Volume Of A Sphere

This one line function adds up the ascii values of a string and returns the total as a checksum. Also included is a variation which returns the checksum mod 256 (so it can be used as a single byte).The same technique can be used to add up a list of numbers, or to return the average of a list...

This script contains a function to check on the occurence of a set of characters.

We compare computed temperature distributions using both pdepe and analytical solutions for different geometries (slab, cylinder and sphere). Solids are kept initially at uniform temperature. For t>0, the boundary surface is kept at constant temperature. Results show excellent agreement....

If you are listening to music on the earphone, Xmart Volume may help you turn down the music volume for a conversation. And then restore the music volume when the conversation finished. Perfect for 'lazy' music lover! Xmart Volume utilizes the built-in microphone of your Mac or iSight to perform...

This module uses a visitor's IP address to identify the geographical location (country) of the user. The module makes this determination and stores the result as an ISO 3166 2-character country code in the Drupal $user object, but otherwise has no effect on the operation of your site. The intent...
