Abstract: A computer-implemented method, system and computer program product for accurately identifying an execution time of a performance test. Network latency data is grouped into clustered groups of network latency data. Furthermore, the performance test execution times for the same group of performance tests run in the local and remote cluster environments are obtained. The test execution times impacted by network latency (compensation times) are then determined based on such obtained performance test execution times in the local and remote cluster environments. Such compensation times are then grouped into clustered groups of compensation times. A regression model is built to predict a performance test execution time impacted by network latency (compensation time) using the clustered groups of network latency data and compensation times.

Abstract: A self-adaptive electric toothbrush includes a handle and a brush head. A vibrating motor is arranged in the handle. Bristles are arranged on the brush head. An output shaft of the vibrating motor extends out of the handle and is connected to the brush head through a delay structure. By the delay structure, the brush head remains stationary or the amplitude of the oscillation of the brush head is less than the amplitude of the oscillation of the output shaft after the vibrating motor is activated and before pressure is applied to the bristles. After pressure is applied to the bristles, the amplitude of the oscillation of the brush head is greater than the amplitude of the oscillation before pressure is applied. In the self-adaptive electric toothbrush, before the pressure is applied, the brush head is stationary or the amplitude of oscillation is small.
