A method may include receiving a continuous query identified by an archived relation associated with an application. The method may also include generating a physical query plan. Additionally, the method may include constructing a structured query language (SQL) equivalent expression corresponding to an attribute utilized by the operator and/or constructing an output SQL expression for the identified operator based at least in part on the SQL equivalent expression. Additionally, the method may include constructing the archiver query for the identified operator based at least in part on the output SQL expression. Further, the method may include executing the archiver query to obtain a result set of data records related to the application and/or generating a snapshot output of one or more data values related to the application based at least in part on the result set of data records.

Generation of archiver queries for continuous queries over archived relations

This disclosure is directed to seal assemblies for a turbomachine. The seal assemblies include stationary and rotating components and at least one interface between the stationary and rotating components. The seal assembly further includes a self-lubricating lattice element made of carbon or a carbon-based material. The self-lubricating lattice element may have a porous and compressible microstructure capable of retaining a liquid substance. During engine operation, the self-lubricating lattice element can compress and expel some portion of the liquid substance to form a liquid-containing layer between the rotating and stationary components of the seal assembly. Also described herein are self-lubricating wear sleeves for use in other portions of the turbomachine.

Example bearing lubrication system and methods of operating the same are disclosed herein. An example closed loop system to provide a lubricant to a fluid pump includes a lubrication flow network disposed within the fluid pump; a sensor fluidly coupled to the fluid pump to measure a condition of a fluid that is to enter the lubrication flow network; a first transport bus fluidly coupled to the lubrication flow network, the first transport bus to transport an inert gas; a controller to actuate a valve fluidly coupled to the first transport bus, the controller to transmit signals to the valve based on the condition of the fluid to cause the valve to open or close; and a separator fluidly coupled between an outlet of the fluid pump and the first transport bus, the separator to separate the fluid and the inert gas.

Bearing lubrication systems and methods for operating the same

This disclosure is directed to seal assemblies for a turbomachine. The seal assemblies include stationary and rotating components and at least one interface between the stationary and rotating components. In some examples, seal assembly includes an oleophilic coating disposed between the stationary and rotating components. The seal assembly may include a surface texture to enhance the oleophilicity of the surface coating disposed between the stationary and rotating components. In other examples, the seal assembly includes an oleophobic coating disposed between the stationary and rotating components. The seal assembly may include a surface texture to enhance the oleophobicity of the surface coating. During operation, the oleophilic seal assembly features retain lubricant between the stationary and rotating components and the oleophobic seal assembly features inhibit the escape of lubricant from the contact regions between the stationary and rotating components.

Surface treatment for seal assemblies

A continuous query identified by an archived relation of an application may be received. A physical query plan may be generated for the continuous query and/or a child operator plan may be identified. A buffer operator may be inserted between the child operator and its parent operator and/or the event information from the child operator may be stored in the buffer operator. A query operator may be identified in the physical query plan. It may be determined that the query operator identified in the physical query plan is a same type as a second query operator in a second continuous query concurrently executing. Further, a combined query plan may be generated based at least in part on the query operator identified in the physical query plan being the same type as the second query operator in the second continuous query.

Operator sharing for continuous queries over archived relations

Techniques for managing real-time business event analysis and monitoring are provided. In some examples, a logical request may be received at a business intelligence server configured with a continuous query service. Additionally, the continuous query service may be configured to translate the logical request into a physical request. Further, business intelligence information may be provided based at least in part on querying against an event data stream with a continuous query configured based at least in part on the physical request translated by the continuous query service.

Real-time business event analysis and monitoring

Provided are methods, systems, and computer-program products for responding to a natural language communication, sending a response to request additional information from a user, and exposing an invocable method for accessing a virtual database. Some examples relate to a bot server that can respond to natural-language messages (e.g., questions or comments) through a messaging application using natural-language messages. Other examples relate to storage of event data associated with a web page or a mobile application. Event data can describe one or more actions performed in relation to the web page and/or the mobile application. Other examples relate to behavioral analytics of the event data.

Techniques for implementing mechanisms for chaining continuous queries are provided. In some examples, results of a first continuous query may be stored in a data object. For example, the first continuous query may be configured to process business event data and store the results in the data object. Additionally, a second continuous query may then be processed based at least in part on the results stored in the data object.

Mechanism to chain continuous queries

An apparatus and method for determining lubrication contamination or deterioration in an engine or a lubricant system of an engine can include at least one sensor provided in the lubricant system. The sensor can sense an aroma of a lubricant or the air around the lubricant to measure a chemical composition or an aromatic. The sensed chemical composition or aromatic can be compared to a baseline or threshold to determine a particular contamination type or deterioration level of the lubricant.

Techniques for managing continuous queries that include subqueries are provided. In some examples, a continuous query that includes at least a subquery may be identified. Additionally, the subquery may be processed to obtain a first result or generate a logical subquery plan. Further, in some instances, the continuous query may then be processed based at least in part on the first result from the subquery or by merging a logical continuous query plan with the logical subquery plan. This may result in obtaining a second result via querying a data source with the continuous query that is based at least in part on the first result from the subquery and/or the merged plans.

Managing continuous queries in the presence of subqueries

Improved techniques are provided for processing streams of data. The duration of the time that an event is eligible for remaining in a time-based window can be variable for different events received via the same event stream. In certain embodiments, the duration of time that an input event spends in a time-based window is a function of one or more values of one or more attributes of the event. Since different events can have different one or more attribute values, the different events can spend different amounts of time in the time-based window for that event stream. The amount of time that an event spends in a time-based window can be controlled via the one or more attributes of the event.
