Abstract As a common soil type, saline alkali land is widely distributed in China. The properties of are relatively special, and the utilization rate low. In current situation scarce resources, improvement has attracted much attention, it particularly urgent to speed up land. methods different. This paper analyzes causes formation land, discusses harm comprehensively expounds physical methods, chemical biological combination treatment, further puts forward development trend treatment technology
A prime-target interference task was used to investigate the effects of cognitive aging on reactive and proactive control in which frequency confounds feature repetitions were eliminated from measures. We distributional analyses explore dynamics two functions by distinguishing strength incorrect response capture efficiency suppression control. For control, within-trial conflict between-trial adaption analyzed. The statistical analysis showed that there no reliable for both young older...
Abstract The main bearing supports the rotation of shaft a wind turbine. It bears heavy dead weights as well variable speed dynamic loading during operations; thus, it is vulnerable part in turbine drive train. Because low and time‐varying operations bearing, vibrations generated by faults are often weak response amplitudes, frequency range, smeared damage feature energy. As result, applicability conventional acceleration envelope analysis (AEA) technique, traditionally effective technology...
An improved method using kernel density estimation (KDE) and confidence level is presented for model validation with small samples. Decision making a challenging problem because of input uncertainty only samples can be used due to the high costs experimental measurements. However, provides more decision makers when improving prediction accuracy at same time. The introduced optimum sample variance determined new in increase credibility validation. As numerical example, static frame challenge...
Bolt‐jointed structure is widely used in engineering fields. The dynamic characteristics of bolt‐jointed are complex, and there a variety uncertainties the jointed structure. In this study, modeling updating typical investigated. terms, three‐dimensional brick elements to represent substructures, thin‐layer with virtual material properties employed joint interface. Modal tests experimental modal analysis substructures built‐up performed. A hierarchical model strategy based on Bayesian...
To establish a high-fidelity model of engineering structures, this paper introduces an improved Bayesian updating method for stochastic dynamic models based on frequency response functions (FRFs). A novel validation metric is proposed first within the theory by using normalized half-power bandwidth transformation (NHBFT) and principal component analysis (PCA) to process analytical experimental functions. Subsequently, traditional approximate computation (ABC) are integrating NHBFT-PCA...
Accurate shaft speed extraction is crucial for synchronous sampling in the fault diagnosis of wind turbines. However, traditional narrow-bandpass filtering techniques face limitations when dealing with large fluctuations rotational speed, hindering accurate construction an instantaneous phase resampling a shaft. To overcome this, we propose tachometer-less based on Scaling-Basis Chirplet Transform, tailored to turbine’s structure and operating conditions. The algorithm generates...
Dynamically evaluating the outcomes of our actions and thoughts is a fundamental cognitive ability. Given its excellent temporal resolution, event-related potential (ERP) technology has been used to address this issue. The feedback-related negativity (FRN) component ERPs studied intensively with averaged linked mastoid reference method (LM). However, it unknown whether FRN can be induced by an expectancy violation in antonym relations context LM most suitable approach. To these issues,...
Abstract A novel method for bearing damage detection is introduced in this paper. In conventionally operated bearings, when a component damaged, precise frequency response features are available associating with the damaged components. some applications such as wind turbines, speed of shaft very low, and contents damage‐induced impulsive low well. Therefore, those vibration responses mixed up gearbox operational hence unable to be separated simple band‐pass or high‐pass filters. Hence, it...
