ThermoCalc is a program for calculating thermal dissipation (heat loss) of a room, based of wall materials used for building the walls

Alignment solver is a utility to solve alignment of Road, Rail or Tunnel.

VHDL and Verilog HDL are standards languages for hardware description. Sometimes is necessary to share the source HDL file but maintaining a little level of control and protection of the intellectual property. This tool generate obfuscated code that is almost unreadable to humans, but is still readable to compilers and simulators. This tool use GHDL (https://sourceforge.net/projects/ghdl-updates/), HDLObf (https://sourceforge.net/projects/hdlobf/), Icarus Verilog (https://sourceforge.net/projects/iverilog/) and was created in Lazarus (http://www.lazarus-ide.org/)

PangInput is a simple application to help you in typing characters from different languages in unicode. Three methods are available: 1) a virtual keyboard, mapping specific characters to each key on your keyboard; 2) custom character sets, which you can select by clicking on them; 3) macro sets, allowing input of complex scripts - basically mapping a latin transcription to the actual writing of characters or words.

This app allows build by introducing chemical compunds or import from a database equations of chemical reactions and balance them. Also it makes stoichiometric calculations with the balanced equation Do stoichiometric calculations on the balanced equation. Results can be saved in a text file. Also, there is an editable database of chemical elements. It is an integrated environment for aspects that usually are treated separately: Balancing of chemical reactions and stoichiometric calculations with chemical compounds based on the balanced equation

This app sets and gets the plane height and slope. You can see, store, load and plot plane test results to observe the rolling/sliding phenomen.
