Calculating Vacancy Rate

Problem:Each time a price is displayed on osCommerce the tax rate for that product is queried. Even if the user has set to not display taxes with price the tax rate is queried.Solution:Query for each rate one time as it is needed and then store it in session cache.What this contribution does:This...

This is the update to the Percent module I put out "Shipping as a percentage of product price v1.0 ". This one allows a shipping amount to be applied to each individual product.As with the other module, I use the weight field to store the shipping amount, so if you use the weight field, you may...

This module calculates a surplus tax based on a table. The module is based on Zones.php and other contributions.Zones can be defined based on a country list. In case total amount is over the greatest tabled interval, then a percentage (if defined) is calculated.The admin configuration is in...

This script explains how to check that a given function does not run slower than a given pystone rate. It first calculates the pystone ratio on your box. This decoraone ratiot to use in production code, and would rather fit in functional or unit tests. This make performance tests portable to any...

This script contains a function to calculate the percent of requests that were "refused" by Apache server due to the clients ability to read the file from their cache instead. This function can be useful in performance analysis. The percentage of requests for cached files versus non-cached files...

EUDMODEL(DVH), where DVH is a 2 column matrix corresponding to the cumulative, not differential, dose volume histogram. The 1st column corresponds to increasing absolute dose or percentage dose values, and the 2nd column to the corresponding absolute or relative volume value. The matrix must have...
