Measuring Angles With A Protractor

This package includes a configurable Simulink model for three different types of DC-DC converters (Buck, Boost and Buck-Boost converters) with a PWM PI controller. The example provided shows a case to boost voltage from 5 volts to 25 volts. It can be used to learn DC-DC converters and their...

n the bottom of a Stefan tube there is a quiescent liquid with a mixture of acetone (component 1) and methanol (component 2). Vapor that evaporates from this pool of liquid diffuses to the top of the tube. Air (component 3) keeps the mole fractions of components 1 and 2 equal to zero. This...

We would like to rise water temperature with a heater. Oulet temperature must be equal to the set point temperature (80dlT-C). Proportional (P), Proportional-Integral (PI) and Proportional-Integral-Derivative (PID) control are used and the respective results are compared. Inlet water temperature...

Control a 53132A counter remotely using standard Matlab without the instrument module by treating the GPIB USB interface as a com port. There are lots of little tricks to get this to work. This module also uses a small program SystemError, which is also uploaded to this site, to help debug this...

VIDEOFIG(NUM_FRAMES, @REDRAW_FUNC) creates a figure with a horizontal scrollbar and shortcuts to scroll automatically. The scroll range is 1 to NUM_FRAMES. The function REDRAW_FUNC(F) is called to redraw at scroll position F (for example, REDRAW_FUNC can show the frame F of a video).This can be...

This function draws text on a figure with a 1-pixel-thick border, which may be useful when simple text would be hard to read due to low contrast.TEXTBORDER(X, Y, STRING)Creates text on the current figure with a one-pixel border around it. The default colors are white text on a black border, which...
