1. Partículas de Final de Sentença (PFS): uma análise cartográfica por fases sobre o sistema da língua Tenetehára
Resumo O objetivo deste artigo é analisar a distribuição das Partículas de Final de Sentença (PFS) em Tenetehára, as quais compõem um conjunto de itens funcionais que ocorrem em uma posição sintática rígida em posição sentencial final. A ordem das PFS nesta língua pode ser formalmente capturada se for considerada uma única estrutura de base, a

2. Effects of soil-structure interaction in seismic analysis of buildings with multiple pressurized tuned liquid column dampers
Abstract In this paper soil-structure interaction (SSI) effects are investigated while an array of Pressurized Tuned Liquid Column Dampers (PTLCD) is employed for seismic vibration control of buildings. This device represents the most general case of a passive damper, with different reduction options to other control devices obtained by simplifying the invol

3. Cardiorespiratory and metabolic determinants during moderate and high resistance exercise intensities until exhaustion using dynamic leg press: comparison with critical load
The objective of this study was to assess cardiovascular, respiratory, and metabolic responses during a commonly used dynamic leg press resistance exercise until exhaustion (TEx) at different intensities and compare with critical load (CL). This was a prospective, cross-sectional, controlled, and crossover study. Twelve healthy young men (23±2.5 years old)

4. Analysis of a tuned liquid column damper in non-linear structures subjected to seismic excitations
Abstract The behavior of the tuned liquid column damper (TLCD) is analyzed in the control of non-linear structures subjected to random seismic excitations. The structure is modeled as a system of one degree of freedom with incursion in the non-linear range. The Bouc-Wen hysteretic model is used to model the non-linear behavior of the structure. A stationary

5. Application of methodology for the adequacy of the electrical motor's power sizing: permanent and transient analysis
Abstract The suitability of the motive force contributes to the efficient use of electrical energy. On the other hand, the inadequate size of electric motors is directly connected to increased investment and running costs. This article presents the theory and mainly the application of a methodology for the adequacy of the motive power. The research was condu

6. The Equivalent Linearization Method with a Weighted Averaging for Analyzing of Nonlinear Vibrating Systems
Abstract In this paper, the Equivalent Linearization Method (ELM) with a weighted averaging, which is proposed by Anh (Anh, 2015), is applied to analyze some vibrating systems with nonlinearities. The strongly nonlinear Duffing oscillator with third, fifth, and seventh powers of the amplitude, the other strongly nonlinear oscillators and the cubic Duffing wi

7. The Control of Asymmetric Rolling Missiles Based on Improved Trajectory Linearization Control Method
ABSTRACT According to motion characteristic of an asymmetric rolling missile with damage fin, a three-channel controlled model is established. The controller which is used to realize non-linear tracking and decoupling control of the roll and angle motion is introduced based on an improved trajectory linearization control method. The improved method is compos

8. An Accurate Study on Capacitive Microphone with Circular Diaphragm Using a Higher Order Elasticity Theory
Abstract This study has been undertaken to investigate the mechanical behavior of the capacitive microphone with clamped circular diaphragm using modified couple stress theory in comparison to the classical one. Presence of the length scale parameter in modified couple stress theory provides the means to evaluate the size effect on the microphone mechanical

9. A Comparative Study of Four Feedback Linearization Schemes for Motion Planning of Fixed-Wing Unmanned Aerial Vehicles
ABSTRACT In this paper, different feedback linearization schemes are studied to address the motion planning problem of fixed-wing unmanned aerial vehicles. For a unmanned aerial vehicle model with second-order dynamics, several schemes are studied to make the vehicle (i) fly over and (ii) make a loitering around the objective position. For each scheme, compa

10. Finite element model based on refined plate theories for laminated glass units
AbstractLaminated glass units exhibit complex response as a result of different mechanical behavior and properties of glass and polymer foil. We aim to develop a finite element model for elastic laminated glass plates based on the refined plate theory by Mau. For a geometrically nonlinear description of the behavior of units, each layer behaves according to

11. ON AUTOMATIC DIFFERENTIATION AND ALGORITHMIC LINEARIZATION
We review the methods and applications of automatic differentiation, a research and development activity, which has evolved in various computational fields since the mid 1950's. Starting from very simple basic principles that are familiar from school, one arrives at various theoretical and practical challenges. The resulting activity encompasses mathematical

12. Study of Conservation on Implicit Techniques for Unstructured Finite Volume Navier-Stokes Solvers
ABSTRACT: The work is a study of conservation on linearization techniques of time-marching schemes for the unstructured finite volume Reynolds-averaged Navier-Stokes formulation. The solver used in this work calculates the numerical flux applying an upwind discretization based on the flux vector splitting scheme. This numerical treatment results in a very la
