The calculation of variations initially it was a technique that was born in the field of physics and its great contributions have been taken advantage of by the engineering sciences in problems that involve finding a minimum ...

This article exposes the implementation of the H2 controller, which is rare in the literature because it is a more robust control and not only errors but also disturbances that can affect the dynamics of the control system ...

This paper deals with the problem of the optimal placement and sizing of distributed generators (DGs) in alternating current (AC) distribution networks by proposing a hybrid master–slave optimization procedure. In the ...

The optimal placement and sizing of distributed generators is a classical problem in power distribution networks that is usually solved using heuristic algorithms due to its high complexity. This paper proposes a different ...

The problem of the optimal placement and dimensioning of constant power sources (i.e., distributed generators) in electrical direct current (DC) distribution networks has been addressed in this research from the point of ...

Road infrastructure projects are essential for the economic growth and development of a country, because they provide great advantages in the mobility of people, as well as goods or consumer products, thus making it possible ...

In this work, we found that tomato and guava plants infected with Meloidogyne enterolobii showed different Fourier-transformed infrared spectral patterns compared to non-infected plants. Additionally, by using two-dimensional ...

This paper explores the problem of optimal calculation of electrical parameters in solar cells using three well-known operative points provided by manufacturers considering a single-diode model. These are open circuit, ...

Several existing reinforced concrete (RC) buildings fail to conform with current seismic codes, increasing its susceptibility to damage and collapse during earthquakes. A concern for building upgrading and rehabilitation ...

This paper analyzes the problem of optimally sizing a transmission shaft via the vortex search algorithm (VSA) optimizer. The objective function was to minimize the shaft weight through an adequate selection of the diameters ...
