1. Reduced Order Modeling of Composite Laminates Through Solid-Shell Coupling
ABSTRACT: Composite laminates display a complex mechanical behavior due to their microstructure, with a through-thickness variation of the displacement and stress fields that depends on the fiber orientation in each layer. Aiming to develop reduced-order numerical models mimicking the real response of composite structures, we investigated the capability and

2. Lateral decubitus position vs. lithotomy position: which is the best way to minimize patient’s pain perception during transrectal prostate biopsy?
ABSTRACT Introduction Considering the distinctive nature in terms of psychological stress and anal tone of position which is generally selected between lithotomy and left lateral decubitus (LLD), we postulated its effect on pain perception during biopsy, and investigated their association. Materials and Methods A prospective study for comparison of two b

3. Three-Dimensional Finite Element Analysis of Compressive Behavior of Circular Steel Tube-Confined Concrete Stub Columns by New Confinement Relationships
Abstract This paper presents a nonlinear analysis of axially loaded steel tube-confined concrete (STCC) stub columns with new confinement relationships. For this aim, a 3-D finite element model of STCC columns using ABAQUS program is developed and validated against the experimental data. Proper material constitutive models are proposed and the confinement pa

4. Aplicação de redes neurais artificiais no processo de ajuste de histórico / Application of artificial neural networks in the history matching process
The history matching process is one of the most important stages involving studies of reservoirs, because with the adjusted reservoir model, the production forecasts can be done with higher reliability and different production strategies can be evaluated to obtain greater final recovery associated with less costs. However, this process have several problems

5. Rastreamento em vídeo das características da pupila / Video tracking of pupil features
The study of the pupil s movements has signicant clinical interest because it acts as an objective indicator of retinal sensitivity to light and, consequently, of the optic nerve. Its permanent oscillation is the result of balance between opposing ows of the sympathetic and parasympathetic nervous system. The pupil s state of an individual allows the diagnos

7. HISTORY MATCHING IN RESERVOIR SIMULATION MODELS BY GENETIC ALGORITHMS AND MULTIPLE-POINT GEOSTATISTICS / AJUSTE DE HISTÓRICO EM MODELOS DE SIMULAÇÃO DE RESERVATÓRIOS POR ALGORITMOS GENÉTICOS E GEOESTATÍSTICA DE MÚLTIPLOS PONTOS
Na área de Exploração e Produção (EeP) de petróleo, o estudo minucioso das características de um reservatório é imperativo para a criação de modelos de simulação que representem adequadamente as suas propriedades petrofísicas. A disponibilidade de um modelo adequado é fundamental para a obtenção de previsões acertadas acerca da produção d

8. Petroleum reservoir uncertainty mitigation through the integration with production history matching
This paper presents a new methodology to deal with uncertainty mitigation using observed data, integrating the uncertainty analysis and the history matching processes. The proposed method is robust and easy to use, offering an alternative way to traditional history matching methodologies. The main characteristic of the methodology is the use of observed data

9. Graphical models and point pattern matching
This paper describes a novel solution to the rigid point pattern matching problem in Euclidean spaces of any dimension. Although we assume rigid motion, jitter is allowed. We present a noniterative, polynomial time algorithm that is guaranteed to find an optimal solution for the noiseless case. First, we model point pattern matching as a weighted graph match

10. A compact model of MOSFET mismatch for circuit design
This paper presents a compact model for MOS transistor mismatch. The mismatch model uses the carrier number fluctuation theory to account for the effects of local doping fluctuations along with an accurate and compact dc MOSFET model. The resulting matching model is valid for any operation condition, from weak to strong inversion, from the linear to the satu

11. 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

12. Impactos da restrição ao crédito rural nos estabelecimentos agropecuários brasileiros / The impact of rural credit restriction to brazilian farmers
The rural credit was implemented in the late 1960s and thenceforth it became one of the major agricultural policies in Brazil. From its inception, the program relied on government subsidies obtained through interest rates, offsetting in part the resources shift from the agricultural sector promoted by the import substitution process. The credit policy direct
