libcfp analyzes and parses the syntax of a user-supplied chemical formula in ASCII notation. It does not know anything about the semantics of real world physical element characteristics. But it requires no external library dependencies and uses namespace std:: only. Furthermore, it uses UnitTest++ during development to ensure consistent behavior of formula parsing.
SLD Calculator is a GUI to calculate the characteristics of chemical compounds, especially the Neutron and X-Ray scattering length densities that are often required to know in scattering experiments. Furthermore, it offers internationalization support and is capable of switching the language at runtime.
Dr. Higgins will teach you and help you teach yourself any language. It works like a quiz, asking you the translations of words and keeping score of your correctness. It includes a number of quizzes for self-study in different languages (English, Spanish, Finnish, and a bit of Japanese). It's very easy to add your own lists, thanks to a simple file format.
new-words is a script that helps you to control your vocabulary and find unknown words in texts before you start to read them. It is intended to be run in a console; the interactive part of the work is done by means of a text editor (vim by default). It features: words frequency information about words in a text; users vocabulary control; support for several languages; dictionary software integration; and the ability to make notes for unknown words.
eXaminator generates multiple choice exams for use with LaTeX. A collection of questions in a simple plain text format must be supplied. After specifying how many questions should be taken from each collection file, it will choose from them randomly and maintains a history (in a hidden file in the local directory) to guarantee that questions are reused as seldom as possible. Questions can also include pictures.
The PARSEC (Preliminary Analysis of Revolutionary Space Exploration Concepts) CEE (Collaborative Engineering Environment) creates a single-user interface for engineers and scientists to work together to design launch vehicle and spacecraft concepts. The interface allows for seamless integration of design tools for any discipline as well as communication with other team members. Data storage and maintenance is handled automatically. The interface gives users the ability to run multiple design codes and iterative analyses. Branching and other logic operations are also supported. Some data reduction ability is provided as well.
