The type of certification under consideration is limited to methods and techniques for analyzing vulnerabilities and undeclared capabilities. This type of certification is intended for software research. Not all possible aspects related to this type of certification have been considered, however, the novelty and advantages of the approaches are based on some original approaches in cases where it is not clear how to present sets of input data for testing. Approaches to certification tests are presented using tools of our own design, which allows you to identify the main parameters necessary for assembling software and its research, and to parse software written in various programming languages. Based on the program of testing and verification of the object of assessment in accordance with the requirements of information security under a certain level of control, methods for conducting certification studies are proposed, the advantages of approaches using the available and proposed tools are shown. To save on the purchase of tools, some well-known, free and freely distributed tools, as well as effective and inexpensive software products, are proposed for use in tests.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88957093","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}

Individual elements were evaluated in the car. The operation of the Ponsse-ERGO harvester was carried out on the territory of the Krasnoyarsk Territory. The duration of observations was 10 500 hours. During this time, each node revealed a certain number of failures and the average recovery time after node failure. Based on the results of the calculations, a probability diagram of the harvester system states and a Pareto diagram (accumulated probability of system failures) are constructed. According to calculations, it was determined that the greatest probability of failures falls on the hydraulic system of the transmission and hydraulic manipulator. These elements of the machine account for the main load during its operation. A detailed analysis of the reasons for the failure of a logging machine during its operation is presented. It was revealed that the main reasons for the failure of the hydraulic system are: violation of the tightness of the connection pipelines, increased wear of the moving elements of the assembly, contamination of the hydraulic fluid, not always satisfactory work of the service personnel. Also, the most common reason for stopping the harvester during operation is the failure of the saw headset. An increase in the harvester’s performance and durability can be achieved by optimizing the operating conditions of the logging machine, and optimally selected design material that has higher technical characteristics that strengthen the part itself and the wear surface.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76368144","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}

Both models are based on the formalization of the state of plant species using linguistic variables that model the evaluation actions of experts in fuzzy conditions. The first model, developed earlier by the author, allows you to find the ratings of green spaces by comparing their states with each other. Thus, the resulting rating of the state of a plant species provides information about the advantages of one species over another, but does not provide complete information about the real state of green spaces. At the same time, it is possible that all plant species from the considered population, regardless of the rating, are not resistant to harmful urban environment. The second model, developed in this article, allows you to find the ratings of plant species based on their ideal state. For this, the distance between the linguistic variables that formalize the real state of a plant species and its ideal state is determined. Since the states of green spaces are compared with the ideal state, and not among themselves, the resulting rating of one plant species does not depend on the data obtained in the evaluation of other species. The developed models allow their alternative application depending on the goals and objectives.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90937405","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}

Although Pinus sylvestris L. is one of the most common species in Europe and Asia, the widespread felling of scots pine, due to the great demand for its valuable raw materials, created the need for the renewal of this breed. Artificial restoration of scots pine often occurs with the help of seeds of medium or low quality, due to the absence or shortage of high-quality raw materials. The solution to this problem can be the use of preparations that improve the quality characteristics of seeds. Therefore, the main task of our study was the impact on seeds, in order to improve their basic qualitative characteristics, of the proposed growth regulator — condensate formed during the drying of wood in the drying chamber of a woodworking enterprise. The reasons for choosing condensate were the content of a large amount of useful substances, cost-effectiveness, environmental safety of use for both humans and the environment, and ease of use. The results of the experiment showed that the germination of seeds was 97 %, and the germinative energy was 87 %. In addition, during the processing of the results of the experiment, it turned out that the substance under the study affects the ability of the seeds treated with it to resist rotting. The protective properties of the condensate are indicated by an insignificant amount of rotted seeds, which ranges from 0 to 1 %. Another weighty argument in favor of the use of condensate seeds for growth stimulation is the waste-free production which is undoubtedly an urgent direction today.","PeriodicalId":12343,"journal":{"name":"Forestry Bulletin","volume":"44 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91441693","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}
