Abstract: Current physical resources utilization of a computing system as a whole is monitored. The number of queries concurrently being executed against a database by a database management system (DBMS) running on a computing system is monitored. A query plan for a received query to be executed against the database is generated. The query plan includes operators; the generation of the query plan includes generation of query-based statistics for the received query on a per-operator basis without consideration of the queries concurrently being executed. An estimated execution time of the received query is dynamically predicted using a machine-learning model based on the query-based statistics generated for the received query on the per-operator basis, the current physical resources utilization of the computing system, and the number of queries concurrently being executed. The received query is executed against the database based on the dynamically predicted estimated execution time for the received query.

The shield tunnel segment structure includes segment blocks sequentially spliced in a circumferential direction. Each segment block forms a closed annular segment structure, and outer diameters of adjacent annular segment structures gradually increase in an axial direction. At least two adjacent segment blocks of the same annular segment structure form an annular inner groove, and at least one segment block of the adjacent annular segment structures is provided with an inner bump which matches the annular inner groove. At least two adjacent segment blocks of the same annular segment structure form an annular outer groove, and at least one segment block of the adjacent annular segment structures is provided with an outer bump which matches the annular outer groove. The annular outer grooves and the annular inner grooves are staggered in the circumferential direction.

Abstract: A method and terminal for reducing coupling sensitivity deviations, and an apparatus having a storage function are provided. Sensitivities of different channels are collected to obtain sensitivity deviations between adjacent channels when a sample smart terminal is at a first predetermined position. It is determined whether one of the sensitivity deviations is greater than a predetermined deviation threshold. If one of the sensitivity deviations is greater than the predetermined deviation threshold, it is determined whether a cause of the sensitivity deviation comprises a signal scattering effect and/or a signal radiation effect. A smart terminal is then produced according to determination of the cause.

Abstract: Disclosed in the present application are a method for reducing SGLTE coupling de-sense and a mobile terminal, the method including: filtering out an LTE network frequency band in a signal transmitted by a signal transmission end of a GSM; and filtering out a network frequency band in a signal of a signal reception end accessing the GSM other than a GSM network frequency band. Employing the present application may eliminate mutual interference between a GSM signal and an LTE signal due to the GSM network frequency band and the LTE network frequency band getting too close to each other, which greatly alleviates SGLTE mobile terminal coupling de-sense situation.
