基于多重分形谱的转子系统故障诊断与参数优选
Published 2013-01-01“…Because of the robustness of one dimensional time series reconstruction G-P algorithm to extract the fault omen is poor,especially influenced by a sensitive noise in the measured signal.A noise reduction method is proposed based on detrended fluctuat ion analysis(FDA) and kernel principal component analysis(KPCA),the eigenvalue extraction algorithm based on Mult ifractal spectrum is presented.Through pseudo-phase portrait to determine the weighting factor threshold,optimize and choose parameter and compare with the defects of single G<sub>P</sub> algorithm,and combine with the 3 kinds of rotor system common faults,the stability and accuracy of eigenvalue extraction of this method is analyzed,the results prove that,the diagnosis result is good.…”

A Qualitative Study of the Causes of Irreligiousness Boy Adolescents in Religious Families
Published 2024-12-01“…In order to collect data, a semi-structured focal type interview was used. The analysis of the contextual theory by the method of Charmaz (2014) revealed three components: a) The nature of atheism contained three core codes, which were: 1) the desire to make decisions based on individual diagnosis, 2) choosing religion as one from the types of life values, 3) acting based on individual diagnoses; b) the class of reasons for atheism with axial codes; 1) individual-oriented causes (with open codes of awakening instincts, curiosity and avoiding advice, inability to manage instincts) and 2) other-oriented causes (with open codes of friends and family, the role of society and the media, and social interactions) and c) the category of how to avoid religion With the main codes: 1) matching with the congregation (with open codes of matching with friend and matching with family), 2) finding contrary evidence for religiosity (inference in favor of atheism from social events, overgeneralization in favor of atheism) and 3) Finding supporting evidence for atheism (finding fault with religious people and positive perceptions of religion). …”

Dynamic Response of Rub Caused by a Shedding Annular Component Happening in a Steam Turbine
Published 2015-01-01“…The shafting abrasion defects shortened the service life and damaged the unit. To identify the fault in time, the dynamic response of rub caused by a shedding annular component was studied as follows: (I) a rotor-bearing model was established based on the structural features of certain steam turbines; node-to-node contact constraint and penalty method were utilized to analyze the impact and friction; (II) dynamic response of the rotor-bearing system and the shedding component was simulated with the development of rub after the component was dropping; (III) fault features were extracted from the vibration near the bearing position by time-domain and frequency-domain analysis. …”
