The impact of insecure attachment on hoarding behavior (HB) has been supported by empirical evidence. However, scant literature has focused on how anthropomorphism (attributing human-like traits, characteristics, or emotions to nonhuman objects) and hoarding beliefs (motivations for ownership) affect the relationship between insecure attachment and HB, especially among Chinese adolescents. Using a cross-sectional study, we reserved 903 participants (561 males, 342 females, M = 20.20, SD = 1.85, age range = 18-24 years) to complete self-report questionnaires about close relationships, anthropomorphism, saving beliefs, and saving inventory to investigate the mediating role of anthropomorphism and the moderating role of hoarding beliefs in the relationship between insecure attachment and HB. Attachment anxiety and avoidance had a positive relationship with HB, and anthropomorphism is a mediating factor in the association between attachment anxiety and HB. In addition, hoarding beliefs moderated the relationship between attachment anxiety and HB. This study further elaborated on the relationships between insecure attachment, anthropomorphism, hoarding beliefs, and HB, which might shed some light on adolescent clinical interventions. K E Y W O R D S anthropomorphism, attachment anxiety, attachment avoidance, hoarding behavior, hoarding beliefs Xueting Liu and Ying Cai contributed equally.
A highly robust active disturbance rejection controller (ADRC) is developed in this paper. The proposed ADRC consists of a tracking differentiator (TD) in the feed forward path, an extended state observer (ESO), and a nonlinear state error feedback control law (NLSEF) in the feedback path. The control theory, the structure of ADRC and the controller design are presented. LabVIEW is used for modeling, simulation and analysis of the dynamic system. Simulation results show that the proposed ADRC has excellent control performance, especially outstanding adaptability and robustness external disturbances and model uncertainties.
Demand for high-speed fiber optic gyroscope data acquisition and real-time record, the design of the SD Card as storage medium to large capacity fiber optic gyro high - speed real - time acquisition and bulk storage systems, The system by applying the sd2.0 protocol and fat32 file systems in the system, enable real - time Data Acquisition of fiber optic gyro and large capacity storage. Experiments have shown that the system properly designed, easy to use, high reliability to meet the actual demand, is of important practical significance.
Weak fault signal not only refers to the signal with very small amplitude, but also refers to the signal existing in the background of strong noise. Weak signal detection technology is widely used in communication, radar, magnetism, vibration measurement, medicine and other research fields. Based on the essence of chaos, this paper summarizes the research status of chaos at home and abroad, including the basic characteristics of chaos system, the basic characteristics of chaos, the chaotic dynamics model and the discriminant method of chaos. The different methods of chaotic weak fault feature extraction are analyzed, their advantages and disadvantages are pointed out, and the research trend is forecasted
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
