To address the problem that the classical spatial spectrum estimation algorithm does not have high resolution for the estimation of coherent sources, a DOA estimation method based on the Witch function and normalization of variable-step-size LMS algorithm is proposed in this paper. By defining the reciprocal of the array pattern as the spatial spectrum, the proposed method regards the DOA estimation as a peak search. The simulation results show that the proposed method can effectively suppress the interference of multipath signals. And it has similar performance with the classical spatial spectrum estimation method. Compared with other beamforming methods, the proposed method has convergence speed and better stead-state performance.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127085388","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 traditional jamming situation generation method does not work well when the sampling points are sparse and the sample size is small. When the space-air platform moves at a high speed and the jamming source moves at a high speed, the sampled data has the problem of incompatibility of temporal and spatial characteristics. In order to solve these problems, this paper proposes a method of generating jamming situation based on Newton's law of cooling. Using this method, situation information in different time domains and different airspaces can be superimposed, and the jamming situation generation capability of the space-air network composed of relay satellites and drone clusters can be significantly improved. Through simulation experiments, the method proposed in this paper has obvious advantages in sensing range and sensing accuracy compared with traditional jamming situation generation methods.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":" 31","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113950902","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}

However, anti-obfuscation tools such as PowerShellProfiler and CyberChef also developed rapidly. In order to improve the security of scripts, this paper proposes a PowerShell obfuscation technology based on abstract syntax tree transformation. Firstly, this technology performs the equivalent replacement of the grammatical structure in the script. In addition, it also changes the sequence of the child nodes of the abstract syntax tree. Finally,it obfuscates the PSToken in the script. Thus, this technology can make up for the defects of the traditional obfuscation technology, and hide the program logic better to improve the concealment of the script. The experimental results show that the use of this technology proposed in this paper can improve the strength of obfuscation over 82.7% on average, which is 16% higher than traditional obfuscation technology. Moreover, this method is more effective against anti-obfuscation tools.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"41 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114045214","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}

Their functions are relatively single, which can not fully reflect the advantages of “intelligence”, and they are not real intelligent windows. Therefore, in view of this problem, a new type of intelligent window was designed. The design of the window includes the structure design and the control system design based on STM32 MCU. At the same time, the key technology of tracking the sun light and reflecting the sunlight into the room was studied. The angle relationships between the outgoing light and the rotation axis of the mirror louver, the plane of the louver, the incident light and the outgoing light were determined. According to these relationships, the angle of the louver was controlled and adjusted, so as to reflect the outdoor sunlight into the room. Finally, it can realize four functions, such as opening and closing automatically, rain proof, inducing wind and improving indoor lighting, so that it can become a real intelligent window.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117197637","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}

Especially when used in VSC-HVDC equipments, FRD chips need to be operated at high current change rate. Hence, an optimization scheme for the high resistance zone is proposed in this paper. By setting up three simulation models, the effects of high resistance zone width and doping concentration on reverse recovery performance of FRDs are studied. The high resistance zone structure effectively enhances the toleration of FRD chip to voltage stress, current stress and di/dt stress during reverse recovery. The maximum junction temperature of optimized FRD with high resistance zone increases only 188K, under the condition of 2500 V, 400A, 2500A/µs, which is better than that of conventional FRD. And the RRSOA limit is improved to 2900V, 450A, 3000A/µs. The 3.3kV FRD chips are prepared according to the optimized simulation model. After 12 chips are packaged in parallel, the reverse recovery test of 2800 V, 3200A, 7348A/µs conditions is passed, and the robustness of the FRD device is greatly improved. The actually prepared fast recovery diodes have an outstanding improvement to the reverse recovery safe operation area, and the theoretical simulation and the practical test are unified.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131737433","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}
