture compared to the outer portion which has a lower moisture content and harder texture. The outer portion comprises cereal grain and a legume at about 75-85% of the weight of the outer portion, and an animal-based protein contributing to about 5-10% of the weight or more of the outer portion. The inner portion has animal-derived grease mixed with lactic acid at about 3% by weight of the inner portion, along with at least one meat comprising at least 3% by weight of the inner portion. The composition inhibits moisture transference within and between individual pieces of the food. The food is shelf stable and the inner and outer portions retain their hardness and moisture profiles, post-packaging.

Abstract: Systems and methods that enable hardware memory error tolerant software systems. For instance, the system may comprise a host device that instantiates a kernel agent in response to one or more requests to access hardware memory, determines, by the kernel agent based on the received information, whether the request to access memory will cause access to a corrupt memory location, and skip an operation associated with the corrupt memory location in response to determining that the request will access a corrupt memory location. The systems may also include a system that detects software vulnerabilities to hardware memory errors.
