Some embodiments provide application performance management tools with a service monitor that operates on a number of different mobile devices to track and monitor services that an application is using. In some embodiments, the service monitor stores a log relating to the use of the service each time the application uses the service. The application performance tool also includes an error monitor to detect an application error and report the application error to a performance monitoring server along with one or more logs relating to the use of the service when the error is detected. The performance monitoring server then provides an error report with the one or more logs to assist a developer in diagnosing the cause of the error with the application.

A method for application performance data collection includes steps or acts of: customizing a performance tool for collecting application performance data of an application; modifying the application by inserting the performance tool while the application does not need to be rebuilt from the source; executing the application; and collecting the application execution performance data such that only interesting data is collected. Customizing the performance tool proceeds by implementing at least one configurable tracing function that can be programmed by the user; compiling the function(s) into an object file; and inserting the object file into the performance tool using binary instrumentation.

The sleeve tool is high in tightening and loosening efficiency and use efficiency, wide in application range, high in performance and long in service life.

In an aspect, provided are methods, systems, and apparatuses comprising receiving a query specifying one or more materials of a floor / ceiling assembly and / or a classification or result, determining one or more media files responsive to the query, and providing the one or more media files for playback.

A sound deadening tool and a sound deadening musical performance tool according to embodiments of the invention have a high sound deadening effect on stringed instruments while various senses of discomfort during a musical performance, such as a musical pitch, expressive power, and a touch feeling are suppressed to a minimum level, and the sound deadening tool can easily and securely be used and attached. A vibration suppressor of the sound deadening tool includes a pair of metallic weights and that is fixed while side faces of a saddle are sandwiched therebetween, and the pair of metallic weights and have a substantially identical mass. The pair of metallic weights and is fixed by a pair of tightening screw, and the pair of metallic weights includes recesses that are not in contact with a string attached to the saddle. Plate-like antivibration members include sheet attaching recesses, suction sheets adhere to the sheet attaching recesses by double-sided adhesive tapes, and the plate-like antivibration members are detachably attached to the sound box by the suction sheets. The sound deadening musical performance tool includes an electronic module that is disposed at the back of a saddle of a stringed instrument including a sound box and at a position in an opposite direction to a neck. The electronic module enables a player to listen to sound-deadened musical performance with a usual sound volume through an earphone in an upper surface of the detachably-attached plate-like antivibration member.

The invention discloses a stage lifting method for lifting and lowering a performer and performing tools in a balanced mode. The method is characterized in that the performer and tools related to performance are placed on the upper end surface of an upper supporting base; an electromotor runs, power is transmitted to a threaded rod through a power transmission mechanism, and the threaded rod axially rotates around the own body under the effect of power provided by the electromotor; the threaded rod axially rotates around the own body and drives a driving block to axially make movements close to a fixed block along the threaded rod, therefore a lifting device is switched to a stretching state from a contraction state, and the performer is lifted to the highest point; after the lifting stageis used, the electromotor runs reversely and makes the threaded rod rotate reversely, therefore the lifting device is switched to the stretching state from the contraction state, the upper supportingbase can recover to the original state, and the lifting stage can recover to the original state.

The invention discloses an ultra-fine cemented carbide tool and a method for preparing a surface nano-composite film thereof, belonging to the field of metal material and machining technology. The invention is characterized by providing an ultra-fine cemented carbide tool surface-modified by the nano-composite film, wherein the film is a zirconium nitride nanocrystalline-doped diamond-like film prepared by using an arc iron plating method and forms a high-performance tool system with an ultra-fine grain WC-Co cemented carbide micro-drill with the WC grain of 0.1-0.3 microns, a printing needlehead, a milling cutter, a mould and other tool base materials. The method has the advantages of: causing the ultra-fine cemented carbide tool to have the surface hardness higher than 40GPa and the thermal stability higher than 500 DEG C, the frictional coefficient lower than 0.1 and being capable of remarkably enhancing the machining quality and the service life of the tool. The tool and the method are particularly suitable for the technical field of fine machining of machining.

The method comprises the steps that (1) a Task Monitoring Model (TMM) is established, wherein the TMM comprises (1-1) a running model for a task mode, (1-2) a task monitoring mechanism and (1-3) display of task running and association information in a relation description graph, so that automatic recognition is realized; and (2) the TMM is applied to a multi-core programming model to realize a monitoring and tracking method based on a package library technology, including analysis of a taskexecution mechanism of a library during GCC OpenMP running, an OpenMP task monitoring mechanism based on simulated scheduling and an OpenMP task monitoring mechanism based on additional information.Through the method, a performance tool can monitor newly added execution dimensions, namely tasks; and necessary performance information is provided for performance analysis staff to recognize programbehaviors and discover performance bottlenecks, therefore, programs are optimized, and running efficiency is improved.

A shaping tool includes a cooling system having one or more cooling passages configured for enhanced cooling. The cooling passages provide latent heat cooling of a heated material that is in contact with a shaping surface of the tool. Cooling fluid flows along the cooling passages in a two-phase flow regime in which a portion of the cooling fluid is liquid and a portion of the cooling fluid is vapor. A two-phase portion of the cooling passage can be shaped to follow a three-dimensional contour of the shaping surface. Opposing walls of the cooling passage can be provided by passage surfaces of separately formed pieces of the tool. The latent heat cooling provided by suitably configured cooling channels extracts more heat from the material being shaped in the tool than traditional cooling systems.
