Using Neat Receipts

This script implements set operations using sorted lists as the underlying data structure. Advantages: - Space savings -- lists are much more compact than a dictionary based implementation. - Flexibility -- elements do not need to be hashable, only __cmp__ is required. - Fast operations...

The script illustrates the composite design pattern by using hierarchical dictionaries. It can be used to process hierarchical, tree-based data structures using Python dictionaries.

This script can be conveniently used to obfuscate a string of data using simple xor without using any key.

In this document I show how to verify the functionality of your DSP code via processor in-the-loop (PIL) co-simulation using Simulink?s UDP (user datagram protocol) blocks. These blocks are a new addition to the R2006b release of Simulink. This example is an extension of a previous example which...

The control of both bottom and distillate compositions is achieved by using conventional two point feedback control (WoodandBerry1) and non-interacting control (WoodandBerry2). Because of coupling, conventional control has a poorer performance when compared to the non interacting control system....

In the programs, we perform flash calculations of a mixture of hydrocarbons (ethane, propane, n-butane and n-pentane) using the Rachford-Rice equation. The phi-phi method, based on the SRK equation of state, is used to compute the equilibrium constants. We also find the True Vapor Pressure. All...
