This paper presents the method to visualize a set of feasible loading points, called “feasible regionâ€, in the two-dimensional power flow solution space. The visualization can be done by tracing the boundary of feasible region. The boundary points are ... see more

In the paper, a mathematical model of an E-plane junction of three waveguides has been presented and justified. The coupling cavity ofthe waveguide transformer in question has an arbitrary triangular shape. The problem of scattering of waveguide modes is ... see more

The mathematical justification of an earlier full-wave model for a symmetrical junction of N rectangular waveguides coupled in E-plane is presented in the paper. The problem of scattering of waveguide modes is formulated in the form of a boundary value-pr... see more

The subject of the study is a set of theoretical and methodological aspects of development strategy formed for objects (country, region, branch, enterprise) on the basis of the life cycles theory under the external environment uncertainty. The methodology... see more

O artigo aborda a concentração geográfica da inovação e pondera sobre sua correlação com as desigualdades regionais, com ênfase na análise da Lei nº 11.196/2005, conhecida como Lei do Bem, que cria renúncia fiscal para empresas brasileiras investirem em P... see more

Este artigo descreve dois dos mais recentes esforços de integração sub-regional na América do Sul, a ALBA e a UNASUL, incluindo os fatores que contribuíram para o seu desenvolvimento. A análise aqui oferece atenção especial ao papel desempenhado pelo gove... see more

Critical thinking goes beyond memorization, promotes independent thinking and reasoned judgment. It is a crucial element in connecting ideas, solving problems, and creating knowledge. Schools are considered to be among the initial steps in developing crit... see more
