The gap between the wealthy and the poor in Hong Kong continues to be large, leading to much of people having to look for bargains daily. While one may be able to search the web for the lowest price, the information on the web is scattered, and it is necessary to compare product names word-for-word. This process is exceptionally inconvenient for some older adults and people with disabilities. The Hong Kong society is pressing for an application that can tackle this problem. In this paper, we propose a framework to recommend the optimal price of the product in the Hong Kong market. The framework aims to speed up the price search with high accuracy. The problem is decomposed into name recognition and database query. The former is accomplished by utilizing the VGG-16 Convolutional Neural Network model pre-trained on the ImageNet dataset via transfer learning and feature matching with Scale-Invariant Features Transform (SIFT) and the colour histogram. The latter is performed on a daily updated MySQL database. The results of the recommendations were satisfactory in the experiments, with the accuracy of validating the CNN model reaching 90.614%.","PeriodicalId":166358,"journal":{"name":"2022 IEEE 5th International Conference on Electronics Technology (ICET)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115143628","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 intensity of electromagnetic pulse produced by laser is closely related to the output energy of laser. Through the simplified monopole emission model, this paper evaluates the relationship between electromagnetic pulse intensity and laser energy and power, obtains the linear relationship curve of electromagnetic pulse intensity with laser power, and predicts the electromagnetic pulse radiation environment of high-power laser device under the condition of laser output energy above 2MJ. Combined with the cavity structure of the laser device, the calculation method of electromagnetic pulse propagation and distribution is demonstrated.

Compared with traditional transformers, OVT has the advantages of optoelectronic isolation, wide frequency band, high accuracy and wide dynamic range, so OVT was highly expected when it appeared. However, at the early stage of OVT’s promotion, OVT was mainly used to measure power frequency voltage. Moreover, although the capacitive voltage transformer had many shortcomings compared with OVT, it could still well meet the needs of voltage measurement of the current operating equipment and CVT productions are more mature, so the further development of OVT was hindered. The development of traveling wave protection which requires the use of wide frequency band voltages that couldn’t be provided by CVT puts forward new application scenarios for OVT. This paper presents a practical scheme of passive optical voltage transformer in high voltage substations, which could contribute to the further popularization of OVT in substations.","PeriodicalId":166358,"journal":{"name":"2022 IEEE 5th International Conference on Electronics Technology (ICET)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127939726","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}

Blind interference suppression technology represented by power inversion (PI) algorithm is studied and can effectively suppress the interference under the condition of unknown interference direction by optimizing the beamforming weights to improve the signal to interference plus noise ratio (SINR). Taking anti-interference performance and implementation complexity as indicators, a PI algorithm implementation structure based on field programmable gate array (FPGA) is proposed to develop digital systems and build an anti-interference algorithm implementation system efficiently. Simulation results of sample matrix inversion (SMI), least mean square error (LMS) and recursive least square (RLS) algorithm, in four-element linear array with half-wavelength array spacing, are given respectively. The results show that the RLS algorithm has faster convergence speed than the LMS algorithm, and has less computational complexity than the SMI. In FPGA measurement, the anti-interference performance can reach about 80 dB and 70 dB respectively for single and triple broadband interferences.","PeriodicalId":166358,"journal":{"name":"2022 IEEE 5th International Conference on Electronics Technology (ICET)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123775689","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}
