摘要:
Methods, systems, and devices are described that enable the parsing and interpretation of common types of math problems in multiple choice format that are found in math textbooks and standardized tests.
摘要:
A strain and crack sensor senses an amount of strain induced in an object. A receiving planar antenna has a first resonant frequency and is configured to receive a querying signal at the first resonant frequency. A transmitting planar antenna has a second resonant frequency that is twice the first resonant frequency. At least one of the receiving planar antenna and the transmitting planar antenna is bonded to the object so that at least one of strain induced in the object or a crack formed in the object causes a shift in at least one of the first resonant frequency or the second resonant frequency. A matching element is in electrical communication with the first planar antenna and the second planar antenna. The matching element is configured to cause the transmitting planar antenna to radiate a response signal in response to the querying signal.

摘要:
A method and system are described for communicating within a system, which may be along tubular members and used during gravel pack operations. The method includes constructing a communication network and installing the communication nodes along the gravel pack system. The communication nodes are used to monitor the formation of the gravel pack for voids or gaps during the gravel pack operations. Once the gravel pack is installed, the gravel pack operations may be used for hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development, and/or hydrocarbon production.

A method and system are described for communicating within a system, which may be along tubular members and used during cementing installation operations. The method includes constructing a communication network and installing the communication nodes along a wellbore. The communication nodes are used to monitor the fluids adjacent to the communication nodes during the cementing installation operations. Once the cement is installed, the cementing installation operations may be used for hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development, and/or hydrocarbon production.
摘要:
A method and system are described for using different types of communication networks along one or more tubular members. The method includes constructing a communication network along one or more tubular members, which may access a subsurface region and using the communication network in hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development, and/or hydrocarbon production.
摘要:
Methods, systems, and devices are described that enable parsing and interpretation of logical statements in “native style” with syntax that is very similar to that of first-order-logic (FOL) and “prose style” with which logical statements are expressed in English prose, or a mixture of both English prose and FOL.
摘要:
Methods, systems, and devices are described that provide for entry of hybrid mathematical and natural language statements in a mathematical notation friendly language and system for a rigorous yet practically tractable formal grammar to distill the essence of natural math notation. Hybrid statements mixing natural language and symbolic expressions including assertions, commands, queries, and/or deductions may be entered that are processed according to natural language processing. The statements, along with the math objects are evaluated, and one or more results output. Furthermore, systems may provide automatic construction of one or more solution narratives that can be beneficial to student users pedagogically.
