The oxidation process is more advantageous than bromination. Free active centers, even that on the oxidized surface, maintain their ability to the bromine addition reaction. However, the probability of their existence on the oxidized surface is very low.

In this case, the energy capabilities of transceiver underwater acoustic means can be reduced due to refractive circumstances in the information channel. In addition, work in shallow areas occurs under conditions of dispersion, one of the consequences of which is the deformation of communication signals during propagation in the information channel. The most sensitive parameters of the transmitted message to external destructive effects are: its envelope, duration and frequency composition. The aim of the work is to determine the effects of correcting the energy range in a shallow sea with an acoustically hard bottom of underwater communication systems. The relevance of the work is necessary in rapid development of underwater robotics for studying the oceans. The current progress in underwater communications means shows that it is useful to use energy factors that additionally affect not only the quality of transmission of the message through the communication channel, but also the energy range of the message transmission, the detection of the noise field of the subscriber or the search object. These include the formation in the working space of the water area of singular points corresponding to the “vortex” and “saddle” classes. The results of the work should include clarification of the issue of the mutual influence of the intensity distributions and impedance characteristics along the waveguide length, as well as the conditions for local interruption of communication with the subscriber as a factor in limiting the energy range of underwater communications.","PeriodicalId":210314,"journal":{"name":"2020 IEEE 40th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131367000","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}

An alternative approach to the principle of data transfer based on existing equipment is formulated. The requirements for the simulator for modeling the process of data transfer are formulated. Models of coding and decoding blocks are proposed. The possibility of modeling the effect of interference in the Matlab system at a logical level is investigated. The content of an alternative approach to data transmission consists in replacing an information bit with a logical vector. The logical convolution of the direct and mirror logical vector is carried out on the receiving side. The convolution operation is performed by software without the use of analog-to-digital conversion of the received signal. The advantage of the proposed principle of redundancy of information is that the implementation is feasible for both cable and Internet television. In the latter case, a positive effect is achieved when there is free traffic. The application of this approach for cable television is justified in the presence of free carriers (subcarriers). This proposal is also of interest for technical television systems operating in the conditions of interference, for which the reliability of data transmission takes precedence over other parameters.","PeriodicalId":210314,"journal":{"name":"2020 IEEE 40th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124291845","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 comparison results show that the proposed topologies perform better using quasi-sinusoidal modulation technique. The interleaved quasi-switched boost inverter topology has the advantage of reduced passive components with higher output power compared to interleaved quasi-z-source inverter topology.

Thus, the switching frequency can be selected depending on the required output parameters of the converter. A comparative analysis of EMI for efficiency 0.93-0.94 of the half-bridge converters with GaN and Si transistors is performed.

Lossy compression is mostly employed for this purpose and an important task for it is to find and provide an appropriate compromise between compression ratio and quality of compressed data, in the first order, image visual quality. This paper considers an approach to predicting visual quality characterized by the metrics MSEHVSM or, equivalently, PSNR-HVS-M for the coder AGU based on discrete cosine transform (DCT). It is demonstrated that it is possible to estimate MSEHVSM in a limited number of 8×8 pixel blocks and then to predict this metric for the entire image for the considered coder. The influence of image content and the number of analyzed blocks is studied. It is shown that 500 or 1000 blocks are usually enough to carry out prediction with appropriate accuracy.","PeriodicalId":210314,"journal":{"name":"2020 IEEE 40th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130309921","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}
