Abstract: A time series forecasting service system is disclosed. The system identifies a set of cross-validation parameters to be used for cross-validating a model to be used for generating a requested forecast. The requested forecast includes a time series dataset and a forecast horizon identifying a number of time steps for which a forecast is to be made using the time series dataset. The system identifies an objective function to be minimized for determining optimal values for the set of cross-validation parameters and identifies constraints for the cross-validation parameters. The system uses an optimization technique to determine the optimal values for the cross-validation parameters. The optimization technique performs processing that determines the optimal values by minimizing the objective function while satisfying the set of constraints. The system uses the optimal values for the cross-validation parameters to perform cross-validation of the model to be used for making the requested forecast.

Abstract: Techniques for providing request throttling using proportional, integral, and exponential smoothing algorithms are disclosed. A distributed computing system can include a throttler engine that receives a plurality of requests targeting a software component within the distributed computing system. The throttler engine can aggregate the requests into a queue based on a time window. The throttler engine can determine a received request rate and a request rate limit for the software component and then compute a throttled request rate. The throttled request rate can include correction terms derived from proportional and integral computations and a correction term obtained from an exponential smoothing algorithm. The throttler engine can then provide throttled requests from the queue to the software component.

Abstract: An improved process and catalyst composition for cracking hydrocarbons in a fluidized cracking process are disclosed. The process employs circulating inventory of a regenerated cracking having a minimal carbon content. The regenerated catalyst comprises a catalyst/additive composition which contains a pentasil zeolite, iron oxide, and a phosphorous compound. In accordance with the present disclosure, the catalyst/additive contains controlled amounts of iron oxide which is maintained in an oxidized state by maintaining low amounts of carbon on the regenerated catalyst inventory. In this manner it was discovered that the catalyst composition greatly enhances the production and selectivity of light hydrocarbons, such as propylene.

Abstract: A method and system for replicating file system entities in a manner that preserves block-level access and file system efficiency mechanisms such as deduplication are disclosed. In an embodiment, a replication engine receives a stream of file system entities that include a file system inodes and file system data blocks. The replication engine generates object-based storage (OBS) objects based on data and reference information specified by the file system entities. As part of generating the OBS objects, the replication engine generates at least one inode file object that associates file block numbers of a file system inode file and the inode numbers. The replication engine uses inode information to generate reference objects that logically associate file block numbers with data block numbers in per inode manner. The replication engine further generates data objects that contains the file system data blocks and that associates the data blocks with corresponding data block numbers.

Abstract: Technology to respond to a termination reason of an accounting record via an improved charging component is disclosed. The disclosed subject matter can be backwards compatible to support responding to a conventional SIP ‘BYE’ method and a conventional SIP ‘CANCEL’ method. Additionally, the disclosed subject matter can respond to other SIP methods, empty reason-headers, etc. In an aspect, a reason-header can be forced into an accounting record based on received session termination information. In an embodiment, the reason-header can be determined to satisfy a rule related to acceptable reason-headers. Where the rule is determined to be unsatisfied, a query can be generated toward a device that supported the now terminated communication, wherein a response to the query can comprise another reason-header that can be determined to satisfy the rule. The accounting record can be updated based on the other reason-header and employed in generating a charging data record that can alter corresponding billing.

Abstract: A control plane entity can perform validation checks to confirm the validity of a device identifier, for example, an international mobile equipment identity (IMEI), received from a user equipment (UE) during registration of the UE with a communication network. In one aspect, the control plane entity can verify that the IMEI conforms to a defined format; for example, the IMEI is fifteen digits long, does not comprise alphabets and/or symbols, and/or comprises a valid type allocation code (TAC) of eight decimal digits, etc. The validation of the IMEI can reduce errors in billing that can otherwise result in revenue loss for the service provider.
