aicwl is an Ada library that is intended for designing high-quality industrial control widgets for Ada applications. The widgets are composed of transparent layers drawn by cairo. The widgets are fully scalable graphics. A time controlled refresh policy is supported for real-time and heavy-duty applications. The library supports caching graphical operations and stream I/O for serialization and deserialization. Ready-to-use gauge and meter widgets are provided as samples as well as an editor widget for WYSIWYG design of complex dashboards. The software is based on GtkAda and cairoada, the Ada bindings to GTK+ and cairo.
Apache uimaFIT provides Java annotations for describing UIMA components which can be used to directly describe the UIMA components in Java code without the need for traditional UIMA XML descriptors. This greatly simplifies refactoring a component definition (e.g., changing a configuration parameter name). It also makes it easy to instantiate UIMA components without using XML descriptor files by providing convenient factory methods. It is ideal for testing UIMA components because the component can be easily instantiated and invoked without requiring a descriptor file to be created first.
nan_payload is an Ada package that provides support for using the NaN payload field from IEEE-754 floating point. Storing 'non-available' errors as well as other symbolic values instead of any of the numbers in numeric arrays is necessary in many statistical applications. The package allows you to read and write the part of NaN IEEE754-64 bit values known as 'the payload', which is 51 bits long, and also to treat the long_float type as an implicit tagged type by storing tags and values in the payload. Calendar dates with ms resolution as well as 9-letter symbols and some not available/error codes are provided as subtypes. Formatted output with Fortran-like descriptors as well as reading values from strings for these types is also provided.
Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. The API is deliberately similar to Matlab's. Integer, floating point, and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK and ATLAS numerics libraries. A delayed evaluation approach, based on template meta-programming, is used (during compile time) to combine several operations into one and reduce or eliminate the need for temporaries.
