Model-based semantic text searching
Techniques and systems are described for performing semantic text searches. A semantic text-searching solution uses a machine learning system (such as a deep learning system) to determine associations between the semantic meanings of words. These associations are not limited by the spelling, syntax, grammar, or even definition of words. Instead, the associations can be based on the context in which characters, words, and/or phrases are used in relation to one another. In response to detecting a request to locate text within an electronic document associated with a keyword, the semantic text-searching solution can return strings within the document that have matching and/or related semantic meanings or contexts, in addition to exact matches (e.g., string matches) within the document. The semantic text-searching solution can then output an indication of the matching strings. |

The system also terminates the receiving where the counter value is above the saturation threshold. |

Automated configuration parameter tuning for database performance
Embodiments implement a prediction-driven, rather than a trial-driven, approach to automate database configuration parameter tuning for a database workload. This approach uses machine learning (ML) models to test performance metrics resulting from application of particular database parameters to a database workload, and does not require live trials on the DBMS managing the workload. Specifically, automatic configuration (AC) ML models are trained, using a training corpus that includes information from workloads being run by DBMSs, to predict performance metrics based on workload features and configuration parameter values. The trained AC-ML models predict performance metrics resulting from applying particular configuration parameter values to a given database workload being automatically tuned. Based on correlating changes to configuration parameter values with changes in predicted performance metrics, an optimization algorithm is used to converge to an optimal set of configuration parameters. The optimal set of configuration parameter values is automatically applied for the given workload. |

Conditional response fulfillment cache for locally responding to automated assistant inputs
Implementations set forth herein relate to conditionally caching responses to automated assistant queries according to certain contextual data that may be associated with each automated assistant query.

For example, a query that users commonly ask prior to leaving for work can have a corresponding assistant response that depends on features of an environment of the users. This unique assistant response can be cached, before the users provide the query, to minimize latency that can occur when network or processing bandwidth is unpredictable. |

Automated fault injection testing
An automated fault injection testing and analysis approach drives fault injection into a processor driven instruction sequence to quantify and define susceptibility to external fault injections for manipulating instruction execution and control flow of a set of computer instructions.

Based on accumulation of fault injections and results, a repeatable injection chain and probability identifies an external action taken on a processing device to cause unexpected results that differ from an expected execution of a program or set of computer instructions. |

Some micro object stores (MOSs) are moved to the new physical server(s) through a meiosis process. The storage devices associated with the moved MOSs are unmounted from the original servers and mounted to the new server(s). The meiosis continues until the cluster grows to full capacity. The scaling is dynamic and efficient since no data copy is involved in the meiosis and the initial resource cost is optimized. |

A type of the new feature can be classified in accordance with an analysis of a structure of the current data that has been clustered together based on a threshold spatial closeness, and semantic labels of the pre-mapped data from the high-resolution sensor system can be updated based on the new feature described by the clustered current data. |

Visualization of high definition map data
The autonomous vehicle generates an overlapped image by overlaying HD map data over sensor data and rendering the overlaid images. The visualization process is repeated as the vehicle drives along the route. The visualization may be displayed on a screen within the vehicle or at a remote device. The system performs reverse rendering of a scene based on map data from a selected point. For each line of sight originating at the selected point, the system identifies the farthest object in the map data. Accordingly, the system eliminates objects obstructing the view of the farthest objects in the HD map as viewed from the selected point. The system further allows filtering of objects using filtering criteria based on semantic labels. The system generates a view from the selected point such that 3D objects matching the filtering criteria are eliminated from the view. |

Startup method of francis turbine and francis turbine
A startup method of a Francis turbine according to an embodiment includes: a first rotation-speed increasing step in which a rotation speed of the runner is increased by opening the guide vane at a first opening; a second rotation-speed increasing step in which the increase in the rotation speed of the runner is accelerated by opening the guide vane at a second opening that is larger than the first opening after the first rotation-speed increasing step; and a rotation-speed regulating step in which the rotation speed of the runner is regulated to a rated rotation speed by opening the guide vane at a no-load opening after the second rotation-speed increasing step. The first opening is an opening that is half or less than the no-load opening. |

Inertial pneumatic wave energy device
A buoyant wave energy device is disclosed that incorporates an open-bottomed tube of substantial length in which is partially enclosed a first body of water that oscillates in response to wave action. The device incorporates a buoy to which an upper end of the tube is connected and inside of which is trapped a second body of water of substantial mass. A differential phase in the oscillations of the water trapped in the tube, and the oscillations of the buoy of augmented mass, result in the periodic compression of a pocket of air trapped at the top of the tube, and in the subsequent expulsion of pressurized air through a turbine, thereby generating electrical power. |

Internal combustion engine/generator with pressure boost
This invention relates to improvements in internal combustion engines. More particularly it relates to increased levels of usable electrical energy production and fuel efficiency within a relatively fixed speed, cam-track style Engine/Generator when combined with the secondary injection or injections of a rapidly expanding medium (usually water) into the engines combustion chambers during and after the combustion process has been initiated. The injection of said medium causing reduced fuel consumption, increased cylinder pressure, an extended usable piston stroke length, and increased usable energy production, while reducing the temperature of the combustion gases in order to control or eliminate the production of the pollutant, NOx and to further reduce thermal pollution exhausted into the atmosphere. |
