Ultrasonic Detection Technology

Recently, filling mining is becoming more and more important in the mining industry and has been used widely. In order to better control the process of paste filling mining and acquire the accurate amount of filling material used, and to reduce the waste of paste filling material, we should detect in real time the paste flow in the pipe during the process of filling. This paper introduces in detail the basic principle of ultrasonic detection technology and the hardware composition and working principle of the on-line detection system. The author uses the theory of unascertained error analysis of detecting data and implements ultrasonic detection technology to realize on-line detection of paste filling pipe flow.

A new modeling technique called Dynamic Data System (DDS) is introduced for signature analysis. A one-horsepower electric motor experiment is used to demonstrate the methodology. The ‘normal’ operation is simulated by idling runs and eccentric loads representing the ‘defective’ operations. A DDS Monitoring Technique, by employing statistical quality control theory, is developed to monitor the operations of imposed electric motor defects. It takes thirteen seconds for data processing and calculation of a control variable value from an On-line programmed microprocessor to provide the control justification. The DDS Monitoring Technique proves to be effective and sensitive in identifying the operational status of a mechanical system.

We report the results from two experiments investigating proficient Japanese-speaking learners' processing of reflexive object pronouns in English as a second language (L2). Experiment 1 used a timed grammaticality judgement task to assess learners' sensitivity to binding Principle A under processing pressure, and Experiment 2 investigated the time-course of reflexive anaphor resolution during L2 reading using the eye-movement monitoring technique. Taken together, our results show that despite having demonstrated native-like knowledge of reflexive binding in corresponding untimed tasks, the learners processed English reflexives differently from native speakers in that they took into consideration a matching discourse-prominent but binding-theoretically inappropriate antecedent when first encountering a reflexive. This suggests that unlike what has been reported in corresponding monolingual processing research (Sturt, 2003), initial antecedent search in L2 English is not constrained by binding Principle A.
