Regress Pro is scientific and industrial software that can be used to study experimental data coming from spectroscopic ellipsometers or reflectometers. The program has been developed mainly looking to the application of thin film measurement in semiconductor industry. The software is suitable both to determine the thickness of the layers and to determine the optical properties of dielectric materials.
ArtTk is a graphic library based on Java/Swing offering an open development toolkit intended specifically for scientific and technical applications. It provides a set of widgets and functional modules a set of support modules (helpers) permitting dynamic definition of menus and tool bars from simple XML configured files, and supporting tooltips, icons, action commands, etc.; a very adaptable generic desktop, facilitating the assembly of Swing components in a specialized GUI; an extended Grid layout to simplify the development of advanced scientific applications; and a set of scientific and technical widgets, such as a dynamic memory footprint monitor, simple key-values based fields editors, a generic color gradient editor, etc.
Cassandra is a scientific data viewer based on VTK. Cassandra provides dynamic interaction with the VTK pipeline and enables the user to load plug-ins dynamically in order to perform specific tasks in data manipulation and visualisation. Cassandra is open and modular, and can easily be extended to new filters through a set of dynamically loadable plug-ins. A plug-in template is provided to help users to develop and share their own plug-ins. This approach allows users to perform complex filtering without any specific knowledge of VTK or C++.
San Le's Free Computational Electromagnetics (SLFCEM) is a package of scientific software for use in computational electromagnetics. Command-line driven calculation engines are separate from the GUI components and can be used independently. It includes two of the basic finite elements types, 4 node quad and 3 node triangle. Each element type has a unique GUI specific to the element. Modal analysis for solving the waveguide problem is done using edge based elements. There is also code for generating edge connectivity. The algorithm used is a combination of Lanczos for tridiagonalization of the system, as well as QR to calculate the resulting eigenvalues. In addition to skyline storage and LU decomposition, calculations are also made using the Conjugate Gradient Method.
