2008 1471 Astrophysics - High Energy Astrophysical Phenomena Abstract: We performed a systematic search for X-ray bursts of the SGR J1935+2154 using the Fermi Gamma-ray Burst Monitor continuous data dated from 2013 January to 2021 October. Eight bursting phases, which consist of a total of 353 individual bursts, are identified. We further analyze the periodic properties of our sample using the Lomb-Scargle periodogram. The result suggests that those bursts exhibit a period of ~238 days with a ~63.2% duty cycle. Based on our analysis, we further predict two upcoming active windows of the X-ray bursts. Since 2021 July, the beginning date of our first prediction has been confirmed by the ongoing X-ray activities of the SGR J1935+2154.

The system is developed for the real-time data processing. The data include the sensor data from TS02 total station and the data from the CCD processing system. It was introduced that the TS02 total station which produced by the Leica company. The GeoCOM application interface which provided by Leica company for the client to exploit it was introduced. The main controller of the system is C8051F021. The protocol of I2C bus is simulated by software. System works in the timing interrupt way. The angle error is calculated and transferred to remote receive device. All data is displayed on LCD. The hardware and software design method is present. The system has been applied to the angle monitor equipment. The system is stable and reliable in practical application. 2012 IEEE.

The solar irradiance monitor (SIM) with the design accuracy of 5 used to monitor the secular changes of the total solar irradiance on FY-3 satellite takes the sun-scanning measurement method on-orbit. Compared to the sun-tracking measurement method this method simplifies the structure and cuts the cost but the measuring accuracy is affected by the sun-synchronous orbit sunlight incidence angle and the installing angle of the SIM in the satellite. Through the ground calibration experiment studies on the affection of different sunlight incidence angles to the measurement accuracy. First by the satellite tool kit (STK) simulation software simulates the orbital parameters of the sun-synchronous satellite and calculates the Sun ascension and declination at any time. By the orbit coordinate transformation matrix gets the components of the Sun vectors to the axes of the satellite and base on the components designs the field of view and the installing angles of the SIM. Then designs and completes the calibration experiment to calibrate the affection of the incidence angles. Selecting 11 different angles between the sunlight and the satellite X-axis measures the total solar irradiance by the SIM at each angle and compares to the irradiances of the SIAR reference radiometers and gets the coefficient curves of the three channels of the SIM. Finally by the quadratic fitting gets the correction equations on the incidence angles: R 1=5.7110-52 -2.45310 -3+1.0302 R2=2.8410-5-1. 96510-3+1.0314 and R3 =1.7210 -52-4.18410-4+0.9946. The equations will aimprove the on-orbit measurement accuracy of the solar irradiance and are very important to the on-orbit data processing after the satellite launched. 2011 SPIE.

In order to realize the real-time state data monitor of the electromechanical actuator(EMA) the EMA and other subsystem establish a ground half physical experiment simulation platform based on the CAN bus. The CANoe software decodes the received EMA CAN data and showes the result in the image window. The decoding data contains the EMA current motor operation state EMA angle and etc. Through these real-time display data the EMA operation state could be monitored and the EMA failure could be located fastly. 2011 IEEE.

The main constrained problem of the video monitoring and storage system is the contradiction between large field of view and storage space limitations. Not all of the video information introduced by the image sensors need to be recorded especially for some tracking system which has appointed functions to track specifically kinds of targets. For instance the system not only works for single target if the monitor is appointed for human face tracking but also can work for multi-targets. High reconstruction resolution in the fovea region enables the successive application of recognition modules without sacrificing their performance the best system appears to be concentrating on human face only and all the others considered being background the low reconstruction resolution in the periphery helps to reduce the video data. 2010 IEEE. the background regions needn't to be recorded in detail. For this purpose this letter presents a real-time foveate storage system which efficiently represents the video image in log-polar coordinates with the foveate point centered on the target
