Garments for persons with special needs are part of the functional clothing category and are meant to improve the quality of life of those whose body shape, mobility or dexterity differs from the norms. Virtual prototyping of garments provides high potential for design, product development and marketing processes. This paper presents the virtual prototyping of functional knitted garments for persons with special needs (elderly people, people with disabilities, operational staff from defense/public order/security structures) highlighting the importance of personalization and its competitive advantages. The steps to develop the virtual prototypes were: i) 2D pattern design from data in the dimensional table of the model and in correlation with the real sizes of knitted garments using Pattern Design Software (PDS) from OPTITEX; ii) Simulation knitted garments prototypes on the avatar using Optitex 3D Suite Software; iii) Evaluating the fit of the product on the body. The possibility to check the aspect of the product and how it is matching on the 3D model of the human body, without requiring physical development of a prototype is the main advantage of the virtual prototypes. If the product does not fit properly on the 3D surface of 3D model (mannequin / avatar), the designer can easily modify the shapes of parts and then check the new shape by repeating the steps of 3D simulation process in virtual space.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128104571","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 also a field where robotic navigation, route optimization and precise maneuvering are crucial to the competitiveness of the engineering product on the market. This research demonstrates a mathematical modeling method through which robots can navigate warehouse floors efficiently, using indoor positioning of high accuracy. Moreover, the paper also describes the hardware considerations taken into account when measuring the accuracy of the robot from achieving its destination on the floor plan. A prototype is creating, showing the sensor fusion interlinks for obstacle avoidance and distance mapping. Finally, the prototype and the algorithm are tested against eight static, as well as dynamic performance tests, in order to validate the performance of the system in static and dynamic interference environments. The goal of this paper is to present the engineering perspectives of optimizing a self-driving warehouse robot through utilization of the emerging technologies related to indoor positioning. This is presented through a prototype development of an Automated Guided Vehicle which will perform indoor positioning of itself across a warehouse floor plan and be able to avoid obstacles while driving towards its destination. Both the hardware description and the algorithmic modeling will be presented, accompanied by an extensive set of testing experiments, presented to determine the feasibility of our proposed developments in this field.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115901431","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}

However, there is not much information on the effect of laser energy on the leather structure during finishing, so additional research is need. Crust leather produced by a new unified resource-saving technology with the use of polymer compounds at the stage of tanning and liquid finishing was used for research. The different leather samples were taken for research the laser effect. Leather samples with a thickness of 1.40-1.45 mm were subjected to laser engraving at a depth of laser ablation from 0.1 mm to 0.7 mm in steps of 0.1 mm. It was found that the structure of the dermis under the action of laser radiation has not undergone morphological changes: the samples preserved the natural histological structure, collagen bundles are not deformed, the layers are evenly spaced without increasing the density of the structure. There is some increase in the distances between the structural elements of the dermis. It was found in the area of direct action of the laser beam there are signs of welding of collagen fibers, but on the surface of the sample of leather were no found chemicals substance. The influence of laser finishing on the structure and physical-mechanical properties of leather for footwear and leather goods was determined. It was found that increasing the depth of ablation to 50-52% of the thickness of the leather adversely affects it`s physical and mechanical properties, thereby deteriorating the performance of footwear and leather goods. The results of complex research of the effect of laser radiation on the physical and mechanical properties of the leather for the shoes uppers and leather goods allowed to establish rational technological parameters of the laser finish. Such information expands the possibilities of introducing laser equipment into serial production in order to create a modern range of finished products due to the creative design of models and unification of products.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121634873","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}

Shielding solution of Electromagnetic Compatibility domain is tackled nowadays by modern manufacturing methods of flexible textile fabrics with electrically conductive properties. Our research focuses on the additional electromagnetic shielding effectiveness (EMSE) rendered by plasma coating of flexible woven fabrics with inserted conductive yarns. EMSE was computed for an experimental plan formed of plasma coating with Copper and Stainless steel with thicknesses of 400 nm and 1200 nm on both sides of woven fabrics with inserted conductive yarns of stainless steel and silver. An additional EMSE of 5-20 dB on the frequency range of 0.1-1000 MHz was achieved by plasma coating. This proves the enhancement of the shielding properties by magnetron plasma coating, without altering the bulk properties of textile fabrics, such as flexibility and mechanical resistance. The paper presents EMSE results in relation to fabric structure, raw metallic materials and frequency of the incident electromagnetic field.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117253261","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}

In order to overcome the increasing drug resistance globally, a wide variety of studies are carried out on probiotic microorganisms. In this study, we aimed to investigate the synergistic activities of the bioactive components of L. casei and S. thermophilus probiotic microorganisms against ESBL-positive E. coli and K. pneumoniae strains against these two microorganisms. The non-toxic concentrations of L. casei and S. thermophilus bioactive components in Vero cell culture were determined. Antibacterial activities against ESBL-positive E. coli and K. pneumoniae at determined non-toxic concentrations were evaluated by studying MIC and MBC concentrations. Firstly, non-cytotoxic concentrations of bioactive metabolites of S. thermophilus and L. casei were determined on Vero cells. It has been determined that the bioactive metabolites of both S. thermophilus and L. casei cause toxicity of <32 µg/ml. For this reason, studies have been studied at levels lower than this concentration for antimicrobial efficacy studies. Antimicrobial activities of L. casei and S. thermophilus alone and in combination against E. coli were given. Here, it was determined that the activities of probiotic microorganisms created a synergistic effect when used in combination. It was determined that the activities of L. casei and S. thermophilus, when used in combination, had a synergistic effect against K. pneumoniae. In this study, where we aimed to produce a new and effective drug/solution in the treatment of wounds infected with drug-resistant bacteria (E. coli and K. pneumoniae), which are very difficult to treat, our findings may be hopeful.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115228994","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}

Enzymes have gained more recognition because of their properties, such as specific activity, simple application, mild enzymatic reaction conditions, and non-polluting effluent generations. However, not all enzymatic operations are well investigated, and there is still a lack of knowledge on ferment usage in post-tanning processes. The aim of this study was to investigate the enzyme implementation in wet blue bating and its effect on semi-finished product. The various enzyme preparations were used for bating at different concentrations and process times. The amount of removed collagen proteins, the shrinkage temperature after bating and rechroming were assessed; on top of that, the amount of chrome compounds in semi-finished product and in the effluent was determined. The results showed that enzymatic bating had an effect on wet blue leather. The greatest difference was obtained using Zime SB enzyme preparation. The results obtained during the study are promising, even so, further research on mechanical properties, dying, and fatliquoring effects needs to be investigated to see enzymatic effect on the finished product.","PeriodicalId":196278,"journal":{"name":"Proceedings of the 9th International Conference on Advanced Materials and Systems","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134556731","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}
