Project: Wind Power Eliminator
Group: Thien Pham, Matheus Sousa
The Wind Power Eliminator is a complete stand-alone wind energy system, capable of emulating real-time behavior of wind generator. The Arduino based controller is implemented using MATLAB and Simulink software.
Section through the Mandelbrot-Julia set, defined as the points (z,c) in C^2 where z_{n+1}=z_n^2+c does not diverge for z_0=z. This section corresponds to z_0 = a real number, plotted from above to show that the "equator" z_0=0 is the Mandelbrot set. The color denotes the magnitude of the smallest iterate.

While dating, the focus is on what the boyfriend wants. After marriage, it's about what the wife wants.
MATLAB source code:
h = bar([75 46; 41 51]);
set(h(1),'FaceColor','b')
set(h(2),'FaceColor',[1,0.4,0.6])

Zooms of the Mandelbrot set around a point projected so that the distance to the point forms a logarithmic scale. Details on the left edge are ~10^15 times smaller than on the right edge.
The rightmost black blob in the pictures is the main "continent" of the set. Satelite sets of different sizes can be seen linked by fractal chains of varying complexity.
The colors are set using the distance estimator method.
The probability of having achieved human-level AI before a certain date implied by the answers to the Winter Intelligence conference survey. Respondents gave not only their estimates for when it was 50% chance of human-level AI but also 10% and 90%. Fitting a skew Gaussian probability distribution to each answer, the resulting average probability density gives an estimate of the collective belief.
The probability density in the past is due to tails of the component distributions being forced to extend before the present by certain answers.
The Lyapounov exponent measures how rapidly orbits diverge from each other. Here I calculated it approximatively for the Mandelbrot set.
Points inside the set converge to various cycles and hence have negative exponents. The shining centers of the components are the points that are right on a cycle. Points outside diverge to infinity, and have positive exponents. The unseen but intricate border includes both chaotic and periodic points.

The different species of the Cephalopoda, displayed with my Voronoi treemap. It tends to exaggerate the area of isolated small branches, which is not entirely wrong. The red polygon on the top is Spirula spirula, the only member of the family Spirulidae.
Topography maps of Titan based on the data in Lorenz et al. "A global topographic map of Titan" Icarus 225 (2013) 367–377.
The maps are based on small strips of Cassini radar observations that have been interpolated with splines; the real topography is of course more fractal. The elevations are fairly flat, with higher regions at the sub- and anti-saturnian points.
Resembling a woven blanket, this image is the MATLAB-generated visualization of 16,384 different experiments (each represented by a row) with 84 separate parameters (each represented by a column).

The Mammals, displayed using a further development of my Voronoi treemap code (now with nicer borders and more robust calculations). Each polygon represents a mammalian species or group of species, distributed inside larger groupings.

Las obra facilitara el uso de una poderosa herramienta, para operar y graficar funciones de variable real, y calcular la inversa y la compuesta de funciones, tales como las polinominales, exponenciales, logarítmica, trigonométricas y funciones por tramos.
La utilidad del Matlab radica en la gran rapidez para hacer cualquiera de los cálculos anteriores, y gráficas simultáneas que permiten una ágil visualización de los cambios que sufre una función ante una transformación. Es posible ver de inmediato el efecto de desplazamiento, alargamiento y reflexión.
El lector encontrará una descripción, paso a paso, del uso de las diferentes instrucciones en Matlab para calcular cualquiera de las operaciones básicas de funciones, algunas operaciones especiales, como la composición y la inversa, así como también una gran variedad de gráficos que mejoran los conocimientos respecto al dominio, al rango, la paridad y la periodicidad de una función.

En el texto MATLAB: aplicaciones a las matemáticas básicas, se abordarán una serie de problemas matemáticos utilizando el software MATLAB; así el estudiante mismo podrá estimar las bondades de esta poderosa herramienta y confrontarla con los métodos anuales.
El objetivo de este texto no es el de enseñar a programar en MATLAB, que es su aplicación fundamental, sino de mostrar sus alcances en problemas propios de las matemáticas básicas; para ello se ha seleccionado una serie de ejercicios de diferentes áreas de las matemáticas como el álgebra, la estadística y el cálculo.
Con la anterior consideración, el texto se presenta como un inicio al trabajo con MATLAB para ser empleado en cursos de apoyo e inducción; a su vez es una gran ayuda para que el estudiante cualifique su formación matemática básica y contribuir, de paso, a disminuir los niveles de pérdida y deserción de asignaturas
Here I color the Mandelbrot set based on the orbit of the points: each step adds red if it has negative real part, green if it has positive imaginary part and blue if it is outside the circle |z|=2/3. Each iteration contributes exponentially less, resulting in a color mixture.
It nicely fills in the "aura" close to the set.

Section through the Mandelbrot-Julia set, defined as the points (z,c) in C^2 where z_{n+1}=z_n^2+c does not diverge for z_0=z. This section corresponds to real c. The color denotes the magnitude of the smallest iterate.
Note the soft flat face, corresponding to the Julia set c=0.25 which suffers an implosion when c is increased, turning into rays of Fatou dust.
