Numerical models for chemical and process engineering
NCE Calculation Framework is a library of routines, models and data applicable to chemical and process engineering calculations, written in Java.
-- NEW -- www.chesolver.com *ONLINE CALCULATORS*. A set of solvers to perform calculations consistently on any device, from smart-phone to desktop.
The project includes the following ready to use software all based on the same core library:

ICE is a simple mathematical calculator with very useful shortcuts for Engineer: works natively with tolerance, can run Monte Carlo analysis, uses engineer notation, includes most of the day by day functions used by engineers.
JBernstein: Exploration techniques for non-linear constraint checking
...Concerning performance, the tool enables to check all examples in the PVS Bernstein testsuite within a second, which can be an order of magnitude faster than some other tools such as QEPCAD or REDLOG.
Although JBernstein uses double, it offers automatic error-estimation capabilities (experimental) so that the generated result is correct (the solver may return unknown when the error-estimate is too large)
Interval Analysis is a collection of interval analysis tools, allowing for robust root-finding and tracking of bounds of numerical error due to uncertain inputs and floating-point error.
