Free neutron powder diffraction software for mac

Diffraction is an important physical effect inherent in all wave phenomena. Fraunhofer and Fresnel diffraction are two important classes of diffraction. Fraunhofer diffraction involves coherent plane waves incident upon an obstruction. Fresnel diffraction is the same, except that the waves are spherical, effectively originating from a point source.
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.

POWDER 110 is a kind of game formed in the genre of Rogue, Nethack, and Diablo. Emphasis is on tactical play - this isn't a twitch game like Quake or a high level strategy game like Warcraft.

Developed originaly for the Gameboy Advance, and since ported to many platforms, POWDER possesses a simple interface that doesn't detract from the depth of the gameplay. Full mouse support is present and the game can be played entirely with a stylus interface.

Requirements:
Mac OS X 10.0 or later.

Enhancements:
Version 1.4: Simplified menu, added icon (courtesy of Andrew Smith), disabled close and maximize buttons, added placeholder for units of weight.

Requirements: Mac OS X 10.3.9 or later.

X-ray Detector Software for processing single-crystal monochromatic diffraction data recorded by the rotation method.
XDS can process data images from CCD-, imaging-plate, and multiwire-detectors in a variety of formats. Detector specific Input file templates greatly simplify the use of XDS; they are provided as part of the documentation.
XDS runs under Unix or Linux on a single server or a grid of up to 99 machines of the same type managed by the MOSIX system; in addition, by using OpenMP, it can be executed in parallel on up to 32 processors at each node that share the same address space.
Enhancements:
- Bug fix for the ADSC Q315 detector when the image header exceeds 512 bytes.
