Blackboard Trouble

• For a problem with the 22 site, or if you need get access to it, email the people who maintain the 22 site:  Charlie Sullivan and Katie Tippit.  
• If there seems to be trouble with the Blackboard system:
• Email Blackboard Support.
• Email Mark O'Neil.
• Email Dartmouth Help.
  
• If all else fails and it's really urgent (you need access to study materials and a test is coming up shortly, and you are sure that the system is down because you've checked with others in the class and they can't get on either), email or (probably better) call the machine room at 646-2075.
  

Lab Stuff

• Aglient tutorial on oscilloscopes .
• Manual for our 'scopes.
• Scope operation animation .  From Williamson Labs.
• Scope triggering MATLAB animation . Show why triggering is needed and why slope discrimination is needed for triggering.  The file scopani.m can be run by typing just scopeani at the matlab prompt (if the file is in a directory matlab can find ).

Cover images

• Solar-powered water pumping system at Alternative Energy Systems Co.
• A slick, effient, single-passenger electric vehicle, the Sparrow
• A bioreactor for producing monoclonal antibodies
• A micro-electro-mechanical jig to measure the electrical impedance of a single biological cell
• A prototye maglev train .

Units

• Dictionary of Units including conversion factors to SI units, from University of Exeter.

Animations

• Snubber circuit MATLAB animation .  Animation of the RC snubber circuit from lab.  The file snubani.m can be run by typing snubani(Rs) at the matlab prompt, where Rs is the snubber resistor value (if the file is in a directory matlab can find ).
• Scope operation animation .  From Williamson Labs.
• Scope triggering MATLAB animation . Show why triggering is needed and why slope discrimination is needed for triggering.  The file scopani.m can be run by typing just scopeani at the matlab prompt (if the file is in a directory matlab can find ).
• Mechanical and acoustical demos by Prof. Russell at Kettering University.

MATLAB Stuff

• MATLAB "help desk" on a local server.

M-Files

• nareul.m . Narrated "Euler's method" differential equation solver. Works like ode45, but with more explanations and with error checking. But it's not nearly as fast or as accurate as ode45.
• Second-order response demo, "secondrand".
• Old version of second-order response demo, that uses the same system every time.
• Addplot function to plot multiple plots on a single set of axes, sequentially using differnet colors and line styles.
• Scope Triggering MATLAB animation . Show why triggering is needed and why slope discrimination is needed for triggering.  The file scopani.m can be run by typing just scopeani at the matlab prompt (if the file is in the a directory matlab can find).
• Error2bar function to plot error bars with x and y error
• "big", a MATLAB utility to enlarge figure text
