Fresnel Diffraction Explorer 1.4
Fresnel Diffraction Explorer - Calculate numerically a Fresnel diffraction pattern more>>
Fresnel Diffraction Explorer is based on an efficient algorithm to calculate numerically a Fresnel diffraction pattern using any two-dimensional aperture.
It is a simple exercise to show that Fraunhofer diffraction by an aperture is mathematically equivalent to the Fourier transform of the aperture shape. Because the integrals describing Fresnel diffraction are so intractable, however, Fresnel diffraction patterns have few analytical solutions, even in one dimension. ... A calculation in two dimensions is even more problematic.
Enhancements:
Universal Application release for Intel- and PowerPC-based Macs running OS X. Clusters of any combination of Intel or PowerPC Macs can be used in a Fresnel diffraction calculation.
Other updates:
- OS X-compliant icons, dialog boxes, including sheets and antialiased text.
- Endian conversion for file and disk storage as well as sending data over the network.
- Adaptations to bundle formats and Xcode.
- When using multiple wavelengths, FDE can export to QuickTime in addition to PICS.
- Establishment of a data fork only file format.

CrystalDiffract 5.1.8 has come as an intuitive and effective program which helps effectively with x-ray and neutron powder diffraction patterns from crystals. CrystalDiffract can simulate and visualize diffraction patterns from any CrystalMaker binary file. You can manipulate patterns in real time, with extensive control over all aspects of the diffraction experiment - plus the ability to edit site occupancies and lattice parameters.
CrystalDiffract lets you display multiple diffraction patterns (simulated and real) in the same window. You can also simulate multi-phase mixtures (with variable phase proportions), plus energy-dispersive and time-of-flight diffraction.

Flipper 1.0
Flipper - Classic arcade game more>>
Your goal is to make all the rectangles in a grid the same, either the same pattern in black and white, or the same color on color machines
You change colors or patterns by clicking in the rectangle. Sound easy? Well, its a little more challenging than that. First, Flipper just wont leave things alone. At some random time Flipper will flip boxes from the current color to the next color, messing up all your planning. Second, it gets tougher as you go.
There will be more spaces in the grid, and more colors or patterns in the sequence (up to 30 colors). Third, the time that Flipper waits before changing colors also gets shorter as levels increase. And fourth, you only have 300 seconds (5 minutes) to complete each level.

LabScanner r9d is familiar among lots of users as a helpful data mining expert system for clinical laboratories which identifies, displays and prints temporal patterns in text files of test data exported from clinical laboratory information systems. It supports creation and management of pattern-detection rules by users, displays found patterns in interactive graphs, and allows printing of graphical reports and archiving of interesting patterns.
The program is targeted to therapeutic drug monitoring analyses but can be used with any test that gives a quantitative result. Versions for Macintosh and Windows, documentation, release notes and sample rules and data files are available from the Web site.
