Diffraction Pattern

This script is an implementation of the prototype pattern. In the prototype pattern you create a new instance cloning from other. Platforms: Windows, Mac, *nix, Python, BSD Solaris

Memento design pattern in python script allows you to cache instances based on what arguments are passed to them. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This is a Python implementation of the observer pattern. It defines a one-to many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script separates pattern implementation from your code so that you can reuse the implementation elsewhere. It is an example that shows a reusable implementation of the Observer pattern. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This applet shows the Fresnel and Fraunhofer diffraction patterns. The applet includes some default objects such as the slit, the rectangle and the circle, whose geometrical characteristics can be modified. Platforms: Mac

The Diffraction and Interference Model: Single and Double Slits shows diffraction and interference patterns from a single slit, double sources and double slits. The user can change the source wavelength, slit width, separation and distance between slit and screen. The Diffraction and... Platforms: Mac

This screensaver lets you observe a live ornamental pattern of metal in your display. The pattern shows a current time and he is never repeated. The moving lightes supplement this mysterious picture. The screensaver uses 3D graphics, but he requires only a version 1 of OpenGL. Dark design... Platforms: Windows

Fresnel Diffraction Explorer simulates Fresnel diffraction by any two-dimensional aperture using an algorithm published in the Nov/Dec 1996 issue of Computers In Physics. It contains an interactive user-interface and a self-demo to aid in use of the algorithms. Parallelized for use with Pooch on... Platforms: Mac

Graphic Styles Pack 3 has 900 pattern themed graphic styles, many mixed style designs from square pattern designs to circular pattern designs to weird surreal designsThe symbols download here are merely a small sampling of the graphic styles set - the demo contains 5 symbolsAccess the graphic... Platforms: Mac

In this game there will be a grid of blocks. Some of the blocks will be coloured for a few seconds for you to memorize the pattern, the colours will then disappear and you will need to put the colours into the grid to reproduce the original pattern of colours. As the game progresses the grid will... Platforms: Windows

Whether you are into knitting, cross stitch, quilting or woodworking, Pattern Minder is for you. It is the easy to use app to keep track of all your patterns. You can attach a scanned copy of the pattern, as well as a picture of the finished product. You can categorize your patterns in any way... Platforms: Mac

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. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This 15-line matlab program solves the nonlinear reactiondiffusion equation, called Kolmogorov-Petrovskii-Piskunov(KPP) equation to generate patterns (ribbons and rings).The numerical method is simple and program is easy tounderstand, and it can be extended to simulatedmore complex systems. The... Platforms: Matlab

A collection of m-files aimed at learning and teaching about the principles of diffraction gratings. Some of these show a cross section of the geometry of a diffraction grating, a common illustration in textbooks of optics, spectroscopy, and analytical chemistry.Sliders on the figures allow...

The Strategy Pattern is just one of many patterns defined by the "Gang of Four" that are commonly used in many other object-oriented programming languages.Now with Matlab 2008b we can define Interfaces and Abstract classes that can make use of many of these patterns. Not only is this good coding... Platforms: Matlab
