How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The Resilient Modulus (M R) is an essential parameter describing the mechanical behaviour of pavement materials, but the tests to obtain it are time-consuming and costly. Therefore, machine learning, especially Artificial Neural Networks (ANN), has recently been an effective alternative for predicting M R. Although there has been an increase in art...
The deficit in sewage collection and treatment is a problem in Brazil, and a large portion of untreated sewage, usually disposed directly into water bodies, compromises water quality, with implications for public health and environmental balance. This scenario does not differ in the State of Minas Gerais, where only 44% of the urban population has...
No Brasil, em 2021, aproximadamente 59% dos estudantes matriculados em instituições de ensino superior eram mulheres. Porém, esse percentual não está homogeneamente distribuído nos cursos ofertados, sendo muito menor em cursos das áreas de Tecnologia, Engenharia e Ciências Exatas. O mesmo ocorre com a quantidade de docentes mulheres, que apesar de...
Apesar do manejo de resíduos sólidos domiciliares ser componente do saneamento básico, conforme estabelecido pela Lei Federal nº 11.445/2007, apenas 58,6% da população brasileira têm acesso adequado a esse serviço. Essa porcentagem é ainda mais alarmante para as áreas rurais, onde apenas 23,6% da população possui acesso adequado ao manejo de resídu...
Com a expansão dos cursos técnicos pelo país, novas unidades de ensino foram criadas, com cursos adaptados às necessidades locais. Porém, é preciso refletir sobre o contexto de implementação desses cursos e do seu real impacto na vida dos alunos ingressantes, assim como no grande número de alunos que evadem ou são reprovados em algum momento dessa...
We introduce two classes of multivariate log skewed distributions with normal kernel: the log canonical fundamental skew-normal (log-CFUSN) and the log unified skew-normal (log-SUN). We also discuss some properties of the log-CFUSN family of distributions. These new classes of log-skewed distributions include the log-normal and multivariate log-ske...
This article mainly focuses on studying the Shannon entropy and Kullback-Leibler divergence of the multivariate log-canonical fundamental skew-normal (LCFUSN) and canonical fundamental skew-normal (CFUSN) families of distributions, extending previous works. We relate our results with entropies of other well-known distributions. As a by-product we a...
