Desenvolvimento prático de projetos de segurança da informação no Instituto Federal de Educação de Rondônia – Campus Ariquemes / Practical development of information security projects at the Federal Institute of Education of Rondônia – Campus Ariquemes

O presente artigo relata como foram criados e executados projetos de extensão sobre temas relacionados à segurança da informação, no curso técnico em manutenção e suporte em informática, do Campus Ariquemes, do Instituto Federal de Educação, Ciência e Tecnologia de Rondônia. O objetivo foi verificar se os discentes do ensino médio técnico seriam capazes de, sobre orientação de um professor da área, elaborar e executar um projeto prático, sobre os temas, criptografia, engenharia social, SQL Injection WannaCry, dentre outros, apresentando-os e demonstrando a sua prática em uma palestra aberta à comunidade em geral. Os discentes foram alocados em grupos, onde receberam um tema específico, escreveram o projeto, aprenderam a utilizar as tecnologias pertinentes aos temas, criaram apresentações de slides e apresentaram o tema em evento do Campus, demonstrando de forma prática a sua execução, obtendo sucesso nas suas atividades

Reinforcement of Timber Beams with Steel Bars: Parametric Analysis Using the Finite Element Method

Incorporating steel bars as reinforcement in glued laminated timber beams is a technique that aims at better structural performance, allowing the reduction of cross-sections. In the present research, based on experimental results from literature about the reinforcement of timbers beams, a parametric study was carried out with the aid of 164 numerical simulations performed within the scope of linear and nonlinear physical analysis via the finite element method to evaluate, with the aid of analysis of variance (ANOVA), the span, base, height, and the reinforcement ratio influence in the service force, ultimate force, and ultimate displacement. Multiple regression models evaluated by ANOVA were established to estimate the service and ultimate forces and ultimate and service displacements as a function of other variables. The results showed an average increase in the service load of 32% and 49%, and the ultimate load of 42.90% and 66.90%, for reinforcement rates of 2% and 4%, respectively. Regarding the multiple regression models, due to the good values obtained from the adjusted determination coefficients to estimate the values of the forces and the ultimate displacements, these can be used in the pre-design of glued laminated timber beams reinforced with steel bars
