MIDI Data Miner 3
MIDI Data Miner uses a neural network to learn correlations between notes and control changes in a MIDI file. more>>
MIDI Data Miner uses a neural network to learn correlations between notes and control changes in a MIDI file.
After training MDM can augment a live MIDI stream, adding control changes based on notes received.
Briefly: use MDM by connecting a MIDI device, open preferences and set MIDI input and output ports. Open a MIDI file, create a new neural net and train. Now play notes on your MIDI device, MDM will automatically add control changes.
MDM creates a collection of note and controller pairs from the file and uses them to train a net. The notes are used as inputs and the controls as outputs. The window is the number of previous notes considered when determining the output for the current note. Larger windows give less predictable more interesting responses. Enter a number in the window box and press enter to set the window size.
This is an early alpha release, buggy and incomplete. Please send feedback! Note that this alpha version only reads from the first track in a MIDI file, and only uses the first controller. Look at the included MIDI file in the working/midi folder for details.

Ganymede 1.0.12
Ganymede is a GPLed Network Directory Management System. more>>
GANYMEDE is a portable and customizable network directory management system, released under the GNU General Public License. It is free software. Ganymede is written in Java, and the Ganymede clients can be run on any system with JDK 1.1.7 or better. The Ganymede server is designed to run on a UNIX-type system, but can be run on almost any Java-supporting operating systems with the proper support scripts.
Ganymede is designed to manage network directory services such as NIS, DNS, Netinfo, and LDAP. The Ganymede server contains an object database of your network directory data, which users and admins can browse and edit using a polished GUI client. Whenever a change is committed to the database, the Ganymede server dumps out a bunch of data files and runs backend scripts to update your network directory services. All changes are logged, and Ganymede can send email to your users and administrators notifying them of account activity.
Ganymede is both multithreaded and multi-user. Many users and admins can be browsing and making changes to the Ganymede database simultaneously. The Ganymede server supports transactions, and transparently handles locking and concurrency issues to guarantee referential data integrity during concurrent editing. Ganymede supports fine-grained delegation, so that you can allow arbitrary subdivision of authority over your network directory services. If you want to have a single NIS domain for your organization but you want certain administrators to be able to edit only certain user accounts, Ganymede makes it easy.
Finally, Ganymede is highly customizable. You can customize the servers schema definitions to handle whatever sort of directory data you want to manage, and data can be imported from any source you like using Ganymedes flexible XML interface. You can create custom Java classes to generate any sort of data files, and your own back-end builder scripts in your favorite scripting language to handle the distribution of directory updates. You can create administration tasks to be run automatically by the Ganymede scheduler, and you can create plug-in classes to oversee almost every aspect of the editing process.
At ARL:UT, we use Ganymede to manage NIS, DNS, a Windows NT domain controller, Samba, Sendmail, tacacs, and LDAP. If you have a lot of network directory services that youd like to unify without having to rearchitect your network systems around LDAP or Active Directory, Ganymede may be the tool for you.

ProM 4.0
ProM is a new era in process mining tool support. more>>
ProM is a new era in process mining tool support.
Process Mining research is concerned with the extraction of knowledge about a (business) process from its process execution logs. Process Mining strives to gain insight into various perspectives, such as the process (or control flow) perspective, the performance, data, and organizational perspective (The processmining.org web site has more in-depth information and scientific publications available).
ProM is an extensible framework that supports a wide variety of process mining techniques in the form of plug-ins. It is platform independent as it is implemented in Java, and can be downloaded free of charge. We welcome and support practical applications of ProM! Note that the ProM framework is issued under an open source license, namely the Common Public License (CPL), and we invite researchers and developers to contribute in the form of new plug-ins.
Currently, there are already more than 90 plug-ins available, and we support the import of (and the conversion between) several process modelling languages, such as:
- Petri nets (PNML, TPN)
- EPCs / EPKs (Aris graph format, EPML)
- YAWL
- (and many more)
There are mining plugins, such as:
- Plugins supporting control-flow mining techniques (such as the Alpha algorithm, Genetic mining, Multi-phase mining, ...)
- Plugins analysing the organizational perspective (such as the Social Network miner, the Staff Assignment miner, ...)
- Plugins dealing with the data perspective (such as the Decision miner, ...)
(and many more)
Furthermore, there are analysis plugins dealing with:
- The verification of process models (e.g., Woflan analysis)
- Verification of Linear Temporal Logic (LTL) formulas on a log
- Checking the conformance between a given process model and a log
- Performance analysis (Basic statistical analysis, and Performance Analysis with a given process model)
- Finally, ProM sports a large array of log filters, which are a valuable tool for cleaning logs from undesired, or unimportant, artefacts.
Enhancements:
- This release features fundamental framework improvements and the addition of a major set of new plugins.
- The performance of log reading has been improved dramatically, introducing live modification of logs and random access.
- More than 70 newly added plugins substantially extend the analysis feature set.

BRL-CAD 7.10.0
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor. more>>
BRL-CAD project is a powerful Constructive Solid Geometry (CSG) solid modeling system. BRL-CAD includes an interactive geometry editor, ray tracing support for rendering and geometric analysis, network distributed framebuffer support, image-processing and signal-processing tools. The entire package is distributed in source code form.
Since the late 1950s, computers have been used to assist with the design and study of combat vehicle systems. The result has been a reduction in the amount of time and money required to take a system from the drawing board to full-scale production as well as increased efficiency in testing and evaluation.
In 1979, the U.S. Army Ballistic Research Laboratory (BRL) (now the U.S. Army Research Laboratory [ARL]) expressed a need for tools that could assist with the computer simulation and engineering analysis of combat vehicle systems and environments. When no existing computer-aided design (CAD) package was found to be adequate for this purpose, BRL software developers began assembling a suite of utilities capable of interactively displaying, editing, and interrogating geometric models. This suite became known as BRL-CAD.
Now comprising over one-half million lines of C code, BRL-CAD has become a powerful constructive solid geometry (CSG) modeling package that has been licensed at over 2,000 sites throughout the world. It contains a large collection of tools, utilities, and libraries including an interactive geometry editor, raytracing and generic framebuffer libraries, a network-distributed image-processing and signal-processing capability, and a customizable embedded scripting language. In addition, BRL-CAD simultaneously supports dual interaction methods, one using a command line and one using a graphical user interface (GUI).
A particular strength of the package lies in its ability to build and analyze realistic models of complex objects using a relatively small set of "primitive shapes." To do this, the shapes are manipulated by employing the basic Boolean operations of union, subtraction, and intersection. Another strength of the package is the speed of its raytracer, which is one of the fastest in existence. Finally, BRL-CAD users can accurately model objects on scales ranging from the subatomic through the galactic and get "all the details, all the time."
The application side of BRL-CAD also offers a number of tools and utilities. They primarily concern (1) geometric conversion, (2) geometric interrogation, (3) image format conversion, and (4) command-line-oriented image manipulation. The following is a list of the major BRL-CAD tools and utilities.
- MGED (Multiple-Device Geometry Editor) ? BRL-CADs graphics editor. (For detailed guidance on the use of MGED as well as a list of all the MGED commands currently available, see Butler et al. [2001].)
- Tools for raytracing and interrogating raytraced geometric objects.
- rt ? the main raytracer for rendering images in BRL-CAD.
- nirt ? a package for firing rays interactively and getting information about what the rays run into.
- remrt ? a network-distributed raytracing package.
- An assortment of geometric converters to convert to and/or from other geometry formats, including Euclid, ACAD, AutoCAD DXF, TANKILL, Wavefront OBJ, Pro/ENGINEER, JACK (the human factors model for doing workload/usability studies), Viewpoint Data Lab, NASTRAN, Digital Equipments Object File Format (OFF), Virtual Reality Mark-up Language (VRML), Stereo Lithography (STL), Cyberware Digitizer data, and FASTGEN4.
- bwish ? a Tcl/Tk interpreter in a windowing shell with enhancements compiled into it for accessing BRL-CAD libraries. It also includes various other extensions to the Tcl language.
- irprep ? produces input to the PRISM (Physically Realistic Infrared Simulation Model) code.
- JOVE (Jonathans Own Version of Emacs) ? a fast, light implementation of Emacs.
- Applications for displaying images of various types on the framebuffer application and retrieving data from that framebuffer into images of various types.
- Tools for generating geometry for common objects such as fences, walls, and geometric mathematical oddities (e.g., the sphereflake shown in Figure 2 in Section 4).
- Data manipulation programs to (1) convert integers to floats, floats to doubles, etc. (e.g., cv); (2) perform mathematical operations on file elements (e.g., imod, umod, and dmod); (3) compute statistics of file elements (e.g., istat, ustat, and dstat); etc.
- Utilities for building animation scripts ? keeping track of columnar data and interpolating it to allow one to produce input to the rt program to render multiple items for animation.
- Utah Raster Tool Kit ? image manipulation of all RLE-based images.
- Programs for manipulating images and converting between different image file types. The two primary BRL-CAD types are pix (24-bit red, green, and blue [RGB] color images) and bw (8-bit greyscale images). Converters exist for various image formats including alias, png, ppm, etc.
- Programs for filtering images, doing histograms on the image data, and extracting rectangles from the images.
- Tools for combining two images and blending them together. (These tools were created before good image editing tools for video production were available; today users would typically load the images directly into a video editing package.)
Enhancements:

In 1979, the U.S. Army Ballistic Research Laboratory (BRL) (now the U.S. Army Research Laboratory [ARL]) expressed a need for tools that could assist with the computer simulation and engineering analysis of combat vehicle systems and environments. When no existing computer-aided design (CAD) package was found to be adequate for this purpose, BRL software developers began assembling a suite of utilities capable of interactively displaying, editing, and interrogating geometric models. This suite became known as BRL-CAD.
Now comprising over one-half million lines of C code, BRL-CAD has become a powerful constructive solid geometry (CSG) modeling package that has been licensed at over 2,000 sites throughout the world. It contains a large collection of tools, utilities, and libraries including an interactive geometry editor, raytracing and generic framebuffer libraries, a network-distributed image-processing and signal-processing capability, and a customizable embedded scripting language. In addition, BRL-CAD simultaneously supports dual interaction methods, one using a command line and one using a graphical user interface (GUI).
A particular strength of the package lies in its ability to build and analyze realistic models of complex objects using a relatively small set of "primitive shapes." To do this, the shapes are manipulated by employing the basic Boolean operations of union, subtraction, and intersection. Another strength of the package is the speed of its raytracer, which is one of the fastest in existence. Finally, BRL-CAD users can accurately model objects on scales ranging from the subatomic through the galactic and get "all the details, all the time."
The application side of BRL-CAD also offers a number of tools and utilities. They primarily concern (1) geometric conversion, (2) geometric interrogation, (3) image format conversion, and (4) command-line-oriented image manipulation. The following is a list of the major BRL-CAD tools and utilities.
- MGED (Multiple-Device Geometry Editor) ? BRL-CADs graphics editor. (For detailed guidance on the use of MGED as well as a list of all the MGED commands currently available, see Butler et al. [2001].)
- Tools for raytracing and interrogating raytraced geometric objects.
- rt ? the main raytracer for rendering images in BRL-CAD.
- nirt ? a package for firing rays interactively and getting information about what the rays run into.
- remrt ? a network-distributed raytracing package.
- An assortment of geometric converters to convert to and/or from other geometry formats, including Euclid, ACAD, AutoCAD DXF, TANKILL, Wavefront OBJ, Pro/ENGINEER, JACK (the human factors model for doing workload/usability studies), Viewpoint Data Lab, NASTRAN, Digital Equipments Object File Format (OFF), Virtual Reality Mark-up Language (VRML), Stereo Lithography (STL), Cyberware Digitizer data, and FASTGEN4.
- bwish ? a Tcl/Tk interpreter in a windowing shell with enhancements compiled into it for accessing BRL-CAD libraries. It also includes various other extensions to the Tcl language.
- irprep ? produces input to the PRISM (Physically Realistic Infrared Simulation Model) code.
- JOVE (Jonathans Own Version of Emacs) ? a fast, light implementation of Emacs.
- Applications for displaying images of various types on the framebuffer application and retrieving data from that framebuffer into images of various types.
- Tools for generating geometry for common objects such as fences, walls, and geometric mathematical oddities (e.g., the sphereflake shown in Figure 2 in Section 4).
- Data manipulation programs to (1) convert integers to floats, floats to doubles, etc. (e.g., cv); (2) perform mathematical operations on file elements (e.g., imod, umod, and dmod); (3) compute statistics of file elements (e.g., istat, ustat, and dstat); etc.
- Utilities for building animation scripts ? keeping track of columnar data and interpolating it to allow one to produce input to the rt program to render multiple items for animation.
- Utah Raster Tool Kit ? image manipulation of all RLE-based images.
- Programs for manipulating images and converting between different image file types. The two primary BRL-CAD types are pix (24-bit red, green, and blue [RGB] color images) and bw (8-bit greyscale images). Converters exist for various image formats including alias, png, ppm, etc.
- Programs for filtering images, doing histograms on the image data, and extracting rectangles from the images.
- Tools for combining two images and blending them together. (These tools were created before good image editing tools for video production were available; today users would typically load the images directly into a video editing package.)
