The theoretical part creates a spatial model of the dynamics of a multibody system using the method of Lagrange equations of motion, which takes into account the influence of the terrain and the human body. The model is experimentally verified on the 30 mm AGS-17 grenade launcher. The obtained results are the basis for evaluating the fire stability of an automatic weapon when firing in burst, which allows modernization of existing weapons, its new use by troops, such as further vehicle mounts, Navy and Coast Guard vessels, helicopters, as well as evaluation of similar weapon systems.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126940320","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}

Evaluation of geometric properties of the manufactured component is one of the critical steps before deployment of the additive manufacturing in aviation. Both micro- and macro-geometry needs to be properly assessed. This paper presents viable methods for both evaluation and assessment of the surface of the manufactured component, which is directly dependent on the parameters selected during the manufacturing. Monitored parameters were chosen based on the shape of the tested component. Selected parameter from macrogeometry is roundness and deviation of roundness from diameter. As for microgeometry, the surface roughness was explored. Considering the complex shape of the surface of the tested component, the proper parameter to describe the surface roughness had to be found as well.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123042782","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 land cover of the Kraliky county (NE of Czechia) captured by 55 orthophotos in 1953 and 2016 was classified to evaluate the long-term LC development of this peripheral region. The comparison of manual digitization, per-pixel and object-oriented classification demonstrated benefits of the last approach. The multiresolution segmentation was tuned separately for images with and without built-up areas. The object-oriented classification was focused to distinguish 5 basic classes – forest, grassland, cropland, water and built-up. To improve accuracy, the last class required a visual inspection and part reclassification. Linear features such as roads and railways were classified differently based on ancillary vector data, i.e. its visual inspection in images and modifications. The LC development of Kraliky county shows 21% increased forested area and the same level of decrease for grasslands. Built-up areas are larger by 8%, and the area of cropland remains the same despite collectivization in the 1950s. The segmentation and object-oriented classification of airborne images enabled quick statistical assessment of the long-term LC changes. Results indicate that the object-oriented classification is much more effective than manual digitization despite the possible inclusion of manual parts such as partial visual inspection and modification after object-oriented classification, and that the processing time can be reduced to half the average.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128579598","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}

Authors used the standard procedure for the preparatory phase of future scientific work. Within the pre-research, the idea of experiments was determined, which will be used for verification work procedures designed to increase the accuracy and effectiveness of a new screening system when measuring the temperature of people (e.g. airmen or passengers), reducing false positive and false negative results. Acquisition of the necessary know-how will be the subject of experiments and subsequent activities, to improve the design (hardware of thermogate, software GINA management system) of the new technical equipment of the project partner before launching the product on the market.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122760350","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}
