The results of the synthesis of the fuzzy logic based control systems derived using MATLAB / Global Optimization Toolbox are given. As a result two approaches to the fuzzy controller synthesis have been considered: (1) with adjustable membership functions, (2) with membership functions fixed by an expert and with adjustment of input and output scale factors. It is shown that the second approach is preferable to the first, because it is simpler to implement and reduces the time required for setting the controller parameters.","PeriodicalId":293543,"journal":{"name":"2016 Dynamics of Systems, Mechanisms and Machines (Dynamics)","volume":"92 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129312197","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}

Cylinder deflections are modeled by elastic shifts of one-mass system, which parameters are found by using the method of the equivalent mass. The hydrodynamic parameters of viscous incompressible liquid layer in the channel, as well as outer channel wall shifts, are found.

We have developed a method and software that improve the efficiency of the technology of websites verification in the Internet. The software works on the principle of verification of checksums and comparison of the exemplary copy of the website owner with data located on the server to monitor and recover deleted or changed files. This method checks of infection for different files such as archives, graphics, documents and multimedia data that are not able to do the existing methods of verification. Analysis of the speed data verification of website showed that in case of the absence of infection on the server the speed of comparison of checksum is 3–4 times more than in a situation when files are missing or have been infected. In case of the absence of files on the server, the speed of testing of data is approximately equal to the speed of their direct upload to a server, i.e. the actual speed of the Internet connection. When files are infected the time of testing is increased about 1.5 times. In the case of the long-term storage of the digitized data on a WEB-server or a local network, it is recommended to use only binary method for recording of files. A method of combating viral threats for Internet resources based on the checksum shows good results and is recommended for these tasks.","PeriodicalId":293543,"journal":{"name":"2016 Dynamics of Systems, Mechanisms and Machines (Dynamics)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129429100","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}
