In order to try these programs, and to understand them better, I translated each one to Java to run in a web browser applet. The picture above shows an orbit that is attracted to the orbit of an attracting periodic point of period 2. Below you see one which is attracted to the orbit of an attracting periodic point of period 3.

Of course it is american journal of infection control harder to find repelling periodic orbits. With some luck and a great deal of patience, some of the REU participants did manage to find some больше информации periodic points by this graphical method.

Click and ссылка на страницу the mouse to zoom in. Clicking the right mouse button zooms out. Clicking with the middle button opens a window with a picture of the filled Julia set associated to the c-value under the pointer. Click and drag to zoom in on the filled Julia set, or use the right button to zoom out. Clicking the middle mouse button toggles between a picture of the filled Julia set and a picture of the Julia set, i.

An estimate of the box dimension of the Julia set is displayed when the Julia set is visible. The Mandelbrot set is the set of values of c such that вот ссылка orbit of 0 does not escape to infinity. It is colored black in these pictures. For values of c that are not in the Mandelbrot set the orbit of 0 does escape to infinity.

We know that the orbit of 0 escapes to infinity if and only if some iterate has absolute value greater than 2. In our pictures of the filled Julia set the color of a pixel is black if the orbit of the corresponding z value does not escape from the circle american journal of infection control radius 2 after 256 iterates.

Otherwise the color represents the number of iterates before it does escape from the circle of radius 2 (and therefore escapes to infinity. We studied the theorem american journal of infection control the Julia set Jc is connected if c lies american journal of infection control the Mandelbrot set, and totally disconnected otherwise. As c moves from 0 to a point outside the Mandelbrot set the Julia set changes shape, breaking up into "fractal dust" as c crosses the boundary of the Mandelbrot set.

To run the program start a Python interpreter, import dust. The Autonomic Nervous System. Geneva: World Health Organization, 1999.

Basic Concepts Clinicians and basic investigators are increasingly aware of the remarkable upsurge of interest in nonlinear dynamics, the branch of the sciences widely referred to as "chaos theory. Therefore, the present discussion american journal of infection control an introduction to some key aspects of american journal of infection control dynamics, with a particular emphasis on heart rate control. A major challenge продолжение здесь in making these concepts accessible, not only to basic and clinical investigators, but to medical and graduate students at a formative stage american journal of infection control their training.

To appreciate the general clinical relevance of dynamics to the heartbeat, consider the following common problem. What is the best way to compare a sequence of measurements obtained from two subjects, or from one individual or experimental procedure under different conditions. Conventionally, clinicians and investigators rely primarily on a comparison of means using appropriate statistical tests. However, the limitations of such traditional analyses become apparent when evaluating the data in Fig.

Recording the instantaneous signal from any system over a continuous observation period generates a time series. What is noteworthy in this example is that these two time series have nearly identical means and variances, suggesting no clinically relevant differences. Yet, visual inspection indicates that the two sequences of data display a markedly different organization.

Time series analysis is concerned with quantifying the order of data points; nonlinear dynamics provides a deeper understanding of the mechanisms of patterns and differences such as those in Fig.
