1. Optimized dimensioning of steel-concrete composite beams
Resumo As seções mistas de aço e concreto estão cada vez mais sendo utilizadas na construção civil, tanto no cenário mundial quanto no Brasil. O trabalho conjunto do perfil de aço e da laje de concreto aumenta consideravelmente o desempenho do elemento estrutural misto devido ao aproveitamento das vantagens de cada material. Neste trabalho, é utiliz

2. On the Decreasing Flexural Modulus of Glass/Vinylester Composite Beams Up to Failure State
Abstract The comparison of the failure state for composite laminates under bending and tensile loads is a well-known issue which has been intensively discussed in the literature. The scope of the current work is to investigate the appropriate method of the flexural modulus of the composite laminates by the aid of experimental and numerical approach. The prim

3. Effect of shaping methods on the mechanical properties of Al-SiC composite
Al-SiC composites were successfully produced with improved mechanical properties. Effect of SiC content, its particles size and shaping method were investigated. Three shaping methods of conventional powder metallurgy (PM), hot press (HP) and hot extrusion (EX) were used. The hardness of the samples was measured by Vickers method. Tensile and compression tes

4. Tuning of multivariable decentralized controllers through the ultimate-point method
A successful method for tuning single-loop PID controllers is the ultimate-point method. This method is based on the identification of the ultimate point of the process’ frequency response followed by its shifting, through appropriate choices of the controller’s parameters, to a specified location of the complex plane. This paper presents an extension of

5. Sintonia de controladores PID descentralizados baseada no método do ponto crítico
Controladores PID são largamente utilizados no controle de processos industriais, tanto em sistemas monovariáveis como em sistemas multivariáveis. No entanto, muitos dos controladores encontrados na indústria são mal sintonizados. Um dos métodos mais simples de sintonia de controladores PID consiste em identificar algumas grandezas, as quais se relacio

6. Refino de grão de aluminio comercial por injeção de gases inertes
The transformation of any grain refining method into an useful process one depends on getting through a long chain of factors which begins with the scientific building of the technical body and finishes up with industrial, marketing and other else profitable factors. From the scientific and technologycal point view, this work is searching to give rise to thi
