Summary: This paper introduces an automated glitch detection pipeline for real-time detection of rotational glitches in pulsars, utilizing two algorithms of median absolute deviation and polynomial regression. The polynomial regression algorithm has been found to be significantly more effective based on simulations. The pipeline is currently implemented at the Ooty Radio Telescope and will be important for observing hundreds of pulsars in the upcoming era of large telescopes.

Summary: A microphone array is utilized to enhance the target signal and suppress non-target interference when measuring the SPL of a target noise source in an outdoor environment. A real-time calibration method is introduced to compensate for the SPL difference caused by the mismatch in a MEMS microphone array. The method has been experimentally verified and shown to provide accurate and robust SPL calibration.

Summary: In this study, a ultra-high-speed hybrid ceramic rolling element triboelectric bearing (US-HCTEB) was developed to monitor the real-time dynamic behavior and stability of bearing operation. The US-HCTEB showed superiority and reliability in durability tests and ultra-high rotating speed tests. The output performance of the US-HCTEB was evaluated under variable working conditions and structural optimization, with dry contact lubrication and low humidity found to be beneficial. An extremely fast acceleration and deceleration test program was conducted to evaluate the performance of the US-HCTEB under complex nonstationary conditions. The results demonstrated that the proposed US-HCTEB achieved high-resolution dynamic behavior identification and exhibited high reliability until bearing failure.
