1. Analysis and Optimization of Ultra-Low-Power Rectifier with High Efficiency for Applications in Wireless Power Transmission and Energy Harvesting
Abstract The system capable of harvesting RF energy from the environment through an antenna and converting it into direct current energy to deliver to a load is known as rectenna. The rectifier circuit is an important part of the rectenna and its modeling is arduous since it employs a non-linear device working at extremely low power levels. In addition, ther

2. Evaluation of a rat model of exercise-induced fatigue using treadmill running with progressively increasing load
Abstract: The mechanism behind exercise-induced fatigue is a significant topic in the field of sports physiology. Therefore, establishing and evaluating an acute exercise-induced fatigue animal model that explores the limits of the motor system may provide greater insight into these mechanisms. Heart rate is an important quantitative parameter that accuratel

3. Contribution to hierarchical modeling in tunnel design practice
Resumo Esse trabalho apresenta uma análise comparativa entre duas hierarquias de modelos comumente aplicadas no projeto estrutural de túneis: modelos de maciço contínuo e de anel sobre apoios. Primeiramente, as principais características de cada modelo e as interfaces entre ambos são discutidas. Baseado em tais avaliações um procedimento simples é p

4. Structural models for analysis of reinforced concrete frame buildings with masonry infills
Resumo Este trabalho tem como objetivo o estudo do comportamento de pórticos de edifícios de concreto armado preenchidos com alvenaria frente às ações horizontais, empregando-se dois modelos estruturais: i) modelo de diagonal equivalente (MDE) e ii) modelo com elementos finitos bidimensionais para estado plano de tensões (MEF). No primeiro modelo, a al

5. Modular modeling approach for FDM printed structures and piezo disks for metamaterial design
Abstract Research in metamaterials has recently gained interest in the field of noise and vibration control. The ability of creating band gap zones with minimum added mass is the main feature behind its success. In addition, the use of 3D printed parts, particularly the Fused Deposition Modeling (FDM), offers a practical solution for manufacturing parts with

7. Numerical fundamentals and interactive computer graphics system for the nonlinear analysis of planar frames
Abstract Recent scientific and computational advances have facilitated the analysis of slender structural systems subject to instability. With the employment of more sophisticated numerical tools and algorithms, it is possible to accurately determine the critical points (limit and bifurcation loads) as well as the post-critical behavior of the structural sys

9. Influence of ceramic material, thickness of restoration and cement layer on stress distribution of occlusal veneers
Abstract The aim of this study was to evaluate stress distribution in an occlusal veneer according to the restorative material, restoration thickness, and cement layer thickness. A tridimensional model of a human maxillary first molar with an occlusal veneer preparation was constructed using a modeling software of finite element analysis. The model was repli

10. Numerical simulation of bolted connections
Abstract This article presents the modeling of a complete bolted connection based on a model with one bolt connecting two or three plates. Initially, the behavior of this model with one bolt is analyzed by comparing it with existing bibliography for 3 different types of applied load: tension, shear and a combination of these two. This model includes all nece

11. Aspects of Finite Element Modeling of Punching Shear Behavior of Reinforced Concrete Flat Slabs
Abstract A series of nonlinear FE analyses was conducted in this paper to model the punching shear failure of RC flat slabs. The analyses were carried out in the software DIANA using three-dimensional continuum elements. These analyses involve the test of different modeling choices in order to evaluate their influences on punching shear failure modeling. The

12. Numerical analysis of truss systems with stiffened flattened end-bars
Abstract Circular hollow sections are usually used in long-span roof truss systems. One of the typology for connecting elements in such structures involves the flattening of bar ends. This article presents the numerical analysis of a plane truss composed of circular hollow sections, in which diagonal bars have flattened ends. In this sense, a new flattening
