38. Dynamics of rotating non-linear thin-walled composite beams: analysis of modeling uncertainties
In this article a non-linear model for dynamic analysis of rotating thin-walled composite beams is introduced. The theory is deduced in the context of classic variational principles and the finite element method is employed to discretize and furnish a numerical approximation to the motion equations. The model considers shear flexibility as well as non-linear

39. Simulação computacional em camisas de motor construídas em liga de alumínio silício
Automotive cylinder liners are mechanical components with the function of internal coating of the cylinder automotive engines. The liners have been made of cast iron, which meets the necessary requirements. The replacement of parts made of steel/ cast iron in aluminum alloys has been made with advantages not only in reducing weight as well as fuel consumptio

40. INTERAÇÃO SOLO-ESTRUTURA DE EDIFÍCIOS COM FUNDAÇÕES SUPERFICIAIS / SOIL-STRUCTURE INTERACTION OF BUILDINGS ON SHALLOW FOUNDATIONS
This work deals with the consideration of Soil-Structure Interaction (SSI) in structural design of reinforced concrete buildings on shallow foundations of the isolated footing type. It carried out a comprehensive review on the major works done in the area and the methods for obtaining parameters and variables involved in the analysis. Numerical examples were

41. A confiança e a satisfação como mediadoras no varejo multicanal.
This study investigated the rules of the satisfaction and trust as mediating variables of the relationships between attitudes, future intentions and loyalty of consumers on multichannel retailing. Based upon the studies of Garbarino and Johnson (1999), which postulates that for relational consumers trust is the mediating variable between the attitudes and th

42. Hope, risk perception and propensity to indebtedness
Hope is an important construct in marketing, once it is an antecedent of important marketing variables, such as trust, expectation and satisfaction (MacInnis & de Mello, 2005, Almeida, Mazzon & Botelho, 2007). Specifically, the literature suggests that hope can play an important influence on risk perception (Almeida, 2010, Almeida et al., 2007, Fleming, 2008

43. Respostas estruturais em pavimentos flexíveis via utilização de equações de módulos de resiliência de solos de subleito e da camada de reforço / Structural responses in flexible pavements using equations of modules resilience of soil subgrade and the reinforcement layer
Este trabalho teve por objetivo analisar o comportamento resiliente de três solos típicos da região de Viçosa-MG, quando supostamente empregados no subleito e na camada de reforço de um pavimento flexível hipotético. Para cumprir esta finalidade, foram realizados os seguintes ensaios: caracterização geotécnica, compactação, empregando-se as energ

44. The relationship between manufacturing integration and performance from an activity-oriented perspective
Manufacturing integration with other functional areas and suppliers is a key aspect for achieving sustainable competitive advantage. The objective of this study is to analyze manufacturing integration from an activity-based perspective. We hypothesize that manufacturing integration with suppliers, marketing, and R&D is positively related to profit and sales

45. Self-Tuning Multimodal Piezoelectric Shunt Damping
Piezoelectric shunt damping is a well known structural vibration control technique that consists in connecting an electrical circuit to a piezoelectric transducer attached to the structure. In the case of a resonant shunt, the network consisting of an inductor-resistor network when combined with the capacitive nature of the piezoelectric transducer impedance

46. An extension of coupled beam method and its application to study ship's hull-superstructure interaction problems
This paper describes an extended formulation for the coupled beam method (CBM). The method is originally developed for elastic bending response analysis of passenger ships with large multi-deck superstructures. The extension is mainly performed to enable the available method in order to study elastic bending behaviour of ships fitted with superstructures of

47. Parametric analysis of a phenomenological model for vortex-induced motions of monocolumn platforms
Phenomenological models are an important branch in VIV (Vortex-Induced Vibrations) and in VIM (Vortex-Induced Motions) studies to complement the results achieved via CFD (Computational Fluid Dynamics), as the latter tool is not presently a suitable tool for intense use in engineering analysis, due to high computer power requirements. A phenomenological model

48. A vision of Orkut's users: studying this phenomenon through cognitive absorption
This study aims to identify the influence that Cognitive Absorption has on the intention of using Orkut. It happens due to the fact that Cognitive Absorption is related to the state of deep involvement users carry with an individual task, performed with the support of Information Technology (IT); it corroborates the study on this virtual community. Therefore
