Mathnetics is an API for creating advanced, interactive, Web-based mathematical applications. It defines various important mathematical objects that are inter-related and on which many numerical calculations can be done. It also features rendering of 3D objects onto an SVG canvas (to do so, it includes certain utilities such as browser sniffing, DOM node selection, and DOM readiness detection), which is quite robust. A few basic 3D objects are given (Line, Sphere, Cube), but the user can define any 3D object desired as per the specification.
GNotary is a set of Python scripts that implement an asynchronous digital notary service. Anybody who needs certification of any digital document creates a message digest (like MD5 or RIPEMD160) of that document and submits it to the GNotary service by email. GNotary signs this email digitally (using GnuPG), retains a copy of the certified and time stamped message, and mails it back to the sender, optionally with the public key attached to allow the sender to verify the signed document. At regular intervals, the GNotary server creates message digests of its own logs and distributes them among other GNotary servers, thus making it virtually impossible to forge the chain of evidence that authenticates a submitted document.
Drugref is a collaborative effort to create and maintain a database of pharmaceutical reference information, tagged by language, country, and reference source. A Web interface written in PHP4 allows the community of health professionals to maintain and review content. The database structure, implemented in PostgreSQL, is designed to facilitate automated decision support. "Tagging" allows one to import information from any source in parallel, thus allowing drugref to work as a generic interface to any kind of (comercially or freely) available drug reference information.
The Sample Inventory Program (SIP) is a laboratory inventory management system (LIMS) for Zope. Many integration tests exist for various aspects of the SIP application, ranging from command line importing of samples and project configuration to CSV Web-based importing of sample modifications.
Aeskulap is a medical image viewer. It is able to load a series of special images stored in the DICOM format for review. It is able to query and fetch DICOM images from archive nodes (also called PACS) over the network. The goal of this project is to create a full open source replacement for commercially available DICOM viewers. It is based on gtkmm, glademm, and gconfmm and designed to run under Linux. Ports of these packages are available for different platforms. It should be quite easy to port It to any platform were these packages are available.
