In this respect, 7 different types of knitted fabrics that are made of different raw materials, and have different fabric constructions and yarn numbers were planned to use in the production of cosmetic textile products. Firstly, trial productions of these fabrics were done and performance tests were carried out. After determination of the appropriate fabric type by performance tests, suggestions were given about proper end usage and final product according to the chosen fabric.","PeriodicalId":10543,"journal":{"name":"Contemporary engineering sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77126474","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}

Como objetivo realizou-se uma análise comparativa entre os métodos de dimensionamento de pavimentos, o empírico atualmente empregado pelo Departamento Nacional de Infraestrutura e Transportes (DNIT) e o método mecanístico-empírico de Dimensionamento Nacional de Pavimentos (MEDINA), a fim de elucidar o uso do método mecanístico-empírico. Com a finalidade de comparar o dimensionamento das camadas de base e sub-base de pavimentos flexíveis, por meio dos diferentes métodos, sendo adotado o método empírico que tem como fundamento os dados de CBR, empregado pelo DNIT e o mecanístico-emprírico (Medina) com base em conceitos da teoria da elasticidade. Para cálculo das espessuras das camadas do pavimento flexível, foram propostos dois volumes de tráfego diferentes. Os dados dos materiais que foram utilizados nas camadas de base e sub-base foram obtidos a partir de estudos bibliográficos prévios. Na sequência foi realizado o dimensionamento do pavimento com os dois métodos propostos. Dentre os resultados obtidos, observa-se que Medina permite maiores análises e variações de materiais de revestimento, com base nas propriedades dos materiais. Para as possibilidades analisadas, destaca-se o tipo de material utilizado na camada do revestimento influenciando consideravelmente em sua espessura, fator relacionado ao módulo resiliente desses materiais, ou seja, para os casos propostos a espessura da camada de revestimento foi menor quanto maior foi o MR do revestimento adotado. O resultado que mais se destacou foi no caso 2.2 em que o revestimento foi de concretos betuminoso com 7,5cm de espessura no método empírico e pelo método mecanístico-empírico concreto asfáltico de classe 4 com 9,4cm manifestou melhores resultados para as camadas de revestimento, atendendo aos padrões de dimensionamento do programa. Ressalta-se que o dimensionamento efetuado pelo novo método colabora com a viabilidade a longo prazo e o pavimento tende a alcançar seu tempo de vida útil com maior segurança e economicidade, comparado ao método empírico.","PeriodicalId":10543,"journal":{"name":"Contemporary engineering sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82449600","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}

Industry 4.0 transforms the economy through “de-structive” technologies and new risks. It is requiring update of the views and the dealing with uncertain environment. The goal of this paper is to summarize the mainly used risk management standards, to analyze the general aspects of evolution of risk management, enterprise risk management, enterprise integrated risk management and to suggest the concept for the next step which is enterprise global risk management, where are implemented Industry 4.0 risk and Artificial Intelligence. The proposed concept considers organizational-hierarchical structure of the enterprise as complex, the risk management policy as global, the respective actions as permanent and the orientation toward risks as adaptive. It is determent the future development in connection with enterprise resource planning.","PeriodicalId":10543,"journal":{"name":"Contemporary engineering sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79940588","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}
