1. Elaboração e análise sensorial de biscoito tipo cookie feito a partir da farinha do caroço de abacate
Resumo Uma boa alternativa que vem sendo desenvolvida e aplicada nos últimos anos é o aproveitamento de resíduos oriundos do processamento de frutas e hortaliças. Grande parte do que é descartado dessas matérias-primas, tais como cascas, sementes e talos, pode ser reaproveitada na produção de novos alimentos. Este trabalho teve como objetivo desenvol

3. Buckling Analysis of Laminated Anisotropic Kirchhoff’s Plates via The Boundary Element Method
Abstract A new fundamental solution for laminated anisotropic Kirchhoff’s plates with out-of-plane and in-plane compressive loads is derived here. The multicompressed solution for both isotropic and anisotropic cases is obtained via the Radon Transform. Some fundamental kernels of the integral equations are described in detail. BEM results of displacements

4. DBD Plasma: Explicit Model with Integral Approximate Solution to Wall Jet
ABSTRACT: This study aims to first introduce a formulation which is quite simple for obtaining dielectric-barrier discharge plasma spatial body force. This new model comprises a combination of an empirical model and a numerical one. Although there are still some limitations in the new model (restriction to specific geometry, maximum voltage amplitude of 30 k

5. Seismic Pressures in Offshore Areas: Numerical Results
Abstract The purpose of this study is to obtain numerical estimations of seismic pressures in offshore areas considering the effect of seabed configurations and soil materials. To this end, the Boundary Element Method is used to irradiate waves, so that force densities can be obtained for each boundary element. From this hypothesis, Huygens´ Principle is im

6. A New Displacement-based Approach to Calculate Stress Intensity Factors With the Boundary Element Method
Abstract The analysis of cracked brittle mechanical components considering linear elastic fracture mechanics is usually reduced to the evaluation of stress intensity factors (SIFs). The SIF calculation can be carried out experimentally, theoretically or numerically. Each methodology has its own advantages but the use of numerical methods has become very popu

7. The Local Formulation for the Modified Green's Function Method
AbstractThe Modified Global Green's Function Method (MGGFM) is an integral technique that is characterized by good accuracy in the evaluation of boundary fluxes. This method uses only projections of the Green's Function for the solution of the discrete problem and this is the origin of the term 'Modified' of its name. In this paper the local strategy for cal

8. Finite element modeling for buckling analysis of hybrid piezoelectric beam under electromechanical loads
A one-dimensional finite element model for buckling analysis of hybrid piezoelectric beams under electromechanical load is presented in this work. The coupled zigzag theory is used for making the model. The inplane displacement is approximated as a combination of a global third order variation across the thickness with an additional layer wise linear variati

9. Nonlinear wave transmission and pressure on the fixed truncated breakwater using NURBS numerical wave tank
Fully nonlinear wave interaction with a fixed breakwater is investigated in a numerical wave tank (NWT). The potential theory and high-order boundary element method are used to solve the boundary value problem. Time domain simulation by a mixed Eulerian-Lagrangian (MEL) formulation and high-order boundary integral method based on non uniform rational B-splin

10. Simulation of irregular waves over submerged obstacle on a NURBS potential numerical wave tank
In this paper, a fully non-linear three-dimensional Numerical Wave Tank (NWT) is developed for studying propagation and scattering of non-linear random sea wave over bottom submerged bars. The simulation of fully non-linear free-surface is based on Non-Uniform Rational B-Spline formulation (NURBS) as a novel approach and Mixed Eulerian-Lagrangian method (MEL

11. Far-field dynamic behavior of a half-space under an inertial strip foundation subjected to a time-harmonic force
Recent research works demonstrated that the interaction between the loads and the carrying structure's boundary which is related to the inertia of the load is an influential factor on the dynamic response of the structure. Although effects of the inertia in moving loads were considered in many works, very few papers can be found on the inertial effects of th

12. A non-standard optimal control problem arising in an economics application
A recent optimal control problem in the area of economics has mathematical properties that do not fall into the standard optimal control problem formulation. In our problem the state value at the final time the state, y(T) = z, is free and unknown, and additionally the Lagrangian integrand in the functional is a piecewise constant function of the unknown val
