The device uses two piezoelectric ceramics as the core of the sensor, one as the active chip to generate ultrasonic wave, and the other as the receiving chip to receive the ultrasonic output electrical signal. The device analyzes the electrical signal related to the connection state output from the receiving chip on the built-in circuit board, and then sends the data which can represent the bolt connection state after analysis to the remote receiver in a wireless way, and gives an alarm at the receiving end for the data exceeding the threshold value. In addition, the device can automatically switch between working mode and sleep mode, greatly reducing power consumption, and can work for a long time with solar power supply system, without frequent battery replacement. The experimental results show that the device can evaluate the current connection state of bolts and work stably for a long time. It has a good prospect in the field of bolt connection condition monitoring.","PeriodicalId":285980,"journal":{"name":"2020 7th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128647178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main challenge is the uncertainty of wind power generation (WPG). Based on WPG forecasting, the reinforcement learning (RL) method is used to overcome the impact of WPG uncertainty. The (RL) method used is classic Q-learning. Compared with other (RL) methods, Q-learning is widely applied and easy to converge. Especially, (RL) methods can realize online decision-making, and the decision-making will tend to be optimal. The simulation results show that the method in this paper can effectively reduce the uncertainty of WPG and increase the revenue of wind farms.","PeriodicalId":285980,"journal":{"name":"2020 7th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129079671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work focuses on the mechanism of the wetting transition. It analyses the stress condition of the gas-liquid interface, providing a theoretical result of the wetting transition. The results show that there are four forces acting on the interface during the wetting transition and in the depinning process only one of which changes with time and the other remains unchanged. Moreover, this work provides the speculation of the possible cause of meniscus collapse (touch-down) with an asymmetric configuration. Since wetting transition occurs at the nanoscale, it might be influenced by the potential field, resulting in symmetry breaking which leads to asymmetric representation. Although this work is just a theoretical analysis, it provides a different perspective to the study of wetting transition and we anticipate this assay could offer reference to the research in the superhydrophobic field.","PeriodicalId":285980,"journal":{"name":"2020 7th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129693787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field of condensed matter physics, it is clear that there are certain kinds of quasiparticles which have similar behaviors to Majorana fermions in the searches of topological superconductors and fractional quantum Hall effects. Especially, zero-energy Majorana fermion modes in two-dimensional topological superconductors show non-abelian anyonic statistical properties under exchange operations, which can realize the so-called topological quantum computation that is fault-tolerant on the hardware level. In this article the history and then introduce latest progress of Majorana fermions will be reviewed.

The longitudinal difference principle is used to locate the fault in the fault area.
