Moreover, our approach allows us to estimate the Hausdorff dimension of attractors of nonautonomous equations in terms of physical parameters. 漏 2000 John Wiley & Sons, Inc.V.InstituteV.InstituteChepyzhovInstit
Linear equations are important in physics and engineering. Some physical processes show a direct linear relationship, and even non linear relationships can often be approximated by systems of linear equations. When possible, we like to estimate with them because they are easy to manipulate and calcul...

In the table above we obtain an estimate for a numerical constant that seems to simulate natural growth processes, and that can be used to produce results that might otherwise requires an infinite number of infinitesimally small steps if they had to be computed as we have been doing. Here is...
As n increases, the interval on which the remainder gets close to zero increases to the right and left. • In the limit as n→∞, the interval on which the remainder approaches zero becomes the whole real line.Maple Solution The estimate for R^n • Write R...
To run this example, you must have licenses for Simscape and Symbolic Math Toolbox. DC Motor Model A DC motor is a device for converting electrical energy into mechanical energy and vice versa. A schematic of a DC motor is shown below (left figure). Blocks that simulate DC motors are ...

The speed regulator monitors the speed reference and speed estimate to determine a speed error and, from this, generates the commanded duty cycle needed to keep the motor running at the desired speed. The speed regulator is a conventional proportional plus integral type algorithm. ...
In math, time can be defined as an ongoing and continuous sequence of events that occur in succession, from past through the present, and to the future. Time is used to quantify, measure, or compare the duration of events or the intervals between them, and even, sequence events.Times of...
