1. Universal Approximators: New Approach for the Curve Fit of the COVID-19 Infected Population
ABSTRACT Fuzzy systems that include Takagi-Sugeno inference method with linear outputs, are widely known to have the ability to uniformly approximate any polynomial with high precision and, as a consequence, any continuous function, by applying the approximation theorem of Weierstrass. There is one more advantage for these methods which is to obtain an expli

2. El Sistema Informático de la Reforma GES en Chile: una etnografía de dispositivos de gobierno sanitario
Resumo Nas últimas décadas, as tecnologias da informação foram incorporadas aos sistemas de saúde por meio da criação de "redes assistenciais", que devem integrar diferentes níveis, instituições e agentes. No Chile, o regime de "garantias explícitas em saúde" (GES) liga-se a essas reformas modernizadoras do Estado, cujo objetivo é melhorar a efi

3. On the Use of an Interpolation Approach for the Choice of Gaussian Polarization Functions
In this work, we tested a linear interpolation approach in order to select polarization functions (exponents) to be used with Gaussian basis sets. The Gaussian primitive functions were generated here for Ga to Kr and also for Sc to Cu. The general contraction method was used for the construction of contracted Gaussian basis sets of 6Z and 7Z quality. Polariz

4. Methodology for The Development of an Ontology Network on The Brazilian National System for the Evaluation of higher Education (OntoSINAES)
ABSTRACT Ontologies occupy a central position in any conceptual model of the Semantic Web, aiming fundamentally to add explicit semantics to the contents available in the Web. In the domain of Brazilian higher education, especially with regard to the National System for the Evaluation of Higher Education (SINAES), still lacks a reference ontology that can pr

5. Omniscience and Semantic Information
ABSTRACT First, I consider a few motivations to idealize epistemic logics1 in such a degree that brings up the problem of logical omniscience [LOP]. I argue that the main motivation to hold omniscience is of a philosophical-scientific2 background (Stalnaker 1991), in the sense philosophers have a not so peculiar way of investigating underlying mechanisms, i.

6. Verificação da solução das equações de Saint-Venant com base no método difusivo de lax para propagação de vazões em canais naturais
ABSTRACT Hydrodynamic models, based on the Saint-Venant equations, represent the transient flow in water systems, and simulate flow routing over time and space. Several numerical solutions have been applied to these expressions, but often differences are found in results among distinct procedures, considering that all numerical approaches have limitations. N

7. MODELING AND ANALYSIS OF UNSTEADY FLOW BEHAVIOR IN DEEPWATER CONTROLLED MUD-CAP DRILLING
Abstract A new mathematical model was developed in this study to simulate the unsteady flow in controlled mud-cap drilling systems. The model can predict the time-dependent flow inside the drill string and annulus after a circulation break. This model consists of the continuity and momentum equations solved using the explicit Euler method. The model consider

8. A Decorporealized Theory? Considerations About Luhmann's Conception of the Body
Abstract The aim of this paper is to analyze the concept of body developed by Luhmann's systems theory. Privileged places where one can look for the body will be the interpenetration between human beings and the concept of socialization. Another fundamental problem is the relationship between semantics and body, although the most explicit presence of the bod

9. 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

10. Systems architecture, procedural knowledge and learning by using: implications on systems integration capabilities
The objective of this article is to assess the implications of systems architecture on the establishment of organizational learning cycles, and its influence on possible forms of process integration. Dynamics of innovation of complex systems do not follow the pattern of mass-production industries. In complex systems industries there is no dominant design and

11. Heat transfer to immiscible liquid mixtures in a spiral plate heat exchanger
This work presents new predictive correlations for heat transfer to immiscible liquid-liquid mixtures in a spiral plate heat exchanger. Liquid-liquid heat transfer studies were carried out in spiral plate heat exchangers for the water-octane, water-kerosene, and water-dodecane systems. For each composition of the mixture, the mass flow rate of the cold fluid

12. Numerical analysis of phase decomposition in A-B binary alloys using Cahn-Hilliard equations
The analysis of phase decomposition was carried out using the nonlinear and linear Cahn-Hilliard equations in a hypothetical A-B alloy system with a miscibility gap. These equations were solved by the explicit finite difference method assuming a regular solution model. The supersaturated solid solution and decomposed phases were considered to have an fcc str
