26. Análise de tensões e critérios de falha para juntas de estruturas aeronáuticas metálicas coladas / Stress analysis and failure criteria of metallic bonded joints in aeronautical structures
A aplicação de adesivos para união de materiais cresceu consideravelmente no decorrer dos últimos anos, sendo que tal crescimento se deve aos benefícios proporcionados pelos adesivos, quando comparados aos métodos tradicionais de união, como solda ou utilização de parafusos. Na indústria, características como fácil aplicabilidade, melhor distribu

27. Desenvolvimento de um algoritmo para identificação e caracterização de cavidades em regiões específicas de estruturas tridimensionais de proteínas / Development of an algorithm to identify and characterize cavities in specific regions of three-dimensional structures of proteins.
The identification and characterization of geometrical and physical-chemical properties in protein vacant spaces aggregates important information for steering rational drug designing and functional characterization of binding and catalytic sites. Therefore, several softwares have been develop during the past two decades in order to perform such characterizat

28. Study of bond behavior between reinforced bar and concrete with epoxi resin. / Estudo da aderência de barras de aço coladas ao concreto com resina Epóxi.
Just like others fields of knowledge, the civil construction is evolving. Hughes investments and the need for new projects improve the speed and the technology usually applied for basic infrastructures development. These scenarios achieve issues as the miss understanding of the behavior of this technological advances in long terms, caused by the few studies

29. A FEM-BEM interactive coupling for modeling the piezoelectric health monitoring systems
In this research, finite element and boundary element methods are coupled together to model the interaction of a piezoelectric ceramic working as an actuator with an elastic material. Piezoelectric-elastic material's interaction occurs in smart structures. This work is aimed at determining the actuation effects being transferred from the actuators to the hos

30. Lateral strength force of URM structures based on a constitutive model for interface element
This paper presents the numerical implementation of a new proposed interface model for modeling the behavior of mortar joints in masonry walls. Its theoretical framework is fully based on the plasticity theory. The Von Mises criterion is used to simulate the behavior of brick and stone units. The interface laws for contact elements are formulated to simulate

31. Analysis of binding properties and specificity through identification of the interface forming residues (IFR) for serine proteases in silico docked to different inhibitors.
Background: Enzymes belonging to the same super family of proteins in general operate on variety of substrates and are inhibited by wide selection of inhibitors. In this work our main objective was to expand the scope of studies that consider only the catalytic and binding pocket amino acids while analyzing enzyme specificity and instead, include a wider cat

32. Sobre o acoplamento fluido-casca utilizando o método dos elementos finitos / On fluid-shell coupling using the finite element method
This work consists of the development of computational tools for nonlinear geometric fluid-shell interaction analysis using the Finite Element Method (FEM). The fluid solver is explicit and its time integration based on characteristics. The computational code is able to simulate the Navier-Stokes equations for compressible flows written in the Eulerian descr

34. Interfaces físicas entre os sistemas prediais hidráulicos e sanitários (SPHS), estruturais e vedações / Physical interfaces among plumbing, cast in-situ reinforced concrete and mansory systems
The identification and resolution of interfaces is a requirement that must be met for additional methods for evaluating design for Hydraulic and Sanitary Building Services (plumbing systems). The reason is that these building systems, in general, may have a higher incidence of problems of compatibility with others, because they all relate to. In this context

35. Estudo de materiais, estruturas de dispositivos e fenômenos de transporte em sistemas fotovoltaicos híbridos orgânico-inorgânico / Study of materials, device structures and transport phenomena in hybrid photovoltaic systems
Recently a fast development in organic and hybrid photovoltaic field has been observed. Such devices are fabricated by organic semiconductors within components of a heterojunction, in which bulk heterojunctions obtained via interpenetrating networks at the sub-20-nm length scale. It permits the effective collection of photogenerated charge carriers even with

36. Análise do comportamento de blocos sobre quatro estacas com cálice embutido / Analysis of the behavior of four-pile caps with embedded socket
A racionalização e a industrialização da construção civil têm promovido o sistema construtivo baseado em elementos de concretos pré-moldados. O comportamento das ligações entre os elementos pré-moldados constitui uma das principais preocupações dos projetistas, sendo as ligações entre a superestrutura e as fundações determinantes na estabili
