Scenario description language
A domain specific language, or Scenario Description Language (SDL), can be used for quickly enumerating scenarios in a simulation for testing and validating interaction of an object (e.g., an autonomous vehicle) within an environment. Scenarios in a simulation are defined using one or more primitives. Primitives are used to define objects to be instantiated (such as body size, position, orientation, velocities, etc.) and/or actions to be performed by the objects in the simulation (such as wait for a period of time, goal positions, follow a particular object, etc.). The SDL enables simple creation of multiple scenarios by combining primitives combinatorially and in some examples, limiting which scenarios are created to those that correspond to combinations that provide meaningful information. Additionally, the SDL allows for instantiation to be agnostic of map features so that a particular scenario can be instantiated automatically over all possible positions within a map. |

Synchronous database replication with asynchronous transaction recovery
A disaster-recovery system contains a networked array of synchronous-to-asynchronous converter (SATC) modules that connect source databases to target backup databases. During backup, the system replicates each source-database transaction through a chain of these SATCs to a corresponding target, storing a local copy of the transaction on each SATC along the way. Each transaction's path between its source-target pair is identified by a set of tracking entries, where each entry identifies one SATC in the path. Every backup transfer between two SATCs in a chain is performed synchronously, such that a successor SATC confirms a successful transfer to a predecessor SATC only after the successor can confirm a successful transfer to the next SATC in the chain. During a subsequent recovery operation, tracking entries are regenerated to locate locally stored transactions that had not time to be fully replicated before a catastrophic failure had occurred. |

Efficient execution of a sequence of SQL operations using runtime partition injection and iterative execution
Execution plans generated for multiple analytic queries incorporate two new kinds of plan operators, a partition creator and partition iterator. The partition creator and partition iterator operate as a pair. A partition creator operator creates partitions of rows and a partitioning descriptor describing the partitions created. A partition iterator iterates through the partitions based on the partitioning descriptor. For each partition, multiple analytic operators are executed serially, one after the other, on the same rows in the partition. According to an embodiment, partitioning is based on a common grouping or subgrouping of the multiple analytic functions or operators. Columns in the grouping or subgrouping may be ignored when executing each of the multiple analytic operators. Forming execution plans that include partition creator and partition iterator in this way is referred to herein as partitioning injection. |

Real-time data validation using lagging replica databases
Systems and methods are disclosed to implement a real-time data validation system that prevents problematic updates from being replicated from a primary database to a replica database. In embodiments, the data validation system injects a time delay into the replication process, so that when an update in a replication stream fails a specified data validation, the data validation system will prevent the update from being applied to the replica. In embodiments, the replication process is halted, a snapshot of the replica database is taken during the halt, and replication to the replica is resumed. Accordingly, if the problematic update is later confirmed to be invalid, the replica database can be rolled back to a point before the problematic update. Advantageously, the disclosed system can be used to implement a variety of data validations on top of a database replication process to protect the replica database from receiving undesired updates. |

Incrementally accumulating in-process performance data and hierarchical reporting thereof for a data stream in a secondary copy operation
Each data stream in a backup job is individually tracked by data agent(s) and media agent(s) in its path, generating performance data packets in-process and merging them into the processed data stream. The data stream thus incrementally accumulates performance data packets from any number of successive backup processes. The in-process tracking also captures hierarchical relationships among backup processes and in-process subtending tasks, so that the resulting performance report can depict parent and child operations. The hierarchical relationships are embedded into the performance data packets and may be analyzed by parsing the data stream. The media agent transfers the data packets belonging to the secondary copy to secondary storage. The media agent analyzes the performance data packets in the data stream and generates a performance report, which covers the data stream from source to destination, based on the accumulated information carried by the performance data packets. The media agent illustratively stores the performance report locally as a flat file. |

In a signal processing arrangement a first and a second input signal associated with the rotating object are received at signal inputs. Amplitude processing blocks are connected to the signal inputs and each have an adjustable gain. A trigonometric processing block has inputs coupled to outputs of the second amplitude processing blocks via respective signal paths. The trigonometric processing block is configured to determine a magnitude value and a phase value based on signals at its inputs. The signal processing arrangement further has compensation blocks configured to store values at the inputs of the trigonometric processing block as respective peak values, when the phase value assumes a respective phase value. A gain value is determined by applying a respective regulation function to respective amplitude errors being based on the peal values, and the gains of the amplitude processing blocks are adjusted based on the respective gain values. |

Encoder
An encoder includes a scale having a pattern to be detected, a detecting sensor outputting a signal corresponding to the pattern, a position calculator calculating a relative position between the scale and the detecting sensor based on the signal, a position data storage storing the calculated position data, and a position estimator estimating a relative position between the scale and the detecting sensor at a calculation-target time point based on the stored position data. The position estimator estimates the position at the calculation-target time point based on positions at first and second time points each preceding the calculation-target time point by a predetermined time. The position estimator processes position data in a first time width centered on the first time point and position data in a second time width centered on the second time point to calculate the positions at the first and second time points. |
