Writing errors on e-essay exams reduce scores. Thus, detecting and correcting errors automatically in writing answers is necessary. The implementation of Levenshtein Distance and N-Gram can detect writing errors. However, this process needed a long time b... see more

Structural elements made of heterogeneous natural and artificial materials are widely used in the construction of modern building complexes and in many other areas. Among them is the use of boards and shells of different configurations. Currently, one of ... see more

Fluid conveyance pipes are subject to vibration and the attendant dynamic stresses lead to instability and sometimes failure. The fluid inside the pipe dynamically interacts with the motion of the pipe, therefore, the material properties of the fluid are ... see more

This research dealt with the linear elastic behavior of hollow core slabs resting on a linear Winkler type foundation. A finite difference method was used to model the slabs as wide beams and the foundation as elastic springs. The finite element method wa... see more

A estatística Cp de Mallows pode ser utilizada na seleção de melhores subconjuntos na modelagem hidrológica, principalmente nos casos em que são utilizadas muitas variáveis. Com base no fato de que há, em muitos casos, o interesse em estimar a precipitaçã... see more

In the process of analyzing prestressed sleepers for turnout on elastic foundations with large lengths, authors around the world often use the one-stiffness model of Winkler or the two-stiffness model of the Filonenko-Borodich and Pasternak. Railway bed s... see more

The paper introduces the phenomenon of fluidization as a process. Fluidization occurs when a fluid (liquid or gas) is pushed upwards through a bed of granular material. This may make the granular material to behave like a liquid and, for example, keep a l... see more
