With the utilization of artificial intelligence, these systems can even compose an online attendance register of students present during the lectures. Data is primarily recorded on the hard disk of the NVR (Network Video Recorder), and in the long term, it is recommended to save the data in the blockchain. The purpose of the research is to demonstrate how university security cameras can be securely connected to the blockchain. This would be important for universities as this is sensitive student data that needs to be protected from unauthorized access. In my research, as part of the practical implementation, I therefore also use encryption methods and data fragmentation, which are saved at the nodes of the blockchain. Thus, even a DDoS (Distributed Denial of Service) type attack may be easily repelled, as data is not concentrated on a single, central server. To further increase security, it is useful to constitute a blockchain capable of its own data storage at the faculty itself, rather than renting data storage space, so we, ourselves may regulate the conditions of operation, and the policy of data protection. As a practical part of my research, therefore, I created a blockchain called UEDSC (Universities Data Storage Chain) where I saved the student's data.","PeriodicalId":18535,"journal":{"name":"Micro","volume":"55 1","pages":"000185-000190"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89086026","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}

It is determined by the “physics” of the system to be controlled. In finite time-resolution approach the digital controllers model the derivatives by finite differences, and the simplest numerical integration via Euler’s method also uses such differences. Whenever some fractional order derivative of the tracking error is fed back, this long memory term allows the realization of such control strategies for various integer order systems by appropriately masking” and weighting certain elements of longer sequences. On this mathematical basis the idea of controlling a higher order system by the application of a lower order strategy can be formulated, too. The main benefit may be achieving monotonic decrease in the components of the tracking error. In this paper the first order control of a popular second order system often used for benchmark applications, the van der Pol oscillator is considered. The realization of a simple proportional feedback first order controller in two variants, and a PID-type Computed Torque Control are considered in the fixed point iteration-based adaptive framework to tackle the problems caused by modeling imprecisions. The applicability and the limits of the investigated approaches are concluded.","PeriodicalId":18535,"journal":{"name":"Micro","volume":"28 1","pages":"000119-000124"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73183427","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}
