For this purpose, a mathematical model of a dual-channel piezoelectric gravimeter was used. In consequence of the carried out mathematical model modeling, the results of modeling on a computer are obtained and presented. The influence of the external disturbance parameters on a new dual-channel piezoelectric gravimeter operation was modeled. As external disturbances, the following was considered: influence of both frequencies and amplitudes of forced vibrations of the base (along longitudinal and transverse axes), on which a dual-channel piezoelectric gravimeter is located, as well as the disturbing vibration accelerations for the most unfavorable resonance cases: ω = ω 0 , ω = 2 ω 0 , ω = 3 ω 0 , 2 ω = ω 0 , 3 ω = ω 0 , where ω 0 — is the natural vibration frequency of a dual-channel piezoelectric gravimeter, ω - is the disturbances frequency. In consequence of the carried-out modeling, the graphs of the output signal change were obtained for various values of the disturbance frequency of vibration accelerations, the damping coefficient and various values of the disturbing vibration accelerations amplitudes. In view of each result and graph that have obtained, the analyzes as to the steady-state forced vibrations magnitude of a two-channel piezoelectric gravimeter as well as the conclusion concerning presence or absence of resonance were made. Using the results of previous studies of the authors, the comparison of the analytical solution of the equations of a dual-channel piezoelectric gravimeter motion, when exposed to the external disturbances was carried out with the results of digital model- ing. The analysis of the modeling results has shown that the mean root square deviation of the solutions does not exceed 0.009 mm and this analysis has confirmed the adequacy of the mathematical model of a two-channel piezoelectric gravime-ISSN ter, in other words, the obtained mathematical model of a dual-channel piezoelectric gravimeter corresponds to a real device and this model can be used for further studies of a dual-channel piezoelectric gravimeter motion parameters.","PeriodicalId":101869,"journal":{"name":"Visnyk of Vinnytsia Politechnical Institute","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126425013","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 content of fillers in biocomposite materials varied in the range of 80…130 wt. parts. This is the optimal content of particles in the biopolymer matrix. Samples formed by mechanically mixing a solution of bone glue with the processed filler. Then the resulting biocomposition pressed into a mold. Homogeneity and continuity of the biopolymer matrix is ensured by a step-by-step heat treatment of biocomposite materials. The optimal content of fillers was deter-mined by the results of analysis of experimental studies of the compressive strength of cylindrical samples. The highest values of the compressive strength (78,02 MPa) have biocomposite materials containing 190 wt. parts of particles of grain stalks. The macrostructure of the developed biocomposite materials analyzed. Biocomposite materials filled with particles of crushed dried leaves have the largest number of macroscopic defects after heat treatment. A large number of pores and cracks were found in these samples. The least number of defects have biocomposites filled with particles of crushed grains stalks, which confirmed by the obtained values of the compressive strength. The developed biocomposite materials can use for fabrication elements of furniture and floor, elements of a decor of salon of vehicles, containers and cases of devices.","PeriodicalId":101869,"journal":{"name":"Visnyk of Vinnytsia Politechnical Institute","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122568482","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 especially applies to the security and defense sector, where the availability of the necessary information support is the main requirement for the effective response of departmental bodies (relevant law enforcement agencies) to crisis situations arising both in society and the state as a whole. In connection with this, the role of video information support as a means for prompt decision-making is significantly increased. This is due to the fact that the key principles of the implementation of video information provision are timeliness (operational) and reliability. For this purpose, stationary and mobile photo and video surveillance systems are quite actively used. The use of the latter is closely related to the aviation segment — unmanned aerial vehicles and complexes, the role of which is increased by the presence of such properties as scale and mobility. However, at the same time, the following problematic factors arise related to the use of wireless communication technologies for data delivery to the final addressee: an imbalance between the ever-increasing volumes of data and the bandwidth of data transmission channels; the influence of obstacles arising in the process of video data delivery on the level of reliability of the reconstructed video image. It should be noted that the use of existing methods of interference-resistant coding to solve the above-mentioned problems leads to a significant increase in the volume of video data, which is critical in the conditions of using wireless communication technologies — video is an information resource transmitted with significant time delays. For this purpose, a method of video data reconstruction is being developed based on the use of identifiers (markers) of uneven code structures assigned to the elements of clusters formed as a result of the restructuring of the information space by structural feature. A distinctive feature of the developed method is the independent decompositional statistical decoding of individual code subsets according to structural features. This ensures, due to the use of additional service information, the localization of errors in the process of data reconstruction of the video information resource.
