ACCORD is a C library for composition of SEM or scanning helium-ion microscope images with correction of drift. It is able to compose (average) large sets of extremely noisy images that were acquired by scanning charged-particle microscopes at the highest possible speeds (lowest pixel-dwell times). If the images are composed using traditional techniques, they usually become extensively blurry. The technique that is implemented in this software corrects these derogations by pre-shifting the composed frames.
The Artificial SEM Image Generator (artimagen) library generates artificial scanning electron microscope (SEM) and helium-ion microscope images of various samples, including gold-on-carbon resolution samples and some semiconductor structures. Numerous effects that appear in real SEMs are simulated (noise, drift-distortion, edge-effect, etc.), which enables assessment of imaging, metrology, and other techniques that work with SEM micrographs. Unlike the real SEM images, the artificial images exhibit defined types and amounts of these effects, which is their key advantage.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
BitTorrent is a tool for copying files from one machine to another. FTP punishes sites for being popular. Since all uploading is done from one place, a popular site needs big iron and big bandwidth. With BitTorrent, clients automatically mirror files they download, making the publisher's burden almost nothing.
The Bitcollider utility allows users to uniquely identify and submit files to Bitzi's community metadatabase project. The Bitcollider can be used to identify any local file and has support for extracting metadata from MP3, WAV, Vorbis, JPEG, PNG, GIF, AVI, MPEG-1, MPEG-2, and QuickTime files. Users can quickly look up all the known information about the given file in Bitzi's metadatabase.
Booruatsukaigaumai is a one-key desk game using OpenGL 3D scene rendering. Your task is to guide a number of red balls through 6 different levels full of blocks, holes, and gates. You have to make the balls go through as many gates as possible, which earns you the score points. However, you only have one key to control the desk tilt, which makes balls roll to the right (when the key is pressed) or to the left (when the key is released). Any other movement of the balls is controlled only by gravity and interaction with blocks, holes, and other balls. Even if the principle seems to be very simple, the game can be quite challenging.
The National Space Science Data Center's (NSSDC) Common Data Format (CDF) is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion. It consists of a scientific data management package (known as the "CDF Library") that allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.
