1. New Proposal to Calculate the Friction in Sheet Metal Forming Through Bending Under Tension Test
There are 6 different types of equations that have been formulated to measure friction through the bending under tension test, however, there is no work to show whether these calculations actually represent what is happening in a sheet metal stamping process. This paper aims to make a direct comparison between the bending under tension test and the sheet met

2. Efecto del tiempo de superpulso de soldadura sobre la evolución microestructural de un acero de bajo carbono
ABSTRACT The Super Pulse arc type was developed to provide a solution to butt root pass beads in the semi-automatic welding process with gas protection (GMAW). Unlike standard pulse welding, the Super Pulse uses a sequence of different pulse waveforms to create a cord shape and appearance similar to the GTAW process. It uses higher amperage in the primary ph

3. Morphology and stratigraphy of Serra Geral silicic lava flows in the northern segment of the Torres Trough, Paraná Igneous Province
ABSTRACT: The impetus for this research was the enigma regarding the origin of the extensive silicic volcanic units in the Paraná-Etendeka Igneous Province. Are they rheoignimbrites, lava flows, or a combination of both? The São Joaquim silicic eruptive sequence is comprised of Palmas-Type aphyric dacites and is located in the northern segment of Torres Tr

6. Efecto de los parámetros de soldadura sobre la microestructura de recargues nanoestructurados base hierro depositados por FCAW-S
Lately modern hardfacing tubular wires for semiautomatic welding with gas protection and without it have been developed. These wires deposit Fe-based nanostructured alloys with high abrasive wear resistance. The information on these new consumables is scarce, especially about the effect that the welding parameters (heat input, shielding gas, arc voltage, cur

7. A maximum margin-based kernel width estimator and its application to the response to neoadjuvant chemotherapy
INTRODUCTION: Function induction problems are frequently represented by affinity measures between the elements of the inductive sample set, and kernel matrices are a well-known example of affinity measures. METHODS: The objective of the present work is to obtain information about the relations between data from a calculated kernel matrix by initially assumin

8. Desenvolvimento de um ambiente para simulação da manufatura baseado em features e realidade virtual / Development of environment for simulation of manufacturing based on features and virtual reality
Nowadays with the diversification of products demanded, manufacturing systems have become increasingly complex and with difficult operation. Hardly the person responsible for the manufacturing area has all the information necessary to anticipate the details for their implementation. On the other hand, companies don\ t have the time or resources to test alter

10. Avaliação de diferentes ferramentas no torneamento da liga Inconel 713C / Evaluation of different tools in turning of Inconel 713C
The super alloy Inconel 713C is an alloy whose main element of its composition is nickel. The combination of high levels of this element and the structure of this material makes it very difficult to be transformed by the machining process. Because of this difficulty and lack of information about the machining of this material, the purpose of this study was t

12. Sistemas dinâmicos de eventos discretos com aplicação ao fluxo geodésico em superfícies hiperbólicas / Discrete event dynamical systems with application to the geodesic flow on hyperbolic surfaces
Neste trabalho apresentamos um método de descrição combinatorial para o fluxo geodesico sobre uma região hiperbólica compacta, tendo como objetivo associar a seqüências de codificação, parâmetros topologicos oriundos destas superfícies. Isto permite conjugar conceitos topologicos e combinatoriais oriundos das superfícies estudadas com conceitos d
