A comparison between “rod counting” and “box counting” methods in linear fractal dimensions measurements
C. Acosta, F. Peñuñuri, O. Carvente, G. Rivadeneyra, I. Martín

Rev. int. métodos numér. cálc. diseño ing. (2022). Vol. 38, (3), 27

Abstract
In this work, the “rod counting” method is reviewed in comparison with the “box counting” method applied to linear measurements on irregular figures. Both methods are applied in measurements of fractal dimension of some knowing fractals. Results shows that the “rod counting” method is more accurate in linear measurements. Later the method is applied in a Mandelbrot fractal figure to measure its perimeter fractal dimension.

Fractal dimension measured over areas and perimeters using “Box Counting” technique applied over a Mandelbrot figure.
C. Acosta, F. Peñuñuri, O. Carvente

Rev. int. métodos numér. cálc. diseño ing. (2022). Vol. 38, (1), 11

Abstract
Measuring fractal dimension in general is made over edges of a figure, however this kind of calculations could be made over a 1D, 2D or even a 3D images. With the FracLac plugin of ImageJ application, it has been possible to measure both dimensions, over the area and over the edge of a Mandelbrot fractal, using the Box Counting technique.

Annual distribution of the Sun’s angular positions, study at 21 degrees of latitude
C. Acosta, O. Carvente-Muñoz, F. Peñuñuri-Anguiano, M. Zambrano-Arjona, G. Rivadeneyra-Gutiérrez

Rev. int. métodos numér. cálc. diseño ing. (2019). Vol. 35, (1), 5

Abstract
It is well know that the Sun position, measured over the heart surface is a function of the latitude and the hour of a particular day. Usually, the Sun follows a different path from one day to the next, and this is determined by the azimuth and zenith angles. The analytical calculations for determining the angular position at any time (solar hour) are an overwhelming task. We use the Mathematica® software to write a home code for determining at any time (in intervals of one minute) and latitude, the azimuth and zenith angles of the Sun for every day of the year. In order to show general results of interest, in this work we present the annual distribution of the angular positions and the length of the day (hours of light) for the 21 degrees of latitude. This information could be used for optimizing the orientation of solar panels and collectors and for the design of cheap houses where the walls can be exposed to the minimal solar incidence.
