Abstract: A computer implemented method includes obtaining, by the computer, assay data for a feedstock containing measurements for one or more aspects of the first feedstock, a first equipment model containing properties of processing units, and processing conditions containing one or more variables by which the first feedstock will be processed by the processing units. The computer determines a corrosion amount of the processing units using the processing conditions, the properties of the processing units contained in the equipment model, and the assay data for the feedstock, and stores/displays the corrosion amount of the processing units. A safety warning may be displayed, and the feedstock rejected if the corrosion amount exceeds a predetermined safety level for one or more of the processing units.

Abstract: Techniques and tools for performing fading compensation in video processing applications are described. For example, during encoding, a video encoder performs fading compensation using fading parameters comprising a scaling parameter and a shifting parameter on one or more reference images. During decoding, a video decoder performs corresponding fading compensation on the one or more reference images.

Abstract: Described tools and techniques relate to signaling for DC coefficients at small quantization step sizes. The techniques and tools can be used in combination or independently. For example, a tool such as a video encoder or decoder processes a VLC that indicates a DC differential for a DC coefficient, a FLC that indicates a value refinement for the DC differential, and a third code that indicates the sign for the DC differential. Even with the small quantization step sizes, the tool uses a VLC table with DC differentials for DC coefficients above the small quantization step sizes. The FLCs for DC differentials have lengths that vary depending on quantization step size.

Abstract: Provided are methods and systems for transition between a current cloud-based code environment and an updated cloud-based code environment. A method for transition between a current cloud-based code environment and an updated cloud-based code may commence with generating a steering policy. The steering policy may include a set of rules to guide steering decisions between a current cloud-based code environment and an updated cloud-based code environment. The method may further include sending the steering policy to a steering server. The steering server may make steering decisions to steer, based on the steering policy, service requests between the current cloud-based code environment and the updated cloud-based code environment. The method may continue with receiving feedback concerning actual steering decisions made by the steering server. The method may further include automatically adjusting the steering policy in response to the feedback.

Abstract: Various embodiments, methods, and systems for erasure coding with overlapped local reconstruction codes, are provided. An erasure coding scheme can be defined based on Overlapped Local Reconstruction Codes (OLRC) that achieve high storage efficiency by providing fault tolerance properties that optimize reconstruction for common cases of failures while maintaining the reconstruction costs for uncommon case of failures. In operation, a data chunk is divided into data fragments. The data fragments correspond to zones. A plurality of parity fragments is computed using the data fragments. A parity fragment is computed using a subset of the data fragments. The plurality of parity fragments are assigned to the zones comprising the data fragments, where the data fragments and the plurality of parity fragments define overlapped local construction codes having a plurality of local groups. An unavailable data fragment is recoverable from at least two local groups from the plurality of local groups.

Abstract: A digital media encoder/decoder uses a flexible quantization technique that provides the ability to vary quantization along various dimensions of the encoded digital media data, including spatial, frequency sub bands and color channels. The codec utilizes a signaling scheme to signal various permutations of flexible quantization combinations efficiently for primary usage scenarios. When a choice of quantizer is available, the codec efficiently encodes the current quantizer by defining a subset of quantizers and indexes the current quantizer from the set.

Abstract: A search user input mechanism is displayed on a user interface display. User actuation of the search user input mechanism is detected, to identify a query for a navigation structure that identifies an entry point into an application in the computing system. A path navigation hierarchy is searched to identify the entry point and the path in the navigation hierarchy where the entry point is located. A navigable search result is displayed to the user for actuation, to navigate to the entry point.

Abstract: A video codec uses fractional increments of quantization step size at high bit rates to permit a more continuous variation of quality and/or bit rate as the quantization scale changes. For high bit rate scenarios, the bit stream syntax includes an additional syntax element to specify fractional step increments (e.g., half step) of the normal quantizer scale step sizes.

Abstract: Techniques and tools are described for decoding jointly coded information. For example, a decoder decodes a variable length code [“VLC”] signaled at macroblock level that jointly represents a transform type signal level, transform type, and subblock pattern. The decoder decodes one or more VLCs signaled at block level, each jointly representing a transform type and subblock pattern. The decoder may select between multiple VLC tables for the VLCs signaled macroblock level and/or block level.

Abstract: A system includes a load balancer and storage including a first data structure and a second data structure. Each of the data structures includes a plurality of different weight levels. At least one of the weight levels of the first data structure includes an identifier of a target. At least one of the weight levels of the second data structure includes a map that associates a target identifier with a final weight value. Responsive to receipt of a request and responsive to a target identifier included at a given weight level in the first data structure corresponding to a pointer, the load balancer selects the target identified in the first data structure at the given weight level. Responsive to no target identifiers included at the given weight level in the first data structure, the load balancer selects a target identified in the second data structure at the given weight level. The load balancer forwards the request to the selected target.

Abstract: With adaptive multiple quantization, a video or other digital media codec can adaptively select among multiple quantizers to apply to transform coefficients. The switch in quantizers can be signaled at the sequence level or frame level of the bitstream syntax, or can be implicitly specified in the syntax.

Abstract: Techniques and tools for video coding/decoding with motion resolution switching and sub-block transform coding/decoding are described. For example, a video encoder adaptively switches the resolution of motion estimation and compensation between quarter-pixel and half-pixel resolutions; a corresponding video decoder adaptively switches the resolution of motion compensation between quarter-pixel and half-pixel resolutions. For sub-block transform sizes, for example, a video encoder adaptively switches between 8×8, 8×4, and 4×8 DCTs when encoding 8×8 prediction residual blocks; a corresponding video decoder switches between 8×8, 8×4, and 4×8 inverse DCTs during decoding.
