1. A Note on the Well-Posedness of Control Complex Ginzburg-Landau Equations in Zhidkov Spaces
ABSTRACT In this note, we consider the Complex Ginzburg-Landau equations with a bilinear control term in the real line. We prove well-posedness results concerned with the initial value problem for these equations in Zhidkov spaces using splitting methods.

3. OPTIMIZATION OF DYNAMIC VIBRATION ABSORBERS BASED ON EQUAL-PEAK THEORY
Abstract The present paper proposes a new procedure to determine the optimal parameters of a dynamic vibration absorber (DVA), considering both damped and undamped primary system. The DVA design is formulated as an optimization problem in which the objective function is constructed based on Den Hartog's equal-peak method. The DVA parameters are selected to m

4. Mejora en la calidad de imágenes ultrasónicas aplicando métodos de composición espacial y empleando sistemas de Phased Array
ABSTRACT The Phased Array Ultrasonic Technique (PAUT) has become a widely used imaging tool for the Nondestructive Testing in the industrial field. The PAUT allows making deflections and focusing the ultrasound beam at different depths within the material, through an electronic control of each one of the N elements that make up the array transducer. Thus, se

7. Quality Evaluation of Chromatic Interpolation Algorithms for Image Acquisition System
ABSTRACT The main goal of the Libertad 2 mission is to take images of the Earth’s surface in the visible spectrum with a multispectral sensor and send them as a Bayer array. To carry out the reconstruction in land of these images and to view them in a RGB color model, it is necessary to use a color interpolation algorithm to determine the values of the dif

8. A bilinear elastic constitutive model applied for midpalatal suture behavior during rapid maxillary expansion
Introduction : This study aims to evaluate the influence of the biomechanical behavior of the midpalatal suture (MPS) during the rapid maxillary expansion (RME) when modeled by the Finite Element Method. Methods Four simulation alternatives are discussed and, for each analysis, the suture is considered as a functional unit with a different mechanical behavi

9. Numerical analysis of highly deformable elastoplastic beams
AbstractThe objective of the present study is to develop a numerical formulation to predict the behavior of highly deformable elastoplastic thin beams. Following the Euler-Bernoulli bending, the axial and shear effects are neglected, and the nonlinear second-order differential equation regarding the angle of rotation is defined based on the specific moment-c

10. In silico Antibacterial Activity Modeling Based on the TOMOCOMD-CARDD Approach
In the recent times, the race to cope with the increasing multidrug resistance of pathogenic bacteria has lost much of its momentum and health professionals are grasping for solutions to deal with the unprecedented resistance levels. As a result, there is an urgent need for a concerted effort towards the development of new antimicrobial drugs to stay ahead i

11. 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

12. Composed Mathematical-Informational modeling of column-base connections
Depending on the type of structural analysis required, any moment-rotation curve representation can be used; these include linear, bilinear, multi-linear and nonlinear representations. The most accurate representation uses continuous nonlinear functions. In this study, two distinct approaches are proposed to account for the complex hysteretic behavior of col
