1. Effect of temperature gradients on the behaviour of jointed plain concrete pavements
Resumo Em muitos países da América Latina os pavimentos de concreto com juntas (JPCP) são calculados usando os métodos da “American Association of State Highway and Transportation Officials (AASHTO) ou da “Portland Cement Association” (PCA), os quais não levam em consideração explicitamente as condições climáticas específicas de cada região

2. Crashworthiness Analysis and Evaluation of Fuselage Section with Sub-floor Composite Sinusoidal Specimens
Abstract Crashworthiness is one of the main concerns in civil aviation safety particularly with regard to the increasing ratio of carbon fiber reinforced plastic (CFRP) in aircraft primary structures. In order to generate dates for model validations, the mechanical properties of T700/3234 were obtained by material performance tests, and energy-absorbing resu

3. Calculation of Aircraft Target's Single-Pulse Detection Probability
ABSTRACT: The original radar cross section data or some rough models are often used to estimate a given aircraft target detection probability. The calculation results may not be very accurate as targets are different from one another and the real radar detection process is complex. A new method for radar cross section model generation is proposed and it take

4. Dimensions and refractive index estimates of deeply buried optical waveguides in Lithium Fluoride
A recursive procedure is applied to the measured near-field profiles of buried optical waveguides recorded in a lithium fluoride (LiF) crystal by femtosecond laser pulses in order to estimate the core dimensions and the refractive index increase. Albeit the waveguides transversal section geometry is quite complex it is possible to obtain the horizontal and v

5. A new metamodel for reinforced panels under compressive loads and its application to the fuselage conception
This work presents a new metamodel for reinforced panels under compressive loads, typically used in light-weight aircraft structures. The metamodel represents a replicable cell structure of integrally machined panels. The presented formulation for conception is based on the synthesis of four stability criteria: section crippling, web buckling, flange bucklin

6. Continuidad y cambios en una vieja democracia de partidos: Uruguay (1910-2010)
This article "revisits" the old Uruguayan party democracy - the eldest and one of the few in Latin America-reviewing wellknown contributions as well as my own proposals, to point out persistence and changes during the last century. Trying to avoid "exceptionalism", the text interweaves comparative references, which provide a framework for the originality of

7. Uncertainty quantification of aircraft modal analysis using perturbation technique in the stochastic finite element method
Structural members, such as, stiffeners are applied to aeronautical structures in order to promote the necessary global or local dynamic stiffness. The manufacture and assembly process of these parts and machines capability can introduce variability in the parts and thereby incorporating uncertainties in the structural performance. Tolerances known as GD&T (

8. Análise do comportamento eletroaeroelástico de uma seção típica para geração piezelétrica de energia / Electroaeroelastic behavior analysis of a typical section for piezoelectric energy harvesting
Converting aeroelastic vibrations into electricity for low power generation has received growing attention over the past few years. In addition to potential applications for aerospace structures, the goal is to develop alternative and scalable configurations for wind energy harvesting to use in wireless electronic systems. The use of a typical airfoil sectio

9. The interpretation of the figure of the prophet Jonah by Michelangelo on the ceiling of the sistine chapel: anatomical urological vision
PURPOSE:A detailed analysis in the iconography and pictorial appearance of the scene of the "Prophet Jonah" painted by the artist Michelangelo Buonarroti (1475-1564) on the ceiling of the Sistine Chapel between the years 1508 and 1512. MATERIALS AND METHODS:Literature review on the Italian Renaissance period and the life of Michelangelo Buonarroti and analys

10. Indoor Radar Cross Section Measurements of Simple Targets
Abstract: This paper has described the radar absorbing materials characterization and radar cross section measurements, in the frequencyrange of 8 to 12 GHz, using a very simple setup. Simple targets like sphere, cylinder, flatplate, and dihedral comer were characterized by measuring the backscattered radiation patterns when these targets were illuminated by

11. Understory structure in riparian fragments of atlantic rainforest in the extreme north of Pernambuco, Brazil / Estrutura do sub-bosque em fragmentos ripÃrios na floresta atlÃntica do extremo norte, Pernambuco, Brasil
Deleterious changes in fragments of forest communities have been often associated to biotic and abiotic changes related to area and edge effects. The understory is an important component of forest communities and exhibits a clear response to the process of fragmentation, due to its susceptibility to such effects. In the Northern section of the Atlantic Fores

12. Virtual boundary method applied to a problem of computational aerolastic analysis / Método da fronteira virtual aplicado em um problema de análise aeroelástica computacional
The behavior study of a profile of a typical aerolastic section, with Reynolds in range of micro aerial vehicle, is the main focus of this work, taking as objective the estimation of parameters of flutter phenomenon. The research analyzes of the flow of a incompressible fluid on a body (cylinder and airfoil profile) at steady state and oscillating with const
