Pulga is a program for numerical simulation of dynamical systems. It is designed to provide a way for students and researchers who study dynamical systems to model them on a computer and analyze them numerically without the difficulty of traditional computer programming languages.
Ojax provides an OAI-PMH harvester to harvest metadata from multiple repositories and builds a single searchable Lucene index of this data. OJAX provides a dynamic user experience enabled by Ajax and full OpenSearch integration with the IE 7 and FireFox 2 search fields. It supports OpenSearch Discovery, OpenSearch Atom results, and OpenSearch Search Suggestions. Loosely coupled Web Services and OpenSearch Atom standard allow integration with a range of VLEs, CMSs, institutional repositories, and portals.
The Enterprise Sign On Engine (ESOE) allows an enterprise to meet its goals for identity management, single sign on, authorization, federation, and accountability for resource access in a very extensible manner. The ESOE is built using the OASIS SAML 2.0 specification, and the ESOE's powerful authorization engine is built around a reduced version of the OASIS XACML 2.0 standard called Lightweight eXtensible Authorization Control Markup Language or "LXACML".
Amiba is a Gene Expression Programming (GEP) framework for Java. GEP is, like genetic algorithms, a branch of evolutionary computing. The framework separates the process of evolution from the process of interpretation of the chromosome, allowing the use of various schemes. For example, graphs may be used as terminals and graph operations as operators in the chromosome instead of the usual double precision numbers. It implements mutation, transposition, and recombination. Options and rates are easily configured through an XML file. A mechanism to load fitness cases in bulk is also provided.
The Spiffy Framework is a collection of well-tested and often used helper methods and utility classes. Such methods and classes solve existing and recurring practical problems, and remedy annoying features of the Java language or its frameworks. The value of this framework is not only the code, but also the ideas for solutions to the problems. The goals are to collect and centralize "utility abstractions", and to serve as a repository of knowledge/smart ideas for programmers to learn.
Piggydb is a flexible and scalable knowledge building platform that supports a heuristic or bottom-up approach to discover new concepts or ideas based on your input. You can begin with using it as a flexible outliner, diary or notebook, and as your database grows, Piggydb helps you to shape or elaborate your own knowledge. Piggydb is a Web application provided as a self-contained package that contains a Web server and database engine.
