Abstract

Objective To study the impact of the home literacy environment on children's emotional regulation skills and the mediating role of the parent-child relationship between them. Methods A stratified cluster sampling approach was employed to select 1 626 preschool children from five kindergartens in Nanjing. Questionnaires were used to collect detailed information on the home literacy environment, children's emotional regulation skills, and the parent- child relationship. A mediation model was established using the Process program in SPSS macro, and the significance of the mediation effect was tested using the Bootstrap method. Results The findings revealed a positive correlation between the home literacy environment and children's emotional regulation skills (r=0.217, P<0.001), as well as parent- child intimacy (r=0.065, P<0.01). Conversely, a negative correlation was found between the home literacy environment and parent-child conflict (r=-0.129, P<0.001). Additionally, parent-child conflict demonstrated a negative correlation with children's emotional regulation skills (r=-0.443, P<0.001), while parent-child intimacy exhibited a positive correlation (r=0.247, P<0.001). The home literacy environment exerted a significant direct effect on children's emotional regulation skills (β =0.162, P<0.001), and the mediating effect of the parent-child relationship accounted for 25.54% of the total effect. Conclusions The home literacy environment significantly influences children's emotional regulation skills, with the parent-child relationship partially mediating this relationship.

Abstract

In order to prevent trip and damage of 110 kV power supply line caused by thunder and meanwhile satisfy demand of production increase, reform and extension design of ring network of 110 kV substation of Liuzhuang Coal Mine was done, lightning protection measures of overhead distribution lines including overhead ground wire and zinc oxide arrester were adopted according to its actual situation. The reform and extension design of ring network make whole power lines form a ring network of power supply, namely, the ring network can ensure to supply any load by power supply loop when a power line happens trip or damage caused by thunder, so as to solve reliability problem of power supply lines.

Abstract

To enhance the performance of result merging for distributed information retrieval（DIR）,a novel merging method was put forward,which was based on relevance between retrieved results and query.Improved latent semantic kernel（LSK） was combined with analysis of variance（ANOVA） kernel to calculate the relevance.Experimental results showed that the result merging precision of the combination of LSK and ANOVA kernel（CLA） is 16.79%,30.73%,20.37%,24.17%,14.25%,13.50% and 7.53% higher than that of Round-robin,ComMNZ,Bayesian,Borda,SDM,MEM and regression SVM respectively.CLA kernel method has better performance for result merging and is a practical method for result merging in DIR.

Abstract

As space-based cameras have advantages of lower energy consumption,higher accuracy,and easy to be miniaturized when they are used to observe space objects with middle or smaller sizes,this paper explores the orbit determination method and observability calculation method of space objects by space-based cameras.The advantages that the sun synchronous orbit is set as a space-based satellite orbit are analyzed and a space-based satellite orbit is designed by referencing several foreign space-based satellite orbits.Then the visible arc sections of space objects for different orbit types are simulated based on the space-based satellite orbit.According to the orbit measurement accuracy of existing space based optical observation equipment and errors of orbit dynamic model,the different system errors,random errors and dynamic model errors for the orbit measurements are added.Finally,the orbit determination precisions for space objects in different orbital altitudes are analyzed.Analysis results show that,for determining space target in low earth orbit with 6 of 7 minutes a day / two days of space-based optical measurement orbit data,the orbit determination precision is coincident with that of the United States of America cataloging(Two-line Elements,TLE) when the orbit measurement accuracy is better than 30″ and the dynamic model error is less than 50%.Moreover,for determining space target in earth synchronous orbit with 10 min / day of space-based optical measurement orbit data,the orbit determination precision is in the orbit accuracy range of the United States of America cataloging when the orbit measurement accuracy is better than 10 " and the dynamic model error is less than 50%.

Abstract

Direction of arrival (DOA) is an important parameter to be measured in pulse compression radar (PCR) systems. It is more favorable for DOA estimation to be done after pulse compression, because the targets have been separated in range domain and usually have higher SNR. But after pulse compression, only a single snapshot is available in each range cell. As a result, conventional DOA estimation methods can't be done frequently since they need many snapshots to work. To solve this problem, a single-snapshot DOA (SSDOA) estimation method based on compressed sensing is proposed in this paper. In spite of single-snapshot estimation, the proposed method provides higher estimation accuracy and target resolution without knowing the number of targets, especially in the case of multiple targets in the same range cell.

Abstract

A fast DOA estimation algorithm developed from MUSIC, which also benefits from the processing of the signals' polarization information, is presented. Besides performance enhancement in precision and resolution, the proposed algorithm can be exerted on various forms of polarization sensitive arrays, without specific requirement on the array's pattern. Depending on the continuity property of the space spectrum, a huge amount of computation incurred in the calculation of 4-D space spectrum is averted. Performance and computation complexity analysis of the proposed algorithm is discussed and the simulation results are presented. Compared with conventional MUSIC, it is indicated that the proposed algorithm has considerable advantage in aspects of precision and resolution, with a low computation complexity proportional to a conventional 2-D MUSIC.

Abstract

Efficient timing synchronization in an IDMA system must be obtained before signal detection and decoding. However, the research on timing synchronization in IDMA system has not been studied widely. In this paper a new timing acquisition scheme for asynchronous IDMA uplink based on sliding correlation is proposed and its performance in terms of the probability density function is developed. The simulation results show that the proposed scheme is effective even under high MAI conditions.
