In the cylinder-piston group, where the greatest friction forces and loads occur, as a result, the quality of engine oil directly affects the resource of the internal combustion engine (ICE). Of no less importance is the constant presence of a reliable oil film in the contact zone of the support and connecting rod necks of the crankshaft with sliding bearings. In addition to the operating time, the parameters are influenced by external environmental factors, operating conditions and the residual life of the engine at the time of oil filling. Factors affecting the operation are important for the study of oils in order to provide information about the quality of oil and the condition of the car in conjunction with these indicators. To derive oil indicators, it is required to conduct laboratory tests using special equipment in order to give more accurate information about the quality of the engine oil under study. Purpose. Determination of the residual oil life and its effect on the mechanisms of the car engine during operation. Method or methodology of work. The article used laboratory studies using existing instruments. Results. The most informative parameters showing the residual resource of motor oils and their effect on the internal combustion engine are obtained. The scope of the results.

In most cases, you need to make several transfers to do this. The problem of choosing a path is solved by routing algorithms. The routing algorithm must have well-defined properties: reliability, correctness, stability, simplicity and optimality. The latter property is not as transparent as it may seem at first glance, it all depends on which or which parameters are optimized. This task is sometimes not at all easy even for relatively simple local networks. Optimization parameters may include minimum delivery delay, maximum throughput, minimum price, maximum reliability, or minimum error probability. In this paper, reactive, proactive and hybrid routing protocols are considered. When making their choice, we relied on the method of hierarchy analysis. Based on the results obtained during the simulation of a network with video conference traffic, a matrix was constructed for each of the criteria studied. The protocols were compared in terms of the possibility of information loss. The results of the research can be useful in the course of building modern computer networks.","PeriodicalId":53093,"journal":{"name":"International Journal of Advanced Studies","volume":"302 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334677","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 authors proposed the use of convolutional neural networks to determine the signature class. Signatures play an important role in financial, commercial and legal transactions, their recognition guarantees the security of not only information, but the whole person. The use of neural networks for signature recognition allows you to reliably identify a user in an automated mode. The authors have developed a convolutional neural network, and also proposed an algorithm that consists of image preprocessing, including background segmentation, noise reduction, and image normalization. Image preprocessing improves the quality of the network. Next, feature extraction is performed, which consists of global features, such as the ratio of the height to width of the signature, the maximum horizontal histogram and the maximum vertical histogram, the horizontal center and the vertical center of the signature, the endpoints of the signature, the signature area, training a neural network with extracted features, recognition the owner of the handwritten signature and then predicting the class of the signature. Purpose – development of a handwritten signature recognition algorithm using neural networks. Methodology: the methods of computer vision were used in the work; deep learning methods, as well as object-oriented programming methods. Results: developed a handwritten signature recognition algorithm using a neural network. Practical implications: the application of the results obtained is useful in forensic analysis of documents, since a person uses a signature on a regular basis to sign checks, legal documents, contracts and other paper media that need protection. Therefore, when someone tries to copy a signature, a problem arises that can lead to undesirable consequences in the form of theft and further use of both personal data and other valuable secret information.","PeriodicalId":53093,"journal":{"name":"International Journal of Advanced Studies","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334659","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}
